A variation of mencoder dvd://1 -o outfile.avi -oac pcm -ovc lavc -lavcopts vcodec=mjpeg:vqmin=1 will create an avi file with pcm sound and MJPEG video. Bear in mind that this conversion, as the subsequent conversion back to MPEG2 for the DVD, will degrade the quality for each step. It would be beneficial if you could use gopchop or a similar MPEG2 cutting tool instead.

[Mjpeg-users] mjpegtools, qdvdauthor to make DVD
Hi everyone, I'm finally getting around to trying to make some DVD's from older VHS tapes. After getting a Canopus ADVC-110 and LOTS of emails to Steven Schultz, I'm getting there. Thanks a lot for all the help Steven. I'm still unsure how to make a DVD (with the menus and so forth) if I process the raw capture files via a script like this: smil2yuv -i 2 -a video.mp2 video.smil | y4mshift -b 8,0,704,476 | yuvdenoise -s 4,5,5 -g 64,255,255 -t 3,4,4 | y4mscaler -v 0 -I active=704x480+8+0 -O sar=src -O chromass=420_mpeg2 | mpeg2enc -f 8 -D 10 -E -10 -4 1 -2 1 -c --dualprime-mpeg2 -q 8 -o video.m2v It looks to me like Kino and qdvdauthor are designed more to take the raw capture files and process them based on the various settings within that particular program. Is this the case? If so, is there another way to generate the XML file (manually create) so qdvdauthor will see it as a project file if another script (like the one above) is used? Or is there another way to do this that I'm unaware of? It takes an awfully long time to process the capture files into a mpeg2 file. Like 3 hr and 20 minutes or so for 30 minutes of video. That's on a machine with FC4, a 2.8 Ghz Celeron, 1 Gb of memory and a 120 Gb 7200 RPM Deskstar. I'm hoping I don't have to go through it all over again. Thanks for any and all help.

Coming from a DVD I really do not think square pixels (-a 1:1) is the proper setting. If it's a non-widescreen NTSC then 10:11 is the value, widescreen NTSC is 40:33. http://www.mir.com/DMG/aspect.html is a good place to bookmark ;) Even for testing I think it's a good idea to use the correct aspect values. But when i do a lavplay later on test.mov i get: Unable to identify file (not a supported format - avi, quicktime). That is to be expected since Y4M data is neither avi or quicktime. Simply putting a .mov in a filename doesn't cause a transformation from Y4M data to a Quicktime wrapper. So i am not sure if pgmtoy4m can store the output in a file which i can use with glav/lavplay etc... as the stuff in the manpage doesn't I guess I read too quickly thru the goal you're trying to achieve. I (mistakenly) thought you were simply trying to recode a DVD to a different format. Also the audio won't be available here, so i guess ffmpeg or mencoder will be better here to have the audio too. Extract the audio to a separate file. Any decent editor will have the ability to import the video and audio from different files. Editing MPEG-2 video can be done one of three ways: 1. Edit with GOP sized resolution (typical DVDs are about 15 per GOP or about .5 seconds) with something like ProjectX http://www.lucike.info/ - then export new files (audio and video) which can be mplex'd together. 2. A lossless decode to uncompressed Y'CbCr, do the editing, export the data to a new uncompressed file and encode. There will be some loss of quality due to the re-encoding but it's not too bad. 3. Decode the original MPEG-2/VOB file, do a lossy encode to something glav understands (MJPEG or DV), edit, decode the MJPEG or DV, encode to MPEG-2. If you encode to DV25 then Kino could be used to do the editing. I've seen the results of going thru an intermediate lossy compression step and it's not pretty ;( For #2 perhaps Cinelerra can handle uncompressed video. The couple times I've done this type of thing I supersampled the chroma from 4:2:0 to 4:2:2 (using y4mscaler) and created a '2vuy' (uncompressed 4:2:2) Quicktime file from the Y4M data (using a hack written for the purpose). Editing and rendering was done using Final Cut Pro. BTW i might recompile the mjpegtools here as i get Segmentation fault very often. Either i recompile version 1.8.0 or get back to 1.6.2. Can't fix what hasn't been reported. We're not mind-readers ;) A better bug report than I get segmentation fault very often would be a good start :-) Knowing what program(s) were crashing would also be useful information. I haven't had an segment faults in the encoder or multiplexor (mpeg2enc or mplex). There is a memory leak in the Quicktime audio handling - if you're seeing crashes due to memory allocation there's a small patch in the recent mailinglist archives. It's been fixed in CVS of course ;) Cheers, Steven Schultz --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl ___ Mjpeg-users mailing list Mjpeg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mjpeg-users

The bottleneck is not the encoder but the other processing - denoising/enhancing/etc video is time consuming. with FC4, a 2.8 Ghz Celeron, 1 Gb of memory and a 120 Gb 7200 RPM Celeron does have a smaller cache - that might be a small part of the slowness. But with 5 process in the pipeline there's a lot of competition for 1 cpu. Deskstar. I'm hoping I don't have to go through it all over again. No, once you have the .m2v and .mp2 (or .ac3) files then you 'mplex -f 8 -o output.mpg input.m2v input.mp2' and send the output.mpg off to the dvd authoring process. The other DVD authoring programs I'm familiar with use the elementary files (.m2v, .mp2) and do the mplex'ing as part of the final output processing (when the .VOB files are being created).
