Here is some guidance I received for a similar issue:
Ae/Pr/Sg effect to auto-correct fluctuating Y-levels? -
Make sure the timeline is the active panel before trying to export.

QuickTime uncompressed 4:2:2 YUV works with Expression Encoder 4. I cannot get EE4 to recognize AVI V210 YUV files. Uncompressed “None” should work, but 8-bpc RGB is susceptible to banding and blocking when converting from/to 8-bpc YCC.

Not sure what 1xCU means; please clarify. Are you A) splitting the frame into three segments like a video wall matrix, or B) showing the same video on three displays with different resolutions on each?

YouTube videos are compressed at a very low bitrate. There is too much detail in your image to be encoded accurately. Consider simplifying the image if the video is intended for web streaming. Otherwise, post a higher bitrate version on a different website.

[sam mayfield] “I have tried many variations in compressor and straight from FCP but nothing is working. “
A 2GB file constraint allows for an average video bitrate of about 4.5Mbps. That should produce a good H.264 file at 1280×720-23p. What export settings did you try? What issues were observed (banding, blocking, color shift, other)? It would be helpful if you could post a short clip or screen capture along with the export settings.
[sam mayfield] “I have one version that sort of looks ok but it is squished at 768×576.”
Sounds like your media player isn’t compensating for rectangular pixels. Encode using square pixels at 1024×576 or 854×480 instead.

For distributed files set Format to H.264 rather than QuickTime. ProRes is an intermediate format; you will need a very fast computer to play 1080p ProRes files in real time. Try a test clip, if desired.

Key Frame Distance will be OK on automatic, but bitrate and multiplexer directly impact the artifacts. Try exporting a short clip using the settings listed above with 20Mbps Target bitrate and 35Mbps Maximum bitrate. If required you can boost Target bitrate to 30-35Mbps and Maximum bitrate up to 62.5Mbps.
Delivery requirements refer to the final export specifications. Film festivals will often post specs for submitted movies (codec, bitrate, resolution, etc). Expect to generate several copies to meet the unique requirements of each festival.

[Steven Sproul] “I don’t know how to get rid of this artifacting, I don’t if has to do with my sequence settings or my export settings.”
The artifacts are banding. What were the export settings, and what are the final delivery requirements? Blu-rays are encoded at 30-35Mbps, and 20-24Mbps will produce very good results for 24-30fps footage using High Profile @ Level 4.1. Set Maximum bitrate to 1.5-2.0 times the target bitrate, and key frame distance equal to frame rate. In the export panel under the Multiplexer tab set Multiplexer to MP4 and Stream Compatibility to Standard.

I don’t think you can recover jobs midstream regardless of whether you are using a subscription or stand-alone copy of the software. Another option would be to render a master copy to a DPX image sequence; if there is a problem you can submit a new job after the last good frame. In addition, consider investing in an UPS or power conditioner.
