What does 結構 mean as a sentence starter?

Question

結構、自然の動画とかを 撮っているんですけど そんなに田舎じゃないです

Rough translation: "Even though I shoot nature videos (here), it's not really that much of a countryside."

I assume 結構 here means something like "often". Is this an unusual way to use the word?

My dictionary gives these meanings:

1. good, fine, nice, all right
2. satisfactory, sufficient, agreeable
3. pretty well, quite, rather, tolerably, surprisingly

The meaning 3 is close but none of them really fit.

Answer 1

This 結構 is not unnatural. The third definition seems closest, but when 結構 is used adverbially, it has a meaning of both "rather/unexpectedly" and "often/fairly/well". In other words, it implies the degree/frequency is higher than one might expect. In this case, how about "rather often" or "quite often" as a translation?

According to 明鏡国語辞典 第三版:

結構

三［副］予想した以上であるさま。極端ではないが、かなりの程度であるさま。
「今度の試験は結構いいところまで行くかもしれない」
「輪投げも結構難しいものだ」
「結構席が空いている」

Similar examples:

• 結構おいしかったですよ。
  It was rather delicious! / It tasted better than you think.
• え、結構簡単じゃない？
  Oh, isn't this rather easy?
  _{(But not "Isn't this very easy?")}
