Varicam 100fps clips rendering/display problem

[Studio Zandman]

Premiere Pro 23.0.0 (Build 63) has a problem displaying Varicam 100fps clips. It resizes the image to 50% vertical size and the rest of the image is green.

I previously posted to the Adobe Media Encoder bugs forum because I thought it was an AME problem when making proxies, but it seems the origin of the problem lies in the way the original MXF clips are rendered by Premiere Pro an Media Encoder to begin with.

The other (15fps and 50fps) MXF clips are rendered/displayed correctly.

The previous version of Premiere Pro and AME (22.6) don't have this bug.

Instead of 15fps I meant to write 25fps...

It would be convenient if I could edit the original post....

Thanks for the info. Can you please share with us some sample files? 

Thanks,

Hi Fergus,

I assume you want me to share a 100fps mxf Varicam clip? How can I do that? The "insert video" option does not let me add a clip from disk...

Best, Harald

I see somewhere that a reply is supposed to have an attachment box under the text box. It doesn't show up in Safari or Chrome, so maybe there is an e-mailaddress I can send the sample files to?

Also: attachments in this forum are limited to 40-odd Mb, the sample files you would need are mostly more than 1 Gb...

Hi,

Can you give us the system specs? Mac or PC? Which GPU? If NVIDIA, what is the driver version? If later than 522. xx, do a clean reinstallation of the earlier driver. Many have rolled back to 517. xx. I hope this added info helps.

Thanks,
Kevin

Hi Kevin,

I'm on a Mac Studio (2022) M1 Ultra, 64 GB RAM. MacOS is Monterey 12.6.1 and I'm using Premiere Pro version 23.00 (Build 63). I'm assuming this also answers your question about the GPU?

I'm happy to provide example clips, but since the files are pretty big I would need an address to send them to. I see no way to attach them to this post.

Hope this helps, please feel free to contact me for any assistance I can provide.

Hi Fergus,

I haven't heard from you about a practical way to share sample clips. Please let me know how I can be of help. Attaching clips to this post seems impossible because of file sizes...

We have the same issue with our varicam footage for all mac M1 workstations in our post house. I nailed it down to footage which has a different rec time base than recorded. For us 4k 50p on a 25p timebase. This bug is driving us nuts here. The only workaround rn is to scale the footage vertically by 200% (horizontal stays at 100%) and reframe the picture. 

We had that same issue in 22.4 (I think), so we used 22.3.3.1 for most of the time in all Version for 23.x this bug is appearing.

We're also having this exact issue. Varicam footage (25fps 4K) plays in Premiere exactly as your image (squashed at top, green at bottom). Mac Studio M1.

Joseph28962788ypph, 

Would it be possible for you to share a sample file with me? Let me know via private message if you need a share location and I can send one to you. 

Regards,

Fergus

@Fergus Hhere is a folder with one of the Varicam LT clips and some screenshots of how it looks when we bring it into Premiere v23.2.0. The workaround is to stretch the frame on the timeline is not great. https://we.tl/t-mdVeNaXhTH
