DVX100A 12 bit - Firestore 8bit ?
 
The fs-4 specs read:

Audio/Video/Timecode Specification
25Mb/s, 8-bit 4:1:1 (NTSC-DV) or 4:2:0 (PAL-DV) video (model dependent)
DV Embedded Timecode (Drop or Non-Drop)
Embedded 2-ch (16-bit, 48kHz) or 4-ch (12-bit, 32kHz) Audio

Doesn't the dvx100a record using 12bit processing?

Are these specs referring to different things?

Different things. The internal DSP of the DVX is 12-bit, but the recorded DV format is all 8-bit. Every DV camera (from a $299 Circuit City handycam up to a $18,000 Sony DSR450) all record on tape in 8-bit. And that's what the FireStore records.

What method to downgrade 12-bit DSP video data rate to DV 8bit?

TIA

What Barry is saying is that it is already done withing the DVX. It is not something you should worry about.
