The created video is in slow motion

Hello, hope you're doing fine :)

Please, I really need your help!

While trying to create my video for my 1st YouTube video, the final result is in slow motion (the recording is also done slowly, about 25min for a video of less than 2min ...). I have made a video capture for you so you can see the problem, I really need your help please ... Could you help me? I have tried 2 times and nothing changes. :(

NB : I'm using the latest version of SeeMusic & I also have a pro account.

Thanks alot for all what you're doing for all of us! :)
