FAQ
Does boosting video volume increase file size?+
Barely. When you boost audio volume with Loudify, only the audio track is modified. Since audio is typically just 1-5% of a video file's total size, the overall file size stays virtually the same.
Why is my video file so large?+
Video file size is primarily determined by resolution, bitrate, and duration. A 4K video at high bitrate can easily be 10x larger than 1080p. Try using H.265/HEVC codec instead of H.264 — it produces similar quality at roughly half the file size.
What resolution should I use for social media?+
1080p is the sweet spot for all social platforms. Most platforms compress anything above 1080p anyway, so uploading in 4K usually just means longer upload times without visible quality improvement.
