When you play or edit some of your 4K HEVC video files, an error message is likely to pop up saying your application fails to decode HVC1 video. What is going on? Actually, HVC1 is not a video format like our familiar MP4 file, instead, it is a format tag or codec ID associated with the H.265/HEVC video compression format. You know what, HEVC/H.265 codec has two common FourCC, HEV1 and HVC1, which are code points used to signal different packaging of the stream in the video container. You can check video codec using MediaInfo to identify the codec id strings.
I'm not really privy to much of the technical differences or industry-specific stuff. In a nutshell, if your camera or recording device outputs a format tag of "HVC1" for HEVC video, it doesn't work for the applications that only recognize HEVC HEV1 videos. Fortunately, this problem can be simply fixed by video transcoding or re-encoding. And this post will show you how to convert HVC1 to MP4 for hassle-free playback and editing.
If you're not that tech-savvy enough, WonderFox HD Video Converter Factory Pro is absolutely your ideal choice. As a novice-oriented video and audio processor, it's equipped with a wide variety of A/V formats and predefined profiles so that you're able to convert HEVC HVC1 files to MP4 in only several mouse clicks. The WYSIWYG UI makes your video processing much smoother and more flexible than you might expect. Meanwhile, thanks to the batch video processing mode and hardware acceleration support, it will save you a lot of time and energy.
Run HD Video Converter Factory Pro after installation, then get into the "Converter" module. Click on the "Add Files" or "Add Video Folder" button to import your multiple HEVC HVC1 video files. Alternatively, just drag and drop them into the main interface.
Then, simply click on the big profile image on the right side to open the full list of 500+ optimized presets. Switch over to "Video" category and choose "MP4" profile to convert HVC1 to H.264 MP4, or select "H265 for MP4" to convert HVC1 to HEVC HEV1 MP4.
After everything is all set, specify an output folder by pressing the down arrow icon on the bottom. Finally, hit "Run" button to batch convert HVC1 to MP4 with GPU acceleration enabled.
If needed, you're able to open "Parameter settings" window to modify video and audio parameters separately. The HVC1 to MP4 converter allows you to change CBR to VBR, adjust video frame rate, resolution, bitrate, aspect ratio, increase video volume and so forth.
As you see, it's pretty simple to convert HVC1 to MP4 with the right application, right? However, you're not recommended to convert HVC1 to MP4 online because it's quite inefficient, and even time-consuming. Every operation requires a good and stable network connection with file size limited, which is a great challenge for processing large-sized video file. By contrast, the desktop program is obviously the best choice. If you agree with me, just go ahead, and start your work. This app will not let you down, I promise.
