QuickTime Movies Playback Chokes

Yesterday, I made a big presentation in front of our entire company. My Keynote presentation had three embedded QuickTime clips. They were about 2-3 minutes each.
I had run the presentation back at the office several times without problems. However, when I was making the live presentation, two of the three clips choked. They stopped about half way to three-quarters of the way through. Fortunately, they didn't lock up the computer; I could click past them.
I was able to catch this in the run-through. I deleted one right before I stood up to speak. Nevertheless, this was very frustrating and disappointing.
Any ideas what happened? Could the files have become corrupted? The entire presentation was about 306 MB. Everything else worked without a hitch.

are you using an outside display? If the video card is driving another display some of the GPU power that would normally be available to crunch some of the quicktime files might be tied up powering that second display. Also if you had it plugged in without studdering and now have it when running off the battery it may be your energy saving settings limiting your CPU usage. Just some things to trouble shoot.

Why do my quicktime movies playback at double speed? Please help

Hello all, this is my first post.
For some reason all of the sudden my quicktime movies that are 2 months old or older playback at double speed although the sound plays back as normal. Any movies that are less than 2 months old are ok. All these videos have been taken with my digital cam which records files in mov. Also any of these files which i convert to flash also play back 2 time faster when i select the converted swf file. Please help as i have hundreds of files which are affeceted. Any new clips i record playback fine.
Also I copied and pasted a problematic video on my wifes newer pc and the clip still has the same problem.
Thanks in adavance

I think I figured it out.. didn't see that you could choose what type when importing.

FCP7 HELP - Exported quicktime mov plays differently than what I edited on the timeline. The playback shows the clips with ins and outs that are different than what I set in the clips when I edited - some are too early and the clips don't playback

Please help ASAP.
Specs: IOS 10.6.8
Processor 2.4GHz Intel Core i5
Memory 4GB 1333 MHz DDR3 -- Everything is edited, sourced, and stored on an 2TB external hard drive to make things go faster.
Editing with FCP 7
When I export the sequence I edited with quicktime, the playback video is very different from what I edited on the timeline. The playback has the clips with ins and outs that are way off than what I cut, and some of the clips don't show at all or have changed transitions. However when I play in the timeline in FCP, the sequence is fine, just the way I cut it.
The source of the clips was one long .mov that I cut into clips for the timeline. Everything has gone smoothly but the exported .mov is just so different.
How can I get the time codes of the clips to be the same in the exported .movs? I just want the quicktime .mov to represent my edit exactly.
This video is due tomorrow - if the solution is too time consuming, can I play within the FCP player window and Log and Capture?
Thanks,

What is your source material? Is it H.264? FCP does not work correctly with that material.
Click on a source clip in the FCP Browser, and once selected, type Command + 9 to see the item properties for the clip. Either report those properties, or take a screen shot of the item properties, and post that here.
Next, click anywhere in your timeline, and then type Command + 0 {zero} to see your Sequence Settings. Either report those Sequence Settings, or take a screen shot of the Sequence Settings and post that here.

Aggressively increase a QuickTime movie's playback speed

Greetings,
I know it is possible to increase the speed of a QuickTime movie to 3x its original recorded speed using QuickTime Pro's AV control from the menu bar.
I was wondering if there is a way to increase the speed in a much more aggressive manner. For example, capturing a flower opening or a sunrise. That is, an hour of video compressed into a minute or less.
Experimenting with AppleScript's "Set Rate" command yields uneven playback beyond 3x.
I didn't expect to find the capability native in QuickTime but I was wondering if there is software available for QuickTime to accomplish this?
All feedback welcome,
Andrew Ontko

