I think you might be wrong Rafalaos. I haven’t ever physically taken one apart, but from what I understand, there are actual hardware chips that are doing the conversions, within a Kona card for example. There is Not software doing stuff inside a card like the Kona. It’s actually hardware. That’s how it can do the conversions in real time as it’s happening.
At least in my own experience, trying to downconvert by putting an HD sequence into a SD seuqnece then rendering, still gives you artifcating and I can see the “uneasyness” of the filter trying to shift the fields (HD is upper, SD is lower) within the software. Yes it works. But I recommend letting the hardware do the job. In my honest oppinion, it looks 100 times better.
