Here is a couple more video editors that you may want to look into. |
63 |
|
64 |
Kdenlive kde-apps/kdenlive |
65 |
|
66 |
Avidemux media-video/avidemux |
67 |
|
68 |
The first one is KDE based. Last time I used it, it was large but had |
69 |
lots of fancy stuff it could do. The second one has both a gtk and qt |
70 |
based version. I'm guessing that is controlled by USE flags. I seem to |
71 |
have both of them here. :/ |
72 |
|
73 |
Maybe one of those will help. |
