Situation

Original videos are usually very large and should be prepared optimally,
to be played smoothly and for the purpose to save disk space.

If you do not have a professional encoding software (Adobe Media Encoder etc.), we recommend the open source software "Handbrake" which is available for free: https://handbrake.fr/.
As always, we do not assume any liability for the websites/content of third party providers.

This is just an example. There is certainly good other (free) software for this purpose.

Checking the video settings

To get an overview of the original video, it is recommended to check the existing settings:

Windows: Right mouse button on the video files and then Properties, then Details.

MacOS: Right mouse button and then on Information

In the following section you can compare the values with the optimal values and, if necessary, re-encode them to save disk space and ensure optimal playback: 
 

Optimal settings for videos

1. Codec
Select the correct codec. Since most browsers support this format use this format
we recommend to export your video always as: MP4/H.264

2. Resolution
The videos should work on desktop PCs, tablets and cell phones.
They should be responsive and look good at the same time. 
1080p is recommended: 1920 x 1080 pixels / web optimized
 

3. Bitrate

• If the video is not very long: 3 - 8 megabits per second
• For long videos (30 min and more) the bitrate should be between
  1 - 3 megabits per second

Our tip: For static videos (example: PowerPoint slides with audio from off-screen) you can try 1 megabit. If necessary, increase the bit rate. 
 

4. Frame rate (frames per second):

• Static videos: 25 - 30 frames per second.
• A lot of motion in the video: 60 frames per second
