I recently committed some new video effects: Fade from Black and Fade to Black. These are to provide more convenient and obvious alternatives to keyframing the brightness (which did not work very well until very recently, BTW) or transitioning with a black clip. However, I made these linked to the audio Fade In and Fade Out adjusters in a fashion that warrants some review and discussion. Here were my goals:
1) If there is no Fade In yet, and you use the fader control on the timeline, it does not automatically add a Fade from Black because people often use transitions, and I do not want to presume a Fade from Black. 2) If you add Fade from Black after a Fade In, it automatically takes the duration of the Fade In! 3) If both Fade In and Fade from Black are applied, they are both adjusted when you adjust the timeline fader! 4) You can remove either, but the timeline fader does not go away until both are gone. 5) If you add Fade from Black *before* the Fade In, then adjusting the timeline fader does *not* autmatically add the Fade In, but you can still manually add it. 6) You can adjust the duration of Fade In and Fade from Black independently using the time entry in the effect edit panel. However, it is rather arbitrary at this point which duration the timeline fader reflects. 7) If you have both Fade In and Fade from Black applied, but with durations and you adjust using the fader, they are made the same duration - the duration of the fader, of course. The above rules apply equally to Fade Out with Fade to Black, of course. I did just notice a bug where trimming after you have added a Fade from Black inadvertantly changes the duration of that effect - same probably goes for Fade to Black. Will people expect a Fade to Black on one track overlapping the Fade from Black on another track to create a video dissolve just as it does an audio crossfade? Because it does not. -- +-DRD-+
