The idea seems worth a try. Since it is such a simple modification, i
will certainly have a go at it next time i hook the PC to the projector.
If you are playing with AVS scripts, does it give better results than
deinterlacing with my TomsMoComp60_Top.avs script.
I routinely used TomsMoComp for my encodings of standard definition
videos (mainly for PDA viewing) in the past and was satisfied with the
results.
However, i doubt it will be able to operate in realtime on 1080i
material. Therefore i will have to store the result of the script and
play it afterwards.
In order to get a reasonably sized file, i will have to compress it.
Now, i am not convinced my Mpeg2 encoder handles 1080p. I know my h.264
tools do, but then i may have problems with realtime playback. I am not
sure the PC will handle it in software.
I tried once 1080@60p in h.264 with hardware decoding in the graphic
card and obtained a slow-motion video (about 75 % of realtime). I don't
know if it is because i've reached the limits of the card, or because
of a bug somewhere (bad encoding profile/level...). Perhaps a test at
50p would be useful, here.
So i may try TomsMoComp, but not immediately. I only compared with the
output of the internal deinterlacer in MPC-HC (or possibly ffdshow),
and i don't know which one is used (perhaps yadif).
More testing to do...
