Jeff,
we tested both: MC and Carbon. None of these was as good as Telestream. But Telestream only is useful for frameblending. we have negative experiences whith motioncompensation or other advanced methods when aplying it to “heavy” material. There are too much errors. not useful for a standardtool for standard conversion.
What I mean there is a lack between the 1K and the 50K (and corresponding the quality!) that’s beeing filled… for what I found.
AviSynth could do it as you can remodel almost every algorithm within it. But that’s hard to find out.
Tobias.
