Slowing down gaussian blur

I answered my own question (to a degree) from a couple of posts back. I apologize for posting without playing around with it. So, obviously, I can use iMovie's Gaus Blur to simulate an out-of-focus shot and decide when to end the effect in a clip. Now, however, I need to slow it down. No matter where I end the effect, the scene jumps back into focus pretty quickly. I'd really like it to be very gradual. Any suggestions?

Hi dmchord - could you use a long duration transition to drag out the return to focus? Do you by any chance have the Slick 3 transitions - they include a blur transition. You could then split the clip and apply the blur and transiton to the first part.
Or use slo-mo?
Just a thought.

How do I make CS4 not blur frames together when I slow down footage.

I'm trying to get an effect similar to the oppening credits of Reservior Dogs, but whenever I slow down video, Premiere makes it look all ultra-smooth, which would be nice in most cases but in this one I want to just leave the frames as they are and not have any motion-smoothing. Any advice?

Okay, the Posterize Time effect didn't work (I just ended up with a blank screen), BUT, I found that when I export the video at the frame-rate I want it to be, it creates the effect perfectly. Thanks for your help anyway!

AI effects: Feather versus gaussian blur? which is raster or vector?

i`m looking at feathering versus blurring. both in illustrator effect drop down menu.
from what I I understand the blur/gaussian blur under photoshop effects (in illustrator) will pixelate the edge gradation, but the illustrator effect "feather, will keep it vector, is this correct?
from sample here they both look the same to me, and I noticed the feather effect was gaussian blurring the edge anyway to produce its result,,
from what I can see I should be able to make either of these as large as a billboard and they would both still be smooth gradients? or would the gaussian blur result in pixelation unless I had the vector object sized correctly in the document in the first place to suit the billboard.
what I am trying to ask is how do they work,
my take is the AI "feather" will allow resizing of the vector object shape to any size and not be pixelated on print output,
where as the gaussian blur PS effect, you would need to make sure your object is correctly sized on the correct document size to ensure that it prints smoothly.
any feedback is good,....

wildbirdsketch,
actually can I confirm, both produce a raster gradation to soften the edge, so its no longer vector once you apply a blur or feather correct?
It is, but with raster effects.
asking because if I create a blur/feather, I will have to consider the resolution or not as again I`m assuming no because each time I resize the object the effect recalculates itself as necessary to create the right blur and resolution for that size.?
As long as you keep the Effect>Document Raster Effect Settings the same, the resolution of raster effects will remain the same,
and when these vector objects print (in general for AI), i`ve never known, do they print as Vector or does the RIP turn them all into raster anyway?
Indeed.
just confused on this, I`m guessing their only vector while in illustrator, but once going through the printer it will all be raster via the RIP if thats correct,
Indeed.
its just that vector allows you to scale it to the required output size prior to print and have it print crisply without having to focus on resolution or resampling methods correct?
Indeed.

Script to Edit Gaussian Blur Effect

Hello
I have a complex piece of artwork which has to be scaled up by a factor of 10. No problem except the Gaussian Blur Effect will not scale.
Rather than go through each path and edit the blur amount (by a factor of 10) I had hoped I could write a script which would iterate through every path and if it had a Gaussian Blur Effect edit the value.
Looking in the AppleScript dictionary and online I can't see any way of accessing a path's Appearance or Effects.
I would be very grateful for some advice on this before I start the tedious process of manually changing the values.
Regards
Chris

Hello Mark
Thanks for your prompt reply. I thought as much. It's disappointing really.
The select filters will not unfortunately be helpful because the blurs are different so I can't select all blurred items because I don't want to set them all the same and equally I can't pick one and select all with the same blur amount because I don't know if I have changed all of the items.
I've just got my head down and am selecting them all individually and editing them!
Regards
Chris

Transform Effect and Gaussian Blur creates issues

Here is one issue I cannot figure out how to correct. At times, I apply the Distort - Transform effect on a clip to scale up/down, etc,...then the next clip (which I dissolve to) has the Gaussain Blur applied to it. When I apply the blur the previous clip (with the Transform effrect) shifts. I have the Blur effect above the Transform effect in the Effects pannel and it still does not help. I cannot figure out how to stop the clip from shifting.

I recall a similar bug with Gaussian Blur a while back. I winder if that bug is still around.

