Nice desaturation effects!
Anyone using Sony Vegas should disable image blending, this video editor is badly configured by default: whenever you press pause, it looks like 8 images are combined. This is, because the source video has 200 fps and it is resampled to a 25 fps output.
These settings should produce clear frames without image blending:
Select the clips you want to modify, go to Edit menu > Switches > Disable resample.
Thanks. I specifically use 200fps for motion blur effect by combining frames with resampling. It provides an excellent smooth video and the feeling of all 200fps in the usual videofile with a frequency 25fps.
Single my fault - I'm not disabled resampling in slo-mo scenes - for example, airrockets: 0:51 and 0:54. At these moments, are clearly seen frames combined.
