REVISIONFX REESMART MOTION BLUR Rar Fix
Lina Gullace
After Effects has the ability to enable motion blur. But it is a global setting and AE calculates the blur that its preset algorithms specify. Reel Smart Motion Blur has the ability to set a variable amount of blur as well as even to remove blur from a clip. The filter works by calculating motion between two successive frames within a clip and then applying blur based upon the motion it has calculated. As a result, it cannot apply blur to a clip which has been modified to a 3:2 pulldown or to any animation on "2's".
Operation is simple. Select the clip and apply the Motion Blur filter (Video Filters -> AE Effects -> RE:Vision -> Reel Smart Motion Blur). The filter, though, requires a video layer from which to extrapolate motion. Since that will be the clip to which you are applying the motion, you need to drag your clip from the Browser to the Get Motion From well. Then, there is only one parameter to adjust. A setting of 0 means no blur, 1 means normal blur, more than one obviously increases the amount of blur and a negative setting removes blur. It's very simple. Then render and check your results. The algorithm is clean and if rendered in RGB color space the output will be clean.
However what should be easy in Premiere and Resolve never is. The tutorials I've seen all deal with adding motion blur in the Transform panel to moving layers. Not what we want. There is an echo tool, but that doesn't look any good at all - tons of ghosting and takes ages to render, won't play in real-time.
Yep we posted in another thread about adding motion back using Resolve..... I did experiment more so it depends a lot on the scene and background as just a tad of blur does not add too many artifacts in case of complex bg like a metallic fence can cause bad artifacts.
My test was a show jumping horse in a parkour the goal is to pull picture at 1/250 or 1/500 and have a usable video.
So to an untrained eye you can fool them but for real pro work not sure I would use it. But in case where photo has priority I will definitely use it.
The one in resolve is close enough that I'm not going to use ND's for shots on my Z6 anymore.
Also for VFX work results are far better when you pull a key off a high shutter speed and then add the motion blur in post. Makes cleaning up hair work far easier.
I'd be interested to see some stress-testing of it, like Lok did on digital rev when he did star-jumps and it really emphasised the effect. Ultimately it will come down to the motion detection and estimation so it knows what to blur.
Of course, this depends on the order of operations - if the motion blur is applied after the speed change then the input to the effect might only be the frames that survived the speed change, so extra frame rate wouldn't help the accuracy of the effect.
Best results come by using it on individual clips, sometimes adjusting blur amount to avoid ugly artifacts. Generally though, it is an easy way to get motion blur back into high shutter footage. I often shoot handheld DSLR with higher shutter on purpose, so that Warp stabilizer has crisp frames to work from - giving better/ smoother results. Then I run a pass on each clip with the Reelsmart motion blur effect to get the 1/50th motion blur back.
If you have After Effects, try pixel motion blur. I've found it to be quite good, but be sure to bump up the frame count for good results. It is dog slow though, so you'll need to add that to your workflow time. The ReelSmart motion blur is really fast (especially when using graphics card), but produced strange artifacts, at least in my testing.
Yes - Reelsmart can produce artifacts sometimes (usually at the start of a clip), I usually can eliminate these by keyframing the setting to 'ramp' on at the start of each clip. Most post-motion blur effects rely on motion analysis from your footage, not all footage will work first time, and may require tweaking in the effect control parameters. Often a lower than default setting is enough, just to take the edge off the super sharp shutter look.
Why not just use a timewarp node. I did this on a sequence that was shot with a narrow shutter angle, which looked strobey. I used TW, with motion selected and motion blur, it worked well for just adding that little bit of mo blur to take the curse off it.
definitely post..... I don't have any experience with motion blur, but with depth of field when you save out your zdepth channel and apply the DOF in post you can control the amount applied to the image. If you do it in the render it gets "baked" in and you can't adjust it after the fact. Which would mean rerendering again if it doesn't come out right.
Can we achieve 180-shutter-angle results with video taken at non-180-shutter-angle and high shutter speed, then add motion blur in post(premiere pro)? I know that After Effects has the pixel motion blur, but wondering if Premiere Pro has something similar.
I don't know the answer to your question, but presumably actual motion blur will look better than having software guess what was moving between frames, in which direction, and what it looked like in motion. Why are ND filters a pain to use?
REVisionFX ReelSmart Motion Blur Pro - automatically add more natural-looking motion blur to a sequence using ReelSmart Motion Blur. Our tracking technology is at the heart of ReelSmart Motion Blur, so there is no handwork involved. Of course you can add as little or as much blurring as you need and even remove motion blur! Finally, you can create very interesting effects by blurring one sequence by using the motion from another.
ReelSmart Motion Blur features, for After Effects-compatible hosts:
- automatic tracking of every pixel from one frame to the next
- variable amount of blur
- ability to blur one sequence using the motion from another.
- removal of motion blur
- multiprocessor support
- 8 and 16 bits per channel processing (only 8 bits per channel supported within Final Cut Pro). Unclamped floating point image support in After Effects 7.0 or later.
ReelSmart Motion Blur Pro adds the following features
- For all hosts: Support for foreground and background separation using a specified matte. ReelSmart Motion Blur then uses proprietary filling and tracking techniques when working on the background layer, even when it is obscured by the foreground!
- For all hosts: Up to 12 tracking points can be specified to help guide RSMB's motion estimation. By using the tracking points you can explicitly tell RSMB where a pixel moves from one frame to the next in order to guide RSMB's calculation of motion vectors. You can set the position of each point at each frame by hand, but more importantly, these points can often be positioned from frame-to-frame using the host application's point-tracking features.
- For After Effects and combustion: Plugin included that allows you to blur with motion vectors supplied by you... which, most likely, will come from your 3D animation system.
- For After Effects and combustion: When RSMB exhibits tracking problems, you can guide RSMB by simply creating and animating shapes to show RSMB where objects are actually moving. Interactive feature registraion is directed through the host program's drawing and roto tools (splines and polylines), not through a grid of mesh points! As such, there is no new interface to learn.
rsmb does a great job if you isolate the elements that require the motion blur. if the plug in has to compute the entire frame it will try to figure out what needs to be blurred. its not always correct. the only way around this is to render your animation out of cinema in passes and composite in after effects and apply rsmb only to the elements that move. it will look great and render fast but requires some clever render passes to get a good result.
Systems, and Sony Vegas Pro. Twixtor creates highly engaging slow motion shots without the cost of renting a high speed camera. In order to achieve its unparalleled image quality, Twixtor synthesizes unique new frames by warping and interpolating frames of the original sequence by employing RE:Vision's proprietary tracking technology that calculates motion for each individual pixel. ReelSmart Motion Blur automatically adds more natural-looking motion blur to a sequence. Proprietary tracking technology is at the heart of RSMB, so there is no handwork involved. Of course you can add as little or as much blurring as you need and even remove motion blur! This is a useful tool to give video a more film-like feel, and is also useful to reintroduce motion blur for blue or green screen shoots where a fast shutter is necessary to pull a good key. Also included in some RSMB versions is a feature that allows you to blur with user-supplied motion vectors that, most likely, will come from a 3D animation system (see the RE:Vision Effects website for which versions include this feature). Both Twixtor and ReelSmart Motion Blur can see substantial acceleration using GPUs. Note that most currently-sold GPUs will provide customers with much needed acceleration, including even many mobile GPUs for laptops. The total speedup end-users will see will vary once application overhead is taken into account, including disk I/O, internal host buffering schemes, bandwidth of PCIe bus, codec used for footage, as well as features used in the plug-ins.
