HD clips truncated on 1/4- & 1/8-speed import

All-
I'm on a 12" PB 1.5Ghz, 1.25GB RAM, running the latest and greatest OS X / IMHD updates as of today. Camera is a SONY HDR-HC1. The issue involves importing HD at slower-than-realtime speeds. As has been discussed, the capture is supposedly real-time but the conversion to AIC is slower. What's still unclear to me, and what I could not find an answer for in the discussion archives, is how to avoid clips being truncated on import. For example:
1. If, during an import, the iMovie "import" button is pressed when the tape reaches the end of the clip you're trying to import, import ceases immediately at the point currently displayed in iMovie. This is of course the AIC conversion point, which lags the tape, so the clip is truncated. So that's no good.
2. If, instead, during an import, the iMovie "stop" button is pressed when the tape reaches the desired point, the Mac pop ups a progress bar saying the remaining HDV cache is being processed. However, when this eventually completes, the clip is shorter than the target point on tape. It's closer, but still not there. Presumably the HDV capture process is not entirely real-time either.
3. The only way I've found to reliably capture the full length of any clip in question is to stop iMovie using the "import" button when the iMovie display itself shows that the AIC conversion process has reached the point you desire. While you're waiting, you must *let the tape run* way past the end of the clip in question. Four to eight times past the end, to be precise. Only problem is, it's unlikely you've got that much tape left. And if the camera hits the end of the tape before the Mac reaches the target point, the camera will automatically click off and iMovie will cease its import at that point. Yes, it will continue to process any remaining HDV cache, but if your clip is close enough to the end of the tape, the cache will not be enough to take you to the target point.
Anyone?

Oracle hasn't certified their drivers on a 1.5 JVM yet, so I wouldn't be shocked to learn that there was some sort of issue. I don't have a 1.5 JVM laying around to test with, though.

  • Updated to iMovie version 10.0 Opened it. All my clips and projects were there. Then it crashed. Now no clips no projects. If I try and import them they are dimmed. If I try and 'update projects and events' a dialogue box says no files found.

    Have macbook pro 2012, running Maverick. Updated to iMovie version 10.0 Opened it. All my clips and projects were there. Then it crashed. Now no clips no projects. If I try and import them they are dimmed. If I try and 'update projects and events' a dialogue box says no files found.
    Have tried restarting computer, no joy. Help!!

    The reply from Nerval fixed it. It is very simple and it works.
    If you have a lot of Projects and  Events, leave the iMovie running for a long time. I had 160G and it took 4hrs. It is doing it in the background so don't shutdown too quick.
    Thanks Nerval.

  • Truncate / Trim and Convert the values while importing in Import Manager

    Hi,
    I am facing the following issues while importing the values in Import Manager.
    1) The incoming value is a 4 character text value (e.g. D004) and i need to truncate the 1st two characters so that i get the output as "04"  and map it to the destination numeric 2 character field.
    Can any1 help me on this as to how can i truncate the 1st two characters?
    2) My incoming value is a numeric field which is coming from ECC. this value can be negative as well. the ECC sends this value as (78.00-) ie the minus sign is suffixed to the value but in MDM i need it as (-78.00) ie minus sign prefixed to the value.
    Is there any setting in Import manager where i can set the minus sign as a prefix?
    Useful answers will be rewarded with points.
    Regards,
    Roshani

    Hi Roshani,
    Can any1 help me on this as to how can i truncate the 1st two characters?
    As suggested by everyone, none of these options will work. Since your field has alphanumeric Value i.e. D004. Use Option Replace.
    After mapping your source field with target field which must be of Type TEXT, Right click on your source field>Set Value Conversion filter>Replace..-->a pop up window will come Replace write Find What: D0 and Replace with: keep it blank(dont write anything) and then Press Ok, you will see all your Source values D0XX converted to XX and then can save in Import Map which will give you the desired result.
    If you set your target field of type INTEGER, you cant have option Replace. And the TRUNCATE option as suggested by everyone will not work as Operand 2: you can set as Numeric values only, you would not able to write D.
    Is there any setting in Import manager where i can set the minus sign as a prefix?
    I dont think this is possible alone with Import Manager, you need MDM workflow for this where your workflow trigger action = Record Import in Data Manager, and need to select the same workflow in configuration options of Import Manager>Import>checkout/workflow = select the workflow name from drop-down which you set in Data Manager and then need to save this in your Import Map. So in this manner whenever record comes through import Manager, these records automatically will go through this Workflow and will give you the desired result.
    START(CHECKOUT)>Assign>STOP(CHECKIN)
    Assign step where you give assignment on this field and write assignment expression as:
    IF(FIND(XXX, "-"), "-"&LEFT(XXX, (LEN(XXX)-1)), XXX)
    where XXX = Field name which you defined in MDM repository.

