[FFmpeg-user] Convert EXR image seqs with multiple channels [AOVs] to a Quicktime

[Dan Walker]

Hello,

I'm trying to convert a set of EXR image sequences with multiple channels
[AOVs] rendered out of Houdini to a Quicktime.  The flavor of QT doesn't
concern me at the moment.

I'm just looking for a way around this. Below is my current command line
and errors associated with trying to perform the conversion.

Thanks for any help you can provide.
