4 GB file size bug and No Audio on render output with Lossless Ut codec and Lagarith ?

System :
Win7 x64
NTFS Raid 0 Drive
SpeedGrade 2014.0.1
******BUG******
Cannot render correctly using Ut lossless codec or Lagarith. Probably due to 4 GB size limit bug.
Steps to reproduce bug:
A single PAL 25 fps ProRes 1920x1080 clip, 4 minutes long which contains 200 cut/scene changes.
Split using scene changes detect.
Choose "split clip"
Applied looks (most of the time, i just use default cinematic 2 with a little bit adjustment)
Render using lossless codec above.
Results:
Rendering using small duration (10 seconds) on both Ut and Lagarith, there are no sound produced, although the video render correctly.
Render the whole clip (4 minutes)
On Ut :  The result render is messed up, the clip were overlap, or sometimes it's just resulting a garbage video (blank screen with no sound)
On Lagarith :  Unplayable video (crash to playback/open either in media player or in Adobe Media Encoder)
Expected results:
The video render result from lagarith and Ut "stuck" on 4 GB file size.
The problem was not occurred if using different codec (Animation lossless), even can produced 18 GB of clip which can playback fine and with audio.
Note :
I also have report the bug (?) in feature/bug report Adobe web page.
The current workaround is render using Animation (but i don't like it, the size were too big, i cannot export my long project using this codec)

I think that means you get separate video and sound files (but, I don't do BluRay, so could be wrong)

  • How can I auto export a PDF File using the "Smallest File Size" preset and set the Exported File Name based on information from an Imported PDF?

    Greetings all,
    I am trying to create a script to automate a PDF export process for my company for inDesign. I’m fairly new to inDesign itself and have no previous experience with javascript, although I did take C++ in high school and have found it helpful in putting this code together.
    We have an inDesign template file and then use the Multi-page PDF importer script to import PDF files. We then have to export two version of each file that we import, then delete the imported file and all of the pages to reset the template. This has to be done for nearly 1000 pdf files each month and is quite tedious. I’m working on automating the process as much as possible. I’ve managed to piece together code that will cleanup the file much quicker and am now trying to automate the PDF exports themselves.
    The files are sent to us as “TRUGLY#####_Client” and need to be exported as “POP#####_Client_Date-Range_North/South.pdf”
    For example, TRUGLY12345_Client needs to be exported as POP12345_Client_Mar01-Mar31_North and POP12345_Client_Mar01-Mar31_South.
    There are two templates built into the template file for the north and south file that are toggled easily via layer visibility switches. I need to get a code that can ideally read the #s from the imported Trugly file as well as the Client and input those into variables to use when exporting. The date range is found in the same place in the top right of each pdf file. I am not sure if this can be read somehow or if it will have to be input manually. I can put North or South into the file name based on which template layer is visible.
    I am not sure how to go about doing this. I did find the following code for exporting to PDF with preset but it requires me to select a preset and then type the full file name. How can I set it to automatically use the “Smallest File Size” preset without prompting me to choose and then automatically input some or preferably all of the file name automatically? (If the entire filename is possible then I don’t even want a prompt to appear so it will be fully automated!)
    PDF Export Code (Originally from here: Simple PDF Export with Preset selection | IndiSnip [InDesign® Snippets]):
    var myPresets = app.pdfExportPresets.everyItem().name;
    myPresets.unshift("- Select Preset -");
    var myWin = new Window('dialog', 'PDF Export Presets');
    myWin.orientation = 'row';
    with(myWin){
        myWin.sText = add('statictext', undefined, 'Select PDF Export preset:');
        myWin.myPDFExport = add('dropdownlist',undefined,undefined,{items:myPresets});
        myWin.myPDFExport.selection = 0;
        myWin.btnOK = add('button', undefined, 'OK');
    myWin.center();
    var myWindow = myWin.show();
    if(myWindow == true && myWin.myPDFExport.selection.index != 0){
        var myPreset = app.pdfExportPresets.item(String(myWin.myPDFExport.selection));
        myFile = File(File.saveDialog("Save file with preset: " + myPreset.name,"PDF files: *.pdf"));
        if(myFile != null){
            app.activeDocument.exportFile(ExportFormat.PDF_TYPE, myFile, false, myPreset);
        }else{
            alert("No File selected");
    }else{
        alert("No PDF Preset selected");
    So far my code does the following:
    1) Runs the Multi-Page PDF Import Script
    2) Runs PDF Export Script Above
    3) Toggles the Template
    4) Runs #2 Again
    5) Deletes the imported PDF and all pages and toggles template again.
    It’s close and much better than the original process which was almost 100% manual but I’d like to remove the Preset prompt from the PDF script and have it automatically select the “Smallest File Size” preset. and then if there’s a way to have it auto-fill in the file name so no user input is required at all other than selecting each file to import. (If there’s a way to setup a batch action for the multi-import script that would be even better!)
    Thanks in advance and if there’s anything else I can provide that would help please let me know! Even a nudge in the right direction will be a big help!

