The most likely reason for the master/slave export issues is that the CLI template is using %(outputname) instead of %(outputfile). The former is just the filename while the latter includes the full path; in the actual command line you want the full path. |
So when we create our encoder sets, should we use %(outputfile) instead of %(outputname)? Not for master/slave but in general.
I'm having an issue with some encoders that I'm testing where Virtualdub refuses to create the file because it either can't find the file path or the filename already exists. I've never been able to mux anything besides mpeg2 with ffmpeg.exe and some encoders I've been experimenting with lately give the same type of error when trying to encode the video.
I don't have any problems using ffmpeg to encode or mux on it's own but when I use the same argument with ffmpeg in Virtualdub external encoder, it always fails. I had heard that a lot of things broke with newer versions of ffmpeg so I downloaded the oldest version that I could find (5-2011) to use just for muxing but it still doesn't work.
One thing that I've noticed is that ffmpeg will give the video the container name webm instead of the fourcc name vp8 or FLV instead h263 and this breaks the external encoder since Virtualdub already has the filename.container listed in save as. If I try and change the extension, it overrides it with xxx.vp8.webm (or whatever file type I'm trying to create) and still fails. If the external encoder gave you an option to overwrite the file that it thinks it sees with the files that it just created instead of just failing and deleting the files it just created and leaving an empty container, that would be nice. When using the command prompt, you usually get that option. |

Aaah... it works! Im sorry I thought it was a bug, but I've tried so much..
Thanks for your support! |

Always use the *file variants unless you specifically need to do name hacking, i.e. creating another similarly named filename. In the latter case, use %(outputdir) and %(outputname). For instance, you could pass %(outputname) and %(outputdir)\%(outputname).stats.
Also, remember to quote filenames appropriately so things don't blow up when there is a space in a directory name.
Regarding tools picking their own extensions -- this is not ideal, as then VirtualDub doesn't know what file is actually getting produced. However, I've added a %(outputbasename) tag so that you can get the base filename without the extension.

I was able to fix the problem with ffmpeg by adding -f webm -y "%(outputname)" as recommended by another user.
Using -y overwrites the existing file. I'm not sure I even need to use the -f command but it works so I don't want to change it. |

IVTC filter
Reducing frame rate can produce denominators too large for some codecs (tested with x264vfw)
After calculating the 4/5 reduction, the denom/numerator can be above 0x80000000 which causes a codec error (value too high)
Also, the IVTC only does 5/4 reduction, but 6/5 is also common in 25->30fps clips

This is a bug in x264vfw. Stream sample rate fractions are unsigned integers and values above 0x80000000 are valid.

If you mean this error:
| CODE | x264vfw [error]: Effective timebase denominator 2147483650 exceeds H.264 maximum
x264vfw [error]: x264_encoder_open failed |
Than that is not x264vfw's bug but exactly what is written: limitation of the specs. x264vfw correctly process fps information as uint32_t/uint32_t up to this check. |

@Altaf
You'd have to give a better description - final stage of processing probably means something to you, but could be anything
Are you cutting compressed audio?
If so, then you will get differences in length
That's due to compressed audio being stored in frames of a certain time length
You can only cut that audio on the frame, not in between
These frames hardly ever line up with the video frames, so there will be a difference between the two values
To cut the audio exactly on video frames you have to work with uncompressed audio

@Altaf.. Drag and drop videos to the Batch Wizard it is a known problem as there is no filter select to load the videos with. which I have reported previously on a Virtualdub beta thread. We still wait for Phaeron to add code for it to work correctly |

Test-12 is up with expanded format support in the resize filter and a token-dropdown in the external encoder setup UI.
Anyone know what the fraction denominator limit for H.264 is?

All I can usefully find is this in x264's source code
| CODE | if( (uint64_t)h->param.i_timebase_den * 2 > UINT32_MAX )
{
x264_log( h, X264_LOG_ERROR, "Effective timebase denominator %u exceeds H.264 maximum\n", h->param.i_timebase_den );
goto fail;
} |
