Eltens converting is bugged. Sometimes it completely destroyed the video quality or not even saved it properly, or took overly long, but the next time 10 seconds. Dude elten isn't capable enough of that stuff.
Pontes works well but it has problems sometimes. Still though it should be good enough. To be honest, I never used elten to download from youtube, now days I use whether renova music or TCA-MediaDownloader. I have pontes as well so incase if one of them fails to download I use another.
In response to Karl, I either use Elten or used Accessible YouTube Downloader till it died, so I didn't need any URL. Now that Elten is my only source, I'll just have to live with its occasional problems.
Yeah. Whatever people say about renova music it's still faster and better especially because you can choose in which format you want to download the video. You can download as mp3, ogg or wav format I believe, or download it as video. But as you mentioned before, since it is in bgt it has that stupid unicode problem which I think you know. So if I search for something in Arabic it shows these letters as question marks. That's the only problem I have with it now, otherwise it's great.
Hermis, it didn't update automatically. I got a new ytdlp and put it as youtube dl to the youtube folder. because it was making error 20 -- (hermis501): you don't need to rename anything. it goes with included yt-dlp, but for any compatibility issues i keep the same name as youtube-dl.
