Selur's Little Message Board

i want to encode a file, it displays added when run encode button, but the state displays finished. can't encode

Seems like you accidentally misconfigured your settings and used 'specific filesize/bitrage (2pass - 2nd pass)' when you should have used 'specific filesize/bitrage (2pass)' as encoding mode.
According to the debug output you created a job where only the 2nd pass of a 2pass encoding is included.
Hybrid allows this, but it can't start the encoding since the stats file that was specified doesn't exist.
-> doesn't look like a problem of Hybrid, but a mistake on your end.

you mean i should not use 'specific filesize/bitrage (2pass - 2nd pass)' , i should have use 'specific filesize/bitrage (2pass)' instead?

but i using 'specific filesize/bitrage (2pass)' get the same result, can't encode.



i close hybrid, then restart, and clear all jobs before, then encode, this time can works.

Unless you know what you are doing (which does not seem to be the case): Yes

Quote:but i using 'specific filesize/bitrage (2pass)' get the same result, can't encode.

Can't reproduce that here.
So:

• clear your job queue
  
• delete any old debug output file
  
• use 'specific filesize/bitrage (2pass)'
  
• enable the debug output
  
• create the job
  
• rename, zip and attach the debug output
  
• start the job processing
  
• in case it gets stuck zip and attach the 2nd debug output too

thank you, and i also want to know, this clip is 29.97fps, if i want to encode it to a 25fps, how to?

try to tweak frames then encode get crashed, new

According to the debug output there is a problem with decoding the Vapoursynth script.

The script itself:
and the encoding call used:
both look fine on first glance, but the first part of the encoding call has problems decoding the script.

This is usually happens when:

• The source filter has a problem with the source, then switching the source filter might help.
  
• The source is buggy, in some way. Then you are out of luck.
  
• The script requires more ram than your system has.
  
• Something filter that is used in the script doesn't properly work on you system.
  
• Some problem with the setup, in example a messed up Vapoursynth folder. -> deinstall Hybrid and install it a new.
  
• Some other tool is interfering with the encoding.
  
• System is instable.
  

-> Check the Vapoursynth Preview to see whether it works.
If it does not it should show an error.
In case it does not show an error also call the encoding call inside a Windows Command Prompt to see whether there is another error shown that Hybrid doesn't log.

-> LWLibavSource can't handle your source clip.
Since it works fine here, it highly likely there is something wrong with the clip.

Also try:
a. (if you have an NVIDIA graphic card) enabling "Filtering->Vapoursynth->Source->Use DGDecNV when available" and see whether the preview works
b. disabling "Filtering->Vapoursynth->Source->PRefer LWLibAVSource over FFMpegSource2
If both do not work then the cause probably is your source video.

yes, tried, a and b both works, can see preview now, and can encode.

but i using mvtoolfps  filter set fps to 25, the encoded clip is still 29.97fps
