Open a project stuffed with 4K, 6K, or RAW footage and even a powerful machine starts to chug — dropped frames, laggy scrubbing, a timeline that stutters every time you move the playhead. Proxies are the fix. A proxy is a smaller, lighter copy of your original media that Premiere Pro edits in place of the heavy file, then swaps the full-resolution original back in automatically at export. Smooth playback while you work, full quality when you deliver.
Why create proxies in the first place?
It comes down to one thing: playback performance. Premiere has no trouble with a short 1080p timeline, but the moment you stack up heavy codecs and long sequences it starts to choke — and it does not matter how expensive your computer is. There is always footage heavy enough to bring it to its knees.
The classic cases are the big jobs: a feature film with thousands of clips, a multi-day commercial shoot full of RED and drone footage, a documentary with twenty hours of interviews. None of that plays back smoothly at full resolution on any machine. Proxies let you cut the whole thing as if it were lightweight 1080p, so your creative flow never gets interrupted by a spinning beachball. They are just as useful editing 4K on an older laptop, or roughing out a cut on the road before you get back to your main rig. Anywhere playback is the bottleneck, proxies remove it.
What a proxy actually is
A proxy is a duplicate of your clip at a lighter codec and a smaller frame size. The key thing to understand is that it is non-destructive: every cut, trim, effect, and keyframe you apply lives on the real footage underneath. The proxy is only a stand-in for playback. Switch back to full resolution and your timeline is identical — nothing about your edit changes. That is what makes proxies safe to lean on as hard as you want.
How to create and use proxies
Select your footage
In the Project panel, select the clips you want to proxy — Ctrl+A grabs everything in the bin.
Open Create Proxies
Right-click the selection and choose Proxy > Create Proxies.
Pick a format and destination
ProRes Proxy is a safe default; H.264 makes the smallest files. Point the destination at a dedicated Proxies folder to keep things tidy.
Let Media Encoder render
Click OK and Premiere hands the job to Adobe Media Encoder, which renders every proxy in the background while you keep working.
Add the Toggle Proxies button
In the Program Monitor, click the + (Button Editor), drag in Toggle Proxies, and click OK — now one click swaps the whole project between proxy and full-res.
Choosing a proxy format
If you are not sure, ProRes Proxy is the one to pick. It looks good enough to judge focus and framing, stays small, and plays back smoothly on almost anything.
When to toggle proxies
Edit with proxies on whenever playback stutters or scrubbing lags. Toggle them off for final color grading and export, or any time you need to judge true full-resolution quality — a blue highlight on the button means proxies are active. The habit that saves you: always confirm the toggle is off before you hit export.
When you need proxies — and when you don't
Reach for proxies when playback is struggling: 4K and up, heavy codecs (RED, ProRes RAW, H.265, some mirrorless H.264), long multi-scene timelines, or an underpowered machine. Skip them when you don't need them — a two-minute 1080p edit, or a short project that already scrubs smoothly, gains nothing from the extra render time and disk space. Proxies are a performance tool, not a default step for every project.
Common proxy mistakes (and how to fix them)
- Your export looks soft. You almost certainly exported with proxies still on. Toggle proxies off before exporting and confirm the button is dark.
- Proxies aren't generating. They render in Adobe Media Encoder — make sure it is installed and its queue is actually running. A paused queue does nothing.
- "Media offline" after moving files. Proxies are linked to a location. If you move the project or drives, right-click the clips and use Proxy > Reconnect Full Resolution Media to relink.
- You want to remove them. Right-click and choose Proxy > Attach Proxies or detach to add or drop proxies from clips without ever touching your edit.
Pro tip: Create proxies right after import, before you start cutting. Turn on Ingest settings in the Project panel so new footage is proxied automatically the moment you bring it in — by the time you are ready to edit, they are already done.
Where proxies fit in your workflow
Proxies are the engine of the offline stage — the creative cut, made on light files — before you conform to full resolution for finishing and color. If that pipeline is new to you, our guide to offline vs online editing walks through it end to end, and the media-management guide covers keeping footage organized so the full-res conform never goes offline. For more timeline fundamentals, see the Premiere Pro timeline panel explained.
Edit on light copies; Premiere swaps in the originals at export.
Heavy codecs and long timelines choke any machine — proxies fix it.
Select clips → right-click → Proxy → Create Proxies → pick a preset.
A soft export almost always means proxies were left on.
Ingest settings auto-generate proxies as you bring footage in.
Speed up the rest of your cut with Filmit
Proxies keep playback fast; Filmit's editor tools keep the cut itself fast — JumpCut strips silence and dead air automatically, Sourcer drops stock onto the timeline, and Comper builds sequences from your selects. All inside Premiere Pro.
