For those of you who are interested... I do work as a field engineer in television news; we use Sony Betacam SX (compressed 4:2:2 digital) to shoot original news. I always thought our camera originals looked fantastic (well, as fantastic as you can get in Standard Def 720x480 video) but have now had a chance to dump over some original material and compare DVHS to Beta SX... DVHS completely blows a $50,000 SX recorder away with NO visible artifacts, compared to slight (very slight) ones in SX....


If this were a rugged transport, it would be hard to not consider it seriously for professional use.

Yes, the JVC 30K does a great job encoding 720x480.

In STD mode, the video bitrate is around 11 Mbps, which

is more than enough for "transparent" encoding.


If you are willing to expend twice as much tape, you

can also encode 720x480 in HS mode. Although the Transport

Stream rate is around 25 Mbps in HS mode, the limit

for MPEG-2 [email protected] video is 15 Mbps, and that's the rate

that is used on the 30K (with lots of stuffing packets

in the Transport Stream).

And, the compressed MPEG2 stream can be passed over firewire to other devices for upscaling, FFDSHOW processing, format conversion, burning to DVDR, etc. I'm surprised more people aren't taking advantage of this capability.
