View Full Version : NTSC<->PAL format conversion in 2009

Hello everyone,

i have a NTSC tape (betacam sp). I digitized it and used procoder to convert it to PAL (all interlaced). It looks good and encoding speed was okay (about 12fps).
I googled and searched the forum to find a good avisynth-based solution to do the format-conversion. I found threads from 2003 and scripts that use "old" deinterlacers.
I tried a few (MCBob+ChangeMCFPS, MCBob+changefps, and some others).
But we live in 2009 now, i think there are new ways to do it (new deinterlacers, MT-stuff, GPU, new versions of mvtools and other plugins, ...). So any tips for fast, modern and artefact-free(!) format-conversion scripts?

give NTSCtools a try, though it's possible that it's broken on most machines (very hard to debug as it works on all the machines i try it on). the last post in the thread has the minimum of plugins you need and their versions/dates.

other than that you could try a terranex or a snell and willcox ph.c... little bit pricey though.

what's the content of this SP tape? is it a camera tape or does it contain film originated stuff? if it's just a camera tape (no doubt it's interlaced, as most cameras with progressive mode are a lot newer than betaSP), you should be able to just yadifmod and mvtools or motionprotectedfps of my variant of motionprotectedfps. i'm guessing the material wont be too challenging.

procoder does a pretty good job too though. fine for most domestic CRTs unless motion is very fast, or moving details need to be legible (like credits and news-tickers).

There are a couple of steps in doing a standards conversion.

1) Bob-Deinterlacing
2) Scaling
3) Frame-rate conversion

1 - I suggest any of the most up-to-date deinterlacers - MCBob, TempGaussMC, etc... YadifMOD with NNEDI is a great bobber that's not too slow, per Mug's suggestions.
2 - Spline36 is my usual resizer of choice. Use whatever works...
3 - Here's where things get interesting. Mug's suggestions are again quite good here.
