Learn MoreThe best free screen recorder for Roblox in 2026 is OBS Studio — zero cost, no watermark, no FPS cap, and works for both recording and live streaming. For players who want automatic clip detection, Medal.tv (free, local) and Eklipse (free, cloud-based for streamers) add AI that identifies your best moments without reviewing hours of footage.
This guide covers every option — from the simplest one-click recorders to full streaming + auto-clip setups — so you can pick the right tool for how you actually play.
TL;DR
- Best free recorder (no restrictions): OBS Studio — no watermark, any resolution, no clip length limit
- Best for simplicity: Medal.tv — install, play, it clips automatically
- Best for streamers wanting auto-clips: Eklipse — processes your Twitch/Kick Roblox VOD into 9:16 clips post-stream
- Built-in option (Windows): Xbox Game Bar (Win+G) — instant replay, no install, lower quality
- Avoid: Free screen recorders with 10-minute limits or mandatory watermarks
1. OBS Studio — best overall free recorder
Free. No watermark. No time limit. No catch.
OBS Studio is the most capable free screen recorder available. It captures Roblox at any resolution and frame rate with zero mandatory watermark, supports both local recording and live streaming, and runs on Windows, macOS, and Linux.
Setup for Roblox recording:
- Download from obsproject.com
- Add a Game Capture source, select Roblox
- Set output: 1920×1080, 60fps, NVENC H.264 (NVIDIA) or AMF (AMD)
- Press Start Recording
Why Game Capture over Display Capture: Game Capture hooks directly into the Roblox process — lower CPU overhead, no lag from capturing a secondary monitor, and Roblox renders in full quality.
Recommended recording settings:
| Setting | Value |
|---|---|
| Encoder | NVENC H.264 (NVIDIA) or x264 (CPU) |
| Rate control | CRF (recording) — use CRF 18–23 |
| Resolution | 1920×1080 |
| FPS | 60 |
| Format | MP4 (easier to edit) or MKV (safer if OBS crashes) |
Trade-off: OBS has no automatic clip detection. You record everything and manually find the good moments afterward — or you use the replay buffer (records the last N seconds on hotkey) to save specific moments as you play.
Best for: Roblox players who want full control, no restrictions, and plan to edit clips manually or use a separate tool for highlight detection.
2. Medal.tv — best for automatic clip detection (offline players)
Free tier available. Runs locally. AI detects highlights automatically.
Medal.tv runs as a background process during your Roblox session. It captures everything and uses AI detection to identify notable moments — kills, deaths, certain score events — and saves short clips automatically.
How it works:
- Install Medal from medal.tv
- Launch Roblox — Medal starts capturing automatically
- After your session, open Medal and review detected clips
- Download and share from the Medal interface
For Roblox specifically:
- Works well for PvP games (Arsenal, Combat Warriors, Da Hood) — kill events are detected reliably
- Limited for progression games (Blox Fruits, Pet Simulator) — “fruit awakening” isn’t a standard kill event
- Captures funny moments only if they trigger an audio spike — not as sophisticated as chat-based detection
Performance impact: 8–12% CPU during recording. On a modern Ryzen 5 or Core i5 PC, this is barely noticeable. On older or lower-spec machines, you may see frame drops in busy Roblox maps.
Free plan limitations: 720p capture, Medal watermark on exports. Medal Pro removes the watermark and unlocks higher resolutions.
Best for: Roblox players who don’t stream live and want automated clip detection without any streaming setup.
3. Eklipse — best for Roblox streamers
Free tier available. Cloud-based. Zero FPS impact. Processes Twitch/Kick VODs automatically.
Eklipse is not a traditional screen recorder — it processes your Twitch or Kick VOD after your stream ends. Connect your Twitch account, stream Roblox as normal, and Eklipse finds your best moments and exports them in 9:16 vertical format for TikTok and YouTube Shorts.
