I am currently working on a gaming "frag highlight" video. My objective is to put some slow-motion effects at some interesting parts of the video. I attempted to use Sony Vegas 5.0 to do the slo-mo as I heard it was one of the best programs for that purpose.
I was playing around with the program (first time using it) and this is what I produced so far for one clip. I used velocity envelopes (slow parts at 24%) to create the slow-motion and also made supersampling 2x at the slow parts. I uploaded the video so click this link to check out what I did (only 1.34MB), http://s88274840.onlinehome.us/test.zip .
Two problems however:
1. The slow motion parts arent really "slow", instead it feels like lag. It's playing frame by frame which is NOT what I want. What I want is to play certain parts of the video slowly and smoothly like you see in sports replays.
2. The quality of the video is relatively garbage and the size is an enormous 4.15MB for only 14 seconds! I rendered the movie as an .avi using the DivX 6.0 codec at 640x480.
I really have no idea how to fix problem 1. I was told to add supersampling but it seems like there's no difference with or without it. I was also told to record my gameplay at a higher FPS (this one's using 60) but there's still no difference (used 30 before).
What can I do to create better slow motion effects and get better rendering quality with a smaller file size?
