MXF OP1A XDCAM MPEG 2 Export Issues on Windows

PostTue Jul 30, 2019 2:02 am

Hi,

On the Windows version of beta 7, I'm having rendering issues with a particular part of a program opener when exporting to MXF for broadcast, in particular XDCAM MPEG2. I've tried DNxHD and the problem doesn't happen. It also doesn't happen on macOS with XDCAM MPEG2.

It doesn't matter what source footage I have, or what codec it is, but whenever a particular animation happens in the opener, it glitches exactly the same way when exporting to XDCAM MPEG2. Attached are a couple of screen shots.

If necessary, I can share the opener clip if that will help with diagnosing the problem.

Try different player- MPC-HC, VLC, Switch from Telestream. It may be playback issue.
Import file back to Resolve- does it show the problem there also?

I've tried different players, even playing the same file on a Mac, and the issue is not the player. The artefacts are baked into the video.

Sorry, forgot about that. Here is the info:

CPU: AMD Ryzen 7 3700X
GPU: NVidia RTX 2070 8GB
RAM: 32GB DDR4 3200MHz
OS: Windows 10 1903 Build 18362.239
DaVinci Resolve version 16.0.0.050

The animation isn't in Fusion. It is an After Effects render in ProRes 422, but it even happens when exporting an edit of a live mix from our control room that contains that animation, or when I bring in an H.264 version of it. That suggests to me it's not the source file causing the issue either, but rather the way it's being rendered out from DaVinci Resolve.

Hi,
I have the same issue and i think this bug started with Resolve 16.
When exporting in MXF OP1A XDCAM MPEG 2 random parts of video get corrupted and there is a strange quality loss in subtitles.
Other codecs are fine. This issue only occurs when exporting in MXF OP1a format with XDCAM MPEG2 codec.

What are your computer specs? Are you using Windows too? I don't seem to have this problem on macOS, just Windows.

Not a solution, but might help you get the work done.

Export to DNx and then encode that export to XDCAM.

This problem has not been resolved in 16.1 beta 1. With another of our series, it happens in our stinger transitions, and during our credit roll.

Exporting in another format first and then using something else to create the MPEG2 MXF will be fine for us for now, though it delays us getting programs to air. But for other people, some broadcasters require no more than a second generation from the recording and doing that will add a third generation, which isn't suitable.

We've tried this solution but we keep having the same issue on the exported MXF OP1A XDCAM from a DNxHD 10bit.

Using: Resolve 16 on Windows pro 10 (NVIDIA GeForce GTX)

Apparently version 16 introduced this bug. We are going to downgrade to 15.3.1 and test again.

We have reinstalled Resolve 15.3.1 on Windows 10 pro in order to test XDCAM export again and I can confirm it does not create glitches.
We look forward to have this issue solved in version 16.

I've noticed the same issue on windows trying to export MXF OP1A XDCAM MPEG2 interlaced. I've got the same artefacts on pictures containing fast motion. No issue when exporting progressive. And no issue when rendering from a Mac opening the same project on a shared database.
It seems to be a bug.

Hello everyone,

I've got the same bug using the brand new release of Resolve 16.1 downloaded this day.
I confirm everything you've said about it. It works correctly with Resolve 15.
Anybody knows if there will be a patch or something for this bug ?

Thanks,

Max

I have just tested with new 16.1....
The issue is still here!

Every fast motion and full white images create glitches on windows! No issues on MACOS

In attachment an example.

I hope that someone in Blackmagic is still reading this post. I contacted the technical support and they told me that they can't reproduce the error! It's very Simple I can reproduce it any time I export in XDCAM! :lol: :lol: :lol: :lol:

Hope they solve soon!

As far as I remember MXF OP1A XDCAM MPEG 2 is only in HD 1920x1080 (although the format of the TL is 2K DCI Scope 2:39).

Greg: your project is OK with MXF OP1A DNxHD 1080i 220/185/175 10 bits but you have to check "Enable Video Fiels Processing" since you had asked for "Fiels Rendering" in the delivery page. => DNxHD = HD.

For 2K you need another CODEC.
Can someone confirm?

Hello Jean-Claude,
Thanks for your input. You are right this codec is HD only but I've set my render job to HD. And this has no effect to the issue actually.
Concerning the "Enable Video Fields Processing" option I have to disagree with you.
All my tests have come to the conclusion that this option is only valid if all your footage is interlaced. If your footage is progressive, you must untick the option otherwise the fields are corrupted. Try to render some text with "Enable Video Fields Processing" enabled and you get some kind of double interlacing that bring ultra aliased edges.
Regards.

