Frequently Asked Questions
Here are some common questions and answers about m4v file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I use RunConvert for wedding videos?
A: Of course—whether it’s for sharing, archiving, or surprising your spouse with a highlight reel, we’ve got you.
Q: Will subtitles stay synced after conversion?
A: If they’re embedded, yes. If they’re external (like .srt), they might need re-syncing.
Q: Is there a size limit for uploads?
A: Yes, but it’s pretty generous. We’re optimized for quick, efficient conversions—not full-length movies (yet!).
Q: What format works best for Windows Media Player?
A: WMV is the classic, but MP4 is usually a better modern option that still plays nice with Windows.
Q: Why would I even need to convert a video?
A: Good question. Maybe your phone records in a format your computer can’t open, or you want a smaller file to send over email. Sometimes, it's just about making it work better for social media.
Q: Can I change the video resolution when converting?
A: Yes, you can downscale or upscale during conversion—great if you’re saving space or prepping for a bigger screen.
Q: Will converting videos help with buffering issues?
A: Yes—smaller, more efficient formats mean smoother playback, especially on slow connections.
Q: Do I need to install anything to use RunConvert?
A: Nope—no installs, no downloads. Just open your browser, upload, convert, done.
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: Can I preview the video before downloading?
A: For now, downloads are final—but preview functionality is on our wishlist!
