Imported video has strange squiggly effect when there is motion

Hey everyone,
I am trying to edit and put together a video from our honeymoon. I am brand new to macs, and the whole editing business. Unfortunately I have a Samsung SC-MX10 camcorder which is dreadful as far as mac compatibility goes. According to my research, it saves video in the MPEG-4 format using the SEDG codec.
So I finally was able to get all the files onto my mac (iMovie doesn't sync with the camcorder) and they are all .avi files. I downloaded Perian and I am able to view the files with quicktime. However, getting them into iMovie was a different story.
With much more research online, I downloaded QTAmateur which is supposedly a free version of QuickTime Pro, and I have several video converting options available. Among the list, I chose to convert them to quicktime videos. When I open up these converted files in QuickTime, they work perfectly. HOWEVER, when I import them to iMovie, they suddenly have this strange "squiggly" look whenever there is motion in the video. It gets really bad, and i don't want to have this in my final product. Does anyone know why it is doing this, or how I can fix it?
If anyone can figure this out it would be AMAZING!
THANKS!

That's DV video for you - it runs at 13GB per hour. Your cam highly compresses the video to the MPEG4 format, which actually is detrimental to the quality of the video image.
Onu Marx stated that iMovie HD would give you better results. I think he meant to say iMovie HD6 and you may see some difference, as 08 uses single field processing, which eliminates every other line in a frame, whereas HD6 uses the whole frame. iMovie HD6 is a free download for owners of iLfe 08:

If you are unhappy with all this extra work you need to do to edit from the Samsung, I suggest you look for a new cam, preferably a miniDV tape cam with firewire, which will work seemlessly with all iMovie versions and give you great lossless DV right off the bat.
With reference to your question - "Is there no other format . . . NO.

  • Strange "strobe" effect when doing slow motion

    hi
    after using fcp for a year now, i strangly encountered a problem in a video i need to deliver in 2 days.
    whenever i did a 50% slow motion i get a strange "strobe" effect. when the frame is more or less static then you wont be able to see it but when the camera pans or the object in the frame moves it is very disturbing.
    this is only noticable when viewed on a tv set, not on my display.
    i thought it was in the encoding so i did the whole "export using QT" again, this time making sure its 2 pass VBR 6.8 to 8 mbps. still there.
    i am working on a Pal system without a monitor so i burned the video onto a dvd using dvdsp (as usual) and then played it in a pal dvd player and tv but this strobe thing is still there.
    b.t.w the interlace option on the "export using QT" was set as auto, the same as always.
    i didnt do anything different this time but still i get that problem. what could it be ? all the settings in fcp settings are set to 100% quality and the video is fully rendered.
    i appriciate your comments and help.
    thanx

  • I just switch from tape to digital. The video  has a little bounce when played on tv. I copyied the DVD to a folder

    I just switch from tape to digital. The video  has a little bounce when played on tv. I copyied the DVD to a folder, and burned it to a dvd.
    I can see in bounce at the bottom of the screen.

    David
    Premiere Elements 11, 12, or 13 on Windows 7, 8, or 8.1 64 bit....
    You could go back to the project and, in the Edit area, scale out the bouncing bottom edge. I am assuming that it will be visible there.
    Then do another burn to folder, and then take the saved folder's VIDEO_TS to DVD disc with your 3rd party software, presumed ImgBurn.
    If you want to scale width and height together, then leave the check mark next to Constrain Proportions in Applied Effects Tab/Applied Effects Palette/Motion Panel expanded. If you want to scale width and height separately, the remove the check mark next to Constrain Proportions in Motion Panel expanded.
    Please let us know the results. We might consider the Crop Effect also. (fx Effects/Transform/Crop with edits of it int Applied Effects Tab/Applied Effects Palette/Crop Panel expanded).
    Thank you.

  • I imported videos from photo into iMovie when I set up iMovie (obvious mistake) and now iMovie doesn't work properly, nor can I move specific videos into a folder where I want them. How do I fix this?

    I imported videos from photo into iMovie when I set up iMovie (obvious mistake) and now iMovie doesn't work properly, nor can I move specific videos into a folder where I want them. How do I fix this? I even tried deleting iMovie, bought a new copy and installed it, but the folder "iPhoto Videos" is still there and I can't get new clips loaded to iMovie, especially where I want them. Please help.

