Couple odd CCE results... anyone else?

[Pisces225]

I don't have a question about what I'm doing, I've done tons of perfect encodes, but I've gotten a few odd results out of CCE lately.

I did a series of encodes recently where it only encoded the first few minutes of the .avi and then encoded the rest of the frames with video showing an error message regarding illegal memory access at certain locations. Anyone else ever seen this?

I also did an encode recently where CCE reported the encode as completed, but when I looked there was actually no files from the encode. No VAF, no MPV, nothin'. So I redid it. This time it encoded the first 20 min. or so perfectly and then just stopped. By stopped I mean the encode seemed to complete properly but it only resulted in a 350 meg mpv (when it should have been over a gig). It's an episode of a certain television series I've been doing and it's no different than any other from that series of done, matter of fact it's the last episode and all other until now have been perfect.

All of these issues were using the exact same settings in CCE as all the other perfect encodes CCE has produced for me. I'm going to try these encodes again, but anyone else get odd behaviour like this from CCE on occasion?

EDIT: I'm still getting these Avisynth errors if anyone can help!

Same result.... it encodes about 10 min. or so and then the rest of the video shows this:

Avisynth: caught an access violation at 0x0f0992d3, attempting to read from 0x0f4ab65f


I guess this is an Avisynth error? I'll go see if I can find this in another thread or something but if anyone has heard of this please enlighten me... I've done tons of encodes and never had this happen. If I drop it into virtualdub it errors and says there's no video frames in the file. If I import it into DVDLab it shows the first bit of the encode in the preview window and the rest displays this error message (in the video), that's how I got ahold of the actual error to begin with. Any help is appreciate, tia.

It sounds like either corrupt source or out of date codecs. I find the most reliable way to feed CCE is through avisynth, so CCE gets an uncompressed avi as source, regardless of the original codec. I would scan these particular avis for bad frames using virtualdub or divxfix, and make sure you have the latest version of the codec, especially if it is Xvid.

It's more likely that I am misunderstanding you than the other way around and I didn't specifically say it, but yes, I'm already using Avisynth and have been for quite some time.

The .avi in question is the last of 12 of a television series I picked up through a torrent. They are all identical as far as resolution, codecs, yadda yadda, and I'm using the exact same CCE settings and whatnot as I always do, which has worked perfectly on all 11 previous episodes. The only thing that would make any sense is bad frames in the .avi... which plays perfectly fine on the PC here.

I'm familiar with scanning sound files for bad frames and such, but maybe someone could throw me a link to something that will scan for bad video frames (and fix 'em if possible). If someone will just post a link I'll gladly take the time to read up on it.

DivxFix is a stand alone program for scanning and sometimes repairing. Just load and scan.

Virtualdub has a scan tool under the video menu.

I'm still getting these errors... I've checked everything under the sun it seems, I've got the newest versions of Avisynth and all the related codecs, etc. One of the encodes that didn't work before did work fine, but continuing on I get this error again... grrrr

I'm only using Avisourse, Lanczose resize and ConverToYUY2, from an original NTSC source with error free VBR MP3 sound, not that the sound matters at all. I'll go scan w/that Divxchecker mentioned but I'll be surprised if it fixes it.

Have you tried upgrading/reinstalling avisynth ?

[Pisces225]

Yes. Also, thanks for the replies!

At first I was indeed using a very old version, but have upgraded to 2.5 and still get the same errors. However, a scan in VDub revealed something like 13 'bad' frames and approx. 1400 'non-encodeable' frames. Sounds like my source is bad. The quality is about crap anyway with bitrate in the 1500 range. So I've basically written off that source material and it's really the only things I've had those specific problems with.

What's bothering me more at this point is my audio issues and having no sound in my VOBs after authoring... if anyone feels inclinded to give me a hand with my very odd experience I'd appreciate it. Here's my audio issue thread: https://www.videohelp.com/forum/viewtopic.php?t=273633
