@Omar123 there are a lot of cracked/pirated copies offered online as "Sony Vegas" and some of the posters above are a bit concerned that you have unwittingly obtained such a version from an unreliable source. Check your order confirmation from MAGIX.
Ouh my bad, you can use Video Stabilization OFX to get rid of jitter. Make sure you know the motion of the clip and choose appropriate motion compensation for greater result:
Tips:
Create subclip or cut the video (if use OFX instead of media level) to get better analyze result.
Thanks for your comments mine version is real version i can show you all the receipt. Vegas pro 19. Unfortunately its still too bad. I used the stabilizer 3 times with no results.
Did you follow @alifftudm95's video - and also his tips? If it still doesn't work, you can upload the clip to dropbox or something, and post the link here. Then maybe some users will try to stabilize it and show you the settings they applied.
If the clip is still not satisfactory - shoot it again, and this time with a tripod.
