Couldn't possibly be more happy with this add-on....works like a champ, as advertised. Definitely recommend!

comodo e veloce

Puts a watermark in the corner covering about 15% of the screen. They don't tell you this until after the download completes.

The watermark is basically ransomware, requiring $28.50 to obtain a new version that doesn't ruin your downloads. Moving on to a new addon.

good job

Works well. At one point it slowed my PC down, might have been during a livestream, but other than that it's great.

非常好用,是好物.

A good tool. 很好用的工具

Eu estou muito satisfeito como o vídeo Downloadhelper e recomendo!

Очень удобное расширение. Сохраняет по папкам видео с ютуба и других сайтов! Спасибо разработчикам! Не лагает! Все понятно и просто

Very useful, reliable application. I can highly recommend it to everyone.

It it were not for recent unauthorized transactions on my card, which has me scared of sharing my card information on other sources, I would have given these guys the $30.00 donation.

ottimo

Works like a charm. Definitely recommend.

I've been using the Video DownloadHelper for several years and really appreciate having it to work with in downloading most of the videos I want to save. Of course, it's no longer of much use on a site like Youtube where many videos are set up so they can't be easily downloaded with such software anymore, but there are other apps for that kind of issue. I like the fact that I can download easily, monitor the size and progress of the file when downloading, and other basic functions. It's a basic, clean and user friendly software that works well for me.

Huge memory leaks. Went up to 2.4g before I purged it.

I've tried Video DownloadHelper as a YouTube-DL alternative to download a paid video I had rented on Vimeo. The extension offers to downloaded the 1920 x 1080 pixels DASH stream, and downloads it fast, but then it launches a transcoding (called an aggregation), even though I've disabled "Force H264 tuning in aggregation", which would have taken hours. It turns out the free version adds a watermark, which requires post-processing and transcoding. My understanding is that you have to pay €18.50 for a premium license to get fast downloads without transcoding.

I have turned to Downie 4 by Permute's developer Charlie Monroe, which is also paid at €18.99, but has the advantage of being up front about it. Alternatively it is included in the Setapp subscription service. It has a cleaner interface and it works with Chrome and Firefox as well as Safari and Opera, alas only on macOS.

tl;dr: Video DownloadHelper should clarify its freemium business model on its official website and in its browser extensions.

It's a great app to download videos. There's only one flaw: when the extension is enabled and you play a live stream on Youtube, the CPU usage goes to the roof. I have to disable it and reenable it when finished.
It also works on some sites but not in others. In many of them the video is jagged and you have to pay to fix it
