I just want to put it out here. We are investigating the possibility for recording timestamps in high-speed video recordings to synchronize with MEG data. This is very helpful for epileptic workups. thing visualizing video with the data in databrowser. When I know more Ill post it here. Best, Stephen

Assigned to a named person, to keep this on the radar.

I received MEG data plus audio and video from Fanny. The recording and synchronisation is done with https://github.com/andreyzhd/VideoMEG.

I shared the first implementation in r10845. In the next commit I also added cfg.anonimize to place a bar over the eyes (for demonstration purposes, probably not relevant for normal use). mac011> svn commit Sending ft_audiovideobrowser.m Sending ft_databrowser.m Transmitting file data .. Committed revision 10845.

Dear all, I have added some of you to the CC list of this "bug" (i.e. feature request) so that I can keep you posted on the progress. There is now support for the NatMEG videomeg data in FT_DATABROWSER (linked to the MEG) and in FT_AUDIOVIDEOBROWSER (for only looking at the video based on triggers in the MEG). I will make some documentation online, probably as a "video" section under http://www.fieldtriptoolbox.org/reading_data#getting_started_with_other_data Figuring out and improving the synchronisation at the DCCN is still work in progress (Uriel is onto it). best Robert

note to self: One approach (with the EEG/MEG data central) is implemented with cfg.audiofile cfg.videofile and a right-mouse-button function in FT_DATABROWSER. Another approach (with the audio/video central) is implemented in FT_AUDIOVIDEOBROWSER.
