When the device you are going to watch it on doesnt support it. Adapt as necessary to your encoding requirements. (e). At this point, it would be imperative to mention that decoders have specific constraints, such as expected input resolutions, supported codecs, etc, and as such, it's recommended that in production, to determine and validate the need for hardware-accelerated decoders as failure at this stage results in a failed encode and is unrecoverable. Ive specified it to 3x the 8Mbps (so 21M). I tried H.265 10 bit, H.265 12 bit, and H.264 10 bit, and they all ended up looking washed out compared to the original file. A few interesting options for us are: libvpx-vp9 - which is used be default when you convert to WebM using VP9 codec, libx265 - for H265 code and mp4 container, hevc_videotoolbox - for H265 with a hardware acceleration. First thing I did was to chop out a minute segment and promptly remove the HDR. This method is generally used if you are targeting a specific output file size and output quality from frame to frame is of less importance. Profiles can be set via the -profile:v option, similar to libx264. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup.

What you want is a min quality level at resulting in a variable bit rate. For WebM, it's VP8 and VP9, while in mp4 could be almost anything. It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. Why did the Soviets not shoot down US spy satellites during the Cold War? I started with a 4K HDR example video. Aka a old movie with lots of film grain will need a lot higher bitrate than a modern action / adventure move, which will itself needs a lot higher than an animation. Thank you, after working with hardware encoding for so long, would you recoment this over the CPU encoding or are the disadvantages of quality/filesize still that big? I personally think the extra 2500kbps for the large jump in minimum quality from CRF 24 to CRF 22 is a must. Here is the order in which you have to pass arguments to FFmpeg: (b). With ffmpeg, it'd look like this: ffmpeg -i input.mp4 -c:v libx264 -crf 23 output.mp4 For x265, the default CRF is 28: ffmpeg -i input.mp4 -c:v libx265 -crf 28 output.mp4 For libvpx, there is no default, and CRF can range between 0 and 63.

I mean there are many improvements that have been made in NVENC and NVENC HQ should be equal quality compared to default x264. In this case, you are using two different encoders, so you get different bitrates. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The difference between the input and the output is practically non-visible for 1080p videos. If you have an easily compressible video, it wont bloat the encoded video to meet some arbitrary bitrate. If it doesnt have HDR, the time to encode it doesnt make sense to me as it will take over twice as long vs H.264. Maybe something more visible at lower bitrates? However most devices finally have some native h.265 decoding. But the quality is not as good as expected. Thank you, I did look at the wiki (the H.264 page as well, which is more elaborate), I just wanted to make sure I'm not missing anything else that would be worth paying attention to. There are two most popular tools for video optimization -Handbrake andffmpeg.

However, CRF shows its true edge on the lowest 1%, easily beating out ABR at every turn. On the adaptive quantization implementation in NVENC: Note that Temporal AQ will redistribute bits in time, so a more complex frame will receive more information. As an alternative to -crf its possible to use -b:v, which allows manually defining the bitrate of the video(read more). If we run the command above, it compresses the video down to 542 KB. Could the loss of quality be caused by VLC and its experimental support in deconding h265? By Edgewall Software What does a search warrant actually look like? Do people usually encode with 20+ for 1080p? If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? It means there is less differences between the original and the compressed one. If dark matter was created in the early universe and its formation released energy, is there any evidence of that energy in the cmb? (Well get to that later.). The horizontal line shows this where x264 needs 14Mbps to match x265s 9Mbps, a 5000kbps difference! It only takes a minute to sign up. Open a 2nd command line and encode another .ts at the same time.
