Increasing volume on a captured DivX Avi-file

[doc_dread]

Hi,
My situation is:
I have captured a videofile from my TV-Tuner and saved it as a AVI-file with a DivX 4.x compression... but the volume (PCM CD-quality) is very low and almost silent!

My question is:
How do i increase the volume of the avi-file? i heard VirtualDub should do the trick... But how? please explain it as a guide...
i hope someone can help me!
please also send the answer to this email: doc_dread@hotmail.com

thank you

1. Open Video in virtualdub
2. Under video tab, select Direct Stream Copy.
3. Under Audio Tab, select Full Mode Processing. Select volume and decide on how much (in%) you should increase the volume. Generally, you may need 200-300% increase or more. Be aware though that too much increase will result in audio clipping, so do it so that the volume is loud enough without introducing these clips. Under compression, select Uncompresses (if you wish to preserve your original PCM format) or MP3 (which will save you a considerable amount of space with minimal amount of quality loss).
4. Under File tab, select Save AVI and give a name to the new file.

Firstly, DON'T CAPTURE IT USING DIVX 4.xx!!!

You lose quality.

Capture:

NO RECOMPRESSION, CD quality audio, YU12, 320*240, 30/25fps

Then You can encode to MPEG2 in TMPGENC then to DIVX!

It doesn't lose quality cause I tried it 89 times.

...cause I tried it 89 times.

How on earth can you remember that many trials?

By the way, your video encoding method indeed is good in terms of quality, but it's only feasible when there's really a lot of HD space to spare (gigs and gigs of them).

Yeh, I understand what u r saying about the gigs thingy!

How do I remember? Well because many people argue with me (not u) so I need to keep a record of things

Thanks

Thanks alot guys that worked great!!! im very happy for that...
next time im gonna try capturing with no compression - but it takes up alot of space though! but it worth a try

By the way do you know a program that does the same thing to
MP3-files where it normalizes and increases/decreases the volume? i tried a couple of programs but they ruined all my MP3-songs... (damn!)

hope to hear from u again...
thanks again for the help...

Hi, yeh, use EASY CD-DA extracter, it's cool!

No recompression basically produces the BEST picture quality but isn't intended to be kept on the hdd forever, it is designed so that you can acheive high quality and later do editing!

Try GoldWave or CoolEdit

" i tried a couple of programs but they ruined all my MP3-songs... (damn!)"

You should always backup your files before attempting to alter them...