It is available in QuickTime Pro. You need only think outside the box.
QuickTime Pro allows to "Add Scaled". This means that the source of your paste will match the "timeline" of the "other file".
So. You want an hour of video to play in one minute. That would become an extremely high frame rate that many computers couldn't keep up with. But QuickTime Player is designed to "drop" frames so your file (when viewed) may appear just as you wish.
You could also use the "Image Sequence" feature of QuickTime Pro to create your file. This new file would not have the excessive frame rate.
To use the "Add Scaled" feature simply extract your video track (not needed if their is no audio) and save as (new file).
Let's assume your video is 60 minutes in duration at 30 frames per second. That's a lot of frames (108,00 to be exact).
Human eyeballs and brains don't do well with more than 60 fps.
Try this:
Open a one minute audio file with QuickTime Pro. Also open your one hour video in a new Player window.
From the "video" movie and select all (Command-A) and copy (Command-C).
Switch to the audio movie, select all and choose "Add to Selection & Scale".
Open the Movie Properties window of this new (not saved yet) file and "Delete" the audio track. Save As, name and try this new file.
A "better" approach would be to export from your one hour video at a lower frame rate as "Image Sequence". Set the export frame rate to only send one new image file for each minute of file time (total of 1,800 "frames").
Be sure to export to a new folder or you'll have images all over your Desktop.
From QT Pro choose "Open Image Sequence", highlight the first file name in new folder of images, set the frame rate (you wanted 30 fps) and QuickTime Pro will make a new file.
I use Add and Scale to create various effects (video and audio). Your audio can sound like James Earl Jones to the Chipmunks and your video can play as fast, or slow as you like.

Problems with audio playback in QuickTime movs on site

I'm working with some clients, and posting QuickTime movs for review on my site. Everything was fine until this last pass, when suddenly, half the people said they could see the video, but not hear the audio. I'm posting H.264 video with AAC audio. Even more unusual is that the people with the more recent machines and software were the ones having trouble. The older cpus and software seem to playback the movs just fine.
And it seems to be affecting Windows and Mac users equally.
Any suggestions?

Help Please ::: Quicktime .mov into iDVD 5 playback or encode problem issue

Originally Imageready files burned into Quicktime. Importing Quicktime .mov into iDVD results in project which looked great in preview, but after burning images were elongated, flattened. I am stumped, especially given preview results would indicate no such problems but unsure where to analyze on the DVD burn end to check. Any tips on what/where to check? Have tried re-importing original ImageReady (Photoshop) files into new Quicktime .mov (original project was done on OS 9 fyi). But no change in results.. any help greatly appreciated.
iMac Mac OS X (10.3.9)

Thank you for the feedback. I wasn't privy to the process that converted these files originally but suspected the theory on compression/codec initially used.. may re-convert. Also will try Disk Imaging... seems that this is not an uncommon problem in the iDVD 5 world...

QuickTime Movie File-Uploads on iWeb but no playback on the internet

Hello, Forum Techies,
Always trying to go beyond and want a movie clip on my website, but I may have met my match
I have the following QuickTime Movie file uploaded to the web page as noted below.
The file extension is MVI_038-#3-13. The file size is 663.8 Mbs
The website space is 1 GB using 10 Mbs upload speed.
The movie clip does not play on the website.
Question arising: I believe the space is sufficient on the website, but not sure if it this is a internet speed issue? I have other movies mounted successfully on another website, but their file size is not a huge and the webspace is not as much.
Therefore, I am curious to know if it is an internet speed issue?
Here is the URL for the page that I have included the movie clip:
http://thebigbenmemorialtrail.ca/Backgrounder_Trail_Scouting.html
It's a well visited site internationally and because it is a major project in our County, documenting the construction of a new trail is an interesting feature to include on this website.
Hope there is a solution. And, YouTube is not an alternative because for some strange reason I cannot get signed on no matter what efforts have been made with Google and I am not able to find a channel that applies to this kind of a movie, which is not entertainment, musical, etc. It's an information-based movie.
Thanks!

This is the movie :
http://thebigbenmemorialtrail.ca/Media/MVI_0368-%233-13.MOV
It's not an extension, it's the filename. Sanatize it.
Size = 632MB (Megabyte)
663.8Mbs = Megabits per seconds = speed
Videosize = 1280 x 720px
Filesize after download = 10.3MB (download stops at this size)
Nobody will wait for this.
Resize you movie to something smaller ie. width x height = smaller filesize.
Use common sense.

How to export quicktime movie?

I was wondering how I can export a quicktime movie (camcorder film) to a smaller size but that can also be played on both Mac and PC computers? I tryed to export a couple time using encoding such as MPEG-4 but the movie accually was much smaller to view than the original and the second time I tryed to encode it at a bigger size, the movie played at the same sze as the original but at a lower quality because it was stretched.
Can anyone help me with this. I just want to export and save a quicktime movie into a playble formate for both mac and windows and also not taking up too much disk space either. Thank you.

