Steak Recipe Using Ninja Foodi Smart Grill

So, I just got the Ninja Foodi Smart Indoor Grill which doubles as an air fryer and mini oven. I have another cheaper indoor grill but tends to produce smoke and always triggers my smoke sensor. So far, though the Ninja grill is larger, it hasn’t emitted any smoke nor triggered my smoke sensor and produces better grill results.

Here’s how to make steak using it.

Ingredients for Marinade

Preparation

  1. Get your steak (minimum 1″ thick and preferably from Costco).
  2. Put that steak in a ziploc bag.
  3. Mix water and sauce and pour into the ziploc bag.
  4. Zip the bag and turn a few times and let marinate for 1 to 8 hours.

Cooking Instructions

  1. Insert thermometer into middle of side of steak such that the tip is at the center of the thickest part.
  2. Turn on the Ninja grill by pushing the grill button.
  3. Click the left up/down arrows to choose a doneness level. I like medium rare.
  4. Push the thermometer / preset button to start the preheat phase
  5. Sprinkle salt on both sides of the meat.
  6. When preheating is done, it will beep and tell you to insert the steak. Do so.
  7. Sometime later, it will beep and tell you to flip the steak. Do so, preferably using silicone-tipped tongs.
  8. Sometime later, it will be done and tell you to get the steak out. Do so and wait 5 minutes before enjoying.

Grill Vegetables (optional)

To complement the steak, you can grill some vegetables in the Ninja grill also. Here are the veggies that grill well.

  • Asparagus
  • Zucchini
  • Tomatoes
  • Onions
  • Bell pepper
  • Jalapeno peppers
  • Tomatillo peppers
  • Corn

Instructions

  1. Cut vegetable in half or in slices.
  2. Remove spicy seeds from peppers.
  3. Slather with / baste in oil.
  4. Sprinkle coarse salt and pepper.
  5. Turn on Ninja grill
  6. Push grill button
  7. Push right up/down to set the time to 6 minutes
  8. Push thermometer / preset button twice to skip preheating
  9. Put veggies in grill
  10. The grill will beep when done.

Quickly Create Photo Slideshow Video

This tutorial uses Corel VideoStudio Pro.

1. Add photos to project

Sort the photos as desired, usually by date, so they appear in chronological order.

2. Select and drag photos to video track

All photos will be added to the video track

3. Change duration of each photo

If the duration of each photo is too short or long, select all photos, right click and click on “Change Photo Duration …”. This will change the duration for each and all photos.

4. Add a transition effect

Choose a transition (a simple “crossfade” is the best”), right click and click on “Apply current effect to video track”.

This will result in the transition being applied to all photos.

5. Add Pan and Zoom effect

Select all photos, right click and click on “Auto Pan & Zoom”.

6. Drag audio file to music track

You can find some background music from Sound Cloud.

7. Add intro slide

Click “Instant Project” icon, click on “Beginning”, choose a template, right click and click on “Add at the beginning”.

8. Edit intro slide

Since the intro slide is a template, you will see placeholder content.

Drag a photo to the placeholder clip and hold “Ctrl” to replace the clip. This will cause the photo to be formatted to fit the template.

Double-click the text clip to edit the text of the intro template.

9. Add end slide

This process is the same as for adding the intro slide but click on “Add at the end” instead.

10. Add text to some photos

Click “Title” and then pick a title template. The one with a semi-transparent background is good. Drag it to the Title track where you want the text to appear.

11. Change text and background color

This title template animates the text.

Convert it to a simple fade in and out by clicking on the “Attribute” tab in the Options Panel for the title, click on “Attribute” tab, click on “Animation”, and disable animation by unchecking the “Apply” checkbox.

The background of the text is too light so let’s darken that semi-transparent bar. Double-click on the title clip and in the Options Panel, click the “Edit” tab, and click on the black color in the Text Backdrop context menu as shown in the screenshot below.

