Solved Constant crashes & lockups in Vegas Movie Studio

Hi again, Sorry for posting but having real bad issues with movie studio. I have a few clips on the timeline in sequence and all seems ok but the video preview keeps on running like 2fps every so often. I tried to insert a transition and the preview window locks up and the Pc became unresponsive where I had to shut down the PC to re start the program. I tried altering the video RAM cache and lowered the preview window as low as possible but it seems that any effect or transition causes a "not responding" icon to appear and I am forced to restart the windows to get out of it. I removed all effects and transitions as they seem to be a problem or is this normal behaviour for a very buggy program? I have a good PC and not sure why any kind of preview causes excessive stuttering on the preview window regardless of resolution set. Thanks for any advice!

What are the specs of your "good pc" and what graphic processing are you using.

Specs for PC are;- Win 10. CPU: Intel i3 8100 3.6Ghz Quad core . Chipset: Z370 . RAM: 24GB DDR4. Graphics: 1060GTX 6GB . Drives: 256GB solid state. 2TB 2nd. 4K monitor. Boss ME80 digital sound interface. 16Watt PSU.

There is nothing wrong with Vegas Movie Studio Platinum 16 !

Intel i3 8100 is a lower powered CPU and not the type of CPU suitable for heavy duty Video Editing.
There is nothing wrong with your CPU, however an i5 or i7 is the type of CPU you really should be using for video editing.

Don't start mucking around with the RAM cache in Vegas.
It is best to leave this at the default value. Increasing the amount available will in fact make the Preview window worse.

I see in your computer's specs that you are using a 4K monitor.
If you are trying to edit 4K video with an Intel i3 CPU, it is not going to work!
You need to be using an i7 CPU if you want to edit 4K video.

The type of video you are editing with can have a MAJOR effect on how the Preview Window works while editing.
You MUST make sure your Project Property settings match the type of video you are editing with, otherwise you will experience extreme lag.

I recommend you read/watch this tutorial, for how to reduce video lag while editing.

thanks for your reply but just to clarify, the i3 8100 is an 8th gen 4 core cpu equivalent to the 7th gen i5 7600 in performance (excepting turbo). I do not consider it weak as such and is far better than the older i3's but understand that an "8th gen i7" would be very nice and something I am budgeting for!
