If all you need to do is quickly convert an entire video file, this app does it well. If you want to ‘trim’ a portion from a video — it lacks basic functionality.
Once you click the [TRIM] button there’s another [Add Trim Marker] button. Then you can drag the trim slider start and ending positions, or type them in the Start/End fields. I’d previously used a similar Windows product, Nero Recode. With Recode, once you click [TRIM], left and right marker buttons appear to the left and right of the video’s timeline slider, you move to where you want the clip to start, then click the left-trim, then where you want it to end, click the right-trim, and export. For some reason the $60 VC-Ultimate app doesn’t have start/end buttons to click based on position. To make matters worse, once you’ve gotten the positions exactly where you want them and then you export the clip — the start position is >never< what you were looking at within the app when you defined it — the exported video begins a little before what you wanted. Very frustrating :-(
Also, theres a main Preferences option to edit without volume — but no volume control within the app while you’re editing. Considering the limitations of basic functionality, the app is overpriced. $5-$10 would be more appropriate.
