Error: 2pass curve failed to converge

[enchant]

I do most of my encoding without any problems on my desktop PC running WinXP. I've got a fairly new laptop with more powerful hardware and Win 8.1. I installed all of the exact same software on my laptop that I have on my desktop.

On the laptop, I tried encoding a video that successfully completed on the desktop PC. The good news is that it appears to encode a LOT faster. The bad news is that it fails at the end of the second pass, although it reports some of the error soon after the start of that second pass. Here's my log:

It looks like your script was outputting an error screen or black screen or the like, so it only came out at 17kbps.

[enchant]

Is there any way to know what this error screen might have said?

[Atak_Snajpera]

open script in mpc-hc

[enchant]

I'm afraid I might not have enough background in video encoding to do this. What do you mean when you say "script"? I've got the source video (which is fine), the subtitles, and a .wav file for audio. And the .avs file that I load into MeGui.

[Guest]

The .avs file is the script. You can also open it in VirtualDub (File/Open video file... and select the .avs).

[enchant]

It doesn't display any video. Only audio. But on my desktop (which encodes fine), it does the same (no video).

[enchant]

I installed Virtualdub and it was able to open the script ok, showing the video correctly.

[Zathor]

It seems you are using a very outdated version of MeGUI. Please post the full log (especially the versions part at the top) and update MeGUI and the other tools. Also the content of the avs file should be in the log.

Likely that is not the problem but who knows...

[enchant]

I tried updating MeGui, using the update app within the program, and I started getting errors that I couldn't correct. So I went back to what's always worked for me. Is that what you're talking about, or do you mean to download a new version and overwrite what I have?

[Zathor]

Download this build and extract it to a different directory:
https://sourceforge.net/projects/megui/files/latest/download?source=files
Reproduce the problem with this build and post the log.

[enchant]

The new install of Megui straight out of the box appears to be working fine. I'm getting good encodes now.

Thank you very much for the help!
