Export via Quicktime Slow

Hi,
I am having a problem with exporting videos via Quicktime. Instead of taking all the cores on the Mac Pro it seems to take only ~10% of all the cores.
Is there a setting in iMovie that would allow me to actually make real use of all the 8 cores in the Mac Pro instead of having to wait 5+ hours for an hour of video to be encoded?

No.
iLife apps use only one core.
don't expect wonders from a 20$ app..
probably 'Grand Central', a feature of SnowLeopard http://www.apple.com/macosx/snowleopard/ , adds multi-core support..

How can I export via QuickTime in iMovie '13 (10.0)?

Prior versions of iMovie had an export via QuickTime option, which allowed me to select the file format, encoding settings, etc. After upgrading to the new iMovie, that appears to have gone away. The Share -> File option does not allow me that level of control over the output file. Has that functionality been removed from iMovie?

I'm also having trouble with this. The new version of iMovie lost a lot of its features and is clearly focused toward the social media side of things. After importing using SD cameras that import video in a *square* PiP format, I am finding it impossible to update any of my settings to export the video in any other format that wouldn't cut out the picture. Basically, the only settings I've found in the share option of the iMovie 10.0 cu off the tops and bottoms of all my recording. Previously, I used QuickTime settings to pick what format and quality I wanted to export in. Does anyone have any insight about how to export using, say, a 640 x 480 format or in being able to adjust to any format other than the standard ones giving.
Is there any other video software I can be using to import and export with that gives me more functionality?

Exporting on Quicktime slows computer down.

Even with 4 GB RAM, and 3.06 GHz Intel Core 2 Duo, simply exporting a few Quicktime videos slows the computer to a crawl, even with very few stuff being open....

Is there any thing that can be done to keep the iMac from turning in to a slug during the exporting?

I've had quite a few windows computers that I have installed QT in fact 4 since last winter and have never expierenced any slow down.

Exporting via Quicktime good Compressor=Bad

I'm perplexed! I send a 16:9 video SD out through Compressor and when i import that file into DVDstudio pro, it's 4:3 aspect.
Exporting through a self contained QT file and importing into DVD studio it retains its 16:9.
Why does this happen???

What preset or settings did you use in Compressor?

Cannot export to quicktime or send to youtube

Hi All,
This is a new problem. I have been doing this for months with no issue until this month.
It seems to have started when a preso I sent to youtube only went up partly. Instead of the full 20 minutes or so, it only took the first minute and a half. However, no error messages were returned. I actually assumed it all worked fine till one of my viewers pointed out it was cut short.
For the next preso I did, I just started getting an error message that the disk was full or the video file was bad. This happens when trying to send to youtube. I tried exporting via quicktime, but the resulting file ends up with no sound and is clearly causing quicktime some trouble. Quicktime menus slow to respond and quicktime just seems to be working hard on something when it should not be. It does NOT do this with other quicktime movies I have that have come from other sources. Then sometimes, exporting to quicktime will result in the same error I got when sending to youtube.
Any ideas on what the heck is going on here?

Ok guys, here is the solution.
The culprit is Quicktime 7.5
I took my system back to 7.4 and now find everything is working fine.
Here is a link to an article that outlines the process. It is basically as easy as downloading "Pacifist" and the Quicktime 7.4.5 installer. But this article gives the details.

Advantage of exporting using Quicktime?

Just a quick question, what's the advantage of exporting via Quicktime vs. iMovie?

It is all the same. iMovie uses QuickTime.
iMovie provides pre-sets that are useful for most purposes.
The chief advantage of Sharing using QuickTime is you have a lot of flexibility.
I use it when
1) I want to share in a codec other than h.264.
2) I want to share a movie as audio only
3) In older versions of iMovie, there was no 1080P pre-set, so I would export 1080P through this setting.

Export using QuickTime...

