Netflix Streaming Jitter - Page 6

post #151 of 155
What to know what shows have bad jitter. Try Amazing Stories and Miami Vice. They give me a headache watching it.

Seems like very strange stuff is going on (something like frames going back and forward fast). In recent shows and films its not that bad, but still too noticeable. Its simply not smooth. The effect is not seen on dvd/blu-ray releases. Is Netflix aware of this topic?

In their "Encoding for streaming" blog entry (posted November 2008), Netflix mentions this:
Quote:
One class of sources has been derived from 24fps film, interlaced to i60 for TV broadcast, and then decimated to p30, and comes with restrictions on reprocessing. This results in frames that are even-odd interlaces of adjacent film frames, and a 4/5 cadence motion jerkiness. We are actively working to re-acquire these sources in better form.

I notice that both Frasier and ST: TNG are 30 fps (most stuff is 24 fps). Maybe their sources were like that and they couldn't get any better.

^^Which begs the question, why they can't simply pull a dvd off the shelf and create a judder free encode in the first place?

I'd imagine that they have to use the source given them by the content providers and encode them with whatever restrictions they stipulate.

Played arround a bit with the apple tv output setting icm the walking dead ep 1. It does make a difference if I select 1080p 50hz. Its smoother but still a bit jumpy but not like tick tick tick. More like tick......tick. I prefer it to 1080p 60hz. Rather stupid issue...
