Failed to push frame 2 ways to fix this.
So while exporting from hitfilm4 express, Many of you may experience the Failed to push frame error while exporting. One of the many reasons for this happening is not having enough disk space! As the export begins the file of the export grows in size, and if there is no more space, it will fail on the frame it was trying to export to the file, But this is not always the problem, Another issue is people are exporting there 30 FPS media, as 60 FPS or higher, always export at the same FPS as your media! And if that does not fix the issue play around with the bit rate. I hope this helped you guys.
