Is there a difference between 16×9 and 1.77:1 ?
I was asked to make two versions of a movie. One at 16×9 full frame and a 1.77 version. Is there a difference?

That’s the same aspect ratio.
16 divided by 9 is 1.77 (sometimes rounded to 1.78)

That’s what I thought. We were asked to make two versions (by a major film company). Must have been an intern filling in today. 🙂

What’s the aspect of your source material?
The reason I ask is because you can crop your image (if it’s bigger than 16×9) to 16×9 full frame. Then you can keep the aspect of your source material and letterbox it to 1.77:1

Not sure. I was only asked by my boss if there was a difference. I said they are the same and he replied that we were asked to make two deliverables as 16×9 full frame and another as 1.77. He will get back to the person asking for the two versions. 🙂

Yeah, there’s a difference but it wholly depends on your source material. If it’s bigger than HD than this is where it will come in to play.

Project was shot with Sony F900 to HDcamSR deck as 422. We captured as HD 422 and edited, CC and so on. Nothing here about SD and letterbox, anamorphic. Just a request to deliver 16×9 full frame and another 1.77 both on HDcam tapes. Mee thinx thay konfuzed.

Well, no. 16×9 full frame would be your full HD frame (since you shot HD).
But if you had a 2k frame, instead of cropping your frame to 16×9, you keep the 2k aspect ratio of the frame size and letterbox it to 1.77:1. Since you are in nothing but 16×9, you will probably only have to deliver 16×9. Hence they say 16×9 Full frame and then 1.77:1 (which would be a 16×9 letterbox within a frame of whatever your aspect ratio is that’s beyond 1080 HD).
Make sense?
