Rendering 1:1 previews is slow!

While LR5 was whiling away a day (or two or three) rendering 1:1 previews for 70,000 nefs etc, I had a look at what it was doing using Windows Resource monitor.
Having read that the reason for .dat files is to speed up rendering, I was surprised to see that LR5 was reading the .dat files, the original .nef files, the .xmp files and the catalog and previews.db while rendering the 1:1 previews (standard previews had already been rendered after upgrading). So my question is why does it have to read them all? The .dat files are supposed to be the part-processed image files, and the .xmp files only contain what is already in the catalog. So to my simple mind, LR5 should only need to read the .dat file and the catalog, and the catalog is open already.
Interesting to note that rendering smart previews didn't read the .dat files at all. I'm beginning to think .dat files are a waste of time and space.
Bob Frost

My understanding is that the dat files are created either during a 1:1 preview render, or a load of the file into Develop. So is it possible that they were being written during your 1:1 preview render, or perhaps being checked to ensure fully up-to-date?
As far as their usefulness is concerned, yeah that's a moot point. My current understanding is that they won't be used if a Smart Preview exists, i.e. it's the Smart Preview that is read during pre-load of the image into Develop. So if you have Smart Previews created, you don't need the ACR cache entry....

Updated to LR 5.4, images now importing extremely slow. After importing and rendering images are still very slow to go through and develop. No issues in LR 5.3 which was very fast.

After importing and rendering images are still very slow to go through and develop. No issues in LR 5.3 which was very fast. Canon,Nikon, Leica and Fuji files all rendering slow. iMac 2.9 ghz 16gb RAM OSX 10.8.5. Catalogs and images are kept on external drives. Drives running fine. Really need a fix on this since I'm norally imported and processing at least 4,000 images per LR Catalog. Is there way to revert back to 5.3? I can't use 5.4 is its current state. Thanks.

Download LR 5.3 and install it
By the way, lots of people have this complaint about LR 5.4, and the advice I give is to use LR 5.3 unless you need one of the new camera models supported by LR 5.4

My Preview is Slow :(

Since the new update (Im not sure) of Adobe Muse ..... the Muse preview has slowed down ... even the browse (chrome) preview takes a very long time to load. Its definitly not my computer because i have a really powerfull machine. Can some one helpo me ???

Hey ! Zak !
Thanks for the reply !
- Im currently running Adobe Muse 7.3 and the update was from 7.2 to 7.3.
- Im using a Mac. All my machines are the top of the line models.
- When i perview my site using Adobe Muse i get something like this (http://192.168.2.10:33333/Preview/mysite/index.html)
- Here is the businesscatalyst website.......ive just started working on it......so yea : http://onefoot01.businesscatalyst.com
Since previewing within Muse was taking too long.... i started to publish my site and preview it as a website from businesscatalyst.com which was really really fast !
For example...say...If you use the built in "Muse Preview" option the site or page takes a very long time to load fully.... i even tried putting only a blank canvas with a simple colourfill, this itself took a long time.
Is there a way to fix this issue ????

FCP 6.0.1 Running and previewing extremly slow

Ever since I upgraded to 6.0.1 FCP is running extremly slow.
In my current project, I brought in a HDV QT.mov that needed to be Chroma Keyed and color adjusted. Previewing the chroma keyed file looks horrible (all jagged) unless I render it. That takes time. Then I added a piece of stock DV footage under that, blurred the background and it played back like crap until I rendered it. More time. And so on.
I can't make any adjustment and see how it looks without rendering.
When I was working in 5.1 FCP I was able to add all type of files and zip right through them pretty much. Now I can't seem to get my settings right or something...so as I apply different effects or filters I can never see on the fly how it looks without rendering it first. Then of course...if it's not right...I tweak it again but can't see how that looks until I render it again.
All my video files resides on a RAID that I created from 2 of my internal drives and it also is my scratch & render disk.
It's eating my lunch on production time.
Any suggestions Please.

You could try setting the render in the sequences you work with to ProRes. Found in that sequence setting's video processing tab.
But the real fix is to not work in HDV at all. If you have an Intel mac, a capture card like the Kona LHe card will transcode your HDV directly to ProRes... or AJA's Io HD (at the high end of this workflow) will transcode the HDV to ProRes on board the box itself... The Io will take your HDMI signal directly from the camera and transcode it to anything. It starts shipping any day now.
You're a brave soul attempting chroma keys with HDV... they are nigh on impossible to look good. But ProRes will make the rendering times go way down, and give you more real time playback of effects.

