Sequentia Nexus

Build a video workflow once. Run it on a whole folder.

Extract audio and subtitles, convert the audio, fix and sync subtitles, read image subtitles with OCR, merge or encode on your NVIDIA cards, and upload the result to your NAS, for every movie or episode in a folder, without typing a single command.

Windows 10 / 11 · free during the beta · 11 languages · All versions

The main window: script catalog, workflow and parameters

Everything your video library needs

Pick the steps from a catalog, set them up once: the app puts them in the right order and runs them on every video, movies and TV series apart if you like.

Extract

The best audio track and every subtitle in your language, sorted into forced, regular and SDH, also from MP4, AVI and MOV.

Convert the audio

AC3, E-AC3, AAC, FLAC, DTS, Opus or MP3, 5.1 / 7.1 upmix and an even loudness (EBU R128) for every episode.

Fix the subtitles

Clean tags and encoding errors, create a missing regular or forced track, resync the timing, add your own rules with a live preview.

OCR of image subtitles

Blu-ray and DVD subtitles turned into text, with a smart correction of the typical OCR mistakes.

Encode with NVENC

H.264 / H.265 on your NVIDIA cards, two videos at once with two cards, while the CPU converts the audio.

Hardsub and fonts

Burn subtitles into the picture (SRT, styled ASS, Blu-ray and DVD images); the fonts of ASS subtitles stay in the file.

Upload to your NAS

SFTP, FTPS or FTP, into the movies and series folders, each file as soon as it is ready, with resume if the connection drops.

11 languages

English, Italian, French, German, Spanish, Portuguese, Romanian, Russian, Turkish and Chinese, chosen from Windows at the first start.

How it works

No scripts, no command line: the steps are ready, you only choose them.

Pick the steps

Double-click what you need in the catalog. The workflow orders itself.

Set them up once

Languages, codecs, bitrate, rules. Save it all as a preset.

Run it on a folder

A check before the start, a live log, a ✓ for every step, an optional notification at the end.

A look inside

Dark and light themes, a parameter panel for every step, and help on every option.
