[FFmpeg-user] Avid opAtom trouble

[Bouke (VideoToolShed)]

Hi guys,
Toying around with Avid opAtom mxf, generating test clips.
When I look at the clip in Avid, the bin info shows a raster dimension of 
1920x1088, pixel aspect ratio of 1.007 (expected 1920x1080 / 1.000)
And of course, when editing the clip into a seqence, frameflex kicks in.

same line but output to Mov and AMA the clip in does give the expected 
result.

Am I missing something or is this a bug?

Next, what kind of metadata besides the clip name / timecode is supported?

thx,
Bouke
