Hi,
I'm working on an XDCam project. Wondering what codec everyone recommends using when dealing with XDCam. It was shot at 1080p 23.98. In my video input, I assume I'll use the 1080psf 23.98? And by the way, what does that psf stand for?

Thanks,
Jack

Hi Jack,

Yes, that's the one to choose.

RE: "psf", it means "Progressive Segmented Frames".

What it tells the application is, "This is really interlaced video, but each field in every frame is identical so please treat it as if it's progressive when rendering effects and transitions."

Thanks.

Which codec would you recommend using for this? DVCPRO HD is panasonic based so I assume that wouldn't be the best choice. I'm on a laptop at the moment so can't do uncompressed. Apple Pro Res 422 HQ?

Also can Media 100 use the actual XDCam codec itself? Can't figure out how one would do that so I am guessing no?

Hi Jack,

The short answer to this question is "no".

The long answer isn't really an answer at all but a years long conversation that's been taking place in the industry about the merits of using long gop media in post-production. Many purists will tell you that it's best to use a "traditional" codec for editing and compositing. Media 100 products currently adhere to that belief as well.

There's no cut and dry answer to this questions. It depends on what you want to do with the final result and what sort of steps might happen in between.

Generally speaking, whatever codec you choose, you want to stick with it all the way through for the least surprises (see Matt's thread for an example of one the potential surpirses: http://forums.creativecow.net/thread/4/862475).

I like the ProRes codecs, but I have seen other conversations about some caveats when running in and out of After Effects for example: http://forums.creativecow.net/thread/2/922146#922194.

My best advice for questions like this remains...

Start at the end, focusing on the end result that you need and/or want. Work your way back to the material that you've got, then set up a small, representational version of your project and run it through the workflow to see if it's going to give you what you want in the end.

Wick,

Thanks for all the answers. Great to see the Media 100 voice on this forum.
Also kudos on the XML function in version 13. It is a beautiful thing.
