SHUTTER speed QUESTION please

[BASSAM MSSALATIE]

i am having some scaning waves across the screen of (LCD ,Hdmi, R3D FILES) Something is moving from up to down or via reverse

I tried changing shutter speed from 1/48 to 1/50 . afterthat those lines went out.

The other day and with different color temprature i had them again even
with 1/50 shutter I change it to 1/32 . and it went out again , i tried 1/48 or 1/50 linesshowed up again

MY question is : IS the shutter speed related to :
1- focal lenght of the used lens ? ( when changing lenses did shutter
Supposed to be changed)
2-f stoops
3-color temprature

3-Lighting (frequency of the electric were used )

Do i suppose every time in every location , and with every used lens check for that lines or change my shutter speed ? IS THAT NORMAL ?

If you leave the shutter RELATIVE, it will take care of itself for you. Shutter is usually double your frame rate.

Thank you Shawn
Is that mean there is an option in camera to make it relative
Why it changes ..i didn't change my project settings since i received my cam last week .

Bassam, it is under sensor menu. First go to shutter, then shutter mode and chooserelative.

Try this menu map, quite an handy thing to have with RED.
