Flashback gives you precise control over how your gameplay footage is captured. Every option you configure — resolution, frame rate, quality preset, microphone — applies equally to both manual recordings and the instant replay buffer, so you never need to tune them separately.

localStorage and take effect immediately the next time a recording or replay session starts.
Opening Capture Settings
Navigate to Settings → Captura from the Flashback sidebar. All capture options are grouped in that panel.Resolution
The resolution setting controls the output height of the recorded video. Flashback always captures at your monitor’s native resolution using Windows Graphics Capture (WGC) and then downscales to the target height during encoding — it never upscales. If your monitor runs at 1080p and you choose 1440p, the output will be capped at 1080p.| Option | Output height | Notes |
|---|---|---|
| 480p | 480 px | Smallest files; suited for very long recordings |
| 720p | 720 px | Good balance for streaming or sharing |
| 1080p | 1080 px | Default — full HD, recommended for most setups |
| 1440p | 1440 px | Requires a 1440p or 4K monitor to take effect |
| 2160p | 2160 px | Maximum quality; very large files |
Aspect ratio is always preserved during downscaling. For a 16:9 1080p monitor, choosing 720p produces a 1280×720 video.
Frame Rate
Frame rate (FPS) controls how many video frames are recorded each second. Higher FPS captures smoother motion but increases file size proportionally, since bitrate scales with FPS in Flashback’s encoding formula.| Option | Use case |
|---|---|
| 20 fps | Long background recording where motion fidelity is less important |
| 30 fps | Standard cinematic feel; noticeably smaller files than 60 fps |
| 60 fps | Default — smooth gameplay, ideal for most titles |
| 120 fps | High-refresh-rate gaming; doubles the file size versus 60 fps |
| 240 fps | Maximum; for competitive shooters or slow-motion analysis |
Quality Presets
Quality controls the bits-per-pixel-per-frame factor used to compute the video bitrate. The actual bitrate formula is:| Label (UI) | Quality key | Factor | Approx. bitrate @ 1080p60 |
|---|---|---|---|
| Bajo | low | 0.15 | ~19 Mbps |
| Medio | normal | 0.27 | ~34 Mbps |
| Alto | high | 0.40 | ~50 Mbps — Default |
| Muy alta | veryhigh | 0.72 | ~90 Mbps |
| Ultra | ultra | 1.05 | ~130 Mbps |
Bitrate scales automatically with your resolution and FPS choices. Selecting Muy alta at 720p30 uses far less space than Muy alta at 1080p60.
Microphone
Flashback can mix a microphone track directly into the clip. This is useful for commentary, voice chat, or any audio you want permanently embedded alongside the game footage.- Mic toggle — enables or disables microphone capture entirely.
- Device selection — when enabled, a dropdown lists all audio input devices detected by the system (populated via
list_audio_inputs()). Choose the device you want to record. The selected device ID is persisted inlocalStorageunder the keyflashback.capture.micDevice.
Microphone audio is mixed into the clip at capture time. There is no separate mic track in the exported file.
Replay Buffer
The replay buffer runs continuously in the background, keeping the last N seconds of gameplay ready to save on demand.- Enable toggle — turns the background replay buffer on or off.
- Buffer duration — how many seconds of footage are retained. Options: 30 s, 1 min, 2 min, 3 min, 5 min, 10 min, 15 min. Default is 1 minute.
Alt+F8), Flashback flushes the buffer to a clip file. See Instant Replay for the full workflow.
