Encode to XDCAMHD 422 Freeze Frame

[Jakida]

Hi,

First of all i want to thank you for this great tool. It saves me a lot of time. I've updated to 0.8.1

I have a *.mp4 video that i should encode to XDCAM422. My workflow is attached. My workflow is working for most of *.mp4's, *.mov's *.mpg's but sometimes it encodes freeze frame before last frame. this link contains my source video: https://we.tl/58Wj6IuRlu
If you try my workflow, 3181th frame is the freeze one. Source video have 3182 or 3183 frame. I've tried differents computers too.
The thing is it is working on 0.7.7. 0.8.1 encodes twice as fast for me and i want to use new one.
-Sorry for my english-

What am i doing wrong ?

Regards

Hi Jakida, thank you for using FFAStrans and welcome to the forums!

And thank you for the bug report and the test file. That is really helpful! I will investigate.

This looks like an issue with the never versions of the h264 reader in the ffmpeg library. You will also get weird behaviour on your file (in 0.7.7) if you encode without using the "A/V Media"-decoder. So, I'm not sure how to deal with this: The AviSynth media reader (ffms2) in FFAStrans 0.7.7 is old and have limited support for new features in AviSynth+ branch shipped with FFAStrans 0.8.x. I hesitate to go back to older versions of ffms2 because of this but you can try an work around this on your own:

If you copy the files in the following path from your old FFAStrans installation:

...FFAStrans0.7.0\Processors\AVS_plugins\ffms2

to

...FFAStrans0.8.0\Processors\AVS_plugins\ffms2\x86

then your workflows should behave as "normal". Please try this and report back.

Hello,

I can confirm that it is working again when i changed these files. Thanks a lot

Should i keep watching new versions for ffms2 and give a try if new version released ?

[admin]

Great!

You can do that if you want, no problem. But be aware that new versions may have other issues. Some builds simply does not work with FFAStrans.

Hello, My issue appeared again from v 0.9.x.
This time i guess it is not related with A/V server i guess. Because If i use custom FFMPEG encoder, it encodes .But with XDCAM encoder, there is empty frame.

I've uploaded 2 files: https://drive.google.com/open?id=1Pnwsv ... SFkTK-2dD9

one is my workflow, other one is the video (.mp4) that i want to transcode to XDCAM .mxf
Video has 169 frame and after transcode, 167th frame is the empty one.
Any help would be appreciated

Hi Jakida,

I'm not able to reproduce. Using your workflow and mp4-file, the output mxf file is pretty much identical to the original, apart from the properties. No missing frames as far as I can tell. I loaded both files into Premiere and both look nice and dandy. Where and/or how do you see the missing frame? Maybe you also can share your output mxf file with the missing frame?

Hello,
I've prepared a video about my operation. To explain more, our systems accepts mxf files. We are transcoding mp4 or mov files to mxf via FFAStrans.
If you watch the video there is a scene showing an error "read video failed frame 167". That is like a quality check server. After that i've used Sony Xpri editor and as you can see there is empty frame.
My video and output mxf files links are below

Thank you for your interest.

Well, I don't have access to the NLE and QC you're using so it's a bit difficult to recreate and investigate. Does the issue occur if you submit a file directly to the "XDCAM-HD" encoder?

[Jakida]

Yes, unfortunately it does.
But if i use Custom ffmpeg (you can see it as a encoder on my workflow) it transcodes without any frame issue.
I am not using custom ffmpeg because i couldnt configured audio. You know, XDCAM should have 8 mono audio and sometimes our inut video has stereo sound, sometimes input video has 4 mono audio...
