I am testing out Retimer SD from your trial download and finding it hard to get rid of artefacts on the foreground, There is very little instruction on using Retimer with FCP. I have and image of a plane coming into landing with a metal fence in the foreground. Once slowed down the bars on the fence get all scrambled.
 
Any suggestions ? How do I apply an effective mask or use Retimer RT to fix this in FCP ?
 
Also I wonder how when varying the speed of a retiming I can make an intermediate sequence of the right length (as I don't know exactly how long the resulting material will be ?). Is there an easy way of gradually slowing down material  - from 2 X to 10X by the end of the shot ?
 
I need to make sure this works before I commit to to purchasing the product - its quite an investement for a video artist. All my videowork is retimed (usually through film optical printing or basic FCP stretching) but the results with Retimer so far are fabulous when there is no extrenuous information.  
 
Finally is there any point in deinterlacing the video frames with Fields Kit for example - and does Retimer differ vastly from Reelsmart's Twixtor ?
 
Sincerely

Mattes are really effective for fixing artifacts occuring in the border foreground/background. Typically, if your foreground moves and your background isn't moving, you will be likely to notice effects where the motion of the foreground is partly applied to the background. By simply drawing a matte around the moving area Retimer is capable to compute the foreground and background motions separately and combine them to get the best result. All you have to do is to draw the matte!
 
You have a total control over the acceleration of your movie. It is possible to animate the retime factor as you want, starting to go twice slower, later on 3 times faster and finish with a 10x slower. There's no limit on the retiming factor meaning that you can virtually slow down by a factor of 2x, 10x or 1000x with the SAME retiming quality. Using the Frame Matching option you can even create reverse mapping or ping-pong effects.  
 
Don't worry about interlacement., Retimer handles it in its own way and is even capable to estimate the motion between fields. Retimer handles the interlacement/deinterlacement on its own and does not require any other plug-in.
Finally, the second plug-in included in the package (RT Motion) gives you the freedom to manually edit the motion whenever Retimer SD introduces artifacts.
 
Retimer SD and Twixtor have the same target. Retimer SD is a all-in-one package (no Fields Kit required for instance) and the plug-in RT Motion gives greater control over the motion estimation. Finally, we include a deblur filter helping to smooth the transition between interpolated and original frames and motion blur filter producing high quality blur at a sub-pixel resolution (so here also no need for a separate plug-in).

Hi ,
I can successfully use Frame Matching as suggsted in your reply to create great looking slowed down footage in Adobe AE ...BUT I am getting background artifacting (woman dancing in foreground , the floor shows ghosting around her legs ) as described  
 
I'm trying to get rid of the artifacting ...
How do I create a matte of the footage to use with Retimer HD ?
How do I load that matte into Retimer and how do I configure it ?
Is there a RT motion tutoral anywhere ?

I generated a matte ,  white (foreground) , black (background) .mov of the dancer using Pinnacle Commotion . I load the orig dancer sequence as the Input Sequence and the Matte as :
 
Foreground Matte Sequence : Matte.mov
Foreground Matte Color : White
Foreground Matte Channel : Alpha
 
with Retimer Method : Frame Matching  
 
but I get artefacts outside the matte (shadow areas ) .
 
Am I doing something wrong ?
