MPEG Suspected In Lip Sync Errors
Deborah D. McAdams writes in in the March issue of Television Broadcast:
"Lip sync is notoriously bad in digital broadcast television, making a lot of content resemble the original English-dubbed Godzilla films...."
Interesting is the information appearing in the print but not the on-line version of the article: "...Others [individuals knowledgeable about the issue] point out that splitting audio and video from the get-go...was a bad idea in the first place."
No, really? Embed that audio ! That's my motto. I've seen too many 'engineers' running around like chickens without a head (sorry, poor choice of imagery) because they were sending analog audio through the plant with their HD-SDI video and wondering why it was out of sync.
