How to Speed Up Video in MPC-HC Without Changing the Pitch

Media Player Classic - Home Cinema (MPC-HC) remains a favorite among power users for its lightweight design and robust feature set. One of its most practical features is the ability to speed through slow-paced content—whether it’s a long lecture, a tutorial, or a slow-burn drama—without making the speakers sound like chipmunks.

Unlike some modern players that simply fast-forward, MPC-HC uses smart audio processing to maintain the original pitch while increasing speed. Here is how to set it up and use it effectively. mpc hc speed up without pitch

7. Implementation Notes and Tips

• Use consistent sample rates between decoder, filter, and renderer to avoid resampling artifacts.
• Disable audio enhancements in Windows Sound control panel that could interfere.
• Monitor CPU and adjust buffer sizes; avoid overly small buffers that cause dropouts.
• If lip-sync issues arise at higher speeds, prefer solutions that process audio in real time with minimal added delay or apply matching playback-rate adjustments to video rendering if supported.
• For scripting/automation: MPC-HC supports command-line options and shortcuts for rate adjustments; combine with system scripts to toggle external processing chains.

The Master Toggle: Using the "Set Speed" Dialog

This is the hidden gem most guides miss. The keyboard shortcuts (Ctrl+Up and Ctrl+Down) cycle through standard speeds but do not always engage the pitch-preserving algorithm. You must use the numeric dialog. How to Speed Up Video in MPC-HC Without

Here is the correct workflow for flawless MPC-HC speed up without pitch: Use consistent sample rates between decoder, filter, and

1. While a video is playing, press Ctrl + Shift + S on your keyboard.
2. A small window labeled "Set Speed" will appear.
3. You will see a checkbox: "Slow down/up audio while keeping pitch" .
4. Ensure this box is CHECKED.
5. Now, enter your desired speed (e.g., 1.50 for 150%, or 2.00 for double speed).
6. Press Enter or click OK.

This forces the internal audio processor (based on the SoundTouch or Bass audio library) to apply real-time time-stretching. You will hear the video play faster, but voices will remain at their natural pitch.

Step-by-step (Windows, MPC-HC)

1. Open MPC-HC and play the file.
2. Right-click video → Filters (or View → Options → Internal Filters).
3. Ensure the audio renderer is set to a renderer that supports time-stretch (try "Default DirectSound Device" or "WASAPI (shared)" where MPC-HC uses its internal audio processing).
4. Use playback speed controls:
   • Press ] or [ to increase/decrease speed, or
   • Go to Play → Playback Rate → choose rate.
5. If pitch changes occur, enable time-stretching:
   • View → Options → Playback → check "Preserve audio pitch when changing playback rate" (if present), or
   • Options → Internal Filters → Audio Switcher/Renderer settings → enable any option labeled "Time stretching" / "Preserve pitch".
6. If no option is visible, switch audio renderer: View → Options → Playback → Output → try "Enhanced Video Renderer (EVR)" or different audio device modes (WASAPI vs DirectSound) until pitch is preserved.
7. Restart MPC-HC after changing major settings.
