How to Use RecMaster, a Screen Recorder with Timer & Auto-Stop

Manually monitoring a recording is inefficient. To maximize your productivity, you need a high-quality screen recorder with a timer function. This tool ensures that whether you are archiving a Zoom meeting, capturing a scheduled broadcast, or recording a long gameplay session, you have a way to limit recording time precisely to save storage space and battery life.

Nothing is more counter-productive than recording an hour of dead air simply because you weren’t at your desk to hit the “Stop” button immediately after an event finished. Not only does this fill up your hard drive with massive files, but it also adds unnecessary work to your post-production workflow, forcing you to trim silence from every video.

The solution is using a screen recorder with a timer function. Unlike a “Scheduled Recording” (which starts the recording for you in the future), a “Timed Recording” or “Auto-Stop” feature allows you to start recording now and tell the software exactly when to quit.

In this guide, we will show you how to set a specific recording duration in RecMaster so you can walk away from your computer with total peace of mind.

Why Use Auto-Stop Instead of Manual Recording?

Before diving into the “How-to,” here is why using the auto-stop timer is a smarter choice for professionals:

• Precision Archiving: If you know a lecture is exactly 50 minutes, you can set the timer for 55 minutes to capture the end without recording hours of silence afterward.

• Storage Management: Prevent accidental “over-recording” that fills up your disk, which is especially critical if you are recording in 4K or high frame rates.

• Battery Preservation: On laptops, stopping the recording automatically reduces unnecessary power consumption.

Method 1: Setting a Time Limit (Duration) using your Screen Recorder with Timer

This is the primary method for users who are at their computer now and want to use a screen recorder with a timer to stop the capture later.

Note: You must configure this setting before you press the record button.

1. Open RecMaster and select your recording mode (e.g., Full Screen, Custom Area).

2. Navigate to Menu (the three lines in the top right) > Auto Recording > Auto-record.

3. In the “Auto-record” section, look for the End recording automatically option.

4. Check the box and enter your desired duration in the time field (Format: HH:MM:SS).

   • • Example: If your show is 1 hour long, enter 01:05:00 to include a 5-minute buffer.

     • You can RecMaster to do nothing or turn off the computer.
     • You can also set the timer to effect only once or always in effec.

5. Click Close.

6. Start your recording as usual by clicking the REC or Alt + 1. RecMaster will now count down and automatically stop saving the file when the timer hits zero.

Method 2: Setting a File Size Limit

Sometimes the limitation isn’t time, but storage space (e.g., trying to fit a recording onto a 4GB USB drive).

1. Go to Menu > Auto Recording > Auto-record.

2. Instead of entering a time, look for the File Size option under “End recording automatically”.

3. Enter the maximum size (e.g., 1000 MB for ~1GB).

4. RecMaster will monitor the file size in real-time and stop the recording exactly when it reaches your limit.

Notes: Please don’t forget to click the Rec button or Alt +1 to start the recording.

Comparison: Auto-Stop vs. Task Scheduler

Users often confuse these two features. Use this table to decide which one you need:

Pro Tip: To use the Task Scheduler, go to Menu > Auto Recording > Schedule and create a new task with a specific Start and End time.

Advanced Tips: Power & Shutdown Settings

To ensure your timed recording goes smoothly, you must check your computer’s power settings.

1. Prevent “Sleep” Mode Interruptions

If your computer goes to sleep, the screen recording will stop or fail.

• Windows: Go to Settings > System > Power & sleep settings and set “Screen” and “Sleep” to Never (or a time longer than your recording).

• Mac: Go to System Preferences > Energy Saver and prevent the computer from sleeping automatically.

2. Auto-Shutdown After Recording

Want to record a movie late at night and have your PC turn off when it’s done?

• In the Auto-record menu (where you set the timer), look for the After recording dropdown menu.

• Change “Do Nothing” to “Shut down”.

• RecMaster will now finish the recording, save the file, and immediately power down your machine.

• To avoid unexpected errors that may prevent RecMaster from saving your recordings, you can enable automatic file segmentation via Menu >> Auto Record >> Segment. By setting a fixed duration or file size, RecMaster will save recordings in segments, ensuring that even if a crash or sudden power-off occurs, you can still retrieve the auto-saved files.

Frequently Asked Questions (FAQs)

Can I set my screen recorder to stop automatically?

Yes. In RecMaster, use the “Auto-record” feature found in the main Menu. You can define an automatic stop point based on recording duration (time) or file size (MB/GB).

Does screen recording continue if the computer sleeps?

No. Most screen recorders, including RecMaster, rely on the graphics card and display being active. If your computer enters Sleep or Hibernation mode, the recording will pause or terminate. Always set your computer’s power settings to “Stay Awake” for the duration of the recording.

How do I record my screen for a specific amount of time?

Go to Menu > Auto Recording > Auto-record. Check “End recording automatically” and input the specific duration (e.g., 30 minutes). Start your recording, and it will capture exactly that amount of footage before stopping.
