5) Which de-interlace filters are used in CinGG with mpeg2enc and ffmpeg?

If you check "deinterlace" box in DVD  creation window - internal cinelerra's deinterlacer (you can configure it just before confirming batch render in second window).

I had a look in the wrench Cin video compression box.
Nothing there told me something about known deinterlace filters ......?

Sorry, I mean on timeline there will be auto-added deinterlace filter. So, you can configure it ...
