Export complete with your settings, thanks again for posting this. Plays fine in VLC but is choppy with Quicktime Player. Any idea why?

User Posted November 4, 2016 Share Posted November 4, 2016 Exporting a file from Premiere Pro using: H.264 2560x1440 Key Frame Distance: 1 Contrary to my post above, I'm getting choppy playback using VLC 10.2.4 but it plays fine with Quicktime Player 10.2. It also has choppy playback on Vimeo. Anyone know what the problem is? Key Frame Distance? Quote Link to comment Share on other sites More sharing options...

The only time when you want a key frame distance of 1 is when you want to use H.264 as an editing codec. Quote Link to comment Share on other sites More sharing options...

It was my understanding that if you have a lot of movement going in in your video you want a Key Frame Distance that is not so high, so I went with 1. I want to export a file that is 6:30 and I'm getting files that are about 3.5 gigs with the above settings. They look great on Vimeo, they just seem to stutter ever so slightly. What Key Frame Distance do you suggest? Quote Link to comment Share on other sites More sharing options...

What Key Frame Distance do you suggest? It really depends on a lot of things what would be the best setting, but if you want to be very conservative use a few frames. All intra (1 frame) would require a significantly higher bitrate. User 1 Quote Link to comment Share on other sites More sharing options...
User Posted November 7, 2016 Share Posted November 7, 2016 Thanks Cary. My export setting have been Export in 2560x1440p CBR at 90 mbps. Key Frame Distance: 1 I would think that VLC/ Quicktime should be able to play this back with stuttering. With my last export, I set the Key Frame Distance to 24 and it played back smoothly with Quicktime Player last night. However, when I played it back today it began to stutter. Now I'm starting to suspect this has something to do with my Macbook Pro... system memory etc? It's almost as if something somewhere is hogging the horsepower required to play it back smoothly. Could be that I had Premiere Pro open and somehow they are competing for resources. Anyone? Quote Link to comment Share on other sites More sharing options...
