Colour grading that fixesflat footage
Brightness, contrast and saturation with independent control over your main footage and your B-roll — plus a dramatic grayscale look when the video wants to be cinematic instead of colourful.
How to use the video colour grading in three steps
Mixed sources are the reason most edits look amateur: your camera footage is warm, the stock clip is cold, the AI B-roll is oversaturated. Grading them separately is what makes a video look like one thing. Shorz keeps the controls where you're already working, with independent values for the main video and the B-roll.
Set the exposure
Brightness runs from 0 to 2× — lift underexposed footage or pull back a blown-out window without leaving the panel.
Brightness 0–2×
Add contrast and colour
Contrast separates the darks from the lights; saturation decides how vivid the colours are. Push both a little and flat phone footage starts to look intentional.
Contrast & saturation
Match your B-roll to it
B-roll has its own brightness, contrast and saturation values, so imported clips and generated visuals can be graded to sit with your main footage instead of jumping out of it.
Separate B-roll grade
Find it in the app under Settings panel → Video Colors · Dramatic Grayscale.
Why Video Colour Grading in Shorz
Dramatic grayscale, applied by AI
One switch turns the video into a stylish black-and-white with a cinematic mood — the app applies the look rather than handing you six curve controls to fight with.
One-switch look
Part of the same style pass
Grade, border, overlays, captions and titles are all set on the same project, so a channel look is a set of numbers you configure once instead of a preset you re-apply every time.
Channel consistency
Who uses it, and for what
Phone footage

Mixed sources
Make stock, AI and camera clips match.
Dramatic edits
One-switch cinematic black and white.
Brand look
The same grade on every upload.

Video Colour Grading questions
Brightness, contrast and saturation, each ranging from 0 to 2×, with independent values for your main footage and your B-roll. There's also a dramatic grayscale effect for a cinematic black-and-white look.
Yes — that's the point of having two sets of controls. Imported and generated B-roll can be brought in line with camera footage so the video reads as one piece.
No. It renders locally, so it's free on every run including the free weekly allowance.
