Rendering VS Previews?

I have noticed when I do my RT previews the task managers shows both CPU cores working but when I render to a file for CD-ROM use only one of the cores is working. I have Premiere Pro 1.0. Is it any different in PP CS3?

Thanks for your reply. So you are PP CS3 will use all the cores (quad core) when rendering and during RT previews. IS this correct?

LR 5.0 slowly in rendering import previews (RAW/Canon 6D)

Hi guys,
does anybody know s.th. about slow rendering imagepreviews in the import dialogue?
My LR 5 is as slow as a snail generating those previews.
Importing my RAWs form the EOS 6D (saved on a 95MB/s 32 BG SanDisk Extreme Pro) it renders only the 12 or 24 displayed previews and leaves out the rest (the next only when I'm scrolling down). For 12 images LR5 needs 8-10 seconds. LR4.4 does the same process for all 150 RAWs in 1-2 seconds.
It doesn't matter if I want to import to my workstation (Dell Precision T1650, 8core Intel Xeon E3-1240 V2, 16GB RAM, 64bit) via USB 3.0 (Reader & Port) or to my laptop (Dell Latitude E6400). So it must be LR, not my hardware.
Are there known issues with the Canon-RAW format? I just updated EOS firmware to 1.1.3, but the renderspeed stays the same. For 1 image 3-4 seconds single...
@ Adobe-Experts: Could you please look after this very soon. Importing to different catalogs is not fun...
Thanks,
Ralf

Hi
I'm having a similar problem when importing Nikon NEFs into LR5 (true for two different cameras, D800 and D300). Rendering of previews is a) very slow (compared to LR4.4 installed on the same machine) and b) often incomplete, i.e. not for all files on the card a preview will be rendered (empty frames are displayed). Sometimes, scrolling the preview panel up and down remedies this, but there have been occasions where apart from rendering the first few previews, all the others remained empty no matter what I did. The irritating thing is that I have not found a pattern to this behaviour which would allow to find a root cause or which would allow a workaround.
Computer: i5-760 CPU, 8GB RAM, Win7 premium home edition. LR5 installed on a different physical drive than the catalog and pictures, and the cache file is yet on another drive.
I'm pretty confident that this is due to some issue in LR5 as importing with LR4 (or earlier versions, for that matter) showed none of these issues.

PDF Font Rendering in Preview/Safari on Mountain Lion

Since upgrading to 10.8.2 a few days ago, I have been unable to read any of the PDF statements provided by my bank. To be clear: there was never a problem reading these statements in 10.5, 10.6, or 10.7. The files are not corrupted, nor are the fonts embedded within them. The copies I have saved locally display font characters as boxes of varying colors and sizes rather than actual letters/numbers. The same is true of new copies of the same files I've downloaded from by bank's servers. Observe:
So I extracted the fonts embedded within this PDF, and installed them in the Font folder of my user library. After doing so, the PDF renders in Preview like this:
....which is less than useful.
This PDF, and all the others affected by this issue do render properly in Adobe Reader 10.1.4 -- but that's not the point. I'd much rather use Preview. Has anyone else encountered this issue and solved it?
Thanks.

Indeed, wiping out the caches is not a permanent solution.
I found a couple of threads in some tex newsgroups that discuss this problem. There doesn't seem to be a resolution. There was some discussion that Latex Equation Editor is no longer being developed, but LaTeXIt, a similar program shows a similar font corruption problem. Fonts are fine in Preview until using LaTeXIt (or Latex Equation Editor), when they get 'corrupted'. By that I mean that documents viewed in Preview often come up sans-serif, regardless of the original font, and often special characters, such as arrows above letters (indicating vectors) disappear. Keynote files that use those characters (from, for example, using LaTeXIt under Tiger) show corruption. Rebooting (and possibly simply logging out and back in) 'cures' the problem, ie, Preview and Keynote are once again happy. During all this, Acrobat is always happy.
This is kind of painful, since I give physics lectures using Keynote, and things like integral and summation signs and vectors and such are kind of nice to have around.
Someone has got to know what is going on!

Rendering: Larger Preview.... Stalls in Library Module.

