Quicklook no longer working with AVi files in 10.7

Howdy,
Mysteries abound! Updated to 10.7, and ever since, I have been having two problems:
1. AVI files no longer open open using QuickLook; all I get is is the AVI icon, and the "Open in VLC" button.
2. The icon preview for AVI files is no longer displayed as well; only the generic VLC icon shows (and yes, I have the "Show icon preview" box cheeked in the Finder preferences).
Is anyone else having the same problem? Does anyone know how to remedy this? Thanks in advance! (^_^)

Flip4Mac (installed) and Perian (installed) provide this support. As a matter of fact, I can play AVI and WMV in Quicktime 10.2 and 7.6.6. It's the Finder or the QuickLook subsystem what has a problem.
Besides that, having those QuickTime components installed, there are no problems in a new installation from scratch in a nother disk. But I'm trying to avoid that and to restore in Mountain Lion part of the functionality of my Mac under Snow Leopard.
There should be a preference, cache, temp file or something like that that is impeding QuickTime or the Finder to access the necessary components to preview and quicklook AVI and WMV files.

Quick Look no longer works with AVI files.

Hi
For some reason, quicklook no longer looks inside avi files. I get a black screen and audio, but no visual. This is a recent problem, nothing has changed on my system other than itunes 9 being installed. AVI files worked fine with quicklook but have now stopped.
Anyone have any ideas what could cause the problem? I've rolled back to itunes 8 but the problem persisted.
thanks

Hi there
I had this problem too but I think that I have a good solution for ya!!! Ok do you have "Perian"?
If so then go here; http://www.perian.org/#support and at the line that say's "removing obsolete QuickTime Components" just do this and voila it should all come back to normal.
Hope this will help ya, let me know!!!

Quicklook doesn't work with .avi files

Hello, i've got a little problem right here on my mac. The thing is that I used to have Snow Leopard as a OS and quicklook used to work great, it opened all the extensions I used to work with. The thing change when I format my HDD and installed a clean copy of Lion OS. Now quicklook works fine as it used to but not any more with .avi files. I remember that this feature was working great on my previous OS, and it's really important for me to find a solution because quicklook is an absolutely amazing feature of our Macs.
I've tryed to download plugins, restoring permissions or even trying it with a guest user, but no success.
Please help me. If you need more info about specs or something i'll be glad to give them to you.
Thank you!!!

Also doesn't work with Grapher (.gcx) documents (an Apple format).

What is the best way to work with avi-files?

Hallo all,
I'm new to this forum so before asking my question I'd like to say some words about myself:
I'm not a native english speaker, so please excuse language mistakes I'll possibly make and feel free to ask if I'll write something which you don't understand due to this fact.
Half year ago I bought a HD Cam from Canon (Legria HF 200) which - in my opinion - has a good quality (good enough for my hobby films), and realized that cutting HD films on Windows would require a lot of expensive high end hardware. So I bought a MacBook and Final Cut Express - a decision I'm very happy with.
After the first disastrous tries to make a small clip I bought Tom Wolsky's "Editorial Workshop for FCE" and now I'm more happy than I was before (because I've seen that you're posting here: thanks for the great book!)
But now to my question:
I have 9 old PAL DV tapes (containing family clips which I'd like to cut now) recorded with my old JVC, which has a FireWire port only. Unfortunately my MacBook doesn't have such, so I have to capture to DV avi using a PC with Pinnacle Studio.
1.) The avi files are very large (between 13 - 18 GB). Because I'm not able to recapture due to the missing FireWire port I'd like to archive the material on an HDD. How should I convert the AVI to make it smaller without a great loss of quality but keeping the ability to use it in FCE (especially when reconnecting after creating the subclips from the original)
2.) I'd like to keep the whole captured tape content as master clip and work with subclips from it. Yesterday I converted such an AVI to Film using QuickTime (the size didn't change noticable) and used the DV-Start/Stop detection. Unfortunately that didn't work correctly - some of the markers have been set in the middle of the shots instead as expected exactly between them. Should I do this on the original AVI file to make it work? And if, is it possible to reconnect the subclips created this way to a MOV created from the original AVI?
3.) On the PC I get an xml file containing the correct position data of the subclips (as timecode, if I remember correctly). Is it possibly, to use this data in FCE to mark subclips? Maybe by putting it manually into an xml project file or something similar?
4.) Or is there any other way to solve my problem?
Sorry for the big post and thanks in advance,
André

You're welcome, and thank you for the reply.
2) Yesterday I made the subclips with the In-Out Points and Command-U, the benefit is that I've seen the clip before naming it. Now I'm using markers, it's benefit is that I can write comment and (the later) clip name at once, the drawback is that I have to view to the next shot's beginning before knowing what the shot contains.
But now I found out that I can reconnect my clips independently to the format I converted the master clip to. I reconnected the media to the original AVI file and it worked, too! The more I work with, the more I'm sold on it... - although it doesn't seem to be able to read and use the date information within the DV AVI.
1) Ok, I tried something similar within FCE. Just worked, but the file size still remains. Which codec settings should I use? Is the export to DV in MOV with a quality of 75% acceptable for both file size and quality? Or would be encoding as H.264 with best quality an option for archiving, knowing that I have to convert it back to DV if I (maybe) wan't to use it for editing later? Or anything else?
Thank's in advance again,
André

Working with AVI files

Is it possible? My camera renders AVI files. I can import the files fine, but they just show a blank white screen as they play. Is there anything I can do or do I need to get a different camera or software? I'd appreciate any help. Thanks.