Multiprocessing works for RAM preview, extremely slow and aeselflink crashes when in Render Queue

Hello all,
System specs:
Hackintosh
OSX 10.9
3.5Ghz (overclocked to 4.2Ghz) Core i7
Geforce GTX 580 classified 3GB Cuda GPU
AMD Radeon HD 6870 1GB Display GPU
32 GB of RAM
System SSD
5 drive internal RAID
After Effects CC 12.2.1.5
Cuda drivers up to date
I'm having a problem with the render queue and multiprocessing. I have a moderate sequence with several effects and 3D layers. When I'm working in the composition, everything goes great. I can RAM preview and all my CPU cores will kick up to 100% and render the composition in no time all; with full resolution with no skipped frames. It works fantastically.
Then when I go to render the exact same composition with the same multiprocessing settings, AE will hang at the "initializing background processes" for at least 5-10 minutes, during which the CPU will ramp up to 100% but no frames will be rendered. AE still remains responsive, as I can hit the stop or pause buttons and the queue will be cancled. But then the aeselflink processes (up to 8 of them depending on my settings, I've tried several) will still continue at 100% cpu load even with AE not set to render anything. I will have to go into the activity monitor and force quit each process. If I leave it for 5-10 minutes, it will finally stop initalizing and start the render, but the CPU will still run at 100% but the frames will crawl slowly forward at about 1 frame per minute, with an estimated 28 hours to render frames that were rendering in under a minute during RAM preview.
I have tried both reducing the number of cores AE will use, adjusting the allocated RAM, and disabling multiprocessing alltogether. When I disable multiprocessing, the render slows to a complete crawl, and it will render around 1 frame every 5-10 seconds. Again, this is on a composition that rendered in less than a minute on full resolution with RAM preview.
The only way to get this composition to render is to export it to Media Encoder, which will render it (without multicore processing, unfortunately) in about 8 minutes, still not the blazing fast RAM preview but at least it finishes it in under 3.5 hours (the amount of time that the multiprocessing disabled render in AE will take).
Here's the multiprocessing settings that have been very stable and carried me through other projects. Disk Cache is not enabled. The only other thing that is disabled is the "Disable Layer Cache" under the Secret menu as the plugins I'm using (Plexus 2 in this case) doesn't like to update when the camera moves so this option has been disabled to force it to reset each frame.
Does anyone know what is going on?
Also, please don't tell me that I should not use multiprocessing or instruct me on basic steps as to increase preformance on my machine. I have been tweaking my memory and multiprocessing settings for a long time now, and it is completely stable in everything but this setup. So please no answers saying "just don't use multiprocessing". It was made for a reason, it's effective, and it's needed. And please don't say that it's the hackintosh, either, as it's the most stable and powerful computer I've ever used. Sorry for the disclaimers, I just want to have constructive help.
Thank you in advance for your ideas!

Hi Rick, not sure if you saw the part where I said please don't reply with turning off Multiprocessing, and I did not say that it works and is effective in all areas. However, if you actally take the time to read my post, you will definately notice that RAM preview with multiprocessing takes under a minute to render a scene. Multiprocessing disabled and rendered in AE takes 3.5 hours. In Media Encoder it takes around 8 minutes. Clearly it IS working and IS effective for my case and my rig. Any vendettas against MP does not help my situation at all.

CS5 RAM preview is slow if I do other things while it's building

Good morning!
I'm experiencing a strange issue. 1080/29.97 comp on an 8-core w/ 16GB. Multi-proc rendering is off.
If I RAM preview the comp (800 frames or so) and wait while AE builds the RAM preview, it plays back fine & at speed.
If I start the RAM preview, then go work in Photoshop while it's building, then return to AE and attempt to play it down, I have the green bar like a normal RAM preview, but it plays very slowly -- almost as if it's re-rendering every frame (actually slower than if I just hit spacebar to render&play on the fly).. maybe 1fps. If I stop and play those frames that it's slogged through, they then play normally.
Is it possible that RAM previewing while I'm using another app (e.g., Photoshop) is resulting in the frames being written to swap disk or elsewhere so that they're being re-read into RAM when I actually try to play it? Disk caching is disabled in the AE Prefs, but...?
Thanks in advance for any ideas -- very annoying.

Photoshop) is resulting in the frames being written to swap disk or

Yes. That is possible.
Be sure that you're reserving enough RAM for other applications.

LR 1.1 Rendering 1:1 previews takes FOREVER...because of DNG settings?

Computer setup:
Mac G5 dual 2.3ghz, 4gb RAM, 220gb free space on system disk, LR catalog/images on Western Digital 1TB external via firewire 800. LR renders standard previews (1680 medium) on import and also converts to DNG with full size previews. LR writes to XMP.
Problem:
Since updating to 1.1, like many others, I have experienced slowness in the program. I got my old library converted to a catalog just fine and have optimized it. It seems when I press Z to zoom in to a 1:1 preview in the Library or Develop module, the image stays pixelated with the "working..." or "loading..." notifications up, even after 10-15 minutes.
There have been times when I add a rating to an image, that the text confirming "Set rating to 5" stays up for 7-10 seconds before slowly fading. LR was very responsive when I was using 1.0, but things have stopped working since the update. I'm wondering if it is because I have the DNG conversion set to render a full size JPG, an option that was not available in 1.0. I would like to avoid having to re-import all of my images, partially because there's just over 15,000 files and also because I'm scared of losing my collections, virtual copies, and flags. I have tried to optimize the catalog, but it didn't do anything. Anything else I can try?
Thanks.

