The resources for accounts is determined by the HIVE POWER of the account. You have only 3 HP. This gives you the resources to post only 5 posts in a 5 day period. They put this limit to stop people from creating spam accounts.
It looks like you have an intriguing youtube channel showing videos with professional quality videography.
A problem you face is that the people on HIVE know nothing about you and your relationship with the videos.
Your account might benefit with a post that uses the tag #introduceyourself . The post might talk about about the general theme of your youtube channel.
Many of the users on HIVE have a poor view of Youtube. You might consider uploading videos for dtube or threespeak ... which are blockchain based alternatives to Youtube.
Good luck on HIVE. the resource bar on hiveblocks says that you currently are low on resource credits. A good introductory post is likely to give you the resources to expand your account.
