Convert Mouse Recorder Pro Scripts Fast: Step-by-Step Guide
What this guide covers
A concise, practical walkthrough to convert Mouse Recorder Pro (.mrec) scripts into usable formats (e.g., plain text, AutoHotkey, Python with pyautogui) quickly and reliably.
Assumed defaults
- Source file: Mouse Recorder Pro 2 (.mrec) macro.
- Target examples: plain timestamped event log, AutoHotkey script, Python (pyautogui).
- OS: Windows.
- No GUI-only/manual re-recording.
Step 1 — Inspect the .mrec file
- Open the .mrec in a text editor (it’s XML-like or plain text depending on version).
- Note event types (mouse move, click, keypress), timestamps/delays, and coordinates.
Step 2 — Normalize timing
- Convert absolute timestamps to relative delays between events:
- For each event, compute delay = event_time(current) − event_time(previous).
- Round delays to milliseconds or desired granularity.
Step 3 — Map events to target language primitives
- Plain log: format each line as “DELAY(ms) EVENTTYPE parameters”.
- AutoHotkey:
- Mouse move: MouseMove, x, y
- Click: Click, left/right, x, y
- Keypress: Send or SendInput
- Delay: Sleep, milliseconds
- Python (pyautogui):
- Move: pyautogui.moveTo(x, y)
- Click: pyautogui.click(x, y, button=‘left’)
- Keypress: pyautogui.press(‘a’) or pyautogui.hotkey(…)
- Delay: time.sleep(seconds)
Step 4 — Write the converter (minimal algorithm)
- Parse .mrec into a list of events with timestamps and parameters.
- Compute relative delays.
- For each event, emit corresponding target-language lines, inserting delay instructions before the event when delay > 0.
- Wrap with initialization/cleanup (imports, sleep small startup delay, fail-safes like pyautogui.FAILSAFE = True).
Example pseudocode flow:
Code
read events from mrec prev_time = events[0].time for event in events:delay = event.time - prev_time if delay > 0: emit_delay(delay) emit_mapped_event(event) prevtime = event.time
Step 5 — Handle edge cases
- Relative vs absolute coordinates: detect if coordinates are screen-based; provide option to convert to window-relative.
- Modifier keys (Shift/Ctrl/Alt): emit proper press/release sequences.
- High-frequency events: throttle or merge near-duplicate moves to avoid performance issues.
- Non-supported events: log them and skip or substitute best-effort equivalents.
Step 6 — Test and validate
- Run converted script in a controlled environment (virtual machine or isolated window).
- Compare key checkpoints: cursor path, clicks, typed text, timing behavior.
- Adjust delays or coordinate scaling as needed.
Quick conversion examples
- AutoHotkey snippet:
Code
Sleep, 500 MouseMove, 400, 300 Sleep, 50 Click, left, 400, 300 Sleep, 200 Send, Hello
- Python (pyautogui) snippet:
python
import time, pyautogui time.sleep(0.5) pyautogui.moveTo(400, 300) time.sleep(0.05) pyautogui.click(400, 300) time.sleep(0.2) pyautogui.write(‘Hello’)
Tools and libraries
- XML/JSON parsers (depending on .mrec format)
- pyautogui (Python)
- AutoHotkey (Windows)
- Optional: build a small GUI with Electron or Tkinter for drag-and-drop conversion
Safety and reliability tips
- Add an initial countdown (3–5 seconds) before running to allow focus switching.
- Include a hotkey or fail-safe to abort (e.g., move mouse to a corner for pyautogui).
- Log actions during test runs for troubleshooting.
Quick checklist before using converted script
- Coordinates correct for target display/resolution
- Timing preserved or adjusted intentionally
- Modifier keys handled
- Fail-safe present
- Tested in a safe environment
If you want, I can produce a ready converter script in Python that reads .mrec and outputs AutoHotkey or pyautogui code—specify target and whether coordinates should be screen- or window-relative.
