I’m having trouble compressing a video (NTSC, .dv format) without getting blockiness in the red area. The .dv file does not have it, but when compressing for playback on a Brightsign player, every file I make has this blockiness. I’ve tried H.264, and both HD and SD MPEG-2 Transport Streams. (screenshot attached)
Any suggestions for file formats that wouldn’t have this problem, or maybe I just need to change a setting in Compressor? I could also use Sorensen Squeeze 6 if it would help.
Currently I’m just doing trial and error, but I’m running out of time, so any advice is appreciated.
That red shirt is probably too saturated. Use the LIMIT EFFECT option in the 3-Way Color Corrector to select the red shirt and desaturate slightly.
Correct to legal standards then compress as ya need.
