JPEG2000 rendering - How to?

Hello,
I am trying to render a project directly to a JPEG2000 sequence but currently it requires 10 diffrent steps in order to get the needed JPEG2000 variant.
First, I reneder out a TIFF-sequence, then changing the colordepth with a OpenSource converter. From there, I use the converted TIFF's to make JPEG2000 with ANOTHER OpenSource converter - this is to meet the requirements of Dolby Digital Cinema equipment with a DCP Packaging.
Is there an easier way to achieve this? Is there a JPEG2000 codec or plugin-converter for After Effects or Premiere?

CS5 renders DCI compliant J2K in the default XYZ color space and the logarithmic DPX space, if I remember correctly. Otherwise I'm not aware of any way to do this directly, but even the info regarding CS5 should be taken carefully, as I don't do digital cinema stuff and never have actually used it....

TableSorter + custom cell renderer: how to get DISPLAYED value?

Hi!
I have a JTable with a custom cell renderer. This renderer translates numerical codes, which are stored in the table model, into textual names. E.g. the table model stores country codes, the renderer displays the name of the country.
Now, having a reference on the JTable, how can I get the DISPLAYED value, i.e. the country name? Is there some method like ....getRenderer().getText()?
Thanx,
Thilo

Well, a renderer can be anything. It may be rendering an image not text so you can't assume a method like getText(). However, since you know the component being used to render the cell you should be able to do something like:
TableCellRenderer renderer = table.getCellRenderer(row, column);
Component component = table.prepareRenderer(renderer, row, column);
Now you can cast the component and use get text.
Another option would be to store a custom class on the table cell. This class would contain both the code and value. The toString() method would return the value. Whenever you want the code you would use the table.getValueAt(...) method and then use the classes getCode() method. Using this approach you would not need a custom renderer. This thread shows how you can use this approach using a JComboBox, but the concept is the same for JTable as well:

Premiere Elements 12 has stopped rendering, how do I reactivate.

Premiere elements 12 has stopped rendering my work. How do I reactivate the feature?

GautamBahl
Where are you getting your information on
Try to recreate the preferences for premiere elements
and using the following path to do that.
For windows C:\Users\Usename\AppData\Roaming\Adobe\Premiere Elements 12.0
You are the second one today who seems to be off the path. Either that, or you know of a new approach to "resetting the preference for premiere elements" using the the Logs Folder and Trace Dalabase.txt file in the 12.0 folder in the Premiere Elements 12.0 Folder.
The path that I find is
C:\Users\Owner\AppData\Roaming\Adobe\Premiere Elements\12.0
and in the 12.0 Folder is the following
Windows 7, 8, or 8.1 64 bit
Here you have the Adobe Premiere Elements Prefs file that you can delete. And, if that does not work, you can delete the whole Premiere Elements Folder in which the 12.0 Folder exists.
The Adobe Folder in the above path also contains a Premiere Elements 12.0 Folder which contains a 12 Folder. This particular 12 Folder contents look like this
Even Adobe documentation seem to acknowledge the way to the "preferences" that we are.
http://helpx.adobe.com/photoshop-elements/kb/preference-file-locations-photoshop-elements. html#main_Premiere_Elements_preferences_
even though the document cites an earlier version than 12.
But, I have actually looked at the computer files for Premiere Elements 4 through 12 and see what I am reporting. Have you checked these computer files first hand?
If I am misinterpreting what you and the other person today are posting here, please accept my apologizes but explain the rationale behind your approach.
Thank you.

JTree cell renderer: how to fill whole row?

hi,
i'm trying to make a tree cell renderer that renders at default height, but fills the horizontal width of the tree (e.g. with a JLabel with a custom background color). I'm working on the theory that in order to do this you need to change the preferred size of the component used to stamp the image at render time.
The problem is that the preferred width then needs to be set to a value that depends on the context of the particular node (e.g. a deeply nested child node will be further to the right than the root node).
I can't seem to find a method to say where the rendering starts though - does anyone know a way?
(also if not then would setting the width to some astronimcal value break anything?)
thanks,
asjf

Try this one, it will higlight the background and foreground colors of entire rows.

