realtime deinterlacer?

[jriker1]

I am trying to cleanup some jittery footage with DePanStabilize. Does a great job. Only problem is it requires progressive content. I'm OK with that, just makes it near impossible to preview what's going on due to the processing required to deinterlace. I'm using QTGMC for testing with fast preset. Does anyone know of a deinterlacer for AVISynth that will run in realtime. I don't care if the quality is crappy, I just need something I can preview without having to render with each setting I change in my script.

Thanks.

Thanks Feisty2. Wish I could rely on AVISynth MT not to crash all the time. Using the standard one you are stuck to limited ability to utilize your CPU's without. I use multiple avs files at a time to utilize more of my CPU during encoding but previewing things tend to be slow.

Just tried bob, and it's "better", but still not realtime for me. Note my faster computers are running as servers (where I do the final encoding with whatever script I come up with) that I remote to without monitors so am using a Dell desktop I normally use for VHS encoding to digital to test out the scripts right now. It's a Dual Core 3GHz E8400 CPU machine, so no super slouch but not sure if my faster machines would make any difference in a preview situation without using the MT version.

A less fancy deinterlacer is LeakKernelDeint YUY2/YV12/RGB, dont know if faster than bob.

There's no reason to assume anything could be significantly faster than Bob, since all Bob does is a cubic interpolation.

For that matter, Bob ran about 30% faster than LeakKernelBob on my 1440×1080i sample (after subtracting source decoding time), though both were in excess of 500 fps even on my four-year-old laptop.

It's far more likely that the bottleneck is either source decoding (solution: dump it to a lossless intermediate) or Depan (solution: use a faster computer).
