Comment (by francois.visagie@…):
Replying to [comment:18 cehoyos]:
> aborting (without a crash as done with shorter input files with other
presets) is much better.
Perhaps '-preset ultrafast' handled the stats anomaly better in this
instance, but for the sake of correctness I should point out that I've
experienced no correlation between crashing and shorter input files.
I first experienced crashing when encoding whole DVDs and since it's
happened whenever these conditions have been satisfied:
* this particular input demuxed from MPEG-type format AND
* two-pass encoding with different output format on pass 1 and audio
filter on pass 2 AND
* '-preset veryslow',
regardless of input file size.
