I'm going to do a screening soon of a documentary film that I have been making. I've just had a look at a screening room that I'll be using , it's brand new so state of the art and they have an HDMI port to plug into at the front so I'm going to play it straight off my laptop. As it is on the big screen I want the best quality possible so I could just export at full res then play that but I'm worried about interlacing artefacts appearing during the screening. My questions are should I de-Interlace the film? Is HDMI progressive or can it show interlaced stuff no problem? The footage is DV PAL 25i.
If I do want to de-interlace then what compressor settings should I use to retain maximum quality but to also de-interlace.
I know you didn't ask for advice on this, but keep a backup ready. E.g. If you have a player with a DVD/ blu-ray running as main, keep your laptop handy - fully charged, and with the video on your drive just in case.
All the best with your screening!

Thanks for your advice. I don't want to play from DVD as I'll be losing a lot of quality with the compression that's why I want to play of the Laptop. Are projectors generally progressive or interlaced. If they are progressive I'll need to make a de-interlaced version no?
