Import video recordings to play them back synchronously with the measurement curves and thus increase the significance of your measurements. All common video formats can be imported directly into TranAX.
Experiments with objects in motion or explosions are often recorded with standard or high-speed cameras. Video recordings help to explain or validate measurement data from different sensors recorded by a data acquisition device, such as a TraNET FE from Elsys. TranAX now brings the video recording and the measurement data together, in one program and synchronously.
Synchronization of the Measurement Data to the Video
Video files created simultaneously with measurement data can be played synchronously. While the video is running, a cursor in the waveform display shows the corresponding position in the measurement data. For this to work correctly, the frame rate of the video must be set correctly and a common reference point must be defined correctly.
The frame rate of a normal video is 25 frames per second (fps). Professional and high-speed cameras offer the possibility to record at different and faster (up to 10’000 fps) frame rates. This frame rate must be set in the video display so that the timeline can be determined correctly.
Even if the video recording was triggered by a trigger of the measuring system, temporal shifts may occur or the video recording may not start at the same time as the measurement. To compensate for this, a unique common event must be found in the video as well as in the measurement data. For example, the first contact of two objects should be visible in the video as well as on a measurement curve of a force sensor. If such an event is found, this point in time is set as “Origin” in both displays.