Recording to cassette with no rendering: how to?

Hi.
I rendered my hdv holiday 33 minutes trip on Premiere selectecting "export to cassette" and it took about 6 hours to. Finally the camera started recording but suddenly it stopped (don't know why). I have the Premiere generated file, *.hdv on my hard disk and would like to know whether there's a way to record the file to cassette with no rendering the project again.
I hope I've explained the question fine and hope there's a way, or a standalone program (if Premiere isn't able to) to put my rendered project into the cassette avoiding to wait for 6 hours again.
Thank you very much.
Michele.

Ah ok. I had the thought I was doing something wrong but he fact is that.
Steven, you probably know that Premiere generates a file while rendering the sequence and the put it into the tape. Is there a way I can put that file into the tape with Premiere or another software? I need a simple drag and drop from pc to tape. I need a software like hdvsplit that the generated hdv file into the tape throgh the firewire port.
Thanks a lot.

I've created a key frame effect in FCP but it dissapears along with the moving object in my layer after rendering, how do I fix this?

I'm creating a titles sequence with Final Cut Pro. In two instances I've put an object in the time line and moved it using keyframes and motion. Before I render the file is still on the layer and visible while scanning the footage with the playhead. However as soon as I render the file dissapears while playing. The object is still listed on the timeline, but is basically invisible when I play the rendered footage. This has happened twice on my timeline. I wish I could explain this any better, but to be honest I've never seen this before and I have no better way to describe it. Other than my object just simply disappears after I render it. Hope you can help. Thank you.

You want your scratch disk to be set externally to a drive with a minimum of a FW800 connection. Is that what you have? (I understand you moved it during the troubleshooting process)
You haven't turned off Clip Enable have you? Right click the text file and make sure Clip Enable is checked. Or have you disabled the track with the green button to the left on the track?
I can't say I've seen this behavior from FCP. Maybe someone else has and they can shed some light on the situation.
I wouldn't use HQ even for a Canon 5D. I use ProRes(LT) RED or Arri Alexa now we talking big sensors that would take advantage of HQ. Assuming that the project will be exhibited on a system that would show you the differences.

Suddenly my PS CS5 defaulted its "Save As" to JPEG2000, how do I restore it back to "Save As" JPEG?

I got a new computer (Windows 7) at work this April and as of today, when I work on any of my JPEG images in PS CS5, suddenly it has defaulted its "Save As" to JPEG2000. How did this default change and how do I get it to default save as. JPEG again? There was nothing I noticed and no warning as to why this has changed, I didn't touch a thing!
(Last week, Adobe had to work with our IT manager to fix a problem that started occuring with my new Adobe Acrobat Pro 11 program. They had to log into my computer and change a registry thing to get it to work properly again...also something that changed without warning!!)

Thank you Curt Y, as I saw your post reply come through, I had just hung up with Adobe support (after being on the phone for an hour & a half).
To be clear...prior to today, if I opened a JPG file, and did an immediate "save/save as", it would automatically re-save as a JPG file but it seemed to suddenly be defaulting to a "save/save as" JPEG2000.
They claimed that yes, there was a fix for this and while I was on hold she had me follow a few directions which DID fix the issue. While we were on the phone she was able to have me restore it to at least a default "save/save as" for a PSD file rather than a JPEG2000, which is better than nothing and she was about to help me get the default set so that when I open a JPG it would automatically default to "save/save as" a JPG, but she couldn't get it that to work. After she logged on to my computer to physically do it herself and failed to fix it further, she thinks my security permissions (we are on a network) are not set properly and she wanted to create a new user account with the proper permissions but we were halted because our IT guy is not in right now.
She gave me a case# and when he returns tomorrow, we are to try her list of instructions starting with creating a new (PS CS5 user account) then if that does not restore the "save as" defaults we are to uninstall, then re-install PS. If this still does not work we are to call her back and they will try to fix it from there. She did tell me that in my version of PS (CS5), she was able to open a JPG (on her end), then hit save as, and it defaults to saving as a JPG, not a PSD as is happening to me.
Before I posted here, I did do an iternet search to find out how to set the defaults, however I too found that everyone says there is no such default of a "save as" JPG...but Adobe claims otherwise. We shall see what happens tomorrow...

