There is a lot to like about this video. Beautiful countryside. Very nice.
But as you have put this in the "critique" area, I would assume you want constructive comments to help improve. This is a good film and very good "first" documentary. I think it has more potential with the footage you've already done. I have only a few suggestions. Forgive me for being critical. I offer these suggestions with the utmost respect.
1) Even with the most compelling videos the human can only deal with 3-5 minutes, and 5 minutes is pushing it unless they have a specific interest in the subject matter or it is so unique and breathtaking that they are compelled to stay with it. So, my first advice would be to isolate your most compelling shots and remove anything else that isn't breathtaking or has a specific POI relative to the narration. You have plenty of great video there. So much good video gives you an opportunity to cut it down to show only your best, most impactful stuff.
2) Can you bump the resolution to 4k? YouTube is only allows me to pull it up in 1080p. It's something I did too on my first project was assuming that 1080p was good enough
3) You have a beautiful speaking voice, have narrated the words clearly, distinctly and pleasantly. However the acoustics of the voice-over are extremely poor due to the subtle echo caused by recording in the wrong acoustic environment. The sound needs to be much deader, and if possible EQ'd a bit. What mic and recording system did you use for the voiceover. Be aware of the room acoustic and your position in the room. If you can, try to create a makeshift vocal booth. Sometimes a clothes closet with lots of sound absorbing clothes can be all you need. You don't want to be in a space with hard walls and floors with no sound dampening.
4) My last comment involves color grading. This one is personal taste, so I'm voicing my personal opinion (not like I didn't do that in my above comments
). But if I were your editor I'd bump the color saturation a bit. I think more saturation without overdoing it strikes a chord with most viewers. The scene with the boat has more saturation than most of the other scenes. Perhaps use that as a guide as to how much color the greens should have as do the blues on that water scene. JMO
I think there is a gem of a finished product hidden in your footage. I cannot tell you how many projects I've posted here initially, only to view them a day or so later and think to myself, "What did you post that for... it's ?... And then I'd go do a full reedit on the thing again and turned ? into
.
I hope you find my comments helpful.
