Problem

[Ramparts]

Hi... I'm trying to use this great app but so far I can't... here is my problem: I used DVD Backup with the DVD I want to convert,,,then when I open it with ffmpegX for encoding if I:
1) choose Divx the encoding is done on a second leaving me with an .avi file with no info of course

2) choose VCD I get this error message:

Please help !!!

Please... I really really want to use this app...

I tried erasing it and re-installing... I even place the mencoder, mplayer and stuff on the same folder as ffmpegX , but I keep getting the same problem on both computers I have...

Heeeeeeeeeeeeeeelp...

Let's focus first on your first issue (encoding finished immediately). Click the blue "i" icon in the Progress window and post the process output, which could include relevant error messages.

This what I get:

You used the autocrop tool over a black image. Set a different "Start from:" point and autocrop again.

[Ramparts]

Ok thanx that's solved... set the "start from:" to 3 sec and started encoding correctly... that's for DivX

However, when I try to make the same VIDEO_TS to VCD I keep getting these error:

Maybe I'm missing something... isn't here a guide to VIDEO_TS to VCD or SVCD...?

Btw, thanx...

[major]

VIDEO_TS input is supported for CVD, SVCD and DVD conversion. VCD conversion does not support VIDEO_TS input - use VOB input instead.

[Ramparts]

Thanx for all your help major... now everything works...

One last question I encoded the VIDEO_TS folder into SVCD (2 cd's)...
I end up with (in this case) 6 .img files, I have to burn:

movie-1.mpg_01.img , movie-1.mpg_02_pregap.img , movie-1.mpg_02.img this three on one cd


movie-2.mpg_01.img , movie-2.mpg_02_pregap.img , movie-2.mpg_02.img and this three on another cd

right?

[Ramparts]

Ohhhh

I found another problem... I checked the the .mpg movies I get after the encoding... It turns out that audio and video are not synchronized... video and subtitles are but not audio...

Why is that...?

[major]

movie-1.mpg_01.img , movie-1.mpg_02_pregap.img , movie-1.mpg_02.img this three on one cd... and this three on another cd
right?

Almost.. replace "this three" by "this two", as you don't have to burn the pregap.img files.

This can happen with NTSC material. To avoid that problem, enable the "Decode with Quicktime" option. However, this will prevent you using VIDEO_TS folders. You can use 0SEx to obtain a VOB file instead of a VIDEO_TS folder. Also, in order to decode VOB with Quicktime you need to install the Apple mpeg-2 player component.
