Mp3 to Mp4: Audio to Video

Completion alert — When a batch finishes, the success message stays on screen until you tap OK (it no longer dismisses by itself). Easier to understand problems — If something fails, you’ll see what went wrong next to each file, plus a short errors section you can scroll and copy from. When a file already exists — You can overwrite it, skip that conversion, or save with a new automatic name; you can also apply the same choice to the rest of the batch. Batch progress — Finished items are lightly highlighted while the rest of the batch runs. Defaults — Audio length is on by default in the text options.
