iMac user Why for example I have English and Spanish subtitles for some movie (avi) the English one matches perfectly and even if I match the first lines for the Spanish one after some time the Sync starts to fail? I use Submerge software. Thank you

Hello Francis! 

Make sure the Spanish subtitles are in sync with the timings. You can use SubtitleWorkshop to sync the Spanish subtitle with the movie timings. Following this tutorial will make it a bit easy!

Have a nice day! =D 

Maybe the sub files have different FPS, or something has been cut out/ added in between. Post the links to both English and Spanish files so we can take a look.

Hi, For example two files for Once upon a time in the west, Can I upload two files at once, and how? Thank you Francisco

Hey Francis,

Why don't you upload the first subtitle, and then the other one. No need to upload subtitles quickly, my friend. 

 Try this

hey buddy , get me all the subtitles u want and i'll fix the timing for u

but plz mention the release name or at least any other script which is already fixed to ur video version

Thank you everybody, I think Subs Factory can fix subtitles for Mac users, I've fixed some of them and of course I'll donate something. Submerge can fix some problems, I recommend it, I donate a few bucks. Great application. Francisco
