Hi Guys,
I need to do a conversion of DVD videos to Blu-ray.
So, please, in this case: What is the best form to do UpScalling?
1- By software? (I was using Vreveal. However, Do you know other good software?)
2- Or by hardware - I'm using an avermedia DarkCrytal HD Capture Pro + DVD LG Recorder RH397H HDMI
Thank you very much!

Why?
Most (though not ALL) DVD-Videos can be incorporated AS-IS into a Blu-ray authoring project, without scaling or reconversion of any kind. And doing so retains the most quality, rather than "upscaling" and requiring a re-encode with a loss in quality.

Please, sorry for my lack of knowledge, but what is AS-IS?
Thank you! -
You really don't want to upscale from your VHS and mini-DV sources to BluRay resolutions. This is not a good idea. If we had to do this, we'd write an AviSynth script to do it, but the final quality will not be very good with any method to do this.
"AS-IS" means "as is" in English or "without change". He means that you can use your DVD video without change in a BluRay project and changing it will probably make everything look worse. BluRay allows standard DVD resolutions of 720x480 and 720x576 so if your DVD uses one of those, you don't have to change it. If you really want to upscale, try 1280x720 as that will be less bad than going to 1920x1080. -
As has been stated, you don't need to upscale most DVD-video in order to put it into Blu-ray format. If you just need one DVD-video converted to Blu-ray, you can use DVDtoBD Express.
If you want to put more than one DVD-video into a Blu-ray, and have a menu to select them, you should try BD Rebuilder. You will need all of the DVD-video folders within a larger folder for this to work in BD Rebuilder.
Neither of these methods will upscale or re-encode the video (provided your output size is within limits of a Blu-ray disc), so you keep the existing visual quality.Last edited by Kerry56; 8th Sep 2014 at 11:07.

What do you think about this upscaling video? There are others examples on youtube showing similar results.

You must be joking. That UTube demo simply compares poor sources with more modern ones. It demonstrates little more than results that should be obvious to anyone who hasn't been living under a rock for the past 20 years. It has nothing to do with upscaling, except to demonstrate that upscaling smaller-frame, lower-quality sources produces poor results.Originally Posted by NLP

if you upscale , you make things bigger, you cannot invent details in it, if it was not there in the first place
when they make BD's they take their scans and they resize it to HD resolution and that gives them more detail in movie, because there was more detail on film (or resolution if it was shot on 2k digital camera) and then following scan, either 2k or 4k or whatever they used to do or do now, and early DVD's had even smaller resolution from the beginning -
If you sit through the whole video you will notice that it talks about the difference between scanning a film to DVD resolution and scanning it to BD resolution and encoding accordingly.Originally Posted by NLP
They are not taking a VHS source and upscaling it to BD resolution.
As an example, assume you have a movie shot on 35mm film, 35mm film is scanned for release on DVD at either 1080 or 2000 lines as of 2005. I'm fairly certain this same scan is also used for Blu-Ray production. However, 35mm film has the equivalent of about 6k resolution, which is 6144 x 3160, so if one where to scan a 35 mm film at 1080 lines and produce a DVD or BD and one were to scan a 35mm film at full 6k and produce a DVD or BD, then the 6k sourced DVD or BD would look significantly better than the 1080 or 2000 line sourced DVD or BD.
In other words the video you linked to shows the difference between starting out with a given source and producing a DVD vs BD, not the benefits of upscaling DVD to BD.
Additionally, as was pointed out in the comments section of that video, if you are starting out with something shot on DV video there will be no benefit to the higher resolution, likewise a poor transfer will negate any benefits also.
