Symptom
CONV2 rejects an input, stops partway through, or creates no output file.
Check
Confirm that the input opens in another media tool, that the destination has free space, and that you can write to it. Note the selected container, codec, and encoder.
Resolution
- Retry with a built-in preset to reduce the number of variables.
- Change the output folder to a local writable folder.
- In advanced settings, choose a codec and container combination that the target player supports.
- If hardware encoding fails, select a CPU encoder and retry.
- Install the current packaged build if the error mentions a missing FFmpeg component.
Expected result
The conversion finishes and the output file can be opened. A source-specific error may still require a different input or codec.
Escalation
Include CONV2 version, operating system, package type, selected options, and the exact FFmpeg error. Remove private file paths before sharing logs.
