some questions on colour depth and interlacing
hi.
these questions are not exactly premiere-pro specific, they are general video issues that i’ve come across and would use premiere to address. hope that’s alright.
i’ve just finished my first film for ten years. but the digital age is confusing! and i made many mistakes and bad choices which i have managed to rectify through the help and advice on this forum. so any more advice on these final issues would be a godsend.
my SD video looks great in 32 bit color space on a pc monitor. i made another version for tv, the interlacing is fine for that of course. i had to raise all blacks from pure black to value of 16. this got rid of all color streakiness and banding – great! it looks ok, but not as rich looking as my pc version because of the change to the color relationships.
Q1. now for film festivals – and video projection -i’m getting confused again. are most video projectors essentially like tv – 8 bit color, or can i get away with showing the color more like my pc version?
the other conundrum – interlacing…
Q2. am i correct in that most modern projectors are progressive and not interlaced. i noticed at the one screening Ive had so far – i got jagged lines on motion…. it wasn’t interlacing. are most modern video projectors like this? if so it would seem i have to de-interlace my movie which i know is destructive and looses quality…
Q3. if i want to show it on a pc.. again i suppose i have to de-interlace, or at least de-interlace the most offending shots…
if i haven’t got this completely wrong, shooting interlaced seems to be a nightmare best avoided.
and one last question.. what would be the best file format to offer for pc playback. i want to put a divx on the disk because it looks tremendous but i know i need to offer something more generic – but i’m just not sure whats a good format/codec that has good quality and most people could use or find the codec for? should i just make another MPEG-2??
Sorry for the list.. I would be most appreciate of any further help on any of these points…

In my opinion, if you’re calling you’re project a “movie” it should always be Progressive.
Progressive is what gives a video more of a “Movie look”, preferably shot at 24fps, 30fps works pretty good too though.
Unless you think your movie will ever run on TV I would just make it progressive (Might be too late for this projest, not sure).
If you just want to put it on a dvd for viewing, I use the HDTV 1080p preset with an MPEG2 format, the file is relatively small and it looks great on dvd. All my internet stuff is also progressive.
Hope this helps.
