![]() Percent Speed Change (P) Percent speed change that will convert the duration of the starting clip to the target duration. Decimal values are allow to accomodate frame rates of 29.97 or 59.94, etc. Frame Rate (F) Number of frames per second in the editing timeline where the video clip will be placed or the number of frames per second in the input video. Target Sub-Second Frames (TF) Fractions of a second in the target video clip duration measured in frames. Fractions of a second should be entered the frames field. Target Duration Seconds (TS) Target duration of the video clip in seconds. Fractions of a minute should be entered in the seconds or frames field. Target Duration Minutes (TM) Target duration of the video clip in minutes. Clip Sub-Second Frames (CF) Fractions of a second in the starting video clip measured in frames. Clip Duration Seconds (CS) Length of the starting video clip in seconds. Clip Duration Minutes (CM) Length of the starting video clip in minutes. To calculate the required percent speed change the total input frames, total target frames, and timeline frame rate are needed. Note: you will need this calculator only if you use Camlytics 2.x, the data upload is automatic in the cloud version.PERCENT SPEED CHANGE = TOTAL INPUT FRAMES / TOTAL TARGET FRAMES * 100 Clip Duration Percent Speed Change Variables Make sure that you have 2 or more lines configured in your scene. csv file and then using our calculator below. The whole speed detection process can be automated byĬollecting all Line crossed events, exporting them Therefore, the vehicle traveled with the speed of approximately 45 km/h. Knowing the delta and the distance between lines we can calculate the speed = distance / timestamp delta = 18 / 1.434 ~ 12.55 m/s = 45.18 km/h In our example there are two events with object ID = 1 and the timestamps are 5.024s and 6.458s. The distance is 18 meters in our case.Īs vehicles travel through two lines, every vehicle will have the same object ID for both events generated by those lines. ![]() The greater the distance the more precise the speed calculation will be. Measure the real distance between those lines. Step 2: Measure distance between the lines ![]() See how it looks in action, you'll be able to detect the speed for two vehicles in the following video: Make sure that moving vehicles are always detected and both lines generate events for each vehicle. Time calc for video speed full#Place two lines one after another so that they cover the full vehicle travel distance. Make sure you calibrate it properly so that all moving objects are detected correctly and in time. With multiple time periods speed comparison, average vs max speed comparison, as well as filtering detection results in a speed data table.Īdd any video source where you want to detect speed. Newer cloud solution also has the same feature with a significant advantage - the speed data isĬollected automatically, allowing building real-time charts This tutorial covers the configuration of the speed detection for older, Camlytics 2.x software. For instance, you can detect speed based on two lines in your scene. ![]() This data can be used to find linksīetween different scene events. Video source - IP camera, webcam, NVR, video file or video folder, has a lot of properties - source ID, timestamp, videoįile time, object ID, origin, channel ID, type and others. Zones allow a lot of custom data manipulations.Įvery single analytical event that comes from any Such a powerful events triggers, as Lines and Line crossed, Zone join, Zone left and others. During video processing, metadata events are generated, such as Time calc for video speed software#Camlytics software processes video streams from the range of video sources - IP cameras, webcams, video files, etc. ![]()