I am running Lightroom 2.4 on a Windows Vista system. I have found recently that when I use the library module and attempt to zoom in on a picture in that module the full size picture on screen reverts to a highly pixalated view (presumably the embeded low res jpeg from the Nikon RAW file) and I get the message "Rendering: Larger Preview..." and nothing at all happens. If I then select the develop module the picture renders correctly, if following this I select the library module again all used to be well but now I get the message "Rendering:Develop..." and again nothing happening.
Has anyone encountered this problem and discovered a solution?

John
Thanks for the input. The problem certainly happens then but I am getting
it other times as well. I found some advice on the forum about the problem
which suggests it is associated with MS Vista's complex file access
permision system. It appears you have to give all users read write and
execute permission on all your Lightroom files. I am trying that to see if
it solves the problem.
Thanks again
Dave

Stuck on "Rendering Standard Previews"

After importing images, Lightroom (2.4) is getting stuck in the "Rendering Standard Previews" process. I have been sitting here for over an hour while Lightroom is stuck at 6 of 117. This happened on an earlier import as well, and I ended up canceling that process -- it was stuck on 1 of 6.
Has anyone else seen this, and is there a fix?
Thanks,
Nick

Actually, I seem to also be stuck on "Preparing File for Editing" as I try to process a photo in Photoshop. Somehow the "process" process is getting stuck.

Lightroom pictures blurred in Library module - Rendering: Larger Preview...?

I am using the latest version of Lightroom running on a system using Vista Ultimate 64bit OS, an Intel Core i7 processor, 12 Gb of ram and two nVidia GTX295 video cards. I problem that I am having is in the Library module, where, when I move from picture to picture, some pictures, at random, will load blurred. The caption, in the lower center of the picture starts with "Loading from Previews" then goes to "Rendering: Larger Preview," and it stays there. I can move to another picture which may or may not load properly. This issue does not seem to affect the Develop module; pictures which load blurred in the library mode are crisp and clear in the Design module.
I did not have this problem running Windows XP!
Any suggestions to address this issue?
p.s. I have read a previous thread which suggested that deleting the preference file might be a solution. I have done this, without success!
jwp

My suggestions would be to backup and check the integrity of your catalog, to render standard previews for all images, and if necessary to delete the previews file and directory.

LR5 import problem with rendering standard previews

When I import from an SD card in LR5, the first phase of the import works fine, then the second phase is to "render standard previews" and the import process stalls at photo #3. If I double click on one of the photos, and then go back to the grid view, the importing continues fine. What is happening and how can this be overcome. Thanks,
[email protected]

I leave it until the bar at the top left of the screen which says 'rendering previews' has finished and disappeared, and I've also taken to using Task Manager to watch and wait until the cpu activity has reduced to zero. As you say, this can take some time.
If I then scroll through the grid of imported images, I find some that still have three dots, and which slowly disappear one by one as they are rendered. That is very tedious, so I go back to select all, wait for the metadata to be collected as shown by the bar, select 'render standard previews' - a new bar appears saying 'scanning existing previews', and when that has finished it puts up the rendering previews and starts rendering the ones that still had three dots on them. It then eventually finishes and the bar closes, but with the last lot, I had to repeat this three times before it scanned existing previews and then stopped instead of starting the 'rendering previews' bar again. Each time it added some more previews, until they had eventually been done, and there were no images in the grid view with three dots (other than the brief flash of dots as I scroll normally).
I've also got in the habit of clicking on 'all photographs' after opening LightRoom and waiting until Task Manager shows it has finished it's 'housekeeping', before starting any work. This seems to minimise 'Out of Memory' dialogs or 'Not Responding' situations.

Hardware Rendering=broken preview (CS3)

Hey guys, im new to the forums, but I've recently encountered some strange behavior. I used to have dual monitors setup but only used one in bridge(didnt use the other for previews) and i was able to use hardware rendering just fine. Then i moved and i left the second monitor off and then images started displaying in a weird section of the preview pane, and part of it is translucent.
I enabled software rendering and it fixed the issue(as per in the support site, it said dual monitors can cause this) but the rendering is a bit slow.
How can i get it back working like it used to with hardware rendering?
Computer is:
Athlon 64 x2 6000+(3.01~ghz)
4gb DDR2 667
512 DDR3 Vram(ATI Radeon HD 3850 chip, with recently updated driver)
1tb WD Barracuda boot/cs3 installed on
640GB WD Green Scratch disk
Thanks in advance
-Josh

This is a hardware issue from the video card or driver. You say you updated the driver and if this this the latest one prehaps the old one you had worked better. Migtht try rolling back to the version where it worked. If this does not work you might have to replace the video card for something faster.

