HD formats, frame sizes and timecodes demystified…
Posted by Greg Nosaty on August 5, 2009 at 11:24 pmHas anybody on the list either written or come across a “definitive guide” to demystify HD formats, frame sizes and timecodes? A document that would explain things like why DVCPro 720 is 960 x720 (anamorphic) and not 1280 X 720 like the others, or why FCP ingests 24p media as 23.98 if it is a non-drop format…

August 5, 2009 at 11:32 pmPanasonic uses 960 as a way of compressing the data. The video frame rate for 24p is 23.976. Final Cut calls it 23.98, but it is actually 23.976. Drop frame and non-drop frame has nothing to do with the actual frame rate. It is only how the frames are counted.
All the best,
Tom

1)Because Panasonic is cheating HD resolution by using an anamorphic trick. It really is 960 pixels – you gotta strech it out to fit 1280.
2)98% of 24p media is actually 23.976 media, and 98% of workflows should conform to that. DF and NDF are simply counting methods. They don’t affect the amount of frames

MOST formats “cheat” their resolution. HDV is 1440×1080…not full 1920×1080. JVC HDV is 960×720. A majority of HD tape formats are anamorphic. That is how they compress the footage to save space.

True, but they sure mess with getting proper show times…ACTUAL length of a show. NDF isn’t time accurate, DF is.

Unless this has changed JVC shoots full 1280×720. I think only DVCPRO HD shoots 960×720. Who knows, there’s going to be another format next week anyway.

August 6, 2009 at 12:09 amThere I go, talking about something I THOUGHT I knew about, but didn’t.
I guess they save space by compressing to that horrid GOP compression then. Ugh.

August 6, 2009 at 12:29 amShane, thanks for the link to Phil Hodgetts.
Here is graphics questions to go with the anamorphic HD formats. Say you were going to make graphics for a project shot in HDV would you work in 1440×1080 rectangular pixels or 1920×1080 square pixels? Or a DVCPro 720p project would you work in 960 x 720 rectangular pixels or 1080 x 720 square pixels? Presuming we are importing and editing in FCP.
