View Full Version : Does TMPG has option: 2:2 pulldown when playback for PAL

I'm doing PAL DV to DVD conversion.
I noted that the quality of DVD is much inferior if input interlace source to TMPG and encode with interlace mode. The quality can be much improved at the same bitrate by inputting deinterlaced DV movies.
Converting deinterlaced movies by TMPG will give progressive scan DVD but I prefer interlaced DVD which will give smoother pictures (50 fields/sec rather than 25fps), especially on TV.
For NTSC DV, there is an option (3:2 pulldown when playback) if I can convert the DV to progressive and fps to 23.976 using Avisynth.
How about for PAL DV? any 2:2 pulldown when playback?

Please correct me if something wrong.

2:2 would be the same as 1:1 which is the same frame rate as the original so I'm not sure what you mean. Anyway pulldown is not used in PAL.

What you can do is following:
Deinterlace to 25 fps progressive
Slow down the frame rate to 23.976 fps and resize to NTSC 720x480.
Encode with 3:2 pulldown at playback.

But you'll loose some smoothness because of the deinterlacing.
A suggest taking a look on this tread on how to do this conversion properly in avisynth and keeping the interlaced format: http://forum.doom9.org/showthread.php?s=&threadid=35387

You need higher bitrate to get the same quality when encoding interlaced. I suggest using 6000 kbit/s VBR or 8000 kbit/s CBR.

If you have deinterlaced your dv material the smoothness (50 fields) is gone, no way to get it back.

Thanks.
ronnylov, the thread you posted is not quite easy to understand as I've just learnt avisynth for few days.
I'll try this when back home.
I've learnt a lot from that thread.
