barneyhall - that's interesting & great to hear. In that case I'd imagine PJ must know about the missing episodes & the occasional substandard audio for some of these. Maybe it just hasn't crossed his mind how helpful his AI software could be for these. I don't suppose anyone here knows him personally, but it would be nice if it could be mentioned to him that such audios might be made fresh, new & gleaming with an extra special dusting of his magic restorative powder. He’s a Kiwi. Paging Jon Preddle! Paging Jon Preddle ! |

I remember one of the RT (maybe Steve Roberts) saying that Time Monster had done to it all that could be done to it and "you can't make a silk purse out of a sow's ear" especially the Ep1 telecine sequences. I guess it's similar to the out of phase stuff, we're stuck with what exists. Peter Jackson certainly made a silk purse out of a sow's ear for They Shall Not Grow Oldwww.youtube.com/watch?v=IrabKK9BhdsYes, it's a shame Get Back had too much noise reduction and lost all its grain but gained a smeary mess instead. |

As technology improves, miraculous things can happen. I've said myself in the past that these stories would be pointless being put out on Blu-ray. As technology existed at the time I said it, I was correct. As technology exists today however, well you can see the results.  As technology exists tomorrow? It can boggle the mind with possibilities. It is really amazing how great the film sequences on Genesis of the Daleks, The Mind of Evil, Terror of the Autons, for example, now look on Blu-ray. I would love it one day if technology allowed for those film sequences to look as good as those for which the A/B roll camera negatives still exist ( Earthshock, The Pirate Planet etc.). Is this dream a bridge too far?? That would be good but please don't let near them the person who seems to think all the reds in outside film should be remastered to be hot orange. Peter Davison's coat piping and Borusa's robe should be the same colour as the inside VT shots, not radioactive glowing orange. |

Yep, this sort of thing is called over-restoration. If something was made on film, it has grain. Clean it up a bit, that's OK, but don't overdo it! And things are only made worse by the compression needed to squeeze a couple of hours of TV onto a DVD.

Ah, so that's what BluRay is good for. Otherwise it would be pointless for old shows made in "standard definition" video.

Ah, so that's what BluRay is good for. Otherwise it would be pointless for old shows made in "standard definition" video. All digital video is compression. There is no such thing as 'lossless' video, because a raw, i.e. uncompressed, video stream derived from a 625-line PAL master tape will yield so much data that it would not fit even one episode on a DVD, nor even on a BlueRay disc. You'll likely be familiar with mp4 video. But you should pause and reflect on the fact that mp4 is a codec for compression of the raw video data, to produce a similar appearance but using much less data. And in fact all the (many) fancy codecs used in DVD and Bluray production are designed to throw away data in order to produce an output file which can fit on a DVD disc or a Bluray disc. The technology does not yet exist that can process a 625-line tape and produce an uncompressed file which can then be played by consumer equipment. The level of consumer resistance is quite high, and the demand is for putting a 2 hour movie, equivalent to 4 half hour tv episodes, onto a single disc. Right now, that can only be done by compression of the data, using a codec, which means losing data. Some day, it may be technically possible to produce micro-chips which are fast enough and powerful enough to handle uncompressed video, on a single disc, and at an affordable price (for both the disc and the player). Rather a lot of money is waiting to be made by someone who can solve all those problems! But we're not there yet. |

The Devils's advocate says we might have that by now if consumer video had stayed with tape. Something with the quality of high-band U-Matic, but not much bigger than an audio cassette, analogue from go to whoa. But HDTV threw a spanner in the works. Seriously, if compression is unavoidable, at least it shouldn't be annoyingly obvious.