    If you hold down the option key, it will typically show the location. Or you can often hit option-return on the file and it will reveal the file in the Finder, instead of opening it.
    Final option is to open it, and just option-click the filename in the toolbar of Preview and it should show you the location.
    It's probably an attachment to an email you've received. If you have Mail set to cache emails and their attachments it'll be stashed in a subdirectory of ~/Library/Mail. Which is fine.

  • Hi - for any photo, info in mountain lion shows a different file size than Photoshop does. I've tested with CS3 and CS6 and get the same problem. Doesn't happen with CS3 and OSX10.4 or any previous versions of Photoshop and OSX. Anyone know why?

    Hi - for any photo, info in mountain lion shows a different file size than Photoshop does. I've tested with both CS3 and CS6 on 10.8.2 and get the same problem. This doesn't happen with CS3 and OSX10.4 or any previous versions of Photoshop and OSX. Anyone know why?

    this one is actually a really rare symptom of a flaky connection to the ipod on a Windows PC. there's more going on in terms of hardware on nanos and 5th gens than in the earlier models ... so if the connection is flaky to precisely the right/wrong degree, itunes will see the ipod, but misidentify it as an earlier version of ipod.
    tracking down the cause of the flakiness can be tricky ... as you already know ...
    just checking. have you tried connecting with a different (known-good) USB cable? does that seem to have any impact on the rate of occurence of the problem?

  • PDF reduce file size filters and CMYK to RGB conversion

    This doesn't seem to be on-topic to this forum, but I'm hoping someone here has the expertise to answer my question. We have some scripts which take a series of press-quality pdfs and use the "reduce file size" filter to prepare them for viewing on the web. We run these scripts on a 10.4 machine, and the filter works very well, reliably reducing file sizes of all sorts of pages.
    When we tried to upgrade the machine, we discovered that the quartz filtering has changed in 10.5 and 10.6. While it's usually an improvement, getting maybe 5-10% better compression ratios, it has become unreliable in that about 5% of my files fail spectacularly -- they blow up to 3, 4, 5, 6 times the original size.
    The other thing that happens is that the 10.5/10.6 filters munge the colors up. I found the solution to this -- in the ColorSynchUtility, make a duplicate of the Reduce File Size filter, and add a Color Management Component called Convert To Profile. This allows me to set a filter that converts the CMYK content to RGB. The problem is that there are about 40 choices of profiles, and it's not at all clear what I should use. Many of them have printer manufacturer's names in them, some say "Adobe", others have cryptic codes (probably referring to various RFCs and schemes). I've tried a couple of the ones that don't look like they are for printers, basically chosen at random. They all produce files of slightly different sizes for the reductions that go well, but on the files that blow up, some filters are better than others. (For example, I have a 5MB page which reduces to 1.4MB with the 10.4 filter, but blows up to 27MB with the "sRGB IE61966-2.1" profile, but only 12MB with the "Adobe RGB" profile.)
    So I have 2 questions:
    1) Is there any way to configure a 10.5/10.6 custom profile so that it behaves as reliably as the 10.4 "stock" PDF Reduce File Size works? It doesn't have to be the most wonderful compression algorithm out there, just so that it never or rarely has a file blow up in size.
    2) For converting press documents to pdfs that are going to go on the web, what is a good "Convert to profile" to use of the 40-some choices on the pull-down menu?

