Sony Vegas Pro 9 – Rendering sped up .mts files

[Sander Somma] “ALso any idea whats the difference and the resamples do ?”

Resampling is used to change the timing of the video by blending frames together to make new frames. So, for example, if you wanted to slow down the video by 1/2 you would have make 30 frames per second last for 2 seconds. Since the video cannot physically play slower, you can double every frame (i.e., show it twice) and that would make the 30 frames into 60 frames so that it lasts 2 seconds. The problem with this is that it can look as if the video is stuttering if you make too many duplicate frames.

– OR –

You can take frame 1 and 2 and blend them together to make a new frame in between. Then take frame 2 and 3 and blend them together to make a new frame in between and keep doing this until you have 60 frames from the original 30. This is called re-sampling because you are taking a sample of two frames to make a new frame that never existed. If the movement in your video isn’t too fast, this will look very smooth. But if the movement in your video is too great, this can make it look like a double exposure or ghost. This is what was happening to you.

Hope that makes sense. If not, just ask more questions.
