Best Export Settings for Audio and Video
Before you start uploading to your microTuneUp account, get familiar with our recommendations for video resolution, settings, and formats. This will make uploading a painless experience, and you will end up with top quality web encodes for your videos!
Most videos will work, but here are a few guidelines for video and audio
- Codec: h.264
- Resolution: between 640px and 3840px (4K) wide
- Bitrate (recommended): 5,000 - 10,000 kbps
- Framerate: constant, 15-60 frames per second
- Aspect Ratio: Get crazy! We accept videos of any aspect ratio.
- Codec: AAC (Advanced Audio Codec)
- Sample Rate: 44.1 kHz
- Channels: 2-channel Stereo (not surround)
And now, a little more explanation on why these settings are preferable:
After you upload a video, we perform encoding on it - creating multiple derivatives for different use cases and environments (like mobile devices ) and we also get these versions ready to play on the web. Our video servcies have type detection and encoding settings (what we call Smart Encoding) so that live-action videos look great, and will be as efficient a file-size as possible (for smooth playback).
Within the MTU player, we'll use HTTP Live Streaming—or HLS—to deliver the best possible version of your video at any given time. This means that the player will switch quality streams depending on the internet speed available. If we gauge that your viewers have slower internet initially, but the quality picks up after a few seconds of watching, we'll automatically switch to a higher quality viewing stream as the viewer watches. They don't have to touch anything!
