Stargirl scoring competition audio problem

Post by zsazsa » Sun Jul 18, 2021 10:17 pm

Hi people,

Spitfire organises a Stargirl scoring competition:
https://www.spitfireaudio.com/stargirl

One problem I have is when I drag and drop the video file into Live 10 then the video works but the audio does not.
The audio shows as a flat line in clip and in arrangement view.

Can somebody help me to get the audio to work?
Why does Live/Matroska(?) decode the audio as 44.1 kHz whilst it is in 48 kHz???


Live shows the file as being 16bit @ 44.1 kHz.
Live default settings are at 48 kHz.
I use the Haali/ Matroska video splitter to play the video.

Ableton Live 10.1.30 Suite
Windows 10 21H1
RME ladyface @ 48 kHz, 48 samples


The video + audio work fine in Reaper (here the waveform of the audio is shown) and in VLC player. So the file is fine.


Video file can be found here: https://d3a0bdvj9eysmp.cloudfront.net/c ... 0MUSIC.mov

File properties as Reaper shows it:
Length: 1:56.199
Video: 1920x1080@23.98fps, Aspect=1.00, Decoding format=I420/YV12
Audio: 48000Hz 2ch 32bps

Using VLC decoder (v3.0.x)
Video: 1920x1080, h264, 23.98fps
Audio: 48000hz, 32bps, 2ch, s24l

Windows also shows the file as 48 kHz

Did you look at the knowledge base articles?
If Live/your audio card is set to 48Khz, then there should be no decoding taking place.

I can't help with the Windows side of things as I don't know shit about it, but one trick you could use since the video is playing correctly, is to extract the audio and then put it on another track.
But in any case you shouldn't worry about the format; just make sure that the video playback is at the right speed - which should be the case as Live handles under-the-hood conversion perfectly (except when it tells you that it 44.1Khz for non-obvious reasons :D ; or maybe that's the Haali thing that's bugged ). Just make sure you're (working and) exporting at 48Khz and everything will be fine.
