How does PecPIR work?

Pec PIR allows to record data for Partial Interval Recording, Frequency Count, and Momentary Time Sample.

PecPIR helps you with scoring videos by splitting a running video file in pre-set time intervals called cycles.

Open PecPIR and use the "Open movie file" to select the video file from you computer. You can use the Player buttons (start, pause, drag video left and right) to seek start and end position and using Set start/end buttons. The textbox close to "Set end" may be used to type endtime as hours: minutes:seconds,decimals. You can either write the end time time and press "Set end" or slide the player cursor and press "Set end".

During your video observation you can use the keyboard keys and numbers to mark the moment when target behaviour occurs. You can also choose later if your data will be considered as PIR or Frequency Count. This is regulated by the button Partial interval recording / Frequency count.

Recording events while in Momentary Time Sampling mode briefly pauses the video at the end of each cycle allowing to press one key for each behavior that was present at the end of the cycle. Press "Resume recording..." to unpause the program after scoring.

If you make any mistakes you can click on the mistakenly added entry in the left timing list to remove it. If you need to add entries after the first scoring, you can restart the recording process by pressing "Go to start" to add entries.

We suggest to fill in the table on the right with a behavior list and relative character before you start recording. This table can be saved and re-used for different videos.

You can stop data recording by pressing the pause button and then restart it continue exactly from where it was paused. When the video reaches end time, the program will automatically stop.

Each key that you press during recording draws his character in the timeline, so you can see each behavior code in the timeline.

To save the scoring use File - Save Json. This json file allows to re-open the same setup and recordings.

You can export data to a spreadsheet, either Libreoffice or Excel. During this spreadsheet rendering, the program will calculate aggregation of the data respecting the amount of seconds you have typed in the text box "interval". So you will have a row in spreadsheet every "interval" seconds.

During this rendering, the program will export according to the choice you have selected in "Partial interval recording / Frequency count" radio button. So the resulting number may count either how many times a behavior was present in a cycle, or if it was present or not at all, counting 1 for present and 0 for not present.