Hello Carskill,
your AVI files need to be converted before it's possible to edit them in iMovie. AVI is a so-called container - within that file there can be any one of many codecs used to compress video (the same goes for Quicktime .mov files).
Try opening the file Quicktime and looking at the Movie Info window (cmd + I). It should show what codec was used incompressing the video and according to that you'll need to choose the software for conversion.
One tool that recognizes many AVI files is FFmpegX

For more info on AVI files have a look at Dan Slagles Unofficial iMovie FAQ: Working with DivX and AVI files

hope this helps

Help Please! working with avi files.

I need to import an avi file (320 x 240) into FCP 3. The clip will be composited with a title that was originally in eps format which I have converted into a PSD file.
When I put them on my sequence it both need rendering. I have adjusted my sequence settings to match the files but still rendering is necessary.
The avi properties are:
320x240
30 fps
6.8 MB / S
Alpha : none/ignore
Composite: normal
pixel aspect: square
Compressor field is blank
Sequence Settings are:
320x240 Multimedia (large)
30 fps
Data Rate field is blank
Alpha field is blank
Composite: normal
pixel aspect: square
Compressor: DV/DVC Pro - NT
The PSD file also needs rendering to view. This is when they are just individually side by side on the timeline, not even stacked above one another. How can I get both the avi file and PSD file to play without rendering?
My deadline for this intro clip is tomorrow and I need help quickly!

I was going to wait till you bumped your post again.
Don't do that.
Please.
There are dozens of AVI codecs that have been obsolete for ten years and even more that never made it to the Macintosh. QT may or may not be able to open them. If you can play them, export from QTP to conventional DV and bring the newly created copy of the movie into a conventional DV sequence in FCP. There are other AVI conversion utilities.

Quicklook no longer works with iTunes 8.0.1

When you open the Movie or TV folder in Finder, the file icons begin changing from iTunes icons to a blank grey icons and the files can no longer be viewed from Preview or Quicklook.
Is this an intended design change or is it a software oversight with iTunes 8.0.1? In either case it's very annoying, as I use Quicklook extensively.

It was a precursor to my G4 HD going south. Had to rebuild from scratch and it's fine.

Cannot download updates, and I can no longer work with RAW files without them. Help!

I used to be able to get Bridge to read RAW files, but I cannot any longer. I think I need an updated plug-in, but when I try to go to help-updates and download them, the message I get for all three (Adobe Bridge CS5 4.0.5 update, Photoshop 12.0.4 update for Photoshop CS5, and Photoshop Camera Raw 6.7 Update) is this: "There was an error downloading this update. Please quit and try again later." I have tried shutting down and restarting the computer a few times over the course of several days, and have even tried updating my mac software. I always get the same message. Please help! Thank you!!

Ok, Adobe. I'm having a huge problem with your customer service here. You list no email or phone to contact you, yet I have spent hundreds of dollars on a product I can't use unless I can get an answer to this question, which appears to be a problem with your system. I've used the forum, which is the only option you list for contacting you, and have heard no response. Can anyone please help me?

Adobe Update Ran, Now PP CS4 No Longer Works with MPEG Files & More....

I think I know what this is but I thought I would make sure.
(Running CS4 Master Suite in Windows 7 Home Premium with 16GB Ram, i970 processor and six short stroked drives for cache, files, etc.)
Last night Adobe Updater popped up and wanted to do some installs. I had already been editing a project usine PrPro and AE for several hours so called it a night and initiated updater. This morning PrPro no longer recognizes my MPEG source files! Niether does AE or ME. In PrPro it hangs on "conforming." Did I get hit with the Revert to Trial bug? Could it be something else?
What I have done: cleared all cache files, rebooted, checked cache settings, rebooted, wiped deleted cache files, rebooted, cursed.

Welcome to the forum.
Sounds like the Revert to Trial Bug. See this ARTICLE for details and the fix.
Good luck,

Working with .avi files in FCP

Hello guys,
I have a challenge.
Friend of mine has .avi footage, codec is DV PAL 720x576 at 25 fps.
I need to edit it in FCP 6 and create video for YouTube.
What would be the best way of doing this?
Should I leave it in DV PAL 720x576 at 25, edit the footage in this codec and frame rate and export it as it is?
Or should I set Timeline settings to DV NTSC 720x480 at 29.97 and export it as that?
Or any other codec, like H.264?
What would be the best way?
I don't want the video to be stretched into HD on YouTube or anything like that. Just simple, most effective way without loosing much quality.
Thank you so much for any tips.

