While I am waiting for Transcode to get fixed, I am experimenting with other ways of getting my home movies to DVD. I have listed the steps below and am curious if my current end result will improve with the use of Transcode for encoding? This is nothing more than a bunch steps that I have gathered from various sites. I have no idea if this is a good way to get the job done or not. Some processes talk about creating an iso file before burning it out to dvd. I am unclear on why that might be needed?
1. I use Kino to pull in the video from my camcorder
2. I use avimerge to create one large avi file
3. lav2wav +p myfile.avi | mp2enc -V -o audio.mp2
4. lav2yuv +p myfile.avi | mpeg2enc -n n -f 8 -s -r 16 -o video.mlv
5. mplex -f 8 audio.mp2 video.mlv -o endresult.mpg
6. dvdauthor -o finalproduct endresult.mpg
7. dvdauthor -o finalproduct -T
8. Test it out with xine
9. growisofs to burn it to DVD.
My end result is a pretty clear DVD, but I think it could be better. I have only attempted this using Linux and have no plans to go the Wiindows route, although I have seen some pretty good output from people who have used TMPGenc for their encoding.
All feedback is welcome.
Thank You

Have you tried playing with enforcing the aspect ratios ?
4:3 would be a good start.  |
ok how the hell do you do that
i've read the manpage and according to it using the normal size with -Z (the standard PAL size) and the --keep_asr option it will make the video have black bars top and bottom in order to keep aspect ratio. so i'm using this:
| Code: |
transcode -i Film\ -\ Ghost\ In\ The\ Shell.avi -V -Z 720x576 --keep_asr -y mpeg -F d,1 -E 48000 -b 224 -o gits
|
the way the manpage explains it working is like this:
| Code: |
--keep_asr
try to keep aspect ratio (only with -Z) [off]
The --keep_asr options changes the meaning of -Z. It tries to fit the video into a framesize specified by -Z by
keeping the original aspect ratio.
/------------------------\ /---480-------\
| | | black |
|720x306 = 2.35:1| -> -Z 480x480 --keep_asr -> |-----------------4
| | | 480x204 8
\------------------------/ |-----------------0
| black |
\-----------------/
Consider --keep_asr a wrapper for calculating -Y options and -Z options
|
however it does not work, the video is streched still on normal playback instead of being a rectangular shape
also the in the notes i tried the enforcing 4:3 and still nothing changed |

Try to give transcode the asr you want to get in the end. Usually it should autodetect and use the right ASR, but I've discovered that it doesn't work sometimes or that I misunderstand the concept. 
Add --import_asr X and --export_asr Y to the --keep_asr option. For example 16:9 to 4:3 (adding black borders at the top and bottom):
| Code: |
transcode -i Film\ -\ Ghost\ In\ The\ Shell.avi -V -Z 720x576 --keep_asr -y mpeg -F d,1 -E 48000 -b 224 -o gits --import_asr 3 --export_asr 2
|
Maybe this helps? |

Having a spot of bother with some transcoding, I wonder if anyone knows what's up here...
I transcoded the Simpon's THX spoof without any problems, using shiznix's original command-line. The mplex'd audio & video stream plays fine in mplayer and xine.
Now I'm trying to transcode a MPEG PES stream - recorded as an MPEG transport stream from a DVB card, and converted to program stream with the ts2ps utility (part of dvbtools). Both the raw TS stream and the PS stream play fine in mplayer and xine.
However, when I transcode as follows:
| Code: | transcode -i input.mpg -M 0 -y mpeg -F d,1 -E 48000 -b 224 -o test1
mplex -o test1.mpg test1.mpa test.m2v
|
The resulting movie is just a blank screen, in mplayer and xine. The audio is fine, but no picture. I don't get any errors during transcoding - at least, nothing that seems fatal to my untrained eye:
| Code: | $ transcode -i input.mpg -M 0 -y mpeg -F d,1 -E 48000 -b 224 -o test1

Anyone know what's going on here? Thanks!
Update: so the "import format MPEG-2 (V=null)" doesn't look good, nor does "import frame | disabled". Looking on the transcode mailing lists, there was a similar question in 2002 about this, but no final answer. I've retried with "-x mpeg2,mp3" option to transcode, but no luck - still a blank video.
I've also tried converting to AVI with mencoder (I noticed the "-oac lavc" option doesn't work, so I used "-oac copy"). mencoder segfaulted on this after creating a partial AVI - this AVI plays OK in mplayer too, but immediately crashes transcode. Ho hum.
I'd be interested to know if anyone at all has had success in transcoding program streams...

don't you worry, wine people have done a good job. TMPGEnc works with wine out of box...I have encoded my DV footage with it. |

Just a blind shot on my side here... try to use "-x mpeg3" Transcode will try to use libmpeg3 (must be installed, it's not part of transcode) to decode the MPEG2 stream.
See ya,

Nice read!
A question, how can I add a sub or srt file as subtitles to the DVD?

