Okay, so I made a new script in GK

Ditch GK, your script is way to cluttered for what you are doing, M also said to ditch it, but you still use it, we can't help if you don't use our suggestions.

Yeah, maybe finish reading the rest of the post first? I ask specifically for that clarification since M's post could be read 2 ways.

So, how does one get an AVS script without using GK?

So presumably I write my own avs script in notepad? Is there a guide I can follow for that? I wouldn't know where to begin in writing an avs script. I'm also curious what the point of AVIsynth is if it's better to just write the script yourself.

what exactly are you wanting to do to your avi file?

I just need to create a lossless avi file from my M2V file so I can start editing in Vegas.

You misunderstand what Avisynth is.  Avisynth is a frameserver program.  You write the script for Avisynth.

Once you have loaded your m2v into DGIndex, you save as a d2v.  Then write a script pointing to the location of the d2v on your hard drive.

Mpeg2Source("Your_Directory_Structure\Your_Filename.d2v")

Open that script in Virtualdub.  Then:

Video-->Compression-->Lagarith lossless codec

(Install lagarith  if you haven't already)

File-->Save As-->AVI

Rendering might take a while.

EDIT: Vegas requires RGB.  If you use Full Processing Mode (under the video tab), your AVI will be converted to RGB.  I don't use Vegas, so I don't know what kind of RGB it is best to work with in Vegas.  If I were you, I would find this out, add a line to the script to make Avisynth convert to that from of RGB and use Fast Recompress (under the video tab).

Sweet Merciful Shatner! I think it's actually going to work this time around! I have my fingers crossed. I'll report back in about 45 minutes when it's done rendering.

Lol!  I hope it works.  I take it you selected Forced Film for Field Operation In DGIndex.

Yup, forced film in DGindex. I think if this all works out I might post a step by step just for Ripping to lossless AVI to help those as clueless as me ;)

I`m getting a little anxious as the projected file size of my AVI is considerably smaller than I would have anticipated...

How big is the projected size?  Are you converting a whole movie or just clips?

Author

I was converting the whole movie. Previous AVI efforts landed me over 100 gigs, this AVI is 47 gigs. Also, the AVI I get can`t be played on VLC, it apparently doesn't support LAGS:

No suitable decoder module:

VLC does not support the audio or video format "LAGS". Unfortunately there is no way for you to fix this.

 

That doesn't bother me much, it plays fine in Mediaplayer and it looks very nice, no interlacing. One other thing that concerns me though is aspect ratio. It looks fine, but when I view it in fullscreen on my 16:9 display I get pillar boxes in addition to letterboxing. I would expect an anamorphic image to fill the screen side to side.

 

So what have I done wrong this time? ;)

That file size is about right.  I would imagine that your previous efforts were uncompressed AVI.  Using lagarith allows you to create a lossless file that is considerably smaller than an uncompressed one.

VLC always gives that message.  You don't play massive lossless AVIs in VLC.  If you need to preview, do so in Virtualdub.

If your transfer takes nominal analogue blanking into account, you might expect to see thin pillarboxing of up to eight pixels in width, on the left and the right.  If that's all you see, then it's normal and you have done nothing wrong.

Incidentally, if your picture looks slightly squished, it is because you are viewing a 720x480 image without the 16:9 DAR that stretches an anamorphic encoded image back to the right size upon playback.  Don't worry about this.  You add the 16:9 DAR on re-encoding.

I think those sizes are kind of big myself, my V3 lossless avi files range from 22-25 GB's in size with Lagarith, and Windows Mediaplayer will play those files, I use that and VDub for testing and going over.

My Ep I Lagarith file is 50 GB.  I seem to remember boon's editing with Vegas guide saying typical size is around 20-25 GB per hour, which fits with what I have.

Yes; it depends.  Mine have ranged from 18GB to over 50GB.

Hmm, My pillar boxing is significant. Here's a screencap of mediaplayer playing the AVI in fullscreen mode:

Versus how it displays fullscreen from the DVD:

 

Hmmmm...

^^ Stop using a media player to preview AVIs.  For one thing it doesn't have a DAR to correct the image.  Load the video into Virtualdub.

Video-->Copy sourceframe to clipboard

Then paste it into Photoshop and make a picture and we can see how it looks.

EDIT:  I actually use Virtualdubmod because it has a snapshot function, under the video tab, that Virtualdub does not seem to have.

Alrighty, here's the snapshot from vdubmod:

So I guess it's all good eh?

Let us hope that the quality of the snapshot will be indicative of the quality of my edit. ;)

That is going to depend greatly on how you encode it and with what encoder you use, is the finish project going to be an avi or a DVD?
