Imported images have stretched smart previews

I see these stretched smart previews after importing some photos, about 3000 photo's.
And they arent rotated. After waiting for about 10 seconds the previews onm my screen change to normal.
I first imported them with build smart previews off and also on.
How can I force LR to update them or someting like that?
Thanks,
Ludo

I get about 1 G SP per K of photos. In other words, 1000 Photos (which consumes about 10GB on disk) have 1GB of smart previews. Most are raw but some jpeg. So here's one data point: ~10%.
So from my limited experience 16% seems high, but 5% may be an exageration by people trying to "sell" the smart preview enhancement - dunno.
Number of raw vs. jpeg files will be a significant factor, but I haven't done the math so...
One thing to try is experiment: make one-photo catalogs with different images, so you can see exactly how many bytes are the smart preview corresponding to each photo - maybe you'll find a pattern...
Also worth noting what type of raws you have. Such will be a factor, but again: I haven't done the math..

RAW FILES NOT LARGE AFTER OUTSOURCING LR SMART PREVIEWS : images staying at Smart Preview sizes. What is wrong?

My friend's RAW files won't go back to the large size they were after outsourcing LR SMART PREVIEWS to outsource editor.
what went wrong? When she sent the files to the outsourcer they were NOT zipped together.
They were ZIPPED back to her however.

Describe exactly what steps were taken. It doesn't make sense that the editor sent her smart previews. Normally she would do Export to Catalog, checking the box to include smart previews, and send this exported catalogue and its smart previews to the editor. The editor would then send the catalogue back to her (the smart previews are no longer needed), and she would do File > Import from Another Catalog.

My 3.4.5 has ~ 35000 jpg masters. I have set aperture not to create previews on import and have ensured "maintain previews" is not ticked. Every time I start aperture it insists on creating previews for ~ 4300 images. Why?

Having had the previews created I selected all photos and "delete previews". It did this quickly and no more previews being created. Once aperture is closed and then re-opened aperture immediately sets about creating the previews for the same photos. I don't understand why this should be happening.
This is occuring on my Mackbook Air (Aug 2012) which has 256 GB storage. I am fast running out of space as I am using "Managed Masters". I intend to make the masters referenced by relocating them to an external HDD but before doing this would like to clear up this problem first. I keep my Vault on the external HDD and have Time Machine and Time Capsule. When I have relocated the masters to the external HDD I intend that TM backs the external HDD to the TC. I tink that I will use the second partition on the external HDD for Carbon Copy Cloner to back up the Mackbook Air.
Any help or advice warmly welcomed.

Frank
Many thanks for your input.
Following your advice I have selected all the projects individually and checked the status of Mantain Previews. Some were indeed marked up for Mantail Preview so I have unmarked them.
I have also selected Photos and deleted previews and also repeated this for My Projects.
Checking the Get Info for the Preview folder in Aperture Library in Finder this now tells me that I have zero bytes for 564 items.
Close and then reopen Aperture and it regenerates these564 previews in the blink of an eye. I haven't been able to locate these photos yet. I know there are about 120 in facebook and 10 in photostream but dont know where the rest are.
It seems the issue is not with Aperture but with myself and not understanding Aperture sufficiently well
Do you see the problem this way?

Imported images have poor colors

Friends,
I'm a new user to Motion 5 having what I hope is an easily-solved problem. I want to create an animated image sequence. The images were originally created and stored in Aperture. Because I understand that Motion does not permit import from Aperture, I exported the images to a folder as full-size .jpgs. I then imported them into Motion.
Unfortunately, they did not import well. They are of a lower resolution and the colors are off. What am i doing wrong?
If it matters, I'm using the late-2009 imac with mountain lion.
Thanks!
Steve

JPG is a *lossy* compression format. You probably exported the images with compression. Many applications start JPG compression at about 70% and if you weren't paying attention to that detail, the images may suffer loss of quality (actually the DO suffer loss of quality, it's just not always that perceptible... until "later").
Image formats that are lossless:
PNG
TIFF
PSD
possibly a few others, but my favorite one is PNG with PSDs a close second (so I don't care.)
Also, if by "lower resolution" you mean smaller in size, there's a Preference to regulate how Motion imports large images. On the Project pane of preferences, at the bottom: Large Stills > select Do Nothing. Motion will import the images at full "resolution" (that's an overloaded term— in programming parlance). You'll have to manually scale or fit them into your "scenes".

