Jerky Playback & asset replacement issue

Hi,
Just downloaded the trial version in order to see if it corrects some things I needed on 1.5
So appart from the better responce and added features wich are great I have 2 problems (so far!).
Problem No1 is that the playback of the mpeg (*.m2v) file on the timeline and DVD Preview is very jerky and unstable. I used the same assets in 1.5 and playback is fine there.
Problem No2 and major for me is that when I replace assets in a previously created project the asset length doesn't adjust automaticaly. That is not a problem if the asset beeing replaced was longer since I can drag the end of the replacement asset on the timeline, and it snaps to the right length. But when the asset beeing replaced is shorter than the new asset there is no way I can drag the end of it to he new duration. Only way is to delete the m2v from the timeline and re-enter it, but that deletes all chapters and links to allready created menus with it. Is there anything I can do about that? I use asset replacement every day and this is a major drawback for me. I will have to stick to 1.5 for the time beeing...
Anyhow thanks for a great piece of software wich I was much expecting and sure to buy soon.
Cheers
Christos

For the asset replacement options that are not working as you expect, try this:
PROBLEM:
When replacing an asset in a timeline that is longer than the original, it is not always possible to extend the duration of the new clip by dragging it.
METHOD:
1. Create a new project.
2. Import an .m2v file and it's corresponding .wav file.
3. Make a timeline with these assets.
4. Click the .m2v or .wav asset in the project window, press Ctrl-H, and replace it with an .m2v file that is LONGER than the original. After importing notice in the timeline that the new length is the same as the old one.
5. Drag the tail of the replaced clip to extend its duration.
RESULT:
When you drag the tail of the .m2v or .wav file to extend the duration, the clip 'flickers." If you release the mouse when the clip "flickers" off or when the mouse is beyond the maximum duration of the clip, it reverts to the original duration. The same behaviour is exhibited when trimming the clip.
Note: Although .avi files exhibit similar flickering, you can extend or trim the clips without issue.
EXPECTED:
The duration of the clip should always be extended or trimmed to the point where the mouse is when the button is released. If the mouse is beyond the maximum duration of the clip, the duration should be extended to its maximum (like PPro).
WORKAROUND:
1. Position the CTI at the desired out point.
2. Drag the tail of the .m2v or .wav file as close to the CTI as possible while it still "flickers" on.
3. Zoom in on the tail of the clip and repeat step 2 until the clip reaches the desired duration.

  • Jitter, stutter, or jerky playback on output

    Hi friends,
    I've edited a video in Premiere Pro CS4 and it plays smoothly in the timeline. However, when I export it for DVD output, and then preview it in Encore, every minute or so, it will play one frame out of order. I don't know whether to describe this as a jitter, a stutter, or jerky playback. The preview is accurate: if I burn a DVD from Encore, the DVD will have the same glitches in playback. Again, Premiere plays everything fine.
    The frame can be pulled from before or after the current point in the timeline. The first glitch occurs at 08s 15f and plays frames in the clip in this order: 1,2,3,4,17,6,7,8,9... Then it goes to 01:24:15 and partway into another clip does this:
    24s:14f
    24:15
    24:00
    24:01
    24:16
    25:02
    24:17 (back to normal)
    Both of these clips with these symptoms have a lot of movement (people moving independently in the frame, plus camera movement), but there are other clips with nearly as much movement, and they do not have a problem.
    The source footage is AVCHD 720 30p in a matching timeline. I do have some SD footage later in this timeline. This SD footage was captured to the computer via Firewire from a Canon Optura. It is "Scaled to Frame Size" and rendered in the timeline, and is causing zero problems. I exported using the Media Encoder. I am outputting to DVD using the MPEG2-DVD and NTSC Widescreen preset, with the aspect ratio changed from 16:9 to 4:3 and the quality set to 4.5.
    I'm running Premiere Pro version 4.2.1 and Encore 4.0 on an Intel Core 2 Duo T9550 2.66 GHz with Windows 7 (64 bit), 4 GB RAM, a 5400 RPM 320 GB hard drive running the OS and the video files located on a USB 2.0 7200 RPM hard drive.
    If any of you have ideas, I would be grateful.
    Thanks,
    Russ

    I've been having this problem since installing Snow Leopard with QuickTime 10 way back when and it's caused me real problems with video rendering. I think it's a codec issue as my raw video files play back ok (H.264 codec), but when I export them and save as Photo jpeg or motion jpeg etc the playback has about 4 or 5 seconds of jerky playback near the beginning of the file.
    I've just tried opening all my test files with QuickTime v7 and was staggered to see them all run perfectly. It is indeed very annoying.

