5DMK2 convert question
Hi DVINFO members,
I am a new member Dvinfo and Neo(HD) Family. I have a question. 1-Canon 5dmk2 files put to After Effects. (direct, cancel the HDLINK convert) 2-AE color bit depth: 16 bpc(edit,fx...etc) 3-Render ( Cineform Avi, RGB+Alpha ,Trillions of color +,Film scan 2, Enable 4:4:4 encoding ) 4-result : 4:2:0(8 bit Canon file) to 4:4:4 (12bit CF avi) Is that correct ? or 1-Firstly HDLINK convert(4:2:0 to 4:2:2) 2-AE color bit depth: 16 bpc(edit,fx...etc) 3-Render ( Cineform Avi, RGB+Alpha ,Trillions of color +,Film scan 2, Enable 4:4:4 encoding ) 4-result : 4:2:0(8 bit Canon file) to 4:4:4 (12bit CF avi) Is that? I'm confused..! Thank you. |

Re: 5DMK2 convert question
Neither works like you imagine. You can't get 4:4:4 from a 4:2:0 source, although you can guess at the missing data to smooth out chroma artifacts. The HDLink 4:2:0 to 4:2:2 is doing this type of chroma artifact reduction. When decoded it will optionally do 4:2:2 to 4:4:4 chroma smoothing (if you select "Filter 422 to 444" in the "C" systray control). So HDLink does all you need, there is no gain in baking it all into a new 4:4:4 file which is twice as big without twice the information. If you go with you first approach, using CS directly, where is your 4:2:0 to 4:4:4 interpolation occurring? Short of add filters, AE or PPro makes no attempt to fixing chroma 4:2:0 artifacts, so you would end up baking the artifacts into a large 4:4:4 file -- zero gain, backwards step.

Re: 5DMK2 convert question
1. Drag and drop your 5D files into HDLink for conversion
2. Done. |
