How the overlay is built
Your logo goes through a small filter chain before it ever touches the video: it is scaled to your chosen percentage of the frame width, converted to RGBA so transparency is preserved, and its alpha channel is multiplied down to your opacity setting. Then FFmpeg's overlay filter composites it onto every frame at the anchor you picked — corner positions keep a 20-pixel inset so the mark never kisses the edge of the frame.
Because the size is proportional rather than fixed, the same logo file reads consistently whether you are marking a 720p screen recording or 4K drone footage. The composite is re-encoded once; your audio is copied through bit-for-bit.
Marks that protect without annoying
The goal is recognition, not a billboard. Bottom-right, 10–15% width, 50–70% opacity is the grammar most audiences read as professional. Push opacity up only when theft is the actual concern — a centered half-transparent mark at 25–30% width makes footage useless to rip while leaving it reviewable, the pattern stock sites use for previews.
Watch your background: a white logo dissolves into bright skies, a dark one into shadows. A PNG with a subtle outline or drop shadow survives both. If your clip's busiest corner is exactly where the logo sits, switch anchors rather than cranking opacity — legibility comes from contrast, not strength.
Frequently Asked Questions
What image formats work as a watermark?
PNG is the format to reach for because it carries transparency — your logo floats over the footage without a box around it. JPG works too if your mark is a solid badge. The overlay is scaled relative to the video, so one logo file works across footage of any resolution.
How is the watermark sized and positioned?
You set the size as a percentage of the video's width, from a subtle 5% up to 50%, and pick one of five anchors: the four corners (inset 20 pixels so it never touches the edge) or dead center. Corner placement at 10–15% width is the convention viewers expect.
Can I make the watermark semi-transparent?
Yes — opacity runs from 10% to 100%. The tool multiplies the image's alpha channel, so a PNG that already has soft edges keeps them. Around 50–70% opacity marks ownership while staying out of the way of the content.
Does watermarking re-encode my video?
Yes, compositing an overlay onto every frame requires re-encoding, done at visually lossless CRF 23 with the audio stream copied through untouched. Processing time scales with video length.
Why watermark before posting instead of relying on platform credits?
Captions and usernames get cropped, screenshots strip context, and downloads travel without attribution. A mark burned into the pixels is the only credit that survives every repost path — and it happens here without your file ever leaving the browser.