  • Jerky playback in Bridge CS4

    I get jerky playback of Hi Def mov files shot on my Canon 7D when playing them back through Bridge. The same movies play smoothly with no stuttering whatever on the same machine through Nero or any other player I have installed. According to my camera manual, the frame rate of these movies is 25 fps (I am in the UK using the PAL TV system) and so I set Bridge to play back at this rate (it was originally set to something like 29.77) but that made no difference. Is Bridge using a different codec or what?

    Bridge uses Quicktime, so any performance issues wil lhave to be attributed to that, most likely.

  • Jerky playback in elements organizer

    Hoping some one can help out here.  I've downloaded the trial version of Premiere elements to edit videos captured with a Kodak playsport.  When I view the captured video in the organizer, it a very jerky playback.  When I play back using Windows media player or quicktime, it's nice and smooth.
    I've tried capturing the MOV files in 720p and 720p (60fps) and have the same issue. 
    Anyone have any suggestions?

    Jerky playback in PE is almost always because you have not rendered the area where the jerk is. - or else you dont have a fast enough computer or enough RAM or have everything on one computer hard disk.
    If you have a horizontal red line above any of your video in the time ine it means you dont have it rendered. It is caused every time you insert a transition or effect or if your original meaterial doesnt match the original project settings when you imported the video.
    You dont have to render the whole project if there are only parts with a red line - just adjust the work space pointers to cover the red line and render that.
    There are numerous posts in this forum about it and the way to cure it

  • Jerky Playback of iTunes purchased TV Shows (specifically:  HEROES)

    Not yet another jerky/playback thread?
    Well, I feel compelled to do so since I have reviewed all of the jerky/playback threads that I could find and I have tried most, if not all, of the suggestions. Namely:
    1. This thread: http://docs.info.apple.com/article.html?artnum=303706
    2. Uninstalled Quicktime and reinstalled (ver. 7.1.6)
    3. Setting "waveout" for audio.
    4. Tried several bit settings for audio (16, 24) along with sampling rates (44000, 48000).
    5. Tried two different versions of NVidia Forceware (ver 97.46, ver 158.18)
    6. Two different sets of drivers for SATA
    The thing that gets me is, I've been watching HEROES all season without incident. In fact, I preferred purchasing each episode and watching it in iTunes as opposed to watching the episodes in my BeyondTV DVR (computer based). One has to conclude that SOMETHING on the system has shifted to affect this change (within the last week), although I'm out of ideas beyond the 6 listed above. I'm tempted to boot into my XP partition to see if everything is fine over there but that would mean I would have to go through the as-of-yet-unfamiliar-to-me process of deauthorizing this "computer" and hoping that my purchases shows re-download. I did this once and I lost the first 6 episodes of Heroes and even "redownloading purchased" media did not bring them back. That's a separate issue that I need to contact Apple about.
    So...any ideas? Any information that I'm lacking here to help troubleshoot?

    Update:
    I booted over into Windows XP (SP2) and everything is fine over there. So, that leads me to the strong inclination that there is something up with the configuration on this side of the divide (Windows Vista 32-bit).
    I'm now beginning to suspect some recent tweaks that were made via the nTune application. For those that don't know, nTune is a utility that allows tweaking of nVidia hardware (nForce, n4 - mobo, PCI bus, SATA, video, etc.) What I'm currently trying to research is getting the automatic tweaks that I enabled to rollback to their default settings. So far, I haven't figured out how to do this. There is an option to load a "baseline" profile from within nTune's menu however the behaviors that I noticed post-tweak are still there (difficult to explain but there are indicators that the new settings are still in effect).
    I'll post back here if I am successful in rolling back the nTune tweaks and see if that makes any difference with the video playback problems I am experiencing.

