Original Note:
This is misleading, this is merely a pilot taking a video of another airliner close to him. Contrails are a byproduct of hydrocarbon fuel combustion and can persist in cold supersaturated air. High bypass turbofan engines create more contrails per the Ulrich Schumann study http://elib.dlr.de/9247/1/aerscitech-2000.pdf https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
