Frequently Asked Questions

Is the audio quality compressed?

No. FootageKit decodes the native audio stream and encodes it into uncompressed 16-bit PCM WAV, preserving the original dynamic range and sample rate (44.1kHz or 48kHz).

Can I extract audio from 4K and 8K MP4 files?

Yes. Because files are processed directly on your computer's CPU/GPU, file size does not matter. Drop 10GB or 50GB clips without errors.

Are my video files uploaded anywhere?

Never. Your video never leaves your computer, making it completely safe for confidential client shoots.
