Re: [CinCV] Howto produce HD mpg 1080 from Cinelerra
Ed, I had a similar problem getting the output from my Canon 5D Mark II into a Cinelerra-usable format. My solution was to reencode the 1080P H264 into 1080P MPEG-TS. Here is my tale of woe from earlier this year: http://crazedmuleproductions.blogspot.com/2009/02/dark-of-winter-has-me-in-its-grasp.html The MPEG2-TS is the section you'd want to focus on. scott http://crazedmuleproductions.blogspot.com Hello Scott, Thanks for the information. I see that you had to recode a .mov file to make it acceptable to Cinelerra. You also say that the mjpeg does not live up to quality standards and I think you are right. Besides, I would like to offer footage to Cinelerra that has not been recoded so that the original recording quality is maintained. That is possible because the .tod files that my JVC GZ-HD30 produces are in fact mpeg2 files. When feeding the .tod to avidemux, it is recognize as a MPEG TS. As said in a previous message, I used ffmpeg to convert the .tod file to mpg as Cinelerra accepts it, while avoiding encoding by copying the codecs: fmpeg -i footage.tod -acodec copy -vcodec copy footage.mpg The drawback is the fact that when imported in the Cinelerra timeline, the video part is a few frames longer than the audio part at the end due to the fact that the tail of the audio is apparantly cut. So it is not a synchronization problem. When importing the file footage.mpg to MainActor, everything is all right: video and audio are equally long. So it is not a problem of footage.mpg itself but the way Cinelera looks at it or the way the timeline presents this particular mpeg footage. I am going to experiment a bit more.

Hello Simeon, That is certainly a good idea. But first I try to experiment a bit to see if I can still feed the orginal footage to Cinelerra, so without any re-encoding.

Re: [CinCV] Howto produce HD mpg 1080 from Cinelerra
Succes at last, though my workflow is far from elegant. Convert the .tod files from my JVC GZ-HD30 camcorder with avidemux: export with video as MJPEG and audio as WAV, format AVI. This will make all clips, when imported in Cinelerra, have video and audio matching exactly in length. After editing in Cinelerra, export as advised by Simeon: To export the video through YUV4MPEG Stream use the following pipe command: ffmpeg -f yuv4mpegpipe -i - -y -r 25 -b 2800 -f mpeg2video % As Cinelerra Format settings i would suggest a frame rate 25. fps and 1920x1080 as size of your canvas. Export your audio as MPEG Audio, select Layer II and 384 kbit/s. Next, the muxing must be done using avidemux again: first importing the .m2v and adding the audio file using the Audio-main track-external MP3 Export with video and audio set to copy and format MPEG TS (A+V). This will result in an mpg file that will play both in mplayer and on my networked media tank HDX1000. ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

Re: [CinCV] Howto produce HD mpg 1080 from Cinelerra
Hello Simeon, That works. Much better than using the pipe with mpeg2enc, which always resulted in errors, no matter what settings I used in the format as well as the parameters passed to mpeg2enc. I have been busy in the mean time and found that exporting to mov or mkv or avi, using a variety of codecs, and then using ffmpeg to convert the result to mpg also does the trick. But in all cases (also when I follow your advise) something strange happens: when playing the movie, there is a little pause whem the border between two scenes is crossed. You see, for purpose of testing, I used 5 pieces of footage in the timeline, one after another and no gaps in between.So there are 4 places where a new scene starts and always this little pause occurs when passing this border, a pause that last no longer than a fraction of a second but is still very noticable. Is this typical for mpeg footage?

Simeon ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra Hello Simeon, I think I will have to check again a few things. There could have been gaps between the footages. In the meantime, I followed an alternative approach. I used avidemux to convert the .tod files to MJPEG-files with WAV as audio. These files I carefully aligned next to eachother in the Cinelerra timeline and I then produced the .m2v and the .mp3 file, following your advise. Yes, mp3 instead of mp2, as this was the default.

Simeon ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra Talking about gaps. I think that they may have been there, due to insufficient alignment by me in the timeline. But while investigating this matter, I found something else. When placing the mpg-files in the timeline, I mean the files produced from the original footage with the command: ffmpeg -i movie.tod -vcodec copy -acodec copy movie.mpg I found that the audio part was slightly shorter\d than the video part. Perhaps only 1 or 2 percent. Sigh After all these years, the conversion wizards still manage to screw this up. After 20 years of programming, they still cannot align video and audio. ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
[CinCV] Howto produce HD mpg 1080 from Cinelerra
Hello, I purchased a HD camcoder (JVC GZ-HD30) that can record both in AVCHD and MPEG2-TS in 1920x1080i. I used it during my holidays and recorded in MPEG2-TS. The files all have extension .tod, that must be converted to mpg with ffmpeg to make Cinelerra willing to import them: ffmpeg -i movie.tod -vcodec copy -acodec copy movie.mpg Using tcprobe gives the following information about the converted file: $ tcprobe -i movie.mpg [tcprobe] MPEG program stream (PS) [tcprobe] summary for movie.mpg, (*) = not default, 0 = not detected import frame size: -g 1920x1088 [720x576] (*) aspect ratio: 16:9 (*) frame rate: -f 25.000 [25.000] frc=3 PTS=12382.5579, frame_time=40 ms, bitrate=28000 kbps audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x50 [0x2000] (*) bitrate=384 kbps Funny enough it has 1088 lines instead of 1080. Anyway, this file, slightly smaller in size than tye original .tod file, I can play flawlessly on my media player HDX1000. So I would like now Cinelerra to produce that kind of file after editing and that is where the problem starts: I tried some containers and formats and codecs when rendering but the result did not play on the HDX1000 or only with an annoying amount of stuttering. Yet the HDX1000 is able to play quite some formats and codecs. Cinelerra also does not seem to have a format that produces 1920x1080p with frame rate 25. Do I have to export to quicktime for linux, for example with Compression Component Y'CbCr 8-bit 4:2:2 (yuv2) and then use ffmpeg to produce the kind of file I want? Please some advice.
