XDCAM and slow mo clips
Hi,
Did some testings today with Sony XDCAM and FCP 5.1.2 and works very well except that those clips shot in slow motion (50fps) shows up in FCP as Apple XDCAM HD MPEG-2 in the compressor column whereas the rest (normal speed, fast speed in 50i and 25p) shows up as Sony XDCAM HD 35Mbit.
First I can’t find this Apple XDCAM HD MPEG-2 codec and when I put it in the XDCAM HD 35Mbit sequence, it requires a render which plays back fine after render.
Just wondering why these slow motion clips shows up with the Apple XDCAM HD MPEG-2 compressor description.

Hi Crispy,
XDCAM HD achieves slow-motion by reducing the number of lines recorded from 1080 to 540. If you look in the clip info area for these clips in XDCAM Transfer, you’ll notice that the display size says 1440 x 540, instead of the 1440 x 1080 for your normal speed (and fast motion) XDCAM HD clips.
FCP can’t handle the 540-line clips directly for RT editing which is why they show up as a different codec, and they need rendering as you found. I guess that usually only a small proportion of a sequence will be slow-mo so that this isn’t often a big price to pay.

Hi,
Yes I did notice the 1440 x 540 display size on the slow motion clips. They did actually look less sharper than the normal clips.
Thanks,
