|More Avid tips and tricks for your editing toolkit.|
Again, keep in mind that I work on an Avid Media Composer on the Mac. If you are using Windows, the COMMAND key on the Mac does what the CTRL key does on Windows and the OPTION key on Mac is the same as the ALT key on Windows.
The pass-through track in a chroma key effect.
The trick is understanding how Avid deals with composite effects. If you step into simple key, there are always two tracks: the foreground and background. Usually the background track in a nest is empty, it looks down to the track below the effect track in the timeline to get the background.
The background of the chroma key nested into the effect.
I was surprised how good the results were. All you have to do is apply the effect, go into the MOTION EFFECT EDITOR set the source to interlaced and the output to progressive. For me the results weren't good without the ADAPTIVE DEINTERLACE SOURCE selection checked. Keep in mind, checking the ADAPTIVE DEINTERLACE SOURCE option changes a realtime effect to non-realtime.
I still have issues with the MOTION EFFECT EDITOR as I've mentioned in the blog Motion Effects in the Avid Editing System, but the deinterlacing works great.
Changing keyframes to fixed.
The reason you would want FIXED keyframes rather than ELASTIC keyframes is to make sure FADES you have created stay the duration you have set them to, even after you change the duration of the segment they belong to. For example, if you have a 10 frame FADE at the end of a 2 second title, and you decide to trim out that title to 4 seconds, your fade will now be 20 frames.
If you right-click on keyframe in the ADVANCED KEYFRAMES window of the EFFECT EDITOR, and in the drop-down menu, click FIXED in the bottom half of the menu.
