C70 XFAVC .MXF Flicker in Premiere

Community Beginner ,
Jul 22, 2022 Jul 22, 2022

Copied

There appears to be a software bug that has been recently introduced that causes .MXF footage to flicker in the Source monitor, Timeline playback, and in even in the exported file. It seems to be an issue related only to MXF files coming from the C70.

It almost seems like it's enabling/disabling a lumetri color effect even when no effect is applied and is very random across clips with the only constant appearling to be that the affected clips are all .MXF files. Any other codecs are unaffected. Project files older than a week or two ago seem to have no issues.

I will be transcoding all raw footage into ProRes upon ingest untill this issue is resolved.  

 

See attached video files as an example.

I also had flickering/strobe issues with .MXF files out of a Sony Fx6. Spefically, cinetone footage was flickering but Slog3 footage was fine. Rolling back to 22.4 fixed my issues as well, thanks for posting!

I have been having this issue as well, but before I join the dark side (da vinci resolve) how do I roll back to 22.4. This is really an awful bug that makes depending on premiere a gamble. Thank you.

@ghostframes I messed up posting the screengrabs, but start with your Creative Cloud Desktop App (the bottom screenshot), go to Premeire Pro, select the three dots on the far right to bring up the dropdown menu. Select Other Versions and that will bring up the menu to select what version of Premiere you want to install (top screenshot).

 

Hope that helps

Try rolling your version of PP back to 22.4 and see if that solves your issue. Been working well for me and my editor for over two weeks now. Zero flicker.

Same exact issue for me with S-Cinetone, MXF footage from a Sony FX6. My rig is an Intel i9 1200K, 64GB RAM, 3080ti, Windows 11. Got a call from a former colleague this morning and he is also having the same issue with footage from FX6. I am going to roll back to 22.4 as suggested by others and will report what happens... already done and it did solve it.

Adobe, you do try to be a video editing platform, right? Why would you not test updates with current codecs before you release? DaVinci is looking better and better.

Today's Update fixed it. Unfortunately, I was struggling for 2 hours made sensless transcodings and had lead conversations with the camera operator about that. Such Talks raise the monthly fee for that subscription. Adobe, please take more care of your customers if you want to be professional, before you meet the same impact as on the stock ;-). It's paid!

Hi Andrew.

 

2 things I would very much like to run past you, if you don't mind?

Firstly, would this maybe account for a new 'flickering' almost as if a frame is getting dropped at regular intervals - when I run a frame rate conversion process from 25fps to 24fps (it also triggers if I sue 23.976fps) that in the past always used to  give me flicker free output?

Secondly - using ProRes may not work on PC, as ProRes on PC seems to get wrapped as MXF. Maybe I should try a MOV wrapper?

Any thoughts would be wonderful.

two solutions for this that I've used successfully:  select clips in bin/project, right click and choose modify: interpret footage and choose color management and if the media color space is anything other then rec 709, enable color space over ride and set to rec 709.     This not only fixed this issue with the camera original, it also fixed the issue with already created proxies...  I think Kevin Monahan suggested this (but don't really remember)

 

And if that doesn't work (which has happened once or twice) change the file extension from .mxf to .mpg. This was suggested by Ann Bens..

Changing to .mpg fixed it (for now. I'm confident Adobe will find some way to break this workaround in the future).

 

Thanks!!

Do you think adobe is doing this on purpose?  I understand your frustration, but formats are constantly changing, the way cameras handle media is constantly changing...  computer hardware is constantly changing...   When I have a problem, I post the issue here and I usually get a solution...

I have had this problem in the last 2 of a recurring edit (I think the camera guy upgraded his Sony to a new CANON, EOS C70).

 

During last month's edit, I noticed I didn't have the issue when there was a text layer over the footage, so I put a text layer with spaces (so it appeared empty) on the top track and that fixed it.

 

Sadly, my fix isn't working this time. I'm running:

Mac Pro (2019)

3.3 GHz 12-Core Intel Xeon W

256 GB 2933 MHz DDR4

AMD Radeon Pro Vega II 32 GB

OS Monterey 12.3.1

Premiere 22.5

 

My assistant editor is running the same version of Premiere on a Mac Studio with no issues.

 

Looking at your sample, I'm dealing with the same issue. Looks like a LUT or Lumetri being toggled on and off at random.

 

I so love paying to beta test adobe products. It's so much better than getting a fully tested and ready for Prime Time version once every year or two. Yep. Totes my fave. 😕

Might help some of the people experiencing the issue if you told us whether you're on a mac or windows...   I did see less problems on a windows machine when I updated to 23.0.    Unfortunatley, my mac's too old to update....
