anyone else notice during mp4 playback, audio track half second ahead of video? tried same file on ps3 , totally fine. video in question h.264 encoded standard aac stereo audio. have tried multiple settings , bit rates same result. appears ios software issue. wonder if apple knows it.
m4v itunes store appear unaffected, @ least in standard def. i'm attempting convert mp4 m4v see if helps. in meantime, come on 5.11
av out of sync ipad2 too
have noticed exact phenomenon today- audio , video out of sync ~ 0.25-0.5s on ipad2, playing mp4 h.264 aac. occurs both hd , sd encodes downloaded directly video on vimeo.com. wondered whether video editing team had encoded video out of sync, played same file in quicktime , wmp on laptop without sync issue. interestingly, same video when played directly on vimeo.com shows same behavior- plays out of sync on website accessed ipad, in sync when accessed via laptop. ever hear apple users how amazing apple handles video- not appear case in instance.
