RealMedia Variable Bitrate vs Flash Video

Why convert RMVB to FLV?

• The new format may support a feature the source container does not.
• The result can be reviewed without changing the file that other people still use.
• FLV is more appropriate for the target application, device, or delivery channel than RMVB.
• Compatibility is the main reason to convert when another person or service cannot open the source.

Will quality change?

FLV output uses a standard video codec and may drop subtitle, attachment, or metadata tracks. Test playback on the target device. Keep the source if you may need to adjust the conversion later.

Quality controls

Options can adjust output dimensions, audio bitrate.

The file is processed on the server because the conversion requires a server-side engine or a utility operation.

• RMVB features without a direct FLV equivalent may not survive the conversion.
• Review the converted file in the destination application before deleting the source.
• Batch results should be spot-checked before publication or delivery.

Platform compatibility

The output is a FLV 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

• 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.
• Avoid repeated lossy conversions when quality matters; start from the highest-quality source available.
