AYC

AYC or Advanced Youtube Client is a youtube-dl based tool that provides a vast array of batch commands for grabbing videos from YouTube. Similarly to its more notorious alternative, the utility can be compiled into other applications.

The tool is a command utility so it does not have an interface, but rather you can open it with Command Line or PowerShell. The application comes with an abundance of options, so it is highly recommended to open the Help menu and check out all the things it can do.

As far as the downloading is concerned, the tool can grab single videos or full playlists just as easily. In fact, you can pause and resume the operation whenever without too many complications. Videos can be grabbed in AV1 with HDR, 1440p and VP8 or above resolutions and you can download in any available quality, from 360p to 8k. It supports batch downloading and the files can be saved with cover arts, so you can find them easier.

In case you are downloading documentaries for instance, then you may want to grab the subtitles as well. Thanks to the tool, you can automatically generate a subtitle file in the language of your choice and save it as SRT or ASS/SRT/BEST.

The app also includes some noteworthy post-processing options that enable you to extract audio, enhance sound quality, recode video, add the subtitles and metadata or automatically correct known faults in the file, just to name a few.

In the eventuality that you are looking for a lightweight tool to help you download videos from YouTube in batch, but without putting too much strain on your computer's resources, then perhaps you can consider giving AYC a try.