Imported images have jagged edges when scaled down

Perhaps I'm missing something really obvious (like the quality thing in the After Effects timeline), but I imported a Photoshop image, a logo, scaled it down to 15%, and it has jagged edges. Ditto for a TIFF version of same. Starting resolution is plenty large.

You can adjust the apparent size of the image in the "media" tab of the property inspector. Select the photo in the media bin (not the layer in the timeline), then the media tab in the insepctor.
try reducing the size of the image to the size you are scaling it to (of course, you'll have to adjust the scale property of objects in the timeline which use that image). for example, if the image is 1000px wide, and you're scaling it 15%, then adjust the media size to 150px and restore the scale to 100%.
YMMV but it's worked well for me. sometimes adding a slight gaussian blur helps (<.25). it would be more effective to scale in an image editing app (like photoshop) to the desired size, but this is more flexible.

Imported images have edges?

I am importing a giff image that I masked in Photoshop and no
matter what I do it has a white edge on it once it comes over.
What's the deal? Anyone know a fix?

Try saving it out as a PNG file. Make sure the image has
transparency in photoshop before importing to Flash.

LR5 Smart Preview Portability Question : Can files be edited remotely?

I understand how Smart Previews work. What I'm unsure of is...will we be able to edit these files remotely, separate from the host computer? For example, I'm an image editor and I live 500 miles away from the photographer that I work for. Can they (the photographer) download the images after shooting, create Smart Previews then send me the 'Smart Preview' folder of images, I edited them on my own computer then return the Smart Previews back to them fully edited?

You don't actually edit smart preview files. Meaning: you edit the photos in the catalog, it's just if they have a smart preview they don't need to be online. In other words, the smart previews are tied to the catalog, and exist in it's bowels - edits are never stored in them, and you can't detach them from the catalog and do things with them, like send them to somebody. If you edit an offline photo by way of it's smart preview, the edits are stored in the catalog and/or the xmp of the photo, just like if you'd edited the actual photo.
So what your photographer would have to do is send you a catalog which includes smart previews, and you would return an edited catalog to them (without the smart previews), to import .
eh?

Can I use my lrdata smart previews file on another Mac and then take the edits back to the original?

LR5 CC user. I have tried to use Smart Previews for the first time. I followed what seemed the best advice but now not sure since most of the guides feature working with a single computer and offline files. I am away travelling for over a month. I have a Mac Pro with many thousands of images. I exported my 5000 "best" as smart previews in a lrdata file to use with my macbook pro laptop while travelling. i took the lrdata file with me on a hard drive. Not the catalog file. Now it seems I can import these files (by double clicking on the lrdata file) but I am concerned that if I edit them the editing will be lost when I go back to the original. They have different file names. Have I basically lost the chance to do any editing? Or is there a way to edit and then send them back to the original catalog?

One should not import & edit smart preview files (the lossy dngs with names like 7/7FB5/7FB580F4-00BB-4C39-8DE5-C09490BA6CB8.dng), instead of the photos they "represent".
But if you do, here's how to transfer settings and/or metadata from imported/edited smart preview files back to the original photos which you should've edited in the first place:
o Note: you have to import the directly-edited smart previews into your main catalog when you get home (import from travel catalog, or save xmp first and just import files - either way works).
* Download and install RelativeAntics plugin (free by me).
* Choose 'Imported Smart Previews' preset (in plugin manager).
* Select the imported smart preview files.
* Run 'Relative Antics' (File menu -> Plugin Extras).
* Deselect all items in 'Define "Related" section, *except* 'Custom Relative'.
* choose whether to transfer develop setting and/or metadata..
* and do it - this will copy settings and metadata from the selected imported/edited-smart-preview to the photo which should have been edited in the first place (the "related" photo).

LR 5 not creating smart previews

I set create smart previews when I imported my images...none show up.
I selected some files (with originals available) and went Library>previews>create smart previews...the tast bar zipped across the top left but no previews were created.
Any idea what setting may be wrong that make this happen (or not happen)
Thanks
Tom

Rob-
There is no smart preview icon next to the original photo icon on the top of the right side panel.
I do have a smart previews . Irdata - looks more like a file than a folder? It also shows that it was last updated almost a month ago - I should also say that I keep my lrcat and lrdata files in a folder on dropbox - could this have anything to do with it.
When I've created the smart previews, I do it as I import (using LR to import).
I do my imports from cards on whichever computer (desk or laptop) expecting that since it's going to the LR files on DropBox it doesn't matter - they will be available to both computers (if I am importing to the laptop, I later move the files to the external HD with finder and then have LR find the files once they are in the final resting place).
To test this. I imported a few folders on the desktop, unplugged the external drive where the originals are and LR did not show the smart preview icon.
This actually doesn't matter on the desktop, but I was hoping to delete all original files on the laptop (which I'd better not do yet :-)
Thanks for your help.
Tom

Is having the smart previews file, lrdata, mandatory?

