Video lags audio after edits

[Olga Krovyakova]

Hello Dwight,

Thank you for letting us know about this.
As soon as there will be any news on your previous report, we will post it here.
Thank you for your patience.
Have a good day.

Olga,

I apologize. I found the sync issue in this case was introduced by another app I used to amplify the audio. That app had been working perfectly but it turns out that the latest update has a bug. Thank you for your help.

Hello Dwight,

Thank you for your post.
Could you please send us the original input file that you open in Video Splitter and the project file? You can upload it to any file sharing service, e.g. Google drive (https://drive.google.com) or Dropbox.com.

To get the project file open the input file in Video Splitter, set fragments for saving and deleting then go to File menu -> Save project as and select folder to save the project file.

Here is the guideline on how to upload files if needed.

Olga,

After editing a number of video files with external SRT files editing disabled, I found this works most of the time -- but not all of the time. A 71-min video file I recently edited that included internal SRT  file editing also went out of sync (300 ms) at an edit around the 16-minute.

Olga,

You're welcome. Thank you for the update and for the subtitle tip. So my workaround until your fix is made will be to merge the external edited SRT file and make it internal ahead of running the project. This will work fine.

Hello Dwight,

Thank you a lot for files you have uploaded and your time.
The issue with async was reproduced at out end and will be fixed in the near future.
As soon as it will be fixed, we will post the news here.

I would like to draw your attention to the fact, that if the SRT ID:4 subtitle stream editing is disabled in Control / Select streams menu, the issue with async doesn't happen.
So if you do not need this subtitle track in the output file, you can leave it disabled (as it is in your project file).

Thank you for your assistance in this matter!

Olga,

I no longer have that project file. So instead I have uploaded another set of files for you that includes the project file. This one was even worse, with video in the edited file lagging audio by 800ms by the end of the video. In saving the new file after editing, I include the video file, the audio file and the external SRT subtitle file. I reran the project just before uploading the folder for you and the results were the same as before.

My edits are primarily to take out language and video that is inappropriate for family and younger viewers, i.e. 'f' words, the word god when it appears before damn, nudity and sexual material. I use the latest video splitter version on a Windows 11 Pro desktop computer. The link to the new folder is https://drive.google.com/drive/folders/1BOgOkGmI-VV6V5214imWSyfxGpiNnA56?usp=sharing.

Hello Dwight,

Thank you a lot for files you have uploaded.
Could you please also share the project ssp file from Video Splitter from this edit?
I've decscribed in a previous post on how to get it.

Olga,

Original and edited video segments chosen as an example have been uploaded in a Audio Sync Issue folder. Note the audio is in sync throughout the original segment but is only in sync at the beginning of the edited segment. The folder has been shared with anyone with the link: https://drive.google.com/drive/folders/1opgyHbn02v0kKvJMkfW8-W9Lnkv-iu0u?usp=sharing

I'm having trouble lately with video lagging audio by 100 to 500ms or even more sometimes after making multiple edits. These lags can appear after any edit, from early in the project to later on. As a result I'm often forced to extract the audio and edit it after finding mis-sync points and add in noise to resync the tracks. This is using the latest version of Video Splitter.
