Hi Geoff,
Sounds like you’ve got your results, but another great tool is from Motionvfx, called mRotoAI
Check it out for next time

I use it in Motion5, and it works REALLY well

Hey Ben

Fair enough, but we’ve done tests where we’ve build 2 projects – one in AE and one in Motion, and where AE can take 10-20 minutes to export it’s project, Motion takes 10-20 seconds.

Don’t get me wrong, AE is unavoidable, as the industry is built around it, and it’s had virtually no competition for so long. And we use it all the time, but…

Thanks Ben. I’ll give that a good read!

Hey Ben,

Indeed. I don’t really understand the math behind PreMultiplied vs Straight, but why there are 2 ways of doing alphas that are continually in conflict with each other in different software – that’s just silly.

And yes, while Motion seems to have mysterious omissions in it’s quite basic settings (such as being able to choose Premultipled vs…

Having spoken with an online editor, he has assured me that YES AVID can, like After Effects, be told how to interpret a clips alpha channel. This is the answer to my woes, because Motion 5 (annoyingly) seems to have no way to change its default of…

I have now come to the conclusion that it’s all about Straight vs PreMultiplied alpha channels.

Having dropped a Motion 5 ProRes4444/alpha export into After Effects again, but this time investigating the “interpretation” of the alpha – sure enough, AE was…

Hi everyone,

I’m a long time user of Motion 5 for broadcast graphics work. Over the years, I’ve often encountered issues when we’d provide ProRes4444 with alpha channel exports of “overlay” type graphics, to post production houses, for final graphics to be re-assembled onto graded footage in the online.

Often an online editor would tell me… Read more