Hi Michael, thanks for your note.
I actually do not need to have 24 fps, I just thought that it will make a better performance on YouTube.
But if it doesn't make any difference, then I gues 25 fps is fine.
So in that case, all I need to do is to export my DV PAL sequence with current settings and then convert it in Comperssor to H.264/
So I will end up with H.264, 720x576, progressive, 25 fps ? Is that correct?
Thanks again Michael for your support.

No longer audio on .avi files when attempting to use Elements 9

I have compiled 20 years of videos from family videos and converted them to .avi files. I now want to edit these files into other smaller videos to give to my children. I have Premiere Elements 9. When I get one of these files using PE9 there is no longer audio on them.
There is audio if I play them on Windows Media Player but no audio on Quicktime Player.
I can edit in Windows Movie Maker but not in PE9.
The Quicktime Player states the following:
Format: Motion JPEG Open DML, 640 x 480, millions
Movie FPS 29.97
Playing FPS 29.97
Data Size 1.94 gb
Data Rate 8.67 mbits/sec
Normal Size 640 x 480 pixels
Current Size 640 x 480 pixels
I have a Dell Inspiron 530, 4.0 gb RAM, 32- Bit Windows Vista system. Plenty of Hard Drive availability.
I purchased PE9 because I thought it would be superior to Windows Movie Maker. Very frustrated.

Hi Bill,
The .avi file is a compilation of videos from multiple cameras from over the years. There is no 1 camera. That is why I am confused here.

What camera produced the MJPEG files, wrapped in the AVI container? The reason that I ask this, is because camera mfgrs. love to tweak CODEC's, and some take that tweaking to an extreme. If you have the utility disc, that came with the camera, it is probably best to install their particular version of the MJPEG CODEC. The Morgan, or the MainConcept might work OK, but having the exact version, from the camera mfgr. will get you as close, as is possible, and will save having to buy an MJPEG CODEC, that might not be perfect. Now, on that utility disc, one might have one of three possible choices: The MJPEG CODEC might be a separate installationThe MJPEG CODEC might install along with the camera's driverThe MJPEG CODEC might install with an included editing/cataloguing program (most common nowadays), and even if you do not use that utility, having the proper version of the MJPEG CODEC installed on the system, will get you as close, as is possible Good luck, and let us know if you have the utility disc for that camera.

Has anyone not working with .dv files had synchronization problems?

Has anyone not working with .dv files had sound synchronization problems? I'm not exactly sure what the alternatives to DV are, but I think one of them is HD.
The reason for asking this question is to help isolate the nature and cause of a very serious flaw in iMovie '11. In the original release of iMovie '11 (version 9.0) there was a small--but serious--synchronization problem. In the 9.01 there is a large synchronization problem. We know of one person who has not experienced the problem, and he is not working with DV files (media). So we want to find out if anyone who is using something other than .dv files is experiencing a lack of synchronization between sound and picture. Knowing the answer to this will help with figuring out where the cause lies. For the initial iMovie '11 release (9.0), you probably would not notice a problem unless you had very long event-clips, e.g., two hours long. Events get this long if you are transferring from analog 8 mm tapes. Even then, it would have to be in scenes in which the connection between event and sound is obvious, e.g., close ups of people talking. It isn't until the 9.01 release that most people would notice anything. All we need to do is establish one case of a synchronization problem in which the person is using something other than DV.

Hopefully, the 9.0.2 release will make my question moot. Zyfert must have posted the announcement of the release just as I was formulating my question. Still, if you have information on the subject, it would be interesting to hear.

My ipad2 is no longer working with my Keydex speakers..no volume

My ipad2 is no longer working with my Keydex speakers..no volume. I'm playing music from my free Pandora.

In addition to jmarton's comment. You need to go through the process of setting up the Console One mount directory where all your GroupWise MTA and POA files have been mounted for access by NCO. Unlike NCO on Windows, NCO on Linux has no idea about UNC paths. So you need to create the exepected set of mount points for NCO so it can access them. Without these, it will be as if you have no domains.... But if you have NO groupwise menu options, including Create New GW System, etc. That does point at the plugins as being the issue.
You can look in the About-->Plugins IIRC to see if they are showing up. You can start NCO with debugging to see if it struggles, and where. I believe the NCO startup options would be --debug --windowout [ --showhiddenobjects ] or some combination thereof.

Spotlight on NFS no longer working with Mavericks, works with Lion

We have a muliprotocol NetApp filer with NFS and CIFS. Has been working great with Lion and Windows clients. We now have 2 OSX 10.9 users and although they can connnect and transfer files, the spotlight no longer works on this filer. I have done all the start stop mdutil commands, says it is indexing for a few hours but never gets any results. Spotlight still works on the local drives.
Any ideas?