Hello,
I recently started my second video project for my family which is converting Video8 and Hi8 tapes to digital video and had a few questions regarding "Export using QuickTime".
I utilize a Digital8 camcorder to play my analog Video8 and Hi8 tapes with a DV FireWire cable so the camera does the analog to DV conversion when importing into iMovie 09. Next, I utilize the MPEG Streamclip to do the DV clip conversion using 720 x 480 (DV-NTSC) frame size settings and apply contrast & color alternations. Lastly, I import the new .mov clips into iMovie, create a new project, do some trimming and now ready to export.
Question: I don't plan to share to iTunes, iDVD, Media Browser, YouTube or MobileMe Gallery however I would like to export and put the video on a media center device. That leaves me with "Export with Quicktime" however there are quite a few export options, for example:
Movie to AVI
Movie to DV Stream
Movie to QuickTime Movie
Which export option is best to use in terms of no loss of video and audio?
Also, there is additional settings, Options button, to configure video settings (compression, frame rate, data rate, quality, dimensions) and sound settings (format, channels and sample rate & size). Are these settings or defaults good to go out-of-the-box or do I need to tweak?
Any experiences or recommendations on export options and video and sound settings would be appreciated.
Thanks,
Dave

"DV will import just fine into iMovie 09 however when you render or export, iMovie uses 'single field processing' meaning every other horizontal line of the video is thrown out. In effect, reduces the sharpness of the footage. By using MPEG Streamclip, I am converting it into another format and then importing it back into iMovie."
I'm aware of the problem and I'm very curious about your solution. How exactly do you avoid the field drop issue? I thought you said you went from DV back to DV, which I thought would not have any effect on the field issue. Most other reports of working around the issue involve de-interlacing with, eg. JES Deinterlacer.
"Format: H.264, 640 x 480, Millions
Format: AAC, 2 channels, 44100 Hz
FPS: 29.97"
These are the AppleTV export defaults I guess? You could accomplish the same thing by an export via Quicktime, and then you'll get more control. IMHO, Apple's presets were chosen to produce "pretty good" quality at small file sizes. That's certainly a reasonable approach and they probably made a very well calculated compromise. But my preference is to sacrifice time and disk space to eke out a bit more image quality if I can.
Either way, these settings are very close to what I would use anyway, if your original video is 640 x 480. I thought my SD camcorder gave a bit more resolution before it croaked. Sorry I can't check it right now. Just be sure you're not losing resolution in the process. You could also bump the audio to 48 kHz if the input audio is at that sample rate. In the QT export, the other thing you can adjust is quality level; the default for AppleTV is probably "Good" or "Better" and single pass compression. Choosing "Best" multi-pass compression will take longer and give you a bigger file. You'll have to judge whether it's worth it. And just because you can see things on your monitor doesn't mean you'll see it on your TV - you have to test.
It's frustrating, but there really is no right answer to all this stuff, because the choices you make depend on your source and your display, and everything in between.

Exported Project via Quicktime Conversion-Some scenes "tear" at the top

I have completed a 17 min project made up mostly of photo/stills. Some have motion added some dont---it doesn't seem to matter to my problem: when I exported the project using Quick Time Conversion I noticed as I checked it prior to using iDVD to burn it to DVD that during cross dissolves and some other transitions there was a "digitized tearing" or pixels slow in locking into place in the upper 1/5th or so of the screen. I had not noticed this problem in previewing the rendered project prior to export. Using FCE v3.5HD. Anyone seen this problem? Is there a problem with some of the transitions or was it something that occurred in the export? I tried to burn to DVD via iDVD so I could see if the problem was off the top of the screen, but apprently I did something wrong during use of iDVD. When the iMac ejected the DVD after burn, I tried playing on a set-top and it wouldn't play, nor could I get it to play in the iMac. I also had difficulty getting the iMac to eject this DVD.

It sounds as if you have multiple problems here. The first problem is that QuickTime Conversion is not the way to export to iDVD. You should export to QuickTime Movie.

I'm attempting to export a quicktime file to an AVI file via quicktime pro. Which settings would yield an uncompressed AVI file? There seem to be just a few options, would I choose cinepak?

