TechSmith Relay (Hosted): TechSmith Fuse Best Practices


What are the best practices for recording content with TechSmith Fuse?


TechSmith Fuse is a mobile application that shares media directly to TechSmith products. To learn more about best practices for TechSmith Fuse, see:

Support for High Efficiency Video Coding (H.265)

TechSmith products do not support H.265 content. Content recorded with the native Camera app on iOS or the native Camera app on certain Android devices (with the H.265 video codec) and imported into TechSmith Fuse will not work with TechSmith Relay, Snagit, or Camtasia. The following devices have the ability to record with the H.265 video codec:

  • iPhone 7 or iPhone 7 Plus or later
  • iPad (6th generation)
  • iPad Pro (10.5 inch)
  • iPad Pro 12.9-inch (2nd generation)
  • Samsung Galaxy S9 or Samsung Galaxy S9+

Please follow these guidlines when creating content with TechSmith Fuse on these devices.

iOS Only: H.265 content that is imported into the Fuse Library will be re-encoded to H.264. As a result, it may take longer to import H.265 recordings.

Record With Fuse

Content that is recorded directly in the Fuse app is recorded using the H.264 codec, and is supported in TechSmith Relay, Snagit, and Camtasia.

Change the Video Format on the iOS Device

To avoid problems with importing content from the camera roll, change the settings on the device to record with the H.264 codec. H.264 content is supported in TechSmith Relay, Snagit, and Camtasia. To change the video format on the iOS device:

  1. On the iOS device, open the Settings app.
  2. Tap Camera > Formats.
  3. Tap Most Compatible.

See this article from Apple for more information on the various video formats.

Change the Video Format on a Samsung Galaxy S9 or S9+

  1. On the Android device, open the default Camera app.
  2. Tap the Settings cog.
  3. Tap Video Size.
  4. Put High efficiency video into the off position.

Re-encode the Video

If a video was created with the H.265 codec, the video can be re-encoded to H.264 so that it can be used with TechSmith products. A free program that can be used to re-encode the video is Handbrake, which can be downloaded from the Handbrake web site. Watch the tutorial below to learn how to re-encode a video in Handbrake.

Avoid Black Bars

To avoid black bars from showing on the sides of the video, be sure to start the recording with the device in the correct orientation (landscape or portrait). A portrait video imported into a landscape project project (and vice versa) may result in black bars showing in the video since the content does not match the canvas.


Hosting services such as YouTube and Vimeo only display content in wide screen format (landscape). So, any video recorded in portrait and uploaded to these services will show black bars on the sides of the video. To avoid this problem, start the recording in landscape.


Upload Content to TechSmith Relay

Large videos will take time to completely upload to TechSmith Relay. Here are some tips for uploading content to TechSmith Relay from Fuse.

Keep Fuse in the Foreground

On mobile devices, if an app is pushed to the background, then after some time data will stop being sent/received from the app. This will cause the upload from Fuse to pause. Kep the Fuse app in the foreground to ensure the content is uploading (if the upload paused, re-opening the Fuse app will resume the upload).

Connect to WiFi

A reliable data connection will improve the upload performance to the TechSmith Relay service.

Plug in the Device

Keep the device plugged in to a power source so device does not shut down in the middle of an upload. If the device does shut down, the upload will resume once the device reconnects to a data connection, and Fuse is re-opened and kept in the foreground.

Stay Up to Date

Make sure that the device operating system, and all of the apps are up to date. Consult the device's support documentation for information on how to update the operating system and the apps.
