This has been on ongoing problem with PrP since I started using it in CS5 on both the Mac & PC platforms.. Its a shame it hasnt been fixed yet. Its a large source of frustration and embarrassment.
I created a dynamically linked clip in PrP and after finishing the AE comp I saved in both AE then PrP it last night. I come in this morning and the render is gone. I go to the preview files folder and there they are.
I feel confindent this is a software issue. My system has been optizmized by ADK for performance with CS6. This is intermitent but occurs with some regularity.
Ive made many bug reports in the past with no response so unless I am personally contacted Im not going to waste my time. As a beta tester I got a sense of how issues are dealt with so I have no unrealstic expectations about this one since its been around for a while.
Personally I haven't heard anything about losing Dynamic Links on CS5.
As far as I know, people started losing them on CS5.5, and in 99% issues were related to incremental naming, whereas just about 1% - related to Media Cache errors, general system failure etc...
If you're currently facing the latter, just try cleaning up Media Cache Database.
My expereince of the incremental naming issues was that the images displayed by various DL clips were wrong. Images from DL Clip 1 were being displayed by DL Clip 2. Stuff like that.
This issue is different. Premiere is unable to find the Preview file that was created last night and is still in the same place.
I will give the data cache cleaning a shot, but I dont think it will resolve this particular problem. We shall see.
I haven't yet seen a definitive cause for this, and hence no definitive solution. It seems to just happen sometimes for some folks, but not for the majority. That can make tracking down the issue quite difficult.
Although your ongoing issue may not relate to incremental naming, the latter also causes losing rendered previews.
After cleaning up the Media Cache Database via Preferences within either AE or PrPro do not hesitate to delete remains in both Media Cache and Media Cache Files folders manually.
Cleaned all the caches and saved the project. 2 hours later opened the project and 1 out of 4 rendered DL AE preview files were not found by PrP. I found it right in the folder where it should be. Each time this happened over the last few days it lost a different file.
Things like this will really hamper CS 6 acceptance into the professional community. Losing renders is real bush league.
I gave up on the dynamic link thing pretty quick. Cool concept but definitely not ready for prime time. I just do the old render and import. Then, if I have to change something in AE, I overwrite the previously rendered file with the new one. That way it is immediately updated in PP.
When I try to reproduce and then fix an issue with ADL, which is not related to incremental naming, I normally clean up all MPEG and XMP files in a project Preview Files folder as well. Time spent on rerendering preview is usually much less than the one spent on reconforming after clearing up Media Cache Database.
And I'm not sure I follow your first sentence: when I clean up Media Cache, I normally do it when a project has already been saved. And after that I close PrPro, delete the remains manually, restart PrPro and let it reconform all media files once again. After that I rerender a preview.
If I remember correctly in some severe cases users had to deactivate and then reactivate PrPro along with clearing up Media Cache.
P.S. Actually any bug can make a user feel frustrated. Some people get irritated by CS6 spanned AVCHD clips issue, some other ones - by PrPro reaction on pressing Stop button within Multicam Monitor. World is not perfect...
Yes, Evil , I have also done that work flow in the past. In fact, if you export from AE with "Project Linl" checked. you can select the rendered AE movie on the PrP timeline and use "Edit Original" to reopen the project.
I was just hopefull that AE CS6.03 had finally addressed this embarassing and time wasteful behavior. Apparently not.
Yup, also did that process. Deleted all the previewe files as well as all the cace files. Didnt resolve the issue.
Gee. thanks for the lesson on the nature of perfection in the universe. I'll let you know when Im interested in hearing more of your observations on life
I see this behavior as well, sometimes just switching back and forth between the two pieces of software it will lose track of render files. It sucks to open a project a couple hours later and the dynamic link renders are gone, they are so incredibly slow to render as it is, I don't want to lose them.
I'm still on 5.5 and was expecting huge performance gains with dynamic linking when going to CS6, but from what I'm seeing here on the board I'm guessing that's not the case.
I realize I can just export out of AE (faster then PrP} then use Edit Original to reopen the AE project on the PrP timeline, I was just hopefull this inconsistant bug a boo had finally been fixed.
However, if you keep losing Dynamic Links after clearing up and rebuilding Media Cache Database, including clearing up Preview Files folder, and is still keen on resolving the issue, provide some more details on your PrPro project and linked AE one(s):
- what type of media files are used in the problem project?
- what is the order of building dynamic links for that project?
- what are the names of dynamically linked project(s) and comps?
- does the behaviour depend on which effects are used in dynamically linked comps?
Meanwhile, although I didn't lose any Dynamic Link so far on my own projects and was able to reproduce and fix almost any voiced on the Forum issues with ADL, I can't be of 100% help since I'm still on CS5.5.
Hey Fuzzyy. the Universe just called. It said not to assume to speak for it
Like I said its imtermittent and unpredictable. It doesnt happen all the time, just enough to slow things down.
Media is all AE motion graphics. No media from cameras.
I build links from the timeline to AE and also start in AE and drag into PrP. So the answer is I build both ways.
Names are unique ones I assign.
There seems to be no rhyme or reason that relates to anything like effects / media / etc.
I do appreciate your thoughts
Well, with such sort of input data it's hardly possible to reproduce and accordingly fix your particular issue.
By the way, if you're communicating with the Universe by phone, it was a hoax I'm afraid, since we are on Skype for several years now.
No I saw it. The first part is not relevant. There has yet to appear in these forums a definitive cause for this phenomenon. People will sometimes lose renders, without relation to platform, media, Dynamic Link, etc.
I would appreciate if you could point me out to those threads on the Forum, in which ADL issues were described in the same way as happening out of the blue with no pattern at all. I probably miss them.
