Is it possible to filter by resolution please?
I have a 4k monitor, and find that after downloading rather large files over number of weeks, that they are impossible to view due to the low resolution of the original file.
I've noted on previous threads that some Globals Moderators have the ability to remaster files to a higher resolution, but I have not as yet learnt this dark art.
There are a few technical points here worth noting:
1) I have found that a video file will look best at the original resolution in which it was created. For example, most standard-resolution DVD material from, say, 2000-2010, was recorded in 480i (640x480). It's possible to use software to increase the dimensions of the video file (such as to 1440x1080), but that's not going to improve the clarity of the image–it just stretches it out. You can't add information that wasn't there to begin with. And, depending on the software used to do this, it might even make the image look worse. We can't make a true high-definition video out of a lower-definition video. Some users on here will take a standard definition video and use software to "stretch" it, and claim that they have a "high definition 1080i video." That's deceptive...and just plain wrong.
2) I, too have a 4K monitor. If I want to watch a video that is smaller than (real) 4K, my computer graphics card and monitor will do a better job of stretching the image out over the screen than a graphics application that fiddles with the file. To put this another way, a non-4K file will look better on your monitor if you leave it as is, and let your computer blow it up to full-screen. (I use VLC player running on Windows.)
3) It's true that there's some good vintage material from the 19080's and 1990's that is low resolution and enjoyable to watch...but it can look wretched on a large screen monitor. Unfortunately, there's no way to fix this. I have some old favourites that I watch occasionally, and find the low video quality more tolerable if I just move back a bit from the screen.
4) If you do want to change the frame size (resolution) of a video, I've found that "Movavi Video Converter" works pretty well, and is easy to use. I got it a few years ago, and I think it was about $75 US. [This is not an advertisement, and I don't own any of their stock.] I use this to join files together, especially when they might have different frame sizes. It's also handy if you need to change the encoding btween .avi, .mp4, .mov, etc.
Happy viewing!
