    Which program would I use to convert an mp4 to a gif?

    I exported an mp4 from iMovie, and it is of short duration (13 seconds) and low quality. I would like to convert this to a gif for easier view-ability on the web.

    I have found many, rather trashy, applications that would do this on Windows that often involve using trial software and places watermarks on your end result, and I would wish to avoid this.

    Are there any good, preferably open source and/or freeware, applications for OS X that can do this? I am running Leopard on an Intel processor.

    Many thanks!

    GraphicConverter will do the job. It is shareware, but is fully-functional before you pay the shareware fee. This app is so good that you will gladly pay the fee if you can afford it.

    I tried that and it wouldn't allow me. Are you sure?

    When trying to convert from an mp4 to a gif using Graphic Converter, I receive this erorr:

    The file format of the document movie.mp4 is unknown. But it seems to contain a JPEG datastream.

    Should GraphicConverter try to decode the datastream (this can maybe result in a crash of the application)?

    [Cancel] [Try to decode]

    Upon choosing [Try to decode] it just doesn't do anything.

    The mp4 is just a regular 13 second clip exported from iMovie.

    I did the conversion by going to File -> Convert & Modify...

    I then chose the movie in the left box and the folder destination in the right. I hit Go and then received that error I previously mentioned.

    Any ideas?

    Try opening the video first in GraphicConverter. Then select File>Save a Copy as....

    When I try opening the file first, or in general, I get that same error:

    The file format of the document movie.mp4 is unknown. But it seems to contain a JPEG datastream.

    Should GraphicConverter try to decode the datastream (this can maybe result in a crash of the application)?

    [Cancel] [Try to decode]

    Can you perhaps export the file from iMovie in a different format, like Motion JPEG?

    it is a true MP4? For example did someone use a different codec and save it as mp4 when its really a divx or xvid? Just a thought.

    I just exported as movie in iMovie. Doesn't that make it a true mp4?
