Frequently Asked Questions
Why convert MP4 to OGG instead of MP3?
Three reasons: smaller files at equivalent quality (Vorbis beats MP3 by ~15–25% at 128–192 kbps), no patent licensing concerns for commercial projects (Vorbis is fully open), and native playback in every modern browser. MP3 is more universally supported on hardware (car stereos, older devices), so pick MP3 if hardware compatibility matters most.
Will the OGG sound as good as the original MP4 audio?
Almost — but not quite. The MP4's audio is already AAC (lossy), and re-encoding to Vorbis is a second lossy pass. At Q5–Q6 Vorbis (160–192 kbps), the audible difference versus the source AAC is minimal for most music, inaudible for voice. To preserve maximum quality, encode at Q7+ or use FLAC instead if file size doesn't matter.
What Vorbis quality level should I use?
Q5 (160 kbps target) is the safe default for music. Q6 (192 kbps) for high-quality music. Q3–Q4 (96–128 kbps) for voice and podcasts — Vorbis is very efficient on speech. Avoid Q0–Q2 (64–96 kbps); artifacts become audible, especially on cymbals and consonants.
Does the conversion handle MP4 with multiple audio tracks?
The converter extracts the first audio track. MP4 files with multiple language tracks or commentary tracks will only export the primary one. For multi-track extraction, use ffmpeg with the -map flag.
What happens to the video?
It's discarded. The OGG container is audio-only — there's no video stream in the output. If you need both audio and video, look for a video editor, not an audio converter.
Are there any patent or licensing issues with OGG Vorbis?
No. Vorbis is fully open-source, royalty-free, and patent-unencumbered. You can use the encoded files in commercial projects, games, and apps without licensing fees — unlike MP3 (now patent-free) and AAC (still encumbered for commercial encoding above certain thresholds).
