I recorded a presentation using powerpoint. But when I present again using the same slides, my speech and timing have been recorded. I am able to delete the speeches but the slides always automatically flip to the next page following the timing of my recorded presentation. I tried using Slide Show tab -> uncheck Use Timings. But the timing information is still there. Is there anyway to remove the recorded timing?
OK - this one's pretty quick and easy... so despite the fact that this isn't really a graphic design question, and that we're neither a tutorial service nor a stand-in for any one software manufacturer's tech support or training...
Click "Record Slide Show" in the Set Up section of the Slide Show tab; point to "Clear" and choose what you want to delete - in this case you'll select "Timings on All Slides."
Edit: On PowerPoint 2016 for Mac (per OP's Comment below) there is no equivalent drop down - the trick here is to go into the Set Up Slideshow tab and switch to manual timing, then close that dialogue. Then you can re-record the slideshow to set new timings if you need to, or of course you can just run manual if you'd prefer. There isn't a directly equivalent "clear all timings" on the Mac version thanks to Microsoft's continuing push to be sure that people using MS Office on Mac get a clear message (they think the message we hear is 'Mac sux', what we actually hear is 'MS is duplicitous and hasn't stopped with chicanery yet') though there is no technical reason they couldn't provide an exact equivalent if they chose to.
Hope that helps.
Running manual didn't clear timings from my custom (looping) show. In fact, unless timings are cleared, the few looping/timed slides will hold presenter view hostage—even if you delete the custom show, which I did.
Brad's answer pointed me over to Transitions. My After checkbox wasn't checked but with those few looping/timed slides selected, I just checked/unchecked the box anyway, and that freed them up and cleared the timings.
