Deinterlace 1920i @ 25fps -> 1920p @ 50fps

[koopa]

Hi, I have been trawling these forums to no avail, and would love some help / discussion on this matter:

Like a lot of the people on these forums, I have deinterlaced by converting to 25 (or 30) fps for TV shows, but have come to appreciate the fluidity of 50fps motion. I am fairly competent with AVS workflows (sufficient to do IVTC and create a VFR MP4 of Anime).

Right now, the only method I have of performing weighted interpolation of an interlaced stream -> progressive -> MP4 is to use TMPGenc, and although TMPGenc is a GREAT program, its VC-1 (WMV) and x264 compression leave a little to be desired (need very high bitrates to not macroblock in hidef material as compared to MeGui / x264 - Slow).

Now I would be happy to either:
1) Encode preserving interlace
or
2) Motion Compensate Deinterlace to 50/60fps

But I am after the best possible compression, and I have NOT been able to get very good compression ratios for interlaced material compared to 50/60p of the same material.

So please, someone, tell me what line to add / program to download to be able to MCDeint within the AVS system to save me creating 200Gb intermediate HUFFYYUVs from TMPGenc...

Thanks!

Try my program, ASXGui, with these settings: (making sure you have the right field order)

Here's my 2 cents:

1) Bob deinterlace in AviSynth with TDeint+TMM+NNEDI (if you can stomach the speed ;) otherwise just YADIF)
2) Encode using MeGUI

The process is slow for a reason. Deinterlacing 1080i and then encoding it using x264 is not an easy task! It's a huge amount of data!

One thing to consider is that a lot of broadcast 1080i doesn't even deserve 1080 lines of resolution. I find that 720p60 is more than enough for these sources (sometimes, not always).

Well my program uses the avisynth plugin "DGbob" which was written for this very specific purpose. And using it all together in one GUI makes things much simpler and quicker.
