1440×1080 DVCPRO 50i to 1920×1080 10bit uncompressed 29.97?
Hi Folks
This client has thrown another problem my way. He has a DVCPRO 1440×1080 50i FCP Sequence that needs to be be converted to 1920×1080 10bit Uncompressed 29.97 to be encoded for Blu Ray. I was thinking of doing some test through
his Kona Card but wanted to ask the others thier opinions on correct workflow first.At first I was thinking the conversion would need to go through a good (and expensive) hardware converter but was told by a post house in Burbank that the sequence would be converted through their Kona Card.
Being the skeptic I am, what would be the prefered way to do this conversion?

Is this going to HDCAM? I ask because it seems silly to cross-convert just to go to BluRay. The video will not look any better.
The Kona card can do lots of really nice conversions BUT going from PAL to NTSC is not one of them. You can’t take a 25i or 50p signal and convert it to 29.97 without going thru a standards converter. This would be something that a high end post house would have.
I would not suggest that you do this thru software conversion, unless you test it out and your client accepts it. But I would imagine that Compressor could do this but you may have some field flickering issues. Export a small portion of your program and try it. See what happens.

No…it going tobe a file to file conversion and encoded that way. It has to be converted since N. American BD players do not support 50i playback. I’m skeptical too of software conversions and two post houses in Burbank have already said going through a Kona card would be the way to go.
I will do a 5 min test through Kona and Compressor to see what we come up with.

I’ve been using AJA products for years now, and standards conversion is one thing the Kona series can’t do. You can do anything within that standard, but not between standards.

Yeah…you’re right. I’m going to try doing a small 5 min test through Compressor first. If we’re not happy, it will have to be through an Alchemist tape to tape, then captured uncompressed to a digital file. Oh….The Horror!!
