Frequently Asked Questions
Will increasing the volume distort the sound?
It depends on the original file. We use advanced audio normalization. However, boosting an already distorted track above 300% might introduce noise. We recommend starting with a 150% to 200% boost.
Does it reduce the visual video quality?
Absolutely not. Our engine copies the original video stream without re-encoding it and only modifies the audio stream. Your video's visual quality remains exactly the same.
What is the maximum file size?
Because StudioVid processes everything locally in your browser memory via Web APIs, there are no strict server-side limits. You can boost massive files safely.
Are my files uploaded to the internet?
No. We use Web Audio APIs and WebAssembly to process files strictly on your machine. Your data is 100% private and never leaves your computer.
