Comclean cuts cause video to freeze

[funkybro_uk]

Some mpeg players can handle these not continous timelines.
YOu will find out if your is robust.
If not, run retime after comclean or use comclean2.

Hi Erik

Just discovered your retime app. This sounds just the ticket for me, as my DVB-T reception is not perfect, and transmission errors confuse the skipping functionality in GB-PVR and also cause lipsync errors.

How long does it take to retime, say 30 mins of video? Is this something to run overnight, or can it be done in the background without disrupting GB-PVR usage (with MVP).

Also, how difficult/trivial was it to implement this? I record lots of DVB radio using GB-PVR, and would like to implement an app which checks to see if the video component of an mpeg2 is present, and if not, to demux the audio out, and transcode to mp3 using lame. This will save me the hassle of doing it all manually (using TMPGEnc currently). Does this require special MPEG knowledge, or can it be done using DirectShow for instance?

Cheers

Erik:
Oh, no! I've just got comclean running well. I do watch videos from within GBpvr, on the MVP, so far all has been well. If i read this correctly i'm about to have problems with it? The reason i moved to comclean was GBpvr was not skipping consistantly, if at all.

To be honest, I wouldnt recommend anyone uses comclean. It does truely evil things to the file. It will definitely cause more problems with GB-PVR when trying to skip.

If you're using comclean to skip the commercials you could always check the box in the config app to automatically skip them for you. If you're using comclean to make the file smaller, you could transcode it as well.

DOn't expect miracles from retime.
The only thing it does is split the mpeg PS into separate mpeg video and audio files (now you can check if there is no video and then convert the audio to mp3) and then muxes both files again together into a PS.

I agree with sub, if you use GBPVR (or zoomplayer) to watch then better not use comclean.

But for those that can not do playback on a computer but use networked mpeg playback devices its is a quick and very dirty solution. My family realy likes it.

If all I'm trying to do with the comclean processed mpg file is burn it to a dvd, does it matter that the timeline is messed up and causes some decoders to crash? I mean, will the mpg be able to be burned to a dvd and play without problem, even though it would crash when played in a decoder on the computer?
Also, I know that I need to demux my mpg files before they can be burned to dvd with the myvideos plugin. Is the demuxing/remuxing that is done in either comclean2 or retime the same thing, and I wouldn't have to demux/remux again before burning to dvd?

Sub - Does your warning about the use of comclean (with which I agree) apply to comclean2 also?

[sub]

I dont know anything about comclean2. If it does the same thing as comclean, then yes.

When burning to a dvd involves demuxing then the timeline will be automatically repaired. This implies there will be normally no more problems (I never heard about any)

Comclean2 does the same, it demuxes and then is muxes the video and audio again into one file. That is why I assembled comclean2. Some guy (forgot his name, sorry) tried to use the DLink network media player and it could not handle the files from comclean. Now with comclean2 his problems where solved.

May I suggest you test both comclean2 and retime? If retime works OK its simpler because you do not need to install cuttermaran separately

Yeah, from what I understand by reading the myvideos wiki, and the dvd burning for dummies guide, the mpg is demuxed and remuxed into a dvd compatible format before it is able to be burned. I just wasnt sure if the muxing done by myvideos is the same thing that is done by retime/comclean2, or if all muxing is the same as another (i have no idea what muxing is lol). Myvideos has me run convert.bat which is:

Code:

"C:\utils\cmdshell\cPVAS.exe" "t:\demux.ajb"
rename "t:\temp - DELAY*" "temp.mpa"
"C:\utils\dvdauthor\mplex.exe" -f 8 -o %1 %2 %3
del "t:\demux.ajb"
del %2
del %3
del "t:\temp.mpa"

After this, the resulting file is another mpg that seems to me, identical to the original. I'll have to check if this muxing process fixes the comclean freezes due to the timeline being messed up.

Apart from comclean2 and retime using mplex1.exe i.s.o.mplex.exe its the same.
