2 pass encoding

untick the selection in settings > encoder settings > "automatic quality settings". Then go back to that same option and untick at the bottom where it sais "One Pass (ABR) Encoding". Your movies will now be processed in 2 pass. To speed things up a bit more you can also select mode > "quicker for extra's"

PiP by default always does a single pass at a fixed CRF for the sake of time. So in order to do 2-Pass for PiP, in addition to selecting 2-Pass in the quality setting, you would also have to add this to the INI. SECONDARY_USE_QUALITY=1

A crash? That's interesting. Wouldn't the program or operating system give some type of error message if that was the case? Or is there no error handling in this case?

Well, changing to 2 pass didn't fix the audio/video sync issues with the secondary video. Also changing the hidden option switch SECONDARY_USE_QUALITY=1 didn't help either. @jdobbs - Have you had a chance to obtain Monsters vs Aliens yet and got a successful encode?

@Moviewatcher666; If you were to load the playlist (.mpls) of the associated .m2ts/m2ts's that contains the secondary video into tsMuxer, then highlight the audio file corresponding to the secondary audio, does it say there is an audio delay?

If you are into testing.. :) and familiar with command line runs.. Determine which direction the audio delay is off. Make a copy of the mux_00024.meta, place it somewhere different than the original location (in your C:\) Edit the line where the delay is for your A_AC3, "E:\MONSTERS_VS_ALIENS TRANSCODED\WORKFILES\00024.track_6656.AC3", timeshift=2502ms, lang=eng If you think the delay is not accurate, try removing 2502ms. It will look like: A_AC3, "E:\MONSTERS_VS_ALIENS TRANSCODED\WORKFILES\00024.track_6656.AC3", lang=eng If you think the delay is off by 2 - 3 seconds, you could try: A_AC3, "E:\MONSTERS_VS_ALIENS TRANSCODED\WORKFILES\00024.track_6656.AC3", timeshift=5004ms, lang=eng You will have to "choose wisely" :p Remux this file. Upon its completion, you will need to do a "creative rebuild" back into/with the other files in the Workfiles folder :cool:

Perhaps a potential easier alternative to the above mentioned, you could try the program delaycut 1.3.0.0 on the secondary audio file to correct/test different delay values, and substitute the changed audio file for the original audio file in the Workfiles folder and do another rebuild only. Remember to name exactly as to what you replace, and always keep a copy of the original! :) Delaycut may or may not work with DD Plus files. ;)
