When a porn video that was originally on NTSC DVD is converted to PAL DVD for the UK/European market, should there be a difference in running time between the two?
I know that when feature films are converted to PAL that they are about 5% shorter, but I mean porn films that are originally shot on NTSC video, and (professionally?) converted to PAL.
PAL is 25 frames per second, NTSC is 29,97 fps and regular film is 24 fps. The differences in running time come from speeding up (or slowing down) the tape a little bit to go to the other rate. It also depends on which format the master is in. I am sure one of our resident editors will know the exact details.
When films shot at 24fps are transerfed to PAL, it's down one frame to one frame, and the sound track is sped up by 5%. The resulting PAL version is slightly short, and the audio pitch is slightly higher (Maybe they have a way to do this without changing the pitch now)
When video shot at 29.97fps (commonly refered to as 30fps) is converted to PAL it is done with frame interpolation. 16% of the NTSC frames are dropped to fit into the 25fps PAL frame rate. The imperfect time base relationship (25 vs 29.97) means that there will a ultimate difference of about .02% between the NTSC and PAL. There's also spatial interpolation because PAL and NTSC have different pixel arrays.
I'm not an engineer, so I may have some of the specifics wrong. But the idea is more or less correct.
So if a US Falcon NTSC DVD with a running time of 90 minutes is released in the UK on PAL DVD with a running time of 83 minutes, then something has been cut?

gambrinus- There is a chance the difference you are referring to in the Falcon DVDs is the difference in time between the uncut and retail versions of a specific title. Falcon produces two versions of some of their DVDs. These would be the ones that have fisting or waterspots.
If a title contains either of these, it will be excluded from the retail version. The mail order (or european versions) are only available directly from Falconstudios.com or tlavideo.com inside the us.
So that maybe what accounts for the time difference on the disc.
Thanks ghostpro. Maybe Falcon wasn't the best example, as they release director's cuts. But I was referring their normal releases.
I guess my point is... although the BBFC (who rate R18s) website says that no cuts were made to Falcon's 'The Recruits', it says that the running time is 83 minutes. But the US version is 90 minutes, and 90 minutes is about average for a Falcon movie.
Maybe the version submitted for rating was already watered down by the UK distributor...?
This topic (editing for international releases) has been discussed before.
Basically, the DVD producer edits out content that will most likely be objectionable to the target market. The DVD submitted to the UK censors was already edited; the UK censors are saying that no cuts were made from the version submitted for review.
It's easier for everyone to get it passed the first time around. No re-editing by the producer, no remission/review to the censors, no costly delays for the distributor.

Falcon ALWAYS states on their box art that the running time for the movie is 90 minutes, when most of the time it is shorter. Falcon likes to include trailers in this "feature running time" stat.
The most accurate information I have seen on actual run times is on TLA Video's website. They show the running time for "Recruits" at 85 minutes.
Thanks ghostpro. It was actually The Recruits that I was thinking of. I'd misread the time on the BBFC site as 83 minutes, rather than 85, so the running times are equal. I also had a look at the running times for Taking Flight on the TLA and BBFC sites, and those are equal too.
It's normally only fisting and watersports that the BBFC have a problem with, so I was surprised that an apparent 7 minutes was missing.
And to cv: I'm a newbie here, so will do a search for topics about editing for international releases..
But that's really the TV's that will handle both PAL and NTSC right? The vase majority of DVD players will just pass PAL or NTSC through to the TV with no modification. It's up to the TV to be able to display it correctly. DVD players that will convert PAL to NTSC and vice versa, while they do exist, are far more rare.
Our problem in the US is that, except for some projectors and HDTV's, finding a TV that will display a 50Mhz PAL signal is rare.
I just checked the manuals for my DVD-player, TV and VCR and only the VCR does mention PAL/NTSC at all, saying it will play NTSC tapes on a PAL TV. The DVD player is some cheap brand X and the TV and VCR are from JVC.
Yes, my TV handles NTSC DVDs perfectly well. In fact, since seeing some really awful NTSC to PAL conversions of R18s distributed by Zipper in the UK, I've stuck to buying the NTSC versions when I can.
