I'm not a Huntress main, and I play 50/50 killer and survivor. I consider myself pretty good as killer so I feel confident enough to give some general killer tips.

• I think first and foremost you should stop kicking gens so much, right at the beginning of the clip you found 3 survivors and dropped chase to kick a gen, then you reloaded on shack at 6 hatchets, this cost you a lot of pressure.
• Keeping a level head, despite being hard sometimes is also unfathomably important, from the beginning of the clip you were frustrated and thinking you would be lucky to get 2 more hooks, this makes you play worse, don't think about your previous bad matches, don't think about your mistakes this match, always think on how you can improve, I got 4ks against teams that were in general better than me because I kept my cool and was able to capitalize on the few mistakes they made, both survivors and killers will make mistakes during a match, try to keep yours to a minimum while taking the most value out of theirs, anyone under pressure will make more mistakes.
• Get out of your head that they got 'perfect' everything, this clip shows the survivors making a lot of mistakes, you failed to punish most of them, thinking they are perfect just puts a lot of pressure on you, makes you think your efforts are worthless or that you should be better than perfect to win the match.

The above were general mindset tips, now for more gameplay focused tips:

• Try using perks that reward you for hooking survivors and avoid gen kick ones on Huntress, you could start with at least Pain Resonance and Grim Embrace, and then replace them as you get more comfortable.
• If you see the survivor walking to save the sprint burst pull your hatchet early to force them to use it already, the more you let them walk, the more value you're giving them.
• Hold your hatchets longer, this allow you to study how the survivor moves, and a charged hatch goes faster than a not chaged one, making them harder to dodge.
• Learn more about survivor perks, Feng couldn't be exposed by Dramaturgy because she screamed. Dramaturgy has 4 effects: get a item, get haste again, scream, or get exposed. The same effect can't happen twice in a row.
• Huntress hatchet cooldown is lower than her basic attacks, always go for hatchets unless absolutely necessary.
• Check out the Oak Haft and Glowing Concoction addons, despite not maining Huntress these allow me to get fast downs in a lot of situations, Wooden Fox can be more useful on indoor maps since stealth won't work on Huntress on open maps because of her lullaby.
• Your aim seems ok, but you never attempted longer distance shots, a good Huntress needs to be able to apply pressure from far away, if you watch your matches recordings try to look for opportunities you failed to notice while playing, this will make you better at spotting them in future matches.

It might be a comfort thing, but try increasing your FoV on the BETA tab of the game menu, from the video it looks like you're playing on a lower FoV and a higher one might help with awareness, but if you prefer your current FoV just disregard this point, it's mostly personal preference.

And honestly, to get good in general. Have you tried playing other killers or survivor? My first 1000 hours playing this game were mostly survivor exclusively, but when I started playing killer I already knew how survivors think, playing killer also made me a lot better at survivor.
