Garbage matte (correctiemasker) does not work with MPEG-4 AVC/H.264 ?

Hi,

I tried in many ways to apply a garbage mask ( 4 or 8 points) on a MPEG-4 AVC/H.264-file but correction points are not visible but even if you see the borders there are no gripping points. If a try the same trick on a .mts file it works fine.

Any idea how to solve this problem?

Thanks for any help!

Robert

ps.

- the mpeg files comes from my (very new) Olympus OM D II camera (MOV fhd, 50p frs)

- I work with elements 14
