Does the Cinealta record to 29.97 with 3:2 pulldown?

Matt,

The Cine Alta has eight speeds:

23.97 PsF
24 PsF
25 PsF
29.97 PsF
30 PsF
50i
59.94i
60i

When it records at 23.97 and 24 it slows the tape down and records distinct, unrepeated frames at those rates, no built in pulldown.

When you record at 29.97, again every frame is a unique progressive type frame (both fields are the same). To get a "telecine-like" effect you must play the tape out through a capable Sony VTR such as the HDW500 or J3H.

This was the origional specification that George Lucas and others in Hollywood sought from Sony in the development of the camera and it was only later when Panasonic developed their Varicam that the builtin pulldown concept was realized. Since then I think most people understand that it's a great feature toi have, especially because so much monitoring, editing, distribution and exhibition is done in the NTSC environment.

[john sharaf] "To get a "telecine-like" effect you must play the tape out through a capable Sony VTR such as the HDW500 or J3H."

On the Sony website it says the JH-3 has an internal 3:2 pulldown engine. Does this mean if you shoot at say 24p you can capture at 29.97? If so, are there any issues with syncing audio?

Yes (you can capture at 29.97 in standard def downconvert) and no there are no issues syncing sound!
