is there a way to get an idea of the quality of the video and if the conversion succeeded or did it quit in the middle of the conversion.

It's libx264 log file

Add --ssim and/or --psnr (-ssim and -psnr in ffmpeg) to get those measure of quality and it will print the values in the log. But they are problematic objective measures (don't correlate with HVS very well). You an use --tune ssim or psnr and get mathematically higher test values, but they look worse subjectively. Use search if you want more info - this is a big topic discussed extensively

If there was an error , or it was aborted - it should say so in the other parts of the log that you removed. You can double check by adding the frames, I+B+P compared to the original framecount, or the log should tell you how many frames encoded at the end (looks like you removed it)
