    FASTEST way to split a video file in half and save as two
    Pretty much what the title says.

    I have a 1GB (1.5 hr) mp4 file that I need to save as smaller parts. Actually 4 parts, I know the title says "half".

    I have Final Cut Studio...and I am a noob with it. I've exported several times in the past, but it was always to specific formats or codecs that people have requested. Many times it was simply to upload to youtube, so it was easy.

    I can figure out a way to make this work, but it certainly can't be the best. It either ends up creating a file half the size of the original, even though I cut up and exported a clip 1/4 of the total time, or it takes 20 minutes to create the file. Shouldn't it be able to QUICKLY save a section of the video since I don't want to change ANY of the settings? Just break it into parts?

    Gotta be a faster way...

    I have to upload this video to a site that requires file size of less than 300 MB.

    Thanks!

    Well, if you're not editing the footage per se, maybe you might want to look at another tool like Mpegstreamclip, or if your video file already has chapter marks that are recognizable you could use handbrake...

    With mpegstreamclip you can set in and out points and just export a portion of the file - of course, you may have to tweak the settings on the video export screen to find your balance between picture quality and file size, but you should be able to get your file down into smaller pieces without too much pain and suffering.

    With handbrake, if you have chapter markers in the file (since handbrake won't allow you to set in and out points based upon time AFAIK), you can create 4 exports from one file based upon chapter markers (ie: chapter 1-2 file 1, 2-3 file 2, 3-4 file 3, etc.) but this would depend on the file having chapter markers. The advantage of this over mpegstreamclip (if you have chapters) is the encoding queue - you can setup all of your exports at once then tell it to run the queue then walk away.

    Thanks! I will try those.

    And yes, I don't need to do any editing. Basically I ripped a dvd, then I need to divide into four parts for a website.

    Don't worry...all legit. The oven of the DVD content is having me do this for his website.

    Well, if you have the DVD still, and the DVD already has chapter marks in it (so you can skip forward and back and such), you may just want to re-rip with handbrake direct from the source with the chapters set for however many you want per file...
