Frequently Asked Questions
Help with characters, video imports, backups, and language settings.
Why is no character displayed?
Characters are not bundled with MoniV. Import a .moniv file into the library, or create a character. For a new project, finish converting an Idle video before displaying it.
What is the difference between .moniv and .monivproj?
A .moniv file is a character pack for display and distribution. A .monivproj file is a backup containing editing information. Use Back Up in the library to save a .monivproj file for future editing.
Why can’t I add my WebM video?
Check that it uses VP9 with alpha metadata, a size of 1536×1536 or 3072×3072, and a constant 30 fps. A .webm extension alone does not guarantee these requirements. Check the error message and export the video again with the required settings.
When do I need FFmpeg?
FFmpeg is needed to convert WebM videos. Install it from the editor. You do not need to install FFmpeg to display an existing, converted .moniv pack.
About FFmpeg lets you uninstall the copy managed by MoniV. Your projects and converted videos are kept. Reinstall FFmpeg when you want to add new videos.
I closed the app during conversion
Choose Resume Conversion in the editor. MoniV continues unfinished conversions using saved recovery data. If there is a problem, use Inspect / Repair in the library to check the project.
How are Hide, Archive, and Delete Permanently different?
Hide only removes a character from the desktop. Move to Archive removes a project from the library while keeping it available for restoration. Delete Permanently cannot be undone. Deleting an imported pack is a separate operation from archiving a project.
How do I change the language?
In the library, open App Settings → Language and choose 日本語 or English. Automatic uses English unless Windows is set to Japanese. The selection applies to all windows and is remembered on restart.
Character names, creator names, outfit names, and filenames are not translated automatically.
How do I collect information about a problem?
Open App Settings → Support Diagnostics to copy diagnostics or save a JSON file. The diagnostics exclude personal names, saved paths, and video content. Review the contents before sharing them.
