  AE Frame Blending for Reversed layer

  Posted by Noorul Sahabudeen on January 20, 2011 at 12:55 pm

  Hi,
  I just want to know that is there any difference in the processing of frame blending when the layer is reversed.

  I have a layer, by default the stretch is 100%, i enabled Frame Blending for that layer. Opacity for the blending frame comes as follows,
  For 1st Frame – 5.5%
  For 2nd Frame – 89%
  For 3rd Frame – 5.5%

  But when i reverse the layer, it comes as
  For 1st Frame – 4%
  For 2nd Frame – 87%
  For 3rd Frame – 9%

  In both the case stretch is 100%, in second case it is -100% as it is reversed.
  My doubt is why is the opacity for the frames is different?

  I am not having any problem with any conversion.
  My doubt is why should be the Frame Blending result different when we reverse the movie…

  I created a movie in a After Effect with Numbers from 1 – 10 which goes from left to right. Render that movie as RGBA and import that movie.

  Now add a layer for the imported source.Enable frame Blending and seek to frame number 2 of Composition.

  As Frame blending is enabled while rendering frame 2 , it will use frame 1, 2 and 3, and blend those frames with opacity of 5.5% for frame 1, 89% of frame 2 and 5.5% of frame 3. It follows the same pattern of blending for all the frames except the first and last frame.

  Now my doubt is when i reverse the layer, the opacity considered for blending is changing to 3%, 87% and 9%…
