Logger Pro can import videos of your experiment. You can then synchronize the video to your data, so when the experiment is replayed, the data and video will be viewed together. To perform a synchronization, you must be able to identify a time on the graph that corresponds to a particular frame in the video.

A tutorial covering movies is available. Choose Open from the File menu, then look in the Experiments folder to access it.

When you are ready to match your data to activity of your movie, click  from the bottom of the movie object.

You can select which Data Set you want synchronized to the video.
 
If the Synchronize Video Analysis Data Set with Selected Data Set check box is checked, the times generated by the video analysis tool will be from the selected Data Set instead of the raw times in the movie.

The Graph Time is the time you have selected from your graph (or manually entered in the field) that best corresponds to the chosen frame (or manually entered Movie Time) of your movie. 

For example, you might have a movie that starts 0.75833s (as shown above) before your sensor data. Sync the movie to the sensor data using some event in the video. Now when you do video analysis for the movie, the time entered for a point on the first frame will be -0.75833s if the box above is checked, since that corresponds to the graph time. If the box is not checked, a time of zero will be entered for the first frame.

Check the box next to Use This Synchronization In Video Capture to apply the synchronized offset to subsequent captured videos.

Synchronizing Your Movie with Existing Data

Data collected with a computer can easily be synchronized with a movie. A tutorial covering synchronization is available. Choose Open from the File menu, then select 11-1 Working with Movies.cmbl to access it.

1. From the Insert menu, choose Movie and select the movie you want added to your page. Supported movie formats are Video clip (.avi), QuickTime movies (.mov), or any movie that can be supported by QuickTime.

2. Click the Sync button  to open the Movie Synchronization dialog . To synchronize the movie with the data, you need to first find a spot in the data that is easy to identify in the movie, e.g. the time when a ball reaches the peak of a toss. Click the graph at the time you are using to sync. Next, use the slider and the next frame/previous frame buttons to find the frame in the movie that corresponds with the data point you identified in the graph.

3. Choose the Data Set that holds the data being synchronized to the video.

4. Click OK.

1. Import the data.

2. Perform this step only if you imported data from a TI calculator. If you did not, skip to the next step. Data imported from a calculator have the time data in a column that gets labeled "L1" which then must be renamed to "Time" before attempting to synchronize the data to a movie.
   

3. From the Insert menu, choose Movie and select the movie you want added to your page. Supported movie formats are Video clip (.avi), QuickTime movies (.mov), or any movie that can be supported by QuickTime.

4. Click the Sync button . The Movie Synchronization dialog will be opened. To synchronize the movie with the data, you need to first find a spot in the data that is easy to identify in the movie, e.g. the time when a ball reaches the peak of a toss. Click the graph at the time you are using to sync. Next, use the slider and the next frame/previous frame buttons to find the frame in the movie that corresponds with the data point you identified in the graph.

5. Choose the Data Set that holds the data being synchronized to the video.

6. Click OK.
