This flixpress website have templates that you can add to the beginning of your videos, called youtube intro, video intro, like an ad thing, in which you can have a brief introduction of your channel, telling what's your channel usually talk about. Of course you can record a short video like 5 seconds, I do think do it yourself DIY is the best, talk what your channel is about, like "welcome to my channel eg:BudgetGadgets, on this channel I will have kinds of unboxings and reviews, most tech related. " rememember this: don't make the youtube intro too long, people won't be glad to watch a long ad, I think 5 seconds is perfect. Then later whenever you have a new video to upload, you can add your intro, combine the two videos to one and then upload. So, this is a simple explaination about "what's youtube intro means" .
Now, about flixpress.com ,
As I refered, it's better to do the youtube intro yourself, but if you are lazy, or just don't know how to design your intro, don't what to say in DIY intro, you may want to try this site, flixpress.com .
At the very beginng, when I first know their site, seems their templates are all free, I tried many templates, almost all.
Here is my first test of the website flixpress.com box template. This video get more than 1300 views, the first video is also the best flixpress video on my channel, which get so many views, while other flixpress videos didn't get so many as the first one.
