As investors digest the implications of Netflix (NFLX 1.74%) first-quarter results, here's a look at some critical quotes from the earnings call. Often overlooked by investors, the earnings call offers a closer look at important narratives for the company, including how management views its international opportunity, why its guidance for international members was lower than expected, and how Netflix is different from Amazon's Prime Video.

It's going to take time to realize international opportunity
Looking forward to international growth, Netlix CEO Reed Hastings explained that while it has expanded to international markets these new markets will need to be localized before the company can fully tap into these markets' potential.

And remember that most of those [130 countries we expanded to in January], we haven't yet seen the full potential of, because we're only in English and only with international credit cards.

Hastings went on to explain that it's going to take some time to beef up its international offering.

So, over the next couple years, as we further localize, we'll be able to see more opportunity.

Recent international growth wasn't normal
Even after Hastings' note about how early the company is in the process of building up its offering in international markets, analysts continued to field Netflix management about the company's prospects for international growth. It's no surprise this was a common theme throughout the call, as the company's guidance for net international member additions for Q2 was much lower than expected.

The reason for the disconnect between what analysts were expecting Netflix to guide for and the company's actual guidance boils down to tough comparisons due to the company's recent international expansions.

Netflix CFO David Wells said it best:

In terms of thinking about the guide, just a reminder that we put in the letter, that absent the strong performance we saw last year from the very recently launched Australia-New Zealand market, our guide would have been up. So, I think you haven't yet seen sort of a normalized pattern of growth from us as far as a year-on-year growth expectation across our international markets, because we've been layering on new markets as we go. ... [W]e're mindful of the fact that we've got this large bloom of launches last year and then in Q1 this year with the 'Rest of World' markets -- the Netflix global launch -- that aren't going to continue forward because they're addressing pent-up demand.

The company guided for 2 million net member additions in international markets in Q2. This figure was more than a million lower than most analysts' estimates -- and lower than any quarter's international net additions in 2015.

Amazon's stand-alone option for Prime Video service is no surprise
When asked about what Hastings thought of Amazon's decision over the weekend to offer a stand-alone subscription option to Prime Video, Hastings noted the move only highlights the natural evolution to Internet TV that Netflix is so bullish on.

And so we're seeing growth in the overall Internet TV market -- of course that's displacing linear TV. And it's natural that everyone is coming in as they realize that the future is Internet TV. ... Again, this is all part of the natural evolution from linear TV to Internet TV.

How Netflix differs from Amazon's Prime Video
After being asked about what Hastings thought of Amazon's reported talks with programmers to offer linear channels as part of Prime Video, in addition to its Netflix-style offering of originals, on-demand content, older shows, etc., the CEO promptly and succinctly reminded investors exactly what Netflix is aiming to do -- and how it differs.

First, he explained that the company's huge emphasis on original content very much because of its aim to produce as much global content as possible -- whether its global because its simply cross-culturally appealing, in Spanish, or completely localized.

"And that's very different from carrying other people's single-nation networks. So, this is just a very different business."

But after explaining why he strongly supports heavy investment in original content in lieu of reliance on existing programming from linear TV, he boiled Netflix' simplified value proposition into as few words as possible:

"We know what we want to be, which is a great global producer and distributor of content," he explained. "And other people will do other things. And that's fine. They may be very successful."
