2015年9月27日 · So, x264 is still the most popular (free) H.264 encoder out there. But it is also still considered ridiculously cryptic as well. There are tons of switches and options in the encoder that allow you to create tiny files that capture an impressive amount of quality.

The cmdline x264 --fullhelp is pretty explicit about output bit depth from 8 to 10, not higher. Weird that -profile high10 is just silently ignored by 8bit x264. Internally, x264 compiled for high bit depth uses 16bpp for storing any 10bit data, so it probably …

I mostly use Virtualdub2 to upscale my videos (although I am looking for other methods) via two resize filters, Nearest Neighbor and Lanzcos3. Recently I am looking at the x264 encoder to encode my

2015年11月22日 · 1) MeGUI/x264 Settings for an explanation of the parameters like keyint. 2) About --keyint --min-keyint and --scenecut for a discussion at Doom9 about how they interact, specifically--keyint is the maximum interval. x264 will insert key frames earlier if it deems them beneficial, e.g. due to a scene change.

Your code tells ffmpeg to generate a H264 video stream using the x264 encoder, and the options below are used by the encoder to decide keyframe placement.-x264opts "keyint=24:min-keyint=24:no-scenecut" keyint=24 tells x264 to forcibly generate a keyframe 24 frames after the last keyframe. min-keyint=24 sets the minimum keyframe distance.

2017年1月18日 · I just want to know if it's possible to encode audio & video at the same time by FFmpeg -c:a libfaac for audio & x264.exe for video. and any example!

2015年1月26日 · On a fast CPU (i7 quad core with hyperthreading), x264 superfast is probably going to be as fast, and look better (at the same bitrate). If you're making an encode where rate-distortion (quality per file size) matters at all, you should use x264 -preset medium or slower. If you're archiving something, spending a bit more CPU time now will save ...

2017年6月7日 · Generally, H.264 and H.265 (as well as others like VP9) are lossy codecs, at least in their default settings with most encoders.

Even though x264 / ffmpeg are Free with a big F, they are just software libraries for encoding video streams into the H.264/MPEG-4 AVC format, which is covered by the MPEG patent. But the threshold for when fees are applicable is fairly high.
