This just came up last night on our local film/video list (Raleigh, NC area).

Someone was needing to make as “a perfect quality SD 20:9” H.264 file and could not figure out the pixel dimensions as they are “not good at math”. Advice was tossed out about letterboxing SD with no reference to SD using two difference non-square pixels nor the fact the native “20:9” footage would not be considered “SD” as it meets no standard.  Nor the fact that 2000 x 900 pixels is 20:9 etc. etc.

It’s all good to sleep through class and FB or skip the chapters if self-taught, but considering how often frame rates, sizes, interlacing etc. comes up – it seems like a career problem if you can’t solve these issues on your own.