Scale gaussian blur

Hi there people,
I created a logo in illustrator with 2 gaussian blurs. I have a normal thin path with a stroke of 2px and a gaussian blur applied.
It all looks good, but when I scale the logo real big or small, the gaussian blur doesn't scale equally.
Can you tell me how I can set the layer/blur so it whill be exactly the same in any resolution?
I understand it happens because the gaussian blur is a photoshop non-vector based effect. this way the blur doesn't scale up or down.
is there any other way to get a similair blur in illustrator? (or any other solution)
greets,
jeroen

Hey Folks -- I'm working on CS3 (mac) and we're having the same problem with scaling the gaussian blur. I checked the prefs and made sure "scale strokes and effects" was checked off as an option but it's still not working. Could that be because the original was done as a filter and not an effect? How can you tell which method was used?

Gaussian blur-- posterization

Hi all-
In a current project, I'm using some blurring effects through time (either a shot starts off blurry and comes into focus, or the reverse direction). All of the raw footage starts out completely in focus.
I have been using the "Gaussian Blur" effect in FCP, but I'm finding that as the blur amount changes through time, the image gets very posterized (i.e. distinct color bands, rather than gradual color shift), especially if there is motion in the shot that I'm blurring.
Does anyone recommend a way to eliminate the posterization artifacts, or a different effect or plug-in that will accomplish my image blurs with a more natural-lens look and quality?
Thanx gang.
-Chris

Yup, that's it, Jerry.
But in another FCP group, a listserve, I belong to, in a recent thread about 10-bit video in Final Cut, some well respected professionals did some testing. Oliver Peters posted this reply:
OK, I've had a chance to get back to this and ran another test this morning. SD input from DBeta to Kona2 using bars from DBeta tape. Captured bars both as 8-bit and 10-bit
media. Created 5 timelines:
1. 8-bit with 8-bit processing
2. 8-bit with HPYUV processing
3. 10-bit with 10-bit processing
4. 10-bit with HPYUV processing
5. 10-bit with 8-bit processing
Applied 3-way CC to the clips and compared no effect, effect rendered and effect previewed (not rendered). When you leave the CC settings at default, i.e. no adjustments, all timelines and all combinations of rendered, unrendered and no effect match each other on the scopes. (Note, that there was a very slight change on the 8-bit processing in the
10-bit timeline.) However, when you actually change the settings, i.e. apply CC changes, then ALL 10-bit and HPYUV combinations show a shift between rendered and preview of
the effect. The ONLY timeline where there was no change was #1, 8-bit with 8-bit processing. Also the 8-bit within the 10-bit timeline had extremely little change, but of course you take a hit stepping down to 8-bit processing. The changes that I saw were minor luma shifts (mainly in the midrange) and subtle vector shifts.

Gaussian blur problem separating backgound, foreground

I want to blur the background of sports photos (still too much in focus even with lens wide open). I put the key player(s) on one layer and the background on another, then apply a Gaussian blur, which gives me a white line where background meets foreground. I can painstakingly rubber stamp extend the edge of the background about 10 pixels behind the foreground and that seems to work, but it's painstakingly slow. Is there a better way or even a plug-in?

Because the player also exists on the background it will grow when blurred and you'll see it peeking around the edges of your subject. I tend to clone the background layer around the edges of the subject before doing the blur (as others said, Lens Blur is better) to avoid what you're seeing. You can also protect that area using a mask. Unfortunately there's no simple button to push...
You could try using the history brush in 'darken' mode and pass it over the offending area. But I think you'll end us with an area that looks less blurred around your subject and that will look fake.

Gaussian Blur = 0 still blurry

Could someone please help me with a search? I'm trying to animate a blur, but at the first keyframe (blur amount=0), it's still noticeably blurry...which will result in a jump during the playback. I disable the blur and it's normal. I've tried searching "gaussian blur amount" and got 5 pages of nothing related. Any ideas?
Thanks.
Jonathan

Thanks for the reply, Tony.
Here's links to images of what I'm talking about. First is the normal.
You can see that the defocus filter is not checked, so this is with the filter off.
Now, compare that to the defocus. example.
You see that the filter is activated and set to 0. But notice that the word "Argentina" is a bit blurry and it's bounding box is a bit bigger. When I turn the filter on and off I can see it move up and down. It's not a render issue because I've rendered it and it's still blurry.
What am I missing?

Gaussian blur and Colour Adjust Hue/Saturation cause freeze-up

After using PS Elements 9 for a year, it has started to give me problems, and I can't find a fix for it online. Choosing Gaussian Blur, or Color - Adjust Hue/Saturation causes PSE 9 to freeze up and stop responding. This just started today, and I'm baffled. Some of the other filters have stopped working, but they don't cause a freeze-up. I've done a disk clean and defrag, but I haven't done anything different to my computer in a long time. I can try to uninstall/reinstall, but I'd rather not if there's a simpler solution. I'm on a Toshiba Satelite Notebook, i5 processor, 64-Bit OS Windows Home Premium. I'd appreciate any insight into this issue.

The editor saved prefs often get corrupted. You may need to rebuild the editor preferences to resolve any conflicts.
Hold down the Ctrl+Shift+Alt keys and simultaneously click on the Edit button on the welcome screen. Release the three keys and look behind the welcome screen by closing it. Or hold down the keys whilst double clicking on PhotoshopElementsEditor.exe (in Program Files x86\Adobe)
You should see a pop up box with the words: Delete Adobe Photoshop Elements Settings File?
Click on Yes
Then wait whilst Elements rebuilds the preferences.

Layered PSD files getting corrupted when applying a gaussian blur.

A file is created then three layers to keep simple a red square is created using the marquee tool then filled with a colour this is repeated on the next layer with a different colour then the third layer is completely filled with another colour.
The first two layers are selected and scaled then made transparent.
Finally the layer in between layer 3 and layer 1 is selected and a gaussian blur is applied this is when the corruption occurs

After file is corrupted Photoshop has to be closed and re-opened because subsequent files that are opened are corrupted.
This has been reported in CS5 and CS5.5 extensively but not so much in CS6.

Below is the steps that where used to create the corruption in the files.
Gausian Blur corruption in Photoshop
Step 1. Create document with 3 layers + Background.
Step 2. Layer 3 - Create a box (Red)
Step 3. Layer 2 - Create a box (Blue)
Step 4. Layer 1 – Fill layer (Yellow)
Step 5. Select layer 3 & 2 & scale down & press
return
Step 6. Change opacity of layer 1 & 2 to 25%
Step 7. Go to layer 2 and select Gaussian Blur filter
Please Note that the blue & Red Box Have changed
colour.
As I Zoom in and out the corruption gets worse.
Sometimes this corruption dose’nt show up until you have
saved & reopened the file.

Issue with Gaussian Blur and Spot Colors

Wondering if anyone has a solution to this issue.
Setup: We are using CS4 + CS5 Illustrator on Mac OS 10.5.X and 10.6.X
We created a spot color radial gradient filled circle over a background of the same spot color. The gradient went from 100% of the color down to 2%. We then applied a gaussian blur set to 50 pixels so that we had a nice smooth transition from the circle blurring outwards over the background with the blur blending into the spot color background.
The problem arises when we select "Retain Spot Colors" on the blur. It fills the gradient circle with 100% solid color (but at the 2% range of the gradient so it appears white) and deletes the blur effect. If we don't select "Retain Spot Colors", it converts the blur to process and we get a banding on our printouts where the spot background and CMYK gaussian meet.
We tried the gaussian blur set at 5 pixels all the way up to 55 in 10 pixel increments but nothing worked. We tried different spot colors, same issue. We know we can do the background in Photoshop and import it into Illustrator as a workaround, but we are constantly editing and changing files and would like to keep everything in Illustrator.
Does anyone have any suggestions on how to solve this or if there is even a solution. We have not tried Illustrator 5.5 and do not want to invest the money in the upgrade yet. We would prefer to stay with both CS4 and CS5.
Thank you for any input.

