Some claim to see a difference when capturing DV thru SDI, though I have not. (unless your trying to chroma key ) I’m currently working on a 2 hour doc for broadcast shot on Digibeta, but offlined at DV resolution with many photos. Sent the client a couple check tapes, One uncompressed 8-bit SDI and the other DV50. They said both met thier broadcast standards. My current plan is to redig to DV50 and deliver on DigiBeta.
That being said, If your starting with DV material, I would keep it DV unless you have lots of GFX which always take a hit. With some short projects shot in DV, I’ll edit in DV, add text and GFX then switch the Sequence to DV50 or uncompressed and render the timeline out to kick up the GFX, provided they are of higher res. to begin with.
