All I know is I have had plenty of experience with h.264 choppy and sluggish timeline performance to know I never want it again, and I spend too much time on this forum and see people with export errors all the time, and their screenshot or text explaining the error is ALWAYS h.264 related. I mean, sure people seem to power through those aspects and make it work I guess, and fine have at it. The settings are more limited, it differs between what AMD and NVIDIA really do, and has reliability and quality issues.Įase, smoothness, reliable are not ever aspects known to h.264 and NLEs.h.264 is slow, choppy, and complex. GPU accelerated encoding for h.264 is relatively new for premiere, like less than a year.and while somewhat neat, I have also seen plenty of users here have many issues with it. I shot a video with the Canon 5 d Mark III (1080 p) and edited a 4 minute video that I. Not to mention how much easier and smoother DNx clips are to edit and scrub through thus making my time actually reviewing clips and making a sequence faster than long GOP interframe trash like h.264. Whereas similar 5 min videos of all h.264 clips exported to h.264 was easily a 14-20 minute wait. And a transcode to h.264 took 2 more mins tops. I’ve literally taken a 5 min long edit using DNx encoded clips along with some simple motion graphics from after effects, exported to DNx, and it took 20-30 seconds to export. Optimizing media (or better yet, recording to optimized media in the first place) and exporting to the same saves time. I have no idea where you come up with this number nor why you think that’s what I’m advocating.
