Waveform cache, thumbnail cache and autosave vault

Sorry but I still have a couple more questions.
Should i be moving the waveform cache, thumbnail cache and autosave vault over to external hard drive with the media? And where and how are the project files stored on my internal system drive? Just trying to organize the location of everything before I go any farther!

Hey digginin to my Mac. I am where you were a bit ago, and I think I understand your question about where to set those cache files, and I am a little unclear on this as well.
I am probably making a mountain of a mole hill, but I believe you are talking about that bit at the bottom of the window of the Scratch Disc pane of the System settings. I am working my way through Tom Wolsky, and he seems to say to set those three things (waveform cache, thumbnail cache and autosave vault) to go to the external. It's a bit unclear to me though. I currently have them set for my documents folder on my MBP. And in my documents folder is a folder called "Final Cut Express Documents" in which are six folders (Audio Render Files, Autosave Vault, Capture Scratch, Render Files, Thumbnail Cache Files, Waveform Cache Files). I set up a scratch disk, and captured some video to it. It currently has those same six folders. Everything okay so far?
I have just set up another scratch disk, which will actually be my main scratch disk, and will be used for a pretty big project involved many hours of video. I haven't captured any video to that yet. It only has three files (Capture Scratch, Audio Render Files, and Render Files). I guess the other three get created when I capture some video to it. And I guess I can select that particular scratch disk when I go to capture the video.
Am I in the ballpark over here? Thanks in a advance.

Best place to store THUMBNAIL AND WAVEFORM CACHE?

I was taught that when creating a new project, it's best to create a folder
on a seperate media drive, and direct your scratch discs, thumbnail & waveform cache as well as the autosave vault to that drive & folder. This way,
everything associated with that one project resides in that one folder on
your media drive, seperate from the computers hard drive and if you have
to move the project to another computer or delete everything associated
with the project, you just move or delete that one folder.
This has served me well in the past,...but,
I was recently working with (6) different G4 1.2 laptops running FCP 4.5.
It was a training class and the machines were working 8 hours a day for
6 days straight. They were not networked together in anyway.
Periodically, everyone of them would "lose" the waveform cache and thumbnail cache pictures while editing. I don't mean the folders would
disappear, I just mean they'd stop generating the little thumbnails and
waveform pics on the timeline. The temporary fix was to just save the
project, close FCP, and reopen the project. They'd all pop back in and be
there again for a while.
#1 - Anybody know why this would happen?
#2 - It was suggested to me that to avoid this happening in the future,
that you should should direct the thumbnail and waveform cache folders
to live on the HARD DRIVE of the computer, the same one with the app,
and NOT in the same folder as the seperate media drive where you capture
and store your video.
This goes against everything I originally learned, but was wondering what
others might have to say or have experienced on this point.
I'd appreciate any input. Thanks.

gulp ... jumps right in with both feet ...
I think you were taught wrong.
this is not the official path as laid down by the gods of fcp
conventional wisdom suggest that you should set your scratch disk location once and then let fcp organise everything else.
re your questions:
1. no idea ... not the end of the world but certainly a weird glitch tho.
2. some do, some don't ... tiny files w. very low overhead, location shouldn't be a factor in the problem you noted

Thumbnail adresses, and website icons are not being deleted when I clear history and cache, how do I delete these?

I am trying to delete the icons that websites use which are located in the user file of appdata/local/mozilla,
and the website adresses that are located at the bottom of the thumbnails when opening a new tab. clearing data deletes the actual thumbnails, however the adresses are still located below where the thumbnails would be. I have tried clearing history with everything checked, and all history selected to be cleared, and also deleted the cache and cookies. what can I do to delete these things? Thanks

Use these steps to remove saved (form) data from a drop down list:
#Click the (empty) input field on the web page to open the drop down list
#Highlight an entry in the drop down list
#Press the Delete key (on Mac: Shift+Delete) to remove it.

I rebuilt the thumbnail cache and lost all the changes and editing I had made to 4000 photos every photo reverted back to the original

A tech rebuilt my iphoto thumbnail cache and afterwards all the changes and editing of all my 4000 photos was gone!
Every phot had reverted back to the original!!!!! WHAT HAPPENED???? Why were all my changes destroyed? Where are the photos that I edited?
Also a bunch of photos disappeared. HELP!!!!!

