IMovie Quality Playback

I have made several iMovies and the quality is terrible. My pictures are 5 Megapixel or 2580 x 1950 when I drag them to the time line and play back full screen on my 20 inch Mac Cinema Display; all the curved or diagonal edges of people and objects are saw toothed. I have my monitor set at its highest resolution 1680 x 1050 resolution. The pictures are worse than those I view on the internet. They seem to be enlarged 72 ppi photos.
We have a group that meets each month to show travel slide shows. Most presenters use their camera slide show software to show their slides and they are superior to iMovie. I chose iMovie because I could insert video clips to play in sequence with the related slides. When I burn them to iDVD they look the same as they did in iMovie. This works great except for the Jagged or saw tooth edges. Most other presenters use Windows laptops and their shows are of better quality and they can add picture info at the bottom margin of the picture. I might try Keynote but when I open PowerPoint presentations in keynote I lose the sound and I have not found a way to import a folder of sides.
iPhoto slide shows keep picture quality and look great on screen but it will not play QuickTime movies
when I add a movie the show will not play it will import it in sequence be the slide show will not startup.
Any ideas other than camera software or iPhoto to create a reasonable quality slide show without spending a fortune on professional software.
Any suggestions would be appreciated

Hi
Did Your movie look OK when it was edited PRIOR You tried to do the DVD ?
My main guess is that You used "Share/Export to iDVD" from within iMovie and
probably not used Ken Burns project.
If so - then Your movie will look bad too. If You open iMovie and try to play it.
There is a problem with photos in iMovie due to how (bad) iMovie renders.
I do (or rather don't)
• I don't use Ken Burns Effect at all on any photos
• I DON'T use "Export/Share to iDVD" function in iMovie
I do
• Import my photos and edit them with my music and voice-over
• CLOSE iMovie (Don't try Share to iDVD - though it will harm the project)
• OPEN iDVD and either import the movie project (or just drop it into) iDVD
Now iDVD will do the rendering and so much better.
Alt. is to in iMovie use Ken Burns effect (on all photos - I think/guess)
• This is a way I don't have adopted - at all.
IF You have Used Share/Export to iDVD - Then
• You'll have to RE-Import the photos to Your iMovie project
• Re-edit them into Your SlideShow. The old ones is harmed and have to be exchanged.
• Now try again.
The amount of material is NOT the problem - my kill of Vacation movie made in iMovie
was >> 5 hour movie and >> 500 photos to a duration of more than 6h 20min
No not to DVD - but out to a VHS-tape in LP-mode.
The only thing of importance when dealing with Mammoth-projects are
• free space on internal boot hard disk >> 25Gb recommended
• space for material and movie on any FireWire Mac OS Extended formatted hard disk
eg my >>6hour project needed >> 200Gb free space + 25Gb
This was 4x3 standard TV-video (miniDV tape)
IF 1920x1080 HD then You'll need to multiply with about 5 at least.

  • Video quality playback choice

    I don't know if this idea has already been suggested, but it is actually 5 years overdue. So here it goes.
    Is it possible in the next update for Apple to offer a video playback option of SD(240p or 360p), HQ(480p, or 720p), or HD(1080p) on the Iphone screen, of cource depending upon what the maximum allowment of the screen playback is. How I mean by this is that no matter if you are on wifi, 3g-4g(AT&T), or LTE, you have a choice of video quality playback options sitting somewhere on the screen; especially youtube, I would like the option to playback video in standard quality, high quality, or hi defination (pending upon phone hardware).
    Thank you very much.

    Thank you Russ for your reply.  I have actually run this both ways, one time as a project and the other time out of the timeline.  Each time the video goes widescreen and the quality is less than if I run it in Quicktime and Imovie.  I have wracked my brain trying to figure this out. Tom was stumped too why 640X480 would go wide.  I haven't see that before.  Should be a 4:3.  Any help on this would be greatly appreciated.  Let me also clarify something.  These clips I have been working with were not shot by me.  I am producing a Documentary on the flood that ravaged our Colorado town in September.  Since I just purchased 10.1, I haven't loaded up the video I took of the flood.  It had been at the TV station, and I just retrieved it tonight.  I am going to import it tonight to see how Final Cut handles it.  Hundreds of folks have sent me vid and stills so I don't know what type of cameras most of the vid came from.  Once I import my video, I'll know if this is a Final Cut issue or something to do with the clips that were sent to me.  I am not a newby at editing, having worked with previous versions of Final Cut, Adobe Premier and a Video Server at TV stations.  I should be able to figure why the clips from others are not being handled correctly by FC, but I haven't resolved that yet.  Hoping other professionals had seen this and would know the answer.  I will be up for hours working on this.  Even if my video works fine, I still need to find an answer as to why the other clips are not playing back correctly.
    All the best,

