I can also tell from that still grab, you have a lot of audio problems ahead of you.
Do you really mean this is going to be a “PBS” show, or do you really mean “local cable access TV”? I’m beginning to think you really mean Public Access and not PBS.
I’ve been looking at a “standards” document on deliverables, from one of the Cable channels we ship public access programming to, from our shop. Your mileage may vary, of course. You can look this up on the web site for your particular local cable company under “public access production information”, or something like that.
Their Cable standard around here calls for an mpeg 2 file in 4:3 aspect ratio, (let’s do the time warp again!) for their access channel programming. You can tell by this, they give up free bandwidth to serve the public only grudgingly and under duress. It’s literally the least they can do, by law.
They go on to say in the list of deliverables, you can letterbox your wide-screen programming to fit that 4×3 box, and if you shot wide-screen originally, that’s what I’d suggest you output as, letterboxed 16×9 inside a 4:3. If you submit a full-frame wide-screen, they say they will squeeze it to fit 4×3 and that looks terrible, even if a viewer adjusts their TV at their end to “un-squeeze” it. I wouldn’t count on viewers to know how to be able to do that, so I think your best bet is the letter-boxing. Their last suggestion is to crop the 16:9 to a center-punched 4:3, but unless you shot everything with that in mind, it’s going to look horrible. I have had to think this thru for my own shows, and basically that’s what I’m doing: is shooting wide screen but “protecting” for 4:3. That is, I make sure the very most important stuff stays in the center 4:3 marker zone. Then I master the program as two distinct edits: the high def, high quality, 16:9 version for YouTube and Vimeo, etc., and the 4:3 pauper version for Comcast. These days I’m pretty sure the YouTube one is going to get seen more. That’s not my fault. That’s because commercial pressure to kill Public Access drives the standards.
Most letter-boxing is black, top and bottom. But I don’t know for sure that that’s mandatory. Which means there is space in that real estate for some “branding” graphics, if you’re feeling “sporty”. Nothing that would distract from the content in the middle, of course. But a soft, tone-on-tone logo of the show name could go there, and even phone/ web info or the dates of the next broadcast.
