    Frequently Asked Questions

    Here are some common questions and answers about red file conversions ask by our users on RunConvert.com.

    Q: Can I convert video files shot in 4K to HD?

    A: Yep—downscaling from 4K to HD is super common, especially when you’re trying to save space or make uploads faster.

    Q: Can I convert old camcorder footage?

    A: Absolutely—those nostalgic AVI files? We’re great at modernizing them into MP4s you can actually watch.

    Q: Does converting reduce video quality?

    A: Not always. It depends on the settings you choose. Stick to high bitrates and compatible formats, and you’ll be golden.

    Q: Why did my video lose sound after conversion?

    A: That’s rare, but it could be a codec mismatch. Try converting to a format with AAC audio or reach out to us.

    Q: How secure is my video during conversion?

    A: We take privacy seriously. Your files are encrypted during upload and deleted automatically after a short period. No funny business.

    Q: Will RunConvert mess up my video’s aspect ratio?

    A: Nope, we keep it just as it is—unless you decide to change it yourself during conversion.

    Q: Can I convert slow-motion videos?

    A: Yes, but note: some slow-motion effects are software-based. Converting may flatten them into normal speed.

    Q: Is WebM better than MP4?

    A: WebM is great for web browsers and open-source fans. MP4 is more universal. It depends where you’re sharing.

    Q: How do I convert video for an Android device?

    A: MP4 is your friend here—works like a charm across all Android versions.

    Q: What happens if my internet cuts out during conversion?

    A: No worries, just re-upload the file when you're back online. Our system doesn’t store incomplete uploads.

    What is MKV (Matroska Video)?

    MKV (Matroska Video) is an open-source container format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. It is designed to be flexible and is often used for high-definition video content.

    MKV is a popular choice for storing HD movies, TV shows, and videos due to its ability to support almost any type of video and audio codec, as well as multiple audio tracks and subtitles within one file.
