Transcoding mpeg2 video to dv
I just bought a video camera that uses a dvd to record the video. Now I am trying to transcode the video (in vob format, aka mpeg2) to dv so that I can edit it with kino. I have tried transcode, ffmpeg, dvdrip and acidrip with little success. Now I am wishing that I would have bought a DV type recorder.
I figure transcode is my best bet as it has lots of features. I am a newbie to video, and have been reading up on it the last few days. I've been over the transcode manual pages more times than I can count. The program finishes with no errors, but the video looks very strange. Sound seems OK. There is one row at the top with two windows showing the video, under that are two rows of four windows showing the video and the bottom row has black/white inverted. All the way across the bottom is a green/black box. The color in all windows is kind of green tinted and looks mostly black and white. Here is the command line that I am using for transcode: Code:
transcode -i vts_01_4.vob -A -I 1 -M 2 -N 0x2000 -Q 5,5 -f 4 -w 2400,250,100 -x vob,ac3 -y dv -export_fps 24 -o test.dv Code:
transcode v0.6.14 (C) 2001-2003 Thomas Oestreich, 2003-2004 T. Bitterberg Code:

Anybody there???
I figured out a way to get it done. I'm using lives to edit the video and qdvdauthor to create the dvds. Lives will import the vob files automatically. It takes a long time probably because it is transcoding into some other format. But other than that, everything is OK. The finished video looks good. |
Found some other usefull stuff to get the job done. Avidemux seems like it may be better than lives for splitting and/or merging video segments since it operates on the original video without any transformation until you save it. You can also save it without transformation. So it is possible to cut and paste without having to encode; however, when I tried this there was a small disruption at the cut points. Encoding into mpeg2-dvd got rid of the digital hiccup at the cut points.
When you load a video in lives it transforms every frame into a jpeg (or png). You then edit these and then encode the results in the desired format. That's two steps where loss can occur. I haven't played with it enough to know if the degradation is even noticable. Probably depends on the amount of motion in the video. Cinelerra also looks cool if not very complicated. I don't think my pc has enough horsepower to run it though. |
Hi!
Your original post.. If there is a way to get the video from your camera to your computer instead of using the DVD as the interface, I'm thinking via firewire, you can grab it as a dv file using dvgrab. THEN kino can edit that file directly... You can also skip the dvgrab part and use kino (which uses dvgrab) to grab the video from the camera. This is just a thought, not sure if your camera has this feature or not. Cool |
That's how it works for DV based cameras. My camera records directly onto CD in mpeg2 fomat (not DV).
