    Export video with Lumetri effects - 2 to 3 videos render fine, after that flickering, colored frames

    the-ill-o

      After I spent 45 minutes waiting to be transferred to to right department with the support chat, only to find out technical support isn't available during the hours I called, I am going to try this outlet to get some advice:

       

       

      I have about 50 video files to export, each 20 seconds to 2 minutes long. They all have Lumetri effects on them (I suppose that's what causes the problem).

       

      I can render 2, maybe 3 videos without problems. The next one might be fine for a while, but then all I get is strobelight frames, flickering, and different color frames. One time I even received a blue screen of death. I restart Media Encoder, add files to the queue, same thing happens. 2 - 3 will work, after that it exports garbage.

       

      I am using Premiere Pro CC to edit the video, Media Encoder CC to export it.

       

      The original footage is HDV 50i - 1440 px by 1080px - 1.333 pixelr ratio.

       

      Besides some dip to black and cross transitions the only other effect is a title layer with some static color effects on it, and 2 Lumetri effects (warm midtones and dream 1).

       

      I thought at first maybe it is because I encode in FLV, 1800 mbps, but also when I used uncomressed AVI with the same settings as the original footage the same problem occured.

       

      I have two ATI radeon HD 6950s 1GB in my pc hooked together with cross fire, 16GB ram, the project file is on a SSD, the raw footage on a HDD. AMD Phenom II x4 processor with 3.4 GHz.

       

      OS: Windows 7 64bit.

       

      I did update to the latest GPU driver last night - that didnt fix the problem.

       

      Since I noticed the fans becoming quite loud during rendering, I did put two Ice packs from the freezer on top of the case and pulled it away from the wall a little bit to allow for better cooling (and it did stay a lot cooler with the ice packs).

       

      I do also get funky looking frames inside Adobe Premiere after trying to watch the footage with the Lumetri filter for a while. I'll have to restart the program and it'll work fine.

       

       

      Any suggestions what I could do? Settings, or something? I dont want to attend to my machiene for so many hours, importing 2 video files at a time, having to review each of them for errors. I'd rather set it up once, and let them all render...

          Srishti from tech support was showing me how to change the setting from Open CL to Software rendering.

           

          In Adobe Premiere go to

           

          File -> Project Settings -> General -> Video Rendering Playback

          Set this to Software only.

          Then it'll ask to delete all the Preview files, say yes.

           

          Now everything works, only it is much slower...

           

          But hey, at least it works!

            There are problems rendering Lumetri using OpenCL.  Switching to software mode or changing to nVidia are the current solutions.

              Hi,

               

              Sorry for the troubles. I have a few questions.

               

              - Was there a specific Lumetri effect that caused the problem or multiple effects? Which one(s)?

               

              - Did you apply the Lumetri effect to the clip or on a adjustment layer?

               

              - Did flickering only occur on the clip with the Lumetri effect and in a specific place or was is random?

               

              - Which drivers did you use?

               

              Thanks! You information will hopefully help this issue get resolved.

               

              Best,

                @Jim Sinon: Oh what a bummer.... I hope Adobe/Lumetri will support AMD cards, soon... Thanks for letting me know!

                  @Peter Garaway:

                   

                  Thanks for the response.

                   

                  I use two Lumetri effects:

                  1. Warm Midtones
                  2. Dream 1

                   

                  Both applied directly to the clip of raw footage which is in the sequence that gets exported. There is actually one sequence, where I fixed some of the footage putting it into another sequence first, then the sequence into the final sequence that gets exported.

                   

                  All my clips have both Lumetri effects applied to them. The flickering took place randomly, but it would definitely get worse the more I attempted to render (the first 2 to 3 no problems, on the 3rd or 4th maybe a few flicker seconds in the middle, any more would be 100% flickering - if any flickering or only like a green solid...)

                   

                  Now Shrishti from tech support insisted the problem was within the sequence. And that kind of made sense, because once we successfully rendered one sequence, there would be no more trouble rendering it a second time, even if the program was already in flicker mode. And also for some reason while we were playing around with it when one sequence failed, even after restarting Media Encoder, it would fail again afterwards.

                  However last night after it failed I would just try again, doing 2 at a time and it would be successful.

                   

                  Now I say it failed, but of course no errors no nothing... Just as in the result didn't look the way it was supposed to.

                   

                  Also I want to mention that especially when I kept it running after it failed (meaning you leave it runnning, producing only garbage) the fans of my computer kept running louder and louder. Not sure if it was the GPU or CPU. Rigth now it keeps rendering in Software mode and the fans are barely louder than under normal usage.

                   

                  I use the AMD catalyst driver which I downloaded from here:

                  http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_win8-64.aspx

                   

                  While Shrishti was trying a couple of different settings at one time the screen went dark, as it came back on there was a message coming from the windows tray, saying the display driver had crashed, but recovered. One time I also received a bluescreen message, which I will try to attach to this post.IMG_20130806_230035.jpg

                   

                  well i guess it doesnt have too much information on there other than... what is that? a memory address?

                  This happened I believe after the first attempt with the updated driver (I updated from 13.3 to 13.4 )
