Did you use RTX HDR and then screen record? This is a method I didn't think of. However, it is easier to get the effect you want with color grading software. I have graded many videos of this kind. I am glad that someone is doing something similar. Two years ago, I found that converting SDR KPOP to HDR would have a better look. So, I made a plan to reset most of the KPOP MVs. However, as my understanding of HDR deepened, I found that this was a wrong behavior. I kept improving the video to achieve the desired effect. However, this work was too tiring and took me a lot of time. Now, I have to do other things. Although my plan is still going on, it has slowed down significantly. I hope you will not give up on it. There is an obvious problem with your video, which is that you should increase the bitrate. I think it is the screen recording that is limiting you. I think you will be interested in my video, enjoy Aespa - Armageddon.7z Taeyeon - INVU.7z
Well, you're right, but in my case increasing bitrate above the original bitrate of the real MV is really dull, the quality is still the same (also i have to make the file size as smol as possible cause i need to upload as much as possible on a file hoster account XD.) Beside, grading it yourself will take a lot more time, cause brightness are vary from frame to frame, trust me i've done it here and it took me more than 2 hours for it (the link is here: Red Velvet - Chill Kill [4K Apple ProRes, HiRes 24bit/96khz, HDR Remaster] | ShareMania.US) NVIDIA RTX HDR is using AI, so if you want the method, I could share to you how i done it XD
