![]() You'll find more information at Hardware vs. If you need a high quality hardware encoder then you will be paying more for it. It is a great choice where speed is key and where quality loss for a given bandwidth (or greater bandwidth for given quality) is acceptable. The hardware encoder in your graphics card is enough to do the job, to do it quickly. It will have shortcuts and trade-offs in order to keep complexity down.Īs a result the software encoder will get better results 99 times out of 100. It might be the only job a hardware encoder can do, but it requires a massive amount of real-estate to achieve the same level of complexity as a full-featured software encoder. Use the ' Extract' function the you can burn them from ' Overlay ' section. Also, couldn't choose which audio track of that mkv I want to keep in the resulting mp4. If you want to convert to video editing formats, Shutter Encoder is made for that. Hardware encoders will always be worse than software encoders, unless they are specifically tuned to produce high quality results which would result in them having far higher complexity and therefore cost in terms of both silicon real estate and development time. Handbrake, MakeMKV and the old faithful format factory all jump to mind. the crf parameter in an encoder does not necessarily have the same effect in another encoder, and the same value can result in completely different effective quality (the parameters and their scales are not standardized).īecause hardware encoding uses fixed function blocks which are far less versatile and adaptable than software encoders. ![]() And the point is that not only the algorithms are different, but also the parameters do not match between them: e.g. ![]() Using the "hardware acceleration" is definitely not using the same encoder ported to a GPU (or to any other hardware accelerator), it's actually using fully different encoder (since you are on a Mac I'm not sure which one is selected by your software, I know that Apple provides its own encoder). There exist also H.264 encoders that run on GPU, and they are generally provided by the GPU vendors: QSV for Intel integrated GPUs, nvenc for Nvidia GPUs, etc. If you encoding at the same bit rate for both the file sizes will still be the same. Do h265 8bit and you'll have smaller files and same colour. 10 bit is more data even if it didn't originally exist it is no coding in the data regardless. The most widely known is x264, which is the default encoder in ffmpeg. H265 10 bit will be similar to 8 bit h264. To add upon the answer by is a video encoding norm, and there exists different encoders (or codecs) that can produce H.264 video streams.
