Problem with 3D graphics using AVID Media Composer

Greetings!
My team is currently working on a project in making 3D graphics using AVID Media Composer. It is such a useful program in this line of work; however, we have encountered an error on adding motion effects.
This usually occurs whenever a motion effect is added on Stereoscopic clips. Here is the error message – “A motion control cannot be created from a clip with non- native frame rate'’. Time warp effects can still be applied but my editor’s instructions were to use motion effects. We urgently need your help because we are already delayed in finishing our deadlines due to this error.
