FrameBurst v1.0.0

FrameBurst v1.0.0

The first release of FrameBurst: a system tray screenshot tool for Windows that captures the highest-quality
image possible, with every step done on the GPU through Direct3D 11 (NVIDIA, AMD and Intel).

Download

FrameBurst-Setup-1.0.0.exe:
run it and follow the steps.

• No admin rights needed. It installs for your user account by default, or for all users if you choose.
• .NET is included, so nothing else needs to be installed.
• Optional: start with Windows (on by default) and a desktop shortcut.
• Uninstall any time from Settings › Apps › Installed apps.

Requirements: Windows 10 version 2004 or later, or Windows 11 (64-bit), and a Direct3D 11 GPU.

Highlights

Pixel-exact, GPU-accelerated capture

• Each monitor's frame is taken straight from the Windows compositor with Windows Graphics Capture as a
  Direct3D 11 texture, with no GDI copies.
• All monitors are captured at the same moment, each on the GPU that drives it, including hybrid laptops
  with integrated and dedicated graphics.
• A D3D11 compute shader converts every frame to 8-bit sRGB exactly, whether Windows composites in 8-bit
  or FP16 (Auto Color Management). All 16,777,216 colours are verified to come out unchanged.
• About 45 ms from hotkey to pixels in memory for three monitors (9.9 MP). The shader itself runs in about
  0.5 ms.

Capture modes

Input	Captures
PrintScreen	A region (drag, or click a window)
Ctrl+PrintScreen	All monitors
Shift+PrintScreen	The monitor under the cursor
Alt+PrintScreen	The active window
Click the tray icon	A region, after a 1-second delay

• Every hotkey can be changed in Settings.
• Hotkeys work over full-screen games and apps. A low-level keyboard hook catches the key before the game
  does, so the capture still starts, and the game doesn't receive the key press.

Region overlay

• Freezes the screen across every monitor.
• Drag to select, or click a window to take it.
• Enter takes the monitor under the cursor, F takes the whole desktop.
• Arrow keys move the cursor 1 px for precise edges.
• A magnifier shows the surrounding pixels, the screen coordinates and the colour under the cursor.

Built-in editor

Draw on the frozen screen before choosing what to capture:

• Pen, Highlighter, Arrow, Rectangle, Text and Blur, each with a one-key shortcut
  (P, H, A, R, T, B).
• Colour palette, adjustable line width, text size and blur strength (mouse wheel or [ ]).
• Undo and redo (Ctrl+Z / Ctrl+Y).
• Edits change only the pixels they cover; everything else stays pixel-perfect.

Screen colour picker

• Freezes the screen with a magnifier and live hex/RGB readout.
• Click to copy the exact colour as #RRGGBB.

Output

• Lossless PNG from a custom multi-threaded encoder, with three compression levels (speed vs file size).
• Saved to Pictures\FrameBurst with a customisable file name pattern using .NET date codes. A Read more.
  link in Settings lists every code.
• Copied to the clipboard as an image, a PNG and a file, so it pastes into chat apps, image editors and File
  Explorer.
• A notification after each capture. Click it to show the file in File Explorer.
• Optional capture delay and mouse cursor capture.

Automatic updates

• FrameBurst checks this repository for new releases once a day and asks before installing anything.
• Updates are verified against GitHub's SHA-256 checksum, then installed silently. FrameBurst restarts on its own.
• Check any time from the tray menu (Check for updates…), or turn automatic checks off in Settings › Updates.

Known limitations

• HDR isn't supported. On a monitor in Windows HDR mode, captures are clipped to SDR. Turn HDR off for that
  monitor before capturing it.
• DRM-protected video shows up black. Windows enforces this.
• On Windows 10 a yellow capture border may flash briefly around the screen. Windows 11 hides it.
• The secure desktop (UAC prompts, the lock screen) cannot be captured.
• Games running as administrator, or protected by some anti-cheat software, may block the hotkeys.
• Inverting cursors (such as the I-beam) are approximated when cursor capture is on.
