You can edit and publish the modified video right after your event. Go to Edit category and Recording editing.
Choosing and rearranging clips
Start by selecting your video clip(s). You can add your recorded clip, pre-made videos or record new ones. Drag clips to rearrange them to the right order.
Click the chosen video clip to start editing and a video editor will open.
Editing a video clip
In the video editor you can
- Modify start and ending time
- You can edit the start and time by moving the white arrow.
- Add, remove and move slides. Slides are automatically synced based on the live event. You can also add totally new slides after your event if you want. This is handy if you have spotted a typo or want to add additional slides.
- Add, remove and move chapters. Chapters are automatically synced based on actions in Live control room, but you can still tweak them here.
- Add, remove and move polls. Poll questions and results can be published and timed here. So you can ask the same questions for the VOD viewers as well.
- See the technical details the video, such as resolution, framerate and bitrate. For further modification, see Reprocess clip below.
When you have modified your record, remember to click Process video changes button below category header to process the recording changes.

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.
