PAL 1080p to PAL 576i with high quality motion compensated interpolation
I have a (legal) 1080p source of sports footage in an mp4 container. I only have a DVD player and an old simple media player. Sports footage looks better interlaced anyway (I once heard it called "motion fluidity").
I can use Mr Donald Graft's dgdecodeNV to make use of my Ti750i graphics card to resize the 1080p input to 576p apparently like Code:
LoadPlugin("C:\DGindex\DGDecodeNV.dll") DGSource("footy.dgi",resize_w=720,resize_h=576) (i) double the framerate using the latest nice accurate form of motion compensated interpolation (something in mvtools2?) (ii) and turn that into a DVD compatible TFF interlaced fields 576i (ie 50 fields/sec) output. Suggestions very much welcomed on how to do (i) and (ii). edit: for (ii) I think this turns 576p50 into 576i TFF interlaced Code:
AssumeTFF() SeparateFields() SelectEvery(4,0,3) # top field first Weave() Code:
#To double fps with MFlowFps for 'best' results (but slower processing): super = MSuper(pel=2) # Use block overlap, halfpixel accuracy and Exhaustive search backward_vec = MAnalyse(super, overlap=4, isb = true, search=3) forward_vec = MAnalyse(super, overlap=4, isb = false, search=3) MFlowFps(super, backward_vec, forward_vec, num=2*FramerateNumerator(last), den=FramerateDenominator(last)) http://forum.doom9.org/showthread.php?t=164554 Last edited by hydra3333; 9th September 2015 at 06:02. |
