Removing Audio Problems Part 2: Removing Hiss

Jul 29

Posted by Adam in Equipment, Technology, Tools, Tutorials | 2 Comments

Recently, I posted an article about the basics of removing audio problems, and the limitations that you face right out of the box when you go to fix some nasty audio. This time around, we are going to talk about removing a very specific type of audio problem: hiss.

What is Hiss?

Not to be confused with hum, hiss is a persistant noise on a recording that sounds like … well … hiss. Turn the sound up loud enough and you will almost always here some on your recording. A low levels, it isn’t much of a problem.

The problem is when you have hiss on a recording that is distracting – say from a bad microphone or from turning up low dialogue. You could also be trying to restore an old recording that has hiss on it. Wherever it comes from, however, it’s annoying and needs to be destroyed.

EDLs – Edit Decision Lists

Jun 29

Posted by Adam in Technology, Tutorials | 4 Comments

For the people who grew up in the non-linear era with Adobe Premiere and Final Cut Pro, we’re a little spoiled. Actually, a lot spoiled. We can edit something from beginning to end on our computers and not really give that much thought to the process going on underneath the hood.

That wasn’t the case before, and still isn’t the case in many production environments. You see, more often than not, we modern editors are doing something without even noticing: we’re combining offline and online editing. Essentially, it used to be that you captured much smaller, lower quality versions of files, and edited those. That was offline. Then, you’d send your edit to another department (or do it yourself) and they would do the online editing, meaning they would put in the full quality files from the source tapes, color correct, etc.

Now, you probably capture at full HD and edit at full HD because our computers can handle it. It’s simpler, and for a smaller operation, it makes sense.

But even though we’re editing in different ways, the fundamentals under the hood are still the same.

Since it’s Monday, I thought we’d go ahead and get a little bit of knowledge going for the week. Then the rest of the posts can be GI Joe videos and fart jokes.

So, let’s talk about codecs. You know you want to.
