I have an MPEG2 video ES file created by demuxing an NTSC DVD. Some of the frames in it are the result of telecining, but I don't care about that - at this point, I want to treat it as 29.97fps progressive. I'm pretty sure that none of this file is soft-telecine (with 23.976 fps stored in the stream and the DVD player expected to perform the pulldown to generate 29.970). It seems to be a mixture of 29.970 progressive and 29.970 hard telecine. However, I'm not certain of that; I haven't found a good way of testing it.
When I try to load the file in Cinelerra, it takes up about 610 seconds on the timeline. That's both if I read the .m2v directly or if I pre-generate a .toc file with mpeg3toc. But all the other software I have that can read .m2v files (namely, transcode and mplayer) report it as being 586 seconds in length. Cinelerra reads it as about 4% longer than the other software. This creates problems because I'm using transcode and custom software to create a visual index of my footage which I'll then use while editing with Cinelerra; I need the frame counts to be the same between the two. When I ripped the DVDs I discarded the audio track because I didn't need it, but I plan to go back and re-rip the audio from this chapter so I can verify its length; that may give me some clue as to how long the video is actually supposed to be. At this point, though, it looks like Cinelerra's MPEG reader is counting frames incorrectly. Is there anything I can do about it? -- Matthew Skala [EMAIL PROTECTED] Embrace and defend. http://ansuz.sooke.bc.ca/ _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