EDIT: I've just double-checked. Set the project to HD. Enabled "Enable Video Fields Processing". It brings even more artefacts...

Hi Jean-Claude,

This issue is specifically related to the XDCAM MPEG 2 codec in an MXF OP1a container, not other codecs. I've also tested with DNxHD and not had a problem, but broadcasters require XDCAM MPEG 2, not DNxHD. Also, it's usually interlaced that they need too.

Hey there,

Just poppin' in from another thread which had a link to this topic.

Unfortunately, I'm on mac and don't see this issue (and anyway still on 15.3) but yes, MXF OP1A XDCAM MPEG 2 is what's needed by broadcasters, Sony is even selling an online upgrade for a range of cameras that didn't feature it by default.
By the way, let's quickly write among french users hahaha :D : JC, Greg is right, Resolve cannot [i]create interlacing if native footage was not interlaced; it can only carry on interlacing during the whole WF (still if it really was the original format). Fortunately a lot of tools exist for those who... forget to shoot this way...[/i]

Now, I'm interested in how BMD will fix that and/or by what caused it (i.e. the way the win encoder is implemented)

Clip attribute is well interlaced 'Auto'
If in the delivery page Greg want to get interlace (comme il l'a fait) , it is better to check "Enable Video Fiels Processing" in the project. No ? :)

Yes, correct.
It appears we chatted about 2 different topics, and his message led me to think he had no interlaced footage, but actually yes, it is 50i.Therefore the option is indeed to be ticked to keep interlaced clips until render.
Anyway his issue is connected to Resolve16 and up + Windows : if one of these 2 conditions is missing, he will have the issue so far...

Re: MXF OP1A XDCAM MPEG 2 Export Issues on Windows

Coming over from another thread where this was mentioned.

I cannot reproduce this issue. Tried animated large white title over UHD mp4 footage. No issues exporting xdcam 422 .

I suggested that perhaps turning off GPU hardware DECODE in preferences may help. Some one give it a try and RSVP.

Look back in this thread and download Greg Ausina's test project and try it. I just tried it again with the GPU decoding of h264/265 switched off and I still have it. Greg's footage is Apple ProRes so the GPU decoder wouldn't be working anyway.

@kinvermark
Did you manage to export the files without the bug?
Are running it on windows?

I've tried Greg's project and definitely have the problem (this is on the final release of 16.1).

Maybe we should help the devs out a bit more by providing the following information. It should be both those who have the problem and those who don't, so we can try to identify a pattern in the configurations between both cases.

Do you have the problem?
Windows version & build:
CPU make and model:
GPU make and model:
GPU memory:
GPU driver version:
RAM amount and speed:
Any additional codec packs installed:

Here's my info:
Do you have the problem? Yes
Windows version & build: Windows 10 1903 build 18362.418
CPU make and model: AMD Ryzen 7 3700X 8-core 3.6GHz
GPU make and model: NVidia GeForce RTX 2070
GPU memory: 8 GB
GPU driver version: 419.67
RAM amount and speed: 32GB @ 3200MHz
Any additional codec packs installed: K-lite Codec Pack 15.0.4 Basic, QuickTime 7, NewTek Video Codecs - SpeedHQ (problem existed before this one was installed)

@iddos

Sorry, bad news. Didn't export properly here either. I am trying a few things.

On the good side, it should be easy for BMD staff to reproduce the issue.

Mark, you say you attempted to recreate the bug with another file and that was OK. Maybe provide that file so we can see what the differences are and what might be a factor.

Now I can see the signatures on posts (using my computer now instead of Tapatalk), I see we have a range of different graphics cards, drivers, CPUs, etc that are affected. So it's a Windows version issue. Has anyone tried the Linux version to see if that's affected too?

@Michael

I can upload... but first let me do some more testing. Footage was simply GH5 UHD 23.976 Mp4. I used title generator and dynamic zoom to create a moving title. Exported fine. Took exported MXF and reimported ad re-rendered. Still worked. Checked again just now. OK.

However, I just tried BM's R15 Training project and it didn't work. Prores again. Hmmmm? I wonder...

Mark, I've had trouble with H.264 as well. For me, it doesn't matter what codec the source footage is. Initially it was ProRes, then I tried H.264 with no change in the result. I also tried an MXF exported from Premiere Pro as well as from DaVinci Resolve 16 for Mac, and still no change in the result.

If it were a problem with the source file codec, wouldn't we see this problem in the edit viewer?

Yes and no, depending on how the rendering process actually works compared to the edit viewer.

I thought that all source files were converted to RGB linear light 32-bit float, then effects were applied and then the rendering to the output codec would derive from the RGB linear light 32-bit float. If it's different from that, how so?
