Looking for editing software that can:
1. Edit HD video and burn to Blue Ray.
Sony Vegas Pro 8 can burn to Blu Ray. Full Blu Ray authoring however is not yet offered by Sony but is expected to be in a future release of DVD Architect.
2. Combine HD clips, stills, and text for slide shows. (Understand BR can only be played on BR players)
If you just mean a video of these things in sequence then Sony Vegas Pro is very good at this. Other NLEs too. If you mean an interactive slide show that advances when the user clicks then you'll have to author that with something like Adobe Flash and it's going to be heavy going.
3. Where to load still slideshow with HD video clips for public viewing?
If it's just a video slideshow you want to host then check out the following:
hdvundersea.com (from our very own Wags - 480px wide)
vimeo.com (can take higher resolution videos)
brightcove.com (480px wide)
veoh.com (the late Stage6 is now sending users there)
blip.tv
The most popular sites for interactive stills slideshows seem to be photobucket.com and slide.com but I dont know if they can include video and the size is small.
I have a website. Is there a program that will create a slideshow with stills and HD clips that can be saved in a format/file that I can load to my website that people could download to view?
Video slideshow: Just about any NLE including Sony Vegas Pro
Interactive slidewhow: Adobe Flash Pro (or alternatively something to author a new Microsoft Silverlight thingy). Steep learning curve! HEAVY GOING.
Can it contain HD clips or do I have to down size to MPEG1?.
Forget old MPEG1. There is basically no limit on resolution on any of these formats I mentioned. Flash video, WMV, DivX/Xvid or whatever you choose can go up to 1920 x 1080 but of course you'll need a lot of bandwidth to download. For high quality web delivery I like a resolution of 960 x 540 which is half the height of HD. Here is the method I use for Xvid videos.
