Hi overkill22, & Everyone Else,

If you have a video that you do not mind sharing with us, provide a download link to me and I will create a quick video tutorial on using Kdenlive to "upscale" (increase, enlarge, transcode, etc...) a video from its current lower resolution to a higher resolution. The "rendering" output settings I already provided should work well. Then, you can tell me and the rest of us whether you think the video looks as good or better (improved) than the original.
In my previous reply, I was just suggesting that people who have lower resolution videos (480p or less) that they might consider trying to upscale (enlarge, increase resolution) which will also transcode (convert) them into higher resolution using Kdenlive video editor before archiving them or putting them onto discs.
I know that just "upscaling" videos and images do not normally "improve" the quality and normally can actually reduce the quality. I cannot explain, because I do not know, why the excellent Kdenlive video editor is able to "upscale" (increase, enlarge) and "transcode" video and images as well as it does, but it does
and better than any other video editors that I have tried. Anyone can try it for themselves to see what I mean. If the original video and or images are very low quality and "grainy", then it will probably still be that way when upscaled and transcoded although there are effects that can help with some of that. I did not use any of Kdenlive's "effects" when doing this, I simply selected the project resolution (720 at 29fps), added the video clip, put the clip onto a video timeline, clicked "Render" button and adjusted the rendering options like my screenshot, then clicked render to file button. FYI: Enlarging (upscaling) images is not supposed to work well either, but Gimp v2.9 or v2.10 with the "Resynthesizer" plugins does very well at enlarging (up-scaling) images.
Kdenlive FYI: I always install Kdenlive from the "Synaptic Package Manager (SPM)" with all of its recommended and suggested packages which provides various video and audio support packages (codecs), then I add their PPA for the most current version. They also have an AppImage which I sometimes use which should work an all editions of Linux Mint. Because Kdenlive is a KDE application, for Cinnamon, Mate or Xfce users, I also recommend installing the "kde-runtime" from the Software Manager or Synaptic Package Manager (SPM) which is perfectly safe to do in all editions and versions of Linux Mint . I also install "ffmpeg" version 3.x which is in Linux Mint 19.x "Synaptic Package Manager (SPM)", but requires a different installation method like a PPA for Linux Mint 18.x, then also install "x264", "x265", h264enc, as well. (restart your computer after installing these before using Kdenlive)
