I've published a video which unfortunately has an audio glitch. I added a voice-over track ripped from a video file to my video. For you to see what I mean I'll have to link to my video on YouTube. The link I'm attaching is time-stamped in the correct place so when you click it should play from the right spot.



Interestingly enough, I have a saved version of this sequence without subtitles and the version without subtitles doesn't have this audio glitch at the start. I'm just wondering, what did I do wrong? I really don't know how it happened.

Any thoughts appreciated

thank you]]>

Audio becoming more out of sync - by: glueburner https://www.lwks.com/index.php?option=com_kunena&func=view&catid=8&id=231626&Itemid=81#231626 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=8&id=231626&Itemid=81#231626
I've tried all 3 different imports, no difference. I've also tried exporting, it's still out of sync in the export. The original footage if I view it in media player is perfectly in sync.

How do I enter Audio in? - by: mikeomg11 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=8&id=231547&Itemid=81#231547 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=8&id=231547&Itemid=81#231547 Audio Thu, 31 Dec 2020 02:41:45 +0000 Audio Lags Video after import - by: mrkaram https://www.lwks.com/index.php?option=com_kunena&func=view&catid=8&id=231203&Itemid=81#231203 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=8&id=231203&Itemid=81#231203 I tried importing two video files both 720p, 30fps, one recorded using an iphone and another using a Nokia Android phone.

After importing the video when we play it, the audio lags by few 10ths of a second but clearly visible in the sequence window (top right).

Same video works fine in all Media players - no sync issue.

If I export the video using Lwks there is no sync problem.

I need to import many such videos and sync them all to the audio track of the first video using the preview window and matching the frame where the singer sings the specific lines.

How do I achieve this when the preview does not show the "true picture"
It appears that the view window shows a sync problem while playing but not when exporting.

Pl help]]>
