Screen Recorder is a command-line capture tool for Windows that takes screenshots at a chosen frame rate, holds recent frames in memory, and writes them to disk on demand for performance investigations.
Screen Recorder is a Windows capture utility built for evidence gathering rather than polished video output. Instead of exporting a finished movie, it takes screenshots at a defined frame rate and keeps them in a circular in-memory buffer, so you can run a scenario and decide afterwards whether the captured frames are worth saving. Recording is controlled entirely from the command line: start capture with your preferred frame rate and monitor, exercise the behavior you want to observe, then stop and point the tool at a folder where the buffered screenshots should be written. Its purpose is to pair visible screen state with telemetry collected during the same session, which makes it most useful in performance and reliability troubleshooting.
Because Screen Recorder stays out of the way, it fits workflows where a graphical recorder would interfere with the measurement itself. You can leave capture running with a small buffer while reproducing a slow launch, a rendering glitch, or a corrupted interface state, then save only the frames that overlap the problem. The same command-line approach appeals to engineers who already automate their environment with scripts and console-driven clients, such as WebLogic Remote Console, rather than clicking through desktop applications. Frames land on disk with predictable filenames, so they can be reviewed alongside logs, traces, and other evidence gathered from the same machine at the same time.
Screen Recorder's biggest advantage is overhead discipline. Frames are held in memory instead of streamed to a file, so a long reproduction session does not fill your disk or compete with the workload you are trying to measure. You choose the frame rate and buffer size up front, which lets you trade memory for temporal resolution depending on how briefly the fault appears. Monitor selection matters too: target a single display when the issue is local, or capture every monitor when the failure spans a multi-screen setup. Stopping the tool writes the buffered frames to a folder you name, and cancelling discards them entirely, so failed reproductions cost nothing. Finally, because each received frame raises an event, captured images can be aligned with system traces collected at the same moment, turning a vague report that something looked wrong into a timestamped record.
Key capabilities and highlights.
Screen Recorder exposes a compact set of switches for starting, stopping, cancelling, and describing a capture session, so recordings can be driven from scripts, scheduled jobs, or deployment tooling rather than requiring a graphical interface, an open window, and a person sitting at the keyboard to press buttons.
The framerate switch sets how many screenshots per second the tool should capture, giving you direct control over the trade-off between detail and resource use. Lower values keep memory and disk consumption modest across long sessions, while higher values capture finer detail when a fault flashes past too quickly to notice by eye.
The monitor switch accepts a display index, letting you isolate a capture to a single screen when the problem is local. Choosing the highest available index records every monitor together instead, which is useful when a rendering or layout fault only appears across a multi-display arrangement where windows straddle two panels.
Captured frames are held in a rolling buffer instead of being written to disk immediately. One switch sets the buffer depth in whole frames, and its megabyte variant sizes the same buffer by memory consumption, so you can decide how much recent screen history stays in RAM during a long run.
Stopping a recording asks for a destination folder and writes every frame currently held in the buffer into it. Nothing is committed to disk until that moment, which keeps an extended reproduction run from filling storage with images you may never need to review.
The cancel option ends a recording and discards the buffered frames instead of saving them. Reproductions that fail to trigger the fault therefore leave no clutter behind, so you can retry the same scenario repeatedly without accumulating leftover screenshots or spending time cleaning them up.
Every frame received from DirectX raises an event that carries the filename the frame would take if it were saved. Tracing that provider lets you line up individual screenshots with everything else being recorded on the machine during the same session.
Because frames are published as events, the tool fits neatly into existing performance workflows: capture a profile with WPR while a recording is active, then open the resulting trace in WPA and read the captured frames from the generic events table alongside your other telemetry.

Common questions about Screen Recorder.
It captures screenshots of the display at the frame rate you specify and, when you stop the recording, writes the buffered images into a folder you choose. The output is therefore a series of image files that document what the screen looked like, not a finished video file with playback controls.
No. Everything is driven from the command line through the start, stop, cancel, and help switches, and no window needs to be open or focused. That is why it suits scripts, scheduled tasks, automation, and remote sessions where nobody is watching the screen while the capture runs.
Yes. The monitor switch takes a display index, and selecting a specific index restricts the capture to that one screen. Choosing the highest available index records all monitors together instead, which is helpful when a problem only shows up when windows span two or more displays.
Not always. Frames arrive from DirectX only when the screen changes, so a static desktop or an idle window produces fewer images than the requested rate. Treat the frame rate as a maximum target rather than a guarantee, and expect captured counts to rise during heavy on-screen activity.
Frames keep cycling through the in-memory buffer and are never written on their own. The recording only reaches disk when you stop it and name a destination folder, and it is simply dropped when you cancel instead, so nothing is saved accidentally.
It raises an event for every frame it receives, and each event includes the filename that frame would take if saved. Add that provider to a WPR profile, record your scenario, then open the trace in WPA to match each event with its screenshot.
No. Its documented behavior covers screen frames and their timing, and audio, microphone, and webcam inputs are not part of the recording pipeline it provides. If you need narration, camera overlays, or a playable video, a different class of recording application is required.
The documented switches target monitors rather than individual windows, so window-level capture is not a selectable option. Record the display the window sits on and crop the resulting frames afterwards if you need a tighter view for a report or bug write-up.