Hi desh,
James Tappin's Howto at -> http://www.tappin.me.uk/Linux/dvd.html
is based on encoding/burning DVB to DVD, though he uses a camcorder & not a capture card, both are DVB devices & so should still be relevant (uses Kino).
Note that I don't own any DVB devices to test this  |

Well, "-x mpeg3" doesn't help either - still just a blank video. James Tappin's guide doesn't tell me much either, unfortunately - it doesn't seem very relevant to DVB.
I'll probably have a play with avidemux and/or kino next and see if I can export anything useful from there... thanks for the pointers though, guys.

I finally got around to getting some screenshots of the funky colors (the red streaks through the picture):
http://www.odc.net/~ssharma/curb1.png
http://www.odc.net/~ssharma/curb2.png
I haven't tried burning a dvd yet but is that green bar at the bottom normal? This is for an NTSC disc, by accident I encoded a PAL version and the green bar wasn't there...
thanks,
ajay
PS. oh and mplayer always crashes when I try to play the final mpg file (right before I use dvdauthor). I can only preview the file with xine which is strange since mplayer *rarely* crashes. |

That strange colors happen to me, i have to adjust the video almost manually, I read somewhere (maybe this thread) that is a problem with the resizing .. but I'm a newbie so..
I did it this way :
| Code: | | transcode -i video.avi -V -y mpeg,mp2enc -F d,0 -E 48000 -b 224 -o video -m audio -Y -80,0 -Z 720 --export_asr 3 |
And it works.. just start transcoding and in another console watch the video output to see that is correct, if not play with the -Y and -Z values..
-----------
About the subtitles I don't see a fast solution, because the link provided up there is for subtitles in pgm format, the original dvd format, and not the SUBRIP format, and to convert it you have to:
1- Create a PNG image for each subtitle line
2- Create and XML file with the timing of that image.
Is needed someone with high scripting skill (not me) |

I have had exactly the same problem as you. Temporarily solved by downgrading to version 0.6.10.
| Code: | | emerge /usr/portage/media-video/transcode/transcode-0.6.10.ebuild |
Hope that helps... |

VAMPS is a fast requantizer for ripping streams from a DVD and compressing them ready for further use with DVDauthor.
Get it here:
ftp://ftp.heise.de/pub/ct/listings/0401-094.tgz
Sample usage:
Rip the stream Track 1 Chap 1 angle 1:
#vamps-play_title /dev/dvd 1 1 1 > chapter01.mpg
Compressing the Stream using audio channels 1+2, subchannel 3 with factor 1.5
# vamps -E 1.5 -a 1,2 -s 3 < chapter01.mpg > c_chapter01.mpg

Quick hint:
The LATEST transcode - v0.6.12 supports a simplified command ling for dvd mpeg encoding:
| Code: | XXX@XXX$ transcode -i <I/P_F_NAME> -V --export_prof dvd-pal -o <O/P_F_NAME>
|
In the above command 'dvd-pal' can be replaced with any one of:
vcd, vcd-pal, vcd-ntsc, svcd, svcd-pal, svcd-ntsc, dvd, dvd-pal and dvd-ntsc
This sets all the required options and converts to the format you request. I believe it also sorts out the aspect ratios for you...
See: http://zebra.fh-weingarten.de/~transcode/man1/transcode.1.html for more info.
Incase anyone is as new to this as me then to get this version I:
1)Copied the ebuild file:
'/usr/portage/media-video/transcode/transcode-0.6.11.ebuild'
to
'/usr/local/portage/media-video/transcode/transcode-0.6.12.ebuild'
then, making sure the PORTAGE_OVERLAY line is uncommented in /etc/make.conf, typed:
| Code: | | XXX@XXX $ ebuild /usr/local/portage/media-video/transcode/transcode-0.6.12.ebuild digest |
Then:
| Code: | | XXX@XXX $ emerge transcode |
This failed onece, with a message about mmx support patch not veing available. To solve this I comment out the line that tries to patch the source tar.gz in the ebuild file.
| Code: | | # epatch ${FILESDIR}/${P}-no-mmx.patch |
This makes life easier for me so I guess it may for someone else.[/url] |

