Hello
The program is good but:
I edit many mp4. h264 videos every day and the mainproblem is to find the right places to set the markers quickly. It costs too much time. The function to navigate to next keyframe is good, but by far not all cam/scene changes (cuts) are on keyframes. It depends on the video. So the only thing I can do is to use the picture mode, but to switch in it takes too long. (I have a fast systerm) Or take the arrow keys to find them. Imagine you want to cut out 20-50 scenes per video, it takes too long. Adobe Speedgrade has such a scene change detection in it. I would be very glad, if you could implement such a tool in the video splitter.
Furthermore for better overview it would be fine when the timeline (thumbs) could not be only one line. If it would have two or more (adjustable), more thumbs could be loaded in advance. At the end of the line I have to wait for the next thumbs. It depends on the video how fast they load. Next thumbs should be loaded bevore the cursor is on its end.
In the navigation please implement adjustable jumps in frames like 2,5,10 frames.
best regards
