Powerpoint 2010 video
We have a Samsung 32" TV in the reception area that plays video via a usb port. Until recently, I have used Camtasia to convert Powerpoint presentations to an AVI file and then Adobe Premiere Elements 8 to get it to a compatible mpeg format. Once I'd got the format and scale right, it produced a pretty good video but not one I was 100% happy with. Some of the transitions flashed a bit and the resolution was only ok.
I have just used the 2010 video creation. I still had to use Premiere to convert the wmv file to mpeg but the results are stunning and it's a lot easier to produce. There are other utilities out there that can convert wmv to mpeg but I've got Premiere and I'm used to it.
So, for around £300, we have a signage system that does the job more than adequately. The plans are now to extend it into other areas of the school.
