2003-01-25 Thread Matti Haveri
The following site has a MPEG2 encoder comparison (Apple's QT Encoder, BitVice, Cleaner 6, Digital Media Press, Media Pipe (mpeg2enc as its engine), Media Press Pro, ProCoder and TMPGEnc). The first three places were taken by TMPGEnc, ProCoder and Digital Media Press. mpeg2enc did rather well,

Hello, I have used the mjpegtools for months in order to create mostly SVCDs. The only source I have are mpeg2 stream. Sometimes DVDs, but most of the time mpegs that I stream from my digital satellite reciever directly to my harddisk. So far I didn't have many problems. (except for NTSC DVD's wh

Can anyone point me at a source of information on calculating bitrates for transcoding to svcd with mjpeg tools. Or even a calculator that runs under linux. At present I transcode my captured video with a best guess bitrate and then modify the bitrate accordingly to fit it on 1 or more 80 min
