Digitizing football games from VHS tapes to .mp4 files. Seeking editing software to delete commercials, halftime and scoreboard shows, etc., that will then simply save the file, when edits are completed, in its original quality and Mbps. iMovie requires selections for Quality (low, medium, high, best or custom) when exporting the file. Selection of Custom requires determining Mbps with slider. Final file size seems to always be larger than the original pared down file no matter what Quality selection is made. Have minimal experience with iMovie, so perhaps it can do what I'm asking. If not, is there a simple editing software to just cut and save video files? Thanks for your advice.
