Hi, Is there a sane way to perform, with the various yuv4mpegpipe-based tools, something comparable to the keyframe-based automation found in graphical video editors such as Cinelerra?
The only (insane) way I can think of is to: - determine start and end points (keyframes) of automated transition - determine a function which interpolates settings between these keyframes - break up the set of frames into short sequences, for which the settings are the same - for each subset of frames, run the required piped tools with the interpolated setting values Example - given PAL 25fps video, start at normal zoom, then increase to 2x zoom between frame 100 and frame 200. This would require running a yuv4mpegpipe zoom tool such as y4mscaler on one frame at a time, each frame with different options passed to y4mscaler. I'm worried that if I do this, the cost of having a tool like y4mscaler starting and stopping one per frame, with different options each time, will get totally ridiculous. So is something like keyframe-based automation a totally crazy idea for yuv4mpegpipe-based pipe tools? Or is there a better way than what I've discussed.
