Dvx100a Skateboarding Audio

All ALC is going to do is try to "catch" sudden peaks and keep them from distorting. It's not a level control. Since you are taking time to set up your record levels, you're going to get much better results. ALC will help if you have sudden, loud sounds, but won't have any impact on audio that suddenly gets quieter.
 
Also send your mic (whether onboard or shotgun) to both channel 1 and 2 on the camera.

Set one channel a little higher and the other a little lower, one aiming for peaking at the hash mark, one below it.

Then when you edit, if you have loud sounds, you can use the lower channel, and if you have quiet sounds, you can use the higher channel.

HTH
 
very clever^^ but isnt one channel left and one right? then i wont have audio coming from the left/right speaker? obviously im sure there is a way to get around that though, thanks for the tips!

Correct. The safety channel practice is only useful when using a single mic recording to both channels. Since the DVX's internal mic system is stereo, or two mics working to form a stereo image, you want to keep them balanced.
 
yes of course, i do have one other question about my dvx100a but i may just make a new thread about it unless someone can answer it here. When the sun is out and the sky is blue i really want to get a nice blue from the sky that just pops, but a dull blue. when i first started filming i got a really nice blue tone, but since then ive been getting a duller version of that once beautiful sky. i know its probably because of my white balance, but what about my scene settings, is there anything i can change in there to get that poppy blue vibrant sky?

You may have just hit a low-haze/smog day that one time, though it also makes a difference if you shoot with a low sun to your back.

The best way to be able to pull that blue out of the sky is with a polarizer, either 72mm screw-on or, if you have a matte box, a 4x4 or 4x5.6. These filters allow you to "tune out" haze from the sky, or reflections from windows or water.

By the way, one other audio note:

Recording to one or both channels has no bearing on audio playback in post to left and/or right. If you were to record with a single mic, to both channels with the second channel a little lower, you'd pick one in your edit and pan it to the center. You do not have to record to Ch1 in order to get left playback, or Ch2 to get right playback. What's recorded is mostly unrelated to what ends up in the final mix.
