Default Synthesising camera 'look'

Although the Aurora and other system converters do a wonderful job in providing picture sources for old sets, sometimes the picture doesn't look quite right. I put some of this down to the high resolution of modern cameras, lack of tube smear and halos like the old IO cameras gave when looking at bright lights, and different chromatic representation in the grey scale produced (sort of like the diffenece between orthochromatic and pan chromatic b&W film)

How feasible would a DSP video signal conditioner be? I know you can get some effects like grainy scratchy film for video editing software, so could we get maybe a 'plumbicon' effect or 'Photicon' one?

Probably a lot of work, but it would add the final touch to authenticity!

Any thoughts?

Hello Andy

There is a chap in Slovenia working on this idea and I have forwarded a link to this post to him, so if he contacts you it will not be too much of a surprise.

I don't feel I could give his email address out without permission.

regards

Digieffects sell video editing effects that might contain something like what you describe, though I don't have experience of using their tools, I have seen some of the products that have used their software, especially "Damage", which can be used to distort, corrupt and skew the input videos, they have other modules to their suite though which may be able to do more...

I did some searching on the internet and came upon a video from someone who has attempted to do just this, although not in real time though.
The raw video was edited in Corel Photopaint 7. converting the video files to AVIs and cutting them into 10 second segments to make it easier to open the files quickly.
Each segment was then desaturated the picture for B&W, adjusting the brightness to 10 and contrast to -50 to emulate with the orthicon tone, and then the "mask unsharp" effect was applied twice, to emphasise the orthicon look. This process was applied frame by frame, to speed it up a macro using the programs recorder was made, and applied to each 10 second segment. After this treatment, the 10 second segments were re-edited back together.

See here to watch the videos - look for Troyvisual arts

Hi, You can get these effects using sony "videocorders". The AV3670CE? I have gives this effect due to the video circuit (all you have to do is switch the camera to B&W or else it gives you a colour image in orthicon style). The other thing is, you can record video tape with this style too (although mine isn't yet repaired properly so that is the next task I shall be conquering!)
some of them are a little indulgent on the price but I think that they are an investment!

Not sure the effect is exactly "orthicon" style... and because the machine only record every other field, the pictures tend to flicker.
You certainly don't get that negative "halo" effect around bright objects...