  • IMovie Erratic Playback

    I have composed a 5 minute program (1.15GB) and a 35 minute program (12.95GB) in iMovies. Both programs have audio tracks for narration and music. The 5 minute program plays perfectly and exports to tape. The 35 minute program plays erratically, often freezes video, the playhead stops then jumps ahead many seconds, and the playhead keeps jumping ahead for 10 to 20 seconds after commanding stop. Needless to say, editing becomes a nightmare. The 35 minute program does not export to tape because video freezes and then goes to black.
    However, exporting both programs to iDVD, creating a disk image, and then burning a DVD disk works perfectly. Playing the DVD disk on a HD television gives smooth video and audio.
    Is the erratic playback during editing and export to tape due to iMovie software or due to my Mac G4 hardware (933 MHz, 1 GB SDRAM, 133MHz Bus)? Would Final Cut Express avoid this problem, or is my G4 too slow?

    In addition to Mike Bisom1's good comments:
    The stuttering problem that you describe is fairly common. It frequently is caused by the number of separate (not embedded in the video) audio clips that you have in your project, or by overlapping audio clips. This varies from computer to computer. Fortunately, as you have observed, it does not carry over into the final burned DVD. This problem is usually project specific, again as you have observed, and may appear only in some, but not all projects.
    You can try is going to iMovie/Preferences/Playback and select Standard for smoother playback. This doesn't usually help much, however. Or, you can export all or sections of your iMovie project, that you have edited, to your desktop as a Full Quality Quicktime movie, and then drag that movie back into your project as one large clip with no separate audio to replace the clips that were there before. That usually solves the problem. Toggling back and forth from full screen display to smaller screen display during playback often helps to unfreeze the video.
    Other causes for jerky playback, such as conflicting plug-ins, are discussed in this thread:
    http://discussions.apple.com/thread.jspa?threadID=1662473&tstart=0
    Some users have reported jerkiness on playback after upgrading to Quicktime 7.5. If you have recently upgraded to 7.5 you may want to read the following thread:
    http://discussions.apple.com/thread.jspa?threadID=1649832&tstart=0
    As a final comment, it sometimes helps from a work flow standpoint to create and edit your iMovie project in separate sections using separate iMovie projects. Then you can export these separate projects to your desktop as a Full Quality Quicktime movie and then drag them into your central iMovie project as larger clips. That often will avoid the stuttering problem, because your audio will be embedded in the larger video clip rather than in separate audio clips.

  • The control of quality playback in preferences has changed.

    The quality playback option in FCP X v10.2 preferences has changed. How do you control the quality of the audio and video playback now?

    A knob? I don't see no knob. Just a dropdown called "view." I'd rather have a knob. How do I get a knob?

  • Quality Playback-.need a little help

    Quality Playback….need a little help
    I’ve posted in the Premiere forums too, because I’m not sure where my issue is in converting .MOD files, the export of edited footage from Preimere Pro CS4 or if it’s in Encore.
    The quality just does not seem that good, I know it’s not HD quality, but it should be better than what I have.  Seems over pixilated especially around objects.
    Here’s my steps
    Convert .MOD files using Mpeg Streamclip to a .DV file format
    Settings Compression DV (DV25)
    Standard NTSC 720 x 480 29.97 fps
    Aspect 16:0
    Everything else is default
    Import to Premiere Pro CS5
    Edit footage
    Export to quicktime .mov file
    NTSC DV Widescreen
    720 x 480 quality 100%
    codec is DV25 NTSC
    Import .mov files to Encore CS5
    Build menus and playlists
    Export with default settings approximately 1hr 45min of edited video
    Thanks

    Bill
    Thanks for your help and patience.
    I posted a screen shot of the mov export settings I was using.  I’m going to try Ann’s conversion method on the mod files to see if that improves things.
    You asked about the Encore transcoding, what do you mean by that, are there other settings in Encore that I need to set?
    I have an 1hour 45 min of video in my Encore project, burning to a 4.7 DVD.  Encore says it’s using 3.3bg, which seems low.

  • IMovies Quality problems..

