Tips to speed up Telemetry Overlay video integration

Learn how to optimize the process of integrating Protern.io data into video using Telemetry Overlay

Telemetry Overlay is a user-friendly, cost-effective program to overlay data onto video. This article provides some tips and tricks to speed up the process of integrating data across multiple videos.

To learn more about the program, we suggest the Telemetry Overlay Facebook page. Video tutorials are posted regularly and the developer actively supports the product via the Facebook group.

This article includes the following:

Increasing render speeds

Optimizing the process of working with multiple files


Modifying the export resolution

Modifying the export resolution will speed up the rendering of the final video significantly. For video analysis, often a resolution of 1280x720 is adequate. We suggest experimenting with different resolutions.

Note: We recommend keeping the original frame rate as that will help with frame-by-frame analysis.

  1. Select the Project section
  2. Select the resolution that works best for you (1280x720 is our recommendation)

Changing the gauge update rate

The gauge update rate can make a difference to the rendering speed of the video. For data captured by the Protern.io Sensor, we don't recommend going below Half as it will remove the benefit of capturing high-speed data.

  1. Click on the gear icon
  2. Under Advanced, select a Gauge update rate

Change the render speed and encoder

Modifying the render speed in the Export section can help speed up the rendering. Simply drag the Render Speed slider to the right. 

Changing the encoder can potentially make a difference to the render speed as well.


Modify the end points to shorten video

By trimming the beginning and end of the video, you can speed up your rendering times.

  1. Select the Export section

  2. Drag the Export In slider to where you want to start the video. Repeat for the Export Out slider
  3. Click Export

Turn off Look for Telemetry

Telemetry Overlay by default will look for GPS, accelerometer, speed data embedded in the video. This information is found in GoPro and some drone videos.

We suggest turning off Look for Telemetry to save time if the following is true:

  • Your cameras do not collect any GPS data
  • You don't use the speed and location data from a GoPro or drone

Here's how to turn off the feature:

  1. Click on the gear icon
  2. In the Advanced section of the settings, turn off Look for telemetry in videos


Turn off Optimize video

When a video is loaded into Telemetry Overlay, it will automatically optimize the video. This can take a few minutes depending on the resolution and length of your video.

We suggest turning off Optimize video if the following is true:

  • Your focus is to quickly find the sync point in the video and export the video - i.e. not watch the video in Telemetry Overlay
  • Video from your cameras appear just fine in Telemetry Overlay when you have skipped the optimize process in the past - i.e. HEVC (h265) video will need to be optimized to show up

Here's how to turn off the feature:

  1. Click on the gear icon
  2. In the Advanced section of the settings, turn off Skip video optimization


Change the default pattern

You can save time by having Telemetry Overlay automatically load your preferred pattern. You can always change the pattern, or load in a different one.

  1. Click on the gear icon


  2. In the Advanced section of the settings, click on Custom Pattern and select your pre-saved pattern

Note: You can make your own patterns and save them the Gauges section under Pattern.


Use the Export Queue

The paid version of Telemetry Overlay has the ability to queue, or batch, your files for export. This means you can sync multiple videos and then export them all at once while you are at dinner or away from your computer.

  1. Click the plus beside the Export button, then click Add to Export Queue

  2. Start a new project and repeat step 1 until you have all of your videos ready.
  3. Once you are ready to export all your videos, click the Export Queue icon in top right of the program
