FCP Resize Algorithm

[Rafael Amador]

Hi Eugene,
FC have three quality levels when rendering Motion Effects.
You can choose in the sequence setting Linear/Normal/Best.
No idea of the filters that FC use for up/downscaling.
If you use the “Rotation” function, all those Motion Effects will be rendered Linear.

Eugene I can tell what it isn’t….it is not Bi-Cubic like
it is in Sony Vegas.

I wish apple would address that, its a real pain not having
good high quality resizing….kinda comes in handy huh?

[Eugene Lehnert]

Yeah. I use our UKON to upconvert and downconvert the video material that I get but sometimes I use the motion tab to blow stuff up by a small percentage when it’s progressive material. I wanted to see if I could get a plug-in that used similar algorithms as the Snell & Willcox Ukon.

While Video Purifier by Innobits is most known for its video noise reduction it also has an excellent scaler. https://www.innobits.com/purifier.html

Depends on sequence settings. I tested these once using anappropriate test pattern. Fast setting uses (bi)linear interpolation (same as used in canvas). Normal and Best settings appear to add fairly sharp anti-alias filtering, couldn’t tell how the interpolation method changed.

Best is slightly better than Normal, Normal is way better than Fast.

The FC manual have been really improving with the years but still miss some very important info.
Nothing about those filters.
