Yes — drop a folder of OGG files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes.
Same-codec re-mux: 10 to 30 seconds. Re-encode to a different codec: typically 10 to 20% of source duration, so a 1-hour OGG → MP3 finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
Why is the MP3 louder or quieter than the OGG source?
