Hey guys, I got a few raw animations on iclone8 recorded with mocap tech, when you export from iclone8 there is an option to export with different frame rates for the fps (60, 30, 25, 24, 12), when you export with less frame rate you expect the lnegth of the animation to change, and thats seen on the files when you inport them to blender after exporting from iclone8 with less fps, (a anim with 60 fps if exported with 30 fps will have half length duration), thats what we expect, but this same exported file out of iclone8 with less fps will have the same length duration on unity besides in unity it shows it has less frames but the length dont change, if the anim originally had 5 min of length, it will be exact of the original in unity regardless the fps! This is good bc we can save storage exporting the anim with less fps, but will be bad for future polishment and touches on blender since it will reduce the length on blender but not in unity. My question here is, is that normal? what causes this behaviour, is there a way to export it this way in order to save storage on size of the anim files and make it a workable file in blender considering on blender it will have less length and therefore less speed than whats shown on unity? Also is there any further possible problems in this pipeline? Thank you !

Not sure about Unity, but Blender does not reduce/extend the duration of the clip regardless of the FPS you export with.
It displays number of frames according to FPS exported from iClone, but the duration would stay the same.
You may verify that by hitting Ctrl+T switching timeline from frames to time display (need to click on timeline first).

Same is true for iClone BTW. If you switch FPS in Project settings you'd see number of frames changed on timeline, but the duration is always the same.

iClone - 60 FPS - selected frame 480, time 8 sec


12 FPS FBX Imported to Blender - same position at frame 96



But the time is still 8 sec.
