Video Setup: Data-Rate, Codec, Psf I/O - Convergent Design nanoFlash User Manual

This turns off the LCD backlight after 15 seconds of inactivity. The LCD backlight
consumes about 0.2 watts of power, so this provides slight power saving.
Create Settings.txt: Primarily a tech support diagnostic tool, creates a file settings.txt with all
current settings. Only use this option with a formatted, blank CF card inserted. (ver1.5.31)
Create Menu.stg: Saves menu settings to an inserted CF card as "Menuxx.stg" (1 to 20) into
a created }CFG{ folder. Menu settings can be saved and restored. See discussion in
"Managing Your Menu Settings" Addendum.
Restore Defaults: Restores factory default settings.
About: Displays the current firmware version number.
Video
Bit Rate
This option allows the user to set the compressed bit-rate of the video being recorded. Note
that most NLE's place a 50 Mbit label on high bit rate files, but nevertheless accept the high bit
rate files natively. The actual bit rate of a file can be seen in Quicktime Player by using
Window->Movie Inspector, which has a bit rate field. For MXF, the bit rate can be seen in the
XDCAM Viewer (an MXF Player, see link in Software Accessories), Product / Version fields
(under View->Metadata). (ver1.5.31)
HD Bit Rate (Quicktime, MXF)
1. *18/35 Mbps = Full-Raster (1920x1080/1280x720) 4:2:0 Long-GOP (XDCAM EX)
2. *18/35 Mbps = (1440x1080/1280x720) 4:2:0 Long-GOP (XDCAM HD)
3. 50/(80 ver1.5.31)/100/140/180 Mbps = Full-Raster (1920x1080/1280x720) 4:2:2
4. 100/140/180/220/280 Mbps = Full-Raster (1920x1080/1280x720) 4:2:2 I-Frame
SD Bit Rate (Quicktime, MXF)
1. for Standard Def: 50, (40, 30 ver1.5.31)Mbit IMX 4:2:2 (720x486/720x576)
* 18/35 Mbit recording depends on 35 Mbit 1080 Width setting (below) (ver1.5.31) .
HD Bit Rate (MPG)
1. 19/25/35 Mbps (1920x1080/1280x720) 4:2:0 Long-GOP
SD Bit Rate (MPG)
1. 5/9 Mbps 4:2:0 Long-GOP
CODEC (Long GOP / I-Frame)
This option selects the XDCAM 422 CODEC format. Long GOP supports the bit rates at 18,
35, 50, 100, 140, and 180 Mbps. I-Frame only allows recording at 100, 140, 180, 220, and
280 Mbps. The nanoFlash utilizes the high quality Sony XDCAM 4:2:2 CODEC for video
compression. The data rates of 100 Mbit or greater Long GOP and 180 Mbit or greater I-
Frame are generally considered to be Master Quality video. In brief, long-GOP codec
compresses 12 or 15 frames at a time, sharing the information between the frames, resulting in
greater efficiency (in part by throwing out duplicate information), especially at bit rates of 100
Mbit and below. I-Frame codec compresses each frame separately. The highest quality video
recording from nanoFlash is 280 Mbit I-Frame.
Record PSF->Progressive
Turn this option "On" to record PSF input video or progressive input video as progressive.
Turn "Off" to record PSF input video or interlaced video as interlaced.
Play Progressive->PSF
