I tried it on a video where people were talking pretty quickly, and the captions were handy because I could glance down without pausing. The part I ended up appreciating most was being able to move the captions out of the way when they covered something on screen. I usually find subtitles distracting when they sit in the wrong spot, so that small adjustment made me actually leave them on.

Rewinding and pausing streams to catch lines got old fast, so I hung my hopes on this doing the minimum. The first minutes were the surprise: subtitles appear as speech continues, no tab switching, and the translation to my language just sits over the video. It also worked on a webinar, not only YouTube. I resized the text and moved it lower so faces stayed clear. Latency settled at about a syllable behind the speaker.

经常观看外网课程视频，这个扩展对我特别实用！很多视频没有适配我的语言字幕，它可以实时检测并翻译。延迟很低，非常好用。期待以后持续更新能变得更顺滑。字幕支持一键开关，适配多个网站，不用反复调整设置，简单易用。

I have been wanting something around the same lines and this extension is the best bet. It's a God send as now I can have the translation on any video I am watching. I tried it on different platforms and the experience is consistent and as per expectation. I would highly recommend it to others who want to turn every video to be watchable without and language Barrier. Thanks.

对我来说非常实用。我经常看课程视频，也习惯把字幕放在画面的上方。大多数时候延迟都很低，相信随着后续更新，使用体验还会更加流畅。字幕可以直接开启或关闭，也支持多个网站，整体用起来非常方便。

Waiting three days for the community clippers to subtitle japanese gamin streams was reduce on my patience ; now I'm able to watch unscripted late night VTuber banter and indie game streams as they happen live .The translation engine keeps up with extremely rapid speech without requiring me to pause or constantly scrub backwards!! Just by still adjusting the font size and the text contrast I keep the video looking perfectly clear. Their low latency processing turned out to be pretty decent.

It is a good tool for learning new language as well but use it will caution of course as learning new language can be daunting task.Previously didn't understand a single stuff russian twitch streamer says,this add on helps me with that as i watch a lot of cs2 streams on twitch.Multiple platform support is plus even though i mainly use it for twitch though. Latency is pretty low i would have to say and chat can be customizable which can be helpful for people with some sorts of color blidness i guess.

Sometimes on youtube there might not be a any caption availble on languages that i don't know but i need to check that video for either educational or for to learning purposes.As ai getting more involved in our life it is good to see its usage gets put to interesting usage like this. As the caption was able to pick up with speech going on forward it works i would say.Also if i dont need captions for example some videos captions already available i can turn it off saving ram + no read write going on my windows 11 laptop.Another interesting usage is when someone learning new language it might help them as well

frequently watch foreign-language livestreams or videos and wish you could understand them without waiting for subtitles, FlashCaption makes the experience significantly more accessible and convenient

Useful extension used recently,specially adjusting option for the caption placement on video is unique as well as very useful.I usually place the caption on upper portion of the video specially lecture video on greek history. They have said that the latency is very low which true for the most part,but as it is getting updated it will get more smooth over the time. On and off between caption s decent as toggling between on and off along side with multiple website support is really cool.

The real-time captions appear quickly and the translation feature makes it much easier to follow YouTube, Twitch, webinars, and other video content without constantly pausing or switching tabs

Honestly speaking, I am a big fan of Korean Drama and Movies and I was literally looking for something which can translate without lagging! It did an amazing job. Also, the best part is instead of installing big softwares it gives all the features in just one extension which takes about 1 minute to install. Would recommend it to everybody.
