3840X1634 RESOLUTION (2.35:1 CINEMASCOPE/ANAMORPHIC ASPECT RATIO) | VIDEO BLACK BARS | TEST+TUTORIAL

*ORIGINAL FOOTAGE (IN-CAMERA RECORDING): 16:9 ASPECT RATIO (1.78:1 ASPECT RATIO), 3840X2160 4K UHD FORMAT/RESOLUTION.
(*= let's assume, this footage is the 1080p UPSCALED 4K which was used in our before 1080p CINEMASCOPE example.)
FINAL FOOTAGE (AFTER POST-PRODUCTION): 2.35:1 ASPECT RATIO, 3840X1634 4K UHD RESOLUTION.
TUTORIAL (FOR 2160p IN-CAMERA RECORDING 4K UHD FOOTAGE):
A. TRADITIONAL METHOD
B. MODERN METHOD
......
A. TRADITIONAL METHOD:
1. YOUR CAMERA RECORDS IN HD FORMAT/RESOLUTION OF 16:9 (1.78:1 ASPECT RATIO) AT 3840X2160 VIDEO RESOLUTION, YOU HAVE TO CONVERT THAT FOOTAGE TO 2.35:1 ASPECT RATIO AT 3840X1634 VIDEO RESOLUTION.
2. TAKE HELP OF 2.35:1 ASPECT RATIO BLACK BARS (YOU CAN EASILY DOWNLOAD FREELY FROM THE INTERNET) TO PROPERLY POSITION YOUR FOOTAGE IN THE TIMELINE. (or MAKE USE OF 'ADJUSTMENT LAYER' BY CROPPING IT'S TOP AND BOTTOM EACH BY 12%, make sure to make this 'adjustment layer' invisible at the time of EXPORT).
3. IMPORT ONE FOOTAGE OF YOUR IN-CAMERA NATIVE ASPECT RATIO/RESOLUTION IN YOUR 'PROJECT', DRAG AND DROP THAT FOOTAGE IN YOUR 'TIMELINE'. THIS AUTOMATICALLY CREATES THE 'SEQUENCE' OF YOUR 'PROJECT' BASED ON THE ASPECT RATIO/RESOLUTION OF YOUR FOOTAGE IN THE 'TIMELINE' or YOU CAN DO THIS MANUALLY ALSO! THIS 'SEQUENCE' SETTINGS OF YOUR 'PROJECT' IS WHERE YOU EDIT ALL AND FINALLY EXPORT TO AS IT IS (BUT IN THIS OUR CASE WE ARE GOING TO MODIFY TO MAKE 2.35:1, more in other steps).
4. PLACE YOUR 2.35:1 BLACK BAR/CROPPED 'ADJUSTMENT LAYER' OF STEP 2 AT THE TOP LAYER OF ALL IN YOUR TIMELINE, AND LOCK IT (SO THAT YOU CAN'T EDIT IT!).
5. IMPORT ALL YOUR FOOTAGE IN THE TIMELINE NOW. EDIT AS YOU LIKE!
6. NOW, WHILE EXPORTING:
i) MAKE YOUR 2.35:1 LAYER/CROPPED 'ADJUSTMENT LAYER' INVISIBLE.
ii) AT 'EXPORT' WINDOW WHILE EXPORTING:
a. CROP 263 PIXEL TOP, 263 PIXEL BOTTOM or 12% TOP AND 12% BOTTOM ON SOURCE FOOTAGE. [or 'NEST' your whole source footage of 'sequence' you're about to export in the 'TIMELINE' and 'crop' (optional) as desired amount, adjust frame/s if necessary and change 'sequence settings' video resolution to 2.35:1 ASPECT RATIO (adjust frame/s if necessary).]
b. ADJUST THE FINAL VIDEO RESOLUTION OF OUTPUT FOOTAGE TO 3840X1634 AT 'EXPORT' WINDOW. (no need if 'or' step of 'a' is done)
iii) NOW, EXPORT YOUR VIDEO!
7. FINISHED!!! :)

SOME MATHS IF YOU'RE INTRESTED (FOR 2160P IN-CAMERA RECORDING 4K UHD FOOTAGE):
ORIGINAL FOOTAGE (IN-CAMERA RECORDING):3840X2160 4K UHD RESOLUTION
3840/2160=1.78 or
ASPECT RATO= 1.78:1 or (16:9 ASPECT RATIO, 16/9=1.78, 1.78:1)
BUT, WE WANT ASPCT RATIO OF 2.35:1
SO,
3840/2.35= 1634 PIXELS (ROUNDING)
2160-1634= 526 PIXELS
526/2= 263 PIXELS (VERTICAL HEIGHT TOP AND BOTTOM BLACK BARS SIZE; TOP=263 PIXELS AND BOTTOM=263 PIXELS) [FOR % TOP AND BOTTOM BLACK BARS SIZE: 263/2160X100%= 12.176 % (ROUNDING)= 12% (APPROX/ROUNDING), TOP=12% & BOTTOM=12%]
HENCE,
THE FINAL OUTPUT FOOTAGE VERTICAL HEIGHT CROP: TOP=263 PIXELS AND BOTTOM=263 PIXELS or TOP=12% & BOTTOM=12%
THE FINAL OUTPUT FOOTAGE EXPORT VIDEO RESOLUTION: 3840X1634
......
B. MODERN METHOD:
1. DIRECTLY SHOOT IN-CAMERA AT 2.35:1 ASPECT (take help of guides).
2. CREATE 'SEQUENCE' AND CHANGE 'SEQUENCE SETTINGS' DIRECTLY TO MATCH YOUR ASPECT RATIO AND FPS (2.35:1 ASPECT RATIO in our case here, FPS as per your footage shot in).
3. MAKE ADJUSTMENTS IN THE EDIT FOR YOUR REQUIRED FRAME POSITION (if necessary).
4. EXPORT DIRECTLY!
5. FINISHED!!! :)
......
GUIDE:
FOR 2160p IN-CAMERA RECORDING 4K UHD FOOTAGE 2.35:1 ASPECT RATIO CONVERSION
SOURCE RESOLUTION= 3840X2160 4K UHD
OUR INTENDED OUTPUT RESOLUTION= 3840X1634
SO,
CROP TOP AND BOTTOM OF SOURCE AT RENDER BY 263 AND 263 PIXELS RESPECTIVELY.
or
CROP TOP AND BOTTOM OF SOURCE AT RENDER BY 12% EACH.
AND,
CHANGE FINAL OUTPUT EXPORT RESOLUTION TO 3840X1634.
