It may have to do with your media color space.

Worth a try: Context-click a problem clip in the bin and choose Modify>Interpret Footage. Check the color management section to see if all is well. If you are using bog-standard HD footage, you may need to override the color space to rec 709.

Hi Jeff,

 

Thanks for the note. Unfortunately can't seem to fix it thast way.

 

It's very strange, i imported into Resolve and it's all perfect. Perhaps time to switch ?!?

I exported the file and it seems fine. So the original file is fine, it has visible artefacts when imported into premiere but once exported out seems fine once again.

I'm glad the export went well!

 

What format and codec is your source footage, and what are your sequence and export settings? 

My thinking is that maybe Pr misinterpreted your footage on import, but that bad interpretation was canceled out by your sequence or export settings or both.

Hi,

 

Source footage is 1080HD Pro Ress 422 HQ 10bit XAVCi.

 

Sequence is custom ProRes422 24p.

 

On export i usually do what looks best and so it varies. 

 

Not too sure about the interpretatioon from Pr as this is showing up in both the source monitor and on the sequence. It feels like Pr is not viewing/displaying it properly ?

 

Problem being i don't know what is not displaying correctly or what is incorrect until export. And perhaps more importantly Pr should be able to show the footage properly.

Yes, Pr should be able to show the footage properly.

That said, we should investigate why it's not.

So that we're all on the same page, please post screenshots of:

  • The Clip>Modify>Interpret Footage dialog for one of your XAVC-I clips
  • Your sequence settings

There may be clue(s) there.

That is the info I asked for, but it is not what I expected to see.

What version of Pr are you using, please? And on what platform?

Thanks!

you said "set on full". i'm guessing you mean resolution or playback settings?  also, there's a separate setting for paused playback under high quality setting.

 

does the issue appear when you're playing back or just when you're paused?

 

 

also i'm curious if you export into a cineform and re-import, if it still appears. at least that would narrow down if its a codec issue or something else.

 

maybe a pre-multipled problem in the alpha channel?

what happens when you change the video preview codec type?

Hi,

 

It appears both paused and in playback.

 

I don't think it's a codec issue as the files are recorded straight into ProRes 422HQ  on a Video Devices recorder and so are as unadultarated as can be. Also they look fine in Resolve etc....

10-bit XAVC footage would have been bleeding edge for CS6; I'm pleasantly surprised it handles it at all!
My recommendation is to try your footage in the new version of Pr.

It's not 10 bit XAVC, it's Pro Res 422HQ recordedd straight into a recorder. The footage works on final cut pro 7 (pre CS6) and Resolve no problem at all. The fact that CS6 is sopposedly 'doing well' to mess up a pro res file is a bit Adobe centric if you don't me saying. Parasite (Oscar winner) was cut on final cut 7 with much heavier codecs than what i'm using and they had no issues. I know dozens of award winning filmmakers cutting on FCP7.

 

I guess it's time to follow the herd and get in bed with Resolve 18. No way on earth i'm paying subscription fee's to Adobe when Resolve 18 is basically taken Premiere to school.

 

I find the notion that CS6 cannot playback a pure a pro res file just a little bit off the edge of reasonable.

Apparently I misunderstood. And you are correct that CS6 should be able to play back pure ProRes files on a Mac. But that's not the assumption I was working under. Apologies if I got it wrong. 

 

And it's highly likely that a recent version of Resolve may perform better than an old CS6 version of Pr. Within the limits of your time and budget, you should at least try the latest version of Pr before you abandon it completely. If you've already done that or just don't want to, then I hope Resolve or FCPX or something else does the job for you.

Si basically back to square one. I have a prores material that in the past has worked in an NLE designed for it that can't be played back or viewed properly without displaying artefacts that the NLE itself causes.

 

And no one can figure out the reason why ?

 

People have been playing ProRes in Adobe products for decades but alas this issues seems to have escaped the community.

 

Leanardo, where are you ??

Is it just these files that show the problem? Or does *all* of your media do it?

 

If this just started, and it seems from what you've said that it has only recently begun, then changes to your system or changes to your typical source footage are to blame. CS6 hasn't been touched in almost a decade and is well past EOL.
