Slidesync can record the stream for later viewing. The slides will be displayed next to the recording, just like during the live event, and they will be synchronized to the recording.
Recording is on by default. It can be toggled in the Basics, or in the Live Producer, before starting the event.
Note: in both views there is the option to automatically publish the recording, disabled by default.
Once the event is over, there is often a little bit of editing needed before a recording can be published. For example, it often happens that the stream is started before the event, and the first few seconds need to be trimmed away. Same with the end of the event, where there might be some recorded footage you want to remove. You can trim the video quite precisely within SlideSync using the Edit Recording tool.
You can also manipulate the slides timing by dragging the slides on the timeline. You can even replace the slideset with an updated one, to fix a typo or a layout mistake.
