Why can't I export in MP4?

Whenever I try to export a video in MP4, a message pops up saying, "Recording failed with Error: Failed to encode the video frame." I've exported the same footage from Hitfilm Express with no problems in MP4. Anyone know the problem?

There might be issues with the write location. Have you tried rendering to different drives / servers?

Let me take a wild guess:

You have Windows 7 and you're trying to export in 4K?

Or HD, using one of the data rate categories (best, etc.), instead of CBR. I know they don't want to encourage its use, but there ought to be a glue-on for the few Win7 limitations, it would save a lot of redundant posts, if anyone bothered to read it.

I'm using windows 7 pro 64bit, and I get the problem everytime regardless of whether it's UHD or HD resolution.
I never had this problem with Resolve 9 and 10. From 12 onward it's been a constant problem for me.

Would a newer version of Windows solve the problem?

There's been threads about the same issue. Apparently Resolve is accessing the OS API for H264 decoding/encoding and Windows 7 has a bunch of restrictions compared to Windows 8 and 10.

This is one of the reasons why Win 7 is not supported. Resolve 14 needs Win 10.

Thank you. Is there a recommended version of Windows 10 ?

I'm guessing it will be this (Windows-10-Pro-64bit-OEM-DVD).

Most people seem to be using Win10 Pro. I haven't had any problems so far with Win10 Home.

Thank you, Charles.

Good morning. Hello,

Yes, you may have h264 export problems on Win7. Win7 is not officially supported OS anymore.

I haven't had any problems so far with Win10 Home.

Me neither. And that's a Win7 Home upgrade.

It all depends on the format, some flavors not supported under W7 but under W10.

This is probably because Bryan does not use Davinci Resolve's MP4 and H.264 encodings (and probably does not have the Studio version)

@Bryan,
It's not nice to let everyone believe that W7 works well . If a publisher says: test and approved with W10: it must be respected.

Regards.

Hey, steady-on. I never said that Win7 works well. I simply stated that the Win10 Home I have running on one PC was upgraded from Win7 Home....although I did perform a clean Win10 reinstall subsequently (Current build 16299). Nothing more, nothing less. And yes I am running the free version of Resolve - so what ?

Really nasty to vilify someone like that. I think an apology is in order there Jean Claude.

Indeed, I read too quickly. Apology
