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.