Of course there is no reason that rebuilding a thumbnail cache would cause a loss of all editing of my photos!!! But that's what happened.
I was there when the tech rebuilt the library and thumbnails. He held down shift & command and opened Iphoto and a window appeared with "Rebuild Photo Library" with 6 boxes to check such as
1) Repair Iphoto Library Database
2) Rebuild Iphoto Library Database from automatic backup
3) Rebuild the photos' small thumbnails
4) Rebuild all the photos'thumbnails (this may take a while)
5) Recover orphaned photos in the Iphoto Library Folder
6) Examine and repair IPhotoLibrary file permissions
The tech checked all boxes and after Iphoto has rebuilt everything all my editing was gone and all my photos had reverted back to their originals representing 5 years work.
There are no stuck keys on my keyboard of my computer.

Delete preview cache - that should solve the problem.
It's the .lrdata folder in with your catalog, named something like "My Catalog Previews.lrdata".
Delete entire .lrdata folder, making sure you get the one in the same folder as the catalog you're opening. Do not delete anything else, and if you have something like "My Catalog Smart Previews.lrdata" - that's not it.

When Lr comes up, consider initiating whole-catalog building of standard previews (Library -> Previews menu), lest you be "forever" greeted by temporarily gray thumbnails and "loupe loading" indicator in the future..

Problems with non-existent waveform cache...

I previously posted this:
+I cannot open Final Cut. I have an error saying 'The Waveform Cache Files Folder does not have read/write access. Please select a new folder in the System Settings Dialog or correct the problem on disk'. Final Cut then proceeds to shut down, so I cannot change any user settings within the program.+
+I have made all Final Cut folders read/write as well as my external hard drive and anything else with Final Cut on it. It still presents this warning.+
And was replied to with this:
+Delete the Waveform Cache Files folder in the Finder.+
+Open Final Cut Pro by clicking the FCP application icon -not by opening a project.+
+In the Menu bar click on Final Cut Pro > System Settings. Reset the loction of your Waveform Cache Files folder. The folder will be re-created in the directory that you choose.+
So, I have deleted all the waveform cache files.
I copied the Final Cut Pro Documents file onto my hard drive and deleted the original from my laptop. Last night all was running fine.
This morning I have the same warning as earlier:
"The waveform cache file does not have read/write access."
There IS no waveform cache file? I've done searches on both my hard drive and the external hard drive and all that remains are the invisible outlines of the files I deleted last night.
???

P.S. I still have my Final Cut Pro project file (which I am desperately praying is my saving grace) but I can't find other associated files.

Can't Open Final Cut - "Waveform Cache Files Folder does not have read/....

I am new to Final Cut and macs, so please bear with me.
I have created an animation in Final Cut pro (5) using stills. The project takes up a lot of space, which is why I have moved the 'Final Cut Documents' file onto my external hard drive. However, I relocated/reconnected the project files when I next opened the project and all was peachy.
Last night when I had the project open I got errors about not being able to save the project. This was my first problem, but is now insignificant compared to this new problem this morning:
I cannot open Final Cut. I have an error saying 'The Waveform Cache Files Folder does not have read/write access. Please select a new folder in the System Settings Dialog or correct the problem on disk'. Final Cut then proceeds to shut down, so I cannot change any user settings within the program.
I have made all Final Cut folders read/write as well as my external hard drive and anything else with Final Cut on it. It still presents this warning.
A final confession: last night in (I think?) User Preferences I changed some of the settings to my external hard drive (I'm not even sure what settings...I just checked boxes next to the Hard Drive and unchecked a box next to the laptop drive), hoping it would just save the project to it, rather than on my laptop. This may have contributed to this new problem...maybe not.
PLEASE HELP...this animation is due Monday.

Thanks for your reply - it sounds like it will work, but I can't delete one of (yes, I made multiple copies, but have been able to delete the others) the Waveform Cache Folders as it comes up with the error "The operation cannot be completed because one or more required items cannot be found. (Error code -43)." Is this the cause of my problems? How do I fix it?

Waveform cache files

Hi everybody,
What exactly is a waveform cache file and can I open these in final cut pro? The reason I ask this is because I have managed to loose some Quick time audio files which I now need. I have managed to find the old waveform cache files and was wondering if there is any way of using these to save the files? Not really holding up much hope but though it was worth a try.
Thanks
Sara

Hi
The waveform cache files do not contain actual audio but data about the waveform as displayed in the Sequence timeline in FCP.
I'm afraid they will not bring back your audio for you.
Regards,
Jim

Waveform Cache Files. Delete?

What exactly are waveform cache files and can I delete them without worrying about screwing something up?

I guess the only thing you should never delete is your capture scratch? Everything else can be trashed?<<</div>
Even your captures can be trashed .... AFTER you've finished and delivered the final project and the client has accepted it.
I usually only permanently keep project files and any graphics I created for the project. Everything else gets tossed.

