 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?

What?
Its AAC encoders are certainly not the most highly recommended.

 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:
  1. Rip: MakeMKV
    1. Add chapter names from disc
    2. Label commentary tracks
  2. Make SRT Subtitles: Subtitle Extractor
    1. From disc or if from the MKV then with MKVExtractGUI2
    2. SRT Spellcheck and search for multiple italic sections erroneously in a single line (regular expression: <i>.*<i>) in Notepad++
  3. Encode Video: Handbrake (usually processing on a folder queue)
    1. Audio: Passthrough
    2. Automatic crop, Anamorphic: Loose, Modulus 16; High Advanced Video Settings, Constant Quality, Decomb if interlaced, Detelecine and reduce constant framerate to 23.976 if there are repeated frames, Denoise: NLMeans (most recently: 2.0:0.85:7:3:2:0)
  4. Encode Audio and finish: MKVtoMP4
    1. Again, specify constant framerate
    2. Add SRT
    3. Look up metadata, save a cover
    4. Photoshop cover: Denoise filter, History brush facial features and hair, select areas that should be a flat color and use Average filter, color correct, save, add cover to MKVtoMP4
    5. Audio: Pause before encoding to AAC
    6. When paused during encode, examine wav for anomalous single-sample peaks in Audacity
    7. If video audio has a hissing background noise, find a clean 1 second section of it, export sample as wav with FFMPEG, have SoX use the sample to denoise the video WAV
    8. Continue MKVtoMP4 encoding
  5. Use appropriate metadata program to generate an NFO for batch file sorting by category or rating

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.

What kind of sources are you encoding, and what are you wanting to end up with?
Generally what I back up to put on my network server are
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?

Serving frames from Avisynth to FFMPEG seems like the next step for my transcodes. This looks like everything I would want to implement Avisynth filters. I just need to find out how to actually set that up and which filters are most effective.

So back to Avisynth probably a decade after shirking off Avisynth as too complicated to get started with.

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