Finding the file Microsoft filed for you
Teams recordings stopped living in Stream Classic and moved into the storage you already had. Where exactly depends on the meeting: a regular scheduled or ad hoc meeting saves into the recorder's OneDrive, in a folder called Recordings, while a channel meeting saves into that channel's SharePoint document library, also under Recordings. The meeting chat gets a link, not a file, which is why the link is what everyone forwards and why nobody can find the mp4 later.
Open the link, then use Download to get the actual .mp4 onto your disk. If your tenant has downloads locked off, stop there. That restriction exists because someone decided this footage should not leave the tenant, and routing around your own IT department is a worse idea than not having the GIF.
There is a clock on it, and you did not set it
Microsoft ships an automatic expiration on new Teams meeting recordings. The default is measured in weeks rather than years (60 days at the time of writing), administrators can raise it, lower it, or switch it off, and any retention policy your organization layers on top applies as well. When the clock runs out the recording goes to the recycle bin on its own schedule, with no ceremony.
That is a perfectly reasonable storage policy and a terrible archive. If a demo, a decision, or a number said out loud is worth referring back to in six months, the durable version is not the recording. It is a few seconds of it, converted to something small enough to live inside the ticket, the doc, or the release notes where the question will actually come up.
The second copy is the part to be careful about
Meeting footage inside a corporate tenant sits within a governed boundary: retention rules apply to it, legal holds can reach it, access is logged, and its lifetime is on record. Push that same file to an upload-based converter and you have created a copy outside all of it, sitting on infrastructure your organization has no relationship with, for a duration nobody in your company can state. The meeting was never the exposure. The copy is.
Converting locally produces no second copy at all. The .mp4 is read by the page, decoded by your browser, and re-encoded into a GIF by your own processor, and the only new artifact in existence is the file you chose to save. If you want the mechanics of that spelled out before you drop anything in, the private converter page is the long form.
You cannot un-composite a meeting, so crop
Teams records what the layout looked like while it was recording. Gallery tiles, the speaker's spotlight, the shared screen and the strip of faces beside it: all of it is flattened into one video track. There is no going back and choosing a different view later, which makes the crop your only editorial control over who and what appears in the loop.
In practice that means deciding what the clip is about before you touch a setting. If it is about the slide, crop to the shared-screen region and the faces are gone. If it is about the reaction, crop to the tile. The ratios lock to exact shapes (1:1, 9:16, 4:5, 4:3, 16:9), so a square cut of one tile comes out square rather than subtly stretched, and cutting the frame down is also the cheapest file-size win available before you have changed a single dial.
A recipe for slides, faces, and one honest limit
Meeting video is slow, flat footage, which makes it unusually kind to a GIF. Trim to two to five seconds, then set the frame rate at 10 to 12 fps, the width somewhere between 480 and 640, and the palette between 96 and 128 colors, nudging upward if a shared spreadsheet's small type starts to smear. Turn dithering on when a photo or a gradient in the deck begins to band. Since a GIF is silent, the quote that made the moment can ride along as text: up to three captions, placed anywhere on the frame, each with an optional time window so a line appears only for the beats it belongs to.
The limit, stated plainly: this tool does not join your call and does not record it. Teams does that part, and it should. It also cannot reach into SharePoint on your behalf, so the file has to come from you, either as a download or, on a desktop browser, by using Record a Tab to capture the replay as it plays. From there it is an ordinary MP4 to GIF job. Open the converter when you have the file.
