When Should You Use RM vs DV?

Use RM When...

If legacy streaming, realplayer content is your end goal, RM is the smart pick. Its widespread compatibility and small footprint make it a universal choice.

Use DV When...

Choose DV for dv camcorder capture, legacy video editing. It balances quality and file size better than most alternatives in its class.

RM vs DV: Key Differences

  • •RM and DV diverge on compression: lossy compression for the source, lossy compression for the target.
  • •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •How transparency is handled: DV does not support alpha channels — transparent areas in the source will become opaque.
  • •Storage footprint: Small, optimized for dial-up streaming for RM vs 13GB per hour in standard definition for DV.
  • •RM is optimized for legacy streaming, realplayer content while DV is designed for dv camcorder capture, legacy video editing — choose based on your specific workflow needs
