# Blending Frames Using Motion Estimation

Motion estimation analyses the pixels in each frame and interpolates the motion in the clip with sub-frame precision. When blending by mix values or trails does not provide the results you want, motion estimation can often deliver better results.

To process a timewarp using an advanced motion estimation algorithm:

1. From the Timewarp Processing option box, select Motion.
2. Select a Quality option.

   Select: | To:
   --- | ---
   Full Res | Obtain the best results possible with pixel-accurate motion estimation.
   1/2 Res to 1/16 Res | Increase processing speed by calculating motion estimation results based on progressively larger sample areas. The result is less accurate, but these options are useful for previewing purposes.

   TipIn cases where your clips contain less motion, or the moving content contains little detail, the 1/2 Res or 1/4 Res Quality options may be sufficient to process the final result.
