I use 4kdownloader to download videos from Youtube. 4kdownloader offers videos in mp4 & mkv. I mostly download 720p to watch on my full HD TV as the size & quality is good. mkv videos size is smaller compared to mp4 provided by 4kdownloader. But mkv by 4kdownloader doesn't plays on my TV as 720p mkv encodes comes with VP9 & VP9 is not supported by my TV. So I have 2 options. Download 480p mp4 or download mkv 720p & re-encode it with Vidcoder. (This will take time but its fine with me. As I mentioned above mkv videos size is smaller & thats good for my limited internet plan.) So I want to know which one would look better on my full HD TV, 480p mp4 or 720p mkv re-encoded with Vidcoder?
