HD to SD conversion “flicker free” with DaVinci?

[Blase Theodore]

[Ola Haldor Voll] “I know for a fact that Compressor doesn’t do a good job. Thin lines and fine details will flicker, and it will be kind of jumpy in “crash pans” or fast motions.”

Ola, when you used Compressor, were you turning on Frame Controls and setting scaling to “best”? It defaults to “fastest” if you don’t change it, which means Compressor sucks if you don’t tweak it.

Figured I’d at least mention it, in case you weren’t already doing that.

Also, make sure you’ve set resolve to “smoother filter” instead of “sharper filter” in the resize setting.

Thanks for the heads up. Will test tomorrow.

sounds like “smoother filter” will do the trick with those insanely flickering lines in sd on crt.

Then make sure that they are not treated as interlaced – that might introduce ugly artifacts.

I’ve done a fairly comprehensive test of conversion in DaVinci Resolve and the downconversion is amazing. A lot better then anything you can do with Final Cut Studio (including Compressor set to Best, which is really slow and not that great). Use smoother filter. Quality is good provided you go from Progressive, Interlaced scaling is not nearly as good.

good info heige!

are you referring to rendering out and not realtime downconversion right?

thanks

[Helge Løken]

Indeed when you render it out. It’s always the highest quality no matter how you’ve set up your system.

When you downconvert interlaced material you have to use the “field rendering” option in order for the motion to look correct. However, results are not nearly as great. Quite a bit of aliasing.

[Gabriele Turchi]

did you ever compared the results out of resolve to a deck (like SR or D5) downcoversion ?

in the past i compared D5 , compressor, and SCRATCH ,

D5 won but Scratch results was pretty close using the lanzcos filter (compressor with frame control on was worse …)