How to - move ACR cache and LR cache and catalog

Hi all,
in the try of speeding things up a bit with my LR (v. 2.4 64 bit on Vista 64 SP2, E8650 proc and 8 GB RAM) I got an 2nd hand WD Raptor 150 GB 10K rpm, and I'd like to move there the ACR cache (around 60GB now) and the LR previews and catalogs (around 20 GB) . Which is the right and safer procedure to do that!? :-)
Another question: my setting about File Handling are the following:
1680 pixels as standards preview file size
Preview quality Medium
Never discard 1:1 preview size
and in the grid mode (library) when I page down or up ... I always have the 3 white dots (of waiting) the pictures taken 3-4 secs go from fuzzy to sharp. How can I improve that time?
Thanks to all who will answer :-)
Have a nice day,
gianluca

There is nothing you can do to change the time that thumbnails to refresh. The fuzziness is normal while the three dots are visible and indicates that Lr is scanning the files within the Grid for external metadata or develop changes.
To move the catalog and preview folder you simply drag (copy) it to the new drive, open the relocated folder and double click on the .lrcat (catalog) file. The double click operation will open Lightroom with the relocated catalog active.
You can drag the ACR cache file to the new drive. However, to ensure Lightroom/Camera Raw use the correct ACR cache you will need to open Preferences>File Handling and point to the location that you want the cache files to be saved.
Be aware that moving above folder is going to take a fair amount of time, albeit significantly less than rebuilding the cache and previews from scratch.

Have a problem with Lightroom 5.4. Since the program crashed yesterday it won't launch, it comes up with the message "Lightroom encountered an error when reading its preview cache and needs to quit". " Lightroom will attempt to fix this problem next time it launches". Except that it doesn't, I keep getting the same message and the program closes. Does anyone know what I can do to repair it? Can't back up, can't do anything.

There are dozens of threads in this forum that describe the fix

Statement caching and batch update

Can these 2 JDBC features work together ?
Is it possible while statement is cached to be reparsed (soft) if used in batch update ?
I am asking this questions because i have a sitution where an insert is cached using implicit statement caching and then put in a batch to exeute batch updates !!! From statspack reports i find that 1/3 of statements are reparsed ... even soft !!!

Statement caching and batch update work fine together. The most common cause of unexpected soft parses is changing the type of some parameters. If you first bind one type, setInt(1, ...), do addBatch, then bind another type to the same parameter, setString(1, ...), and do addBatch, you will get a soft reparse. There is nothing the JDBC driver can do about this, the RDBMS requires it.
In general, whatever parse behavior you see with statement caching you would also see without it.

When I publish my site on one specific page where i've added {tag_pagecontent} I get the error:Some files on the server may be missing or incorrect. Clear browser cache and try again. If the problem persists please contact website author.

I'm trying to get a blog module going, I've even deleted the html insert bog with the tag in and re-published which then I don't get the error but as a result no blog either. But then I add the tag in again and publish the error comes back. I've used the dev console and it says that my musicians sample.css is out of date but why is it only out of date when I add in html to my muse site?
HELP!!!! I've searched other threads and to no avail I'm publishing so no direct ftp going on. the only thing I changed in business catalyst was the module stylesheet in order to style the blog. I've tried uploading and replacing all files nothing seems to work. the site is here:
http://www.musicstudentsforhire.co.uk/musicians-samples.html
It's only this page as it has the blog on. Also I've noticed when I've re-published occasionally it will show the mobile version on my desktop and not the desktop version??? no idea why that's happening so I've had to turn that off. any explanation on why that is happening would also be much appreciated.

I haven't received an answer as of yet, I'll post t on here when I do. I de-activated the mobile site because it's my clients site so he needs it to be operational during the day. I hope someone gives me an answer soon.

How do I get Firefox to show the proper font and layout of a site when it keeps loading an older version of that site? (I have cleared cache and cookies already)

We are having a new website developed and my designer has made changes to it. Despite clearing the cache and cookies, the fonts are not showing up as the actual fonts. Also, the form fields at the bottom are extending beyond the border on the right side of the box on my screen, but this does not happen for other people using Firefox - it is only on my computer.
I AM ON A MAC.
I received a suggestion to reload the page and bypass the cache with:
* Press "Cmd + Shift + R" (MAC)
BUT - this did not work.

You can reload the page and bypass the cache with:
* Press and hold Shift and left-click the Reload button.
* Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
* Press "Cmd + Shift + R" (MAC)
