Capture Codec Settings
Recently started using DVCPRO 50 instead of Betacam SP on a MC Adrenaline. I have always captured 1:1 before. I see there is a DVCPRO 50 capture setting. Is this better than 1:1, the same, worse? If I use the DVCPRO 50 codec is Avid going to recapture my footage at 2:1 compression, therefore giving me a 4:1 compressed image, and resample at 4:2:2?

The footage gets decompressed to an uncompressed stream then captured at 2:1 so it is not an additive compression on the image. When it is recaptured from the uncompressed stream, it is also 4:2:2.

So then for the best quality I should continue using 1:1 on the capture setting? By the way, I am bringing the footage into the Avid via SDI.

The concept is the same, when the signal comes over SDI is is already decompressed to an uncompressed stream – 1:1 would preserve your sources as the highest quality in standard definition. Other than native DV resolutin capture, when selecting an Avid JFIF resolution, the signal is decompressed to uncompressed then captured –
