Can not write log file

[Dreamweaver]

HI!

I'm having the following problem:
When I try to do a compressibility check, virtual dub pops up for about a second and then it say's check finished, but in the LastCompressibilityCheck.log it say the following:

21:48:12: Started DivX5-First Pass: D:\DVDrip\GORDIA~1\LastCompCheck.avs
21:48:22: Finished DivX5-First Pass. Duration: 10 seconds.
21:48:22: Trying to open Log-file.
21:48:22: Error: Could not open E:\dvdrip\starwars_5_perc_D5_NeutralBicubic_534x224.log
21:48:22: Error: Could not count encoded Frames.
21:48:22: Speed: 0.000 Frames per Second.

The directory is not write protected or anything. And When I try to encode the movie otherwise it's the same thing. A message comes up, that the movie could not be written and that's it.


Any ideas?

Post the .avs and we'll see what we can do. First thing to check is usually that you have all even numbers in the crop though.

You mean LastCompCheck.avs?
Here it is:

First thing to check is usually that you have all even numbers in the crop though.

I tried it again. Now the resize is 532,224,0.05 not as before 534,224,0.05. Now it seems to work. But 534 seems as even to me as 532, or am i wrong?

The filename of the .d2v is starwars so I assume this is film content, and in that case you should not need de-interlacing. besides, as you are trying to feed a 439 lines high clip to verticalreduceby2, how many lines would you say you get left? :devil: Just teasing, you need (like I said in my last post) an even number of lines in order to make verticalreduceby2 work.
My suggestion is: Skip de-interlacing. If it doesn't look good, you probably need IVTC if you have NTSC or telecide() (alone) if you have PAL.

[hakko504]

No problem with the resize, but the crop should be crop(0,70,718,436)

[Dreamweaver]

hey, I just trusted the auto crop button.
Well, well... as my mother always said never trust a machine! :D
Besides, why did it work the second time I tried?
The only thing that I'm aware of changing was the resize to 532 instead of 534. At least the .avs is the same.

Hi-

Is this DivX 5.02? Horizontal resolution must be a multiple of 4. However, I find neither 532 nor 534 acceptable. I'm sure GKnot didn't give you that resolution, unless you changed the W-module. Default is 32 for a reason.

[Dreamweaver]

jep it was the W-Module!
must have chanced it by accident.

You're kinda smart man, huh? :D

THX alot

Better stick with W:32 H:16 (or at least don't go below 8) - even if your graphics adapter now is able to play some weird resolutions correctly on full screen, you might experience bad surprises on other computers or when you next update your graphics adapter (or drivers).

btw. divx compresses better when H and W are divisible by 8 (because of the block-size)

[Dreamweaver]

So why is there a range from 2 to 32 at all? If it has to be a multiple of 8, why not just make it 8 fixed, anyway? Why 32 W and 32H or 32W and 16H, at all?

[theReal]

I don't know what's it with the 32 and 16. However, 32 and 16 are multiples of 8 and it seems that W:32 H:16 has been a kind of standard for computer video, so any graphics adapter can deal with it.

Not long ago I had a Leadtek Winfast Geforce 2MX that wasn't capable of displaying W:32 H:8 encoded videos correctly while my much older Matrox Millenium G200 could even display W:2 H:1 (I'm talking about fullscreen - 100% size is never a problem).

I think a warning in Gknot about all that would be ok (I also started out setting it to W:8 H:4 and now have some videos encoded like that)
