You need VideoToolbox for this particular tool because it calls the VideoToolbox library from within FFmpeg in order to encode the video.
"Why do I need x264 to encode H.264 in FFmpeg?" is essentially what you're asking. FFmpeg needs VideoToolbox support to work with my tool.
If you're asking why I chose to use VideoToolbox in the first place, it was because I want this to be a macOS-specific tool with very fast encoding speeds at decent fidelity per bit. Hardware accelerated video encoding is one way to make this happen.

vt-enc calls FFmpeg which calls the VideoToolbox encoding framework. Without VT, ffmpeg commands will fail

VideoToolbox is the encoder that FFmpeg links to.

Royalty-free blanket patent licensing is compatible with Free Software and should be considered the same as being unpatented. Even if it's conditioned on a grant of reciprocality. It's only when patent holders start demanding money (or worse, withholding licenses altogether) that it becomes a problem

JPEG-XL is in no way patent encumbered. Neither is AVIF. I don't know what you're talking about

No, there aren't any licensing issues with JPEG-XL.

YouTube serves VP9 video (and more recently a lot of AV1) and I think the Pis only have hardware accelerated decoding of H.264/5 as it stands today

# bdr-ssimu2 Encode, analyze, & plot SSIMULACRA2 scores using a source video file that is encoded with FFmpeg. This Python script generates BD-Rate (Bjøntegaard-Delta Rate) graphs for comparing the performance of different encoding commands. It encodes a source video with various specified Constant Rate Factor (CRF) values, calculates SSIMULACRA2 scores, and plots the results via `matplotlib`. ## Features - Encodes a source video using two user-configurable FFmpeg commands - Calculates SSIMULACRA2 scores (and soon XPSNR scores as well) - Generates BD-Rate curves comparing the two encoding commands - Outputs both average and harmonic mean SSIMULACRA2 plots - Allows for temporal metric analysis subsampling (sampling every nth frame) ## Prerequisites - Python 3.x - FFmpeg - VapourSynth with: - [VSZip Plugin](https://github.com/dnjulek/vapoursynth-zip) - FFMS2 - fmtconv - Required Python packages: - `vapoursynth` - `matplotlib` - `tqdm` See more in the linked Git repo's README!

**Introducing SVT-AV1-PSY v2.1.0-A** ### Features - New parameter `--max-32-tx-size`, which restricts block transform sizes to a maximum of 32x32 pixels. This can be useful in very specific scenarios for improving overall efficiency - Added support for HDR10+ JSON files via a new `--hdr10plus-json` parameter (thanks @quietvoid!). In order to build a binary with support for HDR10+, see our [PSY Development page](https://github.com/gianni-rosato/svt-av1-psy/blob/master/Docs/PSY-Development.md). - New parameter `--adaptive-film-grain`, which helps remedy perceptually harmful grain patterns caused by extracting grain from blocks that are too large for a given video resolution. This parameter is enabled by default ### Quality & Performance - Disabled SSIM-cost transform decisions while keeping SSIM-cost mode decisions, generally improving Tune 3's efficiency & consistency - Additional NEON optimizations for ARM platforms, providing a speed increase ### Documentation - All of the features present in this release have been documented, so associated documentation has been updated accordingly - Build documentation updated to reflect the HDR10+ build option ### Bug Fixes - Disabled quantization matrices for presets 5 and higher due to a visual consistency bug (#56) **Full Changelog**: https://github.com/gianni-rosato/svt-av1-psy/commits/v2.1.0-A

Hi there! We're back with a new micro-release format to announce some exciting changes in **SVT-AV1-PSY v2.0.0-A**! 🎉 ## PSY Updates ### Features - The CRF range, previously capped at 63, has been extended to a maximum value of 70. It can also be incremented in quarter increments of 0.25 - New option: `--enable-dlf 2` for a slower, more accurate deblocking loop filter - New option: `--qp-scale-compress-strength` *(0 to 3)* which sets a strength for the QP scale algorithm to compress values across all temporal layers. Higher values result in more consistent video quality - New option: `--frame-luma-bias` *(0 to 100)* enables experimental frame-level luma bias to improve quality in dark scenes by adjusting frame-level QP based on average luminance across each frame ### Quality & Performance - A temporal layer qindex offset has been added to Tune 3 for more consistent quality across frames when encoding - Minor speed bump to Preset 8 - Dynamic delta_q_res switching implemented to help reduce signaling overhead, which should improve quality especially at CRF ≥40 - Other general improvements to Tune 3 ### Documentation - PNG images have been replaced with smaller lossless WebP images, resulting in faster loading & repository cloning times. - More consistent & thorough [PSY Development page](https://github.com/gianni-rosato/svt-av1-psy/blob/master/Docs/PSY-Development.md), including build instructions - ### Bug Fixes - Help menu formatting adjusted for less frequent underlining - `--progress 2` no longer reports the same information as `--progress 3` ### Other - Introducing **PSY Micro-releases**! Each micro-release will be marked with a letter, bringing a bundle of new features & improvements. The release letter will reset back to the initial `A` each time our mainline version is updated. More info can be found in this project's README & the PSY Development page *Thanks for using SVT-AV1-PSY!* ♥️ **Full Changelog**: https://github.com/gianni-rosato/svt-av1-psy/commits/v2.0.0-A

