dancingshoes, I tried to render that panoramic scene into AVI and it gave the same error, win764bit, Anim8or run in XP3 mode.
Why don't you try rendering movie in PNG pictures, then consolidate those pictures into a movie with some external program, it always works great, you can save yourself some time by rendering those pictures only once, and you can add some effects like music etc... I really like Anim8or's speed when it comes to animating, but I can't count the number of my fails when I tried to render full scene into a movie directly.
Please don't anyone understand me wrong, there are some fast codecs that render preview of the movie very fast within An8, but the full scale rendering of HQ scene is something that should be done perfect and if possible just once. When you render movie into png, even if computer crashes within rendering you can just continue from the next frame- no need to render anything twice.
Btw,
you might increase the length of your scene up to a 400 frames to look more 'fluid'. And how did you take that picture? it's great.
