Subtitle Edit 5.4.0 released

[niksedk]

Subtitle Edit 5.4.0 is out - 23 days after the 5.3.0 release, collecting the work of 12 betas and 4 release candidates.

What's new since 5.3.0

• New look: a more compact and polished UI - almost all windows redesigned in one modern editor look, with live theme switching and new SVG icons that are sharp at any display scale
• New themes: Nord, Midnight Cinema and Sakura, a visual theme picker with preview cards (Settings > Appearance) and background art for the video player and waveform
• Sync subtitle to audio: ffsubsync-style offset and frame rate detection, plus Sync audio track with live preview
• YouTube timed text (.ytt/srv3): pens, positions, preview and a styles window
• Export: D-Cinema SMPTE 2014 as MXF track file, Excel dialogue list (.xlsx) with chosen columns, and Blu-ray sup with an HDR (BT.2020 PQ) palette
• Check for updates: install and restart on Windows, Linux and macOS
• Auto-translate: source and translation side by side, translate selected rows together with context, new Opper engine
• OCR: optional video preview, Video OCR of chosen time ranges, and new LightOnOCR-3, LFM3-VL and QARI-OCR (Arabic) models
• ASSA: ASSA draw with text, groups and animations, a CapCut-style "Apply advanced effect" gallery with six new caption effects, and image-based export that draws ASSA styles and many more tags
• SubRip reader rewritten: tolerant of damaged files and 2.6-12x faster
• Multiple replace works like SE4 again: categories, flat rule list and edit in place
• More: custom error rules (regex), auto-wrap while typing, reload when the file is changed by another program, record speech to the text box, and many new shortcuts
• Translations: all language files synced with English, plus new Romanian and Croatian UI translations
• Bug fixes and minor improvements

A big thank you to everyone who tested the pre-releases, reported issues and contributed code and translations - and a special thanks to Anthropic for sponsoring a Claude subscription used in the development of this release :)

Thank you for the continued development of this wonderful software.

I'm looking forward to exploring all the new features in 5.4.0.

And I still hope that one day,
a little "Magic Switch" will be added to the waveform panel,
allowing us to switch between subtitle layers of the secondary subtitle file.

That would be the cherry on top! 😊

Many thanks! Thank you so much for this truly wonderful program. It has provided immense support to both amateur and professional translators—and to me personally, in my studies within the social sciences. The "bookmark" feature, in particular, has been invaluable; it allowed me to record my own notes alongside the comments and insights of experts, effectively turning these entries into a comprehensive reference. Thank you once again, and I wish you continued success. If I might make one request: it would be great to see the bookmark feature further developed—perhaps by making it easier to view, adding options for different colors and icons, and allowing for multi-line entries.
Wishing you continued progress!
