I’ve been prompted this week to think about 16:9. 16:9 is great but the problem is that clients (oh, them!) buy or rent these lovely big plasma screens and suddenly we have to miraculously convert 4:3 source into 16:9 and make it look good. How do we communicate that you can’t get there from here! How do we communicate to clients that 16:9 display is not a decision made somewhere between commissioning the project and turning up at the trade show? How do we make it clear that, unless the decision to shoot 16:9 for 16:9 display is made at the start of the project, then everything from there on is compromised?

There are three ways to get 4:3 source to “fit” a 16:9 display. Two of them are quality compromises and the third is a compositional compromise. Some choice! First option is to blow the 4:3 source up 133% so the 4:3 fills the full width of the 16:9 but crop at the top and bottom of the image (oh, right, that’s both a quality and a compositional compromise). Choice two is to simply keep the 4:3 at full height and stretch the width out to fill the 16:9 space. That keeps the top and bottom composition correct, but compromises the quality (it’s about 120% width stretch) and makes everything look wide and fat. (Now that’s the way to keep a client – make them look fat! Maybe it is a way to make the point that this is not an appropriate way to get 4:3 to 16:9?). Still, there’s a good chance the client won’t even notice that the image is stretched. Seriously, every sports bar and restaurant takes this approach for their 16:9 displays and typically no-one notices. There is one difference here though… typically a 16:9 set will apply a non-linear stretch so the effect is more exaggerated at the edges than in the center. That’s not an option in NLE or compositing tools right now.

The final way to convert 4:3 to 16:9 is to consider that there’s a 16:9 canvas into which we place a 4:3 element and surround it with “something” relevant. Design elements or additional information. Place the 4:3 element in the center or off to one side to create a more balanced display. Useful for trade show type displays where the information can be useful.

But regardless of how well we work around the problem, ultimately it comes down to an unreasonable client request. How do we handle them? Same way as always… More than a small part of the job of a post production specialist is to educate clients and it seems it has been for a while now. Ever since the world stopped being “BetaSP=Professional.” That’s the problem with a diverse set of choices: it’s no longer a simple message and then suddenly it’s an “educational opportunity” with the specialist as the educator.

So, how do we deal with this educational role? Depends a lot on the client. If you have a long standing relationship with the client who’s happy with your work, then taking the “mmm, this isn’t such a great idea, here are the (unsatisfactory) alternatives” will probably work. If it’s a one-off or new client, then it’s more difficult. Then you have to feel out the client to find out what their level of discomfort is. If they’re budget focused (a very nice euphemism for cheap) then the stretched 4:3 into 16:9 solution is probably going to meet their needs. A client who cares about their public image will either realize that a 16:9 display isn’t the right solution, or allow the time and budget to find a creative solution for the extra real estate not used by the 4:3 image.
