Yes, I did and I got a strange outcome.
I checked Quicktime, and I reinstalled it.
I restarted the PC.
When LR4 opens, the processes
- Adobe QT32 Server.exe.
are not working.
After I opened the import dialog these services started.
For the first time after restarting the PC; I could import a small video and I could playback it without problems.
The second try of importing more videos (4 small ones), went well, but at the playback moment, everything freezed again.
I tried to restart lightroom and to kill the processes listed above, but I had no luck.
Only restarting the PC I could (and not always) importing the videos. The playback did work just few times.
If the first task, after restarting the PC and Lightroom is importing (without waiting the previews of the importing box) generally there is no problem.
If I work with my catalog, which contains videos as well, then the importing dialog (for videos) is not working.
The playback feature seems to be a matter of luck, 90% ot times is not working well.
I run a Windows 7 64 bit machine.
A similar problem was reported as a bug in this post, and if so I wonder why there are not many other users reporting the same problems.
I really hope I can solve it, without waiting for a bug fix.
The major problem with working with video files is that they are not all created equally, especially AVI files. The video features are largely in Lightroom to work with files that come directly from DSLR cameras. It can support more than just those files, but there are also issues with codecs.
Marco, did you convert your LR3 catalog to LR4 so that the AVI files you had imported previously would automatically be in LR4?
Do you still have LR3 on the computer? Can you verify whether you can import the AVI files that will not import into LR4 into LR3?
Yes, I did convert my "old" LR3 catalog inton LR4. All the old RAW, Jpeg, and avi files are now visible in LR4 catalog. Anyway, still I cannot playback avi files.
I tried to import the same new avi file in LR3 and I had no problem, actually I never had problems in LR3.6. But, when I import directly into LR4, no way: a lot of problems.
I still have LR3 installed...
I'm afraid is really a problem of codecs, although I can playback my video files with Quicktime without problems.
Anyway it is strange that the video files from DSRL are supported and the video files from one of the most common 4/3 camera (usually used also by prosumers) is not supported.
Hopefully, there is a solution. If not, I am afraid I have to manage my video collection with another program, waiting for a LR4 upgrade. but it would be a very unpleasent situation.
Thank you for trying to understand what's going on, I'm looking forward for your advice.
there's a KB article here http://helpx.adobe.com/lightroom/kb/video-support-lightroom-4-3.html
and make sure in your firewall that Lightroom can establish connections to 127.0.0.1 (your own computer), that's obviously how it connects to the media server that it uses for video files
How can I be sure the the firewall is allowing lightroom to establish connection to 127.0.0.1.?
I'm using norton internet security 2012.
I set lightroom 4 and other services (dynamiclinkmediaserver.exe, dynamiclinkmediaserver.exe) to "always allow" incoming and outcoming connections
