Cutting x264 encoded video to a few parts

Hi all,

I would like to ask for help on how to cut a video into 10minutes per part to be uploaded to youtube (it's my 1st time to try uploading video on youtube, please advice if there is anything else that I need to know).

Any free application that can do the job? (can application like MeGUI do the job?) I would prefer the cutting without the need to re-encode the video as the video is already encoded at bitrate=256 so I don't want the quality to drop further.

mkvmerge can split into time-based segments but it can only split on key frames. You could also cut before encoding to maximise the length per segment.

What do you mean by key frame? And by that, what are the limitations? Sorry, newbies here.

Its in .mp4...The length is about 45 minutes. So I guess I need to cut it to 10min-10min-10min-10min-5min.

Video Bitrate = 256
Audio Bitrate = 24 HE-AAC + PS (HE-AAC V2)

Code:
mp4box -add "X:\<your>.mp4" -split <time in s> -new "X:\<video-split>.mp4"
for example

Code:
mp4box -add "F:\fraps\gta.mp4" -split 600 -new "F:\gta-split.mp4"
makes 10 minute splits of my gta.mp4, which are named
gta-split_001.mp4
gta-split_002.mp4
...

and so on

the last file is <= 10minutes

What is the software that you use? I will give it a try.
