I'm inclined to agree with this. Like you say, increase the price and offer more value: there's a $10 subscription, but how about a $10 one-off, which allows me to create as many videos as I like for the next two weeks, or next month? I'm sure there are probably other - perhaps more interesting/creative - ways you could offer more value if you spent some time thinking about it. Also, offering payment options that don't require me to fill in a form with my credit card details for yet another frigging website. I hate to recommend them in some ways - because they've caused me aggro so many times with transactions larger than a few hundred quid - but PayPal might be a good option here.
