This is a test board, originally created to demonstrate how WebM video can be added to an imageboard.

Note: You can close an expanded video by dragging it to the left. When playing a video by hovering over the thumbnail (if enabled), you can use the scroll wheel to adjust the volume.

Don't post anything illegal here. Porn is okay, but please spoiler it.

ITT: ways of extracting clips from videos and editing them.

Here's a screen capture showing how to use ffmpeg and Avidemux to cut and crop a clip from a video. I've sped the action up by a factor of 2 so it's easier to watch.

I start by using converting the video into a format I know Avidemux can read. This isn't always necessary (and, in fact, wasn't in this case), but I wanted to show it anyway. To avoid having to convert the whole video, I start by opening it and finding the approximate time of the clip I want.

Then I invoke ffmpeg at the command prompt to convert the video:

ffmpeg -ss 20:40 -i source.mp4 -t 20 -pix_fmt yuv420p -c:v ffvhuff -an tmp1.mkv

To break this down:
> -ss 20:40
start at 20 minutes, 40 seconds
> -i source.mp4
input file is source.mp4
