ryste3d: If you're playing 5-6 x 1080p MP4s with a high bitrate, your PC might begin to struggle with the decoding. It's exactly the same in Adobe Premiere if you have 5-6 overlapping 1080p videos in the timeline.
My advice is to lower the resolution of the MP4s for the video screens, and reduce the bitrate.
To determine what resolution you'll need, have another look at your video and locate the clip where the JCDecaux screens take up the most space measured in pixels. So if they'll only ever occupy, say 600x400 pixels when the camera is close to them, simply convert the MP4s to that resolution and replace them in Lumion. If you're using higher resolution videos than that, you're wasting valuable bandwidth.
