I am currently prepping a short film to be shot on Super 16. I know it will finish on DV and likely seen mostly on people's own tv sets or laptop dvd players.

Now, I am a huge fan of the 2.35 aspect ratio and would love to frame for it on this short. However, a colleague of mine mentioned that it could cause a resolution loss. His reasoning: A 2.35 close up is basically a cropped 1.66 medium shot, meaning the face is actually smaller in the frame. And since the smaller objects get in the frame the less sharp they become, a 2.35 close up will not be as crisp as a 1.66 or 1.85 close up - on tv, not projected film.

How drastic will the difference be? And is it any better when the DV is projected (eg at a festival)?

Thank you very much for your advice.

For a 2.35 letterboxed transfer, there's no resolution loss because all it means is more scan lines are devoted to black bars -- but the picture itself has the same resolution, it's just smaller on the same screen as something not letterboxed as much. It didn't get "softer" by being letterboxed, just smaller vertically.

However, if you ever ENLARGE this image for any reason, or transfer it to film, THEN you'll see a resolution loss because of the fact that the actual 2.35 image is made up of fewer lines of video.

Right. Technically it's the same. But I think he meant that to eye, the image isn't as crisp because it's smaller on the screen. Does this seem significant enough to worry about?

Thanks again.

Why would you shoot a 2.35:1 aspect ratio if it's destined for TV?

If you're worried about resolution and your program will be shown off DVD and not, in fact, DV.... you can gain a little for your resolution by creating it anamorphic for the dvdplayers to decipher. Talk to your DVD authoring person about this if that's your final destination. DVD players will play it wide on wide screens and letterboxed on normal screen. I'm always surprised that more people don't take advantage of this.

Ever heard of aesthetic reasons? :rolleyes:
