Remove element from video background

Hi! I am a noob at Premiere (CS5), so please excuse me if this is a dumb question. I took some video and, behind my subject, there is a picture frame that either needs to go or the people in it need to be blurred out. Can you suggest how this might be done or point me at a tutorial? I don't know what this technique might be called.
Thanks in advance for any assistance.
Regards!

Welcome to the forum.
The "blurring" is probably the easiest way to handle this.
Duplicate your Clip, and place that above your original Clip. Apply one of the Blur Effects, like Gaussian Blur to that Dupe Clip, until satisfied. Also, other Effects, like Moasic, can be useful. Now, you will only see that Blurred Clip, so you will need to create a Track Matte, and this can be done with a Shape in Titler. Size it to suit the interior of the picture frame, and place it onto Video Track 3. Add the Track Matte Keying Effect to the Dupe Clip (the Blurred one), and point it to the Track Matte/Title on Video Track 3.
Good luck,
Hunt
PS - if one had enough blank wall, with similar lighting on it, one could pull out a section of that wall, and use it to "cover" the whole picture frame. I'd probably use Track Matte Keying on that too. Instead of Blurring, just use the Fixed Effect>Motion>Position, to get the extracted wall section moved to cover the picture frame.

Strange problem with removing element from node

Hi,
I have a problem when I removed elements from a node.
here is the code:
String text = "123456";
IANode nodeA= wdContext.nodeA();
wdContext.nodeB().invalidate();
IBNode nodeB = wdContext.nodeB();
for(int i=0; i<nodeA.size(); i++)
IAElement e = nodeA.getEt_Emp_RespElementAt(i);
if (e.getID().compareTo(text)!= 0)
nodeB.removeElement(e);
else
wdComponentAPI.getMessageManager().reportSuccess(e.getID() + " was not removed");
The node A does have a row with field "ID" equals to 123456.
When running the application, it does write that "123456" was not removed...but it removes it....In fact my table is now empty.
How is it possible if it didn't perform the remove operation for ID = 123456 ?
Thanks in advance.

David,
Because you are iterating node in wrong direction: see my reply to your post Re: Loop problem (seems that you assigns me 2 points without reading reply, and mark it as solved just because you stop solving it
So, in example in this thread, you must iterate node B in reverse direction, get element from B and remove it from B if it has some specific ID.

Is it possible to remove blemishes from video frames with photoshop cc?

Is it possible to remove blemishes from video frames with photoshop cc?

Again, show us reference screenshots and we will advise. Otherwise this could become an endless theoretical discussion. Depending on what you want to do you can import the video directly using Layer --> New Video Layer e.g. when covering up fied spots with a brush blob on a layer on top of the footage, but you may also need to create separate layers for each frame using the Frames to Layers script so you can paint on each of them individually. There's really too much we don't know and the possibilities are potentially infinite...

Emergency!! How to remove elements from a set? or..?

How do I remove elements from a Set?
If I have Set s1and s2, I want to create a new set which consist of all elements in s1 but not in the s2.
Which means, I have to s1.union(s2) and then remove elements of s2.
Is there any method which has this function (remove elment from a set)?
Or is there any other better way to solve this (which doesn't have to remove anything)?
If not, how to design a method which will do this job?
Your help will be very much appreciated.

Hi
you can use method removeAll() from set
s1.removeAll(s2);
so s1 contains all the element not in s2.
If you want to lef s1 unmodifyed you have to create a copy.
Set s3 = s1.clone();
s3.ramoveAll(s2);
bye
Nicola.

Generally, using a different program than Lightroom, e.g. Photoshop.
Note: you can remove objects in Lightroom by stringing dust-spot removal bubbles across them, but that may or may not be preferrable. If you do go that route, it may be essential to position strategically *after* initial placement.

Is there a way to remove elements from an array 1 by 1?

I have an two arrays, and they vary in size depending on a parameter set by the user (both arrays are the same size though, they both can vary in length). What I need to do, is remove elements one by one from the array, and use these as indices for another array. Basically, I built two arrays to store x-values on a graph. At the first value on the first array, I want y values on the graph to move from 0 to Y (any value). Then on the first value on the second array, I want the y values to move back from Y to 0 (creating a pulse, essentially, from the first value on the first array and the first value on the second array). By having each x value act as an indice for the y array, I belive I can acc
omplish this (ie, y =0 up to indice 90, then y = 5, then at indice 100, y goes back to equaling 0). I know this is poorly phrased, but it's difficult to explain. If anyone could help me out, I'd really appreciate it.

jdaltonnal,
Note: to add an attachment based on your comment of 6/12/01 to my earlier reply, I had to go back to this 'answer' mode, which gives me the option of adding attachments.
Per your comment, you have a sequence, so I've added a simple sequence structure and the 2nd array to provide a 250ms delay between each array output. Let me know...Doug

Removing element from vector

I am trying to remove an element from a Vector and using the ff code:
Vector abc = getVector();
int index = 0;
abc.removeElementAt(index);
The element is not being removed, when i go back to check the number
of elements in the vector, it is still the same.
Please give me any ideas to make this work.

