MPEG-2 from FCP7 not recognized

Hi,
I'm trying to import a FCP7 XML with MPEG-2 files generated by FCP7 from XDcamEX footage. Resolve does not see the files on the hard drive, as if they weren't there.

Resolve is version 11.1.1 lite on Yosemite.

The files are visible in the Finder and can be opened in Quicktime.

Temp solution is to do a Media Manager and convert everything to ProRes, but if anyone has a solution to be able to work with the native files...

Cheers,
Damien

PS I have tried downloading the Sony XDcam plugin for Mac, no change.
PPS Downloading Resolve 11.3.1 to see if it changes anything.

We know what you want to do, but you have not explained why you have chosen to grade MPEG 2, which is certainly not a good choice for many reasons, including bad compression low color depth.

Hi David,
I want to grade Mpeg-2 footage because that is the native shooting format.

I have solved my issue by installing the Apple Pro Codecs thanks the the great utility unPKG.

Cheers,
Damien

In order for Resolve to see your XDCAM footage it has to be in a Quicktime wrapper (.mov) and have the appropriate Sony codecs installed on the system, which must be a Mac. Resolve won't see MXF wrapped XDCAM. If the Resolve system is a PC then you're out of luck as it can't work with XDCAM EX footage.

Best option is edit with your native footage, and when going to color do a conform on the timeline to export out ProRes or DNxHD options for the colorist. Those codecs are much better suited to editing, color, and vfx.

XDCAM is a MPEG-2 based codec with a 4:2:2 color sample and an 8-bit color depth. While not ideal to edit or finish in it "technically" is broadcast worthy (at least according to Sony!).

Gotcha Ryan! I thought he was referring to a straight-up MPEG 2 file, as in DVD quality in 4:2:0 color space, not a camera original MPEG variant.

Thanks all for contributing to this thread.

Of course MPEG-2 is not ideal for grading, but isn't it best to grade your native footage and avoid going through a transcode, which may not be optimal?

If you grade your native files, you avoid a generation loss. Of course my renders and exports out of Resolve are either in ProRes 422 HQ (when going to Broadcast, web, DVD and BDR delivery) or ProRes 4444 when going to DCP.

Cheers,
Damien

It's kind of a toss-up... Transcoding to Pro Res before grading could, in theory, I introduce some artifacts, but grading a hi-performance codec like Pro Res has numerous advantages as well, including faster and less processor intensive renders.
