Camtasia With Tiktok

Greetings Guys, please am writing to get possible suggestion on how to make and do the setting on camtasia studio (8) to enable me to produce tiktok videos.

This seems viable but the one i made was compressed at the middle, thus, leaving a lot of spaces at the top and below: https://www.screencast.com/t/Xlc5H1AXHCO0

As you may know, TikTok has video dimensions size of 1080×1920, i have already set up this recommended video dimension or size, but the outcome is not coming out well, as seen in the above link., i just want the main video to cover in the whole canvas.

Please how can i make it to cover the whole canvas as tiktok dont want it in the present form?

Any suggestion or tutorial to achieve will be appreciated


Thank you

try using a power point instead, then set it to the 16: 9 dimension
