Corel VideoStudio x7 rendering problem

[okyou]

Hello,

I have encountered a rendering problem hope any of you can shed some light on how to solve my problem.
I have composed a 15 min video and everything looks good on the edit/preview screen. But when I tried to render this video to Mobile device at MPEG-4 AVG(1920x1080 30p 5Mbps), it always crashed around 30% finished with a pop up saying 'Corel VisualStiudio has stopped working' - A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available' . The strange part is that if I render on higher resolution such as MPEG-4 AVC 4K (3840x2160 60p 65 Mbps), AVI DV (720x480 16:9) or MPEG-4 AVC (1920x1080 30p 15Mbps) , all rendered fine without a hitch but the sizes are too large for my mobile device. Any format in the mobile device will crash in the same spot regardless what photo or video in that spot.
I also tried to replaced, deleted the photo in the crash location but it still crash on the same spot. Can anyone out there can give me some idea how to fix this crash problem ? Any help will greatly appreciated.

Hardware: Intel X5 with 20 GB ram, plenty of HD space.
Windows: Pro 8.1
Corel VisualStudio: X7 version 17.1.0.22 (64bit Ultimate)

Have you tried rendering to 5MB NOT thru the "Mobile" settings? Just put 5000 in the mpeg4 profile.
If you not rendering to 3gp file , no need to select mobile.

Thanks for your info. I tried your recommendation but it still stopped at the same spot. What else can I try ? Thanks

Strange, there is nothing special about 5MB, so in order to get this project done
render it to 15MB and convert with any video converter to 5MB.

That might do it. Thanks.
