Hey James,
I've copied the video file to my little Revo box, and he's happily encoding

The filters depend on how the video comes through, the hqdn3d filter is good
if there is low light (and therefore the image is a bit grainy), otherwise
it's best without it. Generally the yadif (de-interlace) and unsharp
(sharpen) filters are good though.

I'd recommend quitting the encoding so that you can watch it and ensure the
quality is OK (for some reason i can't play the files unless I quit and it
writes something special to the file - dunno). Finding the sweet spot "-crf"
for the lighting/conditions etc... I think 28 is the starting point but may
need lower if there is more action and especially check the slides are
readable.
