Not that I can see, but that’s mainly because I have not had any issue with this before.
Before moving to P2, we shot Betacam SP and captured using a DSR-45P DV/DVCAM deck. Thus the codec was Apple DV, and it looked really really good. And sure, it was uncompressed analogue source.
Surely the DV codec does compress quite much. Then going to DVCPRO50 (equal to Digibeta) on SD we believe the upcoming project would at least not look worse…
