It takes just a few minutes for students to upload their own videos to analyze in Pivot Interactives. Here's a video showing how easy it is for students to upload video into Pivot Interactives:
Pointers for recording useful video:
Record in an area with lots of light. This will reduce the exposure time and reduce motion blur.
Hold camera still; use a tripod, or rest camera on stationary surface.
Point the camera perpendicular to the direction of motion.
Make sure to place a scaling object", an object of know size, in the video, with the object the same distance from the camera as the moving object. You'll need it to scale the rulers when you analyze the video.
Make your scaling object something that takes up a large part of the screen. If your scaling object is too small on the screen, this will make it difficult to calibrate the rulers.
Upload the video to Pivot Interactives
Only MOV and MP4 files can be uploaded into Pivot Interactives. Also, video files must be encoded with the H.264 codec. Video from Apple iPhones and Android phone can be directly uploaded into Pivot Interactives. If you are not sure, just upload the video to see if it works. If the video does not display after being uploaded, try converting it to MP4.
Once you have a good video, you can upload it to Pivot Interactives two ways:
Upload the video directly from your phone into Pivot Interactives.
Log into your Pivot Interactives account on your phone, and open the activity where you want to upload the video
Click Choose File.
Select the video from your camera roll.
Verify the record and playback frame rate settings:
Most phones record video at 30 frames per second. But slow motion can be 60, 120, or 240, or even 960 fps. Check your phone settings to find the recorded frame rate.
Most phones encode video for playback at 29.97 fps, but there are some exceptions. You can check your phone's settings to verify the frame rate.
Analyzing video in Pivot Interactives
Once the video appears, you can use the Pivot Player tools to analyze the video, following your teacher's instructions in the activity. Here are some tips:
Drag the arrows on the calibration tool to the ends of the object of known size in the video.
Type in the length of the object of known size in the text box on the calibration tool.
Here's how it looks:
Once you've completed the calibration, you can drag ruler or grid, rotated them, or expand/shrink them as needed. Your calibration settings are auto saved so you can continue work when you log back in.
The stopwatch can be used to measure time in the same way you would in any other Pivot Interactives video. As long at the recorded frame rate and playback frame rate are selected correctly, the stopwatch will give accurate time measurements.
Now you can make measurements of position and time in your video. Your teacher will give you more instruction about what to do next.
Optional: Convert video to MP4 or MOV format
If you have a video that is not MOV or MP4, or is encoded using a different codec, you can use free online conversion tools like Cloud Convert to quickly convert any video file to .mp4. Here's how:
Go to Cloud Convert
Click Select Files
Select .mp4, and click Start Conversion
When the conversion is complete, click Download to download the video.