I mean, I don't foresee, in near future, to use detachable hard drives, or photo servers or anything. So my photos will remain in my main laptop. So, do I really need to have and retain an .lrdata file which will hog my disk space?
Also, after a preview is discarded, will it be generated again, if I open the file in Lightroom later?
Thanks,

I would not delete any .lrdata files, as dj said LR will recreate them and I would expect LR to do so.
As for "Smart Previews.lrdata" hogging space, it will only hog space if the OP uses smart previews, I don't use smart previews (at least yet) and don't have a "Smart Previews.lrdata" file, I only have "Catalog Previews.lrdata" file which I would never delete.
I am assuming that if the OP has a "Smart Previews.lrdata" file, the OP must be using Smart Previews, perhaps because of LR Mobile.
Just for reference, widely quoted in this forum - Preference and other file locations in Lightroom 5

All tracks have the same preview image after import

Hi,
when importing some videos (h.264) into iMovie'08, all have the same preview image. I would expect them to hava an image from the clip.
How to fix this?
Arne

The files are on disk in my pictures folder. I took them with my Sony camera as mpeg2 and converted them with MPEG Streamclip to mpeg4 (h.264).
Just updated to iMovie 7.1, but did not change anything.
The icons are all of the 1st clip. Moving the mouse over them always show the 1st clip and the audio of the first clip in the thumbnail, but in the preview I see the correct clip.

Importing both smart previews and standard previews crashes

I understood that Lightroom does not use smart previews as previews in most cases and still uses previews as before for working on. I normally import as standard previews because this improves speed whilst working on them. I have just ticked the smart preview box for a couple of files that I thought I might want to work on after transferring them to my externsl drive and it crashed when set with standard, OK with minimal, I am now wondering if in fact the smart previews are the previews it works on and that by setting it to standard as well it has confused the program and that is why it crashed, but then why have the option of both or is it simply a computer resources issue trying to create both standard and smart previews.

Regular previews are primarily for library module (e.g. you need them for loupe view).
Smart previews are only for develop module and exporting (they provide image data in lieu of original (e.g. raw) file).
There is no "conflict of interest".
That said, I have no idea why it crashed unless maybe you ran out of disk space or something (?)
If (because of some problem you are having) you want both but you have to pick one, pick smart previews. Regular previews can be created from smart previews, but not vice versa (yes: it will take time).

When trying to import images from an external hard drive into Lightroom 5 it states no preview for the files selected

Go easy on me here….
Trying to import images from external hard drive into Lightroom 5 but the selected images state 'no preview for file'.
All other images on the external hard drive can be previewed and imported without issue.
I have tried adding the images onto the computers hard drive as well but still no joy.
I've used Lightroom 5 previously and had no issue so convinced its the files I'm trying to import (jpeg files).
Any help greatly appreciated.

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp? So far when I try to disconnect the external HD from the mbp, I get the following pop up window: The disk "external hard drive A" couldn't be ejected because "Lightroom" is using it. Quit that application and try to eject this disk again. When I do that and restart Lightroom 5, the Adobe Photoshop Lightroom - Select Catalog screen pops up but doesn't list my external hard drive A as a choice.
I've reviewed Adobe's Lightroom Help | Smart Previews Lightroom 5 web page and still haven't been able to figure what I'm doing wrong. Any help would be appreciated.