Hi pzasso,
I too got the same problems that you experienced with transcode, I ran an emerge -vp transcode and noticed it wasn't using mmx or sse. After adding mmx and sse to my use flags (I was sure I did this when I first configured my system?), transcode runs fine.
I hope this helps

|
|
| Does anyone know why dvdauthor would not make a VIDEO_TS.IFO. It finishes turning the mpgs into vobs (3 titles, one titleset) and makes the VTS_01_0.IFO and .BUP. Then it says that is is making table of contents but gives an error message "No .IFO files to process" or something to that effect. Does anyone have experience with this? Thanks |

hey, cool to have found this thread, as i had no luck to install MyDVD with crossoveroffice/wine...
but i got problems generating the menus. when i follow the first post, ia always get a blank screen when i play the dvd, except the *highlighted* part, which is visible. i do hear my sound. in xine, i can click on any part of the screen and it will start the *first* movie. no chance to start the second. further investigation revealed, that spumux always recognized *one* subtitle, which in fact is the whole image. i tried to manually write the places of the buttons into spumux.xml, but i didn't get it, i always get errors, because i don't really understand the syntx. manpage doesn't help a lot. if anyone has a sample spumux.xml file with manually defined buttons or could point me into a direction why spumus recognizes the whole screen as a button, i'd be very happy.

|
|
| Well, my problem with the generation of VIDEO_TS.IFO was solved by the realization of a very annoying fact. My DVD was being made on a FAT32 partition (only drive with the space left) and was mixing up the case sensitivity. Dvdauthor was expecting VTS_01_0.IFO and was getting vts_01_0.ifo but FAT32 doesn't note any difference between the two. It was solved by putting the .IFO file in a empty dvd structure on a more modern file system (reiserfs) and running dvdauthor -o directory_here -T , then transfering the resulting files back to the FAT32 partition. This should not be a common problem but I thought that I would explain just in case. |

Came across a video last night that when encoded, had the same diagonal red streaks running through it that Viperlin & ajayrock mentioned.
The problem lies with transcode's internal mpeg encoder not encoding properly on some DivX.
The solution is to tell transcode to use the external mpeg2enc program to encode, like this: | Code: | | transcode -V -i <input_file> -y mpeg2enc,mp2enc -F4,"-n p -f 8" -b 224 -E 48000 -o <output_name> |
Howto updated to reflect this, see there for more detail.
Thanx  |

This command line is much nicer however, a couple of points:
- The '-E 48000 -b 224' audio part is still necessary to get a DVD compliant audio stream.
- The encoding is much slower. About 5 times slower than
| Code: | | transcode -i matrix.mpg -V -y mpeg -F d,1 -E 48000 -b 224 -o matrix |
Although this sometimes produces strange colour streaks.
And about half as slow as | Code: | | transcode -V -i matrix.mpg -y mpeg2enc,mp2enc --export_asr 2 -F4,"-n p -f 8" -b 224 -E 48000 -o matrix |
Which usually always works.
Latest transcode 0.6.12 is in portage, there's also been an update to mjpegtools (1.6.1.92)
Cheers,

I'm baffled as to what it could be. You might try the dvdauthor mailing list here -> http://lists.sourceforge.net/lists/listinfo/dvdauthor-users
Be sure to include the spumux.xml file you're using when/if you post there. |

Thanks for the response.
But in the meantime i found out what i was doing wrong. I used your sample pictures and realized that i didn't choose "transpaency" for the menu_highlight and menu_select but used "background" when i created the new layers.
Now it works like a charm
Thanks for your cool guide!

ok is there any special "speed up" option? i just ask because whenever i encode a video file (the same file actually) it goes at different speeds, same command. like at this very moment i was going to encode a film and watch it, but it's going at 17fps.
last time i did this it was going at 43fps
it just seems completely random to me. same things running and everything, same conditions. |
