"Recording remuxed, but the file may be incomplete" PCM 32 Bit Float audio codec

[IssacI19]

I've been testing out new settings for recording in OBS, and I want to use the "FFmpeg PCM (32-bit float)" audio codec in the recording, but I'm having this weird thing where when I remux the .mkv file to .mp4 in obs, I get a popup that says "Recording remuxed, but the file may be incomplete". It's interesting because the original recording, the .mkv file, is totally fine. It's just when I remux it to .mp4 with that same codec. This goes for any of the other FFmpeg PCM audio codecs. The file is multi-track audio, just wanted to say. Someone, please help

FFmpeg 6.0 does not support PCM inside of a MP4 container.

how do you know what version of FFmpeg you have

Windows and macOS builds of OBS have FFmpeg 6.0.

So I would want to use MOV or MKV instead for PCM audio?

You are already using MKV before remuxing.

So what would happen if I use "Fragmented MOV", do you still have to remux a "Fragmented MOV" file?

[IssacI19]

Because you were right I remixed it to MOV and it works.l but now when I bring it into Premiere or it shows up with one audio track when the file has 3 tracks. It shows up in Media Player Classic, but in Premiere only 1

Worst case is to use mkvtoolnix to demux the MKV into it's elementary video and audio stream and import them separately into Premier if needed.

I have downloaded Davinci Resolve 28 to see if its the file or just Premiere Pro and it pops up as multi-channel audio

PCM audio is currently only supported in MOV and MKV containers in ffmpeg (and in extension OBS).
AV1 video is in turn only supported in MP4 and MKV containers.

So for your usecase MKV is the only valid container at the moment.
