Converting MOV file without losing audio (saving old tapes to computer)
Hello,
I'm trying to transfer videos from digital8 tapes to a hard drive. I learned that you had to use the DV out to not lose quality so I used an old mac with a FireWire Port to record them with iMovie. It recorded to a .mov file so I wanted to use handbrake to convert it to mp4 but whichever setting I use, there is no audio on the resulting file.
I tried with AAC, AC3, MP3, Opus, PCM, PCM Passthru.
I also tried with MKV format instead of mp4 with AAC, AC3 and PCM Passthru.
The only setting that worked was MOV format with PCM passthru (because it didn't do anything I guess since that's what the file already was?)

( "decavcodec: hb_audio_resample_update() failed
[SWR @ 000001805ea3ba80] Input channel layout '4 channels (FL+FR+UNSD+UNSD)' is not supported" )

I tried with DaVinci Resolve and it did gave me an mp4 with sound.
I saw online that handbrake didn't support PCM audio so it might be just that but I wanted to know if there was any way to make it work and maybe why it is not supported ?
Edit : Things that seem to work for people that could have the same issue...
1- MKVToolNix --> just drop the file and click "Start multiplexing". It converts instantly to a MKV that you can put through Handbrake.
2- Shutter Encoder Replace audio function -> check convert, use PCM or Vorbis and click "start function", then through Handbrake.
3- Avidemux -> Just put the output format as AVI and save. It is really quick.
That's the 3 fast options I found so far that solved the handbrake compatibility issue with the 4 PCM audio channels. I still don't know why though and would be interested to know.
And lastly : This is the first and last time of my life I will touch a Macbook!!
