Oh its probably been covered...

But I'm forced to ask anyways. I'm using the Divx 5.02 Gnot guides, and its not working out.

I tried Rush Hour 2, and Mothman Prophecies. The first hurdle is file size. I understand that movies compress better in 5.02, and some movies compress more than others, but I'm using the full DD 5.1 soundtrack ( or I want to anyways ) and its around 228MB for Rush Hour 2. That leaves me only 570MB for the movie on 1 CD, so I doubt the quality will be what I want. I wan to spread it over 2 so I manually enter 1180MB, plus 228 should fit fine on 2 CD's.

The slider however won't let me select a value of 0.25, its off the chart, so I just select a value that gives a good error ratio and higher bit/pixel value. I follow the instructions and run the 5% check, it runs, says "finished" but doesn't load into the GNot window for a quality value, and displays a Compressibilty Check error Divx 4.11 in the encoder window. I'm running the 0.26 Gnot ( with Divx 5 selected ), and Divx 5.02 Pro, so why is it checking using the Divx 4.11 codec?

So I just ignored and encode without the check. It runs all night, displays and encode time of 8 something hours in the morning, and I end up with 2 299MB files, both the entire movie, both crappy quality. I selected both passes in the options field, and all the other values from the guide are identical, save for I encode without audio and was planning on taking the AC3 file DVD2AVI creates and adding it after.

I'm not sure what I'm doing wrong here, and I've also tried MPEG2AVI, but it wants to encode using only 4.11 not 5.02, so I don't want to waste time creating a bunch of older codec videos.

Help!!

PS: Feel free to get technical, I'm a Electrical Engineer and my roomate is a Computer Engineer, so between us we can handle code changes and pretty major tweaks etc. Until now we've used MPEG2AVI, but I want to try GNOT and Divx 5.02.

Thanks.

Sounds to me like your divx 5 codec is not installed.

Its not part of the gknot pack I think. Are you sure you installed divx 5.02 properly? Perhaps try re-installing the codec?

[ryankenn]

OK. I checked my video codecs and what do you know, the only ones shown installed were "low motion codec" and "high motion codecs" that came with the Mpeg2AVI I installed.

I uninstalled everything, and reinstalled only 5.02 and the Gnot finallly worked!! The video is great quality and it only took about 6 hours on my PIII 550.

Now I have a specific problem with Mothman Prophecies. Using Rush Hour 2 as a test, a created a DVD2AVI project and ended up with the AC3 audio track for it. I could play it in Media player, and it was able to be decoded by my SS amp into true 5.1. Good stuff. With Mothman, the 1st track is still the English 5.1 track, so I select and and create the project. The only problem is I end up with 2 seperate 380 MB AC3 tracks, both 448 Kb, and neither will play in Media Player until interlaced with the actual movie video. Neither however will actually decode into DD5.1 through my receiver.

So:

1) Why is DVD2AVI making two audio tracks? I only selected track 1.

2) Why won't this AC3 file play in Media Player like the ac3 file for Rush Hour 2 did?

3) Now that I've joined the audio to the video, and I stupidly deleted the video only avi, is there a way to strip the audio back off the video so I can perhaps fix the sound and reattach true 5.1 audio?

Thanks

1) Make sure DVD2AVI is set to "Demux" and not "Demux All". That way, it will only extract your selected track.

2) No idea. But if it works in the final AVI...

3) To strip the audio, you can just open AVI in VirtualDub and choose the "Save Audio as WAV" function. Which will give you an AC3-WAV.

But...you said you stupidly deleted the video-only AVI. If all you want to do is add a newly ripped audio track, just delete the AC3 files, open up the VOBs in DVD2AVI, and create another project. Then load nandub, and open your final AVI, and then just choose to replace the Audio stream with another AC3. Set the interleaving options, video on direct stream copy, and save to a new file.

....load your interleaved AVI into VDub(or NANDub, whatever...), select 'video, direct steam copy', then 'audio, no audio', then 'save as'.
