➤ (XDCAM writeback) If you export a 720p50 or 720p59 sequence with an odd number of
frames, you will receive a message indicating the sequence needs an even number of frames
to export successfully. Add or subtract a frame and perform the export again.
➤ You might experience dropped frames when playing back XDCAM media with effects.
When playing back media, a number of variables affect play performance; such as your CPU
power, GPU power, sequence complexity and the raster settings. Depending on the
complexity of your sequence, you might need to render some effects if you want to preview
them in real time and at full quality, or before you can output a finished sequence.
➤ When you batch import XDCAM clips from a virtual volume, the system re-imports the
proxy media into your bin. If you batch import XDCAM clips directly from the XDCAM
disk, this works as intended. If you do not have access to the XDCAM disk, Avid
recommends that you import the hi-res XDCAM media when you import from a virtual
volume and then edit your sequence.
➤ When you import XDCAM files, be aware that Avid does not support the batch import
workflow when you are working in the following Sony XDCAM camera modes: Picture
Cache Record Mode, Interval Record Mode, or VFR (Variable Frame Rate) Mode
(UCC/OCC - Undercrank/Overcrank). An error message appears which informs you that the
video is not supported. However, the High-Rez versions of these clips can be imported.
Their timecode values, however, will be inaccurate. The Avid editor appends its own generic
timecode to clips recorded in any of the previously mentioned modes.
➤ XDCAM proxy media will not export to a QuickTime reference movie. This is a limitation
for all Long-GOP media types.
If you export as a regular QuickTime movie, MPEG 4, or as Windows Media 9, the export is
successful. Or, you can transcode the proxy sequence to DV 25 or MPEG-IMX and then
export as QuickTime reference.
Workaround: Import the whole XDCAM HD clip and then transcode it.
➤ The Avid editing applications refer to XDCAM HD 25 Mbits media files as HDV 1080i
50/60. These Dynamic Relink settings are only available in project types 1080i/59.94 HDV
or 1080i/50 HDV.
