Would you like US HDTVs to support 50Hz content/sources (ie. content shot at 25p, 50i, or 50p) as well as the sources they already support?

There is no reason to.

So you would never buy a European-produced drama, documentary, concert or film that was produced at this rate? Like Planet Earth, Pride & Prejudice or any concert or other show or sports disc that was produced in Europe at 25p, 50i or 50p? Or would you never want to watch the bonus content such as making of's for a title on a Blu-ray disc that is at or was originally produced at 25p, 50i or 50p?

BLU-RAY uses 1080p/24 worldwide for 99% of all movies (Bonus features are sometimes in NTSC or PAL). Watching 1080I HD at 50HZ, 720P HD at 50HZ , 576p at 50HZ, and 576i at 50HZ is ideal for international movies and videos that are available in that format. Almost all high-end ceiling mounted Front Projectors support 50HZ HD and 50HZ PAL/SECAM. The discontinued Pioneer PRO-141FD and PRO-101FD supports all the above listed signal formats.

Technically multi region DVD players and BLU-RAY players do not suppose to exist for legal reasons but they do show up on EBAY and other websites. Being able to play a BLU-RAY or DVD from anywhere in the world is attractive to many movie collectors.


The best quality option is for all the studios to encode all the film stocks with 4K or 6K+ masters and then transfer them to 1080P/24 BLU-RAY using high bit rate MPEG-4/AVC or high bit rate VC-1. It will take decades for all the movies out there to be released on BLU-RAY if every. I still have Laserdisc movies that have not come out on DVD or BLU-RAY yet.

What about things shot at things other than 24p? Including all European TV dramas? and all other things I mentioned? Or the US films and documentaries shot at things like 30p? It can't be the best quality for them to be transferred at 24p. Also think about what will happen in the future with 3D and digital cinema.

Film is shot at 24fps most of the time. It is rare to have film shot at 30fps. Now TV dramas and concerts that are encoded at 1080I video at 30fps onto videotape of course are better left in the original 30fps format. When I mention 1080p/24 I mean all film based sources that were shot on 16mm, 35mm, and 70mm film at 24fps.

[HDTV1080P]

Some European TV dramas are shot on film at 24fps, the videotape based PAL 50HZ dramas should be shown in their native format.

For example Doctor Who has been running for decades. It is my understanding that many Doctor Who episodes were shot on film. Some Doctor Who episodes were placed on PAL videotape. Currently the 4:3 film based Doctor Who episodes from the 60's,70's. and 80's are being released on PAL and NTSC DVD from the 24fps film source. In the future hopefully Doctor Who fans will have the film based episodes released in 1080p/24 with the original 4:3 ratio.

I think most of the European TV dramas that are shot on film are shot at 25fps not 24fps. Any film footage of the Doctor Who TV series will have been shot at 25fps. I would have thought any part of the Doctor Who series shot inside a studio would have been shot on video, it's just the outside shots that were probably shot on film in those days.

Your correct there is some 25fps film systems that were designed for European PAL TV transfers. Both 24fps and 25fps films can be transfered to PAL. There is a few TV commercials in the US that are shot at 30fps on film but that is not normal since it costs more money with more film stock used. Shooting TV programs at 30fps for NTSC and 25fps for PAL would be ideal since repeating the frames twice would equal 60HZ or 50HZ with no pulldown judder issues compared to transferring 24fps to 60HZ or 50HZ.

Everything is very complicated. Perhaps a future European BLU-RAY player will support 1080p/25 for TV productions that were filmed at 25fps. Then a 100HZ TV could do a 4:4 pulldown for 1080p/25 material. As far as I am aware there is no 1080p/25 BLU-RAY discs available yet. Depending on the film stock quality, film can handle up to 8K+ quality (planetarium digital projectors can do up to 16K quality). For the best quality film transfer to video a 4K, 6K, or 8K+ digital master scan should be performed. Then the 4K-8K+ digital master could be down converted to 1080p/24 or 1080p/25 for the best possible quality for BLU-RAY home video release.

Well there are 1080i50 Blu-ray titles (just like there are 1080i60 titles) and 1080p25 can be encoded in 1080i50 (just like the Nine Inch Nails disc, which they say was shot at 1080p30 was encoded in 1080i60).

Though it would be better if Blu-ray supported 1080p25 and 1080p30 directly, as well as 1080p50 and 1080p60.

It's easier to find a player that converts, than a display.
