Video Issue when selecting a Ramp Change in Tempo Track

When I apply a Ramp change in the Tempo Track, it always affects the Video I’m scoring by slowing down it’s frames rate, making it like a slow motion video (3-4 frames per second for all the length of the ramp).
It’s like the ramp directly changes the video fps itself.
What am I doing wrong?

Thank you in advance.

This could be caused by one of two things. 1) The video track isn’t locked or 2) the video track is set to musical base rather than time base. To lock the video track, click the little symbol that looks like a padlock on the track. To change to time base, find the button on the track that looks like a music note; clicking it will turn it into a button that looks like a clock. This should solve the problem. (You may want to remove your tempo changes before doing this. Locking it might cause the frame rate changes to stick. I’m not sure.)

You suggestion worked perfectly, really thank you!
