Help figuring out how to encode this old DVD
Hi,
I have a DVD I would like to backup properly encoded, below is the MediaInfo section relevant to the video. Could anyone tell me what processing I should do to it? I would like to use ffmpeg or handbrake (I'm on linux). Should I be using a deinterlace filter that changes the frame rate? I did some googling, and basically every thread contradicts itself. Here is a sample https://workupload.com/file/XShefM3kyXd Thank you! Video ID : 1 ID in the original source medium : 224 (0xE0) Format : MPEG Video Format version : Version 2 Format profile : Main@Main Format settings : CustomMatrix / BVOP Format settings, BVOP : Yes Format settings, Matrix : Custom Format settings, GOP : M=3, N=15 Format settings, picture structure : Frame Codec ID : V_MPEG2 Codec ID/Info : MPEG 1 or 2 Video Duration : 22 min 8 s Bit rate mode : Constant Bit rate : 8 000 kb/s Width : 720 pixels Height : 480 pixels Display aspect ratio : 4:3 Frame rate mode : Constant Frame rate : 29.970 (30000/1001) FPS Standard : NTSC Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Top Field First Compression mode : Lossy Bits/(Pixel*Frame) : 0.772 Time code of first frame : 10:00:07;11 Time code source : Group of pictures header GOP, Open/Closed : Closed Stream size : 1.24 GiB (98%) Language : English Default : No Forced : No Original source medium : DVD-Video |

Open it in a video player or editor which can play the video frame by frame.
Then you will see that there are 3 clean frames followed by 2 interlaced frames. That is typical behavior of a telecined video. Use Inverse Telecine to restore the video to 23.976. |
