Exported videos lagg with new Shotcut

So after i downloaded latest update few days ago, i have made couple of videos of games. I have exported them all few times with mp4 and avi format’s, to HDD&SSD. still after ‘‘finished’’ product is choppy and laggy… how to fix this?

pc specs: i7-6700k @4.6ghz, 16gb ddr4 2666mhz & gtx1080ti

In order to be able to assist you in fixing your concern, we’ll need a bit more information. See here for details:

It sounds like the player is not able to play them at full frame rate. You did not provide nearly enough details. Are you sure the source clips are not variable frame rate? There is very little changed from v18.07 to v18.08 that could cause this.

What player are you using to look at it? 4k footage on my laptop is beyond choppy in VLC but plays fine in windows movies & TV thanks to the support of gpu acceleration.
