Frequently Asked Questions
Here are some common questions and answers about y4m file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
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: Will converting affect my video’s color quality?
A: Not unless you use a low-quality setting. Stick with recommended presets for rich, vibrant results.
Q: Can I convert to GIF?
A: We don’t support GIF yet, but we’re considering it. For now, try using a dedicated GIF tool after conversion.
Q: Can I convert videos for WhatsApp?
A: Yep! Convert to MP4 and try to keep it under 16MB for direct sharing. Perfect for memes, clips, or birthday messages.
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.
Q: Does RunConvert support batch video conversion?
A: Right now, we handle one at a time for quality control, but multi-file conversion is something we’re actively building.
Q: Can I mute the video during conversion?
A: Yes. Just select a ‘no audio’ option or convert the audio track to zero—it’s like video karaoke!
Q: Can I use it on my tablet?
A: Absolutely. RunConvert is touch-friendly and works just fine on tablets and iPads.
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: What’s the difference between MKV and MP4?
A: MKV is super flexible and supports subtitles and multiple audio tracks. MP4 is lighter and more universal. Think of MKV as the Swiss army knife, MP4 as the crowd-pleaser.
