When not to convert ASF to RM
- Skip RM for archival masters: lossy compression discards detail, so keep the ASF original.
- Keep a master copy: repeated exports stack small losses, so archive ASF before batch RM shares.
Limits
Starting point: ASF - ASF is Microsoft's streaming container that usually wraps WMV and WMA. Live-archive headers can confuse players; remuxing usually repairs them. Decoding paths for early Real codecs are scarce; try remuxing first. Encode RM (RV10 / AC-3) from ASF at a bitrate near the source, and confirm the audio track before converting.