Quality difference between exporting via Export vs. Export using Quicktime

In iMovie 08, is there a difference in quality between Exporting a movie at the largest available size via the "Export" menu item, versus using "Export using Quicktime"?
I have a very long movie of family movies (9 hours) and have been unable to do a straight export (gets to the end after 25 hours or so and gives me a non-descript "can't complete" error message), but would rather split it up into several smaller files than compromise on quality, if there is such a compromise using the Quicktime function.
If I do go the Quicktime route, what settings should I choose, or just the default. Also, Export using Quicktime option makes a .mov file. What file type does the straight "Export" function create?
thanks much!

What file type does the straight "Export" function create?
All presets are compressed as H.264/AAC content.
Also, Export using Quicktime option makes a .mov file.
The MOV file container is "generic" and may contain any form of compressed data compatible with the QT components installed on your system and which the accessing application will allow you to use. In the case of iMovie '08, proprietary and third-party components are not allowed even if installed.
If I do go the Quicktime route, what settings should I choose, or just the default.
You use the audio and video codec and settings best suited to the goals of your export. Since you have not mentioned what your are trying to do with your exported content, it is impossible to make any recommendations here.
I have a very long movie of family movies (9 hours) and have been unable to do a straight export (gets to the end after 25 hours or so and gives me a non-descript "can't complete" error message), but would rather split it up into several smaller files than compromise on quality, if there is such a compromise using the Quicktime function.
A 9 hour export at the largest (960x540) dimensions implies a 4.128 Mbps data rate which equates to a file on the order of about 16 GBs in size. As you did not mention which export/sharing option you were using or if everything was being done on a single hard drive, such an export may require a total of 48-64 GBs of available storage space for temporary, Media Browser, and target/duplicate file(s) plus free memory for rendering purposes. So one of your potential problems could be file space availability.
As a general rule, increases in the duration of your target movie may require geometric increases in either available file space or the time it takes to perform the processing. It is, therefore, usually better to "chunk" your projects (break them into smaller, more manageable segments than to process them as a single project/file) and process the segments independently. In addition most people will not watch a 9-hour movie in one sitting in any case. (I have gone as high as 5 hours but even the product of this effort amounted to less than 4 GBs of file space.)
To "chunk" an iMovie '08 project, simply duplicate your completed project as many times as needed and then divide each into manageable segments and deleting segments so as to remove the duplicated segments. I would likely consider 6 segments targeted at about 90 minutes each but division of content anywhere between 60 and 120 minutes would probably be considered "manageable" for most purposes.
In iMovie 08, is there a difference in quality between Exporting a movie at the largest available size via the "Export" menu item, versus using "Export using Quicktime"?
There should be no difference in quality if you use the same compression formats and target settings. Changing either the compression format (each of which may have its own particular characteristics) or the settings (such as the data rate which directly affects both file size and quality) will usually produce visual differences in your product.

Should I export via Export Movie, or Export using Quicktime?

Hello,
I am making a "yearly video" of our family video clips. The movie is 45 minutes long. I have an HD camcorder though I have uploaded all the video as "large" as suggested since I dont have a Bluray burner anyway. I know how to export as a DVD file, but if I just want to create my movie to play on my computer, what is the optimal way to do it where I loose the least quality? This way I can save the file for later, should a better "burning" situation come about in a year or two. Should I export movie as "HD" or use "Export using quicktime" or some other option?
Thank you!!

Sorry.
By all DVDs until the master, I mean any preview copies that are used to preview content only, not video quality.
I export a reference movie, which means a movie file that refers to all render and media files on my drives, instead of creating a new self-contained quicktime movie. By using a reference movie, I save drive space (they're much smaller). But reference movies will only work on a machine that contains all the media and render files.
I've used reference movies in Sorenson Squeeze before, so they may work in BitVice as well. But I much prefer Compressor to any other option.

Buffering video downlowds via Quicktime, when using a HSDPA USB modem.

