Once participants participate in a video conference the state of information during that video conference is retained for those participants. At a future time, when those participants again meet in a video conference the state of information that was retained is retrieved and presented for them again in the subsequent video conference based upon their identifiers. Information such as the whiteboard, the chat window, shared files, camera settings, images, background, video recording, etc. are retrieved and automatically presented in the new video conference. Alternatively, a participant may be asked if the state of information from a previous video conference should be retrieved. When a participant joins a conference, the current participants grant permission or not for the current contents to be viewed by the new participant. When a participant leaves the conference, or when they all leave, a triggering condition saves the state. Participants may join in a cross-platform conference and all content from a session in another platform is retrieved. Virtual reality may also be used.