    The iPhoto Videos do occasionally have problems. I've seen a lot of people write messages to this Discussion group describing similar problems. The only thing that seems to get around this problem is to pull the video clips out of iPhoto then import them directly into iMovie. Once the troubles with iPhoto Videos starts, I haven't yet seen anyone write back with something that they did to fix it.
    The most difficult part of doing this is the movies in iPhoto might be a little difficult to track down. But you can create a smart alum that does that for you. Go to iPhoto > File Menu > New Smart Album:
    Set the first pulldown menu to keyword, second to contains, then in the last box type Movie with a capital 'M'. Then click OK. This smart album more or less does as search of the whole iPhoto Library and only displays items that match your search tearm of "Movie" exactly. In that smart album then you can find the original Movies you want to move out of iPhoto and into iMovie, <CTRL> click on the Movie clip, then choose Reveal in Finder. That will jump you out of iPhoto temporarily and into the iPhoto Library folder. From there you can move that movie file to the desktop. Move all the clips you want, once they're all collected up go to iMovie and go to the File Menu > Import Files. Then point it to the desktop where you moved your video clips.
    This will put all those videos into an Event folder in iMovie and bypass iPhoto Videos altogether.

  • When I view or upload files (such as on You Tube) there is no longer normal image movement. All action has a "strobe" effect as in slow motion, but audio seems normal. Is this a plug-in problem?

    All of a sudden when I view a file that's been downloaded, or viewed on line, whether in Windows Media, or on You Tube on line site, or Power DVD Play program, the image appears as if it was in a slow motion "strobe" effect, while the audio sounds consistent, (barring the frequent stalls). If I burn a DVD, it has the slow motion strobe effect burnt into the disc as well & is difficult to view on a DVD player. Is this a plug-in problem that has suddenly manifested, and is there a way of getting the system back to it's normal operation??
    == This happened ==
    Every time Firefox opened
    == Since about 2 weeks ago.

    Hello Joe.
    Try disabling all add-ons (that's extensions, plugins and themes, go into ''Tools > Add-ons'') except for Flash and see if the problem persists. If they don't, enable one add-on at a time until you find the problem. If they do, try a new [http://support.mozilla.com/en-US/kb/Managing+profiles Firefox profile] and see if it has the same issues. If it does (make sure other plugins aren't enabled), you need to contact Adobe for support on their Flash plugin ([https://www.mozilla.com/en-US/plugincheck/ updating] it will be the first thing they tell you to do). If it doesn't, please tell me.

  • Why am I suddenly getting a strange banding effect when printing.

    I've been using Adobe Photoshop CS5 for the last two years and I've started getting a strange banding effect on my prints.  Photoshop seems to be the only application that is effected.  I print on a large format printer, my drivers are up to date, if I print a smaller size and fit to page (test print) the print is ok.  When I print to full size I start having the problem. 

    However, when something starts acting weird suddenly, that is usually a sign to re-set your Photoshop preferences.
    Preferences files vary by name and location for each version of Photoshop.
    To re-create the preferences files for Photoshop, start the application while holding down Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac OS). Then, click Yes to the message, "Delete the Adobe Photoshop Settings file?"
    Mac OS
    Important: Apple made the user library folder hidden by default with the release of Mac OS X 10.7. If you need access to files in the hidden library folder to perform Adobe-related troubleshooting, see How to access hidden user library files.

  • Imported Video has a Greenish Tint

    I installed Premiere CS4 on a Dell Latitude  E5400 laptop and am trying to edit a video.  However, when I bring it into Premiere it has a greenish tint as does the border around it. See attachment I imported it in various formats (mov, avi, wmv) and the problem persists. Any help would be appreciated.

    Alas, the colour tint is a classic video overlay problem. Update your driver to the latest one from Dell and cross your fingers.
    It's probably not an issue with your footage or Premiere, just the way Premiere presents the Program monitor.
    In fact, if you export said video, you'll probably find there is no colour cast present.

  • Is it possible to exclude one video card from After Effects.  There are 2 in this system and one, I believe, does not have CUDA support.

    This system has 2 video cards.  A new nVidia Quadra 4000 and an older BlackMagic DeckLink Extreme 3D+. I would like After Effects to use only the nVidia card so I can take advantage of CUDA. Is there a preference I can set so that AE only uses the nVidia card?

    What version of After Effects do you have (down to the decimal points)?

  • All sounds besides ringer do not work. Video has no sounds. When i send video to someone else, they can hear sound. Iphone 4s

    All my sounds have stpped working. Only ringer sound works. When I send video file to someone, they can ear sound. I cant hear it. I have iphone 4s... please help

    Just had this occure as you described: ringer only all other sounds mute. The second time this has happened. A simple reboot (turn off and on) restored normal functionality. the first time I read some post but don't remember how I restored it then so I am back here again. Seems like the problem and fix is different for different people, but this time for me a reboot did it.

  • MacBook Air has strange new behavior when I log in.

    When I go to log onto my MacBook Air, the screen stays dark except for a strange "path" that reveals the screen behind my curser. Very strange. Having owned Macs for years, I've never seen this before. Has anybody else had this happen? What would cause this?

