I just had a gig, and it went well ( except from some things, but we hadn't practised the whole week together - been to Berlin) The sound was horrible xD With our performance it was ok, but the band after us had the worst sound ever (not due to their playing, but the technician wasn't that good, it was in an old "warehouse" so the acoustics were pretty odd, and the drum was WAY too loud!

I want to put my videos on youtube, but I was wondering, if any of you knew software/and how-to enhance video and audio. Our camera is 6 Mega-Pix but it's not that clear in video, and the sound is crunchy too due to the high volume. I got Sony Vegas and willing to spend money on software that will enhance video/audio quality.

Jesse.

You can try to cut some problematic frequncies or something and maybe remove clicks and noise with some VST plugs, but don't expect miracles man, this things are very hard to fix cause lots of information is lost, or just not present.

Vegas already has some plugins for enhancing video, so possibly try brightness contrast, curves, color corrector etc.
for VST plugs you can use vegas as well, just insert plugs on audio track.

I would have to say that it's not worth the effort. It's likely that the high SPL has caused the microphone on the camera (I assume that's what was used to record) to clip quite severly. This isn't really something you can 'fix'. I'd just live with it, it's very hard to record live even with the correct gear to do it, nevermind with something like a single handy-cam. When I was gigging last we just used to take a line-out from the PA system into an MP3 recorder. The sound "quality" was good but obviously the levels are all wrong but it was just so afterwards we could have a listen to see what mistakes we needed to work on.

If you want to do a proper recording you'll need a multitrack recorder (a multi-channel interface and a laptop and some DAW software such as logic) and a set of mics to mic up everything that you want to record so that you can set the levels later when you mix it.

I have some bad quality videos from a Bosnian gig with Muris. I didn't want to upload that on youtube. When I saw it on my computer I didn't even bother fixing smile.gif You can get 10% max and it will still be bad quality. The other guy showed me his recording of the same gig with the mobile phone, that looked and sounded better smile.gif

It is really hard to fix bad sound and video quality. You might have to fix video settings in Vegas, export just audio file, put it in Sound Forge or some DAW and clean it up. Again that can only do so much unfortunately. Best recording quality will come from mixer no doubt, so try to get that for your next gig wink.gif

The thing with sound is that it is good when the recording device has a limiter built in. Not all mobile phones have one, only some models, and they are not top quality as well, but they do the job nicely. If you have the chance, record the gig with several mobile phones and then combine best audio and video together, this can turn out very nice if the lightning is good enough smile.gif

As others have said it is always best to record direct from the desk for a live gig.

WRT what you've got it may be possible to improve the recording you have Jesse but it would take a lot of time, effort and some pretty expensive equipment and you'd need to be on top of your mastering techniques.

First, you can remove reverb tails by good wave form editing. You've almost certainly got some nasty reverb reflections in the mix smearing the signal. Not easy and time consuming. You need a good wave form editor like Wavelab or Audition 3. You can also use this to remove some unwanted noise events.

Second, limit and gate the drums. You can do this in software or via hardware with something like a Manley Slam.

Third ,you can eq balance the audio spectrum to attenuate/gain eq spikes/troughs and achieve the overall eq balance that you want. This is quite specialised mastering work but is possible using software like Ozone or by doing it manually with a good mastering eq.

Fourth - and the hardest, it is possible to do something with over compression - you need to upward expand the signal's dynamic range again. This is the hardest bit and really requires something like the Weiss DS 1 MkII mastering compressor - that is a bit of very specialised and expensive kit (about 5000 UK pounds). Note - a downward expansion using a gate won't achieve this, nor will a standard mixing quality compressor. As has been said many time compression is very hard to remove once its there - so only compress when absolutely necessary and use the least possible.

Fifth increase the bit depth and frequency and re-render it - take the wave up to 24 or 32 float at 96 or 192 and you may be able to reduce some of the clipping a bit by increasing the apparent dynamic range. I'm guessing you've got a 16 bit mp3. You can possibly get it better by taking it through a pro end AD/DA like a Lavery Blue or better and hope that the increased word length with good dithering helps improve things and reduces distortion. You can try re-rendering in software as well but you'd need to use software that has a very stable clock and a very good algorhythm for dithering. Most standard DAWs and the AD/DA on most pc audio cards do not have good enough internal clocks and dithering to do this well enough.

To do all this would require a fair bit of mastering experience, time and some very specialised equipment. Assuming that you can't do this then to get someone to do it for you would be expensive. You could probably try to remove the reverb tail, balance the eq spectrum and re-render though yourself. How much it would improve things though depends on how good you are at these techniques and how bad the file is.

For 5000UK pounds you can buy:

- set of stage microphones
- cables
- mixer
- digital recorder
- some rack gear

and still have a spare to buy everyone a well deserved drink after the gig smile.gif

I recorded a couple of live gigs properly on 24 track recorder. It took me 5-6 hours just to set it all up. The hardest part is when you ask the sound engineer to get some outputs from his mixer. They look at you like you're an UFO. Then you both need to make sure that the sound is not clipping on either his desk or your recorder. That requires serious soundcheck. After you have your recordings done then you need to import it all into your DAW (unless you recorded straight into your DAW through some serious soundcard with that many inputs). Mixing a live gig is pretty messy job. You never know what you're gonna end up with but for sure that's better than just a camera mic. Everything needs to be set up properly on stage from the very first step if you want to get some good results. That requires some planing and you need a team of 3-4 people to help you. Quite interesting job smile.gif

This is probably one of the best industry job for recording engineers. These guys really need to do their best to make live recording sound like its going to sell.
Very interesting thread by the way smile.gif

I know and agree Ivan smile.gif .

TBH if I had 5000UK pounds to spend on kit I'd go with your option mate smile.gif (just wish I had 5000UK pounds in the first place wink.gif ). Just pointing out the cost of a Mastering quality compresser that could possibly do part of the job Jesse is on about.

Basically, and to cut a long story short ,it would be expensive and /or very time consuming so Jesse needs to consider whether it's worth it.

Just making a small joke out of it, please don't mind me smile.gif I would love to have all those mastering gear racks so I can play with them it sure sounds like fun to manipulate sound like that! smile.gif
