Using VirtualDub and filters

[wilsok]

I am moving some older video8 video to DVD. I have captured the video in Mpeg2 format to my computer. I have completed the cutting and joining with VideoReDo. I read on the forum that I could use VirtualDub plus DotCrawl to clean up the video, which appears to do the job. The final Mpeg file I am working with is 3.5 gig and the problem I am having is that the output from virtualDub is over 100 gig and the program stops afte it reaches 4 gig. Please tell me how to correct this. Thanks for your help

You are aware the VD only outputs AVI type formats? You would need to encode again to MPEG-2 if your final destination is to a DVD. That will result in some quality loss. Which VD are you using? VD Mod or VD MPEG-2 would be needed for a MPEG input.

That said, in VD you have to choose an output codec or it defaults to Uncompressed RGB, which will be huge. But since you need to encode again to MPEG-2, you could frameserve the output directly to an encoder like TMPGEnc encoder and avoid your in-between AVI output file. https://www.videohelp.com/virtualdubframeserve.htm This will save hard drive space and time. Not all filters work with frameserving, so do a test frameserve and encode of a short clip.

Or you can pick a lossless codec like HuffyUV to output from VD, but you will still have a large file. I usually try to do the original capture in a AVI type format such as HuffyUV or DV and process that through VirtualDub first, then convert the filtered file to MPEG-2. That results in less loss to quality.

And welcome to our forums.

You need to use the frameserving feature in vdub / vmod to send it to an mpeg encoder like bbmpeg .

There is also a possible method using avisynth , and create a script which can be loaded via bbmpeg or quenc for re-encoding to mpeg / mpeg2 .

4 gig is the max file limit under fat32 formatted hard drive's .

Hi wilsok,

Welcome to the forums.

I am moving some older video8 video to DVD. I have captured the video in Mpeg2 format to my computer.

You'd be better off capturing to DV AVI (or similar) as MPEG isn't designed to be tinkered with - it's designed as an "end product" format. You're wanting to apply filters etc. - DV AVI is much better suited to this over MPEG.

I have completed the cutting and joining with VideoReDo.

If you do decide to recapture to DV AVI, you can use VirtualDub for simple cutting and joining.

The final Mpeg file I am working with is 3.5 gig and the problem I am having is that the output from virtualDub is over 100 gig and the program stops afte it reaches 4 gig.

VirtualDub, unless you tell it otherwise, saves to uncompressed video by default - explaining your 100Gb file size. To change (assuming you go the DV AVI route):

1) If you haven't got it already, download and install the Panasonic DV Codec. There's install instructions on the download site.

2) In VirtualDub, click: Video -> Compression then select Panasonic DV Codec.

3) Add filters as desired.

4) Click: Video -> Full Processing mode

Then save as AVI and it'll be in DV AVI format. VirtualDub (or any of its variants) does not save to MPEG, even if the source is MPEG. So you'll always get an AVI from VirtualDub.

The 4Gb issue might be because your file system on your PC is FAT32 and not NTFS.

Or, better still, carry on posting in this thread (or in the forums in general) and everyone can see it meaning you have access to more than just Bjs' knowledge. It also benefits others if they have the same, or similar problem, as you - they can search the forum, find your post(s) and get the answer. That can't be done with Private Messages.

Thanks for the quick response. The capture card I used was WinTV-PVR-350 which saved the file to an Mpeg 2 file format. That worked great for using VideoReDo to edit the parts and join into the final Mpeg file. I did not want to mess with converting the files back and forth because of the possibillity of quality loss. The Quality is OK but not great to start with. Both VD mod and VD mpeg-2 would accept the file. I read on the forum that someone who does this same thing used DotCrawl filter and I thought I would try that. I am also trying TPMGEnc with a simular filter built into it. That program saves the file as an Mpeg 2 file at the size I choose. It takes a couple of hours to do though and I am in the middle of that now. I'll see how that turns out. If That does not do the trick, I'll try your suggestion.
