#156: Full HD Material from Canon 5D treated as 1920x1088 --------------------------+-------------------------- Reporter: rmk | Type: defect Status: new | Priority: normal Component: undetermined | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | --------------------------+-------------------------- Full HD material from the Canon 5D is detected and treated as 1920x1088 resulting in a black padding of 8 pixels at the bottom when played or transcoded. Both Quicktime and Mediainfo report the display size as 1920x1080. Since I do not have access to that camera I cannot upload a file but material is publicly available, e.g. here: http://www.dpreview.com/reviews/canoneos5dmarkii/page19.asp Mediainfo output for the video track of a sample file: Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Baseline@L5.0 Format settings, CABAC : No Format settings, ReFrames : 1 frame Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 28s 700ms Bit rate mode : Variable Bit rate : 39.1 Mbps Width : 1 920 pixels Height : 1 080 pixels Original height : 1 088 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 30.000 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.629 Stream size : 134 MiB (97%) Language : English Encoded date : UTC 2009-06-18 12:26:06 Tagged date : UTC 2009-06-18 12:26:06 Color primaries : BT.709-5, BT.1361, IEC 61966-2-4, SMPTE RP177 Transfer characteristics : BT.709-5, BT.1361 Matrix coefficients : BT.601-6 525, BT.1358 525, BT.1700 NTSC, SMPTE 170M -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/156> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

I sent a hackish patch that avoids the issue, however it is questionable and the file could probably be considered broken - not to mention that it can be non-obvious which should be used. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/156#comment:5> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
#156: Full HD Material from Canon 5D treated as 1920x1088 -------------------------------------+------------------------------------- Reporter: rmk | Owner: Type: defect | Status: open Priority: normal | Component: Version: unspecified | undetermined Keywords: | Resolution: Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Comment (by yellow): As far as I've tested Quicktime crops bottom 8. Although Canon 5D MKII appears to have 8 rows of black this is not the case for the other cameras in the range which are also 1088 h264 AVC in a mov container, they actually have 8 rows of image data. Easy to see comparison of a QT decoded 1088 frame and a ffmpeg decoded frame overlaid in Gimp for example will show QT crops 8 off, ffmpeg gives full 1088 lines of usable image data, no so called black padding not surprising since there is more than enough data coming off the 18MP camera sensor, even line skipped without the need to add black padding. ;-) Why the 5D does black is odd. What does appear suspect with the Canon movs is that ffmpeg treats them as yuvj420 not yuv420 so when transcoding to say lossless huffyuv the full range luma levels in the original camera file are squeezed into 16 - 235 unless the movs are first remuxed to something like mkv. -- Ticket URL: <http://ffmpeg.org/trac/ffmpeg/ticket/156#comment:6> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