From the GitHub releases: > *Hello, everyone! We've been hard at work enhancing SVT-AV1 with our additions to the encoder improving visual fidelity. Little by little, we are working on trying to bring many of them to mainline! For the time being, I want to note that major SVT-AV1-PSY releases & mainline releases are not the same, and the codebases differ due to our changes; the version numbers may be identical, but the versions themselves are not, which is disclosed within the encoder's version information.* With that, we're excited to announce **SVT-AV1-PSY v2.0.0**! 🎉 ## PSY Updates ### Variance boost - Moved varboost delta-q adjusting code to happen before TPL, giving TPL the opportunity to work with more accurate superblock delta-q priors, and produce better final rdmult lambda values - Fixed rare cases of pulsing at high CRFs (>=40) and strengths (3-4) - 2% avg. bitrate reduction for comparable image quality - Added an alternative boosting curve (`--enable-alt-curve`), with different variance/strength tradeoffs - Refactored boost code so it internally works with native q-step ratios - Removed legacy variance boosting method based on 64x64 values - Parameter `--new-variance-octile` -> `--variance-octile` *Excitingly, a var-boost mainline merge has been marked with the highest priority issue label by the mainline development team, so we may see this in mainline SVT-AV1 soon! Congrats @juliobbv!* 🎉 ### Other - Presets got faster, so in addition to Preset -2, we have an even slower Preset -3 - `--sharpness` now accepts negative values - The SVT-AV1-PSY encoder now supports Dolby Vision encoding via Dolby Vision RPUs. To build with Dolby Vision support, [install libdovi](https://github.com/quietvoid/dovi_tool/blob/main/dolby_vision/README.md#building-the-library) & pass `--enable-libdovi` to `./build.sh` on macOS/Linux (or `enable-libdovi` to `./build.bat` on Windows). ## Mainline Updates ### Major API updates - Changed the API signaling the End Of Stream (EOS) with the last frame vs with an empty frame - `OPT_LD_LATENCY2` making the change above is kept in the code to help devs with integration - The support of this API change has been [merged](https://github.com/FFmpeg/FFmpeg/commit/69dd1ce610fcffec453a0663c613c9b13165fd9e) to ffmpeg with a 2.0 version check - Removed the 3-pass VBR mode which changed the calling mechanism of multi-pass VBR - Moved to a new versioning scheme where the project major version will be updated every time API/ABI is changed ### Encoder - Improve the tradeoffs for the random access mode across presets: - Speedup presets MR by ~100% and improved quality along with tradeoff improvements across the higher quality presets ([!2179](https://github.com/AOMediaCodec/SVT-AV1/-/merge_requests/2179),[#2158](https://github.com/AOMediaCodec/SVT-AV1/-/issues/2158)) - Improved the compression efficiency of presets M9-M13 by 1-4% ([!2179](https://github.com/AOMediaCodec/SVT-AV1/-/merge_requests/2179)) - Simplified VBR multi-pass to use 2 passes to allow integration with ffmpeg - Continued adding ARM optimizations for functions with `c_only` equivalent - Replaced the 3-pass VBR with a 2-pass VBR to ease the multi-pass integration with ffmpeg - Memory savings of 20-35% for LP 8 mode in preset M6 and below and 1-5% in other modes / presets - Film grain table support via `--fgs-table` *([already in SVT-AV1-PSY](https://github.com/gianni-rosato/svt-av1-psy?tab=readme-ov-file#feature-additions))* ([link](https://gitlab.com/AOMediaCodec/SVT-AV1/-/commit/ae7ce1abc5f3f7913624f728ae123f8b8c1e30de)) - Disable film grain denoise by default *([already in SVT-AV1-PSY](https://github.com/gianni-rosato/svt-av1-psy?tab=readme-ov-file#feature-additions))* ([link](https://gitlab.com/AOMediaCodec/SVT-AV1/-/commit/8b39b41df9e07bbcdbd19ea618762c5db3353c03)) ### Cleanup, bug fixes & documentation - Various cleanups and functional bug fixes - Update the documentation to reflect the rate control *Thanks for using SVT-AV1-PSY!* ♥️ **Full Changelog**: https://github.com/gianni-rosato/svt-av1-psy/commits/v2.0.0
