VDub error message: "Invalid log file" (seems like a 1st pass problem)

[Tau]

Hi!

I am using VDub 1.4.10 with Gordian Knot and I am sometimes running into this crazy problem.

SITUATION:
I am basicaly following the GKnot guide at http://www.doom9.org/gknot-main3.htm. The final stepis to "Add Job to Encoding Queue" and start encoding.
The process sometimes(!) stops immediatelly with Virtual Dub's error window: name of the window: "Error" window text: "Invalid log file"
Gordian Knot log shows the sources of the problem: "1:06:17 PM: Error: Could not open I:\noaudio_1.log"
A complete GKnot log is attached.

ADDITIONAL INFORMATION:
Virtual Dub seems to have problems with the first pass. The log it sometimes creates doesn't look like a normal .log file:
##version 3
quality 5
bidirect 0
bidir_mult 2.000000
(yes, this was the whole "log" VDub creates in such situation)
Also, when I use GKnot's Compressibility Check (which uses VDub I believe), it lasts only a second and VDub barelly shows on my Windows98 taskbar at all.

Any idea what the problem is?
Thanks in advance for your kind answer :-)

Best regards,

Just try to reinstall the Divx Codec and hope it all works now

Thanks for the tip :-) but I have already done that several times and also tried different versions of Virtual Dub and Nandub etc. Those were the first things I have tested. Unfortunately, nothing worked :-(

Hello Tau or better Rich,

hm, I think the way of reinstalling the codec should work at least once, am I right ? After you have deleted the whole information of the last movie you created, the problem occures ? If that is right, then have a look at the details of divx5:
In VDub; Video -> Compression -> divx5...-> Configure -> Divx Codec Bar. What is the information at two pass encoding log files ? At your computer divx logfile is stored at "Harddisk\blabla..lastgknotmovie\...". Right ? Well then just choose select and search for "divx.log" directly at "c:" (no subdirectories) Do the same with the mvfile.
And now activate "protect MV/logfile" and hope it is really protected, I dont know exactly, but I had this strange problem and could fix it, if you get this error message again after some movies, just do it again.:scared:

Good Luck ;)

Hi!

Thanks for your time and tips :-) Unfortunatelly when using VDub thru GKnot, I cannot handle the DivX codec options directly. I have tested DVDx and it works fine and I get to manipulate DivX directly. Guess I will stick with that. Cannot spend years trying to figure out what's wrong. Anyway the problem is intriguing. I have just encoded a movie without a problem. Then I tried to encode other .VOBs on the disk and the described error showed up. When I try to encode .VOB that was ripped from a .VOB using VOBrator, the described error is back with vengeance ;-) I have written to the VDub author. If I learn what's wrong I'll try to write to GKnot authors to have the problem solution described in an official FAQ. No need for others to have the same problem. BTW have you seen the log created during the error (see above)? It seems like VDub starts the 1-st pass and then dies on the first frame. Wonder if there is the source of the problem? Guess I won;t solve it right now. If you or anybody else has any idea, I will be glad to test it. Would be nice to catch this bug :-)

Best,

Rich or Tau or... heck, who cares? People call me worse names ;-))

Hi Tau,

think your prob is exactly what i described above...did you try it ?

BTW: For GKnot ONLY use the Smartripper (in worst casaes vstrip) that is already included for ripping the vobs, otherwise you may also get probs...;)
