So if you need to convert videos to any other formats, Handbrake isn’t going to be much good. For further details on how to convert more general media files to other formats, check out this Tech Junkie guide.

Handbrake H.265 Encoding Test, How to Use GPU Acceleration Date January 13, 2017 Author Catherine Category,,, Pre-reading: H.265, aka HEVC, is the successor to H.264. H.265 is meant to double the compression rates of H.264, allowing for the propagation of 4K and 8K content over existing delivery systems. Videos encoded with HEVC will maintain the same high-quality as the equivalent H.264 video, but at a smaller file size. The Most of people who want to will choose to use Handbrake because HandBrake 0.10 and higher version like the latest have been added support for H.265 encoding.
But what about the performance of Handbrake HEVC encoding? Is whether transcoding (converting) your existing h264 video to h265 with Handbrake worth the effort and time? Part 1: H.264 vs H.265: Handbrake Transcoding Comparison Preparation: Experiment Purpose: 1) What real quality difference would come about from transcoding from H.264 to H.265? 2) What size difference would come about from transcoding from H.264 to H.265? 3) Time cost Original Video: 1280×720, 25 fps video, and 1536 kb/s audio and already encoded in H.264. Size and Time Result First, encoding with Handbrake with H.265 versus H.264 took about four times as long. A 10 minutes and 20 seconds file took 12 minutes, 28 seconds to encode with H.265/Handbrake 1.0.7 (64 bit).
That same file took 2 minutes, 40 seconds to encode with H.264/Handbrake 1.0.7 (64 bit). Original H.264 H.265 Size 1.6 GB 501.5 MB 461.9 MB Encoding Time N/A 02:40 12:28 The good news is that we get a size reduction with H.265, but by only about 8%, and it take nearly five times longer to encode the video. Since the original video is about 10 minutes long that means H.265 is encoded at less than than real-time. So even if there’s been great progress compared to previous, personally, I would not rush to transcode my video library (Handbrake supports batch processing) to H.265 yet, and wait for some more improvement to H.265 support in HandBrake. CPU Usage Comparison Now, there is a very definitive downside to H.265.
It is CPU intensive to decode as well. Check out the two VLC instances running in the screenshot below: The 13.6% VLC Player was responsible for playing the H.265 encode.
The 6.5% VLC Player was playing the original H.264 encode. While the delta varied, the H.265 encode never went below the H.264 encode in CPU usage. While the file size savings for H.265 are admirable, most of what I have will have to remain H.264 because of this CPU usage. Coupon app for computers. If the Plex transcoder consumes twice as much CPU to decode H.265 as H.264, I’ll only be able to support half of the streams I currently do – which is already at maximum.
Similar Tests: In short HEVC encoding is CPU-taking. If your computer is a high-end one and has GPU-enabled NVIDIA product, you can use the GPU for really fast transcoding. But, ffmpeg has supported GPU acceleration，including nvenc(Nvidia) and QSV(Intel ), but the current version of HandBrake doesn’t support NVENC, and it can’t support QSV very well.
That is because Handbrake doesn’t use ffmpeg but libav and NVENC hasn’t release of libav yet. Handbrake team said they didn’t have the plan to add NVENC.
