Hi Julio , i don’t know if moviemaker can support png+alpha channel mov. files .Sorry for the late answer (we were on vacations).Thanks

Thanks for answering my question!

I am a kindergarten when it comes to editing videos. After Effects is very expensive, so I purchased Filmora Video Editor and I am going to explore it on my July (when school is over and I have more time – I am a teacher). Do you know if it will work with Filmora?

Sorry for disturbing you! Have a great vacation!

Warm regards,

Julio, from Brazil!

Hi Julio, i don’t know Filmora video editor software, but i made a little research and i found this (http://filmora.wondershare.com/tech-spec.html ).I can see that supports .mov files but i did not see anything about png + alpha channel. I think you should contact the support to have clear answer (http://support.wondershare.com). Hope i helped!!
