What happens when WTV becomes MP4

Source format

WTV is the video source or target format for this conversion path.

Target format

MP4 is a widely supported media container, commonly carrying H.264 or H.265 video and AAC audio.

What changes

The WTV container is read and the selected video and audio streams are written into a MP4 container.

Codecs may be transcoded even when the visible resolution and duration stay the same.

What is preserved
Duration, frame order, and visible dimensions are preserved unless you select trimming, frame-rate, or resolution changes.
What may be lost
Extra subtitle, attachment, chapter, or alternate audio tracks may be omitted when the target container or selected settings do not support them.
Codec and quality implications
Container names do not guarantee a codec. Quality and compatibility depend on the selected video codec, audio codec, bitrate, frame rate, and resolution.
Realistic limitations
A valid WTV extension does not guarantee that every codec inside the container is decodable. Corrupt, encrypted, or unusual streams can fail.

Conversion steps

  1. Upload a WTV file no larger than 1 GB.
  2. Confirm that MP4 is selected as the target.
  3. Open settings only if you need to change codec, quality, bitrate, frame rate, resolution, or audio behavior.
  4. Start the conversion. A healthy compatible worker begins processing immediately.
  5. Download the MP4 file and check the result before deleting your source.

Troubleshooting

The WTV file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The MP4 file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
The result has no sound or will not play.
Try a broadly supported target codec and verify that the source contains a decodable audio stream.

Privacy and file retention

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
