Limits
Starting point: YUV - YUV holds raw planar pixels with no container or compression. Dimensions must be set by hand since headers carry no size. Decoding paths for early Real codecs are scarce; try remuxing first. Encode RM (RV10 / AC-3) from YUV at a bitrate near the source, and confirm the audio track before converting.
