Re: [Avid-L2] 29.97 and HD / RANT

I have NEVER heard of 29.97i. The interlace format is 50i or 59.94i.  A 29.97 frame rate camera setting is going to be 29.97P or PsF. To shoot 29.97i setup your camera for 59.94i and the resulting frame rate is 59.94 broken up into two fields which separately have the equivalent temporal rate of each being 29.97 frame per second but yield the soap opera look. 

If a producer is asking for 29.97i talk to the DP and if they don't know then good luck. Cause 29.97i is going to look like crap if it even exists.

I ask again: If the client says 29.97i is the deliverable (and international or web is not a consideration), why the heck should production shoot anything else???

 

This is not a rhetorical question.

Hi Patrick, I happened to deliver a show shot in Italy to PBS in january. Shooting was at 25p for technical reasons: electric lights working on 50 Hz power do flicker when shot at anything but true 24, 25 or 50 fps, regardless of interlaced/progressive. Delivery was at 30i, or 29.976 if that's the real naming or frame rate (I did not took care of mastering). I'm not a camera expert, but I guess that the same flicker applies to 60 Hz lights shot at 25 fps, so you may find yourself in my shoes one day, delivering a US shot show to a european broadcaster... Anyway, since delivery was 30ish fps I asked the DP to shoot at 30ish fps and this out of control flicker is why he didn't.
