Getting something to work for M2V!!

[llamatronique]

Can you make available for downloading a source M2V that you claim DVD2AVIdg/MPEG2DEC3dg invents frames with? I'd be happy to analyze it and tell you what is happening.

Oops, I accidentally hit edit instead of quote and since I'm a mod in this forum, that overwrote your post. Sorry. Please repost it.

Thanks Neuron...

I did 30 secs of PAL bars/tone from 00:00:00 to 00:29:24 with burnt in TC.

Having a look in vdub... at times the tcburn clocks forwards while the position is being moved backwards ;) Cinemacraft reports 1004 frames for this one ;)

hehe.. i had it in notepad a few minutes ago but i closed it.

something like.

FCP->m2v->dvd2avi->mpeg2dec3->ccebasic

produces erratic framecount, often more than expected framecount.

mpegdecoder does the same thing btw.

FCP->m2v->directshowsource->ccebasic

one machine seems to be working ok (correct framecount on one machine), but another will not encode, reporting what looks to be an error, but encodes only black. playing in mplayer2 though is fine and reports no error.

... ok, I hadn't noticed your v1.1. I'm getting bang on 750 frames at 00:29:24 now. I'll put it in my setup and see how it fares on a batch job.

Cinemacraft is still being funny about the duration (1403), and it encodes the last frame for between 750 and 1403, but I'm calculating the ecl encode length from the audio source so i might get it to work ;)

Nope, can't make it work. I realised my avs scripts use FrameCount for some compositing...

Sometimes it appears to be frame accurate, and others it's quite erratic (I think the more I seek, the more it drifts)... almost always it returns a clip longer than the source.

My dvd2avi switches are pretty basic...

-IF=[source.m2v] -OF=[dest] -exit

avs script is now :

LoadPlugin("C:\Program Files\AviSynth 2.5\Plugins\MPEG2Dec3dg.dll")
MPEGSource("barstone_30sec_tcburn.d2v").ConvertToYUY2
Info()

Info() I'll have a look at the M2V but there is a problem right here. You're not using the MPEG2DEC3dg DLL for decoding! You have to have this (note the 2):

MPEG2Source("barstone_30sec_tcburn.d2v") # see help file

Try that and report back.

EDIT: I got the file and used DVD2AVIdg/MPEG2DEC3dg and I can't duplicate your issue. But I don't have CCE. Anyway, as I said please try using MPEG2Source() and report back.

Ahhh... (lightbulb).

I was hoping FCP/Compressor wasn't the problem - although the aif export in compressor is full of bugs, so I entertained the thought.

Ok, I'll give that a try. Thanks a million.

Perfect.
