Hello everyone, this is my first time here and i NEED help!
 
Im using matchmover pro 4 and need some help, i import HD footage into it from the sony fx1 and i set all the track points but the only thing missing is filling in what the film back width, height and focal length.
 
i looked in the manuel to the camera and it says the following
 
"Focal length  
4.5 - 54 mm (3/16 - 2 1/4 in)
when converted to a 35mm still camera
32.5 -390 mm (1 5/16 - 15 3/8in)"
 
can anyone please tell me what i should type in matchmover for the following?
 
what should i type in for "Film Back Width"
what should i type in for "Height"
&
what about focal length??
 
i also have one more question... i feel stupid even asken... but when i import footage into matchmover pro 4 from my sony fx1 it says 720x480 but i swear i shot it in widescreen! and when i look at the footage is all stretched upwards... in the ratio box it says 1.5 but in the squeeze box it says 1 when i change that to 1.5 it looks normal to me... is that what im supposed to do?
 
anyways, i really hope someone will take the time to help me!
