You can upload videos for students to analyze using the measurement tools in Pivot Player, or you can embed videos from Youtube. This article is about uploading video for us in Pivot Player. For information about embedding Youtube videos in activities go here.
Pivot Interactives allows teachers to create activities based on a video that the teacher uploads. For example, say a teacher discovers a giant rope swing and thinks it would be good for students to experimentally determine the length of the pendulum. The teacher records a video on her cellphone and then creates a Pivot Interactives activity based on the video. When the teacher assigns this activity to students, students can analyze the teacher's video to complete the activity.
1. Record video
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 an object of known 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.
Once you have a good video, send the video to your computer:
- email the video to yourself from your phone and retrieve the file using your email account while on your laptop
- use Airdrop in IOS or Google Drive to transfer the file to your laptop
2. Create an Activity for the Video
- From your My Library page, click +New Activity
- Enter the title of the activity, the learning objectives, and other notes in the introduction
- Click Add Section to create the first section of the activity.
- Add an introduction to the section, and then add a Instructor Video Upload component to the section as shown below:
3. Upload the video into your activity
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, skip to the instructions at the bottom of the page to convert your video.
Once you have a good video, you can upload it to Pivot Interactives two ways:
1. 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 the button to Choose File.
- Select the video from your camera roll.
- Verify the record and playback frame rate settings: Note: 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
- Click Update to load the video.
- Once the video is updated, it will automatically save. You can now log out of Pivot Interactives on your phone. When you log into Pivot Interactives on your computer, the video will be saved in the activity and ready for analysis.
2. Transfer the video to your computer and then upload it to Pivot Interactives.
- You can email the video to yourself, use Google Drive, AirDrop, or other ways to transfer the video from your phone to your computer.
- Once the video is transferred to your computer, log in to Pivot Interactives and open the activity where you want to upload the video.
- Click the button to Choose File
- Navigate to where the video is stored on your computer and select the file.
- Verify the record and playback frame rate settings. Note: 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.
- Click Update to load the video.
- Once the video is updated, press save.
4. Calibrate the rulers
If you want students to make measurements from your video using rulers, you'll need to calibrate the rulers when you create the activity. Your calibration will be saved and all students will find the rulers already calibrated. On instructor-uploaded video, students do not have the opportunity to re-calibrate the rulers. To calibrate the rulers:
- If the calibration tool is not visible, click tool button in the upper right of the screen, and then the calibration tool button.
- Drag the ends of the calibration tool to align with the reference object in the video.
- When the ends are positioned correctly, type the length of the reference object, with units, into the text box in the middle of the calibration tool.
- You can verify that the calibration is correct by clicking on the ruler tool and measuring the reference object with the ruler.
- When you are satisfied with the calibration, press save at the bottom of the activity.
Here's how the process looks:
5. Complete the activity
- Add instructions for the students, describing what kind of analyses you expect them to do.
- Add additional components to the activity, such as data table and graphs or open-ended questions.
- Save the activity, and assign it to your students.
Optional: Convert video to MOV or MP4 format
Only MOV or MP4 video files can be uploaded to Pivot Interactives. Also, videos must be encoded with the H.264 codec. If you upload a video into Pivot Interactives and it doesn't work 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
Go to Cloud Convert and click Select Files
- Select .mp4, and click Start Conversion
Select .mp4 format and click Start Conversion
- When the conversion is complete, click Download to download the video. Once the video is on your computer, you can return to step 4 to upload the video into your activity.
