Question

Aperture reprocesses previews for all videos every time I open it

Hello,

I use Aperture to organise all my videos shot on Canon 7d and an old HD Cam (705 vids, 381GB). Whereas my stills are stored in the aperture library, the videos are imported into eparate folders named after each project inside one master video folder.

I do this because it is an easy way to work with all of them in FCP (X), importing them without moving them, keywords from the folders coming across (and also because FCP used to incorrectly display the meta data- date and time imported shown as the file's creation details, when accessed via the aperture library menu from FCP, this bug has probably since been corrected)..

After restoring from a time machine back up recently, Aperture now reprocesses previews for all 705 movies every single time I open it, reboot or not. It doesn't hang on any particular file or crash but (as it's a mid 2010 MBP) simply slows Aperture down below useable for a few mins until they are done.

Post import processing set to camera previews, new projects always create previews ticked.

What am I doing wrong please? Should I attempt to fix the database?

Best

Ben

As a work-around - hold down the shift-key, when launching Aperture. That will defer the generation of Previews, so you can start working immediately.

What is your Aperture version and MacOS X version?

After restoring from a time machine back up recently, Aperture now reprocesses previews for all 705 movies every single time I open it, reboot or not.

Was Aperture the only thing you restored from a Time Machine backup? Or did you restore more of your system? If you reinstalled or upgraded the system, there may be now video codecs missing. In that case check, if reinstalling additional video codec (Perian, Flip-4-Mac, or similar) may help.

If the reinstalled aperrture library has been created on a different mac, there may be permission problems after restoring from Time Machine. Check the permissions and ownership on your video folders.

Are you touching the videos in any way, when using them in Final cut? Using stabilize or something? If the " last modiied " date is changed by Final Cut, this might prompt Aperture to recreate the preview.

Thanks so much for the work around Leonie.

To answer your Qs.

3.5.1 and 10.9.1

A whole system restore.

The majority are Canon h.264 codec, surely installed.

Permissions seem fine (I have read and write)

The original library was created on this mac and I haven't opened FCP or modified the files.

I have used the repair permissions and fix databse options in aperture. Haven't rebuilt the library.

Thanks again

Ben

Yes, that codec should be installed.

Check the list of supported formats - have you changed the pixel sizes?

It is best to stick with standard sizes.

Do your videos play well in QuickTime?

I noticed a funny behaviour with my videos since updating to mavericks. Quicktime will first show a panel with the message "converting", before opening any movie and never save the changes.

If in Brower view, with only thumbnails displayed, you highlight one video, and then click to choose Viewer mode, what happens?

In the video 'smart album' a small number of random movs (different each time) look corrupted after I let the 700 vids reprocess. The files then won't play in aperture, fine though thru quick time fcp etc.

Now noticing that aperture will not 'see' certain iphone 4s videos from off the HD in the import menu, only from the iphone itself and even then when imported I get 'video format not supported'. (Again file plays fine in quick time and quick preview from finder).

iphone vids should work in aperture surely especially when coming off a phone? so possible permissions and or corrputions? Thinking of starting again with everything permission clean, ie not a restore of previous library but keeping the same files and folders. Any suggestions about how to do this best, I still want to keep photos in the library and vids in folder outside. Any point redownloading aperture itself? Software was restored from back up last time

Many thanks B

Where is this video folder residing? If on another drive, how is that disk drive formatted?
