Dear Stark
-Standard-def or Hi-def, or both?
Ans: SD and HD, work on both to coup up the scalibility and upcoming future demands of HD.
-What size?(aspect ratio)
Ans: When you start working on above the aspect ratio will be set according to SD or HD. 4:3 is for SD and HD I dont know.
-Frame rate.
Ans: if NTSC 29 fps
if PAL 25 fps
-File formats
Ans: DV stream is the best video file format because it is not compressed and rich. The audio is not locked.
MPEG2 is good but I prefer “DV Stream”.
-Square pixels or both?
Ans: Only Square. (infact I dont know)
-Should I add a time code to anything.
Ans: Better you provide a referance to all the broadcast devices. (Black Burst)
