Question about encoding
Lupin:
--- Quote from: GadgetAddict on July 27, 2011, 06:47:07 AM ---I rip/backup my own blu-rays pretty frequently and I do know from my own experience that animated/non-live action material handles compression very very well. I definitely think that if they changed their ways from encoding with 16 reference frames to the typical 4 for 1080p, there would be no real drawbacks that would be discernible. What is the best way to contact these fansubbers/encoders? I'd like to maybe chat with them if at all possible :)

I doubt you can convince them. More reference frames help in the compression especially in animated sources.

There would be no drawbacks apart from increased filesize.

Those are stats from a recent 720p encode I made of My Neighbours the Yamadas. It’s a rather low-motion slice-of-life that benefits greatly from increased ref frames. This is encoded at L4.1 so --ref is limited to 9, but you can see that all 9 reference frames are pretty well-used. The number of times 4 or fewer reference frames were used is slightly over 30%.
Most HD encoders have hardware to throw at their encodes, and will happily do so. If you’re looking for L4.1-friendly encodes, seek out groups like OZC and convince them to encode stuff you want to watch :)

Interesting. So basically, you're saying that these encoders typically only view their material either straight from PC or perhaps a HTPC? I know I'm part of a small minority that likes to burn my stuff to disc, but I'm sure the ref. frame thing would eliminate people with those media players like the WD box...Appreciate the information on their "perspective" on encoding :)

Also, the reason I burn my stuff to disc, is because I can easily take my library with me and view things with friends without any fuss. Also, I like having a nice shelf filled with Blu-Ray cases (I even create the box art)...

Most hardware players (if not all) cannot play some of the things fansub groups use in their releases (ASS typesetting). To me, playback compatibility limits what groups can do to make better releases. Of course, groups can have hardsubbed typsetting but this is a slowly fading practice.
