It has come to our attention that users have been running into issues when configuring their video widgets with .MP4 videos. If you have been experiencing lag and issues with audio, you will need to convert your video codec to .WEBM. This should now be your extension of choice when embedding videos in your presentation as this has worked best with most displays.

The conversion process is quick and easy. In order to convert your video to .webm format, there are a number of tools available:

Online converters (recommended):




Downloadable applications (this may be necessary if you are working with a large file):

Finally, you can convert your videos via the command line by installing FFmpeg. If you need more in-depth instruction, take a look at this link.

I would also like to take the time to remind our community that Youtube videos can only be used exclusively with our Youtube widget. If you configure a Youtube video in our Video widget, you will run into issues with video and audio as well as scheduling.

If you are using a Youtube video and would like to convert it to .webm format, take a look at the following platforms:



That wraps up our article. If you have any other issues with embedding videos, feel free to leave a comment below or contact us via support. Cheers!

    I am using Ubuntu 14.04.05 LTS 64 Bit on Intel Nuc i3. Somehow the video shows fine with audio on Toshiba TV but for Panasonic and Samsung TV there is no audio.Initially I use mp4 but after reading this thread,  I use webm format using zamzar and firefogg (360p for 1M connection) without success. Any idea how I can check what's wrong?

First thing I would do is check to see if those monitors are muted. If they are not, then connect to them with a mouse and keyboard, and try to go to YouTube or something similar, and play a video that has sound. I think you may find that the monitors themselves may not have audio enabled, and if that is the case, hopefully it is an easy fix.

Let us know how you make out!

Hi Robb,
   I found the problem .The audio on the monitor is fine, I found a settings on sounds related to applications named cubebutils. The audio was set at 0. The when I turn it up everything is ok.  The cubebutils only appear if you open application with audio for example youtube. I am not sure how it internally  works but I never set this setting before
