The Datavideo HDR-50 is a HD-SDI / SD-SDI recorder and player with a removable hard drive enclosure. The HDR-50 records from standard and high definition video equipment via SDI, with a convenient loop through / pass through for monitoring. RS 422 and 232 remote control interfaces are standard. The HDR-50 provides a choice of recording formats in MPEG-II including 1080i, 576i and 480i with a choice of IBP or Intra-frame (i-frame). The recorded files are compatible with a wide range of NLE and play out solutions.

The compact 1U - 19inch, rack-mountable design can be easily integrated with other equipment on OB trucks, installations, or Datavideo�_ Mobile Video Studio range.

The recorded .M2T files are compatible with a wide range of NLE and play out solutions on the market, and once the recording have completed, the hard drive carrier simply ejects and connects to a PC or MAC based NLE system via USB-2 (no extra power supply required, as USB-2 provides power, perfect for lap-top use in the field).

The maximum hard drive capacity is currently a 320GB, 2.5" SATA Hard Drive. A 320GB hard drive is included with the HDR-50.

The Datavideo DN-300, 400, 500 recorders, the HDR-40, 50, 100 and 200 recorders and the HRS-10 and HRS-10HD recorders are all FAT32 based with an approximate 2GB file limit and can all record M2T files. There can't be clips longer than 2GB, resulting in multiple files per track. Also, the Open GOP structure of the 1080 stream requires information that is contained in these multiple files to have a contiguous video / audio file. Because of the nature of Open GOP compression, some NLE systems (such as Final Cut Pro) may not combine the M2T files when imported, so this needs to be done prior to import. Datavideo provides a utility called M2T_FileCombine Mac version (285KB) or Windows version (11KB) to combine the M2T files for you. Once your videos are converted, you can then import and view the files on Final Cut Pro.

Datavideo recommend using a 2.5��SATA hard drive with 7200rpmand a8MB buffer. 

Seagate Hard drives are not recommended for use with the DN-400, DN-500, HDR-100 and HDR-200 recorders.

The following are HDD that the manufacturer has successfully tested and are therefore recommended.

The recorder comes with a 320GB drive.
