Data can be serialized in such a manner as to facilitate later delta encoding, even when the serialization is performed using a lossy compression algorithm or an algorithm in which portions of the serialized data are encoded relative to other portions which may be modified. This can be achieved by approaches including preserving keyframe information across modified versions of a file, duplicating information from a previously created compressed file when serializing a later version, or adding change information showing differences between versions of a file during the serialization process.
