code forr

I seem unable to get a clip to speed up and reverse.... am able to make it work in the preview, after speeding up the original clip exporting it then re adding it then adding the reverse effect. but when I do that it will not allow me to export it. ? Is there any way in fixing this with out paying for the newer version, I just bought this 3 weeks ago. ?? im not paying for a slightly newer version when this should have worked in the first place.

I am having a similar issue, Been trying to speed up a clip but ever time I try the video will just stop playing entirely, or will be stuck on one frame. Nothing I've tried seems to work, whether its attempting to speed it up before placing in timeline or after. different speeds nothing.
