P: Glitchy Video in Timeline

Here is an example of the digital artifacts I'm seeing in Premiere. This was a frame export. Renders do the same thing.

We are a production company, running Premiere Pro 24.5 on Windows Machines.

Since the update to Premiere Pro 24 (or so, the Update that brought the New Timeline Design), the Decoder/Encoder for XACV-L (which is our main acquisition format from Sony FX9/FS7, as is for many production companies that use Sony Cameras) seems to be broken. Other people from the industry have reported that it happens to XACV-I Footage from the Sony FX6 Cameras as well.

Viewing the footage natively is not possible. It constantly drops frames and Premiere gets incredibly slow, until it just shows blackscreen instead of the footage. It shows a red message in the corner that it could not retrieve the frame, and after a number of attempts it just gives up.

Trying to export the footage from Premiere just freezes the program; adding to Media Encoder Queue and rendering does work, however, horrible glitches get exported with the footage. I have added a few screenshots on how it looks.

The only way around it, as for now, is to transcode the sourcefile to some intermediate codec in media encoder first, then replace the XACV footage in the project manually. This takes time and a boatload of storage when you are shooting long clips.

Needless to say, this is a bad issue; we have a hard time trusting our exports and have to watch everything 3 times before it goes out. We tried different hardware configurations, Software only rendering, etc. and since we are not the only ones affected, i would assume this is an issue that came with the update. It is so bad that I started to see these kind of glitches all over TV now. People in the industry here in Austria have reported that they are considering switching to Media Composer again because all of their acquistion happens on Sony cameras whose footage experiences this kind of problem.

I just wanted to draw some attention to this issue and get feedback if other users are experiencing this as well; and if anybody has found a way around it yet. (other than waiting for Adobe to fix the issue).

Thanks, Jamie. 

Hi @eegriff - We have received the files and I can confirm the problems you are experiencing.  In the meantime while we investigate further for a solution, a simple workaround is to go to your Settings > Media > and at the bottom there is a checkbox labeled "Enable Hardware Accelerated Decoding" make sure this box is unchecked then close Premiere Pro and relaunch this should clear the glitches.  Thank you for your help investigating and troubleshooting. 

HI @eegriff - would you be able to send us one of the files so that we can take a look?  You can send a link to jamiec@adobe.com It would also help if you could do a screen capture so that we can see what you are experiencing.

I downloaded the Preimer Pro beta, launched with Shift, selected all four radio buttons (clear cache, etc.), loaded a recent MXF clip, and... the video glitch is still there.

Hi @eegriff - This is done after you have updated Premiere Pro.  Launch Premiere Pro while holding down the "SHIFT" button on your keyboard.  A dialog box will open with options to select.  Most important ones would be "clear media cache", "Reset plugin loading cache", "Disable third-party plugins"

Tell me more about "remember to hold down shift after any installation". When exactly do I do that? 

[waiting to see the results of Jamie's suggested steps]

We recently made some updates in the beta version 24.6 when working with MXF files.  Please open the creative cloud desktop app under the beta apps in the side bar and try downloading Premiere Pro 24.6 beta.  Alwasys remember to hold down shift after any installation and check the boxes to clear media chache, reset plugin cache and if you have any problems you can test by disabling third party plugins to troubleshoot.  Let us know how it goes.
