I don't work for VDH. I'm just another user, like everybody else. But I find myself
referring to past threads to answer questions fairly often. A proper user's guide does
not exist for VDH but you can have the next best thing by reading things people have
posted in this forum. This is a collection of threads that I consider educational. Over
time, I'm sure there's more items I'll add here. And others can feel free to do the
same. I hope this becomes a useful resource for newbies & old hands alike.
In some cases, the relevant information is not at the top of the thread. So when you
click through to one of these, don't just skim the first post. Read the discussion. You
may have to scroll down a few screens to get to the helpful parts.
This is an introduction to the basic process of using VDH to download a video. It uses a
YouTube clip for demonstration purposes, but the approach applies to pretty much all web
Since licensing is a question that regularly comes up here, this thread should explain
the philosophy behind the VDH license. It also touches on the philosophy behind this
forum. This thread contains a reference to another thread that explains how to deal with
a video you may have downloaded before you got a VDH license, so it has a watermark, &
what you can do about it.
Occasionally, a user has trouble purchasing a license. This advice might be applicable.
Might be. Not guaranteed. Just a possibility.
When you post a problem report here, this thread advises you how you should structure
your problem description:
This thread gives a more detailed example of how a large number of problems should be
Here's how you open the VDH Settings dialog:
If you do change any settings, be sure you click the Save button in the bottom right
corner of the dialog. Otherwise, VDH won't change its settings. I repeat . . .
CLICK THE SAVE BUTTON!!!!
Sometimes, you don't need to close all browser windows or even reboot your system.
Sometimes, all you need to do is reload the extension:
VDH comes with a couple of keyboard shortcuts. Occasionally, these shortcuts conflict
with shortcuts used by another application. This thread shows how you can deal with
It seems that more & more web sites are offering their content as separate video & audio
streams. We first enountered this in early 2020 when the Metropolitan Opera began
offering a free online opera stream every night to compensate for their being closed due
to COVID-19. They have now stopped offering the free streams because they are about to
reopen. But this thread is the main source for how to deal with a site that offers its
content as video without audio paired with audio without video. This thread documents
the history of how several VDH users (I was only one among the group) co-operated to
tease out the answers to the mysteries. This thread includes a detailed analysis of a
manifest. It contains detailed descriptions of how to use ffmpeg instead of VDH to
download these separate audio & video streams. We even dealt with the subtitles
(captions) for the operas. It's a long read but we put in long hours to gain our
hard-won knowledge. We felt a responsibility to share our knowledge. If you are
determined, you can gain the same knowledge with less trouble. Not less effort, just
less of the trial & error we went through. It's not easy, but nothing worth having is
easy. So I encourage you to read it & try to learn what is there to be learned. It has
turned out that many other sites use the same approach that the Metropolitan Opera did,
so what you learn in this thread will apply on other web sites.
These are some other threads that deal with issues of videos having pictures but no
sound, or sound but no pictures:
When you have managed to find & download separate video & audio files, it is not
necessary to do anything further with the files. VLC has a feature that allows you to
play the 2 separate files synchronously. Here's how:
But if you just really have to put the video & audio into a single file, VDH now offers a
tool to do that, as explained here:
Then there's this curious case. It may prove useful to somebody some day. I downloaded
something that played fine for a time, then suddenly the video track got twice as fast as
the audio track. This thread describes what I did to deal with it. The proper solution
would be to fix the file using a video editor. But my approach worked well enough &
didn't require that I install anything new on my system.
