Disclaimer : I was one of the lucky few that were able to see the video before being officially launched.

Like I had the opportunity to say to Cyrus, the amount of effort that he and his team have put into this video is great. I would say that it catches - and embodies - the spirit of our forum, albeit much more things will be sure be made in this field. In the same spirit of sharing feedback, here's my feedback on the video when I was given the opportunity to see it (split into "Pros" (Positive) and Deltas (Things to improve)):

Pros:

• I dig the early animation (around 00:08) mark. The graphics are really well made and, for a first video, it nails the whole vibe of the video. Sure it could be improved, but as a first result, it looks good.
• I really like the fact that the whole 6 minutes of the video is simply towards one goal - To talk about Bitcointalk and highlight some of its boards + some other facts that we are known for (like signature campaigns). It's good to reckon that even we (as a community) reckon that some of them generate spam but, then again like you said, " A bitcointalk signature became a signature of Bitcointalk".
• The host himself seems that it may be his first / few times recording something like this - in general, not specifically crypto - and he's pretty good at it! What I can say to improve is perhaps trying to act even more natural and try to avoid that he is reading something of a script in front of him (in some shots looks more than others)
• I also like the idea of sliding "future" topics that will be approached in the channel but without giving to much information about them. It's a good way to catch the attention of the viewers and make them see future videos if they want to have their ... curiosity satisfied. Good one!
• Good shout for WO thread! I'm sure this could be a good segment where we could highlight good threads of our community

Deltas:

• I think that the initial transition that happens here[1] is too abrupt - the host doesn't even have an opportunity to end his phrase and the introduction is already happening. What I think that it could result better - as not to just jump from one segment to another so quickly - is to perhaps to add some kind of effect to the introduction effect where it starts with some sort of fog and then proceeds to clear into the animation itself ... Reading just seems odd, but I was just trying to "ease" that transition from recording to animation without feeling so much ... abrupt.
• This may just be something that I noticed, but I tend to think that some sections of the subtitles just fill the whole screen - these[2][3] for example - and it ends up distracting the user who ends up choosing to have them. Subtitles can ruin or improve the experience one has and I think the current ones could be better sectioned and balanced to both decrease the amount of characters per line / section - thus reducing the number of characters / s - and also trying to give enough time for the reader to read them. For example in these sections[4][5] the subtitles disappear before the host finishes the sentence or they go out too quickly compared with the speech. I think its overall a good effort, but I can clearly see that the subtitles were made considering some script and pasted on the right timings. I think with a little bit of work they would get awesome Here's a few tips that I followed when I did those jobs (more hardcore times I guess):

  • I always used VisualSubSync to time subtitles. It gives a lot of information (characters / line, chars/s, total characters per section) and it's really a breeze to work with.
  • I would try to have a maximum of 35-40 characters per line and 80 per subtitle.
  • The character/s value should be between 17-20 so this gives the viewer enough time to read the whole subtitle;
    
  • Maximum duration should be around 5-6 seconds but that depends on the length / character/s value...
    
  Again, these are just the rules I used to follow - and that I employed on my subtitling job - and I don't intend to tell you they are the perfect rules. I find the end result that comes out of them good and balanced, and hence why I'm sharing this with you.
• The balance between host time and graphics/informative content could be a bit more balanced. We get the host most of the time - which isn't bad, he is a likeable character - but I don't know if his presence is too much and should be balance with some other kind of animation or more screencaps of our forum. The first time I saw it I though of that, but on my consecutive views I didn't felt that ... Perhaps I got used to his presence?
• This is just nitpicking but the "Dislike" button animation isn't showing[6]. I don't know if it was on purpose (that would be funny) or not but I though you should know.

I initially noticed that this cut[7]  wasn't hiding the upper right corner of the video - something that then happens throughout all of it. At the time I was only able to find this[8]website but now thanks to other members I've found out that the company is related - in a way - to your forum. Isn't it incredible to see the amount of "work" / "endeavor" that this forum has generated these years? Remarkable I would say.

As for the future, I think it looks bright. I'm sure that you've noticed, but Cyrus actually heard and implemented some of our suggestions in a way[9][10][11] so far, which shows that we are being listened and our opinion is valuable. I don't think there's a better feeling in a community than this one (at least on this matter we're discussing).

I actually talked about the sustantability long term of the channel in one of my initial[12] posts:
I agree that these are not groundbreaking ideas, but it's a start. Considering that we're talking of a team that's already between 5 and 10[13] people, whatever is the amount of time that they are dedicating to the channel they've got to be paid somehow and while I know that theymos has stated that he might consider some funding, as a community project I wouldn't mind donating some BTC whenever I could for the project.

While not ideal, I listened to this video while doing other things and the result wasn't bad (as in absorbing information/paying attention to what was being said to me). For sure that some videos won't be like that and will have more graphical information / content that actually needs to be seen, but I guess that if we want to really show our vast knowledge in some areas, there's no way of circumvent that kind of visual information... I do believe that if we get interviews with members of the community or even renowned personalities (actual ones!) within this field in our channel, I'm sure that you'll be able to grab the audio version of the video and play it on your favorite app (check AntennaPod[13] - it's open source. While being basic I feel way more conformable knowing that anyone can audit the code).

On another note, I'm not sure if you guys noticed, but Cryus added English and Portuguese subs to the teaser[14]! Thank you for that!
