Trim Modes Explained
Fast mode (stream copy): Uses ffmpeg's `-c copy` which doesn't re-encode the video. It's very fast but trim points snap to the nearest keyframe, so exact-frame precision isn't guaranteed.
Precise mode (re-encode): Fully re-encodes the selected portion. Frame-accurate but slower since it processes every frame. Best for exact cuts.
