I am likely committing another drastic newbie mistake...

I've been following all the guides and instructions, using MovieStacker to create an .avs file and calculating the filesize etc.

When I encode the sample in TMPGEnc, I am always getting a 498K file... whether I raise or lower the CQ, or change source files... even when I used a 1.3GB source! I tried to watch the 498K file and it was a split second of black.

What could I be doing wrong? Is it possible that avisynth is not serving the file properly to TMPGEnc?

thanks,
gosens

Here is the script. It is the same for this 1.3GB mpeg2 "quebec test" as for the 40MB mpeg2 "alf test" except of course for the filename reference.

#================================================= =====#
# -= AviSynth script by MovieStacker v2.0.0 (beta3) =- #

LoadPlugin("E:\TV\MovieStacker\Filters\MPEG2Dec.dl l")
LoadPlugin("E:\TV\MovieStacker\Filters\DustV5.dll" )
LoadPlugin("E:\TV\MovieStacker\Filters\UnFilter.dl l")
LoadPlugin("E:\TV\MovieStacker\Filters\LegalClip.d ll")
LoadPlugin("E:\TV\MovieStacker\Filters\Sampler.dll ")

Mpeg2Source("L:\PVR\test project\quebec test.d2v")

Sampler(length=18)
## MPEG size = ((Total frames/MovieTimeInMinutes)/24) * MPEG sample file size * .98 ##

Are you sure the encoded clip is only black ?

Do you have any MPEG2 decoder installed on you PC ? Because I wonder if the clip is in fact a error message, but you can't see it has you don't have a MPEG2 codec installed (or MPEG1 if your encode in MPEG1 of course).

Let me guess : sample length is exactly 10 seconds ?

I definitely have all the mpeg-2 codecs necessary. My source files are mpeg-2 and they all play fine, and I've encoded with tmpgenc before and seen the video correctly.

This is my first time using an .avs file. I'm using it first to create a sample as described in vmesquita's guides. The sample - regardless of my source and regardless of the CQ setting - always creates a 498K clip, all black, duration less than a second (0:00). Plays in various players and shows the same thing.

This is why I'm wondering if it's my script, or if avisynth is not working properly as the frameserver. I have the DirectShow piece installed which I understand is necessary for frameserving mpeg2's as well as readAVS etc.

Just ran the scripts again. When it encodes the sample I do not see any images or frames coming through the viewer in tmpgenc, it's black there too. Here's the results message:

Start: 31/10/2003 12:02:14 AM

Result: Succeeded

It's always 8 seconds to complete.

Did you try to reinstall TMPGenc?

Try to open the script in VirtualDub and see what you get.
