Hello,
Thank you for your answer. In fact, the FCP side belongs to a customer so it’s difficult to ask him to install the Avid codecs :S
I know the Animation codec is lossless but the problem is that it works in RGB mode and the native video is in YCrCb so I’m afraid changing the color format will damage the quality.
I tried with uncompressed 10bits 422 standard (not BlackMagic), it worked with my FCP but not with the customer one.
So, I don’t know… Maybe transcoding in “uncompressed standard” with third party softwares… Any other lossless solution ?
