One of the main problems for aspiring creators is obtaining graphics and/or music to use in their videos and thumbnails. The new channel does not make money, so content that can be used without fees is usually sought for. This solution can help in the development of the channel that we create for our own use.
Another important issue is that these websites may exclude their liability and not provide any guarantees regarding the resources provided, which may raise some concerns and doubts. Therefore, if we need graphics or music for commercial purposes, and in particular for work being done for our clients, we strongly recommend using proven, paid services, such as Adobe Stock, where our rights to use the content are properly documented.
The main and safe source of music and sound effects for a novice creator on YouTube will of course be the Audio Library, which is available from YouTube Studio, after logging into the website: https://www.youtube.com/audiolibrary
Canva is a service that allows you to easily - also using ready-made, modifiable templates - create graphics, including presentations and interesting thumbnails for use on YouTube platform.
