SYNChronizedRECord

<clipname> <starttime>

The SYNChronizedRECord command is used to 
schedule recording of a clip at a specified time. A 
clipname must be provided, and the start time must 
be specified using the time format 
yyyymmddhhmmss (24 hour time).

Start recording a clip named Rec227 at 

3:05pm, June 9th 2005.

The 

 command is typically 

used to synchronize multiple DGy recorders so that 
they will perform as a multi-channel recorder. 
Before using the DGy in this mode it is 
recommended that the real-time clocks of each 
recorder be synchronized using either an IRIG or 
NTS time reference (synchronizing is then 
automatic). The 

 command 

should then be issued to each machine using the 
same time argument.

RECordFrameRate

<0 .. 100>

Sets the rate at which input frames are recorded. 
This command would most likely be used to save 
disk space by recording at a lower frame rate. For 
example, a 1280 x 1024 image can typically be 
recorded at 30 frames/second. A setting of 15 would 
record at half the rate, with double the available 
recording storage time.

An argument of 0 always allows recording at the 
maximum rate which is calculated automatically by 
the DGy.

: RECordFrameRate must be set to 0 for 

multicast streaming with interframe compression 
enabled.

Default: 0

RECordBitRate

<0.1 .. 8.0>

Sets the degree of compression i.e. quality level 
(Stated in bits/pixel). 

 effectively controls the trade-off 

of bit-rate versus quality. Without regard to 
recording frame rate, an argument of 0.1 reflects a 
240:1 compression, with an argument of 8 reflecting 
a 3:1 compression. (Compression is measured 
relative to a 24-bit pixel)

Quality levels are related to compression level, for 
example:

RECordBitRate 0.7 is low quality (34:1)

RECordBitRate 1.0 is medium quality (24:1)

RECordBitRate 1.5 is high quality (16:1)

Default: 1.0 (medium quality)
