Conversion error but dont know why??

[TheLostTimberwolf]

I am using downloaded Divx 4 movies for conversion (so I know its already dodgey to start with for a svcd conversion)

Anyway, when I first tried to convert the movie to SVCD, the resulting movie played fine for the first 30 mins or so then, I got a black screen with the words in effect of AVISynth could not decode frame #xxx. The AVI format played fine on My pc though.

I read around a bit and found that this is due to bad frames within the movie itself, a bit more reading brought me to virtualdub, learning that virtualdub cleaned up such bad frames when the movie was saved in a direct stream copy. I checked the original AVI for errors and it found some, then I saved as a direct stream copy(audio and video) using Virtualdub, opened the newly saved avi movie into virtualdub and found that it had no bad frames now after the check

yipeee I thought, but after a re-encode of the 'fixed' movie I still ended up with the same error AVISynth cannot decompress frame #xxx.

I havent been able to find anything in regards to fixing this sort of error, or what is causing it, so Im asking for help here,

any ideas from anyone on maybe whats wrong or how it can/if can be fixed?

thanks for your time,

Why are you using Avisynth? Can you not load the avi directly into TMPG?

[TheLostTimberwolf]

TMPGEnc just crashes around the point were I assume the error is, I use DVD2SVCD to convert My files, DVD2SVCD uses AVISynth as frameserving, thus the use of AVISynth

Scan the avi for bad frames and remove them. Search the site/forums for how to do this.

[banjazzer]

Why don't you load the cleaned-up avi directly into TMPG with a VCD or SVCD template? For whatever reason, DVD2SVCD doesn't seem able to cope - although I presume it also uses TMPG as encoder. (Yes, I know DVD2SVCD can use CCE).

Basically, I don't really see the need to frameserve when TMPG can directly accept avis....unless you are using CCE, in which case if you have removed the bad frames I don't see why you are still getting an error.

[TheLostTimberwolf]

I see the point your making, using avisynth to work on an avi file is kinda like double handling.

Ill run the cleaned up version through tmpgenc and see how it goes,and return the results, i as do you fail to see why a file that after scanning shows no bad frames still somehow has them, lol.

Oh well cheers for the input banjazzer,

Ill be right back, after this conversion :P

I generally have'nt had too much luck "cleaning up" a bad framed movie.
As long as its not much more tghan a couple of hundred frames then a removal of bad frames (using this version of Virtualdub)does the trick.

Scroll down to the "Mp3_Freeze" version.
This version will scan for the bad frames and you can view them in Notepad ...then you can remove them with Virtualdub and re-stream the movie.

well as i sit here typing this im watching a properly converted SVCD, of the movie. Im still confused as to why it worked but I dont Care :P lol.

Seems TMPGEnc is the victor here CCE just couldnt cut it lol.

Ok thanks for all the help guys

Byeeeee

If you still want to use CCE, you could try saving the project file from TMPG, converting to a pseudo-avi with VFAPV Converter and encoding with CCE. The first two steps take a matter of minutes.

[TheLostTimberwolf]

ok, Ive found the converter( I think) however its use is somewhat lost on Me

Do I convert it from a stand alone program or is it done through tmpgenc ? or other lol

You proceed exactly as if using TMPG to encode, but save a project file (.tpr). You load this into VFAPI Converter using the *add file* button. Then hit convert to produce the pseudo-avi. This takes a few seconds to a minute, depending on whether you are including the audio.

Remember when you install VFAPI to run vifpset.bat first, or else it won't work. You'll find it in the Tools section called VFAPI Reader.
