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.

Describe the new feature:
The openshot_qt file contains to much personal information.
So one has to anomize it before submitting it, a lot of work

Describe the solution you'd like:
Openshot should anomize all filenames and (sub)foldernames in the qt log file, because they can contain personal info. I believe this is a GDPR issue.

Describe the bug:
The "Pixelization" values is not linear. It starts with 0,0 which means "no pixelization at all", through 0,9" which means "heavy pixelization", but ends with "1,0" which does not pixelate at all (i. e. 0,0 and 1,0 behave the same). This makes it hard to understand for the user, and hard to prevent failures in usage.

Steps to reproduce the behavior:

1. Use Pixe

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