One could write a book (I did) that explains what all the codecs do and where and when to use them.
You need only need to know where the file will be viewed and its source format.
As Rick has pointed out, most new digital cameras capture in DV (Digital Video) and they are nearly instantly ready for software editing (like iMovie). QuickTime Pro can also edit the .dv files.
Once you determine where the file will be viewed (the Web for example) you'll get an understanding of methods to "compress" the file to fit the planned playback.
Three major factors that reduce the file size:
The new dimensions (720X480 DV files) to Web 320X240 (DV uses rectangular pixels).
Reduce the "frame rate". If the source was 30 frames per second you can usually remove half of them (15fps). Use more fps if the source has lots of motion.
The codecs used. Compressor-decompressor is handled by the delivery format (.mov or .mp4). Some are more efficient and offer better quality when enlarged during playback. MPEG-4 is the most modern and will soon become the next generation of DVD (currently MPEG-2).
This is where your question can only be answered by you. The quality can be adjusted (some codecs offer "sliders"; good better best while others allow you to set a data rate) and only you know what is acceptable.
Rick suggests a "one minute" export and I agree. Use various settings and data rates and use your eyes to decide what is acceptable.
Don't forget that part of your capture was audio. If your camera captures only mono formats making the export into stereo does nothing but double the size of the audio track. The Advanced Audio Codec (AAC) format found in MPEG-4 exports does a great job of reducing the file size. You can control these settings at export, too.

IWeb and Quicktime Movie Upload 2013

Three or so years ago, I made a website using iWeb (the last version Apple produced; i.e. the current version), and I included some videos. The videos were from a digital (tape) video camera, edited with iMovie HD, and were old-format 640x480. I managed to work out how to set the movies to start quickly (before fully loading) using iMovie and QuickTime. I dropped the movie into a regular iWeb page, resized it, put the settings up with the iWeb inspector, and all was well. The movies played (and still play) on Safari and Firefox, on my Macs and on an Asus Windows machine I have. (They won't play on my iPad - if anyone can tell me why, I'd be grateful; I'll probably put the original DV through a more recent version of iMovie and QT, and upload again.)
I want to make another similar website. However, my camera is now a HD tape model, and I have made my peace with iMovie '11 and worked out how to use it. My machine is the latest Mac Mini, and so QT is the latest also. I run Mountain Lion.
I made a movie with iMovie '11, and exported a quality version. I opened it in QT and chose 'Export for Web' and selected the option which gives me three different sizes. After some struggles, I worked out how to put this into my uploaded iWeb (test) site (although I have to say that the instructions Apple's QT gives are not the clearest), and it works, even on my iPad.
My questions concern the code which QT says you should upload. The code in the <body>, I understand, and it's obviously necessary to play the movie.
But about the <head> tag QT says:
Please note, to properly validate as XHTML, the <style> tag and the first <script> tag should be placed within your page's <head> tag.
Here's the code QT says to paste into the <head>
<script src="scripts/prototype.js" language="JavaScript" type="text/javascript"></script>
<script src="scripts/qtp_poster.js" language="JavaScript" type="text/javascript"></script>
<link href="stylesheets/qtp_poster.css" rel="StyleSheet" type="text/css" />
However, the movie playback still seems to work without uploading the code for the <head> of the page. And there is NO <style> tag, and why only the FIRST <script> tag?
The <head> on the page iWeb produces for my test page already has a lot of code:
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <meta name="Generator" content="iWeb 3.0.4" />
    <meta name="iWeb-Build" content="local-build-20130116" />
    <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
    <meta name="viewport" content="width=950" />
    <title>Ed's Video Test</title>
    <link rel="stylesheet" type="text/css" media="screen,print" href="Eds_Video_Test_files/Eds_Video_Test.css" />
    