How it works:
- Create an account at app.eklipse.gg
- Connect Twitch or Kick via OAuth
- Stream Roblox — no changes to your setup
- After the stream, Eklipse processes the VOD automatically
- In 20–60 minutes, detected clips appear in your dashboard ready to download
What makes it different for Roblox:
- Chat spike detection: When 300+ chat messages appear in 5 seconds, something notable happened. Eklipse catches this — a funny moment, an unexpected clutch, a dramatic event — even if it didn’t generate a kill-feed event
- Zero performance overhead: Runs entirely in the cloud after your stream ends. Your Roblox session is unaffected
- 9:16 output by default: No reformatting for TikTok or Shorts — clips are already the right aspect ratio
Best for: Roblox streamers on Twitch or Kick who want automatic highlights from their VODs without reviewing footage manually.
Requires: Active Twitch or Kick account with VOD storage enabled.
4. Xbox Game Bar — built-in Windows option
Free. Built into Windows 10/11. Zero install required.
Press Win+G while Roblox is running to access Xbox Game Bar. It includes:
- Screen recording (record your session)
- Instant replay (saves last 30–120 seconds via Win+Alt+G hotkey)
- Screenshot (Win+Alt+PrtScn)
Pros: Already on your PC, zero setup, hotkey accessible during gameplay.
Cons: Lower quality than OBS, no AI detection, 16:9 only, limited bitrate control, doesn’t work in all Roblox modes.
Best for: Casual Roblox players who need to clip something once and don’t want to install software.
5. NVIDIA ShadowPlay / GeForce Experience
Free with NVIDIA GPU. Hardware-accelerated. Minimal performance impact.
If you have an NVIDIA GPU (GTX 1060 or newer), ShadowPlay is worth using:
- NVENC hardware encoding — CPU overhead is near-zero (2–4%)
- Instant Replay: saves the last 5–30 minutes on hotkey (Alt+F10)
- Auto-saves highlights for some games (not Roblox-specific)
- No time limit, no watermark
Setup: Install GeForce Experience, enable In-Game Overlay, configure Instant Replay duration.
For Roblox: Manual trigger — you press the hotkey when you want to save a clip. No automatic detection.
Best for: NVIDIA GPU owners who want high-quality, zero-overhead instant replay without any subscription or AI detection.
6. AMD ReLive / Radeon Software
Free with AMD GPU. Similar to ShadowPlay for AMD hardware.
AMD ReLive captures via hardware encoding on AMD GPUs with minimal overhead. Instant replay, manual trigger, no watermark, no time limit.
Best for: AMD GPU owners who want the ShadowPlay equivalent for free.

What to consider when choosing
Do you stream Roblox on Twitch or Kick? → Eklipse. Zero overhead, post-stream automation, 9:16 output. Add OBS for the actual streaming.
Do you play Roblox without streaming? → Medal.tv if you want AI detection, OBS or ShadowPlay if you prefer manual clipping with higher quality.
Do you have an NVIDIA GPU? → ShadowPlay for instant replay hotkey recordings, OBS for full sessions.
Do you just need to clip something occasionally? → Xbox Game Bar. Already installed, no setup.
Do you want to post Roblox clips to TikTok and YouTube Shorts? → Either Eklipse (if you stream) or record with OBS then reformat in CapCut.
Frequently asked questions
Does recording Roblox use more CPU?
Yes, but hardware-accelerated recording (NVENC, AMF, ShadowPlay) has very low overhead — 2–5% CPU. Software encoding (x264 in OBS) uses more CPU — 20–40% depending on quality settings. Use hardware encoding for Roblox to minimize FPS impact.
Can I record Roblox gameplay on a laptop?
Yes. OBS runs on laptops. Use hardware encoding (NVENC if NVIDIA, AMF if AMD Radeon, QuickSync if Intel) to keep CPU overhead low on laptop thermals. Lower the bitrate (4,500 kbps instead of 6,000) to reduce heat buildup.
Will screen recording cause Roblox to ban me?
No. Recording your own gameplay is permitted. Roblox doesn’t ban players for using screen recorders.
How do I record Roblox clips on a school or work PC?
If you can’t install software, use Xbox Game Bar (Win+G) — it’s already on Windows 10/11 and doesn’t require admin permissions in most configurations.
