Support cutting videos

[mat-mo]

Please add support for cutting videos, this can use the -ss option in ffmpeg.

I suggest using a forth checkbox that if checked will open a time range selection box. should be unchecked by default.

Mockup attached :

Hmm. why a dropdown? IMO they should support all integers.

I'm thinking of adding a third page on various parameters, for example video rotation. (Autocrop might be possible, but it's a two pass filter (one to detect border, one to actually crop & encode).

Just a mockup, i don't really care the exact UI :)

Unless the trim is designed to cut out copyrighted content, we are better off uploading originals with verified permissions to Commons before trimming down to sections. (For example, we import whole Flickr photos and recommend CropTool only after FlickrReviewer has verified the license.) This said, YES YES YES—this would be great. If you do implement, I'd suggest adding the timecodes to the description or source fields to make it easier for people to verify. (Maybe CropTool's maintainers can build this into their tool if you're too busy) danmichaelo/croptool#66

I support this request. I could help with the backend work if someone takes else can work on the front-end.

This would be very useful; for example for cutting out parts of a video to make clips from a video (there could even be a gadget with an "extract clip" button on videos) or for cutting out some non-CCBY parts of a video such as during an intro or a short part in between. Example of a video where I'd cut extract a clip of the cosmic calendar part for a shorter video about the subject for the subject page where I'd embed this part and only link to the full video. It would be best if at some point it could show the frame of the first and last part of the video so one can dynamically adjust.
