Aja IO HD Cross convert
on Feb 10, 2009 at 4:18:43 pm

Hello, Can I use the IO HD to cross convert an HD tape 1080i 29.97 to capture on Avid at 1080sf 23.98? It works as stand alone converter from interlaced to interlaced but I cant get it to work from interlaced to psf. Any Ideas.
Thanks!
Ruben

The ioHD is a wonderful tool and it houses a great number of capabilities.

Unfortunately, it does not do that type of conversion, that being frame rate conversion/retime from interlaced 60i to psf 23.98.

Sorry about that.

If you have certain camera/tape formats that contain rp188 info, the IoHD will remove pulldown from various sources (the Panasonic variety of 720p cameras being one of them).

What's your source material?

Thanks Jeremy! I read about it and found that it doesn't do it. We will rent a AJA FS1 for the conversions. All the material is HDCAM 1080psf 23.98 and the project was edited on FCP at the same rate using prores hq. The idea was to make a master in HDCAM in 1080i 29.97 to send out to our clients and at the same time use the IOHD to copy the original tapes from one format to the other. Any other suggestion will be greatly appreciated.

Thanks
Ruben

Ah, well the ioHD will add pulldown to 23.98 material to get it up to 29.97.

Why not keep client material @ 23.98?

The footage will stay in 23.98 to archive. I think the client wants a dub of everything in 29.97 to use in their system and to keep as their master. You know how clients requests are! Thanks for your help!

It's not a problem to make 29.997 masters from 23.98 material, but capturing 23.98 from 29.97 material is hard with the ioHD. If your clients are ok with that, then everything is ok!

Let me bother you one more time! If I have a 1080psf 23.98 project on the FCP, how do I set up the IOHD to send 1080 29.97? I cant select it on the menu.

CHnage FCPs video output to 1080i29.97 10bit or choose a 29.97 easy setup.

Change FCPs video output to 1080i29.97 10bit or choose a 29.97 easy setup. if you choose the easy setup route, just know that any subsequent sequence you create will be 29.97.

Hello Jeremy, I have a question about footage conversion. I edited a project in FCP in 1080i 59.94 all the footage is on the same format. How can I print my timeline to tape at 23.98 using a kona 3? Can this be done? I changed the video output to 23.98 and it plays on the FCP but it it doesnt play on the hd monitor. I changed my tri-level reference to 23.98 and didnt work either. Any suggestions? Thanks!

Sorry but that is not a function of any Aja product,

there is not a miraculous tool here, if you want to work and deliver 24p material you need to shoot 24p material in-camera to start with or use the software tools from Nattress or have this done in hardware at a company like Filmlook.com --- they specialize in that conversion.

You can't as your timeline is 59.94 and output is 23.98. The Kona does not do frame rate and image converison of this sort. You will need to get that conformed with external hardware or try your luck with a software conversion.