Rendering standard previews

If I import a few thousand nefs (or jpgs or psds), with 'render standard previews checked' on a PC, it does not render ALL the standard previews. If I then run 'select all' and 'render standard previews', it checks for existing standard previews and starts rendering the ones it missed on import. Even then it still misses some, and I have to repeat this about three times before it finally finds it has rendered them all.
Something not quite right?
[Standard previews set to 1640 and high quality, and imports referenced to original location]

I leave it until the bar at the top left of the screen which says 'rendering previews' has finished and disappeared, and I've also taken to using Task Manager to watch and wait until the cpu activity has reduced to zero. As you say, this can take some time.

1:1 Rendering of Previews

I'm confused about rendering 1:1 previews. When would you want to do so? It's my understanding that LR generats them when the are needed, so why generate them in advance? Should I just check the box to use previous previews generate on import?
I've tried to generate them in advance, but they are taking many, many hours to do.
Guidance and insight appreciated.
Thanks!
Reid

Jim,
I had some correspondence with Geoff, although they were posted in the forum. He emailed me:
Reid, I do not use 1:1 previews for my library, only when LR generates them.
I do have standard previews set to 1680 as that is bigger than my screen size, this works fine for me and keeps the disk space taken for the preview file optimised.
It can take some time to generate them depending on your library size but once done it is done, of course I have it generating the standard previews on import now.
I wrote back:
So if my display is 1152x864, then I sould set my preview size to 1680?
What about quality?
What about when to delete 1:1 previews?
What about my existing images already in LR--do I need to delete and re-import images?
His answer:
So if my display is 1152x864, then I sould set my preview size to 1680?
Yes that's about right
What about quality?
I use medium and that appears ok for me.
What about when to delete 1:1 previews?
I have that set to one day, again has not affected anything I do
What about my existing images already in LR--do I need to delete and re-import images?
In library, all photographs,select all, in drop down menu select previews> render standard size previews. That will build them all, then have them generated on import.
That's what my home computer is doing now.

Rendered Standard previews, Hard disk full

Hello,
I'm using Lightroom 4.0 on Mac OS 10.7.3 and used the "Render Standard-Sized Previews" option to generate previews overnight. I had about 30 gigabytes of free space and woke up to find my hard disk full.
Since restarting, discarding the *1:1* previews and purging the ACR cache, I have about 10 gigabytes free, but it seems like ~20GB or so is being consumed with previews.
My "Lightroom 4 catalog Previews.lrdata" package is only 3.53GB.
Is there somewhere I can look for additional rendered preview files to delete them?
Thanks!

You may have a corrupted disk but you do not have a virus. Boot using your original system installation DVD and run Disk Utility. Repair the disk.
If you have no Administrator accounts at all, follow this procedure to create a new, temporary Administrator account from which you can fix your normal one.
Power on or restart your Mac.
At the chime or grey screen, hold ⌘ and S on your keyboard to enter single-user mode.
At the prompt, type
fsck -fy
and press Return.
This is a simple check for file system integrity and is optional. It will take a moment or two to complete. Wait for it to finish before proceeding.
Type the following exactly as written, one line at a time, each line followed by the return key. There is a single space preceding the first "slash" ( / ) character in each line:
mount -uw /
rm /var/db/.AppleSetupDone
shutdown -h now
When you restart the machine, it will take you through the entire setup and registration process all over again. When you do so, create a brand new account with Admin privileges. Give it a simple and disposable name since you will delete it later. Do not choose the option to transfer or migrate information to the Mac.
When it completes, log in under that new account, change your previous account back to Admin, and log out.
Log in using your old account, which will now have its Admin privileges restored. Delete the throwaway account you just created.