Try this,
Vector abc = getVector();
int index = 0;
System.out.println("Size before : "+abc.size());
abc.remove(index);
System.out.println("Size after : "+abc.size());
What is the o/p?

Remove element from multi-surface

Hi there,
I am trying to fix some invalid multi-surface geometries that are derived from a 3D source, many of which have ORA-54514: overlapping areas in multipolygon. I can find out which subset geometry (aka the element in this context) is causing the problem with the VALIDATE_GEOMETRY_WITH_CONTEXT function, and even extract just that element (SDO_UTIL.EXTRACT3D), but how do I remove that element from the geometry (and hopefully fix the problem)? Is there any way to view the position of the element within the geometry in the same manner that the Extract3D function requires (i.e. 0,0,1,1,0,0,7), I can return this for the problem element but not for any of the other subset geometries. Unfortunately I'm using FME to load the geometries and the topology validation here is not as robust as Oracle, which means I need to fix the geometries once they are loaded, but there doesn't seem to be any tools to do this?
Regards
Dan

Hi Dan,
instead of removing the offending element, how about extracting all the correct ones? Should give the same net effect, I think.
Re FME: I find I can usually validate geometry enough that it will at least pass Oracle's Validate, but that's usually only 2D or 2D with a Z-ordinate (2.5D, as some folks call it).

Stefan

Remove element from arraylist, jstl

HI there,
i use bean for an array list
<jsp:useBean id="list" scope="page" class="java.util.ArrayList"/>
then i add element in the list
later i need set up a loop does the following:
remove one element from the list and process it
until the list is empty
is this (romoving elment from a list) possible to be done using only jstl
thanks

No, it is not possible.
JSTL is for use on JSP pages.
JSP pages are meant for "display"
You sound like you are doing processing - this sort of stuff more properly belongs in a java class.

Problem when removing elements from table after apply sort

Hi,
I have big problem with <af:table> and sorting.
When I removed objects from a table without sorting, there is no problem but when I removed
items from the table after sorting, the remain items are not correct.
For example, i have in my table these items :
Item AA
Item CC
Item ZZ
Item BB
Item AA
Item BB
Item CC
Item ZZ
I sort the table and i select the following Items : Item BB a Item CC
The remains item is only Item AA, Item ZZ disappear.
If i resort the table, the missing Item zz appear again in the table.
Here is my jspx :
<af:table var="row" rowBandingInterval="1" width="1050" rows="5"
rowSelection="multiple"
value="#{pageFlowScope.editNotificationBackingBean.ingredients}"
binding="#{pageFlowScope.editNotificationBackingBean.ingredientsTable}"
autoHeightRows="10" id="t2">
<af:clientListener method="goEditRow" type="dblClick"/>
<af:serverListener type="doubleClickOnRow" method="#{pageFlowScope.editNotificationBackingBean.handleRequestIngredientsSelectBtn_action}"/>
<af:column headerText="#{bundle.col_fr_name}" width="240"
sortable="true" sortProperty="name.FR_Description" id="c1">
<af:outputText value="#{row.name.texts['fr'].value}" id="ot1"/>
</af:column>
In my backing bean i call this method to remove selected elements :
public void unselectBtn_action(ActionEvent actionEvent) {
RowKeySet rowKeySet = selectIngredientsTable.getSelectedRowKeys();
int i = 0;
Iterator it = rowKeySet.iterator();
while (it.hasNext()) {
Integer index = (Integer)it.next() - i;
selectIngredientsTable.setRowKey(index);
CompositionIngredient compositionIngredient =
(CompositionIngredient)selectIngredientsTable.getRowData();
notification.getProductDetail().getCompositionIngredients().remove(compositionIngredient);
i++;
selectIngredientsTable.getSelectedRowKeys().clear();
AdfFacesContext.getCurrentInstance().addPartialTarget(selectIngredientsTable);
Thanks in advance.