Double-click on the title clip again and edit the text.

12. Add more text

Copy and paste the text clip to other photo clips and edit the text.

13. Render video

Click the “Share” tab, choose a setting, and click “Start” button.

Batch Search and Replace in VisualStudio Code

Have you ever needed to do search and replace multiple times against the same file or set of files. If so, the Batch Replacer extension for VisualStudio Code makes this very simple.

  1. Open a folder or file in VisualStudio Code
  2. Create a new file (no need to save it) and enter some search and replace instructions, e.g.

In the example above, I want 3 different replacements done in the order shown and I only want the replacements done to a specific file. The “in” command is followed by the path of the file relative to the root of the workspace open in VS Code. If the file is open, you can get it by right clicking on its tab and selecting “Copy relative path”.

3. Execute the replacer script

To run the batch replacements, you active tab must be the tab containing your replacement instructions. Then, hit CTRL+SHIFT+P -> Batch Replace. A status window will appear in the bottom right corner telling you how many files have been modified. If you want to batch replace across all files in your workspace, don’t include the “in” instruction.

How to Make a Quality Video Presentation With Slides and Someone Talking

In this article I explain how to create a video presentation like what you see below. Features of this video include:

  • custom background (still image or video)
  • the presenter on one side
  • presentation slides on one side
  • clear audio

Equipment

Following is the equipment I used to make this type of video.

Video Editing Software

Corel VideoStudio Ultimate – $80

Presentation software

Google Slides (online) – Free

Wireless Presenter Pen

This is used to change slides wirelessly.

Generic Pen – $11

Green Screen

I bought a 7’x10′ green screen. I got just the fabric because I semi-permanently attached it to my garage ceiling since I don’t plan on using anywhere else.

Generic green screen – $21

Learn how I set up my green screen

If you want a green screen that comes with a stand, there are many options online (Amazon, etc) but they are more expensive.

Lighting

Lighting is key to getting good chroma key results and a good video overall. In particular, you want to eliminate shadows as much as possible.

Generic Softbox Photography Lighting Kit – $67

Background Image or Video

You can replace the green background with a still image or a video. One stock photo and video site is ShutterStock.

Video Camera

I just use my smartphone (Google Pixel 3 XL) to take videos.

Microphone

In order to get clear audio, you need a microphone. You can get one with a 3.5 mm jack or a USB C jack, depending on your recording device.

USB C Lavalier Mic 10 feet long – $15

iBower Lavalier Microphone (IBO-MIC100) – $26

If your phone has a USB-C jack instead of a 3.5mm jack, you’ll need an adapter and an extension cable. I’m using the Apple – USB-C to 3.5mm Headphone Jack Adapter – White ($9) and a 16′ long TRRS 4 pole 3.5 mm male to female audio extension cable ($9)

Important: the audio cables MUST be 4 poled TRRS cables / adapters, not 3 pole TRS cables / adapters. The extra pole is for the microphone.

Video Recording App

I use Cinema FV-5 to record video from my phone because it supports an external mic on my Pixel 3 XL.

Cinema FV-5 ($2.50)

An alternative to this app is Open Camera (free).

Tripod

A tripod is necessary to hold your smartphone at the correct height to take videos.

AmazonBasics Tripod – $18

Tripod Mount Adapter for Smart Phones

This mount will allow you to hold your smartphone to the tripod.

Generic Tripod Mount Adapter for Smartphones – $10

Laptop

I use a Lenovo with 16 GB of RAM and an SSD both specs of which are necessary for video editing performance. I got mine on sale from Costco.

Laptop Stand

I’m using a sheet music stand as a laptop stand.

