Automatic Scrolling Capture is a convenient tool, but unfortunately, it may fail under certain circumstances. If that’s your case, try Manual Scrolling Capture: it works around compatibility issues caused by the third party software, macOS configuration, or unconventional scrolling behavior of the target apps.

To enable manual scrolling capture:

To enable manual scrolling in Shottr, first of all, make sure that you run Shottr v1.8.1 or newer (you could check in menu Shottr → About). When it’s done, enter this line in your browser, and hit enter: shottr://settings/scrolling/manual/enable

To take a manual scrolling capture:

1. Select “Manual Scrolling Capture” in the menubar icon menu:

   

2. The mouse will turn to a crosshair. Select the area that you want to scroll through. For example, if you want to take a screenshot of a webpage, select the entire browser window. It is okay to include that parts that don’t scroll (for example, the browser window with title and borders), as long the scrollable content takes up the majority of space in your selection. You’ll be able to crop the resulting image later.

3. The screen will darken, leaving out the area that you selected. Start manually scrolling the content up or down. Don’t scroll too fast: the optimal speed is one screen of data per second. You can go slower, but not faster. If you go too fast, the result might come out wrong, or the capture may stop prematurely.

4. If you stop scrolling for longer than three seconds, the capturing process will stop.

5. When you’re done scrolling, press Esc to stop the capture, or just wait for a few seconds, and the process will stop automatically.

6. Once you get your screenshot, you may want to crop it: select the area in the editor with your mouse, and hit Enter.
