Okay, carda, the best method I could come up with for doing this effect incorporates the use of two masks, and a stock media file that contains the exact camera angle as the footage you are going to want to fade, but with out the actors.Note
: Stock media files must be of a QuickTime file format to be accepted as stock footage in EffectsLab Dv.
When you film your footage that you wish to be faded, make sure you are using a tripod, or that you have your camera on something that can guarantee it will not move through out the filming. Even a change in light can hinder your success with this effect. Film your actor(s) (or the object/objects) that you wish to be faded.
Once you have filmed that, remove what you wish to be faded out of the shot. Remember, make sure to not
move the camera. To avoid complications you may have with this method, film the second video with out the actor/object you wish to fade for the same amount of time as your original clip (at least as long as the original. Longer doesn't really matter). If your second clip is not as long as the first, it isn't that much of a problem, but you may encounter complications, so I am going to suggest you avoid doing it when possible.
As I said above, your second clip must be ready for use as stock footage, so make sure it is QuickTime
. If it isn't, then simply open it in EffectsLab Dv, and then render it as QuickTime. If you have a better method of converting, feel free, as long as it is QuickTime.
Now you want to open your first clip in EffectsLab Dv. Then import your stock footage, and make sure it is at the beginning of your time line. Select the masking option of your stock footage, and then draw a mask around
your footage. When I say "around", I mean for you to have it completely encompass the video. So make sure the mask vertex points are a little a bit away from each of the corners. Masked footage
You mask the stock footage to prevent the picture from being made brighter when the footage over laps your other video. Now that you have made the mask, skip a head to the frame you want the fade to begin. Once at this frame, add
a key frame
. Do this by right clicking, and selecting "Add Keyframe
", in the area illustrated below.Right click here, add key frame
You add this key frame to prevent the masks strength from changing before this point. This is how you control when the fade begins. Now move a head in the time line until you find the point you wish the fade to be complete. The more space between those points, the slower the fade. Once at this point bring the masks strength to zero. It should now gradually drop from a strength of 100
, to a strength of 0
in between the newly added key frame, and the end of the fade.
The first part is now complete, not much more to do. Select the masking options of the original clip (the clip with your actors), and create a mask identical to the first mask you created. The only difference is that you will want the masks strength to be set to 0
at the beginning.Note
: Do not copy the original mask in an attempt to save time, this will most likely cause complications as it did for me. You can try this if you like, but I find it better to simply create the mask a second time.
Now that the mask is created, advance to the point in your timeline in which you began the fade of the stock footage (where you added the key frame). Add a key frame for this mask as well. Then advance further until you reach the point in which you ended the fade of the stock footage. At this point you want to bring your masks strength to 100
There you have it, a fade effect in less time then it took you to film your footage. Both your original, and stock footage videos should fade at the same time, allowing for the appearance of an individual, or object fading.Note
: Please notify me at any time if there is a problem with either picture I supplied above, so that I may correct the error.
Hope this is clear.
