I use Animate and it would be a "feature" if ME would be able to output FLV.
Any roadmap to introduce it?
This feature was removed many versions ago, you can all but guarantee it won't be re-introduced. If you have an old version like CS6 on disk then you should still be able to do this.
So it seems Animate is intentionally broken and unsupported for FLV conversion.
Shame and I guess I will migrate to an alternative.
I don't see how this intentionally breaks Animate, but FLV is a format that's all but dead. May I ask why you still want to use it rather than MP4 for animation or HTML for interactive projects? I understand that FLV had some impressive features that still can't be replicated by the current formats, but the fact is that browsers are disabling Flash player by default now, so the majority of users would never see your files anyway.
