        I tried severasl variations of source and destination codecs and couldn't get this to work on either Mac or Windows.   Wish I could

          This is so dissapointing. The whole "switching to CPU only rendering but Keeping Preview files" thing worked for me in 6.0.0 but now it doesn't.  And what if there are QT files in there? I didn't see anyone actually explain what happens if there are QT files. Also, why the heck doesn't "Use Previews" just work? It doesn't work at all for me and this is totally unacceptable. Back to FCP 7. Good grief...

            6.0.3 was a Windows only update and only to solve a security certificate issue. No other features were added or bugs fixed.

             

            If you have the problem that preview files are not being used, please file a bug report: http://www.adobe.com/go/wish

              I was reported it 2 month ago, still no luck, no answer, no bugfix.

                Again, excepting the QuickTime issue, there is nothing you have ever needed to do to "make it work" other than check the box.  If it ever hasn't worked for you, then something is probably wrong with your installation.

                 

                This is 100% false. Several people in this one thread alone have confirmed along with me about the "Switch to CPU render mode, keep previews" workaround.

                 

                Additonally, every single poster in this thread should be posting their Sequence Settings, Project Settings and Output Settings.

                 

                But of course it takes a random user to request such a logical step forward toward constructively isolating the issue and not a Moderator who just instantly denies the existence of a bug based on zero evidence.

                  I can confirm that this same issue occurs on Premiere 6.0.2 on the Mac. Using your method seems to have fixed it. So thanks for that! I'm reporting the issue to Adobe. But it seems that others have already done the same. Hope they can fix it. I can see myself accidentally hitting "delete preview files" when doing this. And that would sssssuuuuck.

                    Great. Glad it helped. And yes, I have accidentally deleted my previews a few times this way. And yes, it sucked really, really badly.

                     

                    Still awaiting some help and/or a mature admittance to how moderators keep writing off real bugs as user error when so many users are corroborating and reproducing the same issue and all ending up here from searching the internet for a solution to their very real issue. I guess it could just be magic. Magic is always a possibility...

                      I also confirm the workaround only in workstations with a cuda card, in the case of ati cards the problem still persists. I also noticed that the "export with previews" seems to work if you export previews generated from premiere built in effetcs. If you use colorista or any other non adobe effect the bug appears. It would be great if adobe take note of every discover that users made about bugs to help fix them soon

                        That must be why it's never worked for me - we use colorista a lot.

                          Sorry for my english. I continued with the test and I was wrong!!!, premiere pro built in effects doesn't work either, I put 4 effects and export faster but does recompress again, Please adobe fix it!!! If this were an old bug, I would understand the delay, but just cs6 have this bug, before all was ok. I like premiere pro but seeing how fast Final cut X have significant updates (10.0.6) gets me upset.

                                So after completing 100's of projects using Premiere CS6 and the method that I explained in one of my previous posts to quickly export/encode timelines using preview files I ran into a problem. Whenever I use the Shadow/Highlight filter on a video clip and render it, Premiere can no longer find the preview file for that clip when I export or encode a timeline thus making Premiere rerender all the effects in that clip and the entire timeline.

                                 

                                I didn't do an upgrade to Premiere so I'm not sure why it now does this. I went back to my last completed and rendered project and timeline I finished a couple days ago and 90% of the 100+ video clips had the Shadow/Highlight filter used and it will export and encode the timeline using the preview files without issue. I haven't tried to rerender anything in that project to see if it would still work though.

                                  Well, after rebooting 3 times during troubleshooting I finally decided to turn the PC off/on and that fixed the problem.

                                      So, I came across a new thing with the Use Preview Files" workaround when exporting. When trying to export using the Preview files on this last project it was hanging up and rerendering the effects in the timeline so it was not finding the Preview files as it usually does with the "Software only" workaround. This was a film transfer with 20 reels of film in the timeline all with various color correction filters on them. Some reels were cut into sections so that I could apply different types of color correction and reframe the image when needed. What I decided to do was to see if it was the entire timeline causing it not to find the Preview files or possibly a specific reel in the timeline. I first tried exporting just Reels 6-20 and to my surprise it found all the Preview files and exported quickly like it should. I then tried exporting just Reel #1 and this is when it initially looked like it found the Preview files and then slowed down like it didn't. I had Reel #1 cut into 2 sections with the 2nd section slightly reframed so I decided to take the 2nd section out and get it back to just one continuous section. Rerendered the timeline for that reel and it found that new Preview file for the entire reel and exporting quick. So I went back and tried all 20 reels, the entire timeline, and it had no problem finding all the Preview files now and exported it quickly without having to rerender the effects.

