I have a problem with encoding a video. So I have a video:
General > Format : MPEG-4 > Format profile : QuickTime > Codec ID : qt > File size : 306 MiB > Duration : 3mn 37s > Overall bit rate : 11.8 Mbps > Encoded date : UTC 2011-10-13 03:18:58 > Tagged date : UTC 2011-10-13 03:35:11 > Writing library : Apple QuickTime > Video > ID : 2 > Format : AVC > Format/Info : Advanced Video Codec > Format profile : Main@L4.0 > Format settings, CABAC : No > Format settings, ReFrames : 2 frames > Codec ID : avc1 > Codec ID/Info : Advanced Video Coding > Duration : 3mn 37s > Bit rate : 10.3 Mbps > Width : 1 888 pixels > Original width : 1 920 pixels > Height : 1 062 pixels > Original height : 1 080 pixels > Display aspect ratio : 16:9 > Frame rate mode : Constant > Frame rate : 25.000 fps > Color space : YUV > Chroma subsampling : 4:2:0 > Bit depth : 8 bits > Scan type : Progressive > Bits/(Pixel*Frame) : 0.205 > Stream size : 266 MiB (87%) > Language : English > Encoded date : UTC 2011-10-13 03:35:07 > Tagged date : UTC 2011-10-13 03:35:11 > Color primaries : BT.709 > Transfer characteristics : BT.709 > Matrix coefficients : BT.709 > Audio > ID : 1 > Format : PCM > Format settings, Endianness : Little > Format settings, Sign : Signed > Codec ID : sowt > Duration : 3mn 37s > Bit rate mode : Constant > Bit rate : 1 536 Kbps > Channel(s) : 2 channels > Channel positions : Front: L R > Sampling rate : 48.0 KHz > Bit depth : 16 bits > Stream size : 39.8 MiB (13%) > Language : English > Encoded date : UTC 2011-10-13 03:35:07 > Tagged date : UTC 2011-10-13 03:35:11 I want to convert it to .ogg file and preserve its: audio/video parameters like bit rate aspect ratio and amount of pixels, but when I try to encode it with ffmpeg it always lowers audio/video bit rate. can you tell me a commend that will output a similar file like the source is Thank you in advanced