My Lightroom performance has been brutal since version 1.1. The simple task of setting a photo rating to "1" takes about 10 seconds (during which time the Lightroom black title bar goes white and nothing else is happening).
I've searched through this forum and the Adobe Knowledge base and can't find a solution.
My computer (P4 3GHz 2GB RAM) was more than fast enough with Version 1.0
The other awful time waster is when say doing an Export and needing to choose a folder for the files to go. As soon as I click on Choose, it takes at least 20 seconds for Lightroom to display the folders in the 'browse' list. And Lightroom has this delay EVERY TIME Choose is selected!
Lightroom has some great features, but for my professional work, at the moment it is more of a time wasters than of benefit.

Building smart previews much slower in Lightroom 6 than in Lightroom 5

Building smart previews is much slower in Lightroom 6 than in Lightroom 5.
Creating a smart preview from a DNG (Fuji X-E1 raw file) takes about 12 seconds.
Enabling/disabling GPU accelaration does not really make a difference.
When monitoring the Lightroom process with Process Explorer the GPU usage is always 0.
Below is my system specification.
Anyone got some idea why this might be?

Mac Pro has problems rendering and RAM previewing in Adobe AE

I've been using Adobe After Effects 7 and I have a 3g new Mac Pro. It's a great computer, really fast with Final Cut Studio Universal, etc. and when rendering sequences in FCP the program doesn't quit. BUT, when I'm trying to RAM preview or render a composition in Adobe After Effects the application will quit unexpectedly everytime. I found that it would only quit when the composition was over approx. 30seconds, but I've used an eMac that never had problems rendering much longer clips. The fact that the program quits after a certain amount of time makes me think it is an issue with RAM availability to the program, as in a conflict with the program, and the new intel-based Mac Pro. I've asked around on the Adobe website but there is no specific solution. Has anyone heard talk that the intel-based Macs or new OSX, are conflicting with Adobe applications, etc?

Mostly correct, Jim. Photoshop CS3 (UB) Beta is available for download and a time-limited license to CS2 license-holders. The time-limit is unspecified, but Adobe says it will end when CS3 is released.
All good reports the last time I checked on various fora.
(CS3 install does not overwrite CS2, so in case Adobe releases CS3 and pulls the plug on those time-limited CS3 Beta licenses, you'll still have CS2 to limp along with until you receive 3.)
CS2 seems to work fine on an Intel Mac, though slower because it's running in Rosetta. Heck, I'm using CS without difficulty, other than the slowness.
However, all that doesn't help the OP with AE, which isn't scheduled for a UB release until mid-2007, IIRC.

Powerful System With Bottleneck: PPro CS6 Preview Very Slow.

Hello there!
I'm a YouTube MotoVlogger filming with 3 GoPro cameras in 1080p, which I stack up in Premiere CS6 to get different angles. I also sometimes make use of a green-screen for other fun things and will export this as an uncompressed TGA-sequence from After Effects, with alpha of course.
I've been having really bad problems trying to preview my project in Premiere CS6, and despite my system being fairly-powerful, I know there's a major bottleneck somewhere—probably with my HD setup with respect to editing. I basically can't preview a TGA sequence (which is repeated 3 times at different scales) without rendering first.
Initially, I suspected my video card since it was a GTX550Ti and wasn't fully-supported, but only has 192 CUDA cores. I went and got a GTX 680 with 1536 CUDA cores but noticed no real improvement. I am also not getting any kind of yellow pre-render indicator in Premiere. It's just all red and doesn't preview well at all.
My system specs:
Dual XEON Hexacore, 24-cores total
48GB RAM DDR3
SSD Boot drive (OS)
Main Drive: Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive (Premiere installed here).
3TB Backup drive (USB 3)
NVIDIA GTX 680 Video
Of course, had I known about this RAID stuff or that I would get heavy into editing, I would have gotten the system built with RAID 0, but I don't have it and I have a lot of stuff installed, from 3D Graphics to Audio software, vinyl cutting, etc.
So, am I correct in my guess that my HD I/O is way too slow? I need to try setting the scratch disk to the SSD, but there's only 24GB available. Total storage is about 128GB or something like that.
I was thinking of going with a USB3 External Raid 0 setup. Would this be a good fix for my Project files?
Any help is appreciated.
On an unrelated note, is it just me or is anyone else having issues using FireFox with this forum? My cursor keeps jumping back to a prior line of text! Super annoying.
Thanks!

