 Posted: Mon Nov 29, 2004 9:06 am Post subject: Converting variable FrameRate DivX 2 somethin (Mpg) burnable |
 |
|
Greetings,
Ive had my family overseas upload a 500MB DivX 5 Variable-Frame Rate "family video".
Basically I want to convert it into something else, such as an mpeg so that I can eventually burn it to DVD using the following:
| Code: | josiah@Stellar josiah $ cat Docs/Dvd_Creation
Pal:
transcode -i matrix.mpg -V -y mpeg -F d -Z 352x288 --export_fps 25 --export_asr 2 -E 48000 -b 224 -o matrix
Ntsc:
transcode -i matrix.mpg -V -y mpeg -F d -Z 352x240 --export_fps 29.97 --export_asr 2 -E 48000 -b 224 -o matrix
mplex -f 8 -o matrix_dvd.mpg matrix.m2v matrix.mpa
dvdauthor -o finalproduct endresult.mpg
dvdauthor -o finalproduct -T |
This was taken from:
https://forums.gentoo.org/viewtopic.php?t=117709
This however doesnt seem to work with the way my family have encoded this DivX.
Basically the Audio/Video are always out of sync, regardless of using mplayer to pipe it to transcode etc 
Any ideas?
Many thanks
Chill. |

Hi 
Unfortunatelly I'm not much of a command-line interface expert but if you would consider using a GUI you could try media-video/avidemux...
There's nice forums:
http://avidemux.berlios.de/forum/
The author and users are very friendly and I'm sure I could gets some help.
Maybe this little tutorial on creating a xVCD / xSVCD, I've written, could be helpful to you (scroll a bit down):

Good luck

Thanks - I try that but it looks incredibly jerky
So far the output is:
Jerky video and in-sync sound/audio
Or:
Smooth video thats marginally too fast so doesnt match up with
Any other ideas?
Thanks

Hi
Are you talking playback in avidemux or about the resulting file?
If it's the first thing than you needn't worry - it's "normal" and absolutely doesn't affect the result.
If it's the latter than you could try asking in the avidemux forums...
To see what the result will be like you can just encode for example a couple of minutes (if you haven't done that already).

What format is the movie in now? I'm just curious because AVI doesn't technically support variable frame rate video. Do you know why they chose an esoteric standard, the only real USE for something like that is cell animation. If you are using an intermediate file format, make sure to save it in matroska or some other container format that supports variable frame rate.
You might want to take a look around http://forum.doom9.org/ they have about the best AV info I've seen. Most of it is Windows-centric, but a lot of the techniques can be applied elsewhere. There is also a fairly small Linux only forum there too... |

No, its definately jerky as an output file... I dont bother with the internal preview mostly.
What filters/outputs would you recommend?
I origionally got the file playing on the Family's PC - I opened it in WinAmp and it varies between 24fps and 30.5fps! They sent me this:
http://www.dimension.net.nz/dump/make1.avi
This was a small >2MB file made encoding using Dr DivX in exactly the same way.
Re-encode it using either of the previous ones and its outa sync horribly |
