Layback to Digibeta format?
I’m Laying back sequences to Digibeta tapes, and i’ve long been wondering the following:
1. Am i using the best format to do this?
-We use uncompressed 8+10 bit, but they’re huge files, and hard to store. I know there’s been a great development in formats lately, so i might want to go somewhere new with this.2. If you create a 16:9 letterbox format on the digibeta, will the 16:9 televisions “crop” the letterbox away, and show full frame?
What happens if you do a layback of a 16:9 fullframe to digibeta, and forget to put on the “16:9 anamorphic” switch?

Hi.
1. you might want to explore ProRez HQ
2. normal tv does not crop and you should use anamorphic instead
it depends on your output device what it does what anamorphic

Then… would’nt i just be better off to forever swtich on the anamorphic?
Wheter it’s a 4:3 or a 16:9?
Then i suppose it will anamorph itself to adjust to viewers tv?

Not for standard def, in fact not for anything 10bit or less. ProRes is what you want to use. There is zero reason to use anything but ProRes for 8 and 10bit files.

“No, a TV cannot automatically switch an anamorphic image to Letterbox. This is done by the playback device.

Always go with the delivery spec that your clients asks for. If they haven’t told you how they want it, ask them.Richard Sanchez

Walter, I love when you say things like this because I know it’s coming from a place of intensive testing and analysis. Can you elaborate at all on why ProRes (SQ) is not a tradeoff compared to “Uncompressed 10-bit” for SD? Is it really lossless? How about HD – specifically, ProRes vs. ProResHQ vs. Uncompressed for 10-bit 1080? I realize this may be asking much, but blame yourself, you sparked my curiosity…

HI max,
i kind of depends on your footage format and your delivery format. Most broadcasters specifiy DigiBeta or HD delivery (some just DVcam). Then look at your footage format.If you are shooting DV and delivering digibeta, stay with that all the way to the final sequence then change the render settings to Uncompressed SD or prores (but i imagine you wont see that much of a difference with ProRes)
If you are shooting DV and delivering HD then you might want to look at capturing to ProRes and rendering the final sequence that way.
If you are shooting and delivering Digi then stay uncompressed SD all the way, and maybe render the final sequence as ProRes.
As for widescreen, again it depends on the broadcaster delivery requirements, but most people nowadays want FHA (full height anamorphic) . So full screen, no letterbox. It is the broadcasters job to sort out transmission to 4:3 tvs. They often letterbox it to 14:9 here in UK.
cheers

Then should it be square pixels? Or PAL CCIR 601?
I have no idea what the difference really is?

PAL CCiR 601.
Square pixels are used for graphics, web delivery etc.
