Conversion speed was 1.3 fps for dct=0, 0.3 fps for dct=1 and 1.0 fps for dct=3.

Speed for dct=1 is forbiddingly slow, there is no way I will ever use this.

And watching the results I have to agree with johnmeyer: Using a dct value of 0 produces less artifacts than using values of 1 or 3, and it is faster. I know DCT=0 will fail me on fades.

That's something odd if DCT=0 produces less artefacts (also- try fades with DCT=0).

This is definitely not a case for me, but I'm using vs (but this should not matter). I also used different/simpler script, so maybe this is the reason (again shouldn't be).

I've converted 500h worth of footage and done few days testing before this. Used DCT=3 at the end as a compromise.

I will try this script, maybe it has some magic I have to find average settings for 500h worth of footage not ones which will work for e.g. 1min clip. I know DCT=0 will fail me on fades.
