Script fps and when to convert fps

Postby squirle » Thu Nov 16, 2006 3:14 pm

At the moment im trying to figure out how to get the footage in the desired settings for and amv competition, but im lost when it comes to the framerate.

The source is PAL interlaced (wings of Honneamise, mangadvd,2)
Preprocessing avisynth

Code: Select all

loadplugin("C:\Documents and Settings\victor\Desktop\dgmpgdec148\DGDecode.dll")
Loadplugin("C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll")
MPEG2Source("G:\wings\video\VTS_08_PGC_01_1.d2v",ipp=true,info=3)
ConvertToYV12()
Telecide(order=1,guide=0,post=4,vthresh=50)
Decimate(cycle=5,mode=2,quality=3)
ConvertToRGB32()

This leaves me with a 20 fps avi. And i believe premiere should be 24 to prevent problems.
And the required settings for the competition are NTSC format. MPEG2, 720*480 or 704*480 (29,976 right)

Now im lost as to what script to use pre-processing or when/what to do post-processing. Am i missing something in the guides. Cause i can't get my head around it.

You can add the line

AssumeFPS(24)

for 24fps footage but if the con wants 29.97, to save a LOT of time just use

AssumeFPS(29.97) and edit with the faster footage.

Don't IVTC PAL footage!
Please read the guide carefully. http://www.animemusicvideos.org/guides/ ... etb3a.html

To make a long story short, change Telecide() to

Code: Select all

Telecide(order=1,guide=2)     
#1 for Top Field First or Telecide(order=0) for Bottom.

And get rid of the Decimate() line. This should give you progressive 25 fps footage.

If you still get interlaced frames, then you need to read further down on the EADFAG page that Zarxrax linked to on using other deinterlacers.

Premiere should handle 25 fps footage like a champ. It's 23.976 fps stuff it can't wrap its head around correctly.

If you want to restore the original 24 fps film frame rate from 25 fps PAL sources, its a lot tougher.
