Just Play
I have a strange problem: I got a movie of about 30 minutes and we’ll have a premiere on sunday. My file is from AVCHD (Panasonic Lumix GH1) and in HDTV 1080p 25fps it’s about 7gb large. The problem is: On our premiere, I’ll have to play it from my computer via HD-Beamer, and there will be about 200 people – don’t ask. How can I be sure it’ll all work? It’s a 2,53ghz @ 6gb ram. It’s a silly problem, I know, but I don’t sleep…
Thx a lot! -

If your Premiere is important, don’t.
First on the projector, if you are the one picking the rental, forget 1080p. The trade off with cheap 1080p projectors is the brightness. The one you mentioned is 1000 lumens, which very dim for about any application, especially video playback. If you have control over that part of the event, rent a lower resolution projector (usually 1024×768) 3000 lumens and up. 1000 lumens will work in total darkness, but the contrast ratio is likely to be pretty awful.
For playback, relying on Premiere just isn’t a good idea, and on top of that, you are not getting full playback quality. I would burn to DVD at maximum render quality, or have a laptop playback backup.

I should rephrase, that I am assuming you are using the 1000 lumens HD version that I’ve seen in many places.

A small part came up wrong, due to foreign language: I will not play from Premiere, I will take an mp4 – or what you recommend! We will have two beamers: one is 1024, one HD – I don’t yet know the second one, but the first one gave it all out too green and too brown. And we will pay for the rented 1080p… So the question will be: How to export? How big may the file be? Which programm will I use? I thought about burning a blu-ray, but yet the burner crashed. Just imagine an opening night for a small happy-friends movie with 200 producers, directors and actors surprisingly coming.

Got it, you have few options for export. Mp4 is a good option, (H.264). Depending on how fast the machine is, you could start with 4Mb/s as a bit rate. I would still have a back up. The other option again is Bluray. If you are having issues with crashes, I would try creating disc image (ISO), then burn that directly to the disc using Win 7 on any ISO burner software.
On the projector, I would look at rental houses around and see if you can get a Sanyo or Panasonic 3000-4000 lumens. You’ll get much more bang for your bucks.
Good luck!
