Poor quality ProRes 422HQ exports compared to Final Cut 7 - suggestions?

At my workplace I'm looking at using Creative Cloud to replace Final Cut 7, but I'm having a really hard time producing broadcast quality ProRes 422HQ exports using Media Encoder. Detail levels are comparable but large areas of colour (e.g. a blue sky) show noticeable visual noise.

 

Looking closer you can see only 3 or 4 bands of colour with pixelated edges, whereas FCP deals with these gradients in a much more subtle way.

 

Source files are 1080p H264 movs from a Canon 5D and Final Cut exports (even from FCPX) just seem so much better.

 

More worryingly, I've even tried using AME's Animation codec or even Non-Compressed and the results are still quite a bit worse than a Final Cut 7 ProRes 422HQ export (we export from the timeline rather than using Compressor). Some tests I've done exporting to H264 at 12Mbps are also definitely inferior to Final Cut.

 

There aren't that many options to adjust - ticking Maximum Depth and Maximum Render Quality just adds lots of horizontal lines to the final file. Format is Quicktime, Renderer is set to Mercury Playback Engine Software Only.


Am I missing anything obvious or is Media Encoder just not as good? If so how is anyone using it in a broadcast workflow?


Below are some screenshots which I've made black and white and boosted the brightness so it's easier to see, but the pixelisation is noticeable on the normal exported movs and seems to be a definite step-down from FCP7.


This could well be a deal-breaker in terms of using Creative Cloud in the future - which would be very disappointing as the software itself seems great.

Sorry for the long post - any suggestions gratefully accepted!
