Choppy ProRes 422 HQ playback
Please…
I converted files from R3D to ProRes422HQ and they played well in VLC and also in the QuickTime Player but when I imported them into Premiere CS4 (OSX LION) they stutter as if frames were being skipped. I tried various project settings and interpret settings but nothing seems to work. Also the aspect ratio appears right on the source window but very oversized on the timeline viewer.
BTW other kinds of files (MP4, MOV) played well. But not these 422HQs.
Unfortunately I can’t reach the DP for specs on how he shot it so I can only go by the specs Premiere gives me (24 fps 2048×1080) and trial and error, but I can’t seem to get it right.Can anyone out there please help me?

If the computer were the problem, why would the clip play so well on both VLC and QT Player?
I’ve also tried lighter codecs and different settings, but all I could attain was a smooth source window playback at normal speed yet with diagonal line artefacts that don’t go away with the anti flicker.
What’s really strange to me, and which might give a clue to the problem, is that every codec and setting I tried always produces a giant oversized playback on the timeline, though it always fit fine on the source monitor.
Can anyone please advise me?

Premiere is more than just a video player and requires more resources. Unfortunately it’s hard to pinpoint the problem without any info on the computer.

Please tell me what info you need and I’ll try to provide it. I never had this problem before with other codecs and other clips play fine but this one stutters no matter what codec I use (I haven’t tryed all of them) like maybe there’s a problem generating a preview file or something (obviously I’m no expert).

un-ticked “Enable accelerated Intel h.264 decoding” in preferences/media tab and closed extra premiere panels-hidden

Thanks but I’m on CS4 and I don’t have any audio on the clip. The clip is 2048×1080 (1.0) at 23.98 fps. It’s like it can’t handle HD.

PLEASE TELL ME WHICH CODECS I SHOULD TRY for Pro Res 422HQ NTSC 2048 x 1080 (1.0) 24p (on CS4 on LION). THANK YOU VERY MUCH!

I have similar problems…. files play great in Quicktime Player, Quicktime Pro 7 and VLC… Premiere 13.0.3 they ripple weirdly over any straight borders or straight lines.
I have Mac Pro, 64GB of RAM, 8GB VRAM and 12-core processor

PS I can play 4K RED files right out of the camera, no problem, but I had some drone footage that was H.264, used Media Encoder to transcode to ProRes 422 HQ, and those files play great everywhere but Premiere.
