In the Quality section, you can adjust the quality of the images, sound and video inserted in the quiz. The higher the quality of the media, the larger the size of the output files.
In the quality settings, you can select one of the ready-made presets for the following situations:
- For displaying quizzes in high quality
- For standard viewing
- For low-speed connections
You can also configure your own quality settings and save them as a separate preset.
When creating a custom preset, you can change three parameters:
- Image Compression
- Video compression
- Audio Compression
Smart compression automatically chooses which type of compression to apply to a particular image in the test: lossy or lossless. The result is the most optimal in terms of quality and size.
Lossy compression will save all images from the quiz to .jpg format with the specified compression settings.
Lossless saves images to .png format. This will ensure the best quality, but the output files will be large.
You can set the sound quality in your published quiz from 0% (low quality and small size) to 100% (high quality and size). The recommended quality is 50% or higher. Note that the higher the audio quality, the larger the final file size.
Note: Audio compression settings affect the audio quality of video files as well.
You can set the video quality in your published quiz from 0% (low quality and small size) to 100% (high quality and size). The recommended quality is 50% or higher. Note that the higher the video quality, the larger the file size will be.
You can save a custom preset by clicking the Save Preset button. To delete a custom preset, click Delete.
Enter a name for the profile and click OK.
The saved profile will be added to the list of available profiles. You can select it when publishing all the quizzes on your computer.
