What Format, What Codec?
For Broadcast in small markets that don’t have HD I’m sure there are plenty of spots edited in SD uncompressed. But how about for projection in SD? Does anyone use DVCPro50? ProRes? DV25? HD downcoverted to SD?
Just curious if projection automatically means it will be uncompressed if it’s going to be an SD projection. How about playback formats? DVCAM, DVD or file playback?
Any of you event guys out there want to chime in?

Current projectors will detect automatically the signal it is being fed. Projectors have video (Composite, S-Video, Component and/or HDMI) and computer inputs.
DV25, DV50, DVCPro HD ProRes are all compressed formats.
To answer your question, no, the signal being projected will not be uncompressed.
I’m guessing you concerned about quality. If your original video (DV or DVD) is good quality, any decent projector will display your video very good via video input. Obviously the component input will yield the highest quality.

Also to note, displays are notorious for adding artificial artifacts to the signal path. Especially SD programming. I’ve watched my projects on all kinds of Projectors (I have a $10K Marantz VP12S4 DLP that looks amazing) Remember, there are many different types of Projectors; LCD, LCoS, DLP. They all have their strengths and weaknesses. I’ve had to explain over and over to clients why it looks great when we edit, but crappy on their cheap home systems.

A lot of smaller festivals are projecting from mini-DV and from DVD. I’ve seen both projected on fairly large screens, and it can look good if it’s been done right.

I think that statement needs to be changed to “it can look good if it is SET-UP RIGHT.” Projecting a DVD is a crap shoot at any film festival unless your DVD is set up properly from bars and tone, hooked up component out of the projector, the projector is properly set up for either interlaced or progressive, it shows proper aspect ratio etc. etc. Few film festivals take the time, have experienced enough “projectionists” or care to to set up every film they show from DVDs at a festival. I saw one of my films played via DVD at 12 different festivals, and it looked (and sounded!) different in every single venue. I use the analogy of going into to a Best Buy, Circuit City etc. and seeing the wall of tvs, every one looking different than the next. Same old NeverTheSameColor (NTSC)twice dogma apply here. Set-up is critical and most film festivals don’t have the time or inclination to set up playback properly for HD, SD, Betacam, DVD or DV. I truly believe someone could make a fortune from a simple black box that could set audio and video levels automatically from color bars and tone fed into it, specifically designed for the film festival market…
