    I've just transcoded an AVI film on my computer so I can burn it to disc and play it on my DVD player. I read that video on DVDs is MPG2 and audio is AC3. So I set up the coder to use those as output formats.

    I didn't alter any other settings - just left them on default.

    Video is fine and everything seems to have coded perfectly, but audio volume is really really quiet. Working but almost inaudible. I can change the audio output settings and transcode again, but don't know what I'd do to ensure it will play on DVD.

    Any advice?

    Thanks

    With AC3, dialogue and softer sounds will sound quiet, and louder sounds will be about the same level as your other videos.

    AC3 filter is fine for playback on your PC, but if you want to change the levels for encoding to DVD you will have to demux the audio back to mono wavs, increase the gain on each one, then re-encode.

    OR...

    Try using "Canopus Procoder" to convert AC3 AVI to DVD. You can increase the levels in the AC3 filter before running Procoder, with no demux required.

    Thanks. Finally solved this quite simply by checking the 'normalize' button. Sound then restored to full volume.
