I've learnt a lot today, that i've been doing it wrong in vegas. I used to slow mo only by clicking the clip and selecting 0.25 sample. You're suppose to put the 50p clip onto a 25p timeline, not a 50p onto a 50p timeline and select 0.25.
So i've learnt this, i put the 50p on a 25p timeline and select, disable resample on the clip so that it doesn't lose the frames. I don't see any slow motion on that when i click play. I do then right click on the clip and slow it to 0.50 which i guess will be half speed even though my mind is saying that simply putting the 50p clip on a 25p should slow mo it.

Yes, i couldn't believe how long it had been, normally i just do slow mo as quick youtube ads as a small picture in picture with a full raw clip available so i didn't really notice except during rendering when it was blurring every 3 other frames (i had a 50fps into 0.25 without disabling resample and having it on a 50p ruler.