  • CPU spikes & jerky playback of audio or video content

    I've been having a problem with the flash plugin this year.  I'm not sure when it started exactly, but I'm certain that this wasn't happening during 2011.
    When at a site that uses Flash for video+audio (Youtube and similar) or even audio-only playback (Turntable, Pandora, etc), I find that the flash plugin causes spikes of 100% CPU usage (on one core) and that the video or audio will pause for a moment during those spikes.  The disruption is typically in the 100-500ms range.
    Frequency of the spikes seems to vary over time.  It's fairly typical to experience a situation where it starts off bad and the frequency of disruption lessens over the course of 30 minutes until there are no disruptions at all.  If you keep using playback, it'll work its way into being bad again.  You're likely to start using the flash plugin at any point on that sine wave of disruption intensity.  It might start working well but slowly get worse, it might start bad and slowly get better, it might start at a tolerable level and work its way worse or better depending on if you're on the rising or falling side of the cycle.
    Whatever it is, it isn't my Windows install.  I switched from an AMD FX-8120 to an Intel 3930K about a month ago and this problem persisted through new hardware and a fresh install of Windows using the latest device drivers for everything.  I've even tested different browsers in case it was an issue with only the non-IE plugin or with my specific browser (Opera).  The issue happens in Chrome, IE9, Opera, and FF on my system.  I've also tested both with and without hardware acceleration, but there is no difference.
    I have to wonder if there are any known issues with particular sound cards (Xonar STX), unusual video configurations (dual Radeon 6970s in crossfire), or peripherals.  Perhaps with output sampling rates (96 KHz) or security software like MSE?
    Anyhow, I mention this here in the hope of either raising awareness of a problem or finding answers if this is a known issue.  It's silly that playing back audio would be a challenge in 2012 with good equipment.  There is sure to be a logical explanation that can help lead me to a resolution.  Thank you.

    Hey Tbird, I was asking the guys about this jerky playback bug here:
    https://bugbase.adobe.com/index.cfm?event=bug&id=3155813
    It turns out this problem is very likely found in mainly computers with single-core CPUs or low-power mutiple-core CPUs. What type of CPU model is on your computer?
    My advice to everyone who has this jerky or choppy or stuttering playback on Flash Player 11.2 is to downgrade back to Flash Player 11.1 for now until the Adobe guys can fix this problem which seems to be with the multi-threaded decoding engine introduced in Flash Player 11.1. Make sure you uninstall Flash Player 11.2 completely before installing Flash Player 11.1.
    You can get Flash Player 11.1 in this zip file archive from the link below. Just make sure you look for the right setup folder with the right setup program file in zip file archive  (For example, if you got Windows 64-bit OS, then look for win64 (or x64 for windows ). If you got windows 32-bit OS, then look for win32 (or x86 for windows)

  • Jerky Playback Solution

    For all that have been experiencing the "jerky movie playback" or the "freeze frame syndrome" I offer this solution. I feel very confident with it as I experienced similar slow downs with my old Power Mac 8500 years ago and it was the exact same issue. At that point I had just upgraded to the most current version of Quicktime. It created a slowdown with just about every process one could think of, right down to the redraw rate on my screen (excruciatingly slow). I eventually solved the problem by downgrading back to the previous version of QT..
    In any case after recently upgrading my Imac to QT 7.0x (7.03 to be exact) from 6.5.2 I began to experience the dreaded "jerky playback" to movies that had previously run very smoothly; all movies, all sizes, and with all varieties of audio clips, music and voiceovers. It was such extreme degradation that it rendered IMovie virtually unusable. From my previous experience I immediately suspected the QT upgrade. After researching everyone's discussion threads for a couple of hours I was convinced that QT 7.0x was indeed the problem and I immediately downgraded to 6.5.2, .... and voila; my movie projects returned to their old reliable selves. (and that's with a mere 5gb free space on my hard drive). So if you're experiencing "jerky playback" I strongly suggest a QT downgrade to 6.5.2. You can find the downgrade options on the Quicktime discussion board. Hope this helps you as it did me. Happy movie making.

    Too bad you were so in a hurry downgrading, you didn't even perform some troubleshooting. QT 7 does have advantages, mainly H.264 support.
    I quote Karl Petersen:
    ”Some people have reported smoother playback after resetting QuickTime preferences. (Yes QuickTime, not iMovie.) To do that quit iMovie, open System Preferences and click on the QuickTime icon. Change something (anything). Close System Preferences. Re-launch iMovie HD.”
    I quote Steve Summers1:
    ”I found out that since I had done an upgrade install of Tiger, I still had old versions of QuickTime components in my /Users/~/Library/QuickTime/ folder. These had the same names as the new QuickTime 7 components which were in the /System/Library/QuickTime/ folder. QuickTime was trying to load the old components from my user library into the new QuickTime application.
    ”I deleted the old ones from the user location, along with some of the really old (circa 2002) non-competing components which were still in there. Then I restarted, just for good measure.
    ”My error messages went away, and QuickTime 7 is working as it should.”

