Chad Perkins: Many DSLR cameras have something called a CMOS sensor. …The CMOS sensor looks at your image a line at a time, and it doesn't often read and record …data fast enough to keep up quickly with moving objects, or when the camera moves around quickly. …This creates what is referred to as a rolling shutter effect. It makes straight lines wavy …and generally creates a wobbly look. …Because of that, this is colloquially referred to as jello cam. …While there's not much you can do to fix this completely, there is a fix in Adobe products, …such as Adobe After Effects or Adobe Premiere Pro that can kind of reduce this effect and …all you have to do is apply it to have that fix applied. It's incredible.…
In some cases, you can completely get rid of any rolling shutter problems with this …amazing software, but it is best to avoid it in the first place if you can help it. …
