How can I convert HEVC to MP4 on Windows 11 without losing quality

here's how you can use XMedia Recode to convert hevc to mp4 without losing quality. The magic trick here is a feature called "Copy stream only," which basically just repackages your video into an MP4 container without re-encoding it—so the quality stays exactly the same and the process is super fast .

Here's the casual step-by-step:

1. Open your file: Fire up XMedia Recode and click "Open File" to load your HEVC video .
2. Pick MP4 as your output: Go to the "Format" tab and select "MP4" from the dropdown menu .
3. Enable "Copy stream only": This is the golden ticket for preserving quality. In the video settings, look for the option that lets you copy the video stream without re-encoding it—this is usually found under the "Mode" setting, where you can choose "Copy" instead of "Convert" . This ensures you convert hevc to mp4 without losing quality because the video data isn't touched at all.
4. Double-check the audio: While you're at it, you might want to do the same for the audio. On the Audio tab, set the mode to "Copy" as well. This avoids any weird audio issues and keeps the original audio quality intact .
5. Add to queue and encode: Click "Add to queue" and then hit the "Encode" button. Since you're using copy mode, it should only take a few seconds to finish .

And that's it. No quality loss, no complicated settings to fiddle with, just a quick and clean container swap. If you ever need to tweak things later, you can play with the Preset settings (like "Slow" or "Very Slow") if you do end up re-encoding, but for lossless conversion, "Copy stream" is your best friend.
