Best quality for projection ina lecture theatre
on Feb 28, 2012 at 4:31:32 am

I have a number of medical projects that will ultimately be projected on a large lecture theatre screen.

Can somebody suggest a workflow to end up with the best quality for audio and video both by playing via a PC and a DVD player.

I've tried searching the archive without any great success. I have exported various Quicktime movies and Quicktime Conversions and burned them to DVD however the image resolution isn't fantastic - even of files of about up to about 3GB.

My priority is to get best quality playback vis a PC/Mac laptop.

Any help will be greatfully appreciated.

Kind regards

Eamonn

[Eamonn McNulty] "Can somebody suggest a workflow to end up with the best quality for audio and video both by playing via a PC and a DVD player."

The limiting factor is the resolution of the playback device. If you're playing a DVD, you're limited to PAL's 720x576 or 720x480 in NTSC-Land.

It doesn't matter how detailed the original video is. That's what you get.

If you play off a laptop which feeds a projector, the resolution of the projector becomes the limiting factor.

Since you haven't really established the ultimate playback device yet -- or you may not yet have the necessary information -- it's difficult to give a definitive answer.

Thanks for your helpful response Dave.

Kind regards
