PowerDirector 365, Windows, updated. I'm editing a video. When I play it back, it stalls between clips for a second before proceeding. It doesn't do this between all clips. It seems to always do it between the same clips, but I don't see anything unique about those clips. I've color corrected. It doesn't help to render it. I haven't tried producing it yet. Thanks, tom

You should definitely try outputting your video as an MP4 to see if you see that pause in the final output.

Meantime, it sounds like you've got a resource issue.

Which processor do you have with how much RAM? I assume your media and project are on your C drive.

What device recorded your video and what is that video's resolution and format?

You say it stalls when you "play it back" but you "haven't tried producing it yet."

That actually means you're previewing the timeline content and PD has to process all the edits you've made as the playhead moves along. Some of the transitions take a lot of computing power and your PC simply isn't able to do all the processing in real time.

Reducing the preview resolution will help and more importantly, the problem won't show up at all in the produced video.

I'll try producing it. I've made a lot of videos and never seen this before. But this is my most ambitious. I do have 32 RAM which should be plenty. Thanks. tom

I have 32 RAM. I'll look at these other issues. Thanks for your help. tom

It's not how many gigabytes of RAM you have, it's how powerful your CPU is (and possibly also what kind of graphics card/GPU is installed).

You say this is your "most ambitious" project, and if you haven't worked multiple tracks or 4K content before you may not have run up against the limits of your system's performance before. Again, lowering the preview resolution or turning on shadow files may help.