    Cathy,
    You have posted your question in a forum dedicated to the Final Cut Studio application Color. It is a very specialized program to grade (adjust) the color in video/film images. We know nothing regarding PDFs.
    Have you tried posting this on an Adobe support site?
    Good luck,

  • Increase redolog file size - Merits and Demerits

    Hi
    Currently, we are in  9.2.0.7.0 oralce version and having redolog file sizes (Mirrlog and origlog) of 100MB.
    Now we are planning to increase the size to 200 MB so that we could reduce the number of archive log files.
    Can you please let me know what would be the demerits of bigger size in redolog files?
    And also let me know the step by step process how to increase the size of redolog files?
    Thank you

    > I understand what you are saying but in our situation our backup policy is one time online backup  and one time offline backup in a week.....Online backup is on Thu and Offline backup is on Sunday.......
    >
    > In case of system crash if needed we would need to apply archive log files; If we have lesser number of archive logs; recover database would be faster.......correct me if am wrong.
    You are wrong.
    Ok, let's see an example:
    You took your backup on sunday midnight and your DB needs recovery on wednesday.
    Meanwhile you created say, 800 M worth of redolog data per day.
    That sums up to (monday, tuesday, wednesday) 3x800 M = 2400 M that need to be recovered.
    Going with your current setup (100 M redolog size) the largest archivelog file can be 100 M, makes 24 files to restore and recover.
    After changing the redologsize to, say 200 M, you only have 12 files to restore and recover.
    But know what? It's still 2400 M of data.
    Since you will likely not put every archivelog file to its own tape, but rather change the tape each day (just an assumption) or maybe don't use manually operated tapes at all, the little latency overhead in handling tapes doesn't count in to your overall recovery time.
    All in all you still need to feed the same amount of data to the recovery process.
    Apart from this:
    if you're discussing short recovery times, than you'd never perform just two data backups a week.
    You'd make online backups every day - maybe incremental ones.
    You' d use the flashback recovery area.
    An additional thing often overlooked: in many cases the ultimate performance killer for a restore/recovery scenario is not the technology in use.
    It's that when the case is there, the DBA is not sure anymore, what do to.
    He wonders:
    Where the good backups are.
    How to get them back from the 3rd party backup tool.
    How to check them.
    Where to get a different storage system because the original one is broken.
    How to figure out what needs recovery
    How the tools work
    By ensuring that you always master the theory and the how to of restore and recovery - that's how you make it quick and painless (and dataloss-less).
    regards,
    Lars

  • File size extremely high for .avi after render PE 9

    I'm very new to PE and have tried to learn quick to redact info (faces etc) in .avi files for a government agency. I was able to open the file (in the trial version) and make the track matte by dragging the original file to the timeline then dragging it again to the video 2 timeline for the top layer, Question 1) is this the same as copy and paste or am I doubling the size already? Anyway, I was able to get the matte and everything done. Now, to Render and save... I choose computer/avi again (I need to keep it the same) and it took 1 hr 45 min to render it, that seemed long to me but maybe not... but mainly the file size was then 100,883 kb! Starting with a 29.7 kb file. This is what my question is about....could this be right? I can't use it if this is what I get. So, here are the particulars as I got G-spot and looked it up, as per serveral suggestions I saw here. I'm trying to understand the CODEC info but I fear I have a ways to go before I can figure out what I did wrong. (This is my test computer, the future work would be done on a newer, better computer).  The videos I would be working with come from various sources and will vary in length but will probably all be a kind of avi.

    I appreciate any help you can give

    Thanks for you response and the information was very helpful. I was able to choose and output that gave me a good file size and I do want DV-AVI (I don't remember what I chose but it worked) but, I don't see an option for DV-AVI - is that a general DV output selection, because there seem to be numerous (AVCHD, NTSC, DV STANDARD) acronyms (I have tried to understand what each is) which do I want?

