Thanks Francois,
Can’t see my original post here so am a bit in the dark.
The avi option was greyed out because it is a drop-down but it doesn’t tell you that. By trial and error (basically mouse-bashing) I got the drop-down menu to drop where it gives you the detailed avi options which are not greyed out ☺
Filters are okay at the moment – have used brightness and colour correction plus a 3rd party deflicker demo filter – all have rendered alright so far.
My source is captured home-movie cine, it is also experimental footage, not straight regular visuals.
How do I select 3:4 ratio in Vegas please, I use old cine cameras with original lenses so it’s all 3:4 format.
Thanks again,
Ric
