Slow rendering in Media Browser

Love the new media browser in Premiere CS6, but when viewing video files (avchd) as thumbnails so I can use the scrubbing, it takes FOREVER for the thumbnails to render, especially if the folder contains more than 10 clips.
The behavior is bizarre: it starts rendering the thumbnails, then after 10 or so renders, the whole process starts over again. The second time, the original 10 thumbnails will render quickly and then it will render an additional 10 or so that will render slowly, then the whole process starts over, ad infinitum.  I have one folder with over 100 short video clips and this render process keeps looping and looping for up to an hour before all the thumbnails in the folder get rendered . . .  weird.
Has anyone else noticed this behavior??

I can understand your frustration, and I have elevated the priority of the open issue.
The problem occurs when trying to preview many files (like, 100's) at once in the media browser. So the workaround is to view them in the media browser in smaller chunks, by sub-direcorizing them beforehand OR just importing them all and using the project panel/icon view for preview. Also, as I mentioned, we have the product 'Bridge' (which you should already have if you installed any of the suites or the prpro family prodcut) which is made for this sort of high-volume file previewing before opening them in any of our apps.
Is there some reason why non of those workarouns is sutiable. Is there anything else I could realisitcally do at this time to rectify your problem?
Well, I appreciate the workaround suggestions, and they do work, of course, but the productivity drop is extremely significant and not on par with the stated improvements in CS6 that prompted me to pay Adobe big bucks. (to me anyway)  :-)
For instance:  Viewing in Bridge does work properly, as I have tried that.  Of course I can't scrub (the big draw in CS6)  And I'd have to sit down and make a list of all the files and their names so I could go back into Premiere and import just the ones I need.  Not very productive.
As for splitting the files up into smaller folders: the problem is AVCHD.  Have you tried to move all the pertinent files for each stream from all the different folders to another folder and keep everything straight?  Yuck!
I suppose importing all the files into the Project is an option.  (and one I haven't tried)  But that would burden the project with a ton of unneeded cruft.  This suggestion is probably the most viable because I could set up a workflow to import all, then scrub through the files and remove the unneeded ones from the project.  (sort of a backwards approach)  Since I haven't tried that yet, I'm not even sure if that would workaround the thumbnail loop issue.  And that would make the initial project HUGE.
Here again, I think the anomaly I'm seeing is different from the one you're seeing.  Once that folder gets fully processed that first time, Premiere works just as envisioned from that point forward, ON THAT PARTICULAR FOLDER.  There is something else going on here.  Give me a day or so and I will try to throw a video up on youtube so you can see the precise issue.  I think you'll be surprised. First, I'll show how it works properly on a pre-processed folder.  Then, I'll show the anomaly.

  • Incredibly slow rendering in Media Encoder CS4 for Mac

    We're having a strange problem trying to render a Premiere Pro CS4 project in Adobe Media Encoder . We're doing a 720p H.264 file that is about 35 minutes long. On my macbook pro laptop it took about 24 hours to render. As an aside, the same sequence and quality level in our previous editing method using avisynth and x264 only took about 2 hrs, but that's another story.
    So, we figured we would bring in the big guns and render it on our 8-core mac pro desktop. Turns out it's estimating the render at 34 hours and the CPUs are 70% idle on average. So, what gives? What in the heck is wrong with Adobe Media Encoder that it is going even slower on our Mac Pro? We even copied all the files to our local 7200 RPM sata internal disc just in case the problem was due to a slow NAS device, but that didn't help it at all.
    We've run all updates, so we're running on the latest version of the encoder.
    Any ideas?

    OK, here is an update. The original estimate for the single-disk setup was up to 75 hrs before we halted it. This is way slower than my laptop doing the same thing, so I think something is wrong.
    We put in four separate 7200 RPM internal sata disks now: one for scratch files, one for video source #1, one for video source #2 (we have a sort of picture-in-picture thing going on on this video), and one for Premiere Pro to run from. Yet we're still seeing low CPU utilization and high time estimates.
    Any ideas?

  • IMovie audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !

    iMovie 11  audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !
    I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
    The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
    I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

    I have a fix - or rather, a workaround.
    WARNING: It is lengthy, but still far better than starting a new project from scratch.
    I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
    ...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
    It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
    This will require:
    A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
    1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
    2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
    3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too,  as they will be extremely helpful later.
    4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
    This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
    5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
    You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
    Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
    We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
    VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
    I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
    6.) Once you are done with this, export your newly pieced together audio track.
    7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
    8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
    9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
    Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
    YOU'RE FINALLY DONE!!!
    I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
    DON'T USE IMOVIE EVER AGAIN.
    I hope this helped!

