for production reason we're editing a movie shot with a sony xdcam and a canon 5d with their own native codecs. The sequence setting is set as a HD 1440x1080 ProRes422 HQ, and finalcut is working rendering the two different sources (h264 and xdcam ex 1080p25).
Converting all the clips to ProRes before starting editing it would be of course much better, but it didn't happens.
The editing is almost finished, and now we've to send it to Color.
My question is: is it better to convert -now- all the clips (both h264 and XDCAM to ProRes) and re-link them on the sequence or can we just export the sequence (with the sequence settings, ProRes) in order to send it to Color? With this second choice, are we going to lose quality?
ProRes 422HQ or ProRes 4444?
