Digital Video Stabilization

I learned about the Deshaker plugin for Virtualdub this weekend. So as a trial I ran this video:
http://www.youtube.com/watch?v=ToO6GWUab9c

through the filter, and it came out with this:

It seems to work best on the straightaways (i.e. 0:25-0:40, etc), where its essentially a smooth progression down the road.

Considering the fact that I didn't have to do anything manually other than load the video into vdub and launch the filter, I thought it was pretty frickin sweet (not to mention necessary for handlebar-mounted videos taken on skinny tire bikes).

Very impressive improvement. Almost as good as a steadycam.

Degnaw, have you seen any weird pay back issues after using the deshaker? I've had clips slow down and speed up as they played or the player screen went black. Happened in vdub, WMP and Divx player plus.

I appreciate this thread and the heads up on virtual dub and deshaker. I've been playing with it but am having trouble finding the right settings. I'm also playing with where to mount the camera on my bike. I'm on my third mounting design, the second one on the handlebars. Although the mount is stable, there's still quite a bit of camera shake (even with image stabilizer enabled on the camcorder). Using deshaker, I'm getting a "sea-like waves" effect in parts of videos with the most camera shake. I guess trying to find the right settings for deshaker is a matter of trial and error. I'm hoping to avoid buying a video camera specifically made for sports. However, one question for someone who owns the go pro or similar "sports" camcorders. Do they consistently shoot good quality video with minimal shake, like the clips they post on their sites?

Numtnbkr, check this link http://content.photojojo.com/diy/att...-to-your-bike/. I make the same mount up. My camera is located on the bars at the same point as pictured on the site photos. I'm using a Cannon Power Shot Sd960 without any problems so far.

I'm also playing with the setting in deshaker. The default setting have been the best for me so far.

Gyro,

Thanks for the info. My current mount is very similar to that one and it's the most stable to date, but I'm still not happy with the level of camera shake. Perhaps I may never get as steady a shot because of the area I ride--I'm riding rural, forest roads which can be in bad shape after winter.

Here’s a deshaker test that came out well. This was shot using the handlebar mount and placement per my last post. This is the climb out on a wooden planked bridge in my home town Rochester NY

http://video.yahoo.com/watch/7210237/18787156

I used the default setting on both passes with the exception of changing the “edge compensation”. I found using the default “Adaptive Zoom (some boarders)” caused weird zooming as the video ran. For this test, I used “Fixed Zoom (no boarders)” which removed the zooming issues. I also found using “None (Large boarders)” works well, but the video will need to be cropped to remove the black boarders.

The video online has been heavily compressed by Yahoo. The uncompressed version is much better.
