Original-file hosting. No built-in video player for this container.
A 3G2 file opens in Flat's download view. It does not use the built-in video player, even when some of its codecs are familiar to the browser.
3GPP2 files are associated with older mobile and CDMA workflows. The actual codecs depend on the device and export settings.
Public links open without a Flat account. Several files open in the explorer, where readers can choose a file. Original downloads remain available.
The exact path /motion.3g2 serves the original file. Opening that URL does not convert its container or codecs.
How to upload 3G2 files and get a link
Prepare your files
Copy the full recording from the source device. Keep the original file and check both picture and sound in a compatible player before handing it off.
If modern browser viewing is required, make a separate export with your own conversion tool. A new file extension alone does not update the 3G2 container.
Publish from your browser or terminal
In your browserGo to uploaderDrop, publish, copy the link.
Select your finished files in the uploader above. Enter your email if signed out, then choose "Publish videos".
Selected files need unique names and publish at the top level. The browser uploader does not accept folders or extract ZIPs. Use the CLI when relative paths matter.
TerminalNode.js 20+One command. Files or folders.
npx -y @getflat/cli deploy ./motion.3g2Replace the example path with your file, or pass a folder path to preserve its structure. The CLI prints the published URL.
Check the published result
Download the published 3G2 and check playback in the intended application. Keep a copy of the original outside the hosting workflow.
Signed-out uploads expire after 1 hour by default. Sign in before expiry to keep them online, or sign in before publishing for no default expiry.
When to use 3G2 hosting
Mobile recording handoffs
Share an original clip recovered from an older device with someone who can play or process 3GPP2 files.
Original and converted pairs
Publish the 3G2 beside a separately made viewing copy. Recipients can watch the copy and retain the original export.
Keep a version, or keep an address.
Share this version
Every upload gets its own link. Publishing revised files creates a new link and leaves the earlier version unchanged. Use the version link when someone needs to review a specific upload.
Update files at one address
Use a named onflat.page address or your own domain. Sign in, then publish with the CLI using --domain. Publish revised files with the same domain to point that address to the new upload.
Named addresses are included on Free. Adding your own domain requires a paid plan. The browser uploader does not set up or repoint these addresses.
3G2 hosting questions
Is hosting free, and what are the limits?
Yes. Signed-in Free includes 5 MiB per upload, 1 GiB of storage, and 5 GiB of monthly transfer, with no default expiry. The per-upload limit covers all files in that upload. Paid plans raise these limits.
Do readers need a Flat account?
No. Public links open without a Flat account. Anyone with the link can open the uploaded files. Password-protected links also require the visitor password.
Can I password-protect my upload?
Yes. Password protection is available on every plan. Add --password YOUR_PASSWORD to your CLI deploy command. It protects access to the upload and its files, but does not prevent someone with access from saving a copy. The browser uploader creates public uploads.
Can I replace files without changing the link?
A version link always refers to its original upload. For same-address updates, use a named address or your own domain. Publish revised files with the same --domain value in the CLI to point that address to the new upload.
What happens when an upload expires?
Flat stops serving it. An expired upload cannot be recovered. Signed-out uploads expire after 1 hour by default. For browser uploads, use the sign-in link shown after publishing. For CLI uploads, run npx -y @getflat/cli login. Complete sign-in before expiry to keep the upload online. If you chose a shorter expiry in the CLI, that deadline stays in place.
Can Flat repair or upgrade an old 3G2 recording?
No. Flat delivers the uploaded file unchanged. Repair, conversion, and codec selection belong in your video tools.
Can I use the 3GP guide for a 3G2 file?
The upload mechanics are the same, but the container specifications and possible codecs differ. Keep the correct extension and check the actual file.
How large can a video upload be?
Upload allowances depend on your plan and cover all files in the upload. Compare current plan limits. A larger upload allowance does not add codecs, container support, or transcoding. Original files remain downloadable when a preview is unavailable.
Can I embed this file on my website?
You can link to the original download. An HTML video element does not add a decoder for this container. Export a browser-compatible viewing copy with your own tool if you need embedded playback. Flat does not convert the original.