Your internal HDD. by default, is named 'Macintosh HD'. From what information you supplied, it looks like there is already a Lightroom catalog installed on you local (internal) HDD using the standard naming convention Adobe uses as well as a Lightroom catalog on your external drive which you created. To be sure of which catalog Lightroom is loading when it starts up, To do this, start Lightroom as you normally would. After it starts, select the Lightroom menu item, then select the Catalog Preferences item and finally, navigate to the General tab. The Location information will tell you exactly what catalog Lightroom is opening by default. This will likely be the Photography Mac Book Pro Versions catalog on your external HDD. Once that is confirmed, you are ready to proceed. As an additional test/verification, you can shut down Lightroom and, this time, start Lightroom while holding down the ALT/OPTION key. This will cause Lightroom to pause and display a screen which will allow you to chose a different catalog to open. Navigate to the /Users/[user name]/Pictures/Lightroom folder and select the Lightroom 5 Catalog.lrcat file. When Lightroom comes up, there should be no previews or folders as this catalog should be empty. Now you can be certain which catalog is being used and which catalog has all your data and you are ready to migrate your current catalog. Shut down Lightroom.
To migrate your current catalog, use Finder to locate your Photography Mac Book Pro Versions folder on your external drive. Select the folder and select COPY from the context menu. Next, use Finder to navigate to the /Users/[user name]/Pictures/Lightroom folder on you internal HDD. You can start at the Macintosh HD level and work your way down by opening each level (Macintosh HD/Users/[user name]/Pictures). Select the /Pictures folder and then select PASTE... from the context menu. When the COPY/PASTE is complete, you should see the following files on the Macintosh HD:
Macintosh HD/Users/[user name]/Pictures/Lightroom/ and
Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions
The Macintosh HD/Users/[user name]/Pictures/Lightroom folder will contain the empty default catalog the Adobe created when Lightroom was installed and Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions will contain a copy of the catalog you created on your external HDD.
You are almost done now. Make sure your external drive is still attached for this step. Restart Lightroom using the ALT/OPTION key again. When the Select Catalog screen appears, select the Choose a Different Catalog button (lower left side). When you do, a Finder window will open to allow you to navigate to a catalog of your choosing. Navigate to Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions and select the file Photography Mac Book Pro Version.lrcat. This is the copy you just created. Select the Open button and Lightroom should start. You should see all of your previews and settings just as before. Also, in the left hand panel, all of your folder should show up and none of them should be dimmed and none of your previews should display a small exclamation point badge. Either a dimmed folder name or an exclamation point badge indicates that Lightroom can't find the associated image file. If everything looks good, go to the Lightroom menu, select Preferences and then select the General tab. Under Default Catalog, select an option to either load the LAST catalog opened or select the Users/[user name]/Pictures/Photography Mac Book Pro Versions catalog from the drop down. Shut down Lightroom and then restart it normally. This time, when Lightroom starts, you should be viewing the new copy of your catalog. You can confirm this by looking at the General tab on the Catalog Preferences screen (Lightroom/Catalog Preferences menu items). Shut down Lightroom once again and this time, eject your external drive before restarting. This time, your folders in the left hand panel will be dimmed but you should be able to work with your smart previews. If Lightroom should display a Select Catalog screen with the external drive detached, double check your settings as it indicates Lightroom is still looking at the copy of the catalog on the external drive rather than the new copy you made.
Finally, if you are seeing dimmed folders and/or exclamation point badges with the external drive attached, this indicates a problem. You can select any folder and select Update Folder Location from the context menu. This will allow you to navigate to the copy on the external drive and select it. Lightroom will then update the catalog (select to synchronize the content). This will not only clear the dimmed folder problem but also remove the exclamation point badges for all photos in that missing folder. However, it may indicate that not all went well with the copy of the catalog so make sure to verify all went well. You can use the Get Info option on the two folders. You should see the same number of files/folders for both the copy on the internal drive as well as on the external drive but you can't rely on the byte count because of the possibility of differences between the geometry of the two drives. Hope this all helps!

I have been using LR5 on a Mac mini. The LR was installed on an external drive. Now I would like to use Smart Previews on my Internal drive to take advantage of the speed. When I make previews they go to originals. How can I put them on the internal drive

when started with LR 5 on my Mac I used advise from Adobe's LR5 book, I installed it on an external drive, processing originals was a little slow so I decided to make smart previews on my internal drive to get faster processing. However the smart previews hook up with the originals and so there is no advantage just a bigger file. Is there anyway when I make the previews stay on the internal drive or am I locked in with the current setup. I can find no LR5 folders on the internal drive.
Thanks,
John Sr.

Are you doing a lot of spot removal or brushing?
This doesn't sound like a disk drive issue at all. Once Lightroom reads the file from the disk, and you are editing, the disk plays no further role. Using a faster disk drive here will not make the slightest difference.
So, I would check your graphics drivers to see if they are up to date. I would also temporarily disable your virus checker and firewall.
How much memory does your computer have? What CPU do you have?
How big (in megapixels, not megabytes) are the photos you are editing?
