Black bar cropping — a separate tab

• Automatically finds solid bars along the edges (dark letterboxing of screen recordings, cinema format, frames) — thresholds are configurable.
• Editor: full-resolution frame, red lines draggable with the mouse, precise numeric input and click on the preview.
• Batch mode: folder scanning, a table with paddings, its own ignore list, saving to the same folder (_cropped) or to a chosen one (with or without structure), result lists can be saved and loaded.
• Encodes with the built-in ffmpeg (H.264 + AAC) — audio is preserved, the file opens everywhere.

Speed: full hardware utilization

• Hardware decoding: NVDEC/CUDA (NVIDIA), Quick Sync (Intel), DXVA (AMD) — HEVC/4K up to ~2× faster, H.264 goes through the CPU where it is faster.
• The neural network runs on CUDA, frames are downscaled before analysis — same accuracy, higher speed.
• Parallel processing across all CPU cores; pre-filters (size, duration, format, name) cut off the excess before comparison.

Comparison: frame gallery

• Pair window: frames side by side, pager, counter, specification comparison with better/worse highlighting, deletion directly from the window.
• Gallery of all frames with pagination, a "More frames" button (up to 100), clicking a column opens the frame in comparison.
• Synchronized side-by-side viewing of two videos.
• Neural network weights are downloaded once on first launch; if the network drops — a "Retry" dialog with a list of already downloaded models. After that — offline.

Order in results

• Bulk deletion and moving of duplicates, deletion to the recycle bin first.
• Search with highlighting (an empty query shows an empty list, not the old one), pagination, row context menu, list export, saving/loading results, folder blacklist.

Little things you feel

• Hotkeys in a unified style Alt+1…Alt+7 (work in any layout), the list is in the F1 help.
• Russian and English without mixing: interface, log, dialogs, errors.
• Ads with labeling and a "Remove ads" button, license, update check, help for all features.

In this version we added parallel processing across multiple CPU cores and reworked settings management.

Main feature — multi-threaded processing

• You can now use all CPU cores for simultaneous frame analysis. This brings a noticeable speed boost:
• pHash — up to 2–3× faster on large collections (especially noticeable when scanning hundreds or thousands of files).
• CNN+Faiss — about 15–20% faster (neural networks already use the CPU intensively, but we squeezed out extra performance).
• Enabled in the new "Scan Settings" window — just tick "Use multiple CPU cores".

Note the system load — it is recommended to close resource-heavy applications before starting a scan.

Convenient "Scan Settings" window

• All parameters (frame count, neighborhood size, adaptivity, black bar cropping, similarity threshold, CNN model selection and parallel processing) are collected in one place.
• The main window became cleaner and simpler.

UI and fixes

• Improved interface and fixed errors — the app is more stable, navigation is more intuitive.

Especially useful for: owners of large video archives (hundreds and thousands of files) — you will notice the difference in scanning speed. The update is free for all users.

What's new

• Extended format support — the app now works with MP4, AVI, MOV, MKV, WMV, as well as FLV, WEBM, M4V, MPG, MPEG, 3GP, OGV, TS, M2TS, VOB, DIVX, XVID, F4V, MTS.
• 7-item context menu — right-click any file in the results: open in player, copy path, rename, mark/unmark, delete, compare with paired file, open folder. All the actions you need in one place.
• Bitrate in video info — the bitrate value (in kbps) is now displayed under FPS with color indication: green — higher bitrate, red — lower. Helps you quickly decide which duplicate to keep.
• Fixed an error in synchronized viewing — no more access issues when installing on the system drive.
• Correct remaining time display during the comparison stage — the estimate is more accurate and no longer jumps.
• Other minor improvements and fixes — cleaner code, more stable interface.

We recommend updating for everyone, especially if you work with rare formats or have previously encountered errors when starting synchronized viewing.
