[BUG] audio not synchronized after cutting videos

[weyb06]

hi,

so i tried with the 2018.10.05.1 version
you have here the capture of the deployed job queue (i don't see any qp reference, so I didn't started the job), and here the level 9 log

1st Delete old HybridDebugOutput.txt before you create one you want to share with me, since it saves me a lot of nerves reading through old log content.
2nd read the sticky again and note when the DebugOutput is turned on. (Not interested in all the startup data unless there is a problem with Hybrid starting,..)
so 21981 lines later,....

I see that the Chapter file is created by not the .qp file.
There still seems to be some bug,.. works here, but something in your settings seems to cause Hybrid to not properly parse the encoding call.
-> looking into it

[Selur]

Did you disable 'NVEnc->Misc->Key frames for chapter' ? (option is on by default and if you disable it you won't get the key frames where you want,..)
When enabled the NVEncC-call should contain '--keyfile GENERATED_KEY_FILE', it doesn't in your call.

LOL, just checked the 'Key frames for chapter' option wasn't default in the last dev since I did some testing and disabled it.
-> you need to enable that option for things to work as they should.

Hi,

i still have the same problem 

My method :

I. Create a new proper file in the target format I want :

1. set a default output folder
   
2. load source
   
3. adjust Input PAR 1x1
   
4. do cropping and filter
   
5. add chapter points and name them according to the episode
   
6. configure audio to passthrough all &video to NVEnc
   
7. NVEnc->Misc->key frames for chapters enabled --> i saw the qp file information in the Jobs tab
   
8. encode the file
   
9. i check the encoded & chapterized result before going on : the audio is synchronized
   
   

II. Split the file and name the output files after the chapters :

1. load output of previous file as source
   
2. set audio&video processing to passthrough
   
3. enable Config->Output->Filename Generation->Output Filename Generation->Use chapter names
   
4. enable Base->Generate
   
5. hit 'Queue Chapters' to let Hybrid create the jobs to split the source into the chapters and name the output files according to the chapter names
   

but after this, only the 1st "chapter" has the audio synchronized, the others have not 

hybrid version : 2018.10.05.1
base->processing->video = NVEnc
NVEnc->base->codec : h265 ; encoding mode : constant quantizer ; quantizer : 28
NVEnc->Misc->key frames for chapters enabled --> i saw the qp file information in the Jobs tab


the log is here

I have an other curious problem, and I'll create a new post.

regards

EDIT :
I see at the bottom of NVEnc->Base, the command line, which contains --fps 25.000, so I understand that the video track is encoded with this framerate
-> could it come from that, as i chose "passthrough" for the audio track ?
Is there a way to choose "same framerate as source" ?

[Selur]

Hybrid by default should use the frame rate of that the source was detected at. (assuming the source if cfr and not vfr)

I see at the bottom of NVEnc->Base, the command line, which contains --fps 25.000, so I understand that the video track is encoded with this framerate

Can't see that anywhere in the debug output.
Encoding call in the debug output states:

-> no clue where you saw the 25fps, but it doesn't look like it was used anywhere.

If Hybrid would have been 'oiff' with the frame rate, the reencoded output would already be asynchronous.

-> no clue why it isn't working for you

hi,

here is a screenshot of where i saw --fps 25.000 (at the bottom of the picture here you'll see --fps 29.970)
but i didn't see it right now & can't remember how i got it this morning.
have to make other tests...

regards

[Selur]

25fps will probably be shown if no source was loaded since 25fps is the default,..

[weyb06]

hi,

here is a little video (13sec - 2MB) with 4 chapters
the audio is sync.

when i split it according the chapters with the queue chapters, the audio tracks aren't sync anymore (except the 1st)

could you make a try with it please to see if it works for you ?

regards

[Selur]

Doesn't work for me either.