I have made a mistake, i don't paste the right <af:table> from my jspx.
Here is the correct one :
<af:table var="row" rowBandingInterval="1" width="1050"
rowSelection="multiple" id="tableSelectedIngredients"
value="#{pageFlowScope.editNotificationBackingBean.notification.productDetail.compositionIngredients}"
binding="#{pageFlowScope.editNotificationBackingBean.selectIngredientsTable}"
partialTriggers="::tab_ingredients_list_expressed_per">
<af:column sortable="true" headerText="#{bundle.col_name}" id="c5" width="180"
sortProperty="ingredient.name.FR_Description">
<af:outputText value="#{row.ingredient.name.texts['fr'].value}"
id="ot18"/>

Removing Audio From Video (Problem 2) !!!HELP!!!

I have succesfully managed to remove audio and add new audio to an (avi) video. However, when I tried to do the same thing with an new (mpeg) video/ soundtrack. Logic did not allow me to extract audio from video or give me the option to de-select audio tracks when bouncing. So when I extract video with audio I get the old audio track plus the new audio combined. Is it do with the video format? can I convert video formats in logic? many thanks, Ben.

open in quicktime, then click save as and save as a .mov file. This should work. Not sure why this is happening though. Let me know if this works...
Please remember the helpful and solved problem....

Remove element from GUI

Hi guys,
I am adding elements to the gui like this:
var myText = win.add("edittext", undefined, "whatever");
Later in my code I need to remove this element from UI. Is it possible?

Use the remove() method: win.remove(myText);
In general: container.remove(child);
You can add it later later but then, if you use the autolayout, you'll need to relayout: win.layout.layout(true) otherwise it won't show up

Removing Objects from Video

I have a video of a cat dancing. I would like to remove the arms of the person making her dance, so it looks like she's dancing on her own.
I'm pretty sure I have to use After Effects for this? Would this be considered rotoscope? Any advice for this would be greatly appreciated.
Thanks a bunch
P.s. I have included the video in question.

Here's a fun look at how rotoscoping has been done in AE over the years...
http://tv.adobe.com/watch/ae-me/the-history-and-future-of-rotoscoping-in-after-effects/
And a free (home-made) you-tube tutorial demo:
http://www.youtube.com/watch?v=ZXlN14wyThQ
Linda.com and some other sites have much more in-depth lessons, but you have to pay for most of the good ones.
It's going to ba lot of work in any case. I did about a second-worth of rotoscoping in a personal project recently and it took me several hours to get it right. So perhaps ask yourself, "Does the world really need a nother dancing cat video?"
Seriously, anything is fine to learn with if the subject intersts you. If you really want to do a dancing cat video, play with that one a little to get the feel of it then re-shoot it in a way that will make it easier to complete, for example:
1. Shoot with a fixed camera so that you don't have to worry about camera movement in addition to the cat and your hands.
2. Shoot a seperate shot of just the background so that you can matte it in from behind (or in front) as needed.
3. Maybe wear green gloves and shoot over a green backgorund (or some other distinct solid color) and just try keying things out and animating the gaps back in with sperate images/video clips. Keying usually doesn't look as good as rotoscoping though.
4. Got any cat-colored gloves? Maybe some white gloves painted to look like cat fur? Then all you have to take out is your arms beyond the cat's body.
I know some of those ideas sound cheesy and far-fetched, but that's how movie magic was invented in the first place. It's just that now there are many really experienced creativeswith a century+ of advancements, some really high end tools (like proprietary CGI software and render farms), and lots of time and manpower that you probably don't have... so they make it look easy. But if you don't mind the end result looking a less than broadcast-perfect, you can probably get the point across, learn a lot, and have some fun in the process.

Need to remove movie from video list

Hi, I imported a movie into my iTUnes 6 video list and I want to remove it. I put it up there as a test and I even deleted the file but the thumbnail is still up there on teh screen with my other videos. THis isnt a major deal but jsut kind of annoying.
I tried right-clicking and going up to the menu but i saw nothing abotu removing. Cut was grayed out so it wasnt an option. Is there a setting i need to change to give me manual control or something?
Thanks.

I'm having the same problem. I had some old Rocketboom.com videos on my hard drive that I didn't know I had. When I updated to iTunes 6.0 it added these videos to my iTunes library. The problem is that the files had a read-only attribute set. Windows/XP OS. Since the files have read-only permission, iTunes won't allow me to delete the files. So I deleted the videos manually from the OS, unfortunately iTunes still won't let me delete the video from iTunes, even though the videos no longer exist. UGH! iTunes does ask me if I want to "browse" and find the file. I tried pointing the library to a file that was deleteable, but iTunes still thinks the file is protected and won't let me delete the file. I'm stumped. I can't think of way to delete all these files from my iTunes video library. We may have to wait for the next update. I hope it's not too long in coming.
