Missing Video

[pschweig]

I captured a film from NTL cable using my Hauppauage PVR-250. The resultant mpeg2 file was 9.58GB.

I then used Videoredo to clip unwanted bits from the beginning and the end leaving me a file 7.62GB in size.

I authored DVD files using DVD-Lab. No menu, just the video. DVD rebuilder reports one Video Title Set (7,833MB 4:3) and one audio stream (2Ch MPEG-1 English).

I have purchased CCE Basic to perform the encoding.

My problem is that the dvd produced by rebuilder has no video just audio. I have an .m2v file in my working directory which I can play in media player and contains the video. I have successfully used rebuilder for other mpeg2 files captured from my pvr-250.

Anybody know why this is happening. I still have the authored VOB files and all the files rebuilder created if that helps.

thanks

Hi

I'm still having trouble with this one.

Rebuilder is giving me audio but no video. There is no orange/red line at the bottom and I have ticked add to avs file next to the mpeg2dec3g path in setup.

The avs files in the d2vavs folder play the video through virtual dub. Does this mean there is somthing going wrong in the rebuild phase?

The files in the video ts folder are clearly not big enough to contain the video. There several vobs in the authored dvd - but only one in final video ts folder. ie VTS_01_1 - VTS_1_07 but in final video ts only small VTS_1_01

For a dvd that is small enough to fit on a dvd-r already, the dvd created by rebuilder plays correctly. I managed to successfully rebuild a rented dvd which was dumped onto my hard drive using dvd decrypter.

Am using rebuilder 0.54 and powerdvd to play

Any ideas as to what could cause this??

If your seeing the orange/red line it is definitely an AVS/CCE encoding problem and not a rebuild problem.


Try this, the only problem is I don't know if Basic can do this.:

Open CCE directly. Drag and drop one of the AVS files into the window.

That should add an encoding job to the window. (the duration should be 10 seconds, which means the file isn't rendering properly). Right-click on the job and select 'edit'. Near the top of the new window there should be a 'settings' button, click it. You should see the file listed there, double-click on it to open the video and see how CCE decodes it. You should see an error message in the video which tells you what the problem is.

If you don't see the error there, it is possible an access violation (a AviSynth or plugin program error) will pop up after the video plays for a little bit. I haven't seen this unless I encounter a funky combination of plugins, so unless you are using custom scripts this is unlikely. In any case, try searching around in the video and see if an error is generated.

I'm not seeing the orange/red line. The avs files created in the working folder play fine in virtual dub and I can see the video. Does that rule out encoding problems?

I am currently trying to rebuild the same mpeg2 file but authored with ulead moviefactory instead of dvd lab.

Does anyone else use dvd lab and dvd rebuilder?

I may be completely back asswards in my thinking here but why wouldnt you encode the m2v file first with CCE (Not using rebuilder) and then run it though dvd lab and burn? Not to disparage rebuilder or anything I love it and use it myself, but its not really NEEDED in this case.

[wmansir]

Sorry, I misread your post and thought you were getting the orange line, but the .avs files looked fine in Vdub. If the .m2v files created by DVD-RB look fine it isn't an encoding problem. It appears to be a rebuild problem, but I don't know enough about that phase to help.

Check and see if the output M2V is greater than 2GB. TheSeeker asked the best question. Why not just use AVISYNTH against your MPEG source, reencode, and then reauthor. I'm very proud of DVD-RB... but if you are going to take the time to author it anyway, why do it twice?

[pschweig]

thanks for the help everyone.

JDobbs - The m2v file is 3.9GB in size.

I will try what you suggest with avisynth. As you can probably tell from this thread I am a beginner, could you suggest somewhere where I can find guides on avisynth?

[jdobbs]

Try setting chapters throughout the video when you author. Your individual cell(s) are too large (there's probably only one). There are a lot of good reasons to do that... like, for instance, not having to fast forward through 50 minutes of video to get to some point at minute 51.

You will also need to use mpeg2dec3dg.dll for feeding the source to CCE (just like with DVD-RB), in fact you may just want to look at some of the AVS sources that DVD-RB created for you as an example.