                                        Just tested to see if Premiere CC fixed the "Use Preview Files" bug in CS6 but no go, still the same problem and solution. Maybe next year...

                                            Just finished another film transfer project and the same thing happened ike it did last time in my previous post and I isolated it to the first reel again. Problem this time is that rerendering that preview file didn't fix the problem. Hope they didn't sneak some update to Premiere CS6 that I didn't realize I was installing.

                                              Actually, it's more than just one reel this time. Out of the 17 reels I had in the timeline, Premiere couldn't find the Preview files for 9 of them when exporting.

                                                I just tested the feature in CC and it still works just fine.  Without previews a 4 minute clip took 12 minutes to export.  Using previews (the new DNxHD in this case), the export took about 4:30.

                                                  Here we go again, you also said that this was never a problem in CS6 and it obviously has been a problem for other people in this thread with a repeatable solution. You also didn't state if the Renderer was in GPU or Software mode since it does work in Software Only mode as a workaround.

                                                   

                                                  In CC, I just tested a single 25 minute clip with 3 filters, a title and rendered it with DV preview files. With the Renderer in GPU mode a DV AVI export, with the Use Preview Files checked, took 33 minutes. Switching the Renderer to Software Only mode, the same DV AVI export took 4 minutes.This is the same thing that happens in CS6.

                                                    small effects on the timeline that was around 56 seconds long, I checked

                                                    the match sequence settings box for my export and the export took about

                                                    20 seconds. After that, I tested with it rendered, and checked use

                                                    So yes, it worked in my case with GPU. Unfortunately I don't have any

                                                      This is still my experience, as well, using an HP Z800 in CS6 with mostly Canon DSLR footage and AVCHD from a Panasonic AG-HMC40. I have to export without GPU acceleration in order for preview files to be used. It is necessary for me to use preview files when I have rendered linked AE projects in the sequence, which is often. I see no point in waiting endlessly during export to re-render these CPU sucking clips when time is of the essence. I'm grateful that cavemandude shared this workaround.

                                                        I would do a more substantial test that took longer than 20 seconds to render without using previews and preferably multiple clips with multiple filters applied to each. You also didn't test the time it took in Software Only mode. This is a test with machines that have GPU and CPU Renderer options. You also didn't state whether you were using CS6 or CC. By the way, it still works fine in CS5.5 this problem started wtih CS6.

                                                          I was referring to CC not CS6. I guess the real question is has the bug

                                                          you guys are experiencing been fixed in CC. For cavemandude it seems not.

                                                          I realize 20 second exports isn't optimal. I was trying to test before I

                                                          left for work where my mac pro's gpu does not support cuda.

                                                           

                                                          I did not also test software only mode, but your issue wasn't in

                                                          software only mode. It was in GPU mode, so that is what I tested and it

                                                          worked for my formats and sequence settings. That is part of why I am

                                                          wondering, is this a pc/mac thing, a codec thing, a card thing, or what.

                                                          Please go over your exact sequence and clip settings in your latest

                                                          tests. I'll try to help you out and test on my end and see what i can

                                                          come up with.

                                                            One thing to look at is your hard drive activity light. If it is properly accessing the preview files when exporting that light will be constantly on throughout the entire export process. When it doesn't work, that light will just sputter on and off since it is going back and rerendering all the effects again on the file/files in the timeline and that requires much less hard drive activity.

                                                                Another project completed and CS6 can't find all the preview files when exporting. Now I can isolate some of the Preview files using the work area bar in the timeline then exporting those but that takes time to test which ones work, use the Software mode, and then having to export ones that don't in GPU mode.

                                                                 

                                                                Funny thing is the first preview clip in the timeline hangs up just like on the last project I completed in CS6 after installing Premiere CC. So it looks like the installation of CC has messed up me being able to rely on the workaround using the Software Mode since I've completed many projects throughout the year using CS6 and never had this happen until right after I installed Premiere CC.

                                                                 

                                                                I'll be getting another editing PC in next week and will be only installing Premiere CS6 on it, no CC stuff, and then edit another project using preview files to check the results. Hopefully that will solve the problem.