GLEAM Sheet Music Stand Metal with Carrying Bag – $28

Workflow

The overall workflow is as follows:

  1. Create presentations slides and export them as images
  2. Record video
    1. Stand in front of the green screen with softbox lights on
    2. Clip lavalier mic to shirt and connect it to smartphone on tripod (if necessary, using USB extension cables and an adapter).
    3. Place laptop on laptop stand outside the camera field of view
    4. In video recording app, ensure audio source is set to “external mic”.
    5. Press record and speak while reading and changing slides remotely using the wireless presenter pen
  3. Create final presentation video

Google Slides Tips

Export all slides as images

Creating slides in Google Slides is very similar to how you create them in other presentation apps like MS Powerpoint. In Google Slides, however, if you want to export all slides as images, you need an add-on. I use Slides Toolbox by Digital Thoughts. Once you’ve added that add-on, you can open it

and choose to export all slides as JPG or PNG images.

Set a background with transparency

Notice how in my final rendered video, the background video shows through the slides.

That was accomplished by setting the transparency of the background in Google Slides to around 70% opaque (30% transparent). If you want a semi-transparent background, then you must export the slides as PNG images rather than JPG images.

Test Slides

Download a sample presentation with semi-transparent background in ODP (OpenDocument Presentation) format which you can import into Google Slides.

You can also download the test slides in PNG format for importing into VideoStudio.

Video Recording Tips

  • Position the lavalier mic such that you don’t hear the sound of you breathing.
  • Stand far from the camera to record more of yourself. You can always crop the video later.
  • If you have a fast computer with plenty of SSD space, record your video in 4K for ultra hi definition (UHD) resolution. Otherwise, record at 1080p hi definition (HD).
  • Using the softbox lights, and other lights, if necessary, eliminate as many shadows as possible. For example, the picture below shows dark shadows which will be difficult to remove when you’re editing the video.
  • In the Cinema FV-5 video recording app, set audio source to “external mic”. When you push the cable into your phone, the wired microphone icon near the top-right corner appears in the app. This tells me the audio source will come from the external mic.

Video Editing Tips

NewBlueFX Chroma Key Filter

Use the NewBlueFX Chroma Key filter in VideoStudio to key out the green background. Read my blog post titled NewBlueFX Chroma Key to Easily Remove Green Screen in Video for step-by-step instructions.

Organize assets

Put all assets in a single folder. Below is a screenshot of my video assets which includes

  • 1 background video of the earth rotating
  • 5 semi-transparent presentation slides
  • 1 video of my giving a presentation in front of a green screen

For the background video, I picked a video that could be looped seamlessly.

Smart Proxy

Make sure to enable Smart Proxy in VideoStudio to improve video editing performance. For more information, read my blog post titled Improve Performance When Working with Large Videos in Corel VideoStudio.

Export

When you export the video, you will have many settings and export presets to choose from. For each preset, you can see the estimated output file size. There’s no point in choosing a high quality output if the source video is low quality. In Windows Explorer, right click on the foreground video and click Properties > Details to see the video specs. The screenshot below shows that my foreground video taken on my phone was 1920×1080 with a bit rate of 22254 kbps (~22 Mbps) and a frame rate of 30 frames per second (fps).

For this, I chose the following spec which gave an estimated output file size of 252 MB for a 13 minute video.

Workflow

In VideoStudio, my workflow is

  1. Create a new project
  2. Add all assets (videos, slides, etc) to the project
  3. Verify SmartProxy is enabled
  4. Add an overlay track so that I have 2 overlay tracks
  5. Drag the background video to the Video track
  6. Drag the slides to the Overlay 1 track in order
  7. Drag the foreground video with the green screen to the Overlay 2 track
  8. Crop the foreground video as necessary
  9. Using NewBlue FX Chroma Key filter, remove the green background so that it’s transparent
  10. Copy and paste the background video multiple times to span the duration of the foreground video
  11. In the Preview panel, drag the foreground video to the left
  12. In the Preview panel, drag the slides to the right and line them up using the grid that appears
  13. Preview the composite video and make changes, as necessary
  14. Export the video

How to Take Pictures to Get the Right Shot

Most people take pictures by just manually taking a shot when they are ready. Since many things could go wrong with taking just a single shot, e.g. the subject blinks or yawns, a car drives by, etc, then some people will take multiple shots manually – maybe 2 or 3. However, this still doesn’t necessary offer the best shot because the subject may not like how they look in a particular stance or the lighting may not be at their particular angle. Also, photos of people just looking straight at the camera or posing often look boring, as opposed to photos that appear to be taken randomly or without the subject knowing.

