XDCAM HD playback on the timeline
by Rick Dolishny on Apr 2, 2008 at 10:44:33 pm

OK what's the deal. No matter how I try, XDCAM HD footage plays back stuttering. No real time at all.

I tried Transcoding a short test timeline to DNxHD and it looks great.

Am I simply not able to play back XDCAM HD footage in real time?

Rick,

Which Avid software?
Which XDCAM data rate? 35Mbps?
What's your hardware profile?

Ah yes, of course. Kinda new to this forum.

Symphony Nitris, 1.8. XDCAM not sure but it's lighting up 1080i on the playback deck. I'm trying to capture at either of the DNxHD selections they are all slow.

I have no issues with HDCAM footage that I digitize via HDSDI. I have also just discovered I can transcode a test timeline and it plays fine.

The Nitris ReadMe says on multiple occasions to transcode to DNxHD to get around XDCAM issues. It even suggests the same for DVCPRO HD:

"Avid Symphony Nitris cannot always play back native DVCPRO HD media without dropping frames. This is due to the fact that on playback, the system has to create a version
of the media at 1920x1080 at full resolution on-the-fly.
Workaround: Transcode the media to Avid DNxHD or uncompresssed HD for real-time playback."

So I guess transcoding is the way to go.
