To use Streamclip to trim a file, follow these steps:
Open the .mp4 file to be trimmed
Drag the slider to the starting sequence of your new clip
and select the “In” point where the new clip should start
Align the “In” point to the nearest key frame. This is
required to eliminate pixelation and picture breakup at the
start of the new clip. If that key frame is unacceptable as
a starting point, move the slider backward or forward until
a usable key frame is found.