I have read other messages that indicate that PPro does not LIKE to be installed to anything other than the boot drive... and it sometimes (often?) does not work properly if installed to anything other than the boot drive
Since you have PPro installed to the same drive that you are using for video files, you are overloading your data transfer capability... in effect, you are using only one drive (see below)
Trying to use only ONE Hard Drive for Video Editing
You are a music conductor, with a baton that you use to point to various parts of the

Now, at the same time and with the same hand... while still using the baton to conduct

You as a person cannot do both at the same time with the same hand

Placing an image in Indesign CS5- Previews are slow

I have a customer with identical intel MacPros, 10.5.8 OSX, 8GB RAM and running CS5.
Whenever they go to PLACE an image in either InDesign or Illustrator the preview window that comes up takes up to 65 seconds for a preview to appear in the window. These are images(TIFFs or EPS) that are over 200MB.
What I've done so far:
Timed image preview when placing an image from server or off of desktop- No speed difference in showing the preview.
Took my MacBook Pro and tried to place the images- Immediate preview, no matter the size of the image. Desktop and over the network.
Started their MacPros up in target disk mode- Launched InDesign from their computer- No problem.
Started my MacBook Pro in target disk mode- Launched InDesign from my computer- Same speed issues with preview appearing when placing an image.
Replaced their current video cards with accelerated high end graphic cards. - No performance increase. When previewing a placed image, still very slow.
None of my other customers have this issue. Any clues????

There have been sporadic reports that changing the preference for live screen drawing to delayed from immediate has helped other issues such as this.
Try that first and let us know if it corrects the problem.

Editing pdf files in Preview painfully SLOW with mavericks! Why? How to fix?

Editing pdf files in Preview is painfully SLOW with Mavericks! With mountain lion everything was so smooth .... Why? How can I fix this?

I stopped using preview. Adobe Acrobat Pro is running fine ... this is not a solution to the problem though. The question remains open: why is preview not running as before?
Why did I upgrade?!

Preview very slow with .nef photos

My preview works well for .jpg but not .nef.
Open folder, select 'all' right click, open with 'preview'. Very slow & jerky.
Used to work fine with .nef in Mt. Lion.
Any ideas?

Same issue here, and 10.10.2 brings no solution… Haven't you heard yet, Apple is the new Microsoft?!
Anyway, here a few tips to speed up Preview at least a bit, so one can use it for work again:
tip1:
Delete /Library/Preferences/com.apple.windowserver.plist
Delete ~/Library/Preferences/ByHost/com.apple.windowserver*.plist
Shutdown OSX
Startup, immediately press and hold the P and R keys while holding down the option (⌥) and command (⌘) keys before the gray boot screen appears, which resets the PRAM
tip2:
Turn off "Smooth Text and Line Art" in the Preferences. Of course, that's really sad, because PDFs then look terrible, but at least they are easier to work with.
tip3:
For just viewing, use QuickLook: in the Finder, select the PDF and hit [SPACE]. Strangely, QuickLook isn't affected by the bug.
Anyway, those workarounds helped me a bit (thanks to those who posted them), but of course it's no proper solution. The last option would be to go back to Mavericks.
I heard the problem was reported to Apple when Yosemite was in beta, summer 2014. Nothing happened so far. Apple really has to get its act together…

Fast Previewing is slow, how to fix?

Can anyone help please! While I'm editing it takes a lot of time for stuff to render, for example in this video After Effects Tutorial - Basic Typography & Motion Graphics - YouTube he moves everything around so smoothly and you can see that he's moving it. For me I can't see the process of moving things I just see the 'square' around the text and when I realse the mouse it shows me what type of change I've made. I tried messing around with fast-preview options, using anything I could find to fix it, but haven't found the solution yet. I'm using the "Classic 3D' renderer just like he's. PLEASE HELP!
NOTE: I was doing a typography animation and everything was just fine, but in the middle of it (idk maybe i pressed something wrong, i'm still kind of a noob) something went wrong and it all started lagging, making my work really hard,

Did all of what you said and still no results. It's still the same and it's quite annoying, because when I want to start a new project I can't move anything freely and see that I'm moving it. It really makes my work a lot harder if not impossible. I want to be able to move things smoothly like the guy from the video. And like I mentioned I was able to do it, but then in the middle of project everything just got ruined.

RAM PREVIEW VERY SLOW (FAR FROM REAL TIME) ON NEW MAC PRO

Good afternoon
I have the new mac pro with 8 cores, 64 Gb of Ram and dual AMD 700 graphic card, but the preview on After effects is slower than in the old mac pro (from 2010). I have set the preferences as told in your website and everything stills the same. Could you please advice? is very frustrating to see that a new machine works worse than the older one.
thanks
