Frequently asked questions

SSA to ASS FAQ

What is the best use for SSA to ASS?

Use SSA to ASS when a device, application or publishing workflow requires ASS. Review the output before replacing the original file.

Does SSA to ASS preserve the original quality?

The result depends on the formats. Lossless formats can preserve the decoded data, while lossy output may change quality, size or metadata. Keep the original until the result is accepted.

Can I convert multiple SSA files at once?

Batch support depends on the tool. When available, add multiple supported files and review each result before downloading.

Are my files uploaded?

Supported conversion runs locally in your browser during the normal workflow. The original file is not sent to zer.ai servers.

Why might a conversion fail?

A damaged file, unsupported variant, an unusually large input or limited browser memory can prevent SSA to ASS. Try a smaller, valid sample and check the file extension and contents.
