Really need help with framerate and such....

jediphoenix · Post by **jediphoenix** » Wed Mar 30, 2005 7:28 pm

I followed the steps (most of them...) from Absolute Destiny's guide, and somehow my framerate ended up being 19.181.....I don't know what went wrong. I have my frame size as 640 x 480, and I used the script editor to 'decomb'...don't know if it worked. My decompressor is Lagarith lossless codec.
I'd like to import it into adobe premiere, but like I said, the framerate is wonky....any help would be much appreciated.

Sounds like you applied IVTC (or at least Decimate) twice.

29.97 * 0.8 * 0.8 = 19.1808

(0.8 standing for a typical Decimate-cycle, where every 5th out of 5 frames is thrown away)

I was going to use smartdecimate this time instead of decomb, and see if it works.

can I use decomb and smartdecimate, or should I only use one?

If the question is "can I use DECIMATE and SmartDecimate", then the answer is no -- you should only use one.

Decimate isn't all there is to the Decomb package. There's Telecide as well.
If all you do is SmartDecimate, that won't remove the interlacing.

so I should use smartdecimate and telecide as well?

Also, I'm just a bit confused by this step:

Keep DVD Resolution and PAR

You can edit at full dvd resolution if you like (720x480 for NTSC and 720x576 for PAL) but any graphics you make for your video (like text etc.) will be at a different Pixel Aspect Ratio. To compensate do this:

NTSC Graphics: Make images at 720x528 and resize to 720x480 to have DVD PAR.

But it said previously to have it at 640x480, so that's what I put it as, in the script editor as:

LanczosResize(640,480)

Is there anything else I should do?

And sorry for the second reply (can't edit posts? too bad....),
but my telecide order is 1....and using the guide, it says I should know what it should be by analyzing it, but I couldn't figure what it should be at all.

Can you post your whole script? It'd make things easier for everyone.

mpeg2source("C:\Paradise\Paradise.d2v",cpu=4,upconv=true)
SmartDecimate(24,60)
AssumeFPS(24)
LanczosResize(640,480)
Telecide(order=1,guide=1)

You have so much stuff there in the wrong order, I don't even know where to begin.
Let's just say the proper order is more like:
source line
Telecide
decimator (decimate or smart decimate)
(any cleaning)
resize
fps adjustment

assuming your footage is top field first, like your script indicates, give this a try instead:

mpeg2source("C:\Paradise\Paradise.d2v",cpu=4)
Telecide(order=1,guide=1)
Decimate(cycle=5, mode=2)
LanczosResize(640,480)
ConvertToRGB32()
AssumeFPS(24)

Hopefully you'll get 24 fps IVTC'd footage from that.
