miathea 0 Posted February 15 Share Posted February 15 Hello everyone. I made an animation for a right-handed person that performs complex hand movements, from which I'd like to also create a 'faster' and 'slower' animation so the animation as well. Is there a simple way to do this in blender-avastar please? Link to post Share on other sites

File size may increase sensibly with higher fps, and there's a limit to file size for upload. The best way is to use the NLA editor, in which your animation turns into a box that you can scale in length, resulting in different animation speed. Or just plain old duplication of your animation clip and scaling the distances between the key frames. Link to post Share on other sites

Actually no, FPS manipulation has no impact on file size it is always the same, as FPS increase/decrease is not adding more info to the file it self. At least with .anim files, I don't know if there is difference with .bvh files. It might hit the time limit tho and go over 60 seconds. Link to post Share on other sites

What you see is the result from Avastar "cleanup" process, which basically retimes everything to a fixed fps based length. I wrote the export plug in for Maya that does anim file exports, believe me when I tell you that the file size increases. In my plug in I wanted a lossless output from my animations, so I did not include a under-the-hood optimization. There are 6bytes of data per frame, per joint, so mathematically fps has an impact: same visual speed of the animation, higher fps and there are physically more frames, therefore more data. If you need more details about the anim serialization feel free to ask. Link to post Share on other sites
