CCE conversion crashes...why?

[aussiemac]

I have done many conversions of avis to DVD using the following.

Use FitCD to output an avisynth script to feed to CCE SP 267.

I check the avi using GSpot...for length ...frame rate ...and audio type.

So when I feed this particular AVI...which
is a progressive xvid with 5.1 ac3 and framerate of 23.976

via an avisynth script from FitCD to CCE 267

it goes thru successfully the initial analysis run ...but then breaks down
somewhere during the encoding phase.
I am left with a VAF file and a small MPEG file(about 2mB)

The original Xvid was in two parts which I joined with VirtualdubMod.

After joining I checked to make sure the join had worked okay by
viewing with MPC 6.4.9.0 ...in particular the area around where the
two parts joined ...seemed fine.

From GSpot this is one thing I was concerned with ...because it has AC3 audio
..under Container area
OpenDML (AVI v2.0)
DivX Style "packed bitstream" AVI
Interleave: 1 vid frame (42 ms), preload=512
Audio frames: Split across interleaves


Should it be something different...because of the AC3 sound.
This would only really concern the audio anyway ...so it shouldnt
affect the encoding of the video part ...to DVD??

I am looking for reasons why my CCE encode is crashing ??

Any suggestions???

It is better not to join the AVI files and treat them as separate files. They can be easily joined aferwards (after encoding to MPEG-2) and this can be done either before or during the DVD authoring stage.

Also you might want to add the NO AUDIO parameter to your AviSynth script. To do this just add , false to the end of the line that loads the AVI file.

For instance:

AVISource("C:\downloads\filename.avi", false)

That cancels out the audio which you don't need if you are using CCE and have AC-3 audio in the original file.

Thanks...I normally do add this ...false...bit to the script.
I must admit i had forgotten why i was doing this...I always untick
the audio part in CCE as well.

What do use to join the two parts together once you have encoded
both parts to MPEG2??

I use DVDLab pro to author all my DVDs

If you really need to join, you can use AVISynth directly:
AVISource("d:\firstpart.avi") + AVISource("d:\secondpart.avi")
Many ways to skin a cat.
But really, FulciLives is correct - best is not to join at all.

I use DVDLab pro to author all my DVDs

I use MPEG-VCR to mux and join the two parts.

What I do is take the video from the 1st file and and mux it with it's AC-3 file ... then I take the video from the 2nd file and mux it with it's AC-3 file ... I use MPEG-VCR to do that. It has a multiplexer and de-multiplexer built-in.

So I now have two complete parts ... both with muxed AC-3 audio.

I then join them with MPEG-VCR

I've heard some other users mention MUXMAN as a good program for multiplexing and it is freeware so that is how you can get the two muxed files.

As for joining I'm not sure what to use that would be freeware but I know MPEG-VCR works well.

In the past whenever I tried to join two AVI files with AviSynth I always had A/V sync issues after the join part.

So I gave up on it.

Then I read that there is more than one way to do it with AviSynth and that one way could lead to A/V sync loss and the other way should not ... and here I think I had been using the "wrong" way.

But still I never bothered again with it.

Also since it is AC-3 audio ... I think that makes it even more "iffy" and therefore best to treat the two AVI files as separate files up to the DVD authoring stage of the process.

Thanks for this...I know this program....

looks like this avi will have to remain so...just an avi...unfortunately
i have thrown away the two parts...

Still ...appreciate your quick response!!

I'll have to assume that the avi is somehow corrupt ...so CCE
doesnt like it...mystery unsolved

After joining the two avi files I use direct stream copy on the video and audio to a new avi then I use avidemux to seperate the audio and video then fitcd for the script to feed to cce and the I use tda if you use dlp just feed the mpv and the ac3 in and you get your dvd thats for 5.1 ac3 for anything else I use ffmpeggui to extract any audio to 2 channel ac3 file and I have so far had no sync problems

[aussiemac]

Well folks ....I have success....and I'm still no closer shedding
light on why!

I managed to do a four pass CCE encode last night on my problem
avi !!....so... much fist pumping and... yes!! After three days of trying various
ways...finally its done!

I thought I would give ...kosz's suggestion a go...and re-output the avi
via VirtualdubMod(directstreamcopy) ....then I made sure I had added

as FulciLives suggested....AVISource("C:\downloads\filename.avi" , false)
the bit in Avisynth script to cancel out the audio from being encoded.
Thats because the avi has 5.1 ac3 sound ...which I would demux and use.

Then I had had a problem once before with some junk at the end of an avi
causing problems...so just for luck I added a trim into the script as follows

AVISource("D:\avi\xxxx.avi",false)
LanczosResize(688,352,0,1,640,270)
AddBorders(16,64,16,64)
Trim(0,180393).FadeOut(150)
ConvertToYUY2() # For VirtualDub or CCE

so if there was junk at end causing CCE to hiccup...then this might help.

Anyway whatever the problem was ... I still dont know ...I have my encode
and ...well ...just a note to say Thanks for the tips and suggestions!
