I'm on Win32. Thought I could do a format shift with AAC using FFMpeg and ended up surprised, frustrated, and spending two hours finding out that nothing works because all public builds of ffmpeg don't have aac encoder options enabled, and cannot be publicly distributed. Even the ones that are supposed to be freeware. The only option is the built in one, which apparently sucks. I found a bunch of posts talking about how easy it is to compile ffmpeg yourself on Linux. I don't have Linux, so I can't compile my own, and don't wish to spend more hours on it. Does anyone encode to aac for sound when using ffmpeg? If so, are you just compiling your own ffmpeg to do this? Or are you using the built in one? Or is there something I'm completely missing? I haven't been this frustrated and confused on something like this for a long time.

1. Are you SURE you want to encode to AAC? 2. Maybe use the Nero encoder instead, FFmpeg sucks pretty badly in terms of quality anyway.

I use QAAC. Are you just working with audio or are you just talking about the audio tracks of a video you're working on?

Oh I'm not all that familiar with the audio side of things in ffmpeg. Its just a bag of open source encoders. https://trac.ffmpeg.org/wiki/Encode/AAC http://wiki.hydrogenaud.io/index.php?title=AAC_encoders Doesn't seem like its the worst.

Is there an encoding megathread? Every time I look at Doom9 I see something like a (still) stickied megathread on Auto Gordian Knot and lose all hope at ever being able to tell what is current and recommended and what ancient things people are inexplicably coasting with and still recommending settings on. I want to improve my process. Right now my start to finish for backing up something from disc would approximately be:
I want to say I've gotten some handle on what I'm doing, but I'm making poor/no use of video filters for artifact removal or color correction, haven't used any other x264 frontends (I'm thinking MeGUI is something I should look at) and don't know a thing about commercial motion-compensated video denoisers. gary oldmans diary fucked around with this message at 19:57 on May 9, 2015 |

Alereon posted:FFmpeg is a bundle of the worst available, lowest-common-denominator encoders, usually based on some ugly reference code. The output quality is so drat bad it's nearly unusable. x264, x265, prores_ks, etc. aren't considered bad.

Alereon posted:What kind of sources are you encoding, and what are you wanting to end up with? SD film television comedies that I appreciate just fine at 480p, but use more aggressive noise reduction for and lower the constant quality. Particularly interested in how to use more aggressively accurate detelecine and decomb settings than the drop-down default values (the nondescript decomb setting "bob" resulted in numerous scene changes that looked like 111111111212222222 from scene 1 to scene 2 and failed to detect interlacing in many dark scenes) and ensuring that frame server filters are applied in the order optimal for quality which I can't verify at all in Handbrake. HD video where the key interest is reducing the bitrate to where loss of detail would be readily apparent from still frame comparisons, but still not artifacting, smudging important details like facial features and hair highlights, and detracting from the viewing. Step 1 is Am I using the best tools for the job?

Alereon posted:So when I say "FFmpeg" I'm talking about the framework it uses, libavcodec. You can certainly plug in your own libraries and get acceptable results, and for formats libavcodec doesn't support where you're forced to use a better library you will also get better results. Well other than the shittier codecs in libavcodec(which I don't think many people use), ffmpeg is a pretty good CLI tool with a good set of included codecs and for most uses(h.264, pjpeg, prores, HEVC) I don't see any major issues. Not the greatest for an end user who's not going to touch a shell but its indispensable to a lot of industry.

Out of curiosity, did the forking of FFmpeg to Libav actually change anything important or improve the quality of the encoders contained therein? I haven't followed it in quite a while but I always got the impression that the decision to fork the project was more over political issues than technical ones.

i found this github project https://github.com/jb-alvarado/media-autobuild_suite it downloads and compiles ffmpeg for you and you can select all the non free codecs

What's the best way to save small sections of lossless video to carefully compare video filter results?
