Subtitle file embedding is here! Mugen Converter can now add subtitle files directly to your videos. 【Subtitle File Embedding】 You can add SRT, VTT, ASS, or SSA subtitle files as soft subtitles inside a video. The subtitles are not burned into the picture, so supported players can turn them on or off. The app also shows helpful details such as the selected subtitle file, subtitle count, final timestamp, and a plain-text preview, making it easier to confirm that the video and subtitle file match before converting. 【More Reliable Input Handling】 Videos selected from Photos or Files are now handled more consistently across normal conversion, subtitle embedding, and queued processing. We’ll keep improving Mugen Converter to make everyday video handling easier. If you notice anything, please contact us through the in-app support option.

Audio timing adjustment is here! Mugen Converter can now help you fine-tune videos where the sound is consistently ahead of or behind the picture. 【Audio Sync Adjustment】 For videos affected by Bluetooth speakers, playback environments, or other constant timing offsets, you can move the audio slightly earlier or later with a simple slider and create a corrected copy. 【Queue Support】 Audio sync adjustment also works with the conversion queue, so you can process it alongside your other video tasks while keeping each setting preserved. We’ll keep improving Mugen Converter to make everyday video handling easier. If you notice anything, please contact us through the in-app support option.

We made small internal adjustments to improve the overall app experience. 【Internal Refinements】 We adjusted the timing of internal behavior and user prompts so everyday video conversion feels more natural and comfortable to use. We’ll continue refining Mugen Converter step by step. If you notice anything, please contact us through the in-app support option.

We reviewed and refined the app’s internal behavior to make it run more reliably. 【Improved Internal Stability】 Internal handling has been adjusted so the app can manage feature states more appropriately at launch and in situations where network conditions may vary. Premium access has also been carefully refined so active subscribers can continue using the features available to them with greater confidence. We’ll keep improving Mugen Converter as a dependable video conversion tool. If you notice anything, please contact us through the in-app support option.

Introducing "Specialty Conversions" — a new category of purpose-built recipes, starting with MPEG-4 conversion for car navigation systems! Specialty Conversions is a dedicated space for conversions tailored to specific devices and use cases. This is just the beginning — more recipes are on the way.

This classic format ensures broad compatibility across a wide range of in-car players. You can fine-tune resolution, quality, and frame rate in three tiers each to match your car nav's screen, and built-in guidance explains what each setting does and how long the process takes. This update also includes improvements to file handling accuracy and overall stability after conversion. More specialty recipes are in the works. Got an idea for one?