  • Slow access of photos from Media Browser

    I have a computer with a small iPhoto library. Under 800 photos. iPhoto launches quickly, and effortlessly. iWeb launches easily, but when I try to access the Photos from the Media brownser...things bog down. The spinning ball goes for a couple minutes, before showing me the photos, and regaining control of iWeb. This slowness happens also from Garage Band (when accesing photos via the Media brownser). I rebuilt my iPhoto library database, but this didn't help. Any ideas?
    Thanks
    Ted
    MacBook Pro   Mac OS X (10.4.6)  

    Thanks John and Jim,
    Here's an update. I did not have iPhoto opened when launching iWeb. And the iMac Intel 20" has 1gig RAM.
    I first rebuilt the database in iPhoto...no help. I called applecare, and then first had me rebuilt the database (no help again). Then we created a new user, and the new user worked fine...no sluggishness in Media Browser. So we went back to the ailing user and removed the iPhoto prefs (no help)....then we removed ALL prefs (no help)...then they had me remove the entire user Library....and still no help. At this point, the 2nd level tech support said they didn't know the answer yet...and they are referring it to Engineering...and I should hear back in 2-3 days. I'm guessing they will have me backup, reformat, and reinstall from scratch...but we'll see.
    Thanks for your interest...

  • Premiere CC media browser too slow

    Hi guys,
    I'm having some problems to read RED files on media browser on CC.  It's too slow.  I ran some quick tests here.  In CS6, create a new project and chose a drive in media browser. It read the files in 21 seconds.  In CC, create a new project and chose the same drive in media browser. It read the files in 1 minute and 40 seconds.  I really enjoy editing in CC but this issue is killing me.  Does anyone have a clue?

    Hello VaughnByrd21,
    It's taking a half an hour to render 5 minute clips and over an hour to export them...sometimes an hour and a half.
    Can you post a screenshot of your export settings dialog box?
    ...it seems like Adobe has put us on the back shelf, and continues to crank out software that we desperately need but that won't run on a professional level on our systems.
    Have you adjusted the permissions of your Adobe folders? Updating OS X can change them randomly: Premiere Pro CC, CC 2014, or 2014.1 freezing on startup or crashing while working (Mac OS X 10.9, and later)
    NVIDIA drivers are not doing very well lately either with CUDA and Mac OS X Yosemite. For sure, switch both Premiere Pro and AME to OpenCL mode until they fix those drivers.
    These issues have more to do with OS X and NVIDIA drivers, nothing to do with Adobe applications—so it's not always our fault when things go wrong.
    You should also try deleting your media cache, which you can find in Preferences > Media (click the Browse button). That fixes a lot of issues.
    Please also consider trashing preferences and repairing disk permissions.
    Thanks,
    Kevin

  • Slow Media Browser to Aperture library

    Hi All,
    I'm just after migrating my entire iPhoto library over to Aperture (reference). Libraries are identical - exactly same number of pictures, events (projects), faces etc. Some about 25k pictures each.
    What i noticed however is, that when I use Media Browser (browsing for image in Safari or other programs), loading of media under "Aperture" is significantly slower than iPhoto.
    I can easily browse iPhoto resources shortly after opening Media browser, but it takes good 20 - 30 seconds, before Aperture resources are available for browsing.
    Any ideas on speeding this up?? Why would it be so much slower?
    Thanks in advance for any clues.

    It was broken in a recent Aperture update, and then fixed. The issue then was manually correctable by making certain all images had proper date metadata.
    I don't why it is now slow -- there may be some need for it to go find the last Aperture Library opened by A3, as only one will be shown in the media browser, even though Aperture can be used with several different ones. It is the last one opened by A3 that will be presented, I believe.

  • Share iMovieHD to Media Browser

    Previous posts in March, indicated the best quality was obtained by sharing iMovie HD to Media Browser rather than sharing to iDVD. Sharing to Media Browser was tested and compared to sharing iDVD. Sharing to Media Browser produced the best quality. When I am in iMovieHD and I select Share, the following options appear: Email, QuickTime, iDVD, eWeb,Garage Band, Bluetooth, iPad, Video Camera and Share. When I select Share, the next window shows icons for these selections? So, how do I select Share to Media Browser?
    I am using iMovie HD v 6.0.2 and iDVD v 7.0.4
    Thanks,
    Richard

    Hi Richard,
    In iMovie HD 6 you don't need to Share at all if you only wish to create a DVD in iDVD. The discussions about "Share to Media Browser" apply only to later versions of iMovie. The HD 6 version does not have this option.
    With HD 6, all you need to do is _drag your movie into the background area of the iDVD Theme_ - be careful not to drop it into one of the Drop Zones. iDVD will render any items in your movie that still require rendering (e.g, slow motion) - most items (such as transitions and titles) will already have been rendered by iMovie.
    Avoid using "Share to iDVD". In _some circumstances_, this will produce "jaggies" on stills - it's a well known bug in iMovie HD 6. A search in the HD 6 forum should highlight posts on this issue.
    Dragging the movie into iDVD will produce excellent results - barely distinguishable from your original DV material (if that's what you are using). I can't speak for HD material as I use iMovie '09 for High Definition footage.

