Frequently asked questions
- Will changing the frame rate change the playback speed?
- No — this changes how many frames per second are stored, not the video's duration. A 10-second clip stays 10 seconds whether it's 24fps or 60fps; frames are added or dropped to hit the new rate, and playback speed is unaffected.
- Why would I lower the frame rate?
- A lower frame rate (like 15fps) produces a smaller file, which is useful for quick previews, GIF-style clips, or uploads with strict size limits. Higher rates (60fps) look smoother for motion-heavy footage like sports or gaming.
- What video formats can I use?
- Any format your browser can decode — MP4, WebM, MOV, and MKV all work in most current browsers. Export as MP4, WebM, MOV, or MKV.
- Is my video uploaded anywhere?
- No — the conversion happens entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — converted in this tab | Yes, uploaded to process |
| Duration stays exactly the same | Yes | Varies — some tools drift on frame rate changes |
| Account required | Never | Often, past a certain usage level |
