Edius SP: Audio Mixing with Waveform Controls
The Edius SP is a combination of a software and hardware system that offers the best in class nonlinear audio/video editing. The Edius SP combination provides the first ever hardware-based HDV accelerated-editing card available for the PC. The Edius SP software features a strong real-time Waveform and Vectorscope monitor for detailed analysis of footage, while capturing and editing. Below are a few basics of audio mixing based on waveform and vectorscope controls.
Step 1: Launch the Edius Pro Interface
Select the Edius Pro application shortcut from the programs menu to launch the software. You may find the program shortcut on your desktop also. Based on your preferences, you can start a new project or open an existing project. Accordingly, select the “New” or “Open” button. If you select “New”, enter the relevant project parameters on the following screen including output formats and click “OK” button. This will lead you to the project windows.
Step 2: Load the Source File
You will go to the BIN windows and select the video files from your stream folder. Once selected, the clips will show in the BIN windows. You will then select the required audio and video clips for the mixing process and click and drag them to the editing time line. You may put in any number of clips that you wish to edit. Once the right files are in the time line, these may be edited as you deem fit.
Step 3: Read Waveform Monitor and Adjust Y Levels
You will first have to adjust the black level on the waveform by enhancing the black level in the upward direction so that nothing in the scope touches the 0 IRE line. You will then gently begin to move downwards (causing a decrease) so that anything black on the waveform just touches the 0 IRE line. If you wish to see detail in black, then increases it so that it’s a bit higher. This may also be used to avoid black clipping problems.
Next, you will add a node onto the diagonal line and move it in order to change the mid levels (gamma). To avoid white clipping, you will decrease the level downwards until nothing touches the 100 IRE line. You will need to slowly increase it until the brightest part of the waveform is positioned so that the white just touches the 100 IRE line.
Step 4: Audio Mixing and Saving
You will now use the required audio and video files to facilitate audio mixing as desired. Once you are through editing the files, you will save the file and export it into the desired output format (specified in step 1). The output format will again depend upon the intended end use of the footage. You will click on the “File” menu and select the “Print to File” option under the “Print” sub-menu. Click the “Export” button. This will show the save window. Put in a file name and click on the “Save” button to save the edited file.
