Here you can chain functions together where the output of one function feeds the input of the next function.

The final section tells the Lightworks Pixel Shader compiler how to compile all the previous code. The functions you create here will change the pixel values of your input video according to the mathematical algorithms and GUI control settings you’ve defined, and output new pixel values.

This is where you create the code that will actually manipulate the pixels of your video. The fourth section is the meat and potatoes of the effect. Here you define the number of video tracks you want the effect to work with. The following section concerns the actual video inputs to our effect. The next section defines the various GUI controls that allow you to adjust parameters for the effect with most having the ablility to key frame their values. The first section of the file defines the name of the effect and into which category on the Lightworks effects panel it will be placed. fx filesīefore we dive into the code itself, let’s first look at the basic structure of a Lightworks “.fx” file. The faster your graphics hardware, the faster this processing takes place and the closer to real time playback your system will achieve. I liken it to having a wire mesh screen in front of a canvas (the mesh being the Pixel Shader) and throwing a pallet of paint at it, with the mesh-altered splatters hitting the canvas at the same time, instead of painting a picture with individual strokes. Each frame is transferred to a buffer location in the graphics card hardware and every pixel is run through the Pixel Shader code simultaneously and placed in a new buffer location ready for output or additional processing. The unique aspect of Pixel Shaders is the speed at which they process video.

These Pixel Shaders are the software that manipulates that matrix of numbers in your video file. This language is used to write DirectX Pixel Shaders that Lightworks compiles into video effects that then become accessible from the Lightworks effects panel. Lightworks VFX are written in a variant of the C programming language called HLSL, or High Level Shader Language. What you found is what appears to be source code written in the C programming language. If you’re the curious type, you’ve probably opened several of the “.fx” files that came with Lightworks. Parallel processing for real-time effects Armed with this knowledge we’ll look at how to apply it in the creation of new custom effects for Lightworks.
In my previous article I covered the basics of how computer software, namely VFX software, through the manipulation of the matrix of numbers that represents the various intensities of light and dark in each of the red, green, blue and alpha channels of a digital video frame, creates video effects.
Warning – The following article contains massive quantities of geek-speak. In part 2 of this series, he introduces the language Lightworks uses to create video effects, and shows how you can write your own. This will give you kind of automatic gain on your audio track, of course you’ll need to tweak it to your needs.Gary Hango, an expert in video effects and processing, is also an enthusiastic Lightworks user.
You can also apply “non realtime FX”, and add “volume”, so you can have another +6dB gain (you can apply multiple times).Īnd probably there are other ways, which I’m not aware right now.Īnd at last, but not at least, you can apply “track compressor” (It’s possible both to event, or track,but you need only one – track FX’s already have compressor by default, you just need to switch it on).įor start, you can set threshold to -20dB, amount to 10, attack to 0, release to 200 msec, auto gain and smooth sat. Press shift+V when the audio track is selected, or select the insert menu/audio envelopes. Other approach is to add volume envelope and drag it upwards, you can gain so +6dB (That’s +18dB with the track volume). This will adjust the volume to the maximum that can be done without distortion. (Right click the audio, select swicthes, and look for “normalize”). First you could try to normalize your audio.
