Dear All,

I see. That makes sense! So that leads me to wonder: Is it easier/better to chroma key off betacam or digibeta or off DVCProHD to tape?

Any thoughts/experiences?

Best,

Dear Noah,

Thanks. I get it. But that makes me ask: so, if that’s the case, what is the point of having HDSDI out on a DVCProHD deck? And what’s the point of going in HDSDI at all then, why not just FW if it doesn’t matter since it’s been compressed on the tape anyhow?

Best,

Thanks for all the data, und vielen dank (for the Germans)!

Unfortunately it is not feasible to go tapeless and uncompressed most of the stuff because a lot of it will be greenscreen interviews in the field where it isn’t practical to bring your computer or even a bunch of drives.

Have you been able to chroma key succesfully from DVCProHD off tape before?

Isn’t it much better when you go in HDSDI as opposed to FW?

Thanks,

Hi,

Thanks a lot everybody for your tips.

In answer to a question, no we haven’t tried those. We have ultimatte and a Nitris. But that should work, right?

The thing that doesn’t make sense is that chroma keying on Betacam and Digibeta shouldn’t be better than doing a chroma key with DVCProHD right? (Or only if it goes in through HDSDI and “uncompresses” as opposed to firewire which stays compressed.

The other issue is what if this is due to the Avid DNXHD compression codec. I don’t get totally how this works, but if you went into a Nitris via FW and it compresses stuff with the Avid codec, then wouldn’t you be getting DVCProHD compression and then Avid DNXHD compression on top of that? Because Avid doesn’t work natively with that HD Codec like FCP does. So I’m wondering if the tests were horrible because everything was compressed once or twice and with HDCAM you can’t firewire (if I’m correct) so they had to bring it in uncompressed for tests.

Am I correct? Is there any reason they would get better results from Betacam than from DVCProHD? (doesn’t make since because the resolution is so much better and everything so much sharper).

THANKS!

Dear Oliver and Michael,

Thank you both very much for your data. This is for use in our own facility on our own projects so we don’t have to worry about clients, just about whether or not it works well for us.

We are doing DI’s, but that’s not all we’re doing. We also shoot video (Digibeta switching to some form of HD soon) but mainly the smoke would be used for finishing projects shot on film and then either telecine to HDSR or 2k scans (most likely most projects would be put on HDSR with an HDSR master, offlined on Adrenalines or FCP and then finished on Smoke). That’s the idea but we don’t have a Smoke yet or FCP to be able to test it out.

Does anyone have any experience with either FCP or Adrenaline going to Smoke or some other comparable finishing system and which line is easiest/fastest/best? That’s what I’m trying to figure out. That effects whether or not we cut in FCP 5 (HD) or Adrenaline DnxHD for our film projects.

DsNitris is an option too, but Smoke seems to have a lot of cool things that DsNitris doesn’t have and DsNitris per the Avid guys themselves is not yet capable of really handling 4:4:4 RGB, but Smoke is, right?

I’ll try asking a simialar question in the Smoke forum but it would be great to have your experiences outside of Smoke as well.

Thanks!