    For the use of Track Matte Keying, with say a Gaussian Blur, or maybe Moasic Effect, if you have not altered the In & Out Points, then just dragging the Asset to both Video 1 and Video 2 will work fine. If you HAVE adjusted the In & Out Points, you can just click-drag from the Source Monitor, where you set those In & Out Points, and all is good. The Copy/Paste is just another way to do it.
    As you are doing an "overlay," the output File Size will not be affected in any way. You are also limiting the Blur, or Effect on Video 2 to just the area "exposed" by the Track Matte, so the pixel count will not be altered.
    As Steve points out, the output CODEC in the AVI will determine the output File Size. File Size is basically determined by the Timeline's Duration and by the Bit-Rate of the output file. With DV-AVI, that Bit-Rate is pretty well set, and your Timeline determines the Duration. At ~ 13GB/hour, a DV-AVI will be pretty large, but that is the nature of the beast. Also, and as Steve points out, if you are going to do additional editing, and will be Importing that file into a New Project, DV-AVI is about as good, as it gets.
    Good luck,
    Hunt

  • PSD files sent over FTP given 1kb file size, archived, and have .bin appended to extension

    I'm trying to deliver PSD files to someone over our server's FTP. If the FTP shared folder is accessed via a browser (like safari which is the main thing I've been testing on), the files in are listed as being only 1kb in size when each is approximately 60MB and all have had .bin appended to the .psd file extension. When the file is downloaded it's still 1kb and when opened it is associated with the archive utility which attempts to unarchive it and produces and identically named and extensioned file of 4kb size which cannot be opened by preview or text edit or photoshop.
    Changing the extension does not help as suggested here http://forums.appleinsider.com/archive/index.php/t-25119.html . Also if the file is downloaded via 3rd party FTP software like cyber duck, though the file size is listed as 1kb, the correct size file is downloaded though still has the .bin extension. When this full sized .bin file is opened, archive utility instead of unarchiving attempts to archive it and produces a file roughly half the size which too cannot be opened. Speaking with apple care resulted in the suggestion that I use terminal command line to force the client to use binary mode when downloading the file which also downloads a file of correct size but with the .bin extension and that can not be opened.
    Is this a known issue with PSD files? I've not come accross this before, the server is configured correctly and different file types are successfully downloading with no changes to size or extension and then opening as they should upon receipt at the client side.

    Hi and thanks,
    that was my next port of call but I stumbled across a more permanent fix. Mac OSX server automatically converts files sent over FTP to something called MacBinary on the fly and it seems this process doesn't agree with PSD files. Someone else encountered this problem back in 2003 and found this solution
    http://forums.appleinsider.com/archive/index.php/t-25119.html
    speaking to apple care they also sent a link for the official mac instructions for achieving the same thing here
    http://support.apple.com/kb/TA20996
    and here
    http://support.apple.com/kb/TA20645?viewlocale=en_US
    in the second explanation it's important to note for anyone attempting to follow this that if you're fixing the problem on MacOsX server rather than just MacOSX it isn't necessary to enable the root account as it is automatically enabled by default. Simply log out and log back in as root and use the same password as the first administrator account you set up when the server was first configured.

  • Get texture file size, resolution and type.

    Hi!
    My script parsing every layer of AE Composition and creating the list of used textures (files).
    Then copy files in one folder.
    But I would also to compute overall size of all files and to warn user if he break the limit (for example, 10MB for all textures).

    2. texture resolution.
    3. texture color depth (is it 16 bits, 32 bits etc...)
    4. actual type of the texture file (.tga, for example). I mean exact type detection, not extension recognition.

  • Exported Wraptor dcp File-Size difference and quality loss

    Hi,
    I am currently working on exporting a short trailer (45 sec) to wraptor-dcp with AME straight from an After Effects project.
    In the export-preferences the estimated files size is about 8000MB (check out the screenshot).
    But the finalized dcp only has a size of 180MB. That irritated me so I downloaded a demo of easyDCP to check the material. The dcp is working fine but the quality is a mess even in comparison to a small mp4 (take a look at the second comparison screenshot: dcp left and mp4 (H264) on the right). Gradients are destroyed and chunky.
    Also with the color transformation off, the colors feel dull and only fit if I choose 'X'Y'Z » R'G'B (P3). Should it be that way? How can I enhance the quality of the dcp?
    All the best,
    Jay
    1 Export Settings (I just choose the wraptor setting in AME '2K Digital Cinema Flat' and did not change any settings)
    2. Comparison dcp / mp4 (H264)

    Will there be a new update coming soon?
    Problem: Wraptor DCP will play on GDC-TMS 8.0 at one theater and will not play at another theater running GDC-TMS 9.0
    Identified: Xsize/Ysize problems when reading on GDC-TMS 9.0. XOsize is wacked!