  • Will Slow Rendering Time be Worth it?

    My iMovie project is 2:06:20 in duration. iDVD is very strict about only burning DVDs under 2 hours. I am rendering my iMovie project using "Share > Media Browser > Large". It is going to take some estimated 570 minutes. Is the time spent rendering the movie worth it? (And how come iMovie '08 seems so much slower and importing and exporting video? Is the quality much better?)
    If iDVD refuses to burn I've been told to create an image and burn it with toast or Final Cut Studio.

    Windows Server 2008 should already have CTCP enabled; but Windows 7 hosts might not.
    Using a module has the all the normal pros and cons.  So, cannot say a stand alone unit would be better, although the latter does provide you more selection options, including 3rd party.
    Normally, yes, you need WAAS hardware at each site.
    PS:
    Just increasing a host's RWIN will often allow it to push a LFN to capacity.  However, slow start really does become slow start when latency is high.  This can also be a problem if sending lots of little files, i.e. each one starts slow.  Small files might not even allow the transfer rate to reach full speed.
    Also a problem is standard TCP's adaptive flow rate, which increases very slowly when latency is high after a packet is lost.
    I believe there are file transfer utilities, that transfer a file using multiple TCP sessions.  This can greatly increase the transfer rate on a LFN.

  • Feature Request:  Standard Keyboard Navigation in Media Browser and Project Panel

    It's been a while since I've had time to submit a feature request.  I've wanted to see this one for a while.  If you agree, please submit your own feature request here: http://www.adobe.com/go/wish/
    System Navigational Keyboard Shortcuts in Media Browser and Project Panel
    Windows (and I'm sure Mac) has a standard set of keyboard and mouse navigational shortcuts for keyboard and mouse.  I'm so used to using them in daily browsing (both in Windows Explorer and in any web browser) that missing them in the PPr Media Browser, or getting a different result in the Project Panel, is still very jarring and slows my workflow (even after having used Premiere Pro [again] since version CS4).
    I propose that the Media Browser and Project Panel should honor the OS defaults for keyboard and mouse folder/file navigation.  A few of the standard (Windows) keyboard and mouse navigational shortcuts are listed below (listed in order of most helpful to my own work):
    Moust Back Button = "BACK"
    ALT + LEFT ARROW = "BACK"
    UP, DOWN, LEFT, RIGHT = steps through the various folders within the view.
    UP, DOWN walks through the directory tree while RIGHT expands the currently selected folder and LEFT contracts that directory (twirl down, etc).
    ENTER opens a folder.
    ALT + UP = "Folder Above"
    ALT + RIGHT ARROW = "FORWARD"
    F2 Renames a folder
    ENTER "takes" that name to the clip. (current functionality used ENTER to rename a file/folder).
    ESC cancels the renaming operation.
    Pressing Enter on any piece of Media or Title, etc should take an "expected" action acording to it's context.  (i.e. ENTER on a video clip would load it inot the Source Monitor.  ENTER on a Title would open it in the Title Editor.  ENTER on a folder would take us into that folder).
    These functions exist in both Windows Explorer as well as most modern Web browsers.  When browsing files and Project folders, it's what I've come to expect.  It's muscle memory, if not intuitive.  I realize that many of these keyboard commands are already in use in other windows/panels of the application, therefore, these commands should be Panel-specific (i.e. ALT+LEFT works differently in the Media Browser and Project Panel than it does on the Timeline/Sequence).  And as always, when making such changes (i.e. changing the behavior of ENTER to F2), this set of keys should be highly configurable based on preference:
    Preference:
    checkbox:  Use OS-specific navigational keyboard and mouse commands in Media Browser and Project Panel
    checkbox:  Use the (very few) "classic" Adobe keyboard commands in the Media Browser and Project Panel
    The most common habit I find myself doing in the Media Browser is clicking the BACK button on my mouse—only to realize, yet again, it doesn't work that way in PPr.
    The most common habit I find myself doing in the Project Panel is pressing F2 to rename a folder/bin.  Of course that doesn't work.  And when I've renamed it, I press ENTER to save the name, but that only moves me to the next folder ready to rename it, too.  I also find, out of habit, I try to navigate the bins using the arrow keys and then open the bin/folder using ENTER.  Instead, my bin is asking for a new name and I hit ESC to avoid renaming it—now THERE's a shortcut that works the way it should. 
    I realize this feature may be controversial to some, since it's not the way we're used to doing things in PPr.  However, I'm sure there are just as many out there, like me, who are confounded as to why PPr has never worked with the "conventional" navigation shortcuts found throughout the rest of the operating system, be it Windows or Mac.

