Startup: not bad for a casual video blogger but the bandwidth won’t be enough for frequent video bloggers (3,000 views/month - 3 minute high quality videos).
Basic: not for beginners but not for advanced users either. It’s one of those middle of the road plans for video bloggers (12,000 views/month).
Plus: should be enough for fairly advanced video bloggers. There is enough bandwidth and space to host a fairly popular video blog (60,000 views/month).
Enterprise: the most serious plan for business video bloggers.. It’s not cheap, but for a popular blogger, it is probably affordable (240,000 views/month).