  • AE is clipping a fraction of a second off my imported WMV footage, how can I stop this happening?

    Hi all,
    I've created a new composition using some WMV footage and I want to add a bit of adobe illustrator art on at the end like a closing title. I don't need to extend the length of the movie, the art can just lay over the top of the imported footage.
    The problem I have is when I import the footage (File > Import > File...) I import the WMV file and once inside the composition After Effects trims a tiny bit off the end of the imported footage where there's a fade to white then it ends on a black screen. It wouldn't be a problem if I wasn't losing part of someone's sentence as it fades out.
    Can anyone help me please?
    For further info, I've set fps to 25 which is the same as the imported footage and I've tried importing it into longer compositions. Oh and also if it helps I'm working on a PC using After Effects 7 Professional.
    I wonder if it might be something to do with the fade out in the imported footage???
    Many thanks in advance for any responses.
    KarlOSX

    The issue is most likely with the source file. The last keyframe interval is not complete and thus AE makes wrong assumptions about the clip duration because it stops at the last full keyframe. This usuall happens, if you use VBR encoding in the WMV files and leave everything at the Automatic settings. If you plan on using WMV files for your work in Ae, you should export them differentlyx from whatever otehr app you use, that is with a fixed keyframe interval and a constant data rate. As Rick said, though, re-editing already compressed files is not the best way to work, so if you have full control over the source material, consider otehr file formats, CoDecs and so on...

  • Making the scrolling credits clip longer did not slow down the speed of the text

    Lengthening the clip just left a lot of blank screens after the credits rushed thru. Any way to edit it?

    Ignore last post I figured it out i wasn't lengthening the actual title only the clip previously.

  • Clip quality gets severely degraded (appears interlaced) upon import?

    I am trying to import a clip into Premiere to use in my project but whenever I import it the quality gets severely degraded: http://imgur.com/JHVbl
    It looks this way both in the preview and after export but it looks fine when I view it outside of premiere. The clip is 720p mp4, the sequence preset I used was AVCHD 720p30.
    Any idea what I'm doing wrong?

    Creating a new sequence based on the clip results in the same behavior. Here is the set of steps I am currently following to reproduce this:
    File -> New Project
    - all scratch discs "Same as project"
    - Video Display Format: Timecode
    - Audio Display Format: Audio Samples
    - Capture Format: DV
    Video Rendering and Playback Renderer: "Mercury Playback Engine Software Only" (greyed out)
    New Sequence window pops up, clicked Cancel
    In the "Project" window I right click, select "Import...", doubleclick the file I posted on limelinx. "Rallycross 5 - Map Analog.mp4" shows up in the list of items.
    In the "Project" window I double-click the "Rallycross 5 - Map Analog.mp4", it opens up in the "Source" window.
    I set the zoom to 100% and scroll to the bottom right corner of the frame, the speedometer needle is distorted and looks interlaced.
    This is with Premiere Pro CS5. Considering the clip is distorted even within the "Source" window is it possible this is a codec something outside of Premiere that Premiere is relying on? When I open this clip in VLC it plays properly.

  • Lumix GH4 - AVCHD clips 16.5 hours in the past upon import.

    I have a Panasonic Lumix GH4 (firmware V2.0). I just discovered that all my clips shot in AVCHD have an incorrect creation date upon import into FCPX (10.1.4). All files have a creation time/date exactly 16 hours and 30 minutes behind the actual recording time.
    The clock on my camera is correct time. The date shows as being correct when I review the clips on the GH4. But when importing to FCPX, the date in the media import window shows the creation date as exactly 16.5 hrs in the past. I have tried this on my Macbook Pro, iMac and just returned from the local Apple store where I tried it on their Mac Pro, with a Genius observing the process. Exact same result.
    This ONLY occurs when the clips are AVCHD format. The GH4 offers AVCHD, MP4, MOV. All clips shot in mp4 or mov show the correct creation date. It is only the AVCHD clips that have this issue.
    For example, if is shoot short 3 clips at exactly noon (12:00pm) today. Quickly switching the format between the clips. Upon import to FCPX the mov and the mp4 show a 12:00pm January 26 creation date. The avchd clip show 5:30pm, January 25 date.
    This makes a total organizational mess when I have dozens of multi cam clips from other cameras that do sort properly by date.
    Has anyone else seen this ?

