Are you using the CC3 Blender plugin

I think it resolves this issue...
I can't say for sure about Davinci..but it works fine when exported to Aftr Effects

Hello everyone.
I'm having kind of a big issue: I have an animated character with accu lips animations and expressions in iclone. Since this is lip synced to an existing piece of audio, timing is crucial. But when I'm exporting an fbx with the blender preset and reduced to 25fps(PAL), import it to blender via the import plugin, render out the an image sequence in 25fps and try to reallign it with the corresponding audio in davinci resolve (timeline setting there is also 25fps) the timing goes off after the first view words. After a little experimentation I found out that I can speed up the clip in davinci to play back at 104%, therefore 26fps which kinda fixes the error, but doesn't seem like the right thing to do for me, since this should be working out of the box imo... does anyone have a clue what could be the error and where it occurs? thx it advance!
