Last month, I came across stinkybread's AVSync repository and tried using it to sync a few video files. The concept was great, but the results weren't ideal when working with low-quality source videos containing the dub I wanted to retime onto a high-quality reference video.

The original AVSync approach extracts scene-change keyframes, matches them visually between videos, sets timeline anchors, and time-stretches the audio between those points. However, when working with heavily compressed or low-resolution sources, visual keyframe matching produced very few reliable matches, leading to sync issues.

Realizing that both my low-quality source file and the high-quality reference file contained matching original-language audio tracks (e.g., Japanese or English), I realized we could compare those original audio streams directly instead.

Working in VS Code with GitHub Copilot, I developed and refined this audio-to-audio strategy:

Cross-correlate matching original-language audio streams to build an editorial "recipe" (detecting FPS differences, cuts, missing eyecatches, and reference-only sections).
Apply that exact edit recipe to the foreign dub track and retimed subtitles.
Mux the corrected dub and subtitles back into the high-quality reference video container.
After extensive real-world testing (including a successful 53-episode batch run), the audio-to-audio workflow has proven very reliable for production use.

You can check out the fork here:

What's next:
I plan to apply what I've learned from the audio-to-audio pipeline back to the original video-to-video concept, making visual matching more robust for cases where matching audio tracks aren't available.

I would love to get your thoughts, test results, or feedback!

Thanks for reading,

I’m Jon, the developer and publisher of SmartCut64.

As everyone here probably knows, the VideoReDo editing program stopped being updated after the sad passing of its developer, Dan Rosen. I still use it almost daily, but there were more and more files that I wanted to edit that it couldn't import or export... 10 bit, HDR, etc. So I developed my own app, specifically keeping to a similar GUI and working process, so it could be an immediate, easy transition. I tried other apps that promised "smart-re-encoding" and no disrespect, but I never found them as easy and faultless to use.

So... SmartCut64. A native 64-bit editor for Windows 10 and 11 to replace VideoReDo. It includes Ad-Detective and Remuxing, and unlike VideoReDo it can handle:
  • H.264 High 4:2:2
  • H.264 High 4:4:4
  • HEVC Main 4:2:2 10-bit
  • HEVC Main 4:4:4
  • AV1 Main, 8-bit 4:2:0
  • AV1 Main, 10-bit 4:2:0
  • VP9 Profile 0, 8-bit 4:2:0
  • VP9 Profile 2, 10-bit 4:2:0
  • MPEG-4 Part 2 - DivX/Xvid-style video can remain MPEG-4 Part 2 - VideoReDo imported it but converted output to MPEG-2, H.264 or HEVC
  • Opus, FLAC, Vorbis, TrueHD, DTS-HD, ALAC and PGS

More information is here: https://linekerpandi.com/smartcut64. The Personal licence is currently £4.99 as a one-time founding price for the first 250 purchasers, then it's £19.99. It covers two activated computers, includes 12 months of updates and email support, and is not a subscription.

If you want to try out the GUI then there is an evaluation version - it has no time limit, but video exports are permanently watermarked and therefore fully re-encoded. Clean remux, packet-copy and smart-render delivery require a paid activation.

If anyone tries it, I welcome feedback. And if something does not work as expected then let me know, including the details of the source codec, container, hardware and export route. I've tested it with every type of file I can think of, but really want this to be definitive.

To be clear: SmartCut64 is an independent GPL-3.0-or-later project and is not affiliated with, sponsored by or endorsed by VideoReDo or its owners.

cheers

I found that a lot of my rips contains more audio tracks and subtitles than I actually need/user. These can take up surprisingly much space. I've been stripping these manually over the time. Now I've developed a nice tool which can automate this process with simple configurable logic. You can inspect what the app wants to remove before allowing it, so you have the complete overview and control of every thing.
Other cool stuff, like subtitle+nfo download, poster+fanart view, and too much to mention here, is also included. Give it a spin and let me know what you think? There is an optional leaderboard so you can see how your spacings stack up to others :)
