I've had a look at the video and I think you'd struggle to challenge on the basis of the events it shows. OK, you aren't actually stationary for very long but you entered without a clear exit and you did have to perform a sequence of momentary stops due to the vehicle in front.
One potential argument which may have success is around the location being insufficient to pinpoint which box junction the PCN refers to (there are multiple ones along Goodmayes Road). See this prior thread which, while not relating to Goodmayes Road itself, has the same theme and includes a reference winning appeal before an independent adjudicator based on this argument.

The council will definitely not accept it, so you'd need to take it all the way to adjudication with the full £130 on the line. It's not an argument that has universal acceptance (as there's no specific legal requirement for a PCN to state the precise location), but if you include the previous decision by Edward Houghton, another adjudicator might find it persuasive (and/or Redbridge may not contest).