Hi Mike,
Okay, I have some new information that changes things. I misunderstood what the issue was from the designer. My apologies in advance for the confusion. There are actually two issues but they are somewhat related.
Issue 1:
We are concerned with banding on the outside of a spot color gradient with a gaussian blur over a patterned background of the same spot color. We do not know if this is becasue of the number of pixels on the blur, the version of Illustrator, the blending of the blur into the patterned background, etc... While the banding looks slight on screen it is more pronounced when printed. There are many variables and we have tried everything we can think of to create a smooth transition but we keep getting some banding.
The first image shows what happens when the Preserve Spot Colors in the Raster Effects Settings (found under the Effect menu) is unchecked. We believe that the spot color is being treated as CMYK and causing the blur to be a slightly different color than the spot color background thus causing the banding.
The second image shows what happens when we select Preserve Spot Colors. We lose the blur.
The third image is what we are trying to achieve over a over a patterned background of the same spot color. This was achieved with the Preserve Spot Colors unchecked and also unchecking Overprint Preview in the Separations Preview Palette. However, this brings us right back to the issue with the Preserve Spot Color being unchecked.
Issue 2:
The issue is that we want to print a spot color gradient with a gaussian blur (over 50 pixels). In order to preview the blur effect correctly we have to uncheck the Preserve Spot Colors in the Raster Effects Settings (found under the Effect menu). However, we have recently found out that this will not work with the software our printers use to do separations. If we check the Preserve Spot Color for the separator, it turns the blur into a large square of color (see screensnap below). We have played around with the Add: x Around Object setting in Raster Effects but it has not helped.
3. If we do not select "Preserve Spot Color", the blur looks correct but it is no longer a spot color but CMYK when separated.
I hope that isn't too confusing and makes sense. Again, apologies for the mixup on my part originally. Thanks again for any help.

Making video start fast and slow down?

I am trying to avoid doing this in FCP because I know speed changed video can be jumpy...
Basically I have video that pans and I want to start fast, lets say 600% speed and slow down just at the end to 100%.
I know that in motion it doesn't work with percentages, so how's the best way to go about this. I tried variable speed, but It starts slow then speeds up...
Also, I would like to add a motion blur, is this achieved with activating motion blur in the render tab?
Thanks

Well, I had a bunch of videos that I overlaid with mattes to make it look like one continuous video... But the resulting video was 30 seconds and I needed it to be 5 seconds..
So I exported a QT movie and re-imported it into Motion. Then I just went to the Timing property and changed the speed to variable. This gave me a key frame at the beginning and end of the clip. So I just dragged the keyframe at the end to 150th frame (for 5 seconds).
But since I wanted to slow down the video just a tad at various points, I added a key frame to each area I wanted to slow. I then went into the Keyframe editor and made the interpolation to bezier, then just rotated the bezier to be horizontal. This slowed the video just a tad in each part.
I also changed the frame blending to motion blur blending.
Pretty straight forward once I got the hang of it.

Resize Smart Object keeping Gaussian blur aspect?

Is there any way (that I'm missing)to resize a smart object wich has a smart gaussian blur filter while keeping the same aspect and without rasterizing it first?
Lets say I'm using a background for a product that needs to be out of focus: ussualy I would convert that background image (a not too large JPG in most casses) to a smart object and then apply a (smart) gaussian blur in case it needs to be further or less focused down the road.
Latter when Image is finished and if for some reason (usualy client complaining about image size) I need to resize the document the settings for blur remain the same causing it to be a lot more unfocused in that new smaller size than the original image size.
Is there any workaround (to keep it editable) that I'm missing?
Ty for any help.

I never really thought of that but makes perfect sense.. ty,sometimes you just need a fresh look into things,now you have mentioned it looks perfectly natural,dont know how I didnt thought of that.big thanks.

Gaussian Blur keyframes on timeline - RIDICULOUS scaling

When adding keyframes to Gaussian Blur ...
If I view those keyframes on the timeline, it's bloody useless, because the scaling factor is absurd!
The range on the timeline is 0 - 30,000 !!
WHY?
No one uses gaussian blur with more than 100, maybe 200. Why does it go to 30,0000?
Do they have any editors working over there at Adobe?

He's talking about using the rubberband keyframe UI from within a clip in the timeline. If you apply gaussian blur, click the effects icon (in the clip header) then set the effect display to Gausiian Blur > Blurriness, then you can drag the line up to the top which will indeed show a value of 30000.
It happens this way because the timeline's rubberband UI is not optimized to control each and every effect parameter in the ideal way. Some value has to be chosen as a max for the rubberband to display and that max does nto always match what the user would do. But your problem is valid, and the need for improved effects controls has been heard. Please do submit your own feature request for it though if you want.
The workwround is to use the effects controls panel's paremeter hot text, which is not confined by a vertical ceiling. This is the ideal method for full control over applied effect. In my experience, the rubberbands work best for things like volume, speed and opacity, where there's as many variables, and you just need a way to visualize the ups and downs.
