Hello, welcome on the forum! Could you introduce yourself in a new thread there?
https://sora-to-kasai.forums-actifs.com/f1-presentation Thank you!
For your video, I found it interesting, your scene selection is classy, you have some very nice parallels between the animes (0:44 was so badass). Moreover you exploit the song's sounds and you use well your scenes to create both impacts and atmosphere (the phase at 1:34 is a nice example).
But, you don't pay enough attention to the colors, one example among others is at 0:57, we have purple/orange > green > purple with not more than a cut, it needs to be a smoother change.
Also, for a mix, you don't always vary the animes enough, it's not good to have a very long sequence with the same anime and then go all various. The video needs to be more homogeneous. Basically, you used too much of KnK in comparison with all the others
Another problem: your cam moves. They're not accurate enough, for example at 0:20 you should have made a stronger rotation and zoomed higher and deeper to really match the next scene. Be careful with that because it ruined all your zooms.
Then you have this "bounce" trend that breaks the movement of your vid. At 1:41, you dezoom then you zoom again, you should avoid contrary movements on the same scene.
Be careful with the rolls too, they shouldn't be used on close up like at 2:25 because it creates unconsistent edges. Well try using them only if they seem completely justified.
And last but not least, I think I spotted some frames blending/ghost frames (example at 1:06 with Misaka), remember to always have the same fps for both your scenes and the project. If you are on vegas, don't forget to check "disable resample" in the properties of the scenes you accelerate.
Anyways, I'm curious to see what will be your next works, keep it up
