![]() Up-to-date syntax: ffmpeg -i input.file -c:v mpeg4 -q:v 5 -tag:v DIVX -s 640x480 -c:a libmp3lame -q:a 5 -ac 2 -ar 44100 output.avi See here for a bit more information anything up to 6 will get you good quality. You can similarly use qscale with libmp3lame, where the range is 0–9, with lower numbers giving better quality. This will target a given quality, with a variable bit rate. The qscale range for mpeg4 is 1–31, where lower=better quality/higher filesize, and 3–6 can normally be considered a useful range. See this blog post for slightly more in-depth information. Testing was done by uploading a obscure media file that only FFMPEG and one other obscure framework can decode.Either use a higher bit rate and/or use two-pass encoding, or use -qscale to target a quality level in a variable bit rate mode, rather than a specific bit rate. This is a VERIFIED list of websites using FFmpeg. Template:Cite encyclopedia In any case, many Linux distributions do not include FFmpeg to avoid legal complications. For example, some European Union nations do not recognize software patents and/or have laws expressly allowing reverse engineering for purposes of interoperability. However, these terms of use are forbidden in certain countries. Furthermore, many of these codecs are only released under terms that forbid reverse engineering, even for purposes of interoperability. Such claims may be enforceable in countries like the United States which recognize software patents, but are considered unenforcable or void in countries that do not recognize software patents. Some included codecs, (such as Sorenson 3), are claimed by patent owners. ASF, and thereby the original version of DivXįFmpeg's legal status varies by country.The default MPEG-4 codec used by FFmpeg for encoding has the FourCC of FMP4. Some Windows Media Video codecs, including WMV1, WMV2 and WMV3.Theora (together with Vorbis makes a base for the. ![]()
