#7008: Sony A7S progressive footage recognised as interlaced -------------------------------------+------------------------------------- Reporter: pbogdan | Type: defect Status: new | Priority: normal Component: avformat | Version: Keywords: sony a7s | unspecified scantype | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- It seems like the scan type of the below attached Sony A7S sample is not recognised correctly. The sample was created with the camera set to progressive. Also other tools from Adobe and Apple recognise the samples scan type as progressive. The video stream information indicate a ''(top first)'' scan type which I consider to be interlaced. Using ffprobe with ''-show_frames'' and ''-show_streams'' options the following values seem strange to me. FRAME: ''interlaced_frame=0'' (which indicates no interlacing and applies to all frames) ''top_field_first=1'' (which indicates interlacing and also applies to all frames) STREAM: ''field_order=tt'' (also indicating interlacing) To further check this behaviour I also took an actual 50i sample created with the camera into account. FRAME: ''interlaced_frame=1'' ''top_field_first=1'' STREAM: ''field_order=tt'' I can provide additional samples if needed. Thanks in advance, pb '''Files:''' 25p sample: https://www.dropbox.com/s/dm8zxre82g9tipw/sony_a7s_1080_25p_10s.MTS?dl=0 50i sample:
