Change Video Clip Speed in DaVinci Resolve 18.5 (and Reverse Clips!)

When I render exported timeline, the clips I’ve changed the speed on do not export any audio… any ideas how to fix that?

You can do it only for video but not for images?

Can any tell what is 3 button mask in fusion

the problem about da vinci 18 is when u change the speed it changes the frame rate automatically even I have a 60 fps clip , when u dropping the clip the timeline it ask change the frame rate or not after that it locks the frame rate it doesn't matter you have a 60 fps .it keeps the frame 24 when u change the speed its something so stupid in da vinci 18 .is there any solution

I’m using MacBook so when click S it’s not doing it ?