  • File size, importing and tagging issues in making form accessible

    Hello:
    I'm needing to import a Word document into either Adobe Pro X or LiveCycle ES2 v9, while making the form accessible to screen readers. The problem is that the source Word document is 405kb and is a 17 page application form with various sections that were created by using complex tables that contain checkboxes and text and no use of Styles.
    I've since been trying to tag the document myself, but, it looks like all of the content then needs to be tagged for the screen readers to pick up (tried running Read Out Loud, and the non-tagged info was not read), but not 100% certain. Also, it may increase the file size. Only on page 1 and its alread 900kb with tagging.
    I tried importing the Word source document into LiveCycle and received a 1073741819 error and it would not import. \
    If anyone has any insight on how I might import a complex Word form into Adobe Pro X or LiveCycle, tag it for screen readers, and keep the file size accessible, I would appreciate it.

    You can apply at text within Acrobat Pro. In the Tags pane, right click the applicable tag and select Properties. You will see the Alternate Text field on the Tag tab of the Object Properties. There may be other, possibly better solutions such as marking the special characters as artifacts, and applying OCR to the text-as-image - hard to say without seeing a sample document.
    Read Out Loud is not the best tool for checking accessibility, by the way. With 900+ documents to deal with, you might want to try using a screen-reader-emulator such as the one built into the free PDF Accessibility Checker (PAC) 1.3 (http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac/dl132.html)
    Hope this helps.

    You say, if you use 1024 x 768 images... that's just it: I'm just using the images without resizing. Some may be 4MB files when dragged in; others may be 300kb. I am not doing anything to them. Should I?  Does that help? Or does IBA "handle all that" when I drag and drop?
    It's not well documented. I get the impression that, if you drop an image that has resolution higher than 2048 x 1536, it is down-sampled to that size. You should at least crop the image outside IBA before dropping it in. If you want to save space, down-sample the image first to 1024 x 768 (after cropping).

    Also for the video: we're using iMovie and we just "Share" to iTunes and choose Large. Should I be choosing a lower setting or, again, does IBA not care and will take the Large and resize it?
    Instead of sharing to iTunes, export the movie to iPad format (File -> Export) and select 640 x 480. That'll give you reasonable quality at around 12 MB per minute.

  • Recovered data show normal file size but icon is different and wont open

    We recently had an old lacie drive go bad. got dropped one too many times or whatever.. not our fault but its for an important client.. drive had 200 GB of files.. a lot of stuff.. we took it to recovery and returned 80GB.. not bad.. among the recovered files were the ones we wanted.. and more... more than half retained their full file name.. so we know... but usually the icon for audio file is two red and blue waves. when we saw the icons that we had tried to save on the main computer they were black and white. but they still portrayed
    37.6 MB.. like a full normal file... on the recovered data we see the same file size, but the icon is a blank paper with the corner folded over.. we try to import it to pro tools but it wont import.. i think it was recorded in logic but i doubt that matters.. its just audio... im sure the proper info is in there but we have to get the applications to recognize it.. we tried opening it in different apps, but it simply wont.. is it an extension problem? will restore fix it? how should i do it? i appreciate any help!

    i tried changing the extension. i changed the icon but it still wont open. the files are sd2f. apple info will not allow a test sounding. sample and bit rate are not displayed. i gotta get these to open up. what should i do?

  • Need to export Movie to Quicktime Movie w/ similar file size and quality.

