First of all thanks for keeping updated this fantastic tool which i am starting to use to encode lossless Hi8 old tape.
However after encoding dozen of video with default settings i noticed some videos audio level are a bit all over which comes from their original recording levels back then.
I dig a bit in the Audio and Filtering options settings to find Gain control and normalize option however i don't understand how they work in my situation but find the help panel helpful.
- I did some encoding test on same file with/without auto gain option activated with default -n parameter
- I analyzed thoses videos in Audacity then Foobar2000 ReplayGain tool and some video have corrected audio level near 89db but some have same audio level before/after applying Auto gain
- Same for normalize some videos i see correction during Hybrid encodind some are not fixed.
Maybe someone could help me to figure which option i should set for my use case:
- I have 80+ captured lossless Lagarith files
- I encode them with x264 and QTGMC(Vapoursynth) with CRF18
- Audio AAC 192kbs
What audio filtering would you recommend me to activate?
Already completed over 40 encoding without audio filtering, would i be able to normalize/fix audio afterward? i read that Regain can be amended via FFMPEG too, would it be the same as encoding them properly with gain control.
