Free Screencast 8.1.0
=====================

A free, local Windows screen recorder built by directly modifying ShareX 21.0.0.
This is an independent modified distribution, not an official ShareX release.
Windows 11 22H2 (build 22621) or later, x64, is required. The .NET desktop
runtime is included; no separate runtime installation is necessary.

Start FreeScreencast.exe. Record a region, display, or the current screen area
of a selected window. MP4 and animated GIF, pause/resume, screenshots, local
recordings, hotkeys, dark/light themes and ShareX advanced tools are included.
Window recording follows its current screen rectangle: keep that window visible,
uncovered, unmoved and not minimized. GIF has no audio. The simple audio selector
uses one available DirectShow device at a time. System sound requires an existing
compatible loopback/Stereo Mix/virtual capture device; no audio driver is installed.

The default theme is dark; the theme button switches to light and remembers your
choice. brand.ini beside the EXE controls the display name using [Brand] Name=.
Restart after editing. Invalid or missing branding falls back to Free Screencast.
An existing brand.ini is preserved by setup and uninstall.

This portable ZIP includes a Portable marker: user settings/history stay in the
FreeScreencast subfolder beside the EXE. Extract the full ZIP to a writable folder.
The separately distributed installer uses Documents\FreeScreencast instead.
Uninstalling this application leaves those user files and recordings intact.
The basic recording interface saves locally and needs no account. Advanced ShareX
upload tools are available only when you choose to use/configure those features.

RelevantKnowledge (RK) is separate optional research software by TMRG/Comscore.
This setup discloses the invitation; only the official visible Agree/Decline UI
decides participation. You can skip/decline; the recorder works without RK.
Silent main installation skips the RK download and launch entirely. If accepted,
RK must be managed/uninstalled separately in Windows Settings > Apps. See
Research-information.html for policy/help links and more information.

ShareX options requiring those features need a compatible user-supplied FFmpeg.
