Suggestion to the DV Guide

[Boost]

By using a codec for DV and not relying on the direct show filter in Windows you can speed up things alot and also enable virtualdub, tmpgenc etc to read the files better.

Panasonic has a (free??) codec downloadable at
My homepage (http://fredrik.rambris.com/files/pdvcodec.zip)

also if you capture with f.ex. Microsoft MovieMaker you can't read the files with a lot of programs. The files need to be converted to (or was it from) type2 to 1. You can do that with a little program also availabe at

Nice Guide BB,but Im still playing with IVTC'ing alot since I got my Can-o-puss(and the Sopranos started)......rflol

My IVTC(and Im NTSC as well) runs like this....
# IVTC
#Telecide(order=0,guide=1).Decimate()
# or use
#IVTC(44,11,95)
#GreedyHMA(1,0,4,0,0,0,0,0)
#
#
# DEINTERLACING (1)
#FieldDeinterlace()
#FieldDeinterlace(blend=true)
#TomsMoComp(1,5,1)

Its the only way I can get a progressive picture without interlace
artifacts.

I load up GKnot,open the avi there,crop-resize,etc.
Add:ConvertToYV12(interlaced=true)

Save as a SVCD templated AVS from Gknot and encode.

ANd I use about 512x384 as the re-size BEFORE setting it as 480x480.

Looks soft(because of the blend),but it is proggresive...
:cool:

Cheers and thanks again BB!!

More speed with the Panasonic codec (which you can download from the "Links" sticky here by the way)? I really doubt that, because the Panasonic codec has the same codebase as Microsoft's DirectShow filter, but it outputs to RGB. So if you want to be fast, I believe it's better to stay in the YUY2 colorspace as long as the encoder supports that as input.

Thank you for the hint with the converter. There are free converters listed in the "Links" sticky thread, too, but I didn't have your on the list. Where does it originate from? May I add it for redistribution?

@Morbo:
Thank you for the hints. I don't have much experience with NTSC, because I live in a PAL country, and I have a PAL camcorder. What I know about NTSC mostly originates from posts here in Doom9's forums.

Why do you need to IVTC? I believe it's better to stay at 29.97 fps instead of decreasing the framerate, which is typically done for film captures (originally filmed @ 24 fps, but telecined to 29.97 fps).

Regarding the deinterlacing step (if you really want to do that), I had the impression that there's not much difference between NTSC and PAL.

I experienced that when seeking with the DirectShow filter it was utterly slow. And when opening in VirtualDub I got a no codec error. The panasonic codec enabled me to use VirtualDub.

No idea where I got it from. But I beleive that it's freely distributable.

Boost,
you can open the video in VirtualDub through AviSynth via DirectShow (DirectShowSource command); but if you want to open your DV AVI directly in VirtualDub, you need a VfW DV codec, because VirtualDub is a VfW application.

If I remember correctly, DirectShow seeking has been improved in the latest AviSynth versions. Which version do you have?

AAaa... so it was an AviSynth bug! I can't remember which version I had and I haven't done any DV processing for a while now. Nevertheless. A VfW DV codec is A Nice Thing to have :D .
