Rendering utilisation change

Hi all,
I have been using AE for many years now, largely for TV work, but recently I have been doing more feature work.
When starting a render, I have noticed the machine is quiet, chugging along, tearing through the render at a decent clip. Coming back an hour or so later, I can hear the machine's hard drive going nuts and the render speed significantly slower, with the "Estimated Remain" figure significantly higher than originally estimated. I've noticed this consistently regardless of whether the content being rendered is multi-layered comps with numerous various elements and effects, or if it is just reprocessing numbered DPX frames. I have also noticed this happens regardless of whether I am rendering to a Quicktime movie or numbered frames in DPX or TIFF format.
My machine is a MacPro, with 2 x 2.93GHz Quad-Core Intel Xeon, 8Tb internal HDD, 32Gb 1066 MHz DDR3 RAM, running OSX Lion 10.7.2, Adobe After Effects CS5 (10.0.2.4), which has memory set to multiple processor rendering.
I have juggled RAM allocations to other apps (even though the only other thing running is the OS - everything else is off), juggled the number of processors that AE is to use, and numerous other memory and cache settings, but consistently AE at some point into these renders decides using RAM isn't the thing to do any more and chooses instead to use the hard drives. I would have thought 32Gb of RAM would have been a good amount for AE, but I get the decided impression it has rarely employed it.
I read there's a default usage of 2Gb RAM, but this has been upped in AECS5.5 to 20Gb, so that may solve the problem, true, but until I can upgrade, I'm wondering if this problem might be something else.
Any experienced wisdom is welcome.

Here's a link to the FAQ entry that Szalam mentioned:

It sounds like you're swapping the contents of RAM to the disk. That is a performance killer. The FAQ entry has a link to a post by me about that. The gist is to leave plenty of RAM for the OS and other software.

"Rendering: settings changed" after saving changes from Bridge

I have LR 2.6 on my Mac. I import RAW images through LR, let LR build 1:1 previews. Once the import has finished & previews are built, LR moves from image to image fine. I then do my basic edits, deletions, and do a batch renumber.
Next I go to Bridge to make my adjustments in the RAW window without opening the files. I go back to LR, save the changes, allowing the Bridge changes to overwrite the LR development import presets in the xmp files.
It usually takes LR a while to save all the changes, but eventually it does it. However, here is my issue. No matter how much time I give LR to render new previews, I don't think it does, at least not until I go to Library mode double click an image to view larger (to fit the window). When I go from image to image, it takes a few seconds while displaying the message "Rendering: settings changed..." Now, this is not necessarily right after I save the changes, but it still happens weeks later- whenever I go to view those images. Does LR not automatically re-render the previews after development changes have been made and saved to LR?
And if not, how would I force LR to do it for that catalog, or for all my images?
Thanks,
R

A fair question- one, when I have tried, LR is way slower on my Mac G5 than doing it in Bridge, which is slow itself. I just launched LR, had an open folder with 303 images in it which I had already rendered previews of, then clicked on Develop module- it took 13 seconds to go to that module & finish "loading". Yes, a new commuter would solve many problems <g>, but until then....
What you may need is more RAM. Or do you have other applications working in the background 13 seconds to build a preview!!!!! Using a old Macbook with 1.2 GB RAM an it does it faster than that!LR doesn't require a lot of power from a machine...it does need as much RAM as you can stick in a machine and the fastest disks you can use...but if it is taking 13 seconds to build a single preview then it isn't really worth using IMO
Why not make all you RAW adjustments in Lightroom Develop module. The raw processing engine is the same as ACR and you can choose "auto save changes to xmp" in the preferences.
Ah, bingo. That works, abet slowly (see above). Okay, I will just have to remember to manually do that once I save changes to LR from xmp data. I guess I thought LR would be smart enugh to do that itself, but I guess not. And again, I find it faster to go back & forths, even with an extra step.
LR can be set to automatically write any changes to xmp, it doesn't have to be done manually (set this in preferences) you just have the choice. It won't read changes made in other applications automatically as this would be a very bad idea..it would after all over write the LR database. So if you do want to over write the LR database you must activly choose to do so.

Rendering: Settings Changed

I don't remember ever seeing this message before, but since I've upgrade to LR 1.4.1 I keep seeing the message "Rendering: Settings Changed" the first time I view an image in "Fit". Also when I zoom to 1:1, I get the message "Rendering: Higher Quality", which I also don't recall seeing before. I've tried rerendering previews both standard size and 1:1, but it doesn't seem to have any effect. Does anyone know what these message mean, and I why I am getting them now? It definitely slows down my rating workflow.
It also seems curious that after I did Discard 1:1 Previews (it claimed it was discarding several hundred of them), when I did Render 1:1 Previews: it claimed to only need to create 30 of them. Shouldn't it need to render all the previews that is discarded?

