Common Issues and Solutions

- Issue	Cause and Solution
Video Quality Issues	**Cause**: Compression or export settings. **Solution**: Export at higher bitrate (8 Mbps), ensure proper rendering settings, check minimum resolution requirements, use H.264 High Profile codec
Upload Failures	**Cause**: File size or connection issues. **Solution**: Check file size and duration limits, ensure stable internet connection, try uploading from different device, reduce video quality if necessary
Playback Issues	**Cause**: Format compatibility. **Solution**: Ensure format compatibility (MP4 with H.264), check file size is within limits, verify aspect ratio is supported, re-encode with standard settings
Audio Issues	**Cause**: Incorrect audio levels. **Solution**: Normalize audio to -14 LUFS, keep peaks below -1 dBTP, use AAC audio codec, add captions for viewers watching without sound
