How to use it
Fit inside
Keeps the whole video visible and adds margins when the new ratio differs, cropping nothing.
Fill and crop
Covers the whole new frame and crops the excess on the sides or top, removing the margins in exchange for part of the picture.
Frame rate
Kept as it was. To change the rate, use the dedicated frames-per-second tool.
Examples in practice
Landscape to vertical
A 16:9 video becomes 1080 × 1920 with fill and crop, producing a story without black bars.
Light preview
A 1920 × 1080 video is reduced to 640 × 360 and becomes light enough to load in a site listing.
Frequently asked questions
Does resizing hurt quality?
There is fresh recording, so the video goes through another compression. Lowering resolution is usually visually cheap; enlarging never recovers detail.
Can I change only one side?
The ratio is free: enter width and height. To keep the original ratio, compute the other side or use fit inside.
