Hi Politcat
Thanks for downloading trakAxPC.
It sounds like you are trying to mix piece of video which is wider than its height and so looks stretched in the Video Output Screen. You can click on the preserve the video aspect ratio button in the video output screen and the video should look much better. You can also stretch the screen by clicking on the stretch button.
I have included a screenshot:
Once the file is rendered trakAxPC automatically preserves the aspect ratio regardless of whether you clicked this button or not.
If you are still having this problem, please send me the file you are having an issue with I can have a team have a look at it over here.
Best regards and thanks
Cormac
