Hi there,
I´m experiencing a similar problem as described bellow by Marsha but w/ Elan version 3.6.0 and Mac OS X (version 10.5.4). When using "Selection mode" I can chose and annotate the first selection I make, but when I continue there is a dissynchronus of vid and sound of about 20 sec (that wasn´t there in the first take). With out th selection mode, and when I start the vid from the beginning, both sound and picture are in synch.
I´v tried downgrading to ELAN 3.4.0, creating new .eaf documents from beginning and chancing the vids I annotate, but the problem remains.
Hope someone has cracked this one already :o).
Regards Jake
Ps. The funny thing is that the dissycronus does apprear also whe I paly the vids on Quicktime, but not when I use VLC player. Could they use different codecs (original vid. format is xvid packed .avi) which creates the problem?

hi there, when i play a selection the sound doesn't come with the video, but sets in somewhat late. the delay makes a proper transcription rather difficult. the files are already downsized to 100-300mb max, but the timing is still bad. computer has 1.99 ghz and 1gb ram, don't suppose that's the difficulty. but maybe the programme needs some fine-tuning? what do you suggest? regards, marsha

hi everyone,
my sign language research group in brazil has found some problems with synchrony between audio and video using MPEG1 on ELAN - both on Windows 7/XP and MAC. would it be better changing it to MPEG2? or any other format? please, i need some urgent help... :(
thanks,
aline sousa

p.s. we have found problems with synchrony between video and annotations too!
Third party update, regular expressions
