When composing an animation for YouTube, do we need to consider where our animation is within the Title/Action Safe grid or is that only for TV? If it is also for YouTube, which of the two frames should we keep our animation within?
I might be wrong but I think is mainly for television and maybe film. However you DO want consider visual layout and make things "easy to see". But I don't think you need to worry about this for Youtube, at least not for any technical reason.
