Personally, I err on the side of less compression but I store my media on HDDs not SSDs. You could compress a 4.7gb DVD to as small as 700mb or go big and leave it in its original format. At DVD resolutions a modern CPU will be pretty quick at x265 encoding. In terms of what setting to choose, if this is your long term archive, I'd recommend against hardware encoding and stick to libx265. Using 10-bit usually equates to higher quality at the same bitrate, even for 8-bit content without much change in speed. Many people recommend RF21 for DVDs using libx265 which would squish the average DVD to around 1.2gb. I am able to do it using CPU/GPU, however performance is not acceptable, I use the following command line:: ffmpeg -inithwdevice cudahw -filterhw. I am trying to encode 10-bit content to 8-bit, is there a way to this in complete GPU. I.e., some people still swear that x264 is better than x265 to their eyes for their content. Gaming and Visualization Technologies General Topics and Other SDKs. Video compression ratio (bitrate/filesize)Įveryone has different opinions on what setting is best for their use, and you should trial some different RF settings to see what works for you.

The different settings / encoders affect the three corners of the encoding triangle. 50,000 bitrate, then using Xmedia Recode to convert to 10,000 bitrate (for. Nvenc uses Nvidia's hardware accelerated NVENC encoder. Test - porwnanie kompresji x264 8bit vs 10bit, x265, xvid, Jak kompresowa. QSV uses Intel's hardware accelerated Quick Sync encoder.

X265 uses libx265 and is software encoding done on the CPU.