    Hi All.. Looking for some help -
    Started to use iMovie to create a slideshow of pics and the various effects available but seem to be having some quality issues when i play back...
    when I'm chosing the titles (this is imovie '06) the examples look all crisp and of high quality, the same when I first import a picture. BUT
    If i then try and run the slideshow in either the demo box on screen or by making it full screen the quality is rubbish! Straight lines on pictures are all jagged and look bad quality - not at all like the original images, and the beginning title words look rubbish, not at all crisp like they were when I picked that style etc. If I change the colour of the words then on playback there is a white halo round the colour. Basically it looks really bad and poor quality
    What am I missing? The fact they come up crisp and nice to begin with then goes crap when i play back is vexing me.. I have the macbook with 2.16 processor. I have tried changing the quality in preferences up and down but no luck.
    Sorry for the long message and if this is a stupid question but I can't find the info in the help section.
    I had posted this in the iMovie help forum but it seems very quiet in there..
    Thank you for any help!
    Sam

    Try exporting and seeing how it looks.
    I'm no expert in iMovie, as I usually use FCP, but it seems like iMovie doesn't show full quality on it's playback window. Try an export, it may help diagnose the problem.

  • Bad quality playback when burnt to DVD

    Hey,
    I have burnt my imovie project using the share - media browser in imovie and then the professional setting in idvd. When I play it on my new sony dvd/bluray player on my full hd tv with HDMI lead it has very poor playback. The sound is very muffled and the picture is slighty jumpy.
    However when I played the dvd in my parents old dvd player still running off a scart lead but again an hd tv it was perfectly fine with great sound. Can anyone explain why this is and how I might achive a good picture and sound quality in my dvd/bluray player?
    Thanks!

    Hi
    I think there is one more thing to this.
    • Your parents DVD-player most probably has a superior picture correcting chip in it
    BUT
    iMovie'08 or 09 or 11 - are not the tool to use when wanting a DVD in as good quality
    as DVD can be (SD-video as old TVs)
    Due to that they discard every second line resulting in a less sharp picture.
    I use
    • iMovie HD6 - or - (But do not use "Share/Export to iDVD" - only directly import into iDVD
    from within iDVD ! )
    • FinalCut (any version) - or -
    • FotoMagico™
    They all delivers maximum to iDVD
    Other thing I do
    • Secure a minimum of 25Gb free space on Start-up (Mac OS) hard disk
    • Use good DVDs - I use Verbatim
    • DVD-R
    • Burn speed set down to x4 or x1
    • Pro Quality encoding

  • Does the quality playback matter when I import footage to edit in a project

    I don't have an HD cam, but I have a professional camera, a Canon GL2 to be exact, and I was just dumbfounded when I was importing the video into my project and it was being viewed blurry! I then adjusted the playback quality to highest with field blending and it improved. My question is, will I lose the quality of my footage if I change the playback on the program? Another side question is, although my cam captures in 540 resolution, for 480p, will I always get the maximum quality set in my footage with iMovie HD?

    AxelKid wrote:
    .... will I lose the quality of my footage if I change the playback on the program? ...
    the setting of the playback quality has no effect on the final project.. it is 'Preview quality' ..
    and: when you export your project 'QT/FullQuality' and watch it with QTplayer, you'll notice again a (dramatic) loss in quality.. that, again, is a Player's fault: the file contains full quality, but the Player has to be set to 'high' ....
    .... although my cam captures in 540 resolution, for 480p, will I always get the maximum quality set in my footage with iMovie HD?
    iMHD is meant for TV delivery, so it offers 'just' the qualities, you choose under 'new project' ... (and, for sure, importing SD content into a hiDef project doesn't 'improve' the quality )

  • Bad quality playback

    After I transfer my video clips to idvd, the quality on playback is very poor when play it back on dvd. I seem to lose quality from my dv cam to dvd after transfering to imovie. Any tips??

    Do you mean when you play it back in iDVD, or using DVD Player?
    Either way, what you see on your computer screen is not as good as it will appear on a TV.

  • IMovie quality degraded from input quality

    Hey out there,
    Can anyone help me? I have great quality video that's been input into iMovie, but when I am playing back in the application, it looks grainy, pixelated, and just gross. Even the title pages look good when I make them, when I play them back they're crap.
    Help?

    What are the playback settings in iMovie Preferences? I don't have the older version anymore but I recall it has similar settings for playback that the newer versions have. You can set it for smooth playback which corresponds to a lower quality image. Highest quality settings can cause jumpy playback if your computer is not so fast but the images look better.
    Another thing to keep in mind is DV video generally looks worse on a computer monitor as compared to a TV. Its especially noticable with titling because when you create the titles they look high resolution but after iMovie renders them to the DV format, the resolution is reduced. This is perfectly normal. You'll find that if you export the video back to the camcorder or DVD, the quality will appear much better when played connected to a TV.

  • IPhoto to iMovie juddery playback

    Latest vers of iLife.
    Created a Ken burns slideshow in iPhoto, export out with 1080p settings. Then import in to iMovie. The playback is unusable on the pans, really juddery.
    Is this a frame rate issue? How do I check? Really getting frustrated with it as its a project I need to get finished and on to disk for a wedding client, I really dont want to have to go back to making a simplified version on Windoze but looks like I might have to. PLEASE HELP!!!

