HI,
I need to find a render animation to file that will give me a video I can upload to youtube or a web page.
Whats available and where do I get it?
I have used camtasia, but thats a bit of a mess, so would like to use the render animation feature of truespace7.6. |

Hi Notejam, you can render TS animations directly out to sequential stills and then edit them in your video editing software. I use Sony Vegas, but Virtualdub is a good free alternative if you're on a budget:

You can render to a sequence of images from either the real-time renderer (fast) or an offline renderer like Lightworks (slower, but good for glass, motion blur, etc). Then compile to video in applications like Virtuadub. This lets you try different codecs etc to get better results.
You can go straight to video from an offline renderer, but this has potential problems (Cant change codec without re-rendering whole video; crash or power out during the rendering ruins the video and you have to start at the beginning, a problem if you were 6 hours into a 7 hour render and the power cuts out, etc). So rendering to stills and composite later is recommended.
HTH!

BTW when rendering to still files, don't use JPG. That's lossy compression, and then when you compress to video, you again add lossy compression, making two passes of lossy compression which will degrade the quality.
I suggest PNG, which is lossless compression. The images are much larger in file size than JPG, so go for JPG if that is an issue, but so long as your hard disk isn't on the edge of 100% full, I'd go for PNG as a good format, compressed unlike BMP, and lossless compression unlike JPG.
HTH!