How to remove a cell renderer

I have been looking through the apis and search but to no sucess. I have tried a few different remove methods but none seem to be working. Does anyone know how to remove a cell renderer.

What do you mean "remove a cell renderer".
What component or class are you talking about? I'm only aware of renderers being used by Swing components. If thats the case then the question should be posted in the Swing forum.
What do you mean by remove? If you remove the renderer how would the cell be renderered. Do you mean that you want the cell to use the default cell renderer?
What component are you talking about? I'm aware of renderers for JTree, JTable, JList, JComboBox.
If I had to guess I would think you are talking about a JTable, so I would suggest simple setting the renderer to null for the particular column.
If that doesn't work then you can always use the getDefaultRenderer(...) method and then reset the column that way?
But you question is not very clear so Its a lot of guess work on my part.

How do I create data-driven linkbuttons whose visibility is controlled from the front end?

I've made a component based on a mx:TitleWindow that contains linkbuttons that I'm using as a context-menu.
The TitleWindow component contains link buttons like this:
[Bindable]
private var _showEmailThis:Boolean = false;
[Bindable]
private var _showApproveThis:Boolean = false;
[Bindable]
private var _showReviewThis:Boolean = false;
<mx:LinkButton id="lnkEmailThis"
               visible="{_showEmailThis}"
               includeInLayout="{_showEmailThis}"
               click="lnkEmailThis_click()"
               label="Email this!" />
<mx:LinkButton id="lnkApproveThis"
               visible="{_showApproveThis}"
               includeInLayout="{_showApproveThis}"
               click="lnkApproveThis_click()"
               label="Approve this!" />
<mx:LinkButton id="lnkReviewThis"
               visible="{_showReviewThis}"
               includeInLayout="{_showReviewThis}"
               click="lnkReviewThis_click()"
               label="Review this!" />
This component contains a large number of links and is re-used by multiple modules in the same application.
Within each module, this component is used when a user clicks on a row in a datagrid.
The code looks like this:
In "Requests" module:
private function dgRequests_click(event:MouseEvent):void
    menu.showApproveThis = true;
    menu.showReviewThis = true;
In "Performance" module:
private function dgPerformance_click(event:MouseEvent):void
    menu.showEmailThis = true;
    menu.showReviewThis = true;
As you can see, the visibility of individual linkbuttons is controlled within each module by setting boolean properties.
If I alter this component to use a renderer, how can I control the visibility of the linkbuttons from the code in each module (there are over a hundred links with different functionality - not every link will be used in each module)? Note: it is not known from the back-end which grid within which module uses which link. This is set in the front end within each module's actionscript file.
e.g., if the XML looks like this:
<links>
   <link>
      <label>Email This</label>
      <visible>_showEmailThis</visible>
   </link>
   <link>
      <label>Approve This</label>
      <visible>_showApproveThis</visible>
   </link>
   <link>
      <label>Review This</label>
      <visible>_showReviewThis</visible>
   </link>
</links>
and I set the Email link to show in the module like this:
private function dgPerformance_click(event:MouseEvent):void
    menu.showEmailThis = true;
How do I make it take effect? Is there a way to control the visibility of a linkbutton within an item renderer in a component from the module that uses that component? Is there something like reflection in the Flex framework?

Put a single frame sequence structure around your stop button and then wire from the error cluster going into the error handler to the edge of the sequence structure. Now your code will stop at the end of the current iteration. To see why this works, watch you code execute with execution highlighting turned on and review the section of the manual talking about "Dataflow".

How to set the first row as selected in single selection of table

when the page renders how do we make the first row as selected for single selection in a table.
Thansk a lot for your help

set the selection Attribute's value to 'Y' for the first row. Thats enough.
eg;
Row row=vo.first();
row.setAttribute("SelectionAttribute", "Y");

Passing a parameter to a Item Renderer

I have a dataGrid with about 12 columns. I want to render an
image in each cell based on the value of that node. Problem is: I
need the renderer to know what node to evaluate.
<mx:DataGridColumn width="20"
itemRenderer="com.apts247.www.renderers.Test" paddingLeft="0"
color="#990000"/>
<mx:DataGridColumn width="20"
itemRenderer="com.apts247.www.renderers.Test" paddingLeft="0"
color="#990000"/>
When these hit the item renderer, how can i make it know what
data to evaluate. I want to pass it, for example, "task_0", or
"task_1"

If the Itemrenderer implements the IDropInListItemRenderer
interface, you have access to the listData property which contains
information like column index and dataField.

