Sony a7sEarlier in the week, we shared a comparison of the dynamic range of the Sony a7S to a few other popular cameras, and the results were enlightening. It turns out that the combination of the massive pixels of the a7S sensor and the ability to shoot with an S-log2 gamma curve provides for some impressive dynamic range, to say the very least. Of course, we all know that no camera system is perfect, and the a7S is no exception, especially in regards to rolling shutter. In another comparative test from Cinema5D, they measured the effects of rolling shutter on a variety of popular CMOS cameras, and unfortunately, our beloved a7S didn’t fare well at all. More »

Rolling ShutterAs filmmakers, we may think that distortion issues caused by rolling shutter — the wobbles, smears, and skews alike — is a reality that only affects us in the movie world. But, these distortions occur in our natural world all the time, and on a massive scale — even a supermassive scale.  In this excellent video by Vsauce, hosted by none other than the YouTube science guru Michael Stevens, we explore the rolling shutter effect, which, yes, is common in many digital cameras, but is also a phenomenon affecting the way we perceive Andromeda, as well as the rest of our awesome universe.

It’s been one of my pet peeves ever since the advent of digital cinema cameras: at the same frame rate and shutter speed as a film camera, digital sensors looks more stroboscopic. There’s more jutter and I find it distracting. For a long time I couldn’t explain what I was seeing until Adam Wilt explained why in a piece about RED. Now Adam’s the first to bring my attention to a new product called a Time Filter from Tessive. If you want a smoother shutter rendering on your digital footage, this is a serious innovation — brilliant, in my opinion. More »

Adobe has just previewed “Warp Stabilizer,” a new After Effects-bundled tool that fixes camera shake and rolling shutter artifacting with a simple drag-and-drop operation. Or so they claim; their technology sneak peek certainly makes it look like magic. While there are plenty of camera stabilization plugins on the market, this one fixes camera shake across all axes and will presumably ship with the next version of After Effects (instead of requiring a separate purchase, like many stabilization plugins). One thing I had in mind as I watched this demo: 4K. More »

We all know one of the chief drawbacks to shooting with (current generation) DSLRs are the rolling shutter artifacts that show up on shaky or fast-panning shots. It turns out that iMovie ’11, in addition to interesting movie trailer templates, includes a filter that can decrease or eliminate these annoying artifacts. Here’s a comparison from Nino Leitner of some Canon T2i footage, before and after using the iMovie ’11 filter: More »

Rolling shutter, aka “jellocam,” is one of the chief drawbacks to shooting with large CMOS sensors. Other than to avoid whip-pans or shaky camerawork, however, there’s not much shooters can do about it in the acquisition stage; is there a good solution in post? CoreMelt is a software company that’s just released a Final Cut plugin designed expressly to reduce rolling shutter artifacts. More »
