Need help with error message "Skipping chained jobs"

[Vesi]

I get this error when i want to change my xvid or x264 encoding type to 2pass-2ndpass and for x264 to 3pass-3rdpass.

Like today i tried encod with xvid 2pass-2ndpass and i got this error

That would be what happens when you try to run a second or third pass without first running the first pass. Did you queue up one of those first?

this happened when i chose 2pass-2nd pass. And then i thought that maybe that is not the right way to do 2pass, i restart megui open my file calculate the bitrate and went to config to change it to 1st pass-2nd pass and Queue and back to config to change it to 2pass-2nd pass and Queue and start encoding, and when the 1st pass came to 98% i got xvid_encrow crashed. and got this

Then I tried for automated 2pass and same error came again.
Am i doing something wrong with 2paas-2nd pass or 3pass-3rd pass?
if i am wrong please guide me how to do it.
the reason i am doing 2pass, i want to tweak Overflow treatment values.

Edit: I got the same problem with x264

This is the first time i get this kind of error after using megui for almost over a year.

Your avisynth installation is broken somehow. Delete the avisynth and megui folders, download megui.exe, switch update to development server, and run an update to reset everything. (There are other ways to do this, but you'd probably just get frustrated trying to do them.)

Use automated 2 or 3 pass if you don't have any good reason to use manual passes, also. You can tweak overflow values with automated too, or if you really want to run repeated second passes without repeating the first, you must run a manual first pass (stats get deleted after automatic).

thanks foxyshadis, now everything work fine, I'm doing 2paas-2nd pass because i have read in Oversized/Undersized explanations that by doing some tweak in overflow i can get my desired size, now in here i have problem, how to do this, or tweak it in automated 2pass.
By not changing the ("Q1") ("Q31") to get my desired size, but i will lose quality here.

At last... some remedies against oversizing

If you get an oversized file, there are two solutions in order to get perfect file size:

1. Overflow treatment values tweaking
These settings are used during the second pass and tell the bitrate control which strength it can use to adjust the bitrate. Higher values allow him to be more efficient and to balance these Q1 frames.
So... recommended values are ("Encoding type" > Two-pass - 2nd pass > "more..."):
- overflow control strength: try 10 or 20
- Max overflow improvement: try 10 or 20
- Max overflow degradation: try 10 or 20