    
    <style type="text/css">
/*<![CDATA[*/
    @import "Scripts/Widgets/HTMLRegion/Paste.css";
/*]]>*/
</style>
    <script type="text/javascript" src="Scripts/iWebSite.js"></script>
    <script type="text/javascript" src="Scripts/iWebImage.js"></script>
    <script type="text/javascript" src="Scripts/iWebMediaGrid.js"></script>
    <script type="text/javascript" src="Scripts/Widgets/SharedResources/WidgetCommon.js"></script>
    <script type="text/javascript" src="Scripts/Widgets/HTMLRegion/Paste.js"></script>
    <script type="text/javascript" src="Eds_Video_Test_files/Eds_Video_Test.js"></script>
</head>
Questions:
1. Should I put the QT code in the <head> tag anyway, even though it seems to work without it?
2. If I don't put it in, does that mean the choice between the three movies doesn't take place? I don't have a smartphone, but the playback on my 27" screen, my Asus netbook, and on my iPad all look fine without the head code.
3. If I do put it in, where exactly do I put it, and do I need to replace any of the code that is already there?
4. The original iWeb drag and drop method still seems to work fine with movies direct from iMovie (and plays even on my iPad), but obviously you can only put one version of the movie on a page. Is there still a good reason for using the multi-size version which involves manually uploading the movie and opening the page after uploading and inserting code for every movie? For example, I have a very fast internet connection. Maybe it's kind to those with a slower connection to put up the smaller movies also?
And, since I'm here, I have a couple of slightly related questions:
5. I designed my site (it's non-commercial, just a trip report, but with a lot of pages) to not need any scrolling even on quite a small desktop screen (you click on from page to page like a book, but you can also navigate around sections more easily this way; anyway that's how I like it). But on the iPad, held horizontally, the width is resized to take up the full width of the sceen, so you then need to scroll down. It's really annoying me. Is there some code I could put in to tell the iPad not to do this (there are plenty fewer vertical pixels on my website's pages than on the iPad screen)? (I don't care about phones, because the site is photo-based so looking at it on a phone is pointless in my opinion. And netbooks with only 768 vertical pixels are not particularly important to me either, but the iPad screen is plenty big enough for the site to work the way I want it to.)
6. And I want to include slideshows of photos without using the iWeb/iPhoto system (which brings up an external window in a different colour). I want the user to be able to see the thumbnails, to start and stop an on-page slideshow, and for me to be able to put captions (descriptions) with the slides. There seem to be a lot of options, and I still haven't finished looking at all the ones I got from the web. But does anyone have a good recommendation - paid or free?
Thanks for reading this long thread, and for any advice.

See the second method described on this page for how to add the code to an HTML Snippet...

AE instance + QuickTime movie in Premiere exporting with jitters

I am making a video project with a AE project and a .mov coming from Google Sketup 8 into an Adobe Premiere Pro CS5.5 project. When I export only the AE clip with standard H.264 Deinterlaced settings the playback is super smooth but when I export the whole clip with the same settings there are jitters and blurriness apprearing in the clip (The effect could be compared to an old VHS playback sort-of).
My Premiere project is a 720 x 480 document NTSC 4/3 aspect ratio and both my .mov and AE project are that format.
Could it be that my framerate could be different in my .mov and in my Premiere project? (As far as I know, both my AE project and .mov are at 29.97 frames per second, but could be wrong).
My export settings are H.264, NTSC DV High Quality - De-interlaced - I tried both Progressive and Cubic pixels.
Any lead would be appreciated. Thank you!

Thank you for answering this, Terence. That worked. I was able to export as Slideshow, but for some reason only the .m4v version will open. When I export as QuickTime .mov, QuickTime can't then open the file (??).

Export a Full Quality QuickTime Movie for CD

Hello - I have an 11 min. movie, that contains mostly pics, but also some video - I will be giving it to someone to play on there computer, which will also project onto a screen, during a wedding reception. She just wants to be able to load it into her computer - what is the most effective way of doing this?
I thought about exporting to a 720x480 Quicktime movie, using Qtime Conversion in FCP, and H.264 compression - is there a better way, so that it will show the best quality? After burning the movie to a QT file onto a CD, I thought I would then give to her to download - is this the proper way to do this type of thing?
Any suggestions are most appreciated as always - thank you...

KL -
That might be fine... thing is you WANT to have her test it. Sometimes playing large files like this (yes, even at h264) can choke a pc pushing it out to a projection unit.
I like putting it back to tape and sending it full rez out of a deck or other video camera.
I never trust PCs to even play a DVD out.

