Optimise your media files for the web
Aside from the file format, it is important to optimise your media files in order to reduce as much as possible the loading time of your project online.
The weight of a media file is defined by it’s resolution and output. The higher the resolution and output, better the visual quality but the element will also be heavier. We advise the following settings to have the best compromise for quality and quantity.
N.B: Keep in mind that the values we quote in this article are only given as examples. It is important to adapt them according to the use you’ll make of media elements. For example, a video displayed full screen won’t have the same resolution as a small one, integrated inside a graphic composition. You must adapt these settings according to your own needs.
Video settings :
- Frequency : 25 image/second
- Video output : 2000 - 5000 kbit/s
- Audio output : 128 - 320 kbit/s
- Resolution : 720p maximum (1280*720 pixels)
Audio settings :
- Sampling frequency : 44 100 Hz
- Output : 128 - 320 kbit/s
Image settings :
- Definition : 72 - 150 dpi
To automatically optimise your images, we using very simple tools which remove in one click certain superfluous data (metadata, colorimetric profiles…) to save a couple kilobytes.
- For Windows, use PNGGauntlet
- For Mac, use ImageOptim
