9animetv audio file not in sync

[jeterfan]

When I download a file from https://9animetv.to/ the audio is out of sync with the video. It seems that the beginning of the audio is missing, causing it to play ahead of where the video is at. I have tried multiple videos and used both chrome fire fox with now luck. This issue is not present on other websites so not sure what the issue is with 9animetv.

Thank you for any info

There are a few things you need to do.  First, get VDH 8.1.0.0a5 beta for Firefox.  (There are no betas for Chrome & Edge.)  When you install this version, you get a congratulations screen.  Don't ignore it.  Read it carefully & follow the instructions.  For further explanation of what it says there, search for a thread on here with the title, "How to download from YouTube."  Look for a post within that thread dated July 17.  Follow the instructions in that post.  Even if you've done that with earlier 8.1.x versions, you have to do it again.

Second, get CoApp 2.0.4.

Where can you get those?  Look here:

Be sure you expand the entire thread.  Then search for "various pieces" within the text of that thread.  That will give you a link to instructions showing you where to find the various pieces of VDH, including the VDH betas & the releases of the CoApp.  On the CoApp page, be sure you click the item that says, "Show all xx assets."

Third, use the new Side Download function.

You can see my results with all of that in the attached images.  (I'm not sure what order Google is going to attach the images in.  To get the story in chronological order, read the images in ascending numerical order of file name.)  It's a bit hard to tell if audio is synched with video when the characters are animated people.  You can't accurately match the voices you hear with the lip movements you see.  Plus, as an added complication (at least, for me), they're all speaking Japanese.  That's an assumption since I don't speak Japanese.  In any case, a skimmed through this file & it seemed like the audio synch was fine from the beginning to the end of what I downloaded.

I have to say that I have attempted to go back to that same anime & the site refuses to
stay on that web page. It displays for a moment & then flips me back to the home page.
I have manually entered the URL into the URL bar. I have also done a site search. It
gives me that video as a search result. But when I click on that search result, it still
goes directly back to the site home page. It's quite annoying.

I was going to try to figure out why the audio might have been out of synch for you. My
suspicion is that there is timed_ID3 data in the video. Old VDH had trouble with that.
New VDH with the Side Download ignores that so it's no longer an issue. But I can't get
the site to show me the page again so that remains pure speculation.
