Ah, cheers John. Here's me thinking that Ayesha had an alias.  |

Video Ark do indeed have an electronic solution for CV2000 tapes. I don't know if this is unique to CV2000 and can be used on other 405 formats but it is a bespoke system. At the moment, they appear to be the only company that can do such transfers. I haven't seen any results though, so I don't know how successful the system they have is, but it does by all accounts work. I may give them a tape to try. Of course, the ultimate aim is to achieve a direct capture regardless of the format and that would require a dedicated capture card for a computer and software, which someone would have to write!

Moderately priced set-top digital standards converters like the Aurora have been available for years, able to convert 405 to 625 and vice versa along with other obsolete standards. 405 line signals can also be recorded onto VHS tape without electronic processing, a convenient way to pass 405 line recordings around if you have a 405 line telly to view them on. The problem here is the possible instability of the recordings. I just want to clarify this in case we get the idea that electronic copies of 405 line recordings can't be made at all.

I was wondering if a standards converted could be made to work, though they are normally 625 to 405 & not the other way.

Sorry Sue, but the Aurora only supports Pal, Secam and NTSC on the input, but can output to 405 line. It can't be used as a stabiliser as it can't accept 405 line on input. You're right, you can copy 405 line material to VHS and in fact U-Matic and in the short term, U-Matic is probably the better solution because you can at least get the material off onto a more stable format. However, what I am interested in is preserving the source content and that can't be done on a VHS or U-Matic tape. The ultimate aim is to create a tapeless capture system that can accept the longer line length of 405, the higher video voltage and, importantly, the unstable playback. Paul |

It would appear that Ronnie's tapes are indeed transferable to DVD. Maybe the quality won't be absolutely 100%, but from an enthusiast's point of view we could at least be able to watch some very rare material. As I said before, I think the real issue is doing a deal which is acceptable to both him and the purchaser, which, judging from all that has been said is looking unlikely.

I've PM'ed Ronnie highlighting the Ayesha Brough interview & the contact at the Express. Always assuming a) Ronnie still looks at the forum, and b) he hasn't already made contact, it still looks his best bet. Perhaps you could mention it to him if you are still in contact? |

The impossible can be done given time, miracles take a little longer !
Any sufficiently advanced technology is indistinguishable from magic !
Considering what's been achieved with Reverse Standards Conversion and Colour Recovery I have a lot of faith in the ability of some very talented people to achieve things.
I'm not sure how much material there is that would benefit from conversion ?

I was under the impression that the Aurora was switchable between standards, but it wasn't. Anyway, I've put the question of electronic conversion of 405 line tapes to the television people on Vintage Radio. |

Crowdfunding anybody ?

Now that could be a good idea John?

How about (someone suggested) building a really fast sampling analogue to digital converter that could save the 405-line waveform as data without attempting a conversion? Conversion could be sorted out later.

Conversion could be sorted out later. Funny you should say that. But there is no 'waveform' to save, but rather the raw analog data, the 377 video lines and the two field sequence. There is a project in the works and it's funded. It would then mean a small cost to transfer a tape, but the R&D costs are high. Paul |
