Can you increase volume of ADPCM sound in movie?

[johnharlin]

I recently purchased a wonderful Casio FH100 digital camera and recorded a HD video.

I opened the video with Gspot 2.70a which says that the AVI video is in MJPG and that the sound is in 0x0011 (DVI ADPCM) 44100Hz 354 kb/s tot (2 chnls).

I eventually want to post some videos from the camera on youtube and want to make sure the sound volume voice recording of the movie will be high enough. Is there any way or program that will increase the volume of this sound format as well as keep it normalized?

Demux and use an audio editor like audacity, goldwave, etc. Mux back to the avi. Mux/demux with for example virtualdubmod, avimuxgui.

You can probably use VirtualDub or VirtualDubMod directly:

1) File -> Open Video File
2) Video -> Direct Stream Copy
3) Audio -> Full Processing Mode
4) Audio -> Volume... adjust as necessary
5) File -> Save as AVI

VirtualDub(mod) doesn't have an automatic gain feature (normalize). Exporting to Audacity would give you that ability. AviDemux has such a feature and wouldn't require the demux/mux steps.

Thank you both. That is really great.
