AS-11 file fails AQC due to incorrect Coding Equation

Exporting an AS-11 from Premiere Pro v23.0

When testing with the AQC from Telestream (Qualify) it reports the following error:

Found 1 structural problem(s) with AS-11 UK DPP conformance: - Picture Essence Descriptor item 'Coding Equations' must be [060e2b34.04010101.04010101.02020000] (when present) but was [060e2b34.0401010d.04010101.02020000]

The second part of the descriptor is not what it should be. This is, I am told, an issue in the exporter from both PPro and MEnc and reported since at least 2019. It is embedded in the .mxf and cannot be edited externally. As this is a key element of getting programmes to broadcast it is essential that this gets fixed to live up to the 'Pro' part of Premiere's name.

Hello @Mr Seaniepie, @rynprc, and @Chelsea27503698q32v,

Thanks for the messages, everyone. The team says the bug is with VidChecker for ACQ.

Unfortunately, Vidchecker isn't correctly identifying the UID; the color equation settings are showing as unknown instead of 709.
The PDF of the tool's output shows that Premiere Pro has the codingEquation set to CodingEquations = [060e2b34.0401.010d.04010101.02020000],
VidChecker shows that the 8th value in the UID should be 0x01 instead of 0x0D.
The SMPTE ST-400 doc states that the 8th byte represents a version number.
VidChecker is expecting a hardcoded value of 0x01, which is incorrect.

I hope that explains the anomaly. Please let me know if there's anything else I can do to assist with this problem. Thank you so much for your patience in receiving a response. Please take care!

I will move the post back to Discussions.

Thanks,

Kevin

I'm having this issue also - I'm not sure if it's really Vidcheckers fault as the 'Color Space' from Adobe AS-11 files are showing as 'Unknown' in other metadata apps....

It comes up as 'unknown' only because these other metadata apps have not hardcoded Adobes preset [060e2b34.0401.010d.04010101.02020000] into their software as being from Adobe. Perhaps you could send this to those developers too along with a link to this thread so they can make the necessary adjustments.

It's not really up to us the users to make Adobe applications compatible with industry standard software. Adobe should be testing it against software like Vidchecker when they're making an DPP export preset. It's next to useless if Vidchecker won't accept it when it accepts Avid AS-11 files.

That's incredible! Fantastic work Kevin on working this out. I will make sure that the great people at VidChecker are made aware of this anomaly and I'm positive they will make the necessary changes.
All the very best.

Hello @Mr Seaniepie,

Thanks for the message. It’s been a long time since you filed this bug, and I apologize for the lack of a response. Are you still having this issue? If so, the team will need more information from you to reproduce the bug. Can you provide the information required here? How do I write a bug report?

I'll move your post to the Discussions board while we await your information.

Thanks, 

Kevin

This seems to still be happening. Moved this to the Bugs section of the forum.

For what it's worth, & Adobe should fix this regardless, it can be externally edited. Either by running the file through the out of support DPP app (very slow) or using AMCDX to change the tag information in the header (very fast).

Pretty farcial that this is still happening though.

Hi @rynprc,

I have asked the team if they are working on this issue. If not, I'll file your bug internally. Let's move this post back to the Bugs forum, then.

Thanks,

@Bruce Bullis or @Fergus H would be the people to check with on this.

Do Adobe look at these for bug reports?

Bugs are still technically filed on their Premiere Pro UserVoice system. Though they are migrating over to here at some point apparently. They've done so with a couple other apps.
