The size of the file shouldn't be an issue -- assuming your computer doesn't have a marginal or slower processor.
But try using the free download VLC Media Player to play the file. Default media players, like Windows Media Player, often leave a lot to be desired.
Thanks for the suggestion, but I tried both vlc and wmp. Neither will open the mp4.
I have a medium-high end i7 cpu.
Any other suggestions?
What's the resolution of this file? Is it a plain old 1920x1080 high-def mp4?
Maybe it's size does make a difference. I've never experienced a limitation before -- but then again I've never tried to create a 2 hour mp4 before. Though IMHO, a 2 hour video isn't that excessive. Unless it is.
Yeah, it's a 1080p one...nothing fancy. I used one of the publishing presets for Apple TV, iPad, etc. that are available in PE 12.
I wouldn't have thought around 2 hours is excessive either, but I'm really suspicious of a ~4GB limit.
I can just split it into 2 mp4s that are each less than 4GB and confirm that works for me.
I'll update the post when I try that...
Confirmed. I created 2 files that are about 2GB each and I can open those files fine. I didn't do anything special...I just hacked the project to roughly half (1 hour instead of full 2 hours), published to mp4, then undid my changes and then hacked to the other half and then published to mp4...to achieve two 2GB mp4s.
It's a pain, but it works. Hope it helps somebody else...I hope that Adobe also fixes this too!
I'm not sure it's an Adobe issue, weslowsk. Unless you have other 4 gig, 2-hour MP4s that have been able to play on your computer.
Good point. But it is an Adobe issue if PE 12 lets me publish an mp4 without giving me a warning or letting me know that the file I'm about to generate won't be readable. After I generated the original 4GB+ mp4, I felt like saying, "Thanks, Adobe, it would have been nice to know that I couldn't open this mp4 BEFORE I published it."
Why would a piece of software let me generate a file that is unusable? It's subtle, but Adobe has to share some of the responsibility.

No this is not an Adobe issue.
Adobe or any video software does not need to tell you: Hé your file is over 4 gig it might not play on your computer or exceeds the 4 gig limit (when it the latter it wont even export).
Many factors can play a roll in the playback of the file: resolution, bitrate, length, pc specs, player.