    Does it happen when you startup in Safe Mode ?

  • Imported video has "motion-blur" artifacts, but original is fine.

    Hi,
    I've just purchased a Samsung SMX-F30 standard-def camcorder. I've shot a few clips and decided to test its compatibility with iMovie. iMovie recognised the camcorder with no problems and imported all my clips without any hassle. However, when I play the clips in iMovie if the clip has any motion, say an arm or hand being waved or head moving, then the image blurs in a way I can only describe as "interlace staggering". That is, alternate lines in the fram shift position left and right alternately. This is really annoying as you can imagine!
    A few details about my setup other than the machine details below:
    Clips recorded in 4:3
    iMovie defaults when importing
    iMovie version is 8.0.2 (I think)
    iMovie imports to an external firewire 500GB hard drive
    Clips not analysed for stabilisation after import
    Camera records in "H.264/AVC Format" according to the manual
    Recording at approx 5Mbps
    Camera was using built-in electronic anti-shake
    I hope someone can suggest a few things to try as I've just returned to movie making after owning a Mini-DV based camcorder 10 years ago!
    Thanks
    Stuart

    His book gives specific directions and more info on AVCHD with frame rates and bits...so definately buy the book. Your question: It kinda depends on your set up. Many people need to import into imovie 9 just so they can get an editable copy of the footage. So then you make your way over to the events folder and import the events into another program for turning it into progressive and de-interlacing it. You have to becareful because you will have duplicate footage.
    He goes into details on how to do this. I have a different workflow because i import on a different machine using imovie6 since i am working with tapes. Then i convert it before i import it again into imovie. My DV footage doesn't get motion blur though so i am only doing this workflow to ensure no quality loss.

  • ICal problem. Everyday has a dot even when there's no events

    I have a dot on every single day of the iPhones calender even on days with no event. I sync with iCal on my imac at home and sync with outlook on a vista pc at work. It has been working fine for weeks , now i have a dot on every single day. Any suggestion on what can cause this?

    I had the same thing happen to me. The problem is that you have an appointment with the 'end' time that is earlier than the 'start' time. It may take a while to find it, but it's there somewhere. I actually had two of them (example of one below).
    Start: November 27, 2007
    End: November 26, 2007 (one day earlier)
    Once I changed the end time to be the same (or later) than the start time, all the dots went away. Like I say...I had two different appointmentss like this that I had to find.
    Hope this helps!

  • How to import video files from external hard drive?

    Premiere Elements 12 Mac
    A few more questions for now.
    Taking your particular .avi files out of the equation, can you import any other format from Add Media/Files and Folders pointed to this external hard drive? What is the format of the external hard drive? NTFS or FAT32?
    It is my recollection that AVCHD.avi has always been reported as highly problematic. Yet you seem to be saying that you have no problem importing them in to the project from the desktop with the program's Add Media/Files and Folders/Project Assets to Expert workspace Timeline.
    Did you purchase your Premiere Elements 12 from the Mac App Store or from Adobe? If Mac Store, what do you have Adobe Premiere Elements Editor or Adobe Premiere Elements Quick Editor or some variation thereof?
    You wrote
    A number of users are experiencing this issue - they connect their hard drive, load Elements, start a new project and go to add media (from the ext hard drive) using the files and folders option.
    Could you supply more information on this via link(s) which have reported this issue.
    Thanks.

  • Video compression in After Effects

    Hi,
    i have a little problem with video compression in After Effects.When I was looking for example on that video: http://vimeo.com/18672227 the quality in HD is really great. When we was trying to compress our video in After Effects, the best result, which we was able to get, had 80 MB and 18 seconds and the quality was still much worst than like the one which i posted above. 80 MB for only 18 secs of video and with that quality seems too much for me. I really doubt it is normal. Then for example video which i posted above should have 2000 MB and i really don't believe that.
    Is there some way how to get HD quality video for internet streaming with affordable size from After Effect rendering compression? Which settings, formats or codecs I should use? Or do i need some other Adobe program which is builded for this better compressions?

    You are looking for an easy answer where there is none. Yes, there are better tools than AE for final compression like Adobe Media Encoder, but your format will still be H.264. The rest is very much a matter of experience and a combination of settings for data rates, encoding passes and so on plus tricks on how to deal with Gamma shifts and color skewing due to the chroma undersampling. Without seeing the actual footage, nobody will be able to give you any exact pointers, but generally the presets you find in AE and AME will provide a good basis. The rest is just tippy-toeing through the settings and learning by doing. Also do some general research on the matter. Because it is so complex and difficult, this topic is discussed to death on pretty much every forum that deals with video editing, DVD/ BluRay authoring and ripping movies for fun...
