Among included libraries are libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf), an audio/video container mux and demux library, and libavfilter, a library for enhancing and editing filters through a Gstreamer-like filtergraph. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects and standards compliance (SMPTE, ITU).įFmpeg also includes other tools: ffplay, a simple media player and ffprobe, a command-line tool to display media information. At its core is the command-line ffmpeg tool itself, designed for processing of video and audio files.

Unredistributable if compiled with any software with a license incompatible with the GPL įFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. X86, ARM, PowerPC, MIPS, RISC-V, DEC Alpha, Blackfin, AVR32, SH-4, and SPARC may be compiled for other desktop computers Various, including Windows, macOS, and Linux ( executable programs are only available from third parties, as the project only distributes source code) Same settings as above but I tried changing the scaling mode to bicubic spiline, and it seems that the quality is close to that of handbrake even if it is a bit slower to convert and the final file is bigger than the first two.FFmpeg being used to convert a file from the PNG file format to the WebP formatĤ.4 (April 8, 2021 2 years ago ( ) ) I used the setting you suggested then I changed the reference frames = 2 to reference frames = 4 and I also set this Color primaries : BT.709 If you want to pursue further, you'll have to post some sample of the source and output videos Here are the pictures zoom in at 150% to see the differences I can't see a difference during normal playback speeds.

Or if you still have the files, open them with mediainfo, put it in text view, and post the info here. For example, the preset and quality value. I made a screenshot of the same video converted with both handbrake and xmedia recode I noticed by zooming in on the image that the xmedia recode image is more opaque and blurry, maybe I have to set some other settings to get a video quality similar to Handbrake? Best place to start is comparing the x264 settings within each program.
