Speed of delivery, bandwidth usage and device performance are influenced by the size of the content within the layouts for playback.
As such we have outlined a few file size recommendations below to help you get the best performance from your signage.
Here's an example of why image sizing is so important:
Let's imagine you've taken a photo and want to show that on your signage. IMG_910.JPG is 2.14MB in file size and is 3456 x 2304 pixel dimensions.
You upload this to your account and then want to be place it in a zone of 590px by 380px dimension - the image is nearly six times the size of the zone.
Any device this gets published to needs to try to load 2.14mb of image data into the zone. It then has to resize it to almost a sixth of it's size and then animate that into the zone and play it for the specified time based on your playlist settings.
... this is quite a lot for some devices to handle and if you start to add 10's or 100's of images of the same spec, the device is going to be overworked very quickly.
Best practice for images is to:
- Reduce the image pixel dimensions to be no larger than the zone you will be placing it in
- Ensure it is rendered as 72 dpi resolution
- If as a .jpg file, try rendering at 85% max quality this will give the same visible quality on your screen but reduce the file size
- Try to keep them below 585kbs, if feasible
File size will depend on length of video however we would recommend rendering any video as an .mp4 and encoded using H.264 to reduced the file size as much as possible. Default maximum upload file size is 133mb, however if you need to upload bigger file sizes, a large file uploader is available on request.
