After quite a bit of research, it has been discovered that:
- A script can be perfectly matched on your end, but it may not line up for others depending on their video source, even if it appears to be the exact same video with similar runtime and frame rate.
This holds for mainly 2D videos where there can be multiple sources to obtain the same video.
To understand and help others ensure they are having a good matched script experience and for consistency and avoiding frustration, here are my recommendations:
DO try to make scripts or playback videos using the Original (Free or Paid) Source, best through Direct downloadable clickable links on the video’s site.
AVOID using the program/extension “DownloadHelper” (https://www.downloadhelper.net/)
It appears this app only offers a type of ‘screen recording’ and introduces a choppiness/lag that has been confirmed to have issues with matching scripts
AVOID using any other Downloader program option that grabs or records indirect “HLS online streams” or “HTTP Live Streaming” of the video (unsure if this applies to all downloaders, but its safe to avoid)
Downloaders that record HLS or HTTP Live streams or don’t offer direct links to the originals source introduce a sort of frame rate drift which isn’t more noticeable until about halfway through the video, where the script will no longer line up (can be up to 200ms off), for not fully understood reasons.
Its a prelliminary finding and there may be issues with other methods, and please post here if you do find any other issues, but so far this is a confirmed issue and should help with scripting and playback issues.
