    Hi All -

    I keep having problems with my x264 codec crashing my quicktime and iMovie '09 when using it. I was actually just using it a few days ago but it keeps causing crashes. Not sure what may have caused this. I should note that I have tried installing different codecs but I went back to remove them.

    Has anyone else encountered this?

    OK. Genuine H.264 is a part of the standard installation of the QuickTime frameworks. What do you expect from x264 that you can't get with H.264?

    I guess I am confused then on the difference on H.264 and X264. Are they the same? I thought X264 was suppose to be higher quality than H.264 when it came to exporting videos.

    H.264 is another name for the MPEG-4 AVC (formally, ISO/IEC 14496-10 - MPEG-4 Part 10, Advanced Video Coding) published standard. x264 is an open source clone of H.264 that is released under the GNU GPL.

    The name implies that the developers have done their best to make x264 behave like H.264, but without using H.264 code. You may want to use the x264 codec to handle the occasional x264 video that you receive from other sources. However, you have genuine H.264 on your computer out-of-the-box. There is no reason for you to use x264 to encode your own video.

    That definitely helps. Thank you for explaining that.
