Why convert FLV to AVI?
- A converted copy keeps the original file intact for comparison and future edits.
- The output can be tested in the destination workflow before the original is archived.
- A separate copy makes it easier to compare the old and new behavior.
- Conversion is useful when the destination has a strict format requirement.
Will quality change?
Re-encoding can soften fine detail and change the file size. Keep the original master if editing or archival quality matters. Review the file in the application where it will be used.

Platform compatibility
The output is a AVI file. Use an application or device that accepts that format, and test the result on the destination platform if compatibility is critical.
When not to convert
- If AVI support is uncertain on the destination device, test a sample before processing a large batch.
- Do not use a converted file as the legal or signed original when signatures or metadata must be preserved.
- Do not overwrite the source; keep both versions until the output has been approved.
