This is a recurring question: "How to apply a continuous Boris Graffiti effect on two clips that you can not combine because they are not adjacent?"

As usual, there is no one answer, and consequently there are several solutions. For my part I found three:

  1. Use the overlay track or title track to insert a clip or a picture that is the total length of the 2 clips that are not adjacent. With a small modification of the effect it works very well ...
  2. If the 3 video tracks (Video, overlay and title) are already taken, there is the solution of intermediate rendering.
  3. If the 3 video tracks (Video, overlay and title) are already taken and the solution of intermediate rendering is not satisfactory for you, you have the option of adjusting the Boris Graffiti effect in two separate effects.
Step 1 : Detailed Examination of the Solutions

1st solution : Using an additional track to apply the Boris Graffiti effect

The Studio timeline looks like this for instance:

  1. First clip cut to 4 seconds;
  2. Second clip cut to 4 seconds;
  3. Insertion of any video clip or any picture equal to the total length of the clip (not visible in the final cut) on the overlay track or on the title track and you apply the Boris Graffiti effect on the latter.

Important : it does not work with a blank title, you must use a video or a picture.

Using an additional track to apply the Boris Graffiti effect

For your video or your image, added to the overlay or title track, to become transparent, you must edit the Boris Graffiti effect and switch to "Advanced Mode".

  1. Select "Background" track;
  2. Change the parameters of the "Host Media" to "Straight Alpha" and check the "Invert Alpha" box. Your background becomes transparent and you can see the clips inserted on the video track in Studio.

After pressing the "Apply" button, you are back in Studio.

The Boris Graffiti effect is edited in "Advanced Mode"

2nd solution : Create an intermediate rendering

If you use all of the video tracks and you are unable to apply the first solution. If you can't save one of the three video tracks by applying one of the tricks that we have already showed you (See tutorial "Using the HFX effect 306-economy"), you still have the option of doing an intermediate rendering ... unless you attempt the third solution. The 3 video tracks are already being used

3rd solution : Cutting a Boris Graffiti effect into two complementary effects

Having specially built two Boris Graffiti effects from an effect cut in two, both halves of the effect are applied to each of both clips.

For the effect to remain in its original design, both clips must have an appropriate length of time but we'll discuss that later ...

Of course for the second intermediate-effect to continue the result of the first intermediate-effect, there will be changes to the key frames of the two effects.

Application of two semi-effects of a Boris Graffiti effect on each of two videos

The first 2 solutions are obvious and require no further explanation. This tutorial will therefore focus entirely on the third solution.

Step 2 : Creation of Two Intermediate-Effects

To create these two intermediate-effects, you will work with the Boris Graffiti Keyframer (See our tutorials ".GRF Files management in Boris Graffiti (animated preview)" et "Creating a Personal Text Transition Effect".

To refresh your knowledge of the Boris Graffiti Keyframer, I'll take this opportunity to show you how to save your workspace. Boris Graffiti KeyFramer stores configuration information for the workspace in an *. xml file.

Save workspace of Boris Graffiti Keyframer

  1. In the Window menu;
  2. Select "Workspace";
  3. Then "Save ...". By default, the first workspace is called "Workspace01. If you just select "Save ...", that's what the Xml file will be named.
  4. But if you want to create another name for your backup file workspace, select "Save to ...". A backup window will open. Remember to select the drop down list "Type" item "Workspace files (*. xml)" and write your workspace file name in the "File Name" field.
  5. You will notice that the recent workspaces are accessed directly from this sub-menu.
  6. When you have saved your workspace, you should try "Snap All Home "... be assured nothing serious will happen. You can then click on your preferred workspace that you previously created to return to your first choice.

The next time you open Boris Graffiti Keyframer it will open in the same state as when you closed it, but you will need only two clicks of the mouse to re-open your personalized workspace.

We will now get down to the heart of the matter by changing the effect from the Library Browser in Boris Graffiti Keyframer.

Loading effect from "Library browser"
  1. In the Window menu;
  2. Select "Library Browser";
  3. In the "Library Browser" window, open "animated / animated text in" and select "Tracking";
  4. Double-click the first effect "track & FadeIn.grf" to load it in to Graffiti Keyframer.
Tracking parameter values in the middle of the effect

The tracks that are gray are tracks whose parameters were modified.