    Let me preface in that I am not in the video editing profession. Many times I have exported my work to the professionals. I'm sure knowing what you're doing is half of the battle. Here is my dilemma. First, I'm using Quicktime pro just to add a text track to the movie. I  then save the file as what Quicktime pro calls Movie .mov. This looks good and has the quality of the original .mov and the small data size. However, no other player than quicktime will recognize the text track. I then tried exporting from Movie to quicktime movie format (still .mov, can anyone explain the difference of the two .mov types???), but I find that the image quality is poor. Yet, in the quicktime format other players (except windows media player) recognize the text track. By poor quality I mean that I think what I have is the blocking effect. I assume that this is due to the bitrate being to low. Again, I would like to keep the file size low and managable for data storage and downloading purposes. I was hoping that in the end all video players would be able to have no issues.
    My current file sized are all less than 1MB and are of good quality.
    Just adding a small test track the Movie .mov is still less than 1MB
    The size of the image is 512x512
    I should also say that I'm a PC user with a quicktime pro windows version. I'm sure that doesn't help me one bit!! However, I believe my issues are more with the fact that I'm not experienced in compressing files and knowing exactly the right settings.
    Here is what I've tried thus far. Movie to quicktime movie
    H264 codec
    Current for fps (Which is in the original is 8fps)
    Key frames automatic
    frame reordering checked
    I've tried Automatic data rate and setting the bit rate, even at 2000kbps (the quality is low). My original movie with the highest kbps is only 1151kbps and has no artifacts
    encoding Best quality multi-pass
    custom size 512x512
    deinterlace checked

    am i correct that this 'my photo stream' process is not removing any image data?
    Yes,  as long as you have iPhoto's iCloud preference pane configures as follows:
    You're be getting the full image file, pixel dimensions, etc. which is essentially a bit by bit copy of the photo on the Phone.
    When you add tags and other metadata and export the file out of iPhoto as a jpeg with the checkboxes selected to include that metadata there will be some image compression.  However, if one chooses High or even Medium JPEG Quality one will be hard pressed to detect any image degradation unless printing very, large prints or otherwise displaying the image at a very, large size.
    I ran a test on a 1.4 MB photo from my iPhone  and compared the original to two exports, one at High and the other at Medium JPEG Quality and got these results:

  • OCR and Reducing file size

    I have a large document (a book) that I am trying to scan. I will be scanning it chapter by chapter. The book was printed in grayscale, so I don't have a pure BLACK AND WHITE document. I would like to optimize the file size, but I have a few questions about that.
    Currently running:
    Windows 7
    Acrobat Pro X
    Epson GT-S80 High-speed scanner
    1. What is a good typical workflow? I have tried scanning the documents to PDF using the scanner's software then opening them up in Acrobat to OCR them. I have tried using Acrobat's Scan feature with OCR being one of the steps in the scanning process. I have tried letting both softwares do their own color mode detection, where they will mix black and white and grayscale to reduce the file size, but have typically told it to stick with grayscale because that gives me the cleanest and clearest document. Does anyone have any recommendations on getting a good quality image and using a mix of black and white, as well as grayscale, or should I keep using just grayscale?
    2. I am having some trouble, I think, with the file size. I have a 12 page document I believe was either scanned at 300 dpi or was scanned at full resolution because I used CLEARSCAN, and downsampled everything to 300 dpi. I don't remember exactly, but that file is about 2.20 MB in size, and I think that runs about 185K per page. I would think there could be a way to get a smaller file.
    3. For text recognition purposes, this document is not ideal because it is a collection of powerpoint slide sheets (2 - 3 slides per page), and in some cases there is text on top of image in the slides, and it seems very hard to discern.
    4. Once a document has been scanned, and OCR has been run on it, I was under the impression that the OCR is in a separate layer, and that (if Searchable Text is chosen), you basically have a scanned image with another layer of searchable text. Because the OCR'd text is "there somewhere", is it possible to remove the scanned image text, and have just the raw recognized text, similar to if I created the document in Word, and created a PDF?
    5. Sort of back to number 1, suppose I am stuck with leaving the scanned image behind, and just running OCR, what is the optimal way to reduce the file size of the PDF? I had read that running your scan at 600 dpi may help with the text recognition. The same article suggested doing the higher resolution scan and using the ClearScan because it would  a) recognize the text better and  b) convert the text image to actual text and reduce the file size. From there, should I then just run the PDF optimizer to downsample the images to a certain DPI to further reduce the size?
    Hopefully you all can understand what I am saying and help fill in some gaps.
    Thanks,
    Ian
