Advanced settings
Hotkeys for efficiency
Enable hotkeys by pressing h or clicking editor hotkeys (h).
Hotkeys enable efficient editing. For example, zooming helps find the perfect timing for elements.
Toggle the help menu with h while the video editor is open.
Raw log for tweaking the timings
You can open the raw logs of different elements by clicking the Raw log button in different categories. Raw log allows you to see all the category elements and their exact timings.
In Raw log you can modify the exact timings of slides, chapters and polls. The syntax follows the similar logic in all categories, the first number is always 1.

Click Save to save the changes.
Reprocess video and/or audio
You can modify the video bitrate and resolution by clicking Reprocess clip.
You can modify:
- Video bitrate
- Video resolution
- Audio bitrate
- Audio sample rate
To transcode the video with chosen settings, click Re-transcode video button.
How to transition between different video player modes?
You can change the video player view during your recording, if you want to transition between only video and video + slide views. We have used the feature for example in our own Videosync demo, when we wanted to show only the screen capture and not slides next to it.
You can access the video player mode editor with “Video player mode log” button in editor. You will see a similar editor as with raw logs:
- enabled: Which video player mode you want to enable. 0=video only and 1=video+slides
- time: exact time in seconds when you want to change the mode Click “Save” to save the changes.
