1992-10-19 Paris Master Video 8

This. Unless the master is taken from an actual professional film camera (not a consumer level handy cam with a video tape) there simply isn't enough data to upscale. There is no real way to upscale an existing video to high-definition, since the information that would be required just doesn’t exist. All you end up doing is making a file that is 3 times the size of what it really should be & duping people into thinking it is a high definition video. It simply is not anything of the sort. It's the equivalent of converting an mp3 into a wav & passing it off as lossless.
An HD video can ONLY be made from an HD recording. If you do any upscaling at all with old video tapes, anything over 720p is a total waste of time & hard disc space.
In any case, a half decent HDTV will make a good fist of upscaling anyway & will do so to optimise for the display itself & not what someone else thought it ought to be like. What software like Instant HD does is add its own pixels according to how it thinks it should look & then faff about with smoothing etc. This effectively results in something that is not true to the master. Bottom line is that the software is just file bloating junk.
As for audio, preserving the raw PCM audio would mean that you wouldn't need to compress it at all. However, multiple audio tracks may all fit on a dual layer disc.

Frankly there is no point making a blu ray for the reasons I pointed out earlier. But like GOD said. It's your project. Just please make sure you warn people that may be under the mistaken impression it's a HD recording that it isn't.
Also, why would you make a 2-3 disc DVD version? If the regular DVD version is 8Gb then use a dual layer disc (8.5Gb capacity)

Sorry to go on a bit of a tech ramble there. This section is supposed to be for requests & trades & the like. So I will just wave an "OFF TOPIC" flag in my own face

Haha.
To hot to bake today. Maybe tomorrow

Just felt it needed saying that a bit of manipulations (cleaning the video, tracking adjust etc.) is about all you can really do to a 22 year old video cassette.
The only really useful aspect of additional software is adjusting the aspect ratio (to be wide screen friendly) & editing/ remuxing audio tracks.
Adding pixels is nothing more than photoshopping really & cons people into thinking there is an HD image.
& then offering it as a download after bloating it up so wildly is going to simply eat peoples' bandwidth & not everyone has unlimited broadband at mad speeds.
The only reason old movies get re-issued as blu rays with stunning results, is that the original (professional) film was used. Before HD tech, even those movies needed compressing to fit onto DVDs. But they were never originally filmed with a device designed for people to make home videos.
