Optimum settings for MP4 h.264 kaleidascope motion graphics footage

I have made a video that is going to play behind a band on a stage on a 16x9 ft video screen 1350x765pixels 2.9 mm pixel pitch at a concert venue. The video is kaleidoscopes and motion graphics with color changes and blend modes. The video is 15 minutes long MP4 and i've presently rendered it as H.264. My bitrate settings are Target Rate 10 MBPS and Maximum Bitrate. VBR, 1 pass. The file is 1GB and it looks good on my PC. Max filesize as stipulated by the venue is 10GB (some bands might have 2hrs of video).

Should I consider elevating these Bitrates, and could that improve the quality in a good trade-off? Its important to me that the file be very compatible - my worst nightmare would be to show-up to the venue and the file to not be playable for some codec issue.

I don't spot much compression in the current video in transistions between kaleidascopes and image, but the screen is going to be much bigger.

I suggest investigating the HAP codec.  It's designed for large screens and optimized for playback.  Check with the venue as they may already have proper specs for you.

The show is this weekend and the venue had approved I use H.624 so I'm a little nervous to change codecs at the last minute. I read about HAP and it looks very interesting. I'll look into using that after this show.

I will report that I exported a version of H.264 and set the Bitrate up to 30. I saw a noticeable improvement on the detail as it transitioned between kaleidoscopes and overlayed complex graphics. The file size moved up to 3 GB (which is less than the 10 max) and I didn't have any performance problems on my PC. I think I'll go with that.  Thanks so much for the word on HAP. I'll check it out.
