A-DAPT: Advanced Video Forensics Software for Digital Evidence Analysis

How A-DAPT Helps

A-DAPT simplifies the complexities of digital multimedia evidence by giving investigators a reliable, unified platform for processing footage. It eliminates the need to juggle multiple tools or rely on proprietary playback software, reducing delays and the risk of error.

Whether you're:

• A police officer reviewing multimedia from different sources.
• A legal professional preparing footage for court in a compliant and tamper-proof format.
• A forensic analyst detailed analysis of file content even frame-damaged video
• A regulator or investigator needing to highlight salient points in audio and video.
  ‍

A-DAPT streamlines every step, from acquisition and clarification to export and reporting. It helps you work faster, with more confidence, while maintaining the evidential integrity required in professional investigations.

What Can A-DAPT Do?

A-DAPT offers a complete toolkit for handling digital multimedia evidence from start to finish. Its capabilities include:

• Multi-format video playback
  Seamlessly play multimedia files including proprietary and omf formats
• Video clarification tools
  Enhance image clarity, correct distortion, and extract key visual details from poor-quality footage.
• Frame-by-frame analysis
  Review critical moments with precision, ensuring no detail is missed during examination.
• Still image and clip export
  Capture stills or clips in standardised formats suitable for evidential use or courtroom presentation.
• Redaction and Highlighting
  Obscure sensitive visuals or annotate and highlight salient details.
• Evidential logging and reporting
  Maintain a full audit trail with time-stamped logs, ensuring every action is recorded for legal compliance.
• Frame Rate Validation
  Cross-checks container header fps against derived frame-level fps — highlights mismatches, generates frequency graph over the full duration
• GOP Analysis
  Full I/P/B frame map across all streams simultaneously — flags anomalous frames, non-standard sequences, and re-encode boundaries
• Timeline View
  Gantt chart across multiple sources — automatically flags gaps and overlaps with exact duration displayed
• Compare In/Out
  Pixel-level RGB difference map between any two marked frames — white = difference, black = identical — detects sub-pixel manipulation
• Milestone Marker
  Set any frame as time-zero — timeline displays ±offset for collision reconstruction and event sequencing
• Audio Waveform
  Full waveform with live scrubbing — set audio markers, correlate to video frames, export for reporting
• Analysis Report
  Fully customizable PDF — MD5/SHA1/SHA256/SHA512 hashes, thumbnails, hex headers, frame rate graphs, macroblock analysis, motion vectors
• Concatenate
  Lossless stream linking — no re-encoding, original GOP structures and all metadata fully preserved
• Archive & Restore
  Full project packaging with MD5 hash verification on restore — colour-coded results (green = match, red = mismatch)
• Metadata Report
  Critical fields in bold blue, anomalous data in red — container, streams, statistics, GPS location, and vendor-specific headers

How can I analyse video without FFmpeg?

A‑DAPT is a forensic video analysis tool built on a fully proprietary parsing engine with no black-box dependencies. Because it does not rely on wrappers around FFprobe, FFmpeg, or other metadata parsers, you can directly compare its results against your existing tools to strengthen the confidence of your findings. It uses open-source libraries as DLLs only, maintaining strict LGPL compliance. This design gives you a transparent, defensible foundation for your analysis—one you can clearly explain and stand behind in court.

Tools like VLC and some other forensic tools use FFmpeg which is designed to try and play your multimedia file even though it may drop some frames to do so, A-DAPT can report on the whole stream and report any broken or damaged sequences.

The total number of frames that FFmpeg reports as playable is 71680 whereas A-DAPT reports 71700. Although those 20 frames  may not have any content that can be visualised those 20 frames may be relevant if you are carrying out timing calculations or want the audio to be in sync. (FFmpeg discounted the "P" frames 0 through to 8 plus some others with macroblock encoding issues)

FAQ’s

Q: Can A-DAPT validate whether a video's frame rate has been altered?

A: Yes. A-DAPT's Frame Rate Validation cross-checks the container header FPS against the derived frame-level FPS, highlighting any mismatches and generating a frequency graph over the full duration of the file, a key check for detecting tampering or re-encoding.

Q: Does A-DAPT analyse the internal structure of a video's frames?

A:Yes. GOP Analysis produces a full I/P/B frame map across all streams simultaneously, flagging anomalous frames, non-standard sequences, and re-encode boundaries that indicate a file has been edited or converted.

Q: Can A-DAPT show gaps or overlaps across multiple video sources?

A: Yes. The Timeline View presents a Gantt chart across multiple video sources, automatically flagging gaps and overlaps with the exact duration displayed, useful for reconciling footage from several cameras covering the same incident.

Q: Can A-DAPT detect if a frame has been manipulated?

A: Yes. Compare In/Out generates a pixel-level RGB difference map between any two marked frames, where white indicates a difference and black indicates the frames are identical, allowing analysts to detect even sub-pixel manipulation.

Q: Can I mark a specific moment as a reference point in A-DAPT?

A: Yes. The Milestone Marker feature lets you set any frame as time-zero, with the timeline then displaying the offset either side of it, useful for collision reconstruction and event sequencing.

Q: Does A-DAPT support audio analysis alongside video?

A: Yes. A-DAPT displays a full audio waveform with live scrubbing, allowing you to set audio markers, correlate them to specific video frames, and export the results for reporting.

Q: What does an A-DAPT analysis report contain?

A: A-DAPT generates a fully customisable PDF report including MD5, SHA1, SHA256, and SHA512 hashes, thumbnails, hex headers, frame rate graphs, macroblock analysis, and motion vectors.

Q: Can A-DAPT join multiple video clips without re-encoding them?

A: Yes. The Concatenate feature performs lossless stream linking with no re-encoding, so the original GOP structures and all metadata are fully preserved across the joined file.

Q: Can I archive and restore an A-DAPT case file?

A: Yes. Archive & Restore provides full project packaging with MD5 hash verification on restore, with colour-coded results confirming whether the restored project matches the original exactly.

Q: What metadata does A-DAPT extract from a video file?

A: A-DAPT produces a Metadata Report with critical fields highlighted in bold blue and anomalous data flagged in red, covering container information, streams, statistics, GPS location, and vendor-specific headers.
