Hi there,
Apologies if there has been a similar request to this before. I'm trying to rewrap an old AVI file with dvcp codec to the .dv wrapper so that it's explicit when committed to long-term LTO storage that it's a DV file. I've been using an FFmprovisr command: ffmpeg -i input_file -f rawvideo -c:v copy output_file.dv This results in a DV file smaller than the AVI with a missing audio channel and other missing metadata. I've attached the results of mediainfo outputs of both below, AVI first. I've tried a -map 0 function which failed. I'm sure it's a simple audio command but I've not been able to find anything online that has helped me so far. Many thanks in anticipation, Joanna White Media Archive for Central England AVI DVCP: General Complete name : /Volumes/scanner/FOR LTO/6775 DV.avi Format : MPEG-4 Commercial name : DVCAM Format profile : QuickTime Codec ID : qt 2005.03 (qt ) File size : 37.3 GiB Duration : 2 h 56 min Overall bit rate : 30.3 Mb/s Encoded date : UTC 2012-11-15 11:44:17 Tagged date : UTC 2012-11-15 13:11:49 Writing library : Apple QuickTime TIM : 00:00:00:00 TSC : 25 TSZ : 1 FileExtension_Invalid : braw mov mp4 m4v m4a m4b m4p m4r 3ga 3gpa 3gpp 3gp 3gpp2 3g2 k3g jpm jpx mqv ismv isma ismt f4a f4b f4v Video ID : 1 Format : DV Commercial name : DVCAM Codec ID : dvcp Duration : 2 h 56 min Bit rate mode : Constant Bit rate : 24.4 Mb/s Width : 720 pixels Height : 576 pixels Display aspect ratio : 4:3 Original display aspect ratio : 4:3 Frame rate mode : Constant Frame rate : 25.000 FPS Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Bottom Field First Compression mode : Lossy Bits/(Pixel*Frame) : 2.357 Stream size : 30.1 GiB (81%) Language : English Encoded date : UTC 2012-11-15 11:44:17 Tagged date : UTC 2012-11-15 12:42:53 Audio #1 ID : 2 Format : PCM Format settings : Little / Signed Codec ID : sowt Duration : 2 h 56 min Bit rate mode : Constant Bit rate : 1 536 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Bit depth : 16 bits Stream size : 1.89 GiB (5%) Language : English Encoded date : UTC 2012-11-15 11:44:17 Tagged date : UTC 2012-11-15 12:42:53 Audio #2 ID : 1-0 Format : PCM Format settings : Big / Signed Muxing mode : DV Muxing mode, more info : Muxed in Video #1 Duration : 2 h 56 min Bit rate mode : Constant Bit rate : 1 536 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Bit depth : 16 bits Stream size : 1.89 GiB (5%) Other ID : 3 Type : Time code Format : QuickTime TC Duration : 2 h 56 min Frame rate : 25.000 FPS Time code of first frame : 00:00:00:00 Time code, striped : Yes Language : English Encoded date : UTC 2012-11-15 12:42:53 Tagged date : UTC 2012-11-15 12:42:53 DV REWRAP: General Complete name : /Volumes/scanner/TEMP - BACK UPs/Source 1 AVIs MOVs/FOR LTO/6775_2.dv Format : DV Commercial name : DVCAM File size : 35.4 GiB Duration : 2 h 56 min Overall bit rate mode : Constant Overall bit rate : 28.8 Mb/s Video Format : DV Commercial name : DVCAM Duration : 2 h 56 min Bit rate mode : Constant Bit rate : 24.4 Mb/s Width : 720 pixels Height : 576 pixels Display aspect ratio : 4:3 Frame rate mode : Constant Frame rate : 25.000 FPS Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Bottom Field First Compression mode : Lossy Bits/(Pixel*Frame) : 2.357 Stream size : 30.1 GiB (85%) Audio ID : 0 Format : PCM Format settings : Big / Signed Duration : 2 h 56 min Bit rate mode : Constant Bit rate : 1 536 kb/s Channel(s) : 2 channels Sampling rate : 48.0 kHz Bit depth : 16 bits Stream size : 1.89 GiB (5%) _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
