Default Exporting mp4 over 25mins causes error


Source footage is
mp4 - 1920 x 1080
data rate 42283kbps
total bitrate 42478kbps

I want to export to mp4 for use on youtube.

The only way I have been able to export is to use the quicktime setting then mpeg 4 640x480 h.264 1372kbps 30p which I know is wrong but nothing else works. I then set the options to 1080p and in the settings of the export screen set the bitrate to around 32768 anything less causes pixelation on the footage (it's video game footage). The problem is I get an error when I try to export anything above 15mins in length.

If I try using the H.264/avc option after selecting print to file I get the error "Could not use the selected format please confirm setting"

The settings am using are:
Frame Size : 1920 x 1080
Frame Rate : 60.00
Aspect Ratio : 1.0000
Field order : Progressive
Video Channels : YCbCr + Alpha
Quantization Bit Rate : 8Bit
Stereoscopic Editing : Disable
Sampling Rate : 48000Hz
Quantization Bit Rate : 24 Bit
Channel : 8
Render format
Grass Valley HQ Fine
Over Scan Size : 3 %
Audio Reference Level : -20.0dB
Resampling method
Area Average (Fast & Sharp)

Any help would be greatly appreciated as this is not a video game hobby project it's paid work, thanks.
