Quote It seems clips where video speed is changed (in this case sped up) my preview playback freezes...comes to a dead stop. The video freezes but the audio continues. Anyone know why? I have tried all adjustments of display, hardware optimazation, etc.

Any help would be greatly appreciated.

Just how PD handles playback. Speed changes of video can be an intense process, the produced video should be smooth. If you must see it in the timeline, one option is to use render preview in that section.

Jeff, thanks for that...I will try that. Does it have anything to do with my pc? My specs:

Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz, Video CardGeForce GT 730, Operating SystemWindows 10, RAM8.0 GB

Would a better system solve this?

Thanks in advance for any help you can give.

A better PC helps, but will not solve this playback issue, particularly when a large "Speed multiplier:" is used.

Let me bother you with one more. I have used video speed quite a bit in my grandchildren's movies (they are very popular in the family!) This last project had the most speed changes, both fast and slow. I can only work for about 20 minutes on it before I restart my computer. Is that a RAM problem?

You've seen my pc specs...are there specs available that will handle all this better? In other words, should I upgrade to a loaded machine. I am retired and spend literally 3 to 4 hours a day doing this.

Thanks Jeff for your advive and your time.

You don't mention why the need to restart your computer, but I highly doubt PD RAM usage is the issue if all you have launched at the time is PD with a simple timeline with fast and slow speed changes. Launch the Windows Task Manager and check RAM usage would be an option to assess.

Ok, I'll do that. I'll let you know if there is/was something else causing this. Thank you.
