XDCAM continues to take over low cost acquisition http://bit.ly/cRUGBz JVC, Sony and Canon have XDCAM cameras, and now a standalone recorder.
The new FS-T1001 Camera Mount XDCAM EX recorder records to SxS in the same format as XDCAM EX devices for maximum compatibility. I guess it could also work with the SD card adapters for SxS that are available.
XDCAM EX is now the most popular (of new cameras) recording format: JVC’s GY-HM100 works with the 35 Mbit version; Canon’s XF305 and XF300 cameras works with an MPEG-2 codec identical to the 50 Mbit/sec version of XDCAM and of course Sony has the EX-1 and EX-3 recording XDCAM EX format.
Affordable acquisition formats have settled into two camps: the XDCAM EX world of 35 or 50 Mbit/sec long GOP MPEG-2 or the AVCCAM/AVCHD world of “long GOP” H.264 MPEG-4. H.264 is approximately 4x more efficient than MPEG-2 for the same bitrate, but H.264 takes more processing power to decode.
