Video capture of still pictures

Does anyone use a video camera for live capture during print talks and competitions? At this time my club uses a DSLR to capture the still images to project during a print talk. We need to do this because we have such a large audience only a small number can see the prints live so projection to a large screen is needed. We have considered that video capture using a suitable mirrorless camera might be a good option. We would not need very high resolution but will need good colour and tonal representation. Running in a video mode for 90 mins or so does risk overheating and rapid battery drain. Any feedback from experience would help.

I can see why you don't want to project original JPEG / other digital files as print competitions are all about the print, including the choice of mount, paper etc.
Photograph the mounted prints, project the photographs at the same time? You might need to persuade the judge to use a laser pointer and point out things on the big screen instead of on the actual print.
If you go down the live camera route you will run into heating and battery problems when using most dslr or mirrorless. If you go for a conference camera like these type then you can even livestream so that members can watch from their devices or at home

Thanks Chris an interesting link. It is more about visiting speakers which we try to persuade to either bring JPEG copies as well or be prepared to hand prints around but some are unable or unwilling for various reasons. For actual competitions, it is not a problem as they have to also enter a JPEG version of the print as well. in this case the judge ignores what is on the screen. However, providing members have a calibrated workflow, the projected versions do look quite good though not quite the standard of prints.

If you only want to show the printed material and not the judge / speaker then get a document camera, they are pretty bloody decent nowadays, easily connect to laptop to project live or capture snapshots, possible to zoom in on areas too. I've used this before with someone who has MS and needed paperwork, photos and certificates quickly projected large Doc Camera