  • Jerky playback, sluggish operations while editing

    I've never had any troubles with video until now. I'm getting jerky playback on my machine, where under the previous iMovie I didn't. The playback display will freeze and skip, while the vertical red place marker pauses and jumps forward. The video doesn't have sound at this point, so I don't know if sound is skipping. I'm running on a 30" Cinema display with iMovie filling the screen.
    When I take actions, such as clicking on a clip, there's a slight pause before the action happens. Scrolling through video to find the right frame to split on is very sluggish.
    The type of video that I'm editing are screen movies created using Snapz Pro X (http://www.ambrosiasw.com/utilities/snapzprox/) at 30fps, saved as MP4's highest quality. Yes, it's a lot more space, but I like to preserve as much quality as possible through the editing process.
    Activity Monitor shows that I have 266MB of RAM free, so I don't believe I'm running into swapping problems. At the suggestion of an Apple Store employee, I had an authorized Apple repair place upgrade the hard drive (to 7200RPM; weeee!) a year ago since they don't do after-market upgrades.
    I've used iDefrag to defrag the filesystem. I'm maxed out on RAM (2GB; first generation MBP).
    What types of things should I be looking for to get smooth playback while editing?

    I doubt if any card works well with CS5.
    It's best to have an Adobe PC without any video signal card.
    1. Use a capture/playout PC to capture and view the images, preferably also without using any Adobe software.
    2. Then do your stuff on the Adobe PC.
    3. Transfer the mixdown of the video to your capture/playout PC, check the field order and print to tape (without Adobe) or deliver the file.
    For now, Matrox MXO2 is also unusable with CS5. Boris FX makes things even worse.
    My PC is extremely powerfull, so that can't be it, but it's very unstable.
    Manufacturers of cards and Adobe don't work hard enough to combine their products and they just blame eachother.
    It used to be quite nice semi-pro stuff for editing but forget that with any video hardware for the time being; it dropped to amateur level.
    I'm done trying to fix it or waiting for solutions; I just issue warnings for other users and buyers now.

  • Apple tv gen 1 and 2 jerky playback.

    I have had this issue since i first purchased atv1 when they first came out....jerky playback/lag/ slight delay..whatever you call it..i upgraded my modem to an N series..i got apple extreme and ditched the belkin..i bought apple express......extended the range......
    i bought atv2 thinking maybe it will fix the problem....nope.I have all Apple hardware except the modem and download via wifi..(i have tried ethernet direct and sill the same)...i hassled my ISP and now have around 6mbps.....still have the lag.....i recently downloaded from foxtel..(ethernet) to compare and playback is perfect...what;s the go with Atv....? i am far too gone now to just leave this and accept it as normal...i still have atv 1 on a separate tv and still the same old lag.....any help or suggestions would be most welcome before i ask apple for full refunds of all the movies/tv shows i have bought..i would rather use Apple to buy tv shows and movies than Foxtel in priciple...but i am running out of ideas......when i first went to support originally Apple hadn;t heard of this....?

    Same with 3rd Gen too.  I made a movie in Final Cut Pro, exported as SD, 720p and 1080p.  Plays back smooth on Mac, iPad, iPhone etc... but on AppleTV 3rd gen, it's dropping about half the frames.

  • FLV jerky playback

    I have updated this post with more detailed information to hopefully get some help.
    I have read multiple posts/threads on “jerky playback in flash”, but nothing posted seems to help my situation.  I have tried in the Flash and PP forums, but to date no responses.
    6 different videos – all Encoded with AME and produce the same results all using the Adobe F4V (h.264 Flash) presets from PP.
    Started with the F4V/Web presets (same as source at 29.97), and then adjusted the output size to reduce Mbps until I got something to work.  Tried all settings from about 1.5Mbps down to about 0.4 Mbps, but all showed the same result.
    All AME encodes show “jerky” playback in flash/IE, but smooth in FireFox.  Audio is OK
    The video plays smoothly for a second, then shudders for about 3 frames, then smooth, then shudders, etc.
    Local playback on AMP looks fine, this bypasses the browser completely, so not really a valid test.  I have attached a MediaInfo for a sample encode below.  The HTTP code for playback is generated by DW and very simple, so I doubt it is that.
    Same behavior on 2 different systems (Win7 x64).  Systems have latest updates, etc, etc. Hardware and systems are high-end and well-tuned.  CPU never exceeds 5% and memory never above 10%.
    Have used a variety of export presets in the 0.4 to 1.5 Mbps – all with same results.  So my test set exceeds 20 exports – all with identical behavior.
    Tried VBR 1pass and CBR.
    Same behavior on 2 separate hosted ISPs and local playback. All with identical behavior, but local playback is less pronounced.  Dedicated UNIX servers with high-speed connections, but not flash servers. Internet connection is 50+Mbps to desktop – but again, local playback also shows the shuttering behavior, just not as much.
    It sounds like a Flash player or IE issue, but this is one of the largest combos on the net today, so I figure someone has gotten this to work using AME.
    Uninstalled/reinstalled Flash.  Hardware acceleration on/off, AVP on/off, etc.
    Since I have seen so many “jerky” playback posts associated with Flash, is this some sort of “known issue”?  I know that millions use h.264/Flash and IE daily, so I must be doing something wrong.  I realize the difference between IE and Mozilla Flash, but I can’t reconcile what I am seeing to just IE.  This is not a minor playback difference, but dramatic on 2 well-tuned systems.
    PP CS5, latest AME, latest Flash 10.x, etc
    Does anyone have examples of h.264 Flash output that hosts OK in the 512x288 to 786x432 range on IE? Can you provide link to output and settings that got you there.
    Thanks, H

