Detailed review on a great Mac video processing utility from Jeffrey:
Everyone who works on video beyond schoolkids knows the value of editing, file conversions, resizing videos, and the kind of hardware you need to do the job right. VideoProc is a single video and audio conversion utility, hardware-accelerated for speed, and packed with tools that go beyond the basics of cut and include segment merge, subtitles, crops, effects, and all the extras you need to make your YouTube presence obvious.
Tried it. Liked it.
VideoProc is a worthy utility to consider; priced right, free trial, subscription at the base level, but an inexpensive purchase option.
