Video Sync Issues when using Seekbar (SL2)
Hi, I hope someone could help us with the following issue:
We've made a page where we've inserted a 2 minute mp4 video file. Afterwards we've created subtitles synchronized to a narration audio track in the video file. These are simply textboxes we've timed according to the narration in the mp4.
When first viewing the slide, everything runs well. However, when using the SEEKBAR to jump forward/back (especially back) the video and subtitles go out of sync.
What we've attempted so far:
1. Inserting an .FLV version of the same .MP4 video. This simply cased the Storyline application to stop responding every time. So couldn't even test that.
2. Another attempt was to extract the audio from the mp4, and insert it separately. The result: the audio and subtitles remain in sync even when jumping forward/back with the SEEKBAR. However, the video playback runs 1-4 seconds late, out of sync with the subtitles and audio.
We would be so grateful for any insight or ideas on how to overcome this issue.
Some parameters of the MP4 file: 1080 x 524; 30 fps; 387 kbps;
