How to create a Quicktime movie using Cocoa QTKit

I am trying to find some example code on how to create a short Quicktime movie in a Cocoa app. The sample code I've seen so far is all for capturing the frames from an external source (e.g. camera).
Also, I am looking for how to control the compression engine to ensure that I can create a small Quicktime file if there is a lot of frames with small amounts of change in them.
Any pointers would be greatly appreciated.

I´m looking for a solution to protect QuickTime files with a pwd that one have to enter after a specific time. Is it possible?
No.

  • How to find the frames-per-second of a Quicktime movie using Applescript?

    Is there a way to find out the real-time "frames per second" of a Quicktime movie?
    The only Applescript movie properties in Quicktime which I have found to be useful are "duration" and "time scale". The real-time duration of the movie in seconds is found by dividing "duration" by "time scale".
    But "time scale" only sometimes relates to any real time property. In some cases it does (2500 = PAL 25 fps, 2997 = NTSC 29.97 fps) but for many other movie types I've opened (DivX, flv, mp4 etc) the "time scale" is often reported as "600" even though the Quicktime movie inspector window will report a frame rate of 25, 29.97, 15 or some other number.
    Where does the Quicktime movie inspector window extract the FPS from, and is it possible to extract that same number, or calculate the real-time FPS of a Quicktime movie using Applescript only?
    Thanks.

    Thanks for this but unfortunately it only works for some movie types. For .dv .flv and .divx movies, this script correctly calculates the FPS. But for .mpg .mp4 and .m4v it does not.
    For .mpg movies I tested, the count of frames was always 1, so clearly the FPS calculation is always wrong.
    For the .mp4 and .m4v movies I tried, the FPS was always reported as 43, regardless of whether the actual FPS was 25 or 29.97. In all cases the count of frames was incorrect.

  • How do I make quicktime movies Fullscreen in iWeb?

    How do I make quicktime movies Fullscreen in iWeb? Can anyone help me please?

    You have to create a QTL file that opens the QT movie in the player. Based on the settings it opens in Full Screen.

    An alternative is to publish your movies to Vimeo and embed the movie in your page. These movies can play full screen.
    Or use DivX of Flash Video.

  • Can Premiere create a Quicktime movie that loops?

    I have some Quicktime movies (.mov) that I made in Director. I want them to loop by default, but there's no setting for this in Director that I can find. (Not getting any answers on the Director forum...)
    I know I can set Quicktime Player to loop movies continuously but I want the loop built in.
    I'm a total novice at Premiere but I have access to use it at work. Can I change an already-made non-looping Quicktime movie to a looping Quicktime movie using Premiere CS4? How? Or some other way (freeware)?
    Thanks for helping!

    I have never done this, but I think Encore will allow you to create a movie DVD where the final action of the timeline is to go back to the beginning of the timeline (I think this would be done by creating a DVD with no menu, just a timeline set as 1st play for auto start)
    But... ask in the Encore forum to be sure
    Thanks for responding. Sounds like learning Encore would be part of this solution. Will have to look and see later if thats even included in the Premiere I can use at work. 
    A looping Quicktime movie seems like such a simple concept - an Export checkbox: "loop infinitely".  Any ideas on why this is not something that could easily be implemented into Premiere, Final Cut, Director etc.?

  • Creating a QuickTime movie with the new Canon T5i  camera in iMovie 9.0.9.

