[Mjpeg-users] mpeg2enc options

2003-11-26 Thread Florin Andrei
Conditions: My source is a cheap CCD, not too bad, pretty good detail, excellent chroma, some mild noise when in the dark but otherwise it's clean. The camera is amateurishly handled: quiet scenes interrupted by bursts of brutal motion. It stores the image in NTSC 480i DV format. I capture it with

[Mjpeg-users] -H and -E

2003-11-26 Thread Florin Andrei
I'm not sure i understand how -E works, so... Is there any conflict if i use -H and -E simultaneously? If not, does it make sense from a logical p.o.v. to use them both? Does -H override -K, or the other way 'round? -- Florin Andrei http://florin.myip.org/

Hi Andrei, If i understand correctly, one of the reasons why mplex cannot multiplex subtitles was the scarcity of tools to generate subtitle streams with timestamp information. Thanks for the info - adding subtitle muxing itself once you can get the timing info is pretty easy. It is quite