  1. Select the gray "track and fade" track
  2. Double-click the "Toggle Smart View" icon to show only the tracks that have had their associated parameters changed;
  3. Open the "Face" track and select the gray track "Text";
  4. Double-click the "Toggle Smart View" icon to develop only the tracks that have had their associated parameters changed;
  5. Enter the value 00:00:00:15 (15 frames) in the "Time" field, then the cursor will move to exactly the middle of the effect.

By working in Boris Graffiti Keyframer, the effects have a duration (Dur) of 00:00:01:00 (one second). Because we are using US software, the frame rate is 30 fps. This explains why half of the effect is at 15/30 frames from the beginning.

The cursor is positioned in the middle of the effect, you can see the value of 4 parameters scalable at one half time ie at time T = 15 frames.

As with most In effects, text animation takes place between T = 0 and T = 20 images. And from T = 20 images to T=30 images, the text displayed is fixed.

Logic would dictate that we make 2 intermediate-effects, the first ending with the settings visible at time T = 15 and a second which would begin at time T = 0 with the parameters visible at time T = 15 and that would be the Maximum time T = 10 to view the full text of T = 10 T = 30. Even if you do not understand everything, it does not matter because it does not really work well, the connection between the two half-effects is too visible. Then it will still take another pass around the obstacle ...

To circumvent this difficulty and make an invisible connection, we will not cut at T = 15 but at T = 20. This means that all movements of the text will be created by the first intermediate-effect and the permanent display of the text in the screen will be provided by the second intermediate-effect.

You will then see that this technique is valid only for the effects that the movement of the text is done only for a fraction of total time and then remains stable for the remainder of the effect: that is the case for the "Track & FadeIn.grf" effect and many others.

Construction of the first half effect

Creating the first intermediate-effect it will be very easy:

  1. Select the "track and fade" track and drag the keyframe from T = 20 to T = 30 (associated keyframe follows the movement);
  2. Select the "Face" track and drag the keyframe from T=20 to T=30 (associated keyframes follow the movement).

This intermediate-effect will make the complete animation of the text during 30 frames.

Save your first half-effect using the menu "File / Save Settings as ..."

  1. Select your folder;
  2. Name your half-effect "MYtrack&Fade1" for example;
  3. Save it.
Save the first half effect
Creating the second half effect
  1. Immediately save your second intermediate-effect from "MYtrack&Fade1" under the name "MYtrack&Fade2" for example;
  2. Position the cursor at time T = 0 either by dragging or by entering the value in the 00:00:00:00 "Time" field;
  3. Change the "Opacity" value by manually copying at T = 0, the value of T = 30;
  4. Change the "Tracking, Letter Scale Xand Letter Scale Y" values by manually copying at T = 0, values of T = 30;
  5. Save your changes.
Note : You can also use commands in the "Edit / Copy Keyframe" menu (or CTRL + C) and Edit / Paste Keyframe "(or CTRL + V). CTRL + C copies the selected keyframe (and its associated keyframes). CTRL + V pastes, on the same track, the keyframe (and its associated keyframes) copied to a new location on the timeline.

You can then apply the two intermediate-effect "MYTracks & Fade1" and "MYTracks & Fade2" to each of the two clips it was not possible to combine.

Step 3 : Back in Studio and Implementation

And this is where the duration of each clip is important. Normally the original effect lasts:

  • 2/3 of the time for the movement of text;
  • 1/3 of the time for the static display of text.

If you want to keep the original concept of the effect, the duration of your two videos will then be proportional to these lengths.

If you want to do a comparative test, you can create a project with the following timeline example by taking the sixth video of "OurFunVacation.mpg" cut to 6 seconds :

Comparative trial of the effect of unbundling and the original effect

This first clip was deliberately cut into two clips of 4 and 2 seconds to apply our two intermediate-effects. It is followed by the same clip but not razored.

On the resulting video, you can see that the end of the text animation exactly coincides in both cases at the time when the teenager pulls his saber.

As I said before, it is difficult to apply the same method on an effect which moves during the whole duration of the effect without seeing the link in rendering. But maybe one of you will find the solution and we will post it for all to see. Thank you in advance ...
