MPEG Video - Audio Leveling

Hello all.

Any know of a good program for leveling the audio of a mpeg video clip?

Ideally it would have some type of user defined preset where audio could be leveled to specified peek dB level and applied to all files processed through.

Most of all, it has be preserve Closed Captioning.

Any suggestions much appreciated.
Thanks.

Could you not just use an audio compressor or limiter plugin in your NLE or am I missing something?

For sure Geoffery,
BUT, most DAWs or NLEs will lose the CC metadata, when re-rendering.
I'm thinking, convert to QT. QT pro allows replacing the audio w/o re-rendering the video or corrupting metadata. Though I'm not an expert in QT or CC issues. I have used QTpro replacing audio tracks without having to re-render the video and the metadata stayed intact. I know little about CC.

I see - not thought of that. You could just export the audio, process it and import it back in but would that destroy the Closed Captioning (many apologies but I don't know what that is!)? I've done the QT trick you mention and it works fine,

Thanks for the QT suggestion. I will give it a try.

I should have mentioned that I'm dealing with clips that are post post-production. My extent of editing is just for segmenting clips or clipping off slates.

I have some simple segmenting tools for doing this that preserver CC however they are not have any extensive leveling tools be it video or audio.

Yesterday I tried TMPG Mpeg Editor 3 which has a great audio leveling tool but it wipes out CC.

The biggest problem I have is that the whole process needs to be relatively simple...
