Google's YouTube has announced some improvements for videographers and others posting clips on the site.
The YouTube Audio Library is making available 150 royalty-free instrumental music tracks to use with videos (or for any other creative purpose). The service allows users to search by mood, genre, instruments and length.
YouTube's also making some new features available for those using comments. Moderators can allow comments that fans care about to float to the top of comment lists. They can also allow automatic blocking of unwelcome voices and inappropriate keywords.
