1 of 3

• WAV (Waveform Audio File Format) provides uncompressed, high-quality audio ideal for editing and archiving
• MP3 (MPEG-1 Audio Layer 3) offers compressed audio with smaller file sizes, suitable for online distribution
• AAC (Advanced Audio Coding) delivers better sound quality than MP3 at similar bit rates
• FLAC (Free Lossless Audio Codec) compresses audio without quality loss, balancing file size and fidelity

Video file formats

• MP4 (MPEG-4 Part 14) widely supported format for online streaming and playback on various devices
• MOV (QuickTime File Format) commonly used for high-quality video storage and editing
• AVI (Audio Video Interleave) supports multiple audio and video codecs, offering flexibility in encoding
• WebM open-source format optimized for web-based video playback and streaming

Compression vs quality

• Compression reduces file size by removing redundant or less noticeable data from audio and video files
• Lossy compression (MP3, JPEG) permanently removes some data, resulting in smaller files but reduced quality
• Lossless compression (FLAC, PNG) reduces file size without quality loss, allowing full restoration of original data
• Higher compression ratios lead to smaller file sizes but may compromise audio or video quality
• Balancing compression and quality crucial for efficient storage and distribution while maintaining content integrity

Export settings

• Export settings determine the final quality and characteristics of audio and video files
• Proper configuration of export settings ensures optimal playback and compatibility across various platforms
• Understanding export options allows reporters to tailor their content for specific distribution channels or requirements

Resolution options

• 4K (3840x2160 pixels) offers ultra-high definition suitable for professional-grade video production
• 1080p (1920x1080 pixels) provides full HD resolution, balancing quality and file size for most applications
• 720p (1280x720 pixels) serves as a lower HD option, suitable for faster streaming or smaller file sizes
• Standard Definition (SD) resolutions (480p or lower) used for legacy systems or when bandwidth is limited
• Custom resolutions allow tailoring output to specific platform requirements (social media, digital signage)

Frame rate considerations

• 24 fps (frames per second) creates a cinematic look, commonly used in film production
• 30 fps standard for most broadcast television and online video content
• 60 fps provides smoother motion, ideal for sports or action-packed scenes
• Variable frame rate (VFR) adapts to scene content, optimizing file size and playback smoothness
• Higher frame rates (120 fps or more) used for slow-motion footage or specialized applications

Bitrate selection

• Bitrate determines the amount of data used to represent audio or video per unit of time
• Higher bitrates result in better quality but larger file sizes
• Variable Bit Rate (VBR) dynamically adjusts bitrate based on content complexity
• Constant Bit Rate (CBR) maintains a fixed bitrate throughout the file, ensuring consistent quality