    Help needed creating a QuickTime movie with the new Canon T5i  camera in iMovie 9.0.9.  The project is done and looks good...I need help understanding what settings need to be set so I can make a QuickTime movie in the highest quality that would fit the ratio of 16.9 to be sent out to my YouTube page.  I played around with some of the settings and have not come with the right setting for the video.  I want the highest quality with the lowest amount of megabytes…thanks

    I would suggest using SHARE/EXPORT MOVIE and choose 1920x1080 (if your source material supports this).
    That should work well in YouTube.
    If you want to go further with custom QuickTime settings,  here are some that should work, but in my experience, it will be no better than using SHARE/EXPORT MOVIE.
    follow the instructions below to create a .mov video that will work on YouTube:
    In iMovie, select Share > Export Using QuickTime
    Next, you may want to check your Options to verify that the following settings are correct:Video settings
    Compression Type: H.264
    Frame Rate: 30 is preferred. 23.98, 24, 25, 29.97 are also acceptable.
    Data Rate: Automatic
    Key Frames: Automatic
    Frame Reordering: Unchecked
    Audio/Sound settings
    Format: AAC
    Click Show advanced settings and choose Constant Bit Rate as encoding strategy
    Other settings
    Size: Choose the original size of the video

  • How to crop a QuickTime movie to delete black top and bottom areas?

    How to crop a QuickTime movie? I mean, a ".mov" movie that shows a black area on top and bottom, which I want to delete.
    I have tried with iMovie 8.0.5, yet its "Window - Cropping..." to fit, crop and Ken burns does not allow to select the area that I want, which is extra wide.
    Thanks.

    How to crop a QuickTime movie? I mean, a ".mov" movie that shows a black area on top and bottom, which I want to delete.
    Basically, you have two options. 1) You can use an application like MPEG Streamclip (free) which allows you to reset the top/bottom/left/right screen edges (i.e., crop the active viewing area) and then re-compress the remaining content as a new file (as recommended by QTKirk) or 2) if you have QT Pro, you can simply "mask" the player display which crops the display screen to the desired mask dimension and location within the original area. The advantage of the latter work flow is not having to re-compress the file which can be very time consuming. Since the latter method may seem confusing to some, I have prepared a "quickie" tutorial which may be able to "talk" you through the process:

  • How to create the "300" Movie Effect in FCP

    Would be eternally grateful if someone could tell me how to create the 300 movie look in Final Cut Pro. I've scoured the Interwebs for a tutorial with no luck.

    I think it's not as hard as people think, it just looks intimidating because there are no popup windows. Everything in the interface is on the top of the rooms. Just think if FCP had things this way...
    I learned to use color in a class in Cupertino (I'm a certified trainer in Color and FCP) but gotta say, it's just not "Mac-like" in it's interface. It was originally written for Unix as was Shake, so they look similar... but they really aren't that hard to learn. The certified training course in Color is only a 2 day affair. I could teach anybody color on a one on one in one day. Doesn't make them a colorist just as learning FCP doesn't make them an editor... but the buttons? yep 1 day.
    FCPs full training is 8 days for full level 2 certification, and even then, it doesn't cover everything you could do in FCP...
    I teach a 15 week course in FCP and STILL don't have time to teach it all. So what's easier to learn? Color.

  • How do I rent a movie using money in my iTunes account.  I had to enter at the iTunes gift card code to open the account, but now I can't figure out how to use this money to rent a movie; I opened the account several months ago but never used the money.

    How do I rent a move using moneyin my iTunes account.  I had to enter the iTunes gift ard code to open the account several months ago, but never purchased anything with it.  When I entered this code to rent a movie, the response was that it was redeemed.  What am I doing wrong?

    If you've already redeemed the card onto your account then its amount should be on your account - a card can only be redeemed once.
    To rent a film, find the film in the store and (if the film studio has made it available as a rental in your country) click on its Rent button. If you are beig prompted to review your account and enter credit card details then see if this post from mountaingoatgirl lets you do so without entering card details : https://discussions.apple.com/message/24303054 . If that doesn't work then you should be able to remove your card's details after entering them.
    As long as you account's balance covers the rental cost then only that should be charged. How purchases are billed : http://support.apple.com/kb/HT5582
    When making purchases, content credits are used first, followed by Gift Certificate, iTunes Card, or Allowance Account credits; your credit card or PayPal account is then charged for any remaining balance.