  • Premiere Pro CC - Jerky Playback when using the Playback Option (Mavericks)

    I certainly jumped the gun and wished I hadn't, but Mavericks as sort of sunk part of my traditional editng approach. I know, should of waited to upgrade... alas.
    In PPro CC, whenever I have the playback optioned turned on for another monitor, I get stuttery/jerky playback in the program monitor and the playback monitor. When I turn off the feature, I get smooth playback, but have sacrificed the playback monitor, which is quite essential. Has anyone run across this issue or recognize what could be throwing things off?
    This was true in 7.0.1 and the latest update 7.1.0. -- I'm not sure its an Adobe issue, this may be fully on Apple... with high chances of that.
    To try and fix I made sure power nap was turned off on my Adobe Apps and that my Mission control spaces weren't separate for each monitor...
    Thoughts?

  • Jerky playback even on RAID 0

    Hopefully someone has a solution to this irritation!
    I am running Premiere Pro CS5 on a Dual Xeon 2.4Ghz, Windows 7 64bit with 24 GB of RAM and an Nvidia Quadro 40000. It is a new system with barely anything but CS5 installed.
    I render out PSD image sequences from After Effects and when I play them back on Premiere's timeline, 720p sequences can just about play smoothly however 1080p sequences stutter consistently.
    To resolve this issue I have bought an extra 2 WD Velociraptor 10000rpm drives and now have 3 of these drives striped as a single volume in a Raid 0 configuration. I've tested the Max Read of this new volume and I can get 326 MB/s out of it so no problems there.
    CS5 is installed on my system C drive. The footage and Adobe cache files are stored on the RAID 0 volume and the Premiere project is saved on an external eSata drive. I have Mercury Playback GPU Acceleration selected in Premiere, I have the latest Quadro 4000 driver installed, I dragged the imported footage onto the New Item icon in Premiere so it matches the sequence settings. Reducing the playback resolution with Premiere makes no difference whatsoever.
    It is so frustrating that the jerky playback is still happening. It is happening with footage shot on a Red also. The only possibilities I can possibly think of now are that there is some magic unit size I should use when creating the RAID volume, or whether AVG is somehow interfering, or if there is some feature on Windows 7 that I am not aware of that is doing things with the drives.
    Does anyone have any thoughts on how to resolve this?

    Don't expect image sequences to play back realtime; they won't.  Actually, that's not entirely true; if your I/O subsystem can produce very high transfer rates (which it sounds like yours can, at 300MB/s) then you might be able to if your image sequences are UNcompressed TIFF.  Any other compressed format (compressed/LZW TIFF, PNG, PSD) is not optimized for video playback and you're going to get stuttering.  You proved this yourself by rendering to an uncompressed .AVI file which you said played back perfectly.
    Your options are:
    Render your sequences to uncompressed .avi
    Render your sequences to a lightly-compressed format like Cineform (only slightly lossy)
    Save your image stills in uncompressed TIFF
    Or, you could just live with the stuttering -- remember, it's a preview issue only, your final mastered output file will be flawless.  If you simply MUST have realtime playback of what you already have because you're trying to time/edit a sensitive part, adjust the work bar to cover just that section and then render the section.  It will render to an intermediate format for preview which will play back realtime.
    PS: Ignore this hard drive reformatting talk -- If you're seeing rates of 300MB/s out of your RAID-0 then you're hitting the maximum transfer rate of SATA 3 (which is great).  The problem isn't your RAID-0.

