I know it doesn't comply with that challenge thing, but if you are in a hurry (often the case with a client), you should consider post-work on an editing software. I don't do animation in Vue yet, but watching yours reminds me of similar problems I had with animating still pictures in editing (doing that famous "Ken Burn" effect). Same flicker ! In the soft I use for editing (Final Cut) there's a filter called animation blur. By adjusting settings, I was able to get rid of that flicker with (very) minor loss of quality. I'm sure it's a current function on others softs. Another advantage : no increase in render time. If you are interested and if I have a little time this evening, I will try with both your tests and post the results. Again, I know it's not a "purist" way to do it, but from my experience with clients : anything that does the job
