This morning I tried capturing a video using matinee in 4.11 and found a big green bar taking up the bottom half of the video. Made a really short example video: Dropbox - File Deleted
I tried a PNG Sequence instead and that came out as expected, so it must be something with the video capture.
I just tried this on my end and was unable to reproduce the green bar. The video you sent does not have a green bar (played with both Windows Media Player and VLC). Also, was your video supposed to be only two frames long?
Can you send a screenshot of your movie capture settings?
I tried it in VLC instead and it looked normal, so maybe it’s a codec issue or something. And I did mean to make it really short just so it was a small download size (I originally tried to attach it directly but apparently the answerhub doesn’t want people attaching AVIs).
If it’s just a codec issue then this probably doesn’t matter, but here are my settings just in case
