WTK: Frameserving-- avisynth or Vdub

[TaranScorp]

When I capture a two hour tape to HD I get a 56gb file. If I convert using Tmpeg I run out of room on my hard drive(110GB). So do I frameserve from Vdub or Avisynth to eliminate the extra file so I do not run out of HD space and which is preferred to frameserve from? I have a 56gb Huff AVI that is 640x480 interlace from a NTSC VHS source. In Tmpeg I'm going down to 340x480 video only.

If you're capturing, opening the AVI and editing it, and then saving the edited movie back out as an AVI, then frameserving will eliminate the need to create that second AVI file.

Avisynth and VirtualDub can both frameserve in to tmpgenc. avisynth is faster, virtualdub is easier to use. I think each can do something that the other can't easily do, but both are capable of performing most typical editing tasks.

Well, I have a 56gb AVI file after capturing a 2 hour VHS home tape, I used Huff codec, now if I want to encode with Tmpeg, Tmpeg will create another file befor creating the M2v compressed file which causes me to run out of hard drive space, if I frameserve from VDub to Tmpeg, will it eliminate Tmpeg making another huge file before creating the M2v file?

Oh, misunderstood what kind of problem you were having. If tmpgenc is creating a huge file it's probably a temp file. I'm assuming that you're using 2-pass VBR, since I think that's the only way you'd end up with a huge temp file.

If you're running out of space you can point tmpgenc at a different drive for its temp space (in environmental settings). Also check under the CPU tab in the environment dialog and disable the setting for keeping the cached video if it's enabled (I don't remember the exact name of the setting). That setting speeds up encoding by keeping the results of the first pass, but might use lots of disk space.

I'm not sure what else might cause a huge temp file. If you're using an external audio tool tmpgenc will write the audio out to a wave file in the temp directory, for 2hrs that would be a pretty big file, but it deletes the file as soon as it's finished with it.
