AVI 576x320 23.976fps -> DVD

[AlanHK]

As title, I have an AVI file: 576x320 23.976fps which I want to convert to MPEG to burn to DVD. I can play either PAL or NTSC. I gather that 23.976 is NTSC, so probably NTSC would be cleaner.

I've made a few DVDs using PAL AVIs, using HCenc via an AVS script.
However, when I try this script:

AVISource("226.avi").FastBilinearResize (720, 480)

HCenc complains:
"Warning: frame rate not DVD compliant; resolution not DVD compliant."

I guess that I need to convert the frame rate to 29.97.
I've found several Aviscript functions concerning framerate, but am not sure which to use.
(I don't understand however why it complains about resolution, 720x480 should be NTSC; and I also tried 720x576, PAL, with the same result, but I can revisit that after framerate is fixed if it's still a problem.)

Can anyone advise the AVS script to make this work?

23.976 is a compliant framerate, so long as 2:3 pulldown is applied before authoring.

I haven't used HCEnc, so I'm not sure what it is complaining about. Perhaps the framerate isn't 23.976, or perhaps some other setting is conflicting.

Try getting FitCD to create a basic script for you, and try that instead.

Hi-

I've never heard of FastBilinearResize. If it exists, maybe you have to load a .dll. Not sure. So, I suspect it's not being used, which would account for the error message. Bilinear is crappy anyway. Try:

AVISource("226.avi").LanczosResize (720, 480)

Or some BicubicResize. Much better resizers.

You also understand that a direct resizing from 576 x 320 to 720 x 480 will give you a distorted output ? You should actually be resizing to 720 x 368, then adding borders to 480, if you want 4:3 letterboxed.

Try this instead, for a 4:3 letterboxed output

AVISource("226.avi")
Lanczos4Resize(720,368,3,0,570,320)
AddBorders(0,56,0,56)

I do have the dlls; it may not be the best, but it certainly works, I've done several files using it, and I can use the avs with Virtualdub.

-- I found an "advanced" setting in HCEnc to apply 3:2 pulldown -- no warnings now.
Thanks. (HCEnc seems to have everything, except documentation.)

I'll check out various resize functions later.

Oh, so it does exist? Learn something every day. Glad you got it going OK.