  • Why am I getting an encoding error after exporting 4:3 to media browser?

    It seems that I have completed my iMovie, then exported it to media browser.  Once there I work on any them, tried multiple ones in old themes, and newer even trying to keep the aspect ratio at 4:3 ratio.  I continue to get an error message called, "Error during rendering/encoding of the menus/slideshows.
    I have never had this problem and it is very frustrating!
    Can someone help me?
    I even tried the straight iMovie to iDVD directly.
    Running Mac OSX 10.6.7
    I need to finish a wedding slideshow for a friend asap and am having NO luck!

    Hi
    Realy would want to be of help - but I can't see where the problem originates.
    I would - just to omitt the obvious
    • trash pref files - iMovies and iDVDs
    • run - repair permissions
    • Start a new - User account and log into this and see if things works better here
    • Free space on Start-Up hard disk > 25Gb - I never go under
    • Garageband-fix. Start it, Play a note and Close it. Re-try (Corrects an audio problem that hinders iMovie)
    • Screen must be set to Million-colors
    • Turn off Mac and disconnect Mains/Power for 20-30 minutes - will at least re-set FW-port
    • Third party plug-ins that doesn't work OK (not relevant for iMovie’08 or 09 or 11)
    • Problems in iPhoto Library can affect iMovie to crash on start-up. Re-build this first then try to re-start iMovie.
    This You do by
    _ close iPhoto
    _ on start up of iPhoto - Keep {cmd and alt-keys down}
    _ now select all five options presented
    _ WAIT a long long time
    • iMovie updated ?
    • QuickTime updated ?
    • Mac OS version ?
    Just to try to pin point the problem.

  • Share Media Browser - "Unable to prepare project ... error occurred (-108)"

    Finally got my sequence rebuilt after discovering bug/quirk with iMovie (details later). When sharing movie either via/Media Browser or "Export Movie" option after 10-15 min. get this exact message: "Unable to prepare project for publishing. The project could not be prepared for publishing because an error occurred (-108)." It plays wonderfully in preview (full screen or normal) from beginning to end. Any ideas?
    Bug/quirk discovered. Long time on this project. Had it exactly like I wanted, would generate movie and have mysterious background audio when video tracks were purposely muted. Playing within iMovie environment it worked flawlessly and would only show up in rendered movie. Also the background audio didn't match the playing video clip but was coming from other included clips elsewhere in the movie. BIG mystery. Tried breaking apart movie and re-doing. Still crept in. Finally discovered I had duplicate video files in the ./iMovie Events/ directory, "<filename> 1.mov". I surmise that iMovie is using the most recent duplicate, "<filename> 1.mov" which I was muting but the rendering process was using the original "<filename>.mov" clips. Still a mystery on audio not matching clip but it could be due the trimming I had done throwing the timing off. The duplicates happened when I had moved/copied video content in "Event Library" to manage disk consumption. It failed somewhere in the process and I ended up with duplicate video clips. The aforementioned quirk/bug still appears to not be corrected with latest update as it still occurs.

    Hi
    -108            memFullErr            Ran out of memory [not enough room in heap zone]
    My guesses are
    • Turn off TimeMachine during use of iMovie - use to set Heap Zone right
    • Turn off Mac totally and re-start - Frees up RAM
    • Secure a minimum of 25Gb free space on Start-Up hard disk - so that iMovie and Mac OS can store it's temp.files here. IMPORTANT

  • Error -50 when trying to share with media browser?

    I'm attempting to burn a dvd in idvd for the first time. When I click media browser under share in imovie 08, I'm fist told that there's missing media. A source clip is not available. Although I hear it (audio) in both the project and in the source material in the event library. I clicked continue and things started to move along then this warning came up UNABLE TO PREPARE PROJECT FOR PUBLISHING ERROR CODE-50.
    Please help.

    I'm using native.
    I did cancel all background rendering and exporting before I deleted the renders. I actually quit final cut before I did that, then restarted.
    I found that the crash was probably the result of a motion plug-in that I was using, but the speed of exporting is still way below what it was last week. I would still like to utilize that motion plug-in :/

  • Media browser should open a folder, but stucks, and giving an endless spinning ball

    media browser should open a folder, but stucks, and giving an endless spinning ball. How can I reset at startup Pages?

    What have you got in the folder?
    It may simply be large and numerous, with possibly graphics that need to be converted like .eps, .ai, .bmp etc and it takes time to open, particularly if you don't have enough memory on a slow machine.
