There are a variety of tools that developers can use to get better performance out of their media applications, including ones that are free and fairly easy to use. Benchmark using software processing, then simply change to hardware acceleration and check the performance difference.

Then add use of the Intel Media SDK and again compare running against different codecs and configurations. In order to put the relevance of the GPU evolution into perspective, let's reflect back on advances made in CPU architecture. Stepping back into the s, the first major advance came with Superscaler architecture, providing greater throughput by running instruction-level parallelism within a single processor. Homogeneous cores all identical could run multiple threads at once Thread Level Parallelism.

Heterogeneous architecture, allows multiple processors to have a pipelined data flow where each can be optimized for separate functions of encoding, decoding, transforming, scaling, interlacing, and more.

In other words, there are significant performance and power advantages not available in the past. Figure 3 shows how the GPU has progressed over the past 5 generations, becoming more and more relevant.

Whether using h. Figure 3. Figure 4 shows the dramatic increase in processing power in just the few generations that the GPU has been on the CPU die. Figure 4. Step 1 usually involves running a benchmark for H. FFmpeg is commonly used to benchmark and to do the initial hardware acceleration comparison. FFmpeg is a powerful yet fairly easy tool to use.

Step 2 involves testing with different codecs and configurations. Start with H. Later we'll cover H. It is important to note that when working with video streams, there are tradeoffs between quality and speed.I use qsv h encoder with ffmpeg latest build by Zeranoe on Win7 with media Studio installed.

And I just curious about few things actually, problems :. Does it depend on physical core number? Is the approximate framerate for each model specified somewhere? Is there any? It refuses to encode without this parameter. What does it mean, and why it's important for Ivy? Where to read about it? I doubt, there is a way to enhance it with any parameters, but current video is quite different from the original.

I can forgive the noise and tiny details inaccuracy, but simplification of colours it quite visible even without magnification.

Light-light-yellow became white, and bluish purple became straight purple. Here are the screenshots, 8 mbps, original was x 8mbps too.

Thanks, ViCue. It seems, I was wrong about p. It was x And after days of googling I ended up with a comment of man, who noticed the same Why didn't Intel write somewhere, that being multiplied of 16 is vital for hardware acceleration?? So, I tried with real x and it's okay now. Height must be a multiple of 16 for progressive frame sequence and a multiple of 32 otherwise. I suppose, you mean QSV's crop function. But ffmpeg does not have any interfaces to it, as well as it can not tune all the cool things I see in the manual you gave.

For example, I'd like to tune keyframe interval, which is huge and dumb constant frames, i. The PDF says, a host program can do it. And guess what? It was encoded flawlessly too.

As the uncropped original. Hm, surprisingly it turned out simple: "-g " key works. Well, that's not a scene-change-detection, but better than nothing :. For more complete information about compiler optimizations, see our Optimization Notice.

Detailed Instruction on How to Enable Handbrake GPU Acceleration

Mads Magnus Kristensen New Member. Hi So I have a rather simple question that I was wondering if anyone could answer or atleast give me some insight on. Because right now I see a lot of people justifying purchases of i7 over i5 with "streaming" or "recording". I do understand that an i7 will be way better at encoding when using CPU encoding, but in this case - really how much does it matter? GPU encoding seems superior in all aspects, perhaps except some opinions upon quality of the output?

What is Intel Quick Sync Video? Any Difference from Nvidia and AMD

Sapiens Forum Moderator. It matters as much as you care about having decent quality. When bitrate isn't an issue local recording you can just compensate by increasing it, but for streaming you want the best quality you can get within a fairly limited amount of space, usually Kbps or less.

Boildown Active Member. The quality per bit of hardware encoders are generally pretty bad. Haswell and later quicksync can be acceptable, but in most cases when you're bitrate constrained i. Because you can make up for their poorer quality per bitrate by adding so many bits that it doesn't even matter.

This speed advantage held for all 4k test encodes I did, typically fps faster. Adding 10bit to the mix, greatly increased the quality of the encodes in both their cases.

I have run hundreds of test encodes, using source files from various sources, here are some test encodes. Similarly, if you are using jpeg muxed in a MXF or ProRes Lossless, you need the fastest cpu you can afford with QSV because decoding is a huge bottleneck and QSV does not have hardware decode acceleration for these formats.

QSV also has a maximum resolution support of 4k DCI, so if you plan on using an AVC source that's bigger than 4k, then you are still decoding on the cpu. Further, since Handbrake does not support hardware filtering or decoding at all, no matter what resolution the source is, if you use HB, then the decoding is done on the cpu, so again, buy the fastest cpu you can afford or use ffmpeg directly which supports hardware decoding and filtering via QSV.

Hope someone finds these tests useful. I can afford more efforts, though. No need for a top-speed scenario for me, personally. At least, thanks for your efforts to narrow this topic further. Plus, if you are using Netflix clips as your source for some, not only are you going against terms of use there and potentially putting this site in jeopardy posting them here, but you are using a clip that already has been pre-processed and one which exhibits artifacts based on its original encode which likely is HEVC, and thus unfairly giving an inherent bias towards that type.

Here's additional information to learn more. If your Jellyfin server does not support hardware acceleration, but you have another machine that does, you can leverage rffmpeg to delegate the transcoding to another machine. Currently Linux-only and requires SSH between the machines, as well as shared storage both for media and for the Jellyfin data directory. Hardware acceleration options can be found in the Admin Dashboard under the Transcoding section of the Playback tab.

Select a valid hardware acceleration option from the drop-down menu, indicate a device if applicable, and check enable hardware encoding to enable encoding as well as decoding, if your hardware supports this. The hardware acceleration is available immediately for media playback. No server restart is required.

Each hardware acceleration type, as well as each Jellyfin installation type, requires different setup options before it can be used. It is always best to consult the FFMpeg documentation on the acceleration type you choose for the latest information. In order to use hardware acceleration in Docker, the devices must be passed to the container. To see what video devices are available, you can run sudo lshw -c video or vainfo on your machine.

Alternatively, you can use docker-compose with a configuration file so you don't need to run a long command every time you restart your server. Edit sources.

OBS benchmarking: [email protected], CPU vs NVENC vs Quick Sync

Thank you. Beardedbob Member. In Low motion Nvnec can be ok. Therefore always software x unless you really can't afford a performance hit. My PC is powerful enough. I was just curious what it was.

Also, I don't do any gaming. Mostly webcam,music and my weather station streaming from Weather Underground. Thanks for your opinion. Np, then def software x :-p, how is the weather today? It's freezing Take a look. NVENC is perfectly fine to record with not stream as long as you use a high bitrate.

Intel Quick Sync Video

This gives me the chance to edit the video later on if there's something I want to highlight, which I can then upload to YouTube. Dont be afraid to bump the NVENC bitrate even higher, it doesnt seem to hurt it much its built for the job! The more bitrate, the better the quality but of course you will end up with large files.

Hello, I didn't know where to post this so I thought the feedback section was as good as any If I was wrong please feel free to relocate this thread : I did some benchmarking this afternoon, out of curiosity, so in case anyone is interested here are the results:.

Last edited: Jul 1, Maybe it would be a good idea to capture your test footage from vlc instead of using the video plugin, that way the cpu load from the video is removed from obs and your duplicate frames might also go down.

How did you calculate them? Is the load only OBS or full system load? Filesize could probably be removed. Quicksync quality and also probably speed depends a lot on the intel HD version. Definitely thanks for the time you invested! Hey, thanks for your input, these are good ideas! Both record full system load so not only OBS, but I only had that opened along with Excel and log them in text files, which I used to compute average on the recording period.
