A method and system is provided for segmenting blocks of video data into chunks for consumption by player devices to create a new block to improve overall chunk creation. In one embodiment, issues that occur at the PCP block boundaries are handled by creating two chunks, one from the tail of content from the previous block and the other from the start of the new block, with the sums of the two chunks approximately equal to the target duration, improving manifest and chunk cadence creation. In another embodiment, chunks are created when the sink 104 requests a new manifest regardless of whether a proxy chunk timer pulling data from the PCP block has expired or not.
