If you’re new to video pal2tech posted a great tutorial about shooting video with an X-T camera that you can view above. I am also including his recommendations below.
You should consider getting an ND filter so that you do not have to stop your lens down too much.
A variable ND filter can be very useful if you do not want to buy a bunch of ND filters
You should have a quality SD card that’s 300mb/s and 32-64gigs that’s fast enough for 4k video
Setup
Make sure you have OIS and/or IBIS turned on since some lenses need you to go into your settings to turn on IBIS/OIS and you can add +DIS is you are feeling very shaky from a lot of caffeine but it will slightly crop your image in
Shoot in 4k even if you do not need it because you will be happy you have it in the future
Set your movie AF mode to area so you can pick a focus point instead of having the camera choose for you which is what multi does
You can pick your focus point with the touch screen or nub on the back
Go into IQ and set your sharpness to -2 so that your footage looks less like smartphone footage
You should also set your tone curve, highlights, and shadows to -1
Film simulation can be anything but Velvia, bleach bypass, or black and white unless you are going for that look and if you want B&W you can do that in post because it is hard to turn B&W into color but easy to go the other way
Recommend you use Provia, Classic Chrome, Pro Neg Std.
Set mic level limiter to on
Turn wind and cut filter off for audio
Leave external and internal mic level adjustment on auto because the camera does a good job at choosing for you and do not set them to off
Lav mic you might want to manually set the mic to -20 or -15db but if conditions are all over set it to auto
Turn off auto power off in the power settings or 5 min
Set your performance mode to boost and if you have a choice set your boost mode to increase EVF frame rate for smoother video
Set auto power-off temp to high
Switch off the viewfinder and only use the rear LCD screen with the view button by the EVF
Your video settings will depend on the use case
Quick, run/gun shooting style
4k 16:9 at 30fps and 200Mbps H.265 (H.264 LPCM if your computer can’t handle H.265 All-Intra) Long GOP
Set your shutter to 1/60
Cinematic high quality footage
4k 16:9 at 24fps and 400Mbps H.265 (H.264 LPCM if your computer can’t handle H.265) All-Intra
Use Eterna with the dynamic range set to 400% which will make your base ISO 640 ISO
Set your shutter to 1/48 by setting your shutter to 1/30th and then use the rear command dial to make it 1/48th
Use an aperture of f/2 or f/4 to get a shallow depth of field
Use your ISO dial to get proper exposure
Use an ND filter if you can’t get your exposure right by adjusting ISO or stopping down
Set your white balance manually and do not leave your camera on auto white balance
It is fine to use a piece of paper if you do not have a calibration tool with you
Use Face/Eye auto-detect if you’re using the 18-55mm because it does a great job
You can make it a custom button
Make changes to your AF-C custom setting if the camera is not tracking your subject well with the defaults
Avoid using the zoom feature while shooting unless you have a specific reason because it is better to move your self towards the camera
If you do not have a gimbal practice your duck walk for stability
When panning it can be good to put something in the foreground to make your shot more interesting looking
