Description Uwe Dippel 2025-12-22 18:12:06 UTC
Created attachment 187877 [details]
Settings for encoding: acodec aac

SUMMARY
Using the preset MP4-H264/AAC uses the AAC codec, but produces a file name of .WAV.

STEPS TO REPRODUCE
1. Encode a project with MP4-H264/AAC

OBSERVED RESULT
The file extension in the Job Queue becomes .WAV

EXPECTED RESULT
The file extension becomes .ac3 (or likewise)

SOFTWARE/OS VERSIONS
Fedora 42 (and earlier)

Hmm, that render preset/profile should produce a .MP4 file.

Did you switch off the video stream?
Comment 2 Uwe Dippel 2025-12-24 22:48:08 UTC
No, but separate audio streams, should have mentioned that, sorry. So one video track and two audio tracks in a single go. Video comes out as MP4, plus two .WAV.
This isn't any regression, has always been there. Look at my previous reports; I seem to be the one with pluralities of language tracks. So far, we have come ever closer to what I needed. This would probably be the last step. So far, I still have to start two rendering actions: video without audio, and then a plurality of audio tracks without video. I wrote a utility two years ago for semi-automatic assembly, using ffmpeg. 
The purpose is the selection of MP4-H264/AAC, video track, plus "Separate file for each audio track". Currently this produces an MP4 and some .WAV.  Therefore, I still need two rendering actions: Video only, and Audio only (AC3).

This really isn't a big thing, but to my perception still a minor bug: "MP4/AAC" ought to produce MP4 and a plurality of .AC3 files.
