Video Lag in Preview

[Ryan5C24]

I am seeing vido lag in the preview. Never had this problem before until today. Audio runs smoothly. I have seemingly checked all the faqs and youtube and can't figure out what's going on. I put the same video into Davinci Resolve and it gave me no problems. Here are my specs

You need to tell us your source properties and your sequence settings.  Your graphics card is important and we need to know if the driver for it is up to date.

Where can I go to look that up?

[Ryan5C24]

Here are the sequence settings at the moment.

bingo....  variable frame rate...

variable frame rate doesn't play nice with premiere.

use handbrake to convert to constant frame rate

and here's a tutorial on how to use handbrake

Interesting I've never had this problem before. I'll check it out thanks.

[Michael Grenadier]

this is the weirdness with variable frame rate video, it's weirdness is intermittent and impossible to predict.  The best way to tell if it's variable is using mediainfo
