FFMPEG supports a "video file name" of image-%04d.png, and moviepy accepts this in VideoFileClip() which is great. But unfortunately it assumes 25 fps, and I don't see any way to change that. I can call clip=clip.set_fps(24) but that doesn't change the duration - I think it just skips frames.

It would be great if VideoFileClip could accept an optional fps arg for this case.

This is a rather minor issue. Currently the source property of a transition (that is, the file name) can be edited. On pressing 'Enter' it reverts to the old file name.

It doesn't do any harm, but is confusing - and should not be editable I think.

But I guess very few people know that it's there anyway.

Add an option to specify the output blob format for Movie#record. Right now, it is hardcoded as video/webm.
