The massive video editing extravaganza! – 50 tips! Part 6Posted: June 15, 2011
26. Motion control – basics. There’s lot of things you can do with clips. You can slow them down, you can have them run in reverse and you can adjust the speed within the clip itself. This is the kind of effect you can see in most (if not all) Zack Snyder films where a character does something and the footage slows down for a brief moment. Slowing down means some processing though – the computer has to duplicate frames in order to do some slow motion. However you can also interpolate. What is this? Well, interpolation is when the computer takes two frames, scans the difference between them and creates a new frame to go in between. This means you can have smooth motion even when playing in slow motion.
27. Utilise keyframes. There’s often times when you want an effect to come in mid shot, or you want to adjust the effect mid way through. With the help of keyframes, you can. Creating keyframes is easy, and you can adjust values of the effects using them – in fact every variable can have a keyframe. What happens between keyframes can also be controlled, having them static until the next keyframe, having values increase or decrease until it comes to the next keyframe, etc… Some NLE programs will even let you inverse the ordering of the keyframes.
28. Audio – dedicated programs will always win. No matter how good a video editing programs’ sound manipulation, there’s always going to be dedicated audio programs that do more. Even AVID has Pro Tools to import to. Sony Vegas also has the likes of Sony ACID and Sony Sound Forge. Why is this? Well, to be quite frank, it’d push the memory needed to run the program up considerably. But import of sound into another program is fairly easy, even AVID allows you to transfer markers and even the video footage itself into Pro Tools to allow you perfect the sound.
29. Set a standard audio level. Audio can be rocky if you don’t do it right. The levels can go up and down, being too quiet to understand or being so loud it becomes distorted. There’s usually the green, yellow and red in the audio. You don’t want to go too much into the red. You also don’t want to remain in the green. To help you, on some NLE programs there are tone generators. These help you set a recording level. Try to match the volume of the tone with your audio clips. This bypasses the problem of trying to adjust volume of both the clip and your speakers.
30. Sound gates and effects. There’s always going to be some background hiss, no matter what you do. It’s fine, but if there’s too much hiss, you could try using a sound gate. What’s that? It’s an effect that cuts certain frequencies out of the clip. This often needs tinkering with, and it’s always best to put a reduced level of hiss behind the clean dialogue to blend the audio better. Just make sure you’ve got all the dialogue. And other effects that can be placed upon sound include ones which adjusts echoes and distortions, replicating the effects of different room sizes as well as cutting frequencies to replicate telephone exchanges and such. The best thing for you to do with these is to play around with them. You’ll soon begin to get a feel for them.
