MXF playback is not smooth - advice
on Apr 24, 2017 at 9:24:11 pm

I have received 1920x1080 footage from my client shot on a C300 Mark II. It is MXF (AVC-intra). To work with it on previous projects I had to transcode to ProRes, otherwise I could not get it to play in sync with audio, or playback would be choppy. I certainly couldn't do any multicam edits.

My client now wants me to take a project over from someone else who has worked with the client's footage natively in MXF. Can anyone help me understand why I can't get it to play smoothly? I will need to get it to do so to take on this next project that has to be done in MXF.

I have 24GB RAM on a Mac 4,1 quad core 2.26 cheese grater with a nVideo GeForce 770 (macvidcards flashed) running the most recent driver and CUDA driver on Premiere Pro CC2017.

On what kind of device will the mxf footage be stored?

Media is on an internal RAID. And previews are on the SSD.

That is a really old system. I doubt it will allow for GPU acceleration. Having sad that did you try playback at 1/2 resolution?

Doesn't matter if it's full, half or quarter