    Would someone mind just shooting a few seconds of video in AVCHD, pop out the SD card, and import media into FCPX and check the Creation date please. Any results would be appreciated. (BTW: This has to be v2.0 of the GH4 firmware).
    The attached pic are the Get Info on 3 files shot seconds apart. ACVHD, MP4, MOV. Note the creation dates.

  • IMovie 09 truncates up to 1 second at beginning of each clip on import

    When importing new video from my Canon HV20 (HDV), I'm noticing that the beginning of each new clip is missing up to one second of recording when compared to the source tape. If I were to import the same material using iMovie HD v6.0.3, the whole clip is imported. Any ideas?

    Same issue using an HV20 here also. Any resolution?
    I tried doing a manual import, but it still misses half a second or so of video from the source. I only tried to import the first clip, so I don't know if manual import helps with subsequent clips (when manual importing and letting the camcorder play to end).

  • Files copied using web folder clipped

    Hi!
    When copying files using Web Folder in I.E. 6.0 all files larger than circa 65 kb are clipped/truncated at some point between 65,000 up to 67,000 bytes.
    I'd apreciate any hints on this matter very much!
    Thanks!
    ORA-21000

    ok,
    let's try to isolate the problem.
    1) please try to get more error log information by raising the log level as described here: Re: http error log
    2) try to find the specific file, webdav complains about. Does is contain special characters?
    Can you post the filename here?
    3) try to set the browser language to en-us.
    I need some more information.

  • FCPX: Clips have dropped frames in timeline, but not in Event Library or VLC

    I make movie montages (or supercuts as they're more widely known) and I'm constantly running into this issue. Here's my workflow:
    1) Convert movie to .mp4 using Handbrake
    2) Extract clip from converted movie using MPEG Streamclip
    3) Import clip into FCPX
    In FCPX I have the project's framerate set to 23.98 at 1280x720. When converting a movie to .mp4, I set the framerate to 23.976 (NTSC) in Handbrake.
    - Clips play fine in VLC.
    - Clips play fine in the Event Library.
    - As soon as they're moved into the timeline, playback is choppy.
    This doesn't happen with all clips, and there doesn't appear to be any rhyme or reason as to why one plays fine and the other doesn't. What am I missing? What should I be looking for when comparing clips?
    Final Cut Pro X 10.0.6
    Mid 2011 Mac Mini
    Processor  2.7 GHz Intel Core i7
    Memory  8 GB 1333 MHz DDR3
    Graphics  AMD Radeon HD 6630M 256 MB

    You could do the MP4 to PR .mov conversion in Streamclip or Compressor.

  • No audio for clips in my event library since upgrading to iLife '09

    After upgrading to iLife '09, I noticed something odd in the new iMovie. All of my clips (recorded with a Sanyo Xacti HD1A and imported into the previous version of iPhoto DO show up in the event library, but DO NOT play any sound in the event library. If I copy a clip or move it up to the project editor the audio plays there. Does anyone know why I am getting no audio for these clips in the event library or what can be done to correct the issue?
    Thanks,
    -Mike

    Finally got some sound on the clips in my iMovie '09 event library. This is what worked here: I went into the Pictures folder and showed the package contents of the "iPhoto Library". I went into the "Data" folder. I went to a "2008" folder. I located the folder of the first video clip I had for the holiday footage... "Dec 14, 2008". Inside that was a QuickTime file "SANY0001" and a JPEG "SANY0001.jpg". I zipped up the "Dec 14, 2008" folder. I dragged the folder to the trash. I dragged the .zip file out to the desktop.
    I opened iPhoto '09. It showed an event for Dec 14, 2008 with a dashed-line round rectangle where it would have normally shown the first frame of the video clip. I closed iPhoto '09 and opened iMovie '09. It alerted me that it needed to generate a thumbnail for some video, and after about a minute the clip was in my event library and playing audio. Not only that... ALL clips in my event library now are playing audio. I quit iMovie '09 and went back into the "iPhoto Library". A new "Dec 14, 2008" folder was there with a new "SANY0001" QuickTime file (I wonder where it got this file from... hidden cache or backup somewhere?). I expanded the .zip on the desktop and dragged the original JPEG file from it to the new "Dec 14, 2008" folder.
    I opened iPhoto '09 again. Now the thumbnail (obviously the JPEG file) displays fine.
    Double checked iMovie '09... Yep, still playing the audio in ALL the clips in the event library.
    I'm not really sure why this worked the way it did. The time it took to generate the new thumbnail was ONLY for the one clip... so it seems rather odd that all the subsequent clips in the event library started to work. Perhaps I just got lucky and it is only that first clip that was throwing everything else off in the thumbnails... or maybe iMovie just looks at the first clip in the event library to determine if it is playing sound or not for all of them?
    Another oddity? The original SANY0001 file is "17.2 MB". The new one, which appears to be exactly the same in quality, is "10.8 MB". The "More Info" section reveals a bit more that might be of interest. The original is Codecs: Photo - JPEG, Integer (Big Endian). The new one is Codecs: Photo - JPEG, Integer (Little Endian). Total bit rate in the original is 2,570. In the new one it is 1,605.
    Ah well. It works!!! Now I can finally have some fun exploring the new features of iMovie '09

