Step 3: Choose your targeted video format from the top right corner. There are a lot of formats available. Including MP4, AVI, MKV, and MOV. After this, click on the conversion icon on the right of the chosen file. If you have to convert all the videos in the chosen list, simply choose the “Convert All” option on the bottom right of the main window.
If you mis-tag your videos for the wrong set of audience, the FTC could charge you with compliance issues, and later, even takedown your channel. Other disciplinary actions include the implementation of fines, which could go up to $42,000 for each violation. Even though the help-centre of YouTube claims that they will look into the financial status of the content creator before the fines are decided, it still could add up to a considerable amount. Many YouTube animators are currently in a dilemma, as their work is not directed at children, but cannot be tagged as “for adults” either.
The same as you do to download any other videos. You just need to choose the 1080p or 4k format in the video result section, sometimes it is in the "video only" section that without sound, then you have to download the audio file (M4A) in the same result section, then you can load the video file and audio files together on your computer using the video playing software, such as VLC. You also can combine the video and audio files by using ffmpeg. Some youtube video does not have HD format originally, in such case, you definitely can not download any HD format video.
