Each video capture is saved as a separate file when the associated Logger Pro file is saved. The video file names will begin with the name entered in this field, and a number is appended to successive video capture files. Most users will not need to adjust this entry.
Adjust Video/Data
Synchronization
The option Adjust Video/Data Synchronization allows you to correct for typical differences in video and data startup times. The difference is usually less than half a second, so if this discrepancy will not affect your experiment and analysis, you do not need to use this option.
To adjust the video/data sync, you will need to first determine the time offset between the video and the data streams. Do this by collecting a run in which there is some event that can be identified unambiguously in both the video and data streams. For example, you might take a video of your finger tapping a force sensor, or your thumb covering the end of a light sensor. Use the methods found in the Sync Movie to Graph page to determine the time offset. If the Movie time from the Movie Synchronization dialog is always greater than the Data set time, then the video is said to be behind the data. Enable Adjust Video/Data Synchronization, choose “behind” from the menu, and then enter the appropriate time difference in seconds. Typical values are around 0.500 seconds, with the video behind, but this will depend on your computer, your camera, and how busy the computer is when a capture is started.
