I updated my Graphics Card drivers yesterday. I don't think I've ever actually done that before, since you have to go through their official website to get them.
With the new drivers, everything works perfectly now. My hardware is exactly as I described in my previous posts.
If my source is 720p in H.264, I just convert it to H.265 at that same resolution.
Or if the source is 1080p, I move it to H.265 at the same resolution; basically, all my content ends up encoded in H.265.
When dealing with 4K, I downscale it to 1080p in H.265. The reason I don't stick with 4K is that some people struggle even with 1080p due to slow internet, so 4K would just cause unnecessary headaches and issues.
I just tested out Handbrake, and these are the results shown in the image below.
To process a 3-hour video, it takes 18 hours at 720p H.265.

That same video now takes an incredible 15 minutes when processed in 720p H.265.

For a 1080p H.264 source being converted to 1080p H.265, it takes about 17 minutes for a 2-hour and 15-minute file, which is unbelievably good compared to how it used to be.
To me, this feels like science fiction.

My main issue is that I have to run the process twice—once to add logos and text, and again to merge about 10 to 15 files together to reach a total of 24 hours of video.
I am satisfied now, and I don't see any need to upgrade my hardware if things stay like this.
During encoding, I monitored the CPU usage, and it sits around 70%.
Meanwhile, using Adobe Premiere Elements for 24.5 hours of footage takes nearly 6 hours.
