Yes. Nano tags the file as 50Mb XDCAM HD to fool NLEs. It has been problematic for many of our clients so it is usually not my first recommendation for file based workflows.

> Interesting conversation about XDCam , nothing new except for the mention of the dreaded NANO flash. Yes it uses an MXF wrapper, all be if different than AVIDs. So firstly you can't AMA volume to it as the folder structure isn't recognised. To AMA the individual MXF files from NANO flash and then transcode leads to problems relinking in an offline/online workflow. I hear of people using calibrated Q to wrap the mxf as QuickTime references and using these for the AMA workflow in mc 5. Others just import and then transcode. 2 long steps .

It's critical that you keep the ENTIRE folder from the SxS card - don't just copy the media- copy the entire folder to your drive before trying to AMA. Avid needs to see the folder structure- otherwise, it won't work and you'll jump through 20 hoops just to get the media into your system. If you copy the entire folder, it's a cake walk- don't link to the individual files, link to the entire folder. Also, make sure you've got the correct Sony AMA plug-in. It's not provided by Avid in the regular media composer installer: it's a separate file. I think you can get it form the XDCamEX mini-site, but probably also from Avid.

We shot tests at various bit rates at 1080 p 23.98, recorded to Nano, and I brought the files via AMA into a Mac Avid MC 5.5 at 145, 180, 220 and 280 MBps. The 220 and 280 rates had black frames like you did. Maybe Avid can't handle the datarates?

The EX3 shoots mp4 natively (which is fine for FCP and Transfer Tool) and I couldn't get Avid AMA to link to it. The EX3 can wrap clips to mxf, but evidently you have to set the camera to shoot that way. I did some research and the solution is to use the XDCAM clip browser to rewrap to mxf. It's Export>MXF for NLE, and choose a destination folder. Avid AMA can then link to it.