It will only render previews for the photos that you have selected.

Rendering problem, changes do not show up after rendering?

I am new to this and can not figure out why the end result after rendering only shows the "original" movie clip, none of the editing i have done are showing up? when i scrub through the composition everything works fine? I have tried both the ordinary render queue in AE and Adobe media encoder.

Yeah I think I got it right with the rendering queue, however I saw something now that may have something to do with the problem, my corrections is visible when I have "fast draft" chosen under the "fast previews" button, when i change to "off (final quality" the effect disappears? I thought the choices under that button just is what it says, for fast previews?
I attach the screenshots you where asking for.

Font rendering suddenly changed

I have a problem with the rendering of aquafont. I've been using the font for quite awhile, and suddenly the rendering inside of urxvt changed. See the following screenshots: Original and Current
The spacing in particular has changed. I am running current/extra/community, fully up to date. I recently installed gnomebaker, and with it, a bunch of gnome deps. After rebooting is when the problem started. I've since removed gnomebaker and all the deps, rebooted, but the problem persists. I don't think gnomebaker has anything to do with this, I'm just trying to give all info that might be relevant.
Other fonts seem to be unaffected. I am using aquafont in conky and it seems fine there too.
I have no idea where to go from here. Any help is appreciated. Let me know if you need additional info. Thanks.

Alright, I've figured out what is causing this: setting
export LC_ALL="en_US.iso-8859-1"
in ~/.bashrc
Commenting this line out and reverting to UTF-8 returns the font spacing to the correct size. The reason I added this line was to fix a font issue with perldoc where some characters were not available. For example, try "perldoc -f print"
Is it possible to use perldoc in a UTF-8 environment?

Can't change displayed properties in resource renderer

Hello everybody!
I'm trying to do display a very simple list of filenames in a KM navigation iView. I've assigned a layout set, which references a collection renderer and a resource renderer. In the resource renderer, "Visible Properties" is set to rnd:displayname(contentlink).
But still I get a list with filename, file size and timestamp. No matter what I put in the "Visible Properties" field, the same thing is displayed.
I've verified that the layout set references the correct resource renderer by changing other attributes ("Command Display", for instance), and these changes do have an effect.
Any ideas what might be the problem here?
One more thing. This iView is a dynamic navigation iView. How can I make the documents open in the content area of the portal instead of in a new window?
Any help is very much appreciated.

Hi Martin,
seems like you have selected a collection renderer for "structured output", like the grid or tree collection renderer. In this case the collection renderer is the one who is responsible of the properties displayed.
So what you have to do is edit the parameter "Displayed Properties" of your collection renderer with the properties you want to display.
Check this <a href="https://forums.sdn.sap.com/thread.jspa?threadID=28751">link</a> for more info about "unstructured vs. structure coll. renderers".
Hope this helps,
Robert
PS: The iView Property "Launch in New Window" should be set to "Display in Portal Content Area", in order have the iView displayed as you wish.

How to change Rendering Extension in sql server Reporting Services based on User Permissions

Hi,
I want to provide SQL server reporting services rendering extension based on user Access.
For Example
User1 can have options of Rendering to EXCEL and PDF
User2 can have a option of CSV
i read one article which is useful for report basis rendering extension changes. but i want to give user basis rendering options.

You can use a data driven subscription for that
Maintain a table with rendering extension information for various users ie their AD user login. Then setup a data driven subscription based on table values
You will be creating a dataset with query for retrieving userid as well as rendering extensions and then just set the value as Get value from database for render Format and To properties
For more details refer

Using footage from my iPhone 4, how can I remove the black bars on the sides of my picture? Or change the color to white...

My footage is vertical and there are two black bars on the side filling in the rest of the picture. I want to imbed this into PowerPoint without the black bars on the side. Any suggestions on how I can remove them or at least change the color to white? I changed the background color in View > Background > White, but it was only for editing purposes and didn't keep the color after rendering.

To change the background to white, in FCE, place the video on track V2 and place a color matte generator on track V1. The default color for the color matte is grey so you'll need to change it to white using the color picker.

