I have some movies, some videos, etc that are quite old and poor picture quality, some videos recorded on my Samsung NX1 in UHD but with a stereo soundtrack, along with everything in between. I've been using just about every Cyberlink product for years, but it's always been for small things, like converting a video into a smaller size so the kids can watch something on their iPad while traveling.

After updating to the latest version of everything, it looks like all the software can be converted into a 4K UHD file. Obviously, if the native video was shot in 640x480, and I ran the video through PowerDirector with default settings, the output quality probably won't even be close to native UHD video. With all the new features I've seen being added over the last few updates, is it possible to convert a lower resolution video to something closer to a 4K UHD video using some of your proprietary enhancements, like TrueTheater HD video enhancements and some of the other tools found in the Fix/Enhance section of PowerDirector, or using PowerDirector along with AudioDirector and ColorDirector?

Also, same scenario, is it possible for me to take one of my UHD videos that I've recorded with a stereo soundtrack, and run it through AudioDirector increasing the number of audio channels in the video? I have a Dolby Atmos 7.2.4 system, and I was curious to know if a video, recorded with 2 channels, could be converted into a video with more channels? I realize whenever it's time convert your video, it gives you the option for audio channels, but I'm not exactly sure if, or how, that works. Can a 2 channel stereo soundtrack in a movie be converted to a multichannel audio soundtrack or even be converted into an object based audio format, maybe with a plug-in or something?

If any of these are possible, to increase the video and/or audio quality of a video, is it something that can be done automatically using a wizard or would someone need to make these changes manually, especially with the object based audio formats?

I have a 4K UHD HDR TV in addition to my Atmos/DTS:X setup, so I'm just trying to figure out if there's an easy way to increase the quality of videos to take advantage of the higher quality video/audio? Thanks!
