It's a bit old post but hope you can help me with movie formats.
I'm using Adobe Animate CC and the only export format is quick time. 5 seconds of animation about 170 MB. I'm reading here the best format for playing video in Visionaire is MKV VP8 but maybe this is outdated and now other formats are compatible...
I've found Cloud converter online, you can convert almost in any format. I've choosen WebM which should be MKV VP8 encoding. The incredible thing is that quality is almost the same and it is a 350 KB file!
Also if I want to add something of After effects for logo intro maybe, also here I go for this MKV VP8 encoding?