How Come Some Clips Need To Be Rendered

Hi,
I have several projects open, one is from standard def DV tapes and the other is from a FCP learning tutorial. When doing 3 way color correcting the project from the DV tapes needs to be rendered after changes while the tutorial files don't need rendering. I looked at the source file types for both and they are Quicktime movies. Why does one need rendering?
Thanks in advance.

Quicktime is just a wrapper that contains many many CODECS. What is the codec of the tutorial footage? If you mix the formats on the timeline, one format won't require rendering, where the format that is different will.

Adobe Premiere CC 2014.2: losing rendered files when using warp stabilizer

Hi,
I am constantly losing rendered files when using the warp stabilizer. So far I have tried about every hint I could find on the web such as cleaning the cache, rebuilding the rendered files, creating additional sequences etc etc.
Honestly I am getting tired of using a product that isnt cheap in the first place to rent and where a bug like this apparently persists over several product versions without being fully fixed (I have had this problem throughout 2014 but according to forum postings others seem to have problems with much earlier versions as well).
I would be really grateful if somebofy has any suggestion how this can be addressed.
I am also happy to help testing fixes - if there are any fixes available.
Thanks a lot and Happy New Year!
Martin

Hi Catherine,
Welcome to the Adobe forums.
Please try the steps mentioned below and check if it works for you.
1. Launch Premiere Pro and create a Project, go to File menu>Project Settings>Renderer and change the Renderer to Software only mode, delete previews if you get a prompt and then try to import the clip.
2. If step 1 fails or the Renderer is already on Software only mode, go to Start Menu and search for Device Manager, go into Display Adapters and Right click on the Graphics card to select Update driver software option, on the next screen choose "Browse my computer for driver software", then choose "Let me Pick from a list..." option and from the list select "Standard VGA Graphics adapters. You might need to change the screen resolution of your screen and once done restart the machine again.
Launch Premiere Pro and import the clip to check.
Regards,
Vinay

Can Line Chart charts base renderer by category

I have done some Googling on this, but frankly I'm not sure
what to even search for. Here is what my boss wants:
A month by month chart of sales showing revenue trends as
well as projections for then next two months. He wants a solid line
for actual data in existing months which turns into a dotted line
with projection data for future months.
I have downloaded and played with the code from quietly
scheming (
http://www.quietlyscheming.com/blog/charts/dashed-lines/)
but it seems to apply to the entire line.
I'm not sure if the direction I should be taking is two
different line renders based on the category axis, or a way to make
the renderer smart enough to change the line at the appropriate
time.
Thoughts please?
Thanks.

I'm still playing with this solution, but for what it's worth
this is what I am doing:
I downloaded the source from quietly scheming for the dashed
line renderer. (
http://www.quietlyscheming.com/blog/charts/dashed-lines/)
I changed the DashedLineSeries to a ProjectionLineSeries and
changed the DashedLineRenderer to be ProjectionLineRenderer. Then
in the renderer, I changed the updateDisplayList method to loop
over the LineSeriesItems (_lineSegment.items array) and find where
past meets future. Note: in doing this, I made an assumption that
your xValue would be a date to use this series. I then used a
combination of the drawPolyLine and drawDashedPolyLine methods from
their respective graphics utility classes to draw the applicable
portions of the line.
Here is the contents of the
ProjectionLineRenderer.updateDisplayList method as I have it now.
override protected function
updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
var stroke:IStroke = getStyle("lineStroke");
var form:String = getStyle("form");
var pattern:Array = getStyle("dashingPattern");
pattern = (pattern == null) ? _pattern : pattern;
graphics.clear();
var current_date:Date = new Date();
var beginning_of_month:Date = new
Date(current_date.getMonth(),1,current_date.getFullYear());
var projected_items:Array = new Array();
// Loop over the lineseriesitems
for(var i:int = 1;i<_lineSegment.items.length;i++)
// Grab the items whose dates are in the future
if(LineSeriesItem(_lineSegment.items
).xValue = beginning_of_month)
// If this is the first item that is in the future, back
// up and grab the previous one so our dotted has a starting
point
if(projected_items.length == 0 && i > 0)
projected_items.push(_lineSegment.items[i-1]);
// Add the future data points into the projected array
projected_items.push(_lineSegment.items);
// Draw the solid portion of the line. Notice the end point
is the size of the entire array, minus the future points.
// Adjusted by two because they overlap one point and the
array starts at 0.
GraphicsUtilities.drawPolyLine(graphics,_lineSegment.items,_lineSegment.start,_lineSegmen t.end,"x","y",stroke,form);
// Draw the dashed portion with the projected_items array
DashedGraphicUtilities.drawDashedPolyLine(graphics, stroke,
pattern, projected_items);
Technically, I am also assuming that the last data point is
the current month, and therefore the projected one. Based on that,
the date math is probably unnecessary, but maybe I'll change that
later.

