There are quite a few concert BDs that are SD video.

SD upconverted, or straight SD? Any examples?

Yeah, I'm not aware of any. Examples?

Don't know if they are up converted or not.
Off the top of my head: several of The Rolling Stones From The Vault concerts and The Who Live at Shea Stadium.
They're designated as SBDs.

The Who Live at Shea Stadium is an upconvert, and maybe slightly cropped:
http://www.blu-ray.com/movies/The-Wh...130521/#Review

The Who Live at Shea Stadium is presented on Blu-ray courtesy of Eagle Vision, an imprint of Eagle Rock Enterprises, with an AVC encoded 1080i transfer in 1.40:1. Though it may be masked slightly by the blue of the flag on the cover art, this is in fact one of Eagle Rock's so- called SD Blu-rays, an upconvert from (in this case at least) some inherently problematic standard definition video sources....

No such problems attend either of the tracks featured on this Blu-ray, a lossless DTS-HD Master Audio 5.1 surround track and an uncompressed LPCM 2.0 stereo offering.
I think the main appeal of the Blu-rays of a videorecorded concert is the lossless audio, but Eagle Vision did at least upconvert the SD video.

Not sure if I like the idea of these SD-to BD releases. I'm sure they're all just straight SD 480i, non-upcoverted. If they were upconverted, they'd look even worse due to abysmal compression and video bitrates. I think this is a new level of shovel-ware. 25 movies on 1 BD50??!! 52 episodes on 1 BD?

That's less than 2 GB per movie and less than 1 GB per episode. With such bit-starved content, I'd imagine the PQ can't be very good, in fact WORSE than the DVD-counterparts. Full of artifacts, macroblocking, smearing, etc.

5 GB per move is acceptable for 480i, MPEG2 content, 7-8 GB per move is better yet. That's 4-5x the bitrates that the above releases are exhibiting!

Even steven quality would be ok. If a DVD-9 has 4 episodes of a 1 hour show, 20 episodes would fit on a BD-50 at same quality. Since there would be a few episodes left over, just split the season with 12-13 episodes per disc.

Re: Blu-rays for SD capacity?
 
Yeah, if the complaint is about space, then it's not so much about "SD on BD" but "SD on 1 BD".

I think we can all agree that the "25 films in one" sets are a bad idea.

However, for Samurai Pizza cats, all 52 episodes were originally released as a 8 DVD set, meaning 6-7 22 minute episodes per DVD. The comparison here puts the DVD at a little under 1GB per episode.
http://forum.blu-ray.com/showthread....5#post12730075

The SD-BD uses AVC codec over MPEG2, so the more efficient compression balances out the slightly reduced space per episode. So in this particular instance, fitting them all onto a single BD didn't really compromise quality over the DVD release.


But yes, splitting content over multiple BDs would allow for quality comparable or better than DVD while still using fewer discs.

is there a point in upconverting 480i content on the disc itself? Won't the blu-ray player or DVD automatically upconvert?

There's the possibility that a professional pre-rendered upconversion on a Blu-ray could be better than the real-time upconversion a Blu-ray plater does, especially since the quality of the scaler varies between players. It may not be worth the increase in bitrate storing it in HD though.

This looks to be another SD release (actually two) on Blu-ray: the 1955 and 56 kinescopes of live performances of Peter Pan with Mary Martin.

https://www.dvdtalk.com/reviews/7013...pan-1955-1956/

Since it's film it could be HD (?), but since it's made from non HD video, is there any point in putting it on Blu-ray? Maybe someday they'll artificially add additional lines of resolution.

BD discs can do things DVD can't. It may be worth releasing SD content to take advantage of interactive features.

I don't think anyone cares about interactive features. It certainly didn't matter much to DVD when it was advertised as a "special feature".

A little rich for my blood, but at least they have the sense to have english subtitles on all 152 episodes.

I've love to have more Shin-Chan episodes, even if they're just subbed. This seems like a perfect format for releasing them.

I believe both Pixies' Blu-rays are from SD sources.

The Blu-ray does at least have both peformances on one disc; the DVD releases are separate.

I can't find any resolution info on this disc, but it's very possible it's an HD transfer of a film that's a recording of an SD broadcast.

This review states that they're both 1080i on the disc:
http://bluray.highdefdigest.com/3816/pixies_live.html
[quote]Both sets are presented with a 1080i/MPEG-4 encoded transfer at an aspect ratio of 1.78:1. [quote]

So they may be from SD sources, but they're not stored as SD on the Blu-ray, like some of the extras are. So they're at least SD upconversions.

Jesus, how much porn does someone need in one sitting?! Bunch of damn show-offs, I suppose.
