That'll make it easy, because they'll be in your media pool in order. All you have to do is select all and then drag them over to your timeline. It will lay them down sequentially with no gaps between them.
You can then render the timeline as an AVI.
However, if you intend each .bmp to be a frame, go into your Options and set the default value for still photo length to one frame. Otherwise, each photo will be five seconds long, or whatever the default setting is now.
Here's what I do for sequences of JPG's or BMPs I render in Combustion. Click on the Import Media button in the media pool window. Find the folder where you have your BMPs. Click on the first image and also on the check box in the lower left corner (Open Still Image Sequence). Enter the number of the last frame in the Range box at the lower right (ie, 250 for pic0250.bmp). Click on Open and the sequence will be added to the Media Pool.
Or, you can open the folder in the Vegas Explorer window, select all, and drag to the timeline. Same effect as if they were in the Media Pool, and they will then automatically be added to the Media Pool.
In Vegas you don't have to bother with any of that, it does it automatically. When you go to import the first picture, there's a checkbox in the lower left that says "import still image sequence". Check that, and it'll bring in all the pictures as if it was a movie.
This is a 21MB Quicktime movie. It was generated by Terragen, which created 556 BMP images over a 28 hour render on a P4 2.8ghz processor with hyperthreading. Each image was rendered in 720x480 size, then brought into Vegas to be collated into a Quicktime flick. Hmm, I'm probably also post this over in screengrabs, just for fun.
Awesome clip. I used to be a bit of a Bryce junkie myself, but never used it for animation. The light quality is very nice and the water looks pretty good too. Are those all procedural textures on the mountains? Generally, they look good, but sometimes they seem almost posterized and a little flat. Very nice flyby work though--I always like the camera banking moves.
My choices of color palette were not optimal. The grass is too bright, and I could have included another couple of rock layers with differing shades of brown and purple.
I chose purple because I was looking out my window last week, and had this wonderfully clear sunset, and the Rockies all had this purple color that I wanted to replicate. I wish I'd have climbed up on the roof and taken some pics, it was so striking.
Oh well. I was happy with how the clip turned out; I didn't really put much effort into it.
