[Paul Mowbray] “I think the original poster said he can already achieve the desired output via the standalone Microsoft encoder (I imagine via an intermediary file like an uncompressed avi) but this is not suitable for his workflow as he stated.”
Yes, this is currently my workaround for the issue but does add a significant amount of time to my workflow.
[Todd Kopriva] “I’ve filed this as a bug and asked that the arbitrary constraint be removed from the WMV exporter.”
Thanks Todd, I wonder what the new constraints will be? I do intend to render a video at 1920×2400 and have just realised that Microsoft Expression Encoder 4 limits to 2168 vertical output. I wonder if this is due to limitations of the codec?
