anamorphic to Beta Sp

[Jeff Carpenter]

A digital camera crop or an anamorphic lens shot should end up being the exact same thing as far as the tape is concerned. With the digital crop you’ll be losing resolution, so the quality will be less, but either way the tape is a widescreen image squeezed down to 720×480.

So however you would dub a normal DV tape to Betacam you could dub an anamorphic image to Betacam. The trick is what you do with that tape later, but as long as you have a method of expanding it later then yeah, the dubbing itself shouldn’t be an issue.

Thanks for the quick reply.

What Jeff says, and the alternative is to send out a letterboxed Beta SP for subsequent enlargement. If you are giving this to projectionists, they should be able to take whatever you give them and size accordingly. To gain the most resolution yuou should output anamorphic 720×480 (or 720×486 if you are working in uncompressed) and have the projection guys stretch the image to the correct 16:9 aspect ratio using a switcher. if you give them a letterboxed copy, your image will essentially be 720×404, and this is where you lose the resolution Jeff is taking about. The switcher will then scale the image up to fit the 16:9 screen. Hope this helps and makes sense. If not please post back.

If you are not giving laying off for projection, then the monitor will have to have a 16:9 squeeze option (such as most newer broadcast monitors) to view the image in the 16:9 aspect ratio.
