CodecLens — Professional Video & Media Analysis for macOS
CodecLens is a powerful media inspection and visualization tool designed for video engineers, post-production professionals, streaming specialists, and anyone who needs deeper insight into how video files are built. Instead of just playing media, CodecLens lets you analyze it — revealing the structure, bitrate behavior, and technical details that impact quality and performance.
Understand Your Video at a Glance
Open any video file and instantly explore codec metadata, frame layout, GOP structure, profiles, levels, scan types, programs, audio loudness, and stream details. CodecLens presents complex media information in a clean, focused interface built specifically for technical workflows.
Bitrate Visualization
See how bits are distributed across your timeline with an interactive bitrate graph synced to playback. Quickly identify spikes, compression artifacts, scene complexity changes, and encoding inconsistencies — ideal for validating encodes or diagnosing delivery issues.
Quality Metrics
Use PSNR, AVQT, CAMBI, and VMAF graphs to identify and inspect quality issues.
Designed for Real Workflows
CodecLens combines Apple-native playback with advanced frame analysis, making it useful for:
• Encoding and compression analysis
• Streaming and ABR ladder validation
• Broadcast and interlaced/progressive inspection
• Codec experimentation and comparison
• Live playback with real-time media statistics
Fast, Local, Private
All analysis runs locally on your Mac. No uploads, no cloud processing — just high-performance inspection powered by industry-standard media tools.
CodecLens also supports SRT and RTMP streams for inspecting a stream from OBS or a streaming service.
Whether you’re verifying a final deliverable, tuning encoder settings, or learning how codecs behave, CodecLens gives you the clarity you need to see beyond the pixels.
CodecLens supports all major ABR formats (HLS, DASH), file formats (MP4, MOV, MXF, WEBM, MKV, AVI, M2TS, ...), codecs (H.264/AVC, HEVC, AV1, VP8, VP9, AVS3, ProRes, DV Videos, YUV, MPEG-2, FFV1,...) and much more. Includes opening videos in Photos app and remote http/s Urls.
