requires Mac OSX 10.11 or later: 300mb download

I recommend you put and run the app from your desktop. It saves your video files to where you have the app so that way the video files will be easily found and watched. The app will not work properly in your downloads folder or other places it may have difficulty saving the recorded videos.
Detailed instructions on setting up a backdrop and lighting for chromakeying and using the project interface to get optimal results. Also a link to a repository for downloading and printing protest posters to use to enhance your video performance

Note: This app does NOT record your voice, only your video

Just like in a real protest where your individual voice gets lost in the crowd. The app records your video with the protest video behind you and the chants from the protest video, preserving the aural atmosphere of the event.

Setting up a colored backdrop for chromakeying

Choose the largest, evenly colored item of fabric you have (like a single colored bed sheet). Even it if is a bit lumpy, like the seams in these panels which are velcro'd together, lighting it well and from multiple angles will hide any shadows or imperfections. The more saturated the color the better.
Avoid shiny fabrics that will reflect the lights.

For my set-up I'm using 4 very bright compact flourescent bulbs to light the backdrop, two high up and two near the floor.
I'm lighting myself with 3 soft boxes (also with CFLs inside) and using a ladder as a platform for my laptop.

I put black aluminum foil on the backs of the top lights so they don't shine my head. Light cannot go through the foil. The floor ones are fine as they can help backlight my body but are further from the camera frame.

You can use regular aluminum foil on lights that don't get too hot like these. If you need to do this with hot lights, use something to hold the foil away from the bulb so it doesn't get too hot and doesn't overheat the bulb and cause it to fail.

These are 600Watt photofloods. They get extraordinarily hot and will fail if you get fingerprints on the bulbs (so never touch them, when cold and of course don't touch anything when hot) or if shaken when hot they will blow. Be very careful with lights like this. These are similar to worklights (just calibrated for color), so you can use worklights. You need to soften the light by either bouncing the light off a bounce like above or bouncing off the ceiling or another wall. You can make your own bounce with aluminum foil taped to cardboard. Crumple the foil so it is not reflecting like a mirror, but is textured all over.
Direct light from these is nasty.
Alternatively you can create your own softbox. Here I took a fitted sheet and hung it. I put two weights in the bottom corners and put the photoflood about 5 feet behind it. See the difference: the photo on the left is behind the sheet: fairly good soft light with no shadows thrown. The one on the right is direct light and you can see it is very harsh with heavy shadows (look at the difference on my neck). Also my expression is different because I'm being blinded... and it is throwing my shadow on the backdrop messing up the chromakeying. Soft light is best for many reasons.
The ideal set up is to have a smooth, evenly colored backdrop that is separately and evenly lit. Use whatever diffusion you can to soften the lighting so you don't get hot spots and hit from as many angles as you can. I prefer to have lights in a row from above and from the floor.
Light yourself separately, preferably with soft, even lighting.

Make sure you are not wearing anything that is the same color as the backdrop or that item will become invisible on screen.

Practice before hitting record. You can record as many times as you like. Recorded files will be located in the same location as the app (so if the app is on your desktop, the recordings will appear there). I recommend you run the app from your desktop as other places may prove problematic (I know it won't work properly from your downloads folder).



Start by turning on your Webcam


shows five images of buttons with text on them, one for each video file in the project


Protest Video Buttons

Choose which video you would like to participate in by clicking one of the 5 buttons.

Each video is 1 minute long and loops forever.

You can keep one playing while you set up your chromakeying and adjust your lights etc.

Practice your performance and then hit record. Video will stop playing when recording is complete

Now it is time to work on chromakeying. Click on the colored backdrop in the place that seems the most average. Use the blue & white slider between the before and after screens to adjust the range of the chromakeying. You may need to go back and forth between choosing where to click and how much to adjust the range slider to get the best results.
You may also try adjusting your lights based on what you see. In the sample above you can see the background is unevenly lit so to include the darker parts in the key, it ends up removing part of the dark jacket. Best to fix the lights here before continuing.
Clicking in the wrong place gives strange results: here the video is playing in the sweater.
Slowly bring the range slider up
Adjust your lights as needed, and maybe try clicking in different areas when you get close to make fine adjustments with the three elements: lights, clicked area, range slider. 'Even if you cannot get it perfect, it may be ok to leave a little of the background color, as all gets desaturated in the final mix and the background video is contrasty and moving a lot, so better have some "noise" with you than some holes in yourself.
Go to far and you will have parts of yourself become transparent. Of course this can be interesting and you can get creative with this element.

With a clean, flat, evenly lit backdrop you can get good results.

Now you are ready to practice your performance and press RECORD.


After you press RECORD it will give you a 10 second countdown


Once recording starts it will give you a 60 second countdown before stopping and saving your file



After recording you can click on this pop-up and go back and start a new recording.

Please post recordings on social media.
