Bug: Bitrate too low for certain low resolution .mov

[Grobe]

Avidemux 2.6.4 r8837
Windows XP sp3

When starting encoding (to x264, mp4 muxer) I imediately get this errrormessage:

Cannot setup codec. Bitrate too low ?

And of course Avidemux won't do the encoding job.

Sample video file that Avidemux fails to convert:

[mean]

It s because the video is 309 x xxxx
Resize or crop it to be at least even, preferably a multiple of 8 or 16
