Jeff Herman Posted August 1, 2011 Share Posted August 1, 2011 (edited) I'm trying to understand how to convert to the 2.39:1 format from the standard 16x9 format that my camera shoots in. I see three possibilities on how to use this ratio in my projects: a) Originally shoot scene as 16x9 and stretch video image to 2.39:1 in post (i.e., no actual cropping to the image). b) Originally shoot with an anamorphic lens (i.e., no cropping and no additional work in post). c) Originally shoot as 16x9, but in post crop to the 2.39:1 ratio (i.e., loss of content on the top and bottom of the frames). Assuming I have no anamorphic lens (which rules out b), what is the most accepted means to get the 2.39:1 widescreen format in post (a or c)? In the case of c, then I would need to be careful in shooting the scenes that the video image of the actor heads are not cut off when cropping the top and bottom portions of the video frame. My preference is (a), but that might overly distort actor faces (etc.). I would appreciate an answer to this question if anyone knows. Thanks.

dan kessler Posted August 1, 2011 Share Posted August 1, 2011 Choice (a) will definitely distort the image. Link to comment Share on other sites More sharing options...
Jon Schweigart Posted August 1, 2011 Share Posted August 1, 2011 When shooting mask out a 2:35:1 guide on your viewfinder so you have breathing room in the frame. If you don't do this everything will look tighter and crammed when you crop to 2:35:1. In my NLE I usually put on the 2:35:1 Matte so I can adjust for headroom. In the export you need to know the correct aspect ratio so it crops and gets rid of the letterbox. So for example if you're doing a 1080p web video select maintain aspect ratio with crop, with a custom ratio of 1920x816. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted August 1, 2011 Premium Member Share Posted August 1, 2011 A is not an option. 2.39 isn't a video display format, so the question is what are you shooting 2.39 for -- for HD video display, meaning a 16x9 HD master with a 2.39 letterbox, or for theatrical release, which means a film-out to 35mm anamorphic (scope) or a 2K digital cinema package? If you could find the rare 1.3X Hawk anamorphic lenses made by Vantage, you could squeeze a 2.39 image onto a 16x9 HD sensor and recording, but at some point you'd have to make a conversion to 2.39 letterbox from broadcast and home video. But the film-out at least could use all 1920 x 1080 pixels to create a 2.39 version. But since that option is rarely done, most people just compose 16x9 for cropping to 2.39. Many digital cameras can generate frameline guides in the EVF for this. Link to comment Share on other sites More sharing options...

I know it's not cinema quality (read: sharp) but do you have any feelings about this as an option? Link to comment Share on other sites More sharing options...

Freya Black Posted November 7, 2011 Share Posted November 7, 2011 a) Originally shoot scene as 16x9 and stretch video image to 2.39:1 in post (i.e., no actual cropping to the image). B) Originally shoot with an anamorphic lens (i.e., no cropping and no additional work in post). c) Originally shoot as 16x9, but in post crop to the 2.39:1 ratio (i.e., loss of content on the top and bottom of the frames). Assuming you were working with video then for b you would still need to unsquish the image by stretching it to 2.39:1, the difference is that it would look normal unlike the mess you would get if you went with a. If you were making a film print OTOH then the projector would do the unsquishing for you. love Freya Link to comment Share on other sites More sharing options...

Probably the people doing the digital-to-film transfer would just uprez everything to 2K in the 2.39 aspect ratio (unsqueeze it basically), and then let the laser recorder add the 2X squeeze for the final scope image on film.
