If you came upon audio only issues while loading GoPro 7 HEVC files into Hitfilm Express, you may wish to read this post. It displays a workaround to solve the problem.
Hitfilm Express GoPro 7 Black Video is Only Audio
‘When recording with my GoPro 7, I have recorded in 1440 @60 and 4k @30 and every time I import the videos into Hitfilm, they only come up as audio files. I can play them just fine through Windows Media Player. I have tried changing the video compression through my GoPro to HEVC instead oh H.264 + HEVC and that still doesn’t make a difference. I also have version 1.8 firmware which should be the latest frameware. Anyone have any ideas why this could be doing this? Thanks guys.’
GoPro records in HEVC codec which is compressed and not suitable for editing. First you need to convert your footage to an edit friendly codec like DNxHD or Apple ProRes. Use HD Video Converter for that. Same app can be used to trim videos.
How to convert GoPro 7 HEVC H.265 files to DNxHD or ProRes for Hitfilm Express?
Step 1: Start up HD Video Converter as an HEVC H.265 video to Hitfilm Converter.
Step 2: Click ‘Add File’ to import your source media to the program.
Step 3: Select output format
* If you are on a Windows PC, from the “Profile” bar, choose ‘Avid DNxHD 1080p (*.mov)’ as output under ‘Avid Media Composer’ column. (See the screenshot above)
** If you are on a Mac computer, choose ‘Apple ProRes 422 (*.mov)’ as target under ‘Final Cut Pro’ catalogue.
*** Note that this converter program can only output Apple ProRes and DNxHD video up to 1080p, if you want to preserve 4K quality of your source files, you need to select “4K Video” > “4K H.264/MPEG-4 AVC Video (*.mp4)” as target format. To export 4K files, please make sure your computer has enough power to process 4K. If not, simply select Apple ProRes or DNxHD as output format depending on your OS.
Step 4: Custom video and audio settings (for advanced users)
Click ‘Settings’ button, the ‘Profile Settings’ panel pops up, on which you are able to modify video and audio settings like resolution, bit rate, frame rate, sample rate and audio channel.
Step 5: When ready, click ‘Convert’ to start transcoding HEVC H.265 files to Hitfilm supported format. As soon as the conversion is complete, click ‘Open Folder’ button to locate the generated files and now you are able to open them in Hitfilm for further editing smoothly.