Snapshot from Video

To resolve this, you could take a 4K video from your mobile phone, open the video in a video play like VLC, scrub through the video and when you are on a frame you like, take a snapshot (not a screenshot).

Pros:

  • many frames to choose from (usually 30 frames per second)

Cons:

  • large file size
  • must open video and scrub through and pic from you like
  • videos are generally more compressed than images

Series of Still Images Taken Automatically

To get around the cons of the video approach, you can take a series of still images and just pic the ones you like. This is sometimes called “burst” mode. Ideally, you would be able to

  • set a delay timer (if you will put the camera down and be in the picture yourself)
  • set how many pictures to take, e.g. a max of 5 or 10 pictures or unlimited if you want to stop taking pictures when you push a button
  • an time interval between which photos will be taken, e.g. take a picture every 0.5 seconds, 1 second, 5 seconds, etc.

One app that meets these requirements is Open Camera. It’s free and looks well made. In the screenshot below. I enabled Face detection so that if the subject moves, like when you’re taking a video, the subjects face should always be in focus. I set Repeat to 10x to take a maximum of 10 pictures and I set Repeat mode interval to 1s so a picture will be taken automatically every 1 second.

In this example, I’d end up with 10 pictures. I could then just pick the best one and delete the rest.

Comparison

To compare the picture quality of this method verses taking stills from a video, consider the following photos.

From video
From a series of still images

If we zoom in to 100% and focus on a small section, you’ll notice there are more artifacts and blurriness in the still taken from the video, not to mention the contrast and color looks much better in the still shot.

From video
From a series of still images

If I enlarge the images, the artifacts in the video snapshot become much more apparent.

From video
From a series of still images

If you set the Repeat to Unlimited and Repeat mode interval to No delay, the app will take as many pictures as it can until you push the stop button. For comparison, a 10 second 4K video consumed 61 MB whereas 10 seconds of unlimited, no delay pictures produced 23 images totaling 45 MB.

The next time you want to take a picture, you may want to try Open Camera and take a series of many pictures as your subject walks around or behaves naturally.

Get Silky, Shiny, Soft, Smooth and Frizz-free Hair

A few years ago I tried a product called Leave-in Hair Treatment with Argan Oil by HSI Professional. It came in a red box and bottle.

You just dab a little in the palm of your hand and massage it through your hair and it instantly makes your hair look and feel better. The ingredients are

Cyclopentasiloxane
Dimethicone Crosspolymer,
Argania Spinosa (Argan) Oil,
Fragrance (Parfum)
D&C Red #17 (CI 26100)
D&C Yellow #11 (CI 47000)
Benzyl Benzoate
Benzyl Salicylate
Amyl Cinnamal
Benzyl Salicylate
Butylphenyl Methylpropional
Geraniol
Hexyl Cinnamal

Unsurprisingly, it got many good reviews on Amazon.

Unfortunately, this product has been replaced with a similar but slightly different product. It’s good but definitely not as good as the original formula.

The ingredients are

Cyclopentasiloxane
Cyclotetrasiloxane
Dimethicone Crosspolymer,
Argania Spinosa (Argan) Oil,
Fragrance (Parfum)
D&C Green #6 (CI 61565)
D&C Red #17 (CI 26100)
D&C Yellow #11 (CI 47000)
Benzyl Benzoate
Hexyl Cinnamal
Lillial

The new formula has the same ingredients as the old formula except it’s missing the following

Benzyl Salicylate
Amyl Cinnamal
Benzyl Salicylate
Butylphenyl Methylpropional
Geraniol

To understand the difference and find products that are just as good, if not better, here is a list of products that have similar ingredients. Note that the percent amount of each ingredient is in descending order.

