A transparent GIF (Graphics Interchange Format) is an image file that has one color assigned to be "transparent" so that the assigned color will be replaced by the browser's background color, whatever it may be.
Open the image editor and select “Wizards” then “Transparency” from the top. Then you can click on the background color that needs to be removed. It will then convert the animation into a transparent GIF automatically.
The GIF and PNG formats also both support transparency. If you need any level of transparency in your image, you must use either a GIF or a PNG. GIF images (and also PNG) support 1-color transparency. This basically means that you can save your image with a transparent background.
With Kapwing's smart background removal tool, you can isolate people from the background of a video for free, without a green screen. All it takes is a few clicks. Open the Kapwing Studio and upload your own video, or use one you found on the web.
Just putting it here kinda as a tl;dr: to use MOV with transparency, one option is to use codec Apple QuickTime Animation ( qtrle in FFmpeg) and pixel format as argb or something like that.
Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs.
The file types that currently support an Alpha (transparency) channel are FLV, F4V, AVI, Quicktime, and WebM. If you're using free programs, you may find they can export in these formats. Often, there will be a named codec for an Alpha channel within the settings of these, or a PNG option.
Older (6 and prior) versions of QuickTime Pro had a "color picker" that could set a single color as the "transparency". It's missing in version 7. Version 7 does allow transparency but it is had to add it into a file that wasn't prepared to be transparent.
You can use animated PNGs. Show activity on this post. Try Huffyuv. It is a lossless codec that might work well with the kind of video you are talking about.
png, stands for Portable Network Graphics. It is a type of image format that web designers use to create websites because it supports transparent backgrounds and/or semi-transparent images (it is, in fact, the only type of image format that supports transparency).
Double-click the picture, and when Picture Tools appears, click Picture Tools Format > Color. Click Set Transparent Color, and when the pointer changes, click the color you want to make transparent.

It is one of the best apps to change video background without green screen!
Tap the More button , then tap Green/Blue Screen. The green-screen clip is added to the timeline above the background clip. In the viewer, tap Auto to automatically remove the green or blue from the clip. Or tap the color in the clip in the viewer to remove that color.
The best way I know is to test if the alpha channel has a mean=0. A fully transparent image has an alpha channel that is totally black.
So, what is a gif? Gif stands for 'Graphics Interchange Format' and essentially, it's a looping animation/ video consisting of a sequence of pictures or 'frames' if you want to get technical.
