Wow, this question seems to come up almost every day. It would sure be nice to have a FAQ in this forum so we don't have to go over the same ground over, and over, and over again.

Here's a link to some advice I have given to many people:

Four rules for fast preview speed

If you search, you will find several dozen threads with additional advice.

Here are links to other threads where I gave this same advice. I am providing these in order to give you links to other threads where people were having the same, or similar problem:

Vegas Pro 10: 720p=ok, 1080p=Choke

vegas preview quality - still not getting it

Please critique my AVCHD-to-DVD production. :-)

Logan, you should update your System Specs

Logan-are you worried about the stuttery preview off the timeline or are you trying to get smooth slow motion out of the footage?

You seem to ask both questions

Might be because you're using a NTSC project and HD footage. When footage & project settings are equal you normally get the best playback speeds.

kairosmatt - yes
I'm trying to get smooth slow motion out of the footage.

All other HD clips and layers playback great.

Thanks Joran I indeed do need to update my specs.

kairosmatt - yesThe title subject of this post is: "60fps stuttering playback". I answered that question. Apparently I wasted my time posting that answer.

Sigh ...

Time for a vacation ...

Set the project frame rate to half, set the media playback rate to .500, pull the media out to full length, disable resample, and render. Done.
