Motion Blur transitions - a demo video (tutorial in progress)

[jonray]

Hi @bentacular, thanks! I’m working full steam ahead with the tutorial, but just for you here’s the process in a nutshell:
Method 1:

1. Make a “Slide-Out/Slide-in” transition of 7 frames duration. Use a 7-frame transparent clip as a guide.
   
   
2. (My Eureka moment no.1!): export just the 7-frame transition as an Mp4, then re-import, place it above the transition.
   
   
3. Apply a Blur:Box filter (99px width, 0px height).
   Problem: dark areas on the left and right edges.
   
   
4. (My Eureka moment no. 2!): add a Size/Pos filter, set to distort, drag out the dark areas left and right so they disappear.
5. (My Eureka moment no. 3): to make the transition slightly slower, apply a speed of 0.8, or maybe 0.5 to just the transition Mp4.

Ta DA, seems to work…

Method 2:

1. Export as a frame: last frame of clip 1, and first frame of clip 2.

2. In GIMP, make a 3840px-wide image of the images side-by-side.Export as a JPG.
   

   

3. Re-import into GIMP, stretch to 10,000 pixels wide. Export.
   

   

4. Import this wide image into SC. Apply a Blur:box filter. Not too much is required since the image is stretched…

5. Apply a Siz/Pos filter, set to distort, set width at 10,000.

6. Keyframe it from “0” to “-8,080” (10,000 - 1,920) for a duration of 14 frames. Trim this transition clip to 14 frames length.

7. Arrange timeline : clip 1, then transition clip, then clip 2 (no overlapping).

Bingo, DONE!

I’d be interested if my Method 2 was the same or similar to yours?
