CCE and cyclic redundance issue

[Mirdur]

Hi Guys, hope some of you can help me solving this problem,

The problem is happening when I am trying to encode an .avi file using the CCE . I encoded tons of .avi files before using one of the guides in this forums and never had any problems untill now.

When the CCE ends encoding the .avs file of the .avi movie that i want to convert, the resulting .mpv has the cyclic redundance issue, so i cannot write it in DVD. I discovered taht the problem is of the CCE and not of my authoring and burning programs when i tryed to open the .mpv file in virtualdub, and it also said that the file had a cyclic redundance issue. I thought also that the .avs file that i made of the .avi file would be the problem, but it didnt show any problems when i opened it in virtualdub. Also the .avi file shows no problem when I play it.

It seems to me that the CCE is the reason of the problem, I use all the specifications presented in the guide in this forum and I have done the same before and never had any problems. Here are the configurations i used.

First thing I would so is untick the For DVD box. I would also push up the bitrate is this is the only thing on the disc, as you have plenty of space to spare. Other than that, your CCE settings look OK.

Cyclic Redundancy issues are usually related to drive problems, not encoding.

You have MULTIPASS VBR selected but then for PASS (meaning number of passes) you have "1" selected ... this of course makes no sense. If doing a MULTIPASS VBR encode you must set PASS to at least "2" ... unless you change to a "1-pass CBR" encode etc.

Also I don't use MP2 audio but I think STEREO is a better setting than JOIN-STEREO but I don't know other than to ask why aren't you using AC-3 audio?

Missed the number of passes - good pick-up

Fulci:

Actually the 1-pass shouldn't make a difference as CCE will just do 2 passes anyway if the .vaf file hasn't been done yet. If you let CCE do its thing for a new encode it always does "1 more" pass than what you indicate under multipass VBR as it always writes a .vaf file first. If your .vaf file is written already, and if you were to encode at a later time, then doing the setting as "1" for multipass VBR it will only do 1 pass for the final encode.



Mirdur:

Maybe you're writing to a specific part of the drive that has errors. Try encoding with a different encoder and see if you have the same issues.

Nah, choosing 1 pass means he's doing 2 passes, the VAF creation pass, followed by the 2nd pass where the video is written. When the actual encoding starts it'll show as 2 passes. CCE has a screwy way of numbering the passes, as it doesn't count the VAF creation as a real pass.

In section 2.14.1 of my manual, it says:

When you carry out encoding without existing video information file, a single pass for creating the file will be added first automatically. So the number of passes actually done will be one more than specified

I'm not positive why he's getting the CRC error. One possible reason might be that he's having CCE do the audio. I'd disable the audio in the .avs if I were Mirdur. And I don't know if checking that CRC box has anything to do with it. My second (and much better) possibility is that he needs the CCE Checksum Patch, sometimes called the CCE CRC Patch. I'm having trouble finding it. I think a search followed by registering at CD Freaks will find it at their forums. I know he can get it at the DVD2SVCD forum at Doom9, but their forums are down at the moment.

Edit: Pinstripes23 beat me to it while I was unsuccessfully looking for the patch.

Well I know about that first pass being the VAF creation pass but I thought that didn't really count, i.e., I thought you still had to do 2 or more passes after that for a "true" multipass VBR encode.

Thanks guys for the help. The problem was that i didn't defragment my disk drive in a long time, after i defragmented it, all was well.