Hi,
Does any one else experience very poor streaming performance via Quicktime, when using a HSDPA USB modem. Every time, when using the Quicktime player and receiving data via a HSDPA USB modem, there seems to be minimal buffering of that data, so that the video quality is extremely pixelated and virtually unwatchable; are there settings that can be altered to correct this problem? This issue seems to be so petty, yet Apple is unable to offer a solution? That doesn't seem right?
Regards,
mike_biz

Is this a file that Quicktime PRO is not able to open?
Yes. Your camera's native video format is MPEG-4 and appears to possibly be "muxed" with MP3 audio.
If not, is there anyway that I can convert this file to one that I can use on my Mac?
Try installing the free Flip4Mac component. Then try playing the .asf file in the QT Player.
Is it possible to upload from my camcorder via the included USB cable and convert directly through Quicktime PRO?
If your file plays using the Flip4Mac player component, you may then wish to consider purchasing full conversion codec which will allow you to export your DXG-305V files to any frame-to-frame synchronized QT compatible format in QTPro.
ADDED: Sorry about the duplication, too slow with my response.

Movie within Keynote, export to quicktime transition delay

I have a very strange problem I can't seem to figure out. I create a Keynote presentation every week that is used to show our announcements at our church. I create the keynote with automatic advancement, then export it to a quicktime movie (which is then put on an iPod and used to project at church). It wall works very well and I have used this for several years. Here's my problem:
I inserted a movie into a slide in Keynote, the movie is about 30 seconds long and I am playing about 10 to 15 seconds of it. I then have the slide transition to another slide. When I play the keynote it all seems to work great - however, when I export the movie via quicktime, it plays through the movie then hangs for 10 seconds or so at the end of the movie before making the transition to the next slide. It is apparently "stuck" for that time. I have played around with every setting I could find to see if I could get it to work right but nothing changed this behavior. I tried shortening the movie length under the quicktime tab in the inspector, changing the delay in the slide tab in the inspector, nothing.
To make matters worse I apparently can't just cut out the 10 seconds of offending material via quicktime pro as it somehow only registers by the slide number and I cannot get the index arrow to pick a portion of the movie to splice.
Its all very frustrating - I've spent about 3 hours on this silly thing this evening telling myself "it can't be this hard." But either I am really missing the obvious, or there is a bug in Keynote, or this just can't be done.
BTW I am using Keynote 09.
Any help would be very appreciated. For tonight I've given up on the movie and just cut that part out.
thanks.

You've found one of my frustrations...here's the way it works:
In keynote, you MUST set the slide delay for a movie to stay on screen, and you can see that you're able to transition before the movie is done by cutting the delay shorter than the movie. The draw back is, if you want the whole movie to play, you MUST set the delay to at least the same length as the movie.
When exporting to QT, this doesn't work. The export forces the movie to play in its entirety. If you weren't trying to cut the movie short, you'd still have to remove your auto advance delay so that it transitions after the movie plays. This is why you're seeing that long hold, it's counting your movie length AND the delay time you added in Keynote.
The only thing I can suggest is removing that transition delay and living with the movie playing through to the end. You could always trim the movie in QT Pro and use that in Keynote I suppose.

After exporting to quicktime file, the file has sound but no video, what am I doing wrong?

after exporting to quicktime file, the file has sound but no video, what am I doing wrong? The self contained movie box is not checked.

Hi
Did You go via Compressor ?
Did You use QuickTime Conversion ?
I don't
I do
• In TimeLine set In and Out-Points to the full Movie/Project
• Select ALL - Clips and Audio
• Go up to Sequence and down to Render Only - down to Mix Down Audio
• then Sequense and Render Selected - Both (Video and Audio)
• then Export and as QuickTime .mov (NOTHING ELSE)
• I use to do - Not Self-Contained as it saves both time and space
Your Start-Up (Mac OS) Hard Disk - Needs lot's of free space to work OK - I never go under 25Gb free space on this one,
Good Luck - Yours Bengt W

Problems Exporting to Quicktime. Would you use Profcast?

