MP4 is a container format. The video inside (which is probably what you're talking about) is already compressed. If the compression is insufficient, you change codecs or parameters (eg, size). If you're trying to upload it to YouTube, than you need to convert it to a different container format, Flash Video; you should convert to .f4v, not .flv. Either way, the quality of the video will be affected.

  • How do I compress a video file on mac

    Please help!!  I have just created a movie using iMovie which is 175 mb. How do I compress it so I can email it to a friend?

    If the file is longer than a minute in time then it may be too large for email.
    Better to use an online file sharing service to send the 175 MB version.

  • How do I compress a video file so I can send it via email?

    I am trying to email a slideshow I just created in iPhoto.  My email won't accept the file because it is too large.  I tried to compress by right clicking on the file in the Finder application.  It gives me the option to compress it so I said yes.  It appears to have compressed it but it is still the same size and I can't email it.  What  am I doing wrong?  What do I need to do this?  I know people compress files all the time to send them. 

    You didn't say how long the slideshow is.
    FCPX has a preset which, at its smallest, downsizes the resolution to 240p. But a very long video might still not be small enough.
    So how long is it?

  • How can I capture AVHDC video files from Panasonic HD video camera??

    I just received a Panasonic HS300 video camera and can't copy the video files on my computer.
    I see several files in the CAM_HDD camera folder on the desktop. But the only relevant files for me to copy are the JPG photos. I don't see any video files.
    In the specs of the camera they write that I should have a Mac with an Intel processor. Is that the problem???
    I even tried to copy the files on a PC (I succeeded) and then brought them on my computer with a USB stick. It didn't work: again, the only relevant files that I could see were the JPG, no trace of any video (but they were indeed on that USB stick!!).
    How can I access those video files and use them in Final Cut Pro, or even iMovie??
    I'm becoming afraid that i won't be able to use that camera unless I buy a new Mac now!!!
    thanks!

    you need this: http://www.shedworx.com/voltaichd
    the native iMovie / FC AVCHD codecs are only for Intel Macs, the format is a highly compressed HD format which needs to be unpacked & converted for use.
    The powerbook may not be up to editing these files. expect a slow process of exporting & working with the footage.

  • How do I compress a video in iMovie 10.0.6?

    Hi everyone,
    I have been searching Google for advice on how to compress a video file in iMovie, but the versions others are using are older than 10.0.6. So, for example, there is no Share menu on the update from which to Export to Quicktime as they suggest. I want to get a 800Mb video down to 200Mb. Any suggestions?
    Thanks!

    The best you can do in iMovie version 10 is share to file and then change the dimensions in the next window.
    You can also share to file the original size and export it using QuickTime X.

  • How do I compress a video that 160mb to 25 mb for an email

    How do I compress a video that 160mb to 25 mb for an email

    After it's re-encoded using a lossy format, the OP could also use an application (of choice) to create a segmented file (rar, etc.) and send each portion in individual emails. Most severs won't allow anything over 5 GB, so the user could choose 4 GB segments and the receiver could use a free un-rar app (quite a few available in the App Store - even more for Windows users) to extract the video.
    Just some random thoughts...

  • How do I import my video files from old iPhoto - in time machine - to new iPhoto?  Photoes came across, video said incompatible.

    how do I import my video files from old iPhoto - in time machine - to new iPhoto?  Photoes came across, video said incompatible.
    i have moved from a mac pro to a mac mini,
    Mini now has mavericks and latest iLife stuff, I clicked import, was all good, then at end, no videos came across.
    Is Mavericks,/iPhoto having a compatibiltiy issue with some video formats....???
    Your help is appreciated gang.: )

    Please describe exactly what you did. In moving to a new machine no importing is involved. The best way is to simply connect the two computers together and drag the iPhoto library from the old one to the pictures folder go the new one and launch iPhoto

  • How do I copy my video files from iPhoto to iMovie. The two   hour wait to view all in iMovie puts the kibosh on my edit time.

    How do I copy my video files from iPhoto to iMovie? The two + hour wait for thumb nails and hour long wait looking for the right videos kills the time I have to edit.

    You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle. For that you need mpegStreamclip:
    http://www.squared5.com/svideo/mpeg-streamclip-mac.html
    which is free, but you must also have the  Apple mpeg2 plugin :
    http://www.apple.com/quicktime/mpeg2/
    (unless you are running Lion in which case see below))
    which is a mere $20.
    Another possibility is to use DVDxDV:
    http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm
    which costs $25.
    For the benefit of others who may read this thread:
    Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.
    If you are running Lion:
    From the MPEG Streamclip homepage
    The installer of the MPEG-2 Playback Component may refuse to install the component in Lion. Apple states the component is unnecessary in Lion, however MPEG Streamclip still needs it.
    To install the component in Lion, please download MPEG Streamclip 1.9.3b7 beta above; inside the disk image you will find the Utility MPEG2 Component Lion: use it to install the MPEG-2 Playback Component in Lion. The original installer's disk image (QuickTimeMPEG2.dmg) is required.
    The current versions of MPEG Streamclip cannot take advantage of the built-in MPEG-2 functionality of Lion. For MPEG-2 files you still need to install the QuickTime MPEG-2 Playback Component, which is not preinstalled in Lion. You don't have to install QuickTime 7.

  • How do i move a video file from the theater to the library for more editing? New version of iMovie.

    How do I move a video file from theater to the library for additional editing in iMovie. It is a new iMac so i guess i have the newest version of iMovie.

    Hi hilldw61,
    Welcome to the Apple Support Communities!
    I understand that you have added a clip or project to iMovie Theater but would like to continue working on it. When you upload the project to iMovie Theater, the original project remains in iMovie where you can edit it further. 
    Add, remove, and play clips and projects in iMovie Theater - iMovie Help

  • How can I delete hidden video files from the iPad?

    How can I delete hidden video files from the iPad?  These files were created on my MBA and when I changed the media type to iTunesU and then copied it to my iPad via iTunes, they did not appear.  I can see them using 3rd party software, but they don't have delete functionality.
    Thanks
    York

    Interesting note:  I can see the files when I use the search function, but when I tap either file, I return to my home screen.  The video does not open.  I can transfer the file to my MBA, and it plays fine, but I cannot figure out a way to delete them.
