After you mentioned the fact that the desolve was done in Vegas, I am not sure my suggestion with desolve OFF will work.
A painful work around would be to delete the frame information in deshaker log file for the transition frames, telling deshaker not to deshake those frames.
The only way I see this working correctly and the way I actually do this is to deshake individually all the clips.
Then you can post process the video.
In fact, the best results from deshaker are generated from raw video.
All this time I was thinking that you were desolving in deshaker.

I tried the settings that you had suggested on raw video but it didn't really do anything. Video is still kind of shaky. I wish I knew how to use this thing better.

I am not sure its deshaker at this point. Its just locking into two different frames.
The only thing I would suggest is doing the deshaking first and then processing the video files for effects.
If you think about it, the software gets rightly confused because of the blending effect in the scene.
I will give it a try tonight again but I am not hopeful.

The file I used for the last run was a straight MP4 file from the Flip with no effects at all and there was some shake left over still. I don't know what I'm doing wrong at this point.

Try masking moving objects by using the ignore pixel option in phase 1.
This will force deshaker not to use information which could skew the motion detection.

Also, what settings did you try?
The settings I recommended work very well for most scenarios I have tried.

Can you upload video of the waterfall.
I think I have the desolved version.

I have used the settings I recommended on both videos you provided with high success.
The only suggestion would be to decrease the smoothing in phase two to about 400 which reduces perception distortions.
I would like to try it out on the two scenes with the waterfall that you are having issues with.

Original files, renamed for import in AVIsynth:
https://rapidshare.com/files/3732490733/Two...ater_scenes.rar

The first clip is of the waterfall. The part I had used in my project was after 20 seconds. I had walked on the bridge thinking I would use that later as a test for deshaking but decided to leave it out from the final video.

I deshaked both videos with no issues. Then combined and used fadfx filter. Compressed with camtasia. I am not sure what the camera roll was, I used 47%.

What you are seeing is the relative motion of the camera at the end of the clip. If you dont want this motion, then cut it out. But in general, there is nothing wrong with deshaker. It is the difference in camera motion from one shot to the other, raising up to stopping.

Ah I see what you mean. I'm going to have to pay more attention to that before hitting the pause button. If I'm more careful the movement might still be minor but I'll just snip it out later.

Thanks evropej for your time in working with these files. smile.gif
