And youtube assigns more bitrate for that, as well. So if your original video is 30fps-this effectively frame doubles it (not frame interpolation) to 60fps. But this is just to fake out youtube into thinking a 720p recording is 2K or 4K, so that youtube will put more bitrate on it. and it uses a lightweight Lanczos scaler. That’s like 12 minutes to upscale the 40 second Dark Souls 2 clips I was testing. The quality is amazing, but it encodes at like 2-6 fps on my quad core, for 2K or 4K upscale. Previously, I was using a program which uses a very CPU intensive super resolution scaling algorithm, for upscale. And since you can run video files through OBS-you can effectively upscale them in real time. Seem’s I need an external encoder.Īlso, I came up with a new way to upscale videos for Youtube. I’m also unsure if OBS can even read uncompressed files. I have a budget SSD and large sustained writes are the main glaring weakness of budget SSD. But, you need tons of hard drive space and also TONS of hard drive throughput. It actually isn’t all that intensive on your CPU. With MSI Afterburner, you can do an actual uncompressed dump of your framebuffer. Trying to do something similarly lossless with X.264 would require a bunch of horsepower (example: Mediainfo reports a bitrate of 374 Megabytes per second, on my lossless Dirt 3 clip, made with NVENC). And then run that clip through OBS and try the different encoders on the exact same content. So, you can record a nearly lossless clip of a game. And NVENC is very fast (it uses Cuda during lossless mode), so its useable. Something cool about NVENC in OBS is that it has a preset for a “lossless” mode (remember to set OBS to record in RGB colorspace, before you use it). I will compare the Quicksync on that, very soon! That’s 4 generations older than Kaby Lake. *I just realized I have a laptop with an Ivy Bridge i5. Older versions of Quicksync may not look as good. *remember, I have a Kaby Lake i5 7600K processor. But have a feelling Quicksync will shine there, as well. I’m gonna go on a limb here and say Quicksync, if you have it (sorry AMD) is the best choice for 2-D pixel art games or old games like NES and SNES. Quicksync had perfect color saturation, sharply resolved every pixel, and was able to keep up with motion, with zero artifacts. Even though I had lots of extra motion options turned on for X.264 Once I started attacking and darting around-X.264 had trouble keeping up and resolving all pixels, during such motion. It matched Quicksync’s color saturation and generally looked the same. I really cranked up X.264 with a lot of extra options. Certain edges and corners (such as dialogue boxes) were muddy. And even with NVENC set to 4 b-frames (optimal for a game with relatively low screen movement), it still didn’t resolve every pixel fully. Ok I just tested Momodara IV and Quicksync won, no contest.Ĭolor accuracy and saturation was way better than NVENC.
