Nvidia X265 Encoder

X265 is a h 265 hevc video encoder application library designed to encode video or images into an h 265 hevc encoded bitstream.

Nvidia x265 encoder. The cpu will still be used for. For bluray i always recommend people just try encoding a brief clip try picking one that has some action movement camera panning as those are going to be the challenging sections for the encoder. Other encoders such as x264 use your cpu to encode which takes resources away from other programs such as your game. Nvenc is nvidia s encoder.

And it is now potentially better than x264 in a lot of ways. It shouldn t take long to encode either way and can help you get an idea of if the results are acceptable to you. Requirements x265 mkv output of course gpu hardware acceleration nvidia cuda constant quality variable bit rate settings. It s a physical section of our gpus that is dedicated to encoding only.

I m trying to find the best video converter for transcoding video to x265. X264 which is better now. Traditionally handbrake adopts x265 as the hevc encoder for hevc and hevc 10 bit 12 bit to achieve an efficient encoding process. This means that your gpu can operate normally regardless of whether you use this region to stream or record.

Handbrake also has different presets between the cpu x265 and gpu nvenc h 265 encoders. Encode using the nvidia gpu took 10 minutes to re encode an equivalent quality 1080p 3 gb x265. On the rtx cards like the rtx 2080 ti nvidia has improved its encoder. These operations all happen in parallel as the job progresses.

Do like 60 seconds or 5 minutes. But if your computer doesn t have nvidia graphic cards x265 will be the only selection. X265 project goals x265 demonstrates best overall hevc encoding efficiency in moscow state university s codec comparison. Star wars force awakens 2hr 18min 21 gb bdrip original 3 1 hours to re encode as x265 via cpu 1 hours to re encode an equivalent quality 1080p x265 using the nvidia gpu 3 75 hours to re encode as x265 via cpu 1 8 hours to re encode an equivalent quality 1080p x265 using the nvidia gpu.

When i use average bitrate of 4000 rather than constant quality at rf 20 i get similar size and quality to cpu x265 encoding. Hevc h 265 is the first codec efficient enough for the high quality hd video portion of the video audio composite file to be smaller than an accompanying 484 kbps 5 1 audio track. Handbrake supports the nvidia nvenc nvenc encoder but does not support the nvdec decoder. 1080p movie x265 hevc encode time.

Either of the encoders can be enabled. From this perspective you can t really make an apples to apples comparison for the quality to file size comparison.
