H.264 Exports are corrupted during last few seconds of the exported clip

If you are using the Hardware Encoding feature when encoding directly to H264, I would suggest trying the Software Encoding. It's a slower but more reliable render, and I think it looks better too.

Has this been resolved? I've been having the exact same issue with all of my h.264 mp4 exports. Last 5 seconds freeze frames and doesn't properly export the full video. I've even tried exporting a prores file then bringing that into media encoder and making a h.264 mp4 out of that file and I still get the same corrupt result. This has been an issue for me with the lastest 2 versions of premiere. I have to export a prores file, open premiere CS6 and import that prores file and export the mp4 file that way. An exremley annoying workaround for an editor that works in a fast-paced agency.

Where do your clips come from? Phone? It sounds like it could be a problem with Variable Frame Rate video, there are somewhat consistent issues using that. You can use Shutter Encoder to create a constant frame rate. Use something like ProRes to edit better and not loose quality.

Hi Davis Jackson,

We're sorry to hear about this. Let us know the version of Premiere Pro that you are using. Also, are you playing the exported media in QuickTime player? If so, have you tried importing the exported media in Premiere Pro & checked if it's playing properly in Premiere? 

Thanks,

Sumeet
