Source underlying framerate - Conversion
hello, here I have a funny source I think I solved but output framerate comes to be a bit strange.
You better download the sample to understand, but I explain: source is interlaced NTSC, but only every other frame is a new frame, that is in fields: ab,ab,cd,cd... -so select odds: ab,cd,ef... -then bob and get NTSC 29.970 fps output with no dups. BUT, every 2 frames there is a bigger jump, just if the next had happened: ab,cd,gh,ij,mn... -so I frame interpolate those missing frames, and I get 44.955fps. What kind of framerate this is? It's not even near any standard... Code:
# NTSC 30fps source selectodd # to 15fps bob # back to 30fps InterFrame(Preset="Placebo",Tuning="Film",NewNum=60000,NewDen=1001,...) # to 60fps selectevery(4,2,3,4) # To 45 fps. Skip the no-gaps interpolated frames. http://www.mediafire.com/?722eb33nz5c3c6t Last edited by Dogway; 8th December 2011 at 11:32. |
