P: Can't Import video in LR 4.1

I followed the suggestion to remove DIVX software. After rebooting there was some improvement: now both dynamiclinkmanager.exe and dynamiclinkmediaserver.exe shut down correctly after closing LR4. Also, video clips from my Panasonic TZ7 already in the LR3 catalog play correctly in library mode.

However, the following still does not work:
- I am not able to import new video clips. Thumbnails display "preview not available", importing results in an error message that there is a problem with the video file.
- all video clips already in my LR3 catalog and shot with Nikon D90 do not play. Thumbnails still have a triangle with "!"

update: LR 4.1 RC2 has shown improvement in video editing now. I can view videos - some not that smoothly -but I CAN scrub and trim clips from my 7D DSLR. There's seems to be some caching in playback - it does stutter. LR is not my main video editor - I use Sony Vegas 11.

I purchased an upgrade from LR3 to LR4 but have a serious problem. I have many short video clips in my catalog in the same folder as my pictures. I shoot video and pictures with a Nikon D90 and Panasonic TZ7.
As soon as I open a folder (in library mode) which contains video files some background programs are started like dynamiclinkmanager.exe and dynamiclinkmediaserver.exe. After a few seconds the latter one uses a constant 25% of CPU while in LR all video files in the upper right corner of the thumbnail get marked with a ! in a triangle. Both process remain active (including 25% CPU load for dynamiclinkmediaserver.exe) when LR4 is closed, they can only be killed via windows taskmanager. I have also tried to import new videofiles but I am running in the same problem here: I have not been able to import any video files, I tried several different formats!!!! This was never a problem in LR3.

I have seen reports from other people that seem to have the same problem. For me LR4 is completely useless because of the fact that many folders in my catalog contain videofiles resulting in the problem described above as soon as I open one of them. I'm seriously considering a refund if this problem cannot be solved!!

Some additional info:
- PC with Icore5, 8GB RAM
- Windows 7 64-bit
- Video's open and play correctly in Quicktime (V7.7.1 build 1680.42)

Please let me know what I can do to get rid of this serious problem.

Thanks for the comment. I am not an expert in video formats. So, the question is: is there a feasible path (obviously involving some kind of conversion from mpeg2) to display those video in LR or it is not possible without heavy quality loss?

Beware that MPEG is a lossy format. If you re-encode you will loose in quality.

This sounds exactly like my second issue. Though not all of the videos are affected. The funniest thing is that there is no setting difference between those that get played and those that don't for a same given camera.

I have to add to the movie issues in LR 4.1RC.
MOV videos from Canon 7D - while they are imported - do NOT play or scrub and can't be trimmed or edited. The video place holder is there - but videos don't play.

However, the performance of still photo develop module HAS improved in the 4.1RC.

Becky thanks for your answer. I appreciate your openness, even if it is disappointing for my needs. Just to be sure, I am looking at the following page: http://helpx.adobe.com/lightroom/kb/v... which states that file extensions MPEG and MPEG4 are supported: but nothing is said about video formats.

I am researching the possibility to convert my mpeg2 files, to which format should I (try to) convert them: mpeg1 or mpeg4? Or do you suggest another path? Or do you recommend against trying this conversion?

Thanks in advance for your feedback.

Francesco, I hesitate to say there will never be a solution - "never" is a long time. But I don't see MPEG2 support for Lightroom 4.1.

Bec

thanks for the explainations
That is a real shame, a huge part of my collection is MPEG2
that makes lightroom unfit for these.
I hope you can quickly come up with a solution
