Anyone notice the day for night shots in this episode seem really full daylight on this film print? There is no darkening of the scenes as in the DVD versions. It appears this telecine of the negative film is as it was actually filmed, with scene darkening used in later post production to make the positive transmission prints. The bright daylight is very clear, different to any other version I have seen.
I suggest these broadcasts are from early negatives, note lack of cue marks on the film, dust and scratches appearing as white not black, and very obvious scene change visual imperfections, if you play it back frame by frame. The dvd versions are very clearly taken from a different set of prints entirely. Quite fascinating
This is really fascinating. I do recall being somewhat taken aback at the quality of the DVD transfers of the second series. I imagined that the original episodes were made without any grading and (on occasions) without any evident lighting - such was the production's rush to complete the series. The sound too at times was really bad - again, I presume that no one in 1970 thought anyone would be paying that much attention 50 years on! The care and attention given to the first series was evidently lacking the following year and it would seem that some of the faults in the filming would be impossible to fix without heaps of finance. I haven't seen many of the TPTV broadcasts but what I have seen the quality is pretty ropy. Mind you, if it does encourage people to buy the series on DVD, that can't be a bad thing!
The Black Wheels episode on Sunday was a really truly dreadful print, noticeably going out of frame briefly at one point,and more scratchy hiss on the audio than a worn out vinyl record. But at least TPTV are not showing the prints with the break bumpers hacked out which were last used by itv broadcasts.
