Nvidia Nvenc Vs X265

On the rtx cards similar to the rtx 2080 ti nvidia has improved its encoder.

Nvidia nvenc vs x265. It wasn t unusable without a doubt yet nvenc used to eat a ton of subtleties. Handbrake also has different presets between the cpu x265 and gpu nvenc h 265 encoders. For streaming or youtube videos. And it was awith my 2080 i tried with.

Comparison nvenc hevc is clearly better than it used to be and may be the best gpu encoder especially if you are using an original source or anime. But it is also clearly inferior to x265. I have a decent grasp of the differences between cpu based encoding such as with x265 vs nvidia s gpu encoder in so much as i ve done numerous encodes of my own and can definitely see the pros cons. And as it s movies for my phone then i rather have a good quality.

But that s old nvenc. On the rtx cards like the rtx 2080 ti nvidia has improved its encoder. Vp9 just one single config to compare to the rest. Nvenc including kepler maxwell pascal and turing series cards.

X265 x264 qsv nvenc vce x265 x264 are cpu software based encodings and quality wise better than gpu based encoders from intel qsv nvidia nvenc and amd vce. This choice infrequently harms execution. X265 the newer h 265 format in several presets. I was using the same settings quality 22 and the audio was aac bitrate 160.

I just realized there s an nvidia nvenc encoding option for some of the codecs with handbrake. Av1 the codec of the foreseeable future. Quicksync in both h 264 and h 265 variants. So i went with x265 on all the movies.

I always go full nvenc with. If it is to make a rank for these cpu and gpu encodings the order should be. From this perspective you can t really make an apples to apples comparison for the quality to file size comparison. X264 which is better.

I use nvenc all the time as a hobby with the same frontend as you do. When i use average bitrate of 4000 rather than constant quality at rf 20 i get similar size and quality to cpu x265 encoding. Best handbrake alternative to encode video with hardware acceleration. I tried nvenc h265 slowest 2mbit vs x265 normal 2mbit and x265 was a bit better in quality.

In any case the issue in the past was that nvenc s quality wasn t practically identical to x264 at 6 mbps or lower. And it is now potentially better than x264 in a lot of ways. I ve tried encoding a video with h 265 with the cpu and nvidia nvenc and it was much faster with nvidia but the file size is also much different.