How to Create an Automated Light Show in Sync with Music

Let’s say you have a bunch of songs and for each song, you want to have different colored lights come on and off and/or move around.

In order to do this, you need a few things:

  • Light fixtures
  • DMX Interface
  • DAW (Digital Audio Workstation) software / controller

Light fixtures

There are different types of light fixtures.

Ellipsoidal Reflector Spotlight (ERS)

This type of light is used to highlight certain subjects or stage pieces with a relatively narrow beam angle.

Parabolic reflectors (PAR)

This type of light is used to light up large areas. They come in a variety of lens types to get different beam angles. This light doesn’t have zoom or focus options. This is the most common fixture because it’s the cheapest.

Fresnel

This type of light is a happy medium between a PAR and an ERS. They have a zoom function but not a focus and usually cast a much “softer” light than ERS light fixtures.

Moving Head

This type of light can move. It offers different beam angles for spot (narrow), wash (wide), beam (laser) and hybrid light effects. It is the most versatile stage lighting option.

Above are only some of the more common types of lights.

To hang your lights, you can get a lighting stand with T-Bar.

DMX Interface

DMX (Digital Multiplexing) or, officially, USITT DMX512, is a unidirectional serial data protocol, meaning the signal leaves the controller (computer or lighting board) and travels through all lighting fixtures in a daisy-chain. It was standardized in 1986. DMX networks typically only have one master device on the network, usually the DAW software / controller, and many slave devices — the lights.

DMX Cable

The 5-pin XLR the standard connector.

The reason for five pins is that pin 1 would be the ground, pins 2 and 3 would be data link 1, and pins 4 and 5 were reserved for data link 2 and/or proprietary data. Over the years, the second pair of pins (pins 4 & 5) on the connector stopped being used, since 3-pin DMX proved to be very reliable. This is why you may sometimes see fixtures with a 3-pin, 5-pin, or both connectors on the fixture.

DMX vs Audio/Mic XLR Cables

Some DMX cables are 3-pin cables. Don’t confuse them with 3-pin audio or mic cables. DMX cables use roughly 110-ohms whereas microphone cables are typically around 45 ohms. The different impedance between these cables matters with lighting networks and can cause your lights to either not respond or respond sporadically.

Number of light fixtures per DMX cable

You cannot have more than 32 devices connected on a single chain. If you have more than 32 light fixtures, you would need to use an Opto-Splitter. A splitter like the Chauvet DJ Data Stream 4 will allow you to have 32 devices connected to each DMX output connector. You cannot use Y-cables, as this approach does not electrically isolate the DMX lines and would cause data reflections.

DMX Channels / Universe

A DMX line is limited to a total of 512 channels, which is also called a universe. Each lighting fixture you have uses a number of DMX channels depending on how many parameters the fixture has. Lights can also have multiple personalities, or profiles, depending on how much or how little control you want. Note that the 512-channel limit is independent of the 32-light fixture limit.

Let’s say you have 40 lighting fixtures that use three channels each: you are only using 120 channels total. You can fit these all in the same universe of control, however, if you have more than 32 devices. You would implement an Opto-Splitter and split your devices up among the outputs in whatever configuration you would like, as long as each DMX leg has less than 32 devices on it.

Example

Let’s look at the Chauvet DJ SlimPAR Pro H.

