Dear Datavyu support In our research team, we have been trying to code our data with datavyu and ran into some problems. We use Mac OS X 10.9.5 and Videos in .mp4-Format (around 100-150 MB) that we recoded with HandBreak (from .mpg) as suggested on your website. The problem is, that when we are coding a video sequence (with the "snap region"-function) and then want to go back to an earlier sequence in the same video and double check the already coded data, the on- and offset times are no longer correct. That is, the times in the data sheet are still the same (we verified with a screenshot), but it seems like the video is no longer synchronized with the already coded data. This happens even if we don't close the video in between. Do you have an idea what could be causing this inconsistency? many thanks for your help

This is a known problem. We apologize for the inconvenience. It is something we hope to fix in the next version of Datavyu 1.3.5. There are a few potential work arounds.

Know that the coded times are correct but that the portrayal of the video is not finding the correct time (even though the controller is updated)

To jump to the correct onset, you could use the "jump back" key and set the time to something that will bring you to the beginning of the cell.

You can also reset the incorrect display by leaving the desired cell, jumping to the beginning or end of a different second cell to reset Datavyu's display so you can then go to the original cell and jump to the onset (plus key) or offset (shift plus).

Apologies that these are the only workarounds right now.
