detinterlace node gives sync audio issues

Hi

I don't know if it is really a bug but when I put a deinterlace node in my workflow, the sound become out of sync progressively (1 stereo track or 2 mono tracks file)
I have tested with IMX d-10 and AVID DNxHD processor and it gives the same results, the sound is out of sync. If a delete the de interlace node the sound is fine.

My workflow is : Watch folder - A/V MEDIA - Deinterlace - IMX D10 - Folder
Very simple :)

I'am on windows 7 pro and I run 0.9.4.0 FFAStrans version.

If someone have an idea, it could help.

thx

Hi,

How is the "A/V Media"-decoder configured? Is it "Intelligent" or "Full decode"? Also, if you use some other encoder, do you still see the same behaviour?

Hi steinar

It was set to "intelligent".
But before answer here I have done some other tests and it seems to be a little more complex.
In fact My workflow has two deinterlcae node.

In this configuration I'am out of sync whatever I set on the AC media node.
Now if i keep only one deinterlace node on one branch, and I change the setting on it : it works fine ! (the branch that has the deinterlace node of course)

I attach the workflow to see if you can reproduce the bug.
It completely drives me crazy :)

Thank

Hey Ghatis,

i imported and tested both branches of your workflow but i cannot reproduce any audio async issue using your workflow.
My input sequence is a audio sync test about 3,5 minutes.
Any further hints how to reproduce?

Hi Emcodem

thank you for your help.
I don't know what happen with this workflow. I will investigate more than I did at the end of my holiday.
I will try it on an other computer to see if i can reproduce this bug.

bye
