You may experience problem creating QuickTime 1920x1080 files with H.264 codec with the correct bitrate from HDV files.
The files you created may become 96 mbits/seconds whether you set the bitrate to 6Mbps, 7.680Mbps or 76.80Mbps.
the bitrate does change, just not the same as what you set.
|AME set to (kbps)||QT 7.1.6 reports /s||QT 7.2 reports mbits/sec|
The alternative of using the Export movie as QuickTime is even worse. Since you cannot set bitrate in that dialog box, it creates files that are 109Mbps.
It does a little better in the newer version. Setting bitrate at 7680kbps gives you 9.28Mbps