Rendering - What Does That Mean?

There are often questions regarding the process of Rendering, for smoothest playback of the Timeline. The need to Render, for the smoothest possible playback is indicated by colored bars, just below the Timeline Ruler - red bars/lines, green bars/lines and in PrPro, yellow bars/lines. With the exception of the yellow bars/lines, it's the same for either PrPro, or PrE. This ARTICLE goes into more detail. Though Todd and Steve created it for PrPro, with the exception of the yellow bars/lines, it's the same in either program.
Hope that this explains Rendering, how and why it's useful and how to tell if your source footage needs it, for smoothest playback.
Depending on what one has in their Timeline, what they are doing with it, and how critically they need to see it in playback, one might never really need to Render, or they might need to Render small segments many, many times, as they make adjustments.
Good luck, and thanks to Todd and Steve!
Hunt

Here is a look at the red and green lines in the Timeline, plus the WAB (Work Area Bar) that can be set to limit the area of the Timeline, that is Rendered:
This is from PrPro 2.0
This is from PrElements 4.0.
The WAB will be almost identical in later versions of PrPro and PrE.
Hope that this helps,
Hunt

How to set JTree lines invisible?

Hi all,
I have tried it with adding following code while GUI is initializing.
here i'm using a custom TreeCellRenderer. But still line are visible :(
MyTreeCellRenderer renderer = new MyTreeCellRenderer();
renderer.setBackgroundSelectionColor(new Color(0xffffff));
renderer.putClientProperty("JTree.lineStyle", "None");
setCellRenderer(renderer);How to get the thing done correctly?
kaushalya

This client property should be set to the tree, not the renderer.
Anyway it will only work in Java look and feel (Metal).
Read the tutorial: [Customizing a Tree's Display|http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html#display]

Rendering only specific portion of timeline

If you have items throught the timeline that require rendering,
how do you get it to render only one portion? Using In and out points
around that area doesn't appear to work.

No probs!
as you probably know if you go to main menu>Sequence>Render only you have a range of alternative rendering options depending what you want to render and how your timeline is set (ST or RT)

Provide alternative JSON renderer? Without losing default JSON renderer?

REQUIREMENT
Construct some custom JSON rendition of a page. For example: /content/site/page.my.json
And we want to accomplish this without losing the out-of-the-box functionality:
/content/site/page.html - WORKS OUT OF THE BOX
/content/site/page.json - WORKS OUT OF THE BOX
WHAT WE'VE TRIED
We've added a jsp to our global page template and named it my.json.jsp. This has given us this behavior:
/content/site/page.my.json - INVALID RECURSION SELECTOR (the request gets handled by default json renderer and "my" is not a valid recursion selector)
/content/site/page/_jcr_content.my.json - WORKS (we can see our custom json renderer working), but we have other reasons we cannot use this URI.
So we're nearly there. Next, we add "json" to the list of extensions that are treated with default resolution behavior, by going to felix config and editing the "Apache Sling Servlet/Script Resolver And Error Handler:
By doing this, now our custom json WORKS, but we get the following results:
/content/site/page.my.json - WORKS (our custom JSON renders)
/content/site/page.json - DOESN'T WORK (html is rendered rather than the default JSON renderer)
How can we provide this custom renderer at *.my.json without losing the functionality of the default *.json renderer, necessary for dialogs in the page properties, etc.
Thanks!

Assuming your are using OOB page component.
After adding a jsp to our global page template and named it my.json.jsp.
In order for [0] to work create a file at [1] having contents [2]. I would advise to overlay at /apps instead of modifying at /libs. Please refer sling url-to-script-resolution and our training material for more details.
