AC3 time correction

[keithmac]

Hello all, I`ve had a good look round the forums, and the web and I`m still at a loss to be able to correct my AC3 files when I convert from FILM to Pal video?

I`ve tried the BeSweet gui with AC3machine but when I hit the button nothing happens? Also tried copying the command to clipboard and pasting to a CMD window but still nothing?

Also people have commented on quiet audio when using BeSweet?

All I need really is a failsafe method for altering the "framerate" of my ac3 file, even an example comand line to use with BeSweet would be good :)

What`s eveyone`s experience with this AC3 altering?

I don`t want to do a 3:2 pulldown on playback and use NTSC as I`ve found pal gives a better picture on my pal tv, it`s just the sound I`m stuck with!

I`m gonna try Goldwave tomorrow, but at the moment it won`t take my AC3, even though I`ve fixed it with BeSplit, this audio was originaly from a VirtualDubMod Demux of 2 appended files, goldwave stops loading it at the join half way though (will try joining the 2 halfs with besplit, fixing before and after and see if that sorts it?)

Any helps or tips would be great, I`ve been bangin my head against a brick wall for days trying to work this out!

Back again!

Found out that besweet dropped the ac3end.dll in 1.4, then added it back in 1.59 so I`ve got the AC3Macine gui working!

The ac3 is now the right length but too low volume (a largely discussed problem with the ac3enc.dll).

Has a look about again today and someone`s suggested using the -ota ( -G 1 ) setting for post gain? in besweet, will try that.

Anyone stubled across a proogram for displaying the ac3`s (so I can look at before and afters and determine what`s happening?), also will I be losing information (clarity) from the quieter sections of audio because the output from ac3enc is too low?

Ever get the feeling you`re talking to yourself ;)

Righ them decided in the end to use BeSweet to alter the "framerate" to 25 fps and output 6ch wavs. Using Soft Encode to rebuilt the AC3 stream, just a question;

As the wavs have come from a film AC3 do I still need to alter the centre/vocal channel, it suggests -27db but surely this will already have been done and the centre .wav will already be louder? For the time being I`ve selected -1db, same for the surround channels.

Also what`s the loudest you can go with the channels before you get into problems (obviosly not high enough for clipping to occour) are the AC3`s set low for a reason (hardware/dvd issues?).

Any replies would be helpfull :)
