So I've created a mask and ive tracked it to follow my movements from 8 seconds into the video onwards. I want to apply an effect the mask starting at 8 seconds, however when i add it, it does it for the entire video (still in the masked area which is what i want but not for the entire duration). Is there any way I can start the effect at the 8 second mark for my masked area? Thanks in advance
If you add an effect to a mask using compositing options, all you have to do is keyframe the mask opacity.
In this example I added a rectangular Mask to the last word, add Gaussian blur to the layer with the blur set to about 80, added Compositing options to the Gaussian blur set to Mask 1, then added a Mask Opacity keyframe at about one and a half seconds to 0% and another one at about two and a half seconds to 100% to get the Gaussian Blur to animate.
The result is the same as if I had animated the blur, except that the blur only affects the last word.
ok thank you for the explanation I'll give this a go i didnt relase you could adjust the opacity for each frame! I am trying to recreate this video effect as best as I can so if you have any effect suggestions let me know!
