I thought I would quote what was written in another thread by another member (with a poorly chosen name) that expresses the frustration of the untested pile of heaping mess that is after effects.
I don't generally post anything anywhere but feel the need to comment on just how inconsistent and unreliable the new 2015 Preview is. Whilst I appreciate there has been a huge under the hood change to the way it works I cannot believe it's been put through the paces in real world testing prior to being released - feels almost like a beta. I appreciate there are updates on their way but should such a key part of the program be so bug ridden to the point of annoyance prior to being released?
Could someone please let me know the reasoning behind the Preview playing back prior to it caching? What is the purpose of that? Am I missing something? How does that in anyway benefit the user? When working on a project with audio I get the audio playing out of sync when as each frame caches - which is incredibly annoying both when in a studio with speakers or with your headphones on. Yes, I can turn this off in the settings so that audio out of sync doesn't play, but that leaves me with no audio on Preview. Also, when things finally do cache and it plays back it's rarely in sync (why?!?!) meaning I'm left with stuttering audio on Preview and steppy single frame of audio whilst caching. How is this in anyway an improvement on how things worked previously?
Sometimes I cache and playback and the cache disappears. Subsequent presses of 0 do nothing at all. Restart of AE seems to solve.
As the poster above mentions things don't seem to stay in sync - multiple previews mean the first one plays back fine then subsequent ones stutter or have to cache again. The whole thing seems almost engineered to annoy the user (of course I know it's not but it is infuriating that an 'upgrade' means well below par performance on a feature that is so integral to working in AE).
And why do I end up pressing 0/any random combo of keys to please for the love of God stop the Preview?!?!?!!
One more annoyance - rendering no longer previews in the composition window. Whilst not a killer feature it DID allow the user to watch the render in the background and thus be able to notice any small issues/mistakes/wrong thing rendering during lengthy renders.Now we have to wait until the entire comp is rendered and then watch back - insane and for me a backward step.
Apologies for the rant. Massive backward step on what should be the most rock solid basic part of the program.
BTW I do LOVE the way we can alter the interface/Project window whilst Previewing which is a welcome bonus. Just wish the playback would get up to speed.
