Which MPEG editor uses the correct frame numbers?

[erik1958]

Lately I have been trying to generate frame accurate cutlists by Comskip for automatic editing.
So I compared MPEG2CUT2, Videoredo, MPEG2VCR and VirtualdupMOD on their frame numbering and found they all act different.
When looking to the first frames of a recording, they do not even start with the same frame.
How is that possible?
How to generate automatic editing frame numbers when all the editors act differently?

I don't have a direct answer, but try Cuttermaran as well. Set Comskip to also demux automatically, then run -

Comskip capture.mpg
Cuttermaran.exe "E:\path to created by comskip\capture.cpf"

Comskip.ini

output_demux=1
output_cuttermaran=1

Will try but I want to be able to support videoredo because many people seem to use it.

How fast is cuttermaran in cutting and muxing? I have a slow PC.

Most cutters will cut on the I-frame interval only.

Some will do frame-accurate cutting and re-encode the interval. Don't think any freeware does this.

Cutting captured files often results in audio synch issues. Results may vary depending on capture equipment.

Cuttermaran has worked well for me, also MPG2Cut.

Worst case scenario, the TRIM function in the Sonic MyDVD authoring package is able to correctly trim files that no other program will handle. I-frame only.

Cuttermaran coupled with QuEnc allows frame accurate cutting with minimal re-encode for free.

This works really well. Turn off automatic demux, as the Xport.exe utility does more accurate demuxing.

comskip capture.tp
xport.exe capture.tp 1 1 1
ren bits0001.mpv capture.m2v
ac3fix bits0001.mpa capture.mp2
Cuttermaran.exe "E:\path\to\capture.cpf"
mplex -f 3 -b 1850 -r 25000 -o Capture_Clean.mpg capture_clean.m2v capture_clean.ac3