This light has three different personalities, or profiles. It can be used in a 6-, 7-, and 10-channel mode, and again the more channels a fixture uses, the more control you have. Let’s look at 7-channel mode:

  • Channel 1: Dimmer
  • Channel 2: Red
  • Channel 3: Green
  • Channel 4: Blue
  • Channel 5: Amber
  • Channel 6: White
  • Channel 7: UV

Each DMX parameter on a fixture operates independently. Say I was to make this fixture a magenta color. I would turn up channel 2 (Red) and channel 4 (Blue) until I got my desired shade of magenta. However, turning up just these channels on the fixture (2 & 4) would not put out any light. I would also need to turn up channel 1, which is my dimmer that controls the overall intensity. On moving fixtures, this control becomes even more complex, because there are other parameters available, such as Pan and Tilt or gobos, again all independent.

The best way to understand a light’s capabilities is by checking its DMX assignments. For example, the ADJ Starbust’s manual shows this.

Addresses

When setting up a lighting rig, each light fixture needs to be assigned a starting address. If I have four of the same fixture mentioned above in the same personality (7-channel mode), their addresses would be 1, 8, 15, and 22. All 512 channels of data flow through every fixture in a DMX lighting chain so each fixture needs to know which channels control it based on channel addressing.

DAW (Digital Audio Workstation) software / controller

There are many different DAW software, for example, Ableton Live and Pro Tools. They can be used to create music and control lights. This article isn’t about creating music but just controlling lights in sync with existing music. Therefore, the software we’ll use is Show Buddy.

Setup

To sync light effects with music (e.g. an existing mp3 file), we’ll use this setup.

Terminate the DMX cable chain by inserting a DMX terminator into the DMX Out port of the last light fixture.

DMXIS Software

Important terminology

  • Show (group of songs)
    You can create multiple shows. A show typically is the name of a list of songs, e.g. Yanni Concert
  • Bank (a song)
    You can create multiple banks per show. A bank can be the name of a song, e.g. Santorini
  • Preset (a light effect)
    You can create multiple presets per bank. A preset can be the name of a light effect. You can create multiple presets (light effects) for a bank (song) in order of when you want the preset (light effect) to occur during song playback. You can drag presets up and down to order them.

Workflow

  1. Add a light fixture
    If the light fixture you want to add isn’t in the DMXIS library, you can search for it at http://fixtures.dmxis.com/ where you can download user-uploaded DMX light fixes for importing into DMXIS. If you don’t find your fixture there, you can create and upload DMX light specs for your particular fixture. It is just a text file defining channel.
  2. Assign each light fixture to a starting address, e.g.
    • PAR light 1 (3 channels) starts at DMX address 1 (channels 1-3)
    • PAR light 2 (3 channels) starts at DMX address 4 (channels 4-6)
    • PAR light 3 (3 channels) starts at DMX address 7 (channels 7-9)
    • PAR light 4 (3 channels) starts at DMX address 10 (channels 10-12)
  3. Create a “show”, e.g. “Instrumental Songs”
  4. Create a “bank”, e.g. “Santorini”
  5. Create a preset, e.g. “Red”
  6. Adjust the sliders for one or more light fixtures, e.g. by making them show red light
  7. Save (overwrite) the “Red” preset
  8. Repeat steps 4-6 as much as needed

ShowBuddy Software

This software allows you to load audio files (e.g. mp3s) and for each song, place a preset (light effect) created in DMXIS at certain points in the song. Light effects can fade out over a specified amount of time.

Workflow

  1. Add audio files (songs / mp3s) to the Track Library
  2. Choose the DMXIS show to use in the DMXIS show dropdown
  3. Choose a DMXIS bank to use in the list of banks
  4. Choose a DMXIS preset to use in the list of presets
  5. Drag the preset to the wave form at the point you want the preset (light effect) to run
  6. Repeat steps 2-5 as much as needed

Resources

Capture Software

This software allows you to preview light effects.

Workflow

  1. Create a 3D stage
  2. Add one or more light fixtures to the 3D stage
  3. Patch light fixtures (assign them to DMX addresses)
  4. If the light fixture address assignment in Capture matches that in DMXIS, then DMXIS can control the light visualizations in Capture