ITunes movie playback, audio and video not in sync after upgrade to Mountain Lion

After upgrading to Mountain Lion I have problems with iTunes movie playback, and the audio/video at times stalls/delays, or skips a few seconds, or even gets out of sync. I feared this problem was isolated to my machine until I saw an article online: http://reviews.cnet.com/8301-13727_7-57489874-263/sound-stuttering-after-mountai n-lion-installation/. I have 2011 iMac 27" with 16G RAM and am running the latest iTunes and Mac OS X software, and shutting down extra programs doesn't help. Please let me know of any solution.

I also have this problem, and some videos will no longer play in iTunes.
I get a message that this video is not compatible with this version of iTunes. I have to open the video in Quicktime to watch it.
Unacceptable! This hardware and software is too expensive to have these performance issues.

FCP Quicktime Movies works well in iDVD, but not in DVDSP

Hello,
I work in a film school with several iMac & PowerMac editing suites running Final Cut Studio 2.
Every computer is set up exactly the same way, yet we are having odd problems with DVDSP on one of the PowerMacs.
From FCP6, we export self contained quicktime movies, that we then Compress, and then import into DVDSP. This system works well on all of our new iMacs, but on the 3 year old PowerMac, the resultant DVDs that it burns do NOT playback on any DVD Players at all.
Yet strangely, when I take the same QT Movie into iDVD on that computer, it burns a perfectly good DVD.
I have even tried bringing the QT Movie files and Compressor files from the Power Mac and transfer them onto an iMac and have been able to burn them fine that way as well. This is occurring with all the FCP projects on this computer.
Any help would be much appreciated,
Sincerely,
Marc Griffin

It could be a few things, but it may be that the drive itself is dirty or going. It sounds strange but there were people on the board who ran into issues where they could burn the DVD but not play it back on the same drive. Could be something became corrupted. Also people have noticed some strange things happening if an install of Studio 2 was done over a prior installation - it seemed to be most reliable by doing a fresh OS install then installing 2. Also does the computer have all the updates to the software? Are all the computers running the same OS? Have you deleted prefs and repaired permissions?
Also check your settings on the PowerMac, are you doing a proper build/burn? Did you set a first play? Are you using the same type of media?

Edit a quicktime movie in ilife?

is there any way of cutting down a quicktime movie i downloaded from limewire in size.
it is 703mb but i would like it a bit less in size so i can burn it onto a cdr, i have not got a dvd burner?
can you do this in i-life,like i-movie or something?
hope you can help.
thanks

I don't think so.
If the movie is going to be played on a computer (only), you could use QuickTime Pro (29$) or MPEG Streamclip (free) to convert it to a format such as h.264, which will preserve the quality of your movie while reducing the file size a bit. The CD will be playable on any computer capable of running QuickTime 7, but not in a DVD player.
That it's only good if the original movie is encoded in a format such as MPEG 1 or 2, Motion JPEG or similar. If the file is already a DivX file (which is likely given its provenance), it is probable that the h.264 file will take more disk space. In this case, it may be more difficult to compress the movie more than it already is, and I have no idea how to do it. (BTW if your file is in an .avi contender, it is likely that it is a DivX or a variant)
Note that if it's a DivX, even if you could burn the entire movie to a DVD, you'd need a DivX-capable DVD player (or a computer) for playback.

If you are referring to an MOV file stored on a data DVD for playback in the QT (or similar) media player and not a DVD "authored" for commercial DVD device playback, then it sounds like you encoded it incorrectly. Basically DVD devices have a limited data transfer rate and if this rate is lower than the total playback data rate (combined video + audio data rates), then some of the data is not transfered to your computer fast enough for smooth playback in your media player.
I would normally recommend compressing your movie content using the H.264/AAC codecs (most efficient Mac standard codecs) and set the "Optimization" pop-up to the "CD/DVD ROM" setting. This option will "package" the encoded content for playback directly from a DVD player that is compatible with data rate limit you impose for the encode. Another option would be to copy the file from your DVD to your computer drive for playback since hard drive data rate transfer is much greater than that of a DVD player.
