Look at your camera specs and compare them with Dat to know if it is worth the extra trouble to work with Dat. The new cameras have great specs in some cases.(posted 8109 days ago)Dats record at either 44.1 or 48 KHz, and at 16- or 18- or 20-bit (higher is better). Remember that 16-bit digital audio at 44.1 is far and away better than any type of analog recording used by filmmakers for decades in the past. 32 KHZ sampling is definitely a significant step down.
You do want to avoid using cheap Dats in the field - dats unable to use a video reference timing signal - for these Dats may run at slower motor speeds if the available power is weak or if they are battery driven. If you have a pro Dat w/timecode you will never have a sync problem. If you plan to edit in 29.97 ndf 48KHz, use those same settings on your Dat recorder in the field.
