VBR, 2 pass in After Effects (mp4 / h264)

Please add VBR, 2 pass export from After Effects (mp4 / h264).

Reasons:

1. Exporting / rendering directly from After Effects is much faster than from Media Encoder.
2. Washed colours and other ocassional issues when trying to export via AME.
   3. Smaller files size of VBR 2 pass files.
