Hi,

What is the best way to convert from 16:9 FHA to 14:9 LB in FCP. Is the best way to distort the 16:9 FHA (in 4:3 Seq) to get 16:9 LB and then scale up? Surely this is not the best way and will lose more information than is necessary? Is there a way to scale down from 16:9 FHA straight to 14:9 LB without going to 16:9 LB first.

Ideally we would use a hardware ARC but we don't have that luxury.

N.B. FHA - Full Height Anamorphic, LB - Letterbox (some people call what I call 16:9 LB, 4:3 LB but I hope I have been clear enough)

Any help would be greatly appreciated, I need to do this layoff in about 15 minutes...

    Use Compressor and set it up for letterbox.
    You could make a new sequence with the settings you want (4:3 I think you were a bit confusing with all the secret codes) and then put the 16:9 anamorphic material sequence into this new one. It should letterbox itself but if not then drag it into the viewer from the new sequence and use the Motion tab to change it's aspect ratio.

    That's fine to make 16:9 LB but I need 14:9 LB which is midway between a 16:9 FHA > 4:3 FF (Centre Cut) and 16:9 FHA > 16:9 LB (Deep letterbox).

    I was going to do this is After Effects but I don't really have the time to render.

    I was just thinking there was a better way than using distort to make 16:9 LB then scale to 14:9 LB.......perhaps not...

    Well you lift I say elevator You say distort I say displayed in the correct pixel aspect ratio.

    If you letterbox something usually the actual output is 4:3 the picture area is part black part useable information. So make a 4:3 program with you 16:9 material scaled to the correct pixel aspect ratio and scale the whole image to get 14:9.

    That is actually what I said in my first post. I wanted to know whether this is the most efficient way of doing this (in terms of video quality) because when you 'make a 4:3 program with you 16:9 material scaled to the correct pixel aspect ratio' you are losing vertical image resolution / video quality, which you then scale...
