Creating a 3D presentation with ffmpeg

Question

linux

There is a video clip of a certain length with an alpha channel. There are images of different resolutions. You need to insert images one by one into the alpha channel of the video. But there is one caveat: the alpha channel appears either on the right or on the left. Is it possible to determine the coordinates of inserting images into the alpha channel of a video file? Is it possible to determine the rotation coordinates of an image in 3D space along with the alpha channel? We are only interested in ways to automatically create such a video, maybe not ffmpeg, but other similar software. Ideally a script. Thank you.

Answer 1

You need Adobe Premier, not ffmpeg.
FFMpeg is a transcoder with the ability to use filters, but all of its filters are quite primitive and mainly concern only the quality of the video and the ease of its perception.

Answer 2

You need to extract the alpha channel, convert it to monochrome, use the program to determine the boundaries of the transparent (and rectangular!) area in each frame, and match the change of coordinates with the frame number / time. On what thread like PHP+ImageMagick it can be done. After that, create a video from the photos in accordance with these data. With this (in theory) ffmpeg itself will cope, it will need to substitute the appropriate parameters in the command line. I'm afraid to imagine its length =)

Answer 3

Can ffmpegy set image coordinates frame by frame (i.e. 1 frame - one position, 2nd frame - the next position)?