    Given that iPhoto can export it intact, this sounds more of an iMovie question, really. If, for instance, it's DVD quality video then iMovie may not open it without translation to another format. Best to post over here:

  • IMovie Quality

    What would be the best export settings for an iMovie movie for use in DVD-SP? I am looking at around 20 movies ranging from 3-10min each. I recently switched from CD based distribution to DVD and would obviously like to utilize the DVD's capacity but would just like to know a ballpark figure for size/other settings from within iMovie.

    You may be better off just compressing it into an MPEG-2 from iMovie and avoid the intermediate step and recompression/export.
    Not sure which version you have of iMovie, but go to Share.
    Then select expert and the dialog will pop up for Save File As...
    On the bottom select Export: MPEG2, then you can try one of the default settings (use 2 Pass selection) to see if that works for you, very often that can provide decent results
    If not decent results, click on Option and In the quality Tab set it for 2 Pass and use a higher minimum rate and max rate (note some footage may look better with one pass)
    then aPac/Dolby the resulting AIF file from the MPEG2 export.
    Note that the lower the rate you use for the MPEG2, the less chance of having playback issues occur when burning DVDs from your computer when played on DVD players. There is usually not a remarkable jump in encoding quality based on the source footage from let's say 5 to 6. (In fact bitVice, a 3rd party encoder, defaults to 4.5 because that seems to be the settings where quality and size of the final MPEG2 seems to work the best.)
    Definately run a test or two though

  • Problem with iTunes and low quality playback on headphones

    So I have an awesome pair of Phillips headphones that are awesome and recently i've been using my headphones and noticed that during playback the audio quality was not what it used to be. Crackily on the high notes and fuzzy on the bass notes plus overall just bad quality. I investigated more and isolated the problem to itunes and not my headphones. They work perfectly on an ipod or when I play a video on youtube. So I am wondering what is wrong. I assume it as something to do with iTunes. Any suggestions would be greatly appreciated. Thanks
    -Winfield

    I did try adjust the sound enhancer originally (should have noted that). It helped with some of the notes, did not fix. Where is the equalizer in 10.6?

  • How to keep the original imovie quality as much as possible?

    I've completed an iMovie project which lasts a few minutes short of one hour. The size of the iMovie project is 12Gig.
    I want to burn this to a dual layered DVD using iDVD, and at the same time maintain as little compression as possible, keeping the quality has high as possible.
    What is the best way to do this? Because when I export the iMovie file to iDVD using the create iDVD Project, and set my iDVD prefs to "Best Quality", and my "Media Type" to 8Gig (Double Layer) I end up with an iDVD project file of 3.39Gig.
    How is it possible to create a DVD from the 12Gig iMovie file which, when compressed, will be larger than 3Gig, so as to use most of the disk space on an 8Gig disk.
    It seems that the only two encoded settings I can alter are for "Best Quality" and "Best Performance". I was hoping to get at least 6-7Gig, thereby only compressing the original movie by half, instead it's compressed it down to a quarter of the original size. Judging the original movie against the DVD version on a TV screen reveals a noticeable amount of quality loss. Is there anything that I can do to force iDVD to not compress the file this much??

    Sorry, the video content must be compressed to a certain level to be playable in DVD players - it's a matter of the bit-rate that DVD players can handle.
    iDVD's 'Best Performance' produces a disk with about as high a bit-rate that players can handle. Because MPG-2 compression works on frame to frame differences, to maximize your DVD quality do things like place your camera on a tripod and make sure there is plenty of light.

  • How to I burn an imovie for playback on DVD?

    I'm brand new to MacBook and imovie. I created a movie burned it a DVD, but it won't play on my DVD player. What is the correct process for burning an imovie project for playback on DVD player?

    If you like to make DVDs, give iMovie 06 a try.
    I use both iMovie 08 and iMovie 06, if I want to make a DVD I prefer iMovie 06. iMovie 08 is not as DVD friendly as iMovie 06.
    iMovie 08 has replaced "Share to iDVD" with "Share to media browser". Also iMovie 08 cannot set chapter markers, this has to be done with another program.
    When using iMovie 06, one mouse click will set a chapter marker EXACTLY where you specify. In just a few seconds set all your chapter markers. When you are done editing just "share to iDVD 08" and all of your chapter markers will be there!
    iMovie 06 and iDVD 08 is a terrific combination.
    Apple includes iMovie 06 as a free download to iLife 08 owners. (THEY WANT YOU TO HAVE IT!)
