Afaik, it's still not possible to apply time remapping for the whole clip so that both video and audio parts will be changed simultaneously without making the audio out of sync. It has long been a feature request, I saw the post dated as far as 2009, asking for this to be implemented and the numerous posts after that with the same request, but it seems that all the requests of users were to no avail. So, my question is, why hasn't it still been implemented, if it's so in demand and would be really useful for users? Adobe never intends to listen to users and actually do that? And why to have this feature request thing at all, if the ideas posted there are never actually being implemented in practice?