AE CS6: rendering RAM-Preview stops when using other app parallel

sometimes rendering the RAM-Preview takes some time.
while waiting I would like at least to read some articles on the internet.
But as soon as I click into an other windows, AE stops rendering.
is there a special setting / workaround to avoid this (user-unfriendly behavior) ?

well, some of the information was given some replies above:
AE 11.0.3.6
Windows 8
Machine: Intel i7-3930, 32GB Ram, 2TB SSD, AMD Radeon HD 7970M
it happens with really any project
yes, I am familiar with speeding up the rendering... still takes alot of time and at least browsing the internet should be possible while AE renders the ram-previews...

Can I delete renders and previews when putting projects into long term storage?

I want to shrink the size of my longe term storage folders. Would it be ok to just delete the previews and renders?
Any project opened in the future is going to rebuild them anyway..
Thanks

I agree with Joe (nothing unusual there), and, as stated, how you do the mechanics might well depend on how you establish your folder structure, when you start the Project. I keep everything (including copies of any Assets), in a folder structure below the Project's name. This article goes into more detail: http://forums.adobe.com/message/4028199#4028199
With such a structure, it is easy to Delete, say Media Cache files, etc., before using Project Manager, or just setting it to NOT copy those files over. It also makes a final Deleting easy.
I do sacrifice a bit of performance, by not spreading, say my Render files, my Audio and my Video, over separate physical drives, but then, when the Project is done, tracking down everything is easy, as I just Delete the root folder, [Project Name], and everything goes with that.
Good luck, and glad that you asked, before archiving a bunch of Projects, or Deleting a bunch of files.

Is rendering a preview unavoidable?

I'm very new to FCP -- starting to make the switch from Adobe Premiere Pro. My Quicktime DV files were captured from camera to disk using Adobe OnLocation. In Premiere, I could import and simply drop them onto the timeline. I could then play the timeline instantaneously -- meaning without any render. The preview would be lower resolution, but very acceptable to work with. When you hit the stop button, the full res sharp image is again seen. With FCP I get the red bar indicating I need to render and when I try play the timeline, I get a blank screen in the canvas, with a message "unrendered". Is there any way to achieve the instantaneous playability as described with Premiere? Am I missing a basic point here -- is there a setting or something else I need to do? Thanks, Tam.

I have no experience with OnLocation, but it's made by Adobe so it's not surprising that it works better with Premier than FCP. What format are the files it creates? (ie .mov/.mpg/.avi) and what codec are they using?
FCP does allow you to see low res previews of your material, but this is generally used for real time effects previewing. If your raw footage needs rendering just to see it you're starting out with a big handicap.
As with all NLEs, you'll have a much happier experience if you convert your files to a supported format and in future capture into FCP (or at least set up OnLocation to create files that fcp likes, if it can).

Rendering Video Previews increases number of videos

Well,
I have a clip that is about 2 minutes long and has 57 video clips, about 10 cross-dissolves and a simple preset look from magic bullet 1.4
When I hit render a few hours ago it said "Rendering 1 of 57 Video Previews" and "Rendering Frame 1 of 2889".....so I took a nap.
Four hours later it's still rendering....and now it sais "Rendering 5786 of 18759 Video Previews" and a similar astronomic Number in Frames.
I found out that it happens when I select the area of my entire clip and hit "Render entire work area" to even render the many yellow parts of the sequence.

I have the same problem as this original post. I have taken a sequence that was incorrectly created using 29.97 instead of 25p and copied and pasted the entire project into a new sequence that is 25p.
I have fixed all the keyframes for the audio which did not come over in the copy and paste and then went to render the timeline. I first tried to render just a short section as a work area so I could see if my rolling credits were smooth. But the render is constantly creating more and more video previews. Far mare than the project has. Estimated time left says 00:00:00 and the render bar never go green past the first 100 frames or so.
I have left it to render for hours just to see if it finishes, but the video preview count just grows and grows.
It does the same whether I render the whole project, or just the work area.
Using Premier CS5 on windows 7 64 bit. Build 5.01
Any help would be greatly appreciated. This first post was over 2 months ago, I wonder if any Adobe folks have an idea of what this problem is?
