Fast re-encoding of finished videos

This card pertains to a resource available on the internet.

Assuming you are using a codec/container that supports splitting and combining (ex. MPEG.):

• Split video in to multiple segments (ex. 1 minute pieces.)
• Encode separate segments to new codec
• Combine the segments back in to one video

Some codecs (mpeg, maybe vp8/9) allow joining clips back together without any re-encoding as long as the properties are otherwise the same.

Obviously does not work for real-time compression.

But does allow datacenter scale sites to scale horizontally.
