Greatbear recently helped the Streetscene section of Bristol City Council in an investigation in a serial flytipper.
DVD footage of the flytipper had been taken by a member of the public of flytipping activity but this DVD had other unrelated footage on that needed removal. The DVD was also damaged and needed slow, repeated reading to rip the MPEG stream successfully.
Using MPEGstreamclip it was then straightforward to trim the stream, resave and create a new DVD with just the necessary footage.