  • Jerky playback

    All of a sudden I'm getting jerky playback of video. I've tried the usual fixes: trash preferences, delete render files, repair permissions, repair disk, but nothing has helped. This happens in timeline and also with individual clips in the viewer, on all projects, playing from a variety of hard drives. It may be a coincidence, but it started happening today right after I played a few of the videos on the new google video site. Also, when I open the Mac Finder, the columns are slightly jerky, snaping back and forth laterally, which leads me to guess the problem might be in my system rather than in FCP, so a re-install of FCP might not help. My other programs are working normally. Any suggestions? I'm running the latest FCP 5.0.4.

    Perhaps it is now time for the Harpoon solution (aka the Guinness solution in the mid and far west)
    for those not in the know:
    1. turn everything off.
    2. unplug firewire cables
    3. unplug power cords
    4. get up from well worn chair
    5. walk to refrigerator
    6. open refrigerator
    7. remove bottle of Harpoon (Guinness, local micro brew, etc)
    8. pop cap
    9. pour into glass ( you AREN'T going to drink it from a bottle, are you?)
    10. sip responsibly. enjoy the moment. think pure thoughts
    11. return to kitchen. If less than 15 minutes has elapsed, have another. Otherwise, retrurn to edit room.
    12. Plug everything back together
    12. fire up external monitors, VTR, external hard drives & computer in that order.
    does it work now? If yes, congratulate your self. If not, oh well, but at least you are in a much better frame of mind to begin some serious troubleshooting.
    cheerios,

  • IOS 4.2.1: Intermittent Playback and Static Issue Resolution - JVC KD-AVX77

    Hey guys, it appears that iOS 4.2.1 fixes the issue with the intermittent playback and static issues that I was having in my car. I just played two songs continuously with no issues.
    I have the JVC KD-AVX77, and with iOS 4.1, I was having nothing but problems with music playback. It had got to the point that it was intolerable to use my iPhone in my car.
    I am extremely pleased that it seems like Apple took everyone's feedback about this issue, and came up with a fix to it. Too bad that I've already stored my car for the winter.
    Please post your own findings. I know this issue was across multiple head units and car manufacturers.

    Same problem here. I have a 3gs and this intermitent static/hiss/lag happens when i connect through the usb on my toyota prius. This problem did not happen before the latest software upgrade. I have switched out the cables. Also tested on an ipod touch without the software upgrade and had no problem. It's a crazy annoying problem! Sounds a bit like listening to vinyl. I have also tried switching to airplane mode, but that didn't do anything. I have also reset the iphone while connected to the usb (the same way i frequently have to because of an earlier problem i've had with the usb failing to work in the car at all...) and that has not fixed it. I'm going to try connecting via bluetooth today and see what happens - i'm guessing that will be fine, but i don't like to listen via bluetooth.

  • Does adding RAM help solve iMovie4 jerky playback

    I have been reading threads about jerky playback in iMovie4 in large projects, after adding music from iTunes etc. My wife has a monster project and playback during editing has became very eratic. I have emptied cache, repaired the hard drive, repaired permissions etc. I have not tossed iMovie preferences. I have 23 gigs of space on the HD and a 250gig external FW HD that I bought after she started the project on the internal HD. I would like to know from you experts: 1. Would it help to move the project to the larger external HD? 2. Would adding RAM help (currently iMac G5 1.8mhz with 768 megs RAM)? 3. Is there any way to tell if the project will export to iDVD smoothly if it continues to look terrible in iMovie playback? I hate to go through a few hours of rendering for nothing. Thanks so much for your help. I always find good and useful info in discussions.

    Michael, there are some very useful applications that I highly recommend to keep your Mac running smoothly. As a defragmenter I use Allsoft's Disk Warrior that also has a very good directory repair feature. Check out also Drive Genius that has a host of useful features. Also get iMovie file fixers, invaluable tool that is free that will allow iMovie to import certain files in audio and photo formats that are greyed out and also has other features. I believe I got mine from Mr. Lennart Thelander in previous posts here. Cache Out is an excellent application to clear out cache files. I also advise you do a regular permission repair from Disk Utility in your Utilities folder that is on your Mac. These are basically my must have applications. As for copying your iMovie project to your external, just drag your entire project folder ( the blue one with the media and star folder(s) in it directly in the external hard drive. I find that iMovie is one application that requires a clean (defragmented) drive with ample space to spare. I defrag my drives if I trash files often from them, or if I notice erratic and jerky performance or slowness in response. I hope that some of my suggestions will help your in your editing.