Timeline Changes don't apply

Recently I've come across an issue I've never seen before. I drop a clip into a video track, trim it, change opacity fades and render - works fine.
Then I tweak the opacity, filters etc., but the render bar doesn't turn orange and my changes won't preview. It still plays back the last rendered version, and any re-rendering or changes won't apply.
I have to delete the clip, bring it back into the track, and re-render.
What is up?

Might simply trash your render files. The tool to do this is in the tools menu.
Does this happen with every new sequence in every new project now? or?
What format are you editing, and post the OS, Version of QT and Version of FCP you're running on which Mac?

Programmatically selecting hovered state of item renderer - Greg pleeease

I'm a bit new to Flex, so I have the idea but can't get it to work.
I'm using an item renderer that takes its data from an HTTPService
    <s:SkinnableDataContainer
                              dataProvider="{boData}"
                              itemRenderer="extras.BoItemRenderer"
                              skinClass="extras.BoSkin" />
the boData data provider is an ArrayCollection not an Array
In my <s:ItemRenderer ...... > (BoItemRenderer.mxml) I have
- 2 states: normal and hovered (each has different style, which I will leave out to keep things simple)
- and the data is presented as follows:
    <s:HGroup>
        <s:Label text="{data.idNum}" />
        <s:Label text="{data.firstName}" />
        <s:Label text="{data.lastName}" />
    </s:HGroup>
Naturally as I hover on any row in the item renderer, it changes to the hovered state styling, all done by flex.
What I want to do however is programmatically induce that hover state without actually hovering.
For example, given a hard-coded idNum, I need to programmatically set the state of that row to hovered.
My approach is as follows, but not sure how to target that specific item,
- search the dataProvider to find the index of the row with idNum that matches my hard-coded value. I looked at the documentation, and there is indexOf, but it's for Array and not ArrayCollection.. also not sure how that works since I'd like to read the data from the item renderer directly, not from the original data provider.
- then I would find that index in the itemrenderer and set the state of that index to hovered.
Simpler said then done, but I'm stuck on it...
Thanks,
David

Depending on what is it the ArrayCollection, in theory you might be able to do this:
var myIndex:uint;
for(var a:uint=0;a<myCollection.length;a++){
    if(myCollection.getItemAt(a).idNum == myHardCodedIdNum){
        myIndex = a;
        break;
You can programmatically simulate a hover over by having the component manually dispatch a mouseOver event, but this is not the way to do it with itemRenderers.
Item renderers can be tricky, particularly if they are being used in List based controls, like List, DataGrid, TileList, etc. because the itemRenderers are recycled.
With that in mind, and with your somewhat non-typical situation (manually simulating hover over), I might be wrong on this, but it might be best to control this via the dataProvider data. So have a field named currState, and somehow make the renderer automatically change its state if that data field changes, then you simply programmatically change the currState data field for the desired item.
As far as how to change the state of the item renderer based on changes to a data field, maybe ChangeWatcher?

Intermediate rendering on CS4

A week ago I started my first project on CS4 with one 2-hr raw material imported from the card. (I am rather experinced on Premiere 6.5.) Today I finished a rough draft, which is 1 hr long and contains more than 600 clips. It is incovenient to work with so large project, and I'd like first to render it to 3-5 pieces, then to work with every piece (as it were the original one) separately: to cut it, to add transitions, music, speech etc. How can I make this intermediate rendering without changing the format?

This is a question you probably want to ask on the Premiere Pro forum.
This forum is specifically for Creative Suite (as a whole) issues.
Good luck!

Changing the color of text in the DataGrid cell conditionally

I am using a DataGrid in my application and my requirement is
to change format and style of data value in the DataGridColumn per
below:
If the data value is a negative number
1. change the color of a value to red
2. remove the '-'ive sign
3. include the value between in parenthesis.
I was able to accomplish 2 & 3 in the labelFunction for
the DataGridColumn. But have been struggling to accomplish (1)
within the label function.
Can this be done in the labelFunction? I am using Flex 2.0.1.
Appreciate any help with this.
Thanks.

you'd probably best use an item renderer to change the color.
have a look at
background
color in item renderers on
alex's flex closet for an
example of this.