                                                                 

                                                                Premiere CC has the same problem and as a bonus it also no longer has 0-frame accurate chapter points (when exported from the Premiere timeline) so that is why I'm using CS6.

                                                                 

                                                                At this point I could go back to using CS5.5 and never have a preview/export problem for projects that needs to use preview files. I can even be in GPU mode and not use the workaround.

                                                                  Doing a little more testing on single files. When in the GPU mode, I'm finding that a single video clip renders out pretty fast and this is why people that test with only one clip think that nothing is wrong. I typically have 20 to 40 clips, all rendered with color correction and one title layer, before exporting the entire timeline using the Preview files. So if you are going to do any testing make sure you have at least 20 or more video clips rendered in the timeline not just one or even two since the problem is with many clips.

                                                                   

                                                                  Just to add some more to this, I'm exporting a single 3-minute clip in GPU mode now, with Preview checked, and it is taking just as long as it did to render in the timeline which was about 5 minutes. And the reason a couple of the other single clips exported so quick was that they only had a sharpen filter on it and no color correction filters so it makes sense now why those were exporting so quickly.

                                                                  • 70. Re: "Use Preview Files" works in CS5.5 but is "Useless" in CS6

About 1 hour 30 minutes to get it ready to export the MPEG-2 file.

                                                                    • 71. Re: "Use Preview Files" works in CS5.5 but is "Useless" in CS6

After doing color correction, export clip as a DV AVI file to later bring into a new timeline to add chapter markers and then export to MPEG-2 to make a DVD in Encore.

Tested individual clips first and exported each as DV AVI to match the Preview format and it found the previews for each clip and took less than 10 seconds to export each 3 minute clip when doing one at a time. I then did an MPEG2 Export with Chapter Markers on each clip, so 22 Markers, and again it found all the Preview files making a single MPEG2 file.

I open and close projects all the time since I'm jumping around between various projects.

Then I'll close it and test again, even reboot and test again and see if Premiere can still find all the Preview files.

                                                                            • 75. Re: "Use Preview Files" works in CS5.5 but is "Useless" in CS6

                                                                                Export using previews took 3:38

                                                                                 

                                                                                Very clear evidence that PP is using the previews.

                                                                                 

                                                                                I want to make sure we're talking about the same thing here.  This is an issue about Premiere Pro losing preview files.

                                                                                I do not sufffer from that issue.  I've been testing from a position where PP knows exactly where all preview files are, even after reopening, and in all tests, PP uses the preivew files as expected.

                                                                                  An export using previews files for a short 3:14 sequence should only take seconds not minutes if it is actually using the Preview files. My 3-minute export tests took under 10 seconds when finding the Preview files.

                                                                                   

                                                                                  A true test of using Preview Files is to export in the same exact format as the Preview File render format used in the timeline so that no encoding to a new format occurs which can skew the testing. When it finds the Preview files it is simply transferring those files into a single clip, no encoding into a different format. I use the DV format for my Preview Files so I export a DV AVI file for testing.

                                                                                   

                                                                                  For example, I just exported a 50 minute sequence consisting of 22 video clips in the timeline in under 3 minutes that resulted in a 10.3GB file. That's the kind of speed you should be seeing for true Use Preview File exports in any format not that it took longer to export than the sequence length. And remember, that was done in Software Mode not GPU mode since it won't work in GPU and has been confirmed numerous times on both PC and Mac platforms.

                                                                                   

                                                                                  And saying that you've done all the testing in GPU mode tells me that you really don't understand what's going on here.

                                                                                  • 78. Re: "Use Preview Files" works in CS5.5 but is "Useless" in CS6

                                                                                    Those are very disappointing figures with those test settings, dude. Either your system is not properly tuned, or you are only using single disks. You could easiliy improve on that.

                                                                                     

                                                                                    BTW, using previews on that test means jack. There are no previews created on DV material and exported to DV. All you are measuring is disk speed, no GPU, no Use Previews, nothing but disk speed and that is pretty disappointing.

                                                                                    • 79. Re: "Use Preview Files" works in CS5.5 but is "Useless" in CS6

                                                                                      Please read my previous posts, I've always been using 1080 60i AVCHD files from my GH2 in the timeline and DV preview files since I started this thread to my most recent testing. Even if I had been using DV material, I'm doing extensive color correction with multiple filters that requires rendering and would create preview files that I could use during export and not have to rerender. Any DV files used in the timeline have been to simulate Preview files for some specific tests not for actual projects that I'm working on.
