Video post synchronization

To include the high speed video in

, only few steps are necessary. After acquisition of the video file and the Dewesoft

data, please copy the *.avi camera file to the directory where the Dewesoft data file is located.

[Video available in the online version]

After this, open

and enter the Analysis mode. Select the data file and option

Post-sync. video

.

The next step is to select the video file that you want to import.

Double click on the file to open it and

will recognize that this file has no synchronization information included and will

ask to synchronize it manually.

It will automatically recognize how many frames are stored in the file. Please enter the correct Frame rate of the camera
(sometimes the .avi files hold the correct values, but most of the time not). In the info field Video size, you will enter the video length
in seconds. Also, enter how many pictures were taken before the video trigger - Pre trigger - occurred. You can enter it in frames,
seconds, or milliseconds.
