Outputting DV to Digibeta
Hello if anyone has any input on this, that’d be great.
I have a project on FCP HD whose material is all Mini-DV. However, the project will need to be output to digibeta for completion.
I will be doing this via the AJA io but here is my question(s):
Will all the DV media need to copied from the firewire drive to Raid drives in order for it to be output to digibeta? Or is the AJA able to output through SDI even if it’s coming in DV? Additionally, if the media needs to be copied to the Raid drives, the sequence will also need to be re-rendered at 10-bit quality from DV quality, right?
My guess is the sequence can be put onto digibeta from the original DV source, but it will be DV quality rather than 10-bit quality. But I very well could be wrong about this.
Thanks very much for your help!

No, You are still playing DV video, the Io simply transcodes it to SDI.

You are right about this. You can’t make a silk purse out of a sow’s ear 🙂 Your DV video will still be DV quality. The good new is it won’t be any worse than the original captured DV quality (which I think is quite good for acquisition).

Ok, as I suspected. Thanks for your reply!

Actually if you are to do any color corrections or comps, they will come out much better if you load in at 8 or 10 bit uncompressed. If this is not the case, dont waste your time and keep it at DV compression.

I did this for a doco. Unfortunately it went thru a Decklink card not IO but same process. I wanted the effects and titles to come out as 10bit for broadcast & to Digibeta. I plugged in the firewire drive and then copied the files across to SCSI. I did do a media manage (before going to Post) so that all that I was sending across was the timeline and not all the footage in the bins (save heaps of time and $). Yes I did not want to redigitise all the footage either thru their SDI and thus pay 3hrs digi time.
Now that the project was on the uncompressed system it was opened and all the footage in the final DV timeline was put into a 10bit timeline. There is a big issue with DV and uncompressed (with PAL) because the fields are opposite. Lower for DV and Upper for Uncompressed/SDI/Component. I think they are both lower for NTSC (please check this). Thus I needed to use a Nattress plugin for Fields to make the DV upper.
Then we rendered it all and mastered out to Digibeta.
Expect 2-3hrs, in case you make changes whilst there. Went to ABCTV and passed their stringent technical checks.
