What is VP9 encoding?
VP9 is an open and royalty-free video coding format developed by Google. VP9 is the successor to VP8 and competes mainly with MPEG’s High Efficiency Video Coding (HEVC/H. 265). At first, VP9 was mainly used on Google’s video platform YouTube.
Is VP9 better than h264?
What does the graph tell us? VP9 and h. 265 are (as advertised) 50% better than h. 264, but they are also 10 to 20 times slower.
How do I force YouTube VP9?
How to force VP9 on your YouTube videos. Currently, there are two ways to get the much superior VP9 codec on your YouTube videos: Have a lot of views (more than 1000 on any video) Upload your videos at the resolution of 1440p or 4K.
Is VP9 codec good?
VP9 can use hardware decoding on Intel and ARM devices. Thanks to widespread hardware support, it gives you smoother playback on PCs in most scenarios. That makes it ideal for general use. It’s also the best codec choice for high-quality YouTube videos.
Which is the best VP9 encoder for WebM?
libvpx-vp9 is the VP9 video encoder for WebM, an open, royalty-free media file format. libvpx-vp9 can save about 20–50% bitrate compared to libx264 (the default H.264 encoder), while retaining the same visual quality.
How to encode a VP9 video in FFmpeg?
Examples given are for 2-pass VP9 encoding with FFMpeg. Ensure that your FFMpeg has been built with libvpx support. c:v libvpx-vp9 tells FFmpeg to encode the video in VP9.
What do you need to know about VP9 decoders?
Most of the current VP9 decoders use tile-based, multi-threaded decoding. In order for the decoders to take advantage of multiple cores, the encoder must set tile-columns and frame-parallel. Setting auto-alt-ref and lag-in-frames >= 12 will turn on VP9’s alt-ref frames, a VP9 feature that enhances quality.
Is it possible to do 2-pass encoding of image sequences using FFmpeg?
In FFmpeg the container format or encoding of the input is, in itself, irrelevant in terms of using encoder features like two-pass. is it possible to do 2-pass encoding of image sequences using ffmpeg and libvp9? Yes, it is possible to do 2-pass encoding from a PNG image sequence using ffmpeg and VP9.
