I'm transcoding 5k prores footage from the 5k epic shoot yesterday. My mac station is very well equipped. Its a 12 core, nvidia, speced out in ram, one red rocket card box. I am having difficulty transcoding this one long clip. Its about an hour long of a clip. It keeps getting to 99% and then stays there for a long time. I don't know if I should quit out or hope for it to run its course. Its been about a half hour now and its still at 99%. The program hasn't stopped responding. Its still moving, but not finishing this clip. Any suggestions?
