This streams can contain a lot of potential sources of errors like incorrect timestamps, an overflow of the timestamps (pts overflow), reception disorders, reconfiguration of the multiplex with change of the aspect ratio, video mode or the audio format… The additional data in this streams (DVB-SI-data for program info, teletext, etc…) can also make problems. I am also using Shotcut to edit recordings from television broadcast stations (directly captured DVB-S transport-streams from satellite) so i know this problem. Not only Shotcut, incorrect timestamps are an problem for all video editors and also for mediaplayers. Unfortunately, Shotcut depends heavily on accurate timestamps in the source file to ensure that each edit is frame accurate. I hope that are all necessary information. I am using following Shotcut settings for the export:

The exported video has following properties (.mp4 container):įormat profile : settings : CABAC / 3 Ref Framesįormat settings, Reference frames : 3 frames

The source material has following properties (.ts container):įormat profile : settings : CABAC / 6 Ref Framesįormat settings, Reference frames : 6 frames I am using Windows 10 and the newest Shotcut version. When I am exporting the video with stereo sound and AAC I get this disturbances too (downsampling 5.1 to stereo). I saw that there was already a bug with crackling noises at the start in 2019. Im getting crackling noises at the start of an exported video with Dolby Digital AC-3 for about two seconds.
