ReplayCapture
Instant-replay buffer for Windows: keeps the last 45–60 seconds of every display in memory continuously and dumps it to disk on Alt+F10 — one file per display, each with as many separate audio stems as you want.
Comparison
| ReplayCapture | OBS | ShadowPlay | AMD ReLive | |
|---|---|---|---|---|
| Multi-display | Every display, one .mov per display — no manual scene/canvas setup |
Multi-display possible, but composited onto a single canvas you build yourself | Primary display only | Primary display only |
| Per-process audio | Rule grammar per track: proc:discord.exe, proc:!discord.exe, proc:*, group:comms, group:!music — named groups, wildcards, unlimited tracks |
Per-source process capture, but routing multiple processes into separate output tracks needs manual filter/mixer setup | Not supported | Not supported |
| Audio track count | Arbitrary — add an entry to config, muxer writes another track | Limited by output format / manual mixer tracks | Fixed, game + mic only | Fixed, game + mic only |
| Container | .mov with N discrete audio tracks — the only format Premiere imports natively with all tracks intact (no MKV support, unreliable multi-track MP4) |
MP4/MKV/FLV, single mixed-down or manually-tracked audio | MP4, no multi-track | MP4, no multi-track |
| Encoder | NVENC / AMD AMF / x264 software, switchable per display | Wide encoder choice, manual setup | NVENC only | AMF only |
| Footprint | Tray-only, no window, always-on background buffer | Full app with scenes/sources UI, meant to be actively run | Bundled into GeForce Experience | Bundled into AMD Software: Adrenalin Edition |
| Reliability under focus-stealing | Runs elevated specifically so Alt+F10 survives admin windows/anti-cheat holding focus | Hotkeys can drop under UIPI like any medium-integrity app | NVIDIA-signed, elevated by driver | AMD-signed, elevated by driver |
Built because none of OBS, ShadowPlay, or ReLive cover "record every monitor separately, with per-app audio isolation, in a format Premiere actually opens" — everything else here is scaffolding for that one requirement.
