That depends on what you mean by 'own music' and the intended audience for your videos.
If the 'audience' is yourself then, in theory, you can use any music you have purchased, providing you have not broken any Digital Rights Management such as may be applied to some music sources such as iTunes.
If the video is for a 'public' audience eg uploaded to Youtube or other publc websites, then:
If you scored and created the music by playing the instruments or using a program and playing VST instruments yourself then there is no limitation. Soundloops used in music creation software may require a Commercial Licence.
If the music is from a third party or commercially available, it is usually Copyrighted, and should not use it without permission from the Copyright owner, this may not be the musician(s) who created and/or performed it commercially. Use without permission risks action being taken, this could range from a 'Take down' notice up to legal action against you.
