A few weeks ago, we were on a call with a streaming company that runs a mix of sports events, interviews, and community shows using vMix. Their setup was solid. Their production team knew their workflow inside out. But the moment we asked how they handled live clipping, everyone on the call laughed the same tired laugh.
Their production lead put it perfectly:
“We always see the moment happen live… but we never get it out fast enough.”
He walked us through a typical day. A highlight would happen mid-stream, a reaction, a goal, a moment that would perform well on social and suddenly the control room would shift into chaos. Editors scrambling. Someone calling out timestamps. Someone else trying to scrub a two-hour recording. Everyone hoping the export didn’t glitch.
They needed clipping to be instant and not 2 hours later and certainly not after scrubbing files.
And they weren’t alone most team we speak to hits the same wall. This is why the workflow we’re about to explain exists. vMix stays focused on production, exactly what it’s great at, while FastPix adds the ability to capture the moment the second it happens.
One of the biggest shifts in live streaming today is how quickly moments move. The audience doesn’t wait for recaps anymore. When something interesting happens on a live stream, people expect to see it as a short, a replay, or a highlight almost immediately, not after the broadcast ends.
This came up again and again when we spoke with teams across sports, creators, education, gaming, and events. Different formats, different workflows, and the same sentence every time:
“We saw it happen live, the chat exploded… and we still couldn’t get the clip out fast enough.”
And when your entire workflow depends on waiting for a recording, scrolling through huge files, or manually hunting timestamps, the moment simply loses its momentum. The window where that highlight matters shrinks down to minutes.
That’s why clipping during the live stream isn’t a “nice to have” anymore, it’s the only way to keep up with how your current audiences watch and interact with content.
When you connect your vMix output to FastPix using a simple RTMP or SRT endpoint, nothing about your production workflow changes, the switching, graphics, overlays, and audio all continue exactly as they do today. What changes is everything that happens after the moment.
FastPix becomes a live buffer running alongside your stream. As vMix sends frames out, FastPix holds them in a rolling timeline you can scrub at any point during the broadcast. That buffer gives you DVR-style rewind, real-time preview, and precise trimming controls without waiting for a recording to finish or loading a large file.
There’s no new hardware to set up, no new control-room steps, and no disruption to the team already running the show. It’s simply a cloud layer that sits behind your vMix feed and makes every moment accessible the instant it happens.
Everything begins inside vMix. You take the RTMP or SRT ingest URL from your FastPix dashboard, paste it into vMix as an external output, add your stream key, and go live as usual. Nothing changes in your control room, FastPix simply receives a real-time version of the same program feed you’re already broadcasting.
As soon as the stream reaches FastPix, a rolling DVR-style buffer begins in the background. It quietly stores the last several minutes of your live output, giving you room to scroll back without needing the full recording or waiting for the stream to end.
When something worth clipping happens, you open the FastPix dashboard and scrub through the live. The timeline provides immediate, frame-accurate previews so you can land exactly on the beginning of the moment, even if it happened a few minutes earlier. This replaces the painful “hunt through a long file” workflow most teams deal with.
Once you’re on the right part of the live, trimming is straightforward. You set your in and out points, check the preview, and FastPix handles the extraction instantly in the background.
When the clip is ready, you can download it directly or publish it to a storage bucket, share it with editors, or push it straight into your content pipeline. The entire sequence happens while your vMix show continues as normal, which means you’re never interrupting the stream to capture the moment.

Real-time clipping isn’t just a convenience feature, it solves a timing problem that shows up across almost every type of live production built on vMix. Here are four of the most common situations where being able to trim moments while the stream is still running makes a clear difference.
1. Sharing important moments during live events
Events of all kinds, product launches, conferences, workshops, town halls often have moments that need to be shared instantly. Whether it’s a key announcement, a standout demo, or a spontaneous moment on stage, real-time clipping allows teams to publish these highlights while the event is still happening, keeping momentum strong and conversation active.
2. Capturing highlights from sports, gaming, and competitive streams
Fast-paced formats rely heavily on timing. A great play, a match-winning moment, or an unexpected reaction loses impact if it takes fifteen minutes to extract. With a live buffer, teams can pull these segments immediately and post them before the game or session even ends.
3. Extracting key clips from interviews, discussions, or educational sessions
Live interviews, Q&As, classroom sessions, and panel discussions often contain moments that stand out, a great quote, a sharp insight, or a memorable explanation. Real-time clipping makes it easy to grab these segments the moment they happen, instead of waiting for long recordings to process.
4. Building recaps and short-form content before the stream finishes
Many teams produce quick recaps or follow-up content right after a stream ends. With instant clipping, the recap process happens in parallel with the live show, not after it. By the time the session wraps, the best moments are already trimmed, labeled, and ready to publish, reducing the need for rushed post-production.
Every creator we’ve talked to had the same experience: once they moved to real-time clipping, their entire workflow felt lighter. Moments that used to take ten minutes to extract suddenly took less than a minute. The stress around “who marked the timestamp?” disappeared. And the constant back-and-forth between the live team and the editors almost completely went away.
The biggest shift wasn’t just speed, it was momentum.
When you can pull a clip while the stream is still running, you don’t lose the energy of the moment. Social posts go out when viewers are still reacting. Highlights get shared before the stream ends. Recaps are built as the show progresses instead of after. And teams, even small ones, feel like they finally have breathing room instead of constantly racing the clock.
With real-time clipping, creators stop waiting for exports, stop digging through giant recordings, and stop interrupting their flow just to capture something they already saw happen live. The workflow simply becomes calmer, faster, and more predictable — and that makes the content better too.
Real-time clipping changes how live content feels to make, not just how fast it ships. Once you can rewind your stream, cut a moment cleanly, and reuse it while you’re still live, the entire workflow becomes easier, for you, for your editors, and for anyone who needs that highlight quickly.
If you’re already streaming with vMix, the simplest way to experience this is to try it on your next show. Connect your vMix feed to FastPix, let the DVR buffer start filling, and pull your first live clip straight from the dashboard. It takes a few minutes to set up, and the difference is obvious the moment something happens on air that you want to capture.
Whenever you’re ready, you can sign up and give the workflow a spin, and if you do try it, we’d genuinely love to hear what it changes for you.
Does FastPix support clipping from vMix using SRT instead of RTMP?
Yes. FastPix accepts both SRT and RTMP ingest, so you can continue using your existing vMix SRT workflow without changing anything.
Will using FastPix for clipping increase my live stream latency on vMix?
No. The clipping workflow runs on a separate ingest path, so your viewer-facing latency and production pipeline stay exactly the same.
What is the best bitrate and resolution to send from vMix to FastPix for clean clips?
Most creators use their standard streaming presets (often 1080p at 6–12 Mbps). FastPix ingests whatever you send, but higher bitrates produce cleaner highlights.
Does FastPix save my clipped videos automatically?
Yes. Every clip created from the live buffer is saved in your FastPix workspace, ready to download, review, or publish to your storage.
How long can I rewind a live vMix stream in FastPix?
The available rewind window depends on your workspace plan, but typically ranges from a few minutes up to a longer rolling buffer designed for capturing unexpected moments during live shows.
