Compression for broadcast – am I doing this right?
Hi folks,
A documentary we produced has been picked up for broadcast, which is my first foray into TV since I quit that industry 4 years ago to set up my little web video business.
We shot at full 1920×1080 HD, but the broadcaster is asking for 720×576 full height anamorphic. For the pixel aspect ratio I’m selecting PAL CCIR 601 (16:9).
The resulting export is contained in a 4:3 box with no letterboxing and the picture ‘stretched’ vertically. Does this mean the broadcaster will then ‘correct’ the image for transmission or am I doing something wrong?
Cheers in advance!

Did they give you any codec information?
What player are you using to play the file? -
Hi Craig,
ProRes422, DV-PAL, 8bit uncompressed or 10 bit uncompressed are all acceptable. I’ve tried ProRes so far and used QT7 to view the output.

Hi,
Compressing in DV-PAL anamorphic has done it – now displays in the proper aspect ratio.
Not sure what the pixel resolution would be if I did want to use ProRes though…
Thanks anyway!