  • Imovie on my ipad ...refuses to recognize AVCHD Video. Also when i remove video clips already used in a project, it is unable to recognize missing clips after I've put them back. How do I get around these 2 issues?

    My iMovie refuses to recognize, import, or work with AVCHD Video. It also refuses the same video clips even after I have converted them to Mp4. Also, when I delete a video clip already used in a project, then later import the same clip back to my ipad, the software is unable to recognize and find the clip again! Help! How do I get around these issues?

    Hi Craig,
    I also got the second problem. The storyboard on iMovie trailer has all these missing videos. If I import them on my iPad it doesn't find them.
    If you find a solution it would be much appreciated to share it here ... I'll do the same.
    Thanks,

  • How do I slow down a clip, smoothly from full-speed to full-stop, then speed up again?

    I know that I can adjust the speed of a clip, but what I can't figure out how to do easily is make the clip slow down smoothly, as though time was freezing over a period of say 10-seconds, until it stops.
    My way of describing this (although I know it's easier than this) is to individually clip each frame and set each frames speed at 99%,98%,97%,96% until 0%
    I have read there is a way of doing this by automation, but wonder if someone can tell me how it is done?
    Thanks for the help, cheers, MP.

  • IMovie Clip Speed Issue! Please Help!

    Hey Guys.
    I have been having a weird issue with iMovie '09. Here are my current iMovie and computer specs.
    IMovie '09 - Version 8.0.6 (821) Latest Update
    *Running on:*
    Macbook 5,1 (Latest Updates)
    Mac OS X 10.5.8
    Processor - 2.4 GHz Intel Core 2 Duo
    Memory - 2 GB 1067 MHz DDR3
    Purchased a little over a year ago.
    *My Problem:*
    I start a new project in iMovie, I import the footage from my camera (Sony Webbie HD MHS-CM1 Camcorder - 1080p). iMovie imports the footage into 1440 x 1080 .mov files.
    When I drag a event clip into the project area. I am able to preview the project as I work on it in the top right hand corner. Next I want to speed up the clip to make it fast forward. I click on the clip in the project, it highlights yellow. I click on the gear in the bottom left hand corner of the clip and click on clip adjustments. If I adjust the speed to any speed, even if I check reverse and I click okay. I preview the project and the preview in the top right corner is frozen at the first frame of the clip. The sound plays from the clip and regular speed. The clip in the project can no longer be adjusted or even selected. All I do from there on is delete the clip, I can't do anything and I am forced to restart the project and do it all over again, which wont work. The problem is I really need to use the clip.
    I have tried to restart iMovie and even the computer, but it does nothing.
    Please help me fix this problem.
    Thanks,
    Kyle

    Right click on the clip in your Event and see if it gives you the option to Optimize Video. If so, optimize your video and it should be able to do the speed changes.

  • I imported an hour of video into iMovie HD and cut it down to a 33 sec clip, and emptied the trash.  When I save the project, the file size is 20Gb.  How can I save just the 33 sec clip?

    Non-destructive editing is an important feature of iMovie HD 6.
    iMovie preserves the entire copy of every clip you place into your movie in case you change your mind at a later stage.
    So, if you have cut out one minute from a 45 minute clip, iMovie will have stored two complete copies of that clip. This is why is helps to set import as 3-5 minute clips rather than one huge chunk. As DV runs at 13GB per hour your project files can get very big.
    One workaround is to complete the editing of a section of the movie, then export that to Quicktime: highlight the clip/s, choose Share-Quicktime, turn on Share selected clips only, and choose Full Quality from the pop-ip menu.
    Once you have saved the stand-alone clip to your hard drive, you can re-import it into your project using the File/Import command, and delete the original long clip/s from the project.
