Everything it does, and why
A short list, each item there for a reason we can explain.
It's already uploaded when you stop
Most tools start uploading when you press stop, so a ten-minute recording means watching a progress bar. Zoomin streams the video to storage in 5 MB chunks while you're still talking. Pressing stop uploads the last few seconds — then you have a link.
Branded intro and outro cards, burned in
Upload a title card and a sign-off once and every recording opens and closes the same way. They're rendered into the video itself by the encoder, not overlaid by a player — so they survive being downloaded, embedded, or forwarded.
It plays on a phone. Every time.
Browsers record WebM, which Safari and iOS play unreliably or not at all — and a phone is where your video actually gets watched. Every Zoomin recording is transcoded to H.264 MP4 with the index at the front, so it starts instantly instead of buffering the whole file first.
A link you can actually take back
Sharing is an explicit, per-video decision — having the URL isn't enough on its own. Change your mind and you rotate the link, which kills every copy already sent. Add a password or an expiry date on Pro.
$5. Not $18.
One price, everything included. No per-seat maths, no “contact sales” tier, no feature you thought you had turning out to be an add-on.
Real typography on your cards
Eight typefaces, nine-point placement, timing, and fade, rise or slide entrances — set once per card and rendered by the encoder at full resolution. Not a text box floating over a thumbnail.
The parts that take real work
Recording
Capture a browser tab, an application window or a whole screen, with your camera in a corner bubble and your microphone mixed in. Tab audio comes through too, so a demo with sound stays a demo with sound.
It uses the browser's own screen-capture API — nothing to install and nothing running in the background when you aren't recording. Chrome, Edge, Firefox and Safari 17+ on a desktop are all supported.
Upload that finishes when you do
Most tools begin uploading at the moment you press stop, which is why a long recording ends with a progress bar. Zoomin buffers the stream into 5 MB parts and pushes each one to storage as it fills.
By the time you stop, only the last few seconds are left to send. If your tab crashes mid-recording, the parts already sent are still there — and a sweep releases the abandoned upload rather than leaving you billed for it.
Playback that works on a phone
Browsers record VP8 or VP9 in a WebM container. Safari and iOS handle that badly or not at all — and a phone is where a link you texted someone actually gets opened.
So every recording is transcoded to H.264 in an MP4, with the index moved to the front of the file. That last part is why it starts playing immediately instead of downloading the whole thing first.
Cards rendered into the video
Upload a title card and a sign-off once and pick them per recording. They can be stills held for a few seconds or short clips, with up to four text layers each — eight typefaces, nine-point placement, timing, and fade, rise or slide entrances.
They are encoded into the video itself in the same pass as the transcode. Nothing is overlaid by a player, so they survive being downloaded, embedded or forwarded.
Sharing you can take back
Videos are private by default and stored in a private bucket; every URL the app hands out is signed and expires. Publishing is an explicit per-video decision — having a link is not enough on its own.
Changed your mind? Rotating the link kills every copy already sent, which is the only real unshare once a URL is loose. On Pro you can add a password or an expiry date.
Enough analytics, not more
You see how many people watched, and when. That is the number that tells you whether to follow up.
Repeat loads from the same visitor within an hour count once, so the figure means something. We do not fingerprint viewers, build profiles, or tell you who watched — a share link is not a tracking pixel.