Using the new Keynote, which is promising, we recording a seminar that was 2 hours long. We wanted to distribute it via CD. We have tried to export it so many ways to Quicktime. We get the old "Your slideshow cannot be exported as a Quicktime movie. There's not enough disk space, or there was a problem with the file." Of course, disk pace is not a problem. We just found out that this is some sort of bug that the Apple community has been trying to figure out for years and has errupted again with this new Keynote version. We've tried the couple solutions posted elsewhere on the internet, and nicely summarized here: http://www.madebymark.com/madebymark/2006/04/keynote30expo.html
As with the author above, they haven't worked for us. And we don't have a stray "audio icon" that the author describes. Our Keynote presentation is very bare, with new fancy slide transitions or effects.
I'm thinking that Keynote cannot be trusted with audio presentations of over a few minutes. We recorded a nice four minute or so presentation and exported to Quicktime. It worked wonderfully. Has all the nice effects. When we tried a longer recording (10) minutes, all the sound and transitions were out of sync.
Our problem is that we record whole lecture and seminars. If Keynote has a glitch, we are then having to re-record. It's painful and expensive.
We were using Profcast, which allows us to import Keynote presentation and record the lectures. Now Profcast doesn't allow fancy transitions. It also doesn't (or did not) export to Quicktime. It exported to mp4 (I believe) which a Quicktime user could open. But the audio was perfectly timed with the slide pagination. And two other important benefits. The lecturer could easily start and stop the audio. If I'm not mistaken, that's not on option under Keynote. If you start the recording under Keynote, you're on until you finish. If you pause (I don't think there is a pause. I think you must exit) the recording, you end the recording. The final nice thing of Profcast (although I have not used it) is that you can export to GarageBand. At that point you can edit out extraneous material. I'm not sure what to do with it at that point. I don't think GarageBand allows you to export to quicktime. I think you can export to iTunes which is a type of QT. Assuming that one had to edit using GarageBand, that would require person to have iTunes to listen and watch the slide presentation, if I'm not mistaken. The other problem is that when you are using Profcast, as I remember (and I may be wrong on this), you lose all the nice transitions and effects. You still see the same slides with the same quality, but minus the effects.
ProfCast has proven a reliable workhorse, but without the effects. Quicktime is wonderful if you are not recording audio. If you are, nightmares ensue, and there seems little hope for an immediate solution.
Here are my questions. Beyond the few solutions for the Quicktime export problem, does anyone have any solutions? Any suggestions? We have a three hour presentation (it's huge) and are loathe to rerecord it.
Should we just stick with Profcast? Why or why not?
Oscar

Oscar I feel your pain !
We had similar problems from a recent seminar recording.
However I don't think it's length related. We recorded 15 presentations. 7 of which did not have slides. All those were fine with just our placeholder screen (25-ish minutes each)
Of the remaining 8 half exported finem, half crashed with the "disk full etc" error. All 8 presentations had slides imported from Powerpoint PC. Slide numbers ranged from 10 to 30. We could not determine a common denominator between the ones that crashed.
We tried removing transitions, deleting and re-inserting the original slides and a whole raft of other voodoo especially trying to hack the contents of the KN Package file in the hope of stumbling on to a fix ... to no avail.
This was a one-off live conference, no re-record possible. You don't want to hear this but we were forced to extract the audio and manually resynch All the presentations in Flash
You may have a better workflow, but you DO know you can control click the Keynote file, choose "Show Package Contents" and in there you will find all sorts of stuff including the .m4a audio file
This is a serious bug that render KN completely it's recording feature completely unusable.
But what has been most disappointing to me has been the absolute lack of any feedback from the stuff I have filed on this. Bug reports, Feature Enhancements, and the lack of comments from any of the Apple KN staff on this Apple KN board, does not speak well to the type of support for this product.
But here's the sting in the tail:
Having JUST completed the Flash workaround (at a cost of several thousand dollars in contracting) I just installed the KN 4.01 updater released today and all the files that would not export now do so just fine ! Grrrrrrrrrr.........
