Influx

Audio tracks missing or error "Frame substitution recursion attempt aborting after multiple attempts on file" : it comes from Adobe, see explanation and solution below

With april update 2025 (v25.2), Premiere Pro and Media Encoder now import H264 .MKV files (see https://helpx.adobe.com/premiere-pro/using/whats-new/2025-2.html ). Those files were already supported by Influx but now that Adobe is supporting some .MKV files it will not always pass some unsupported files to Influx. Some files might not work anymore and have issues (see above). To work around this bad behavior from Adobe, you need to allow Influx to override Adobe : either enable override the .mkv extension in the Settings popup to act on all files, or suffix your file with .influx extension to force Adobe to pass specific files to Influx on a case by case basis.
