Premiere and AfterEffects can output to MP4 at a maximum bitrate of 50Mbps = 6.25Mb/sec. This should make it pretty difficult to spot compression artifacts.
Which video editor are you using if I may ask?
If you won the competition and we needed a completely lossless version of the competition entry (assuming that there were some compression artifacts on the video that you had sent us), we would probably just ask you to render the video as still images.
The point of having the MP4 rule is just that we would prefer a high quality video, so that we don't have to ask you to render still images if you won the competition. Obviously it's still possible to create an MP4 with a very low bitrate and a lot of compression artifacts, so if I were to clarify this rule, it basically just means that we prefer a high-quality video, not a grainy highly compressed one

That being said, bear in mind that it's the idea/concept and the quality of the models/textures/composition as a whole that matter in this competition.
Make our jaws drop and don't worry too much if your video is compressed a little
