Retime/mencoder

[the_e]

Hi,

I'm trying to clean up some recordings (cut out commercials/padding) to put them on dvd. Some of my recordings with my Nova-t (9002) seem to have the wrong timestamps so that I have to fix the timestamp before I can run comskip -- otherwise comskip recognises the commercials, but they are in the wrong place when playing the file in GBPVR.

I downloaded "retime" from the wiki and set up a batch file to manually start it:

move "%~dpn1.mpg" "%~dpn1_faulty.mpg"
cd "path\to\retime" (yes, I have the correct path here :-))
call retime "%~dpn1_faulty.mpg" "%~dpn1.mpg"
del "%~dpn1_faulty.mpg"

For whatever reason, the audio is slightly out of synch when I play the retimed file.

I then tried mencoder -- also starting from a batch file:

move "%~dpn1.mpg" "%~dpn1_faulty.mpg"
"C:\Programme\devnz\Tools\mplayer\mencoder.exe" -idx -of mpeg -ovc copy -oac copy "%~dpn1_faulty.mpg" -o "%~dpn1.mpg"

When I play the file in GBPVR, I can't skip and the timeline shows "0:00:00" at both ends.

I have no idea which tool is better (retime or mencoder) so any suggestions would be appreciated as to which to use and how to use it (please keep it simple)

I've found the same problem you have with mencoder. If I use the -ovc copy option, it's fast but the duration of the video shows up as 0:00:00 in anything other than Nero Showtime. What Nero does different than other players I don't know.

The only solution I've found with mencoder is to use other -ovc options. I currently use the statttik_transcode.bat batch file you'll find in one of this board's other threads. It makes mencoder re-encode the mpg so it looses it's blazing speed, but the timeline is correct at least.

might try:

Code:

ffmpeg.exe -i "%1" -y -target dvd -g 15 -bf 2 -cgop -me x1 -vcodec copy -acodec copy  -f dvd "output.mpg"

or i have a directshow muxer that is as fast as it will ever get...[does a true demux with directx speed] i have a graphedit graph that i use for that..
[basically just use file reader->demux->muxer->file writer in graphedit]
