I've been using LumaFusion for a few video projects recently.

I have a question about mirroring a still image.
Is it possible to animate a still image using the mirror effect so that it looks like
one continuous wrap around.
So the wrap around happens horizontally and creates an continuous loop.
If anyone has used the Skwrt app then you will know what I'm trying to achieve in a video clip.

Thank you in advance

I’m not sure what you want to do exactly but does something like this work?:
- put your image on the timeline
- duplicate and move it to the track above the first
- flip the top image and trim half
- adjust the position of the top image

Thank you for replying though that isn't what I'm trying to figure out.

To achieve the continuous wrap around effect I had thought to
move the image whilst keeping the mirror effect at absolute zero
that's when I discovered that the mirror effect is anchored
to the image and not to the actually screen area.
Is there some way to unlink the anchor yet keep it on the clip or image?

I think I have a two solutions to your question. :D

Method 1 requires multiple renders but no key framing:
1. Import your image into the timeline. Enter size and position and set the size to 101.0. (This protects against a black line in between your clips). Exit to timeline.
2. Duplicate the first clip twice so now you have three clips. Double click the second clip a click the flip horizontally icon. Exit to timeline.
3. Apply the “push left” or Push right” transition between the first and second clip, and again between the second and third clip. On the push left transition in between the second and third clip, adjust left side of the push left transition so the effect is one second and two frames short of your project frame rate (1.28 long in a 30fps timeline, 1.58 in 60fps, 1.22 in 24 etc.). On the push left transition in between the first and second clip, adjust right side of the push left transition to one second and two frames short of your project frame rate.
4. Export video to photos. Open a new project. Import the video to the main track.
5. Cut the video to remove every frame in the beginning before the motion starts, and the two frames in between the first and second clip where the motion stops. In the third clip, cut off the frame that is identical to the first frame of your project and every frame after that.
5. Now you should have two clips on your timeline. Duplicate the first and second clips and paste them at the end of your project. If you cut everything correctly, when you play the project you should have an nice loop that repeats twice. If not adjust the frames you cut until the loop is smooth.
6. Delete the duplicated clips so now there are two clips on your timeline again and export the video to photos for the second time.
7. Open a new project, drop in the second exported video as many times as you’d like the video to loop. Export your final project, and import it into your the video you’ve been making.

8. Finish your video and show me.

A second, more time consuming metho that uses fewer renders and is smooth method:

1. Import your image once to the first track, extend it to 4 seconds and duplicate it to the second track and third track.
2. Enter size and position keyfaming for the the first clip. Move the play head to 1 second and turn on key framing (thus making a key frame). Move the play head to 2 seconds, and adjust the position to -200. A key frame will be created automatically. Exit back to the timeline
3. Select the second clip and enter size and position key framing. Move the play head to 0 seconds and flip the image on the track. Move the play head to 2 seconds and make a key frame. Move the play head back to 0 and set the x position to +200. Move the play head to 1 second and set the x position to +200. Move the play head to 3 seconds and set the x position to -200. Exit to timeline.
4.Select the third clip and enter size and position key framing. Move the play head to 3 seconds and make a key frame. Move the play head to 2 seconds and adjust the x position to +200. Move the play head to 0 seconds and adjust the x position to +200.
5. Export the video to photos, open a new project, drop in the exported video in as many times as you’d like the video to loop. Export your final project, and import it into your the video you’ve been making.

8. Finish your video and show me.


Thank you for your question I enjoyed figuring it out!

Why thank you.

I'm in the middle of an album project so forgive my tardy reply.

I'm going to try both methods as soon as possible.

I'll definitely post up the results and show you.

Once again thank you.

@godanglego

Here we go.

I did the 2nd method as it seemed to be much faster.

It achieved the results that I needed.

Thank you very much.

Another question which you mentioned in your methods.

Why is there a line between images at 100%
when theoretically it should be seamless?

Even in fit image mode there is a
line unless one makes the image 100.1%

Okay, I developed my own way
of creating the wrap around effect.

Import clip
Make clip any length you want
Set image to fit
Set size to 100.1%

Duplicate clip

Create keyframe and set x= 0
Go to end of clip
set x= -200

Go to 2nd clip

Flip image
Create keyframe and set x= +200
Go to end of clip
Set x= 0
Put 2nd clip above 1st clip

Duplicate both clips

Go to third clip and flip image (which should be alongside the first clip)
Go to fourth clip and flip image (which should be alongside the 2nd clip)

Export

Create new project

Import rendered clip and mirror

Very smooth results, going to be using it all the time.
