I really hate the fact that you're not using SWF files anymore since you're still using comic book word bubbles for dialog & I have to repeatedly pause the video to make sure I don't the skip dialog; whenever I pause the video, the video title & author credits appear & block the text. Honestly, hitting the space bar on my own time was more serviceable than racing to make sure I read the subtitles before they went away. If you're gonna ditch using SWF files altogether, I suggest getting voice actors instead, we have plenty. Otherwise, bring the SWF files back, just for convenience sake.
If you really have your heart set on still using video, the good news is that you can actually use both. I myself have done this with my latest submission because the SWF export was 96 megs [I used 2160p+ images for backgrounds].
Fun fact: you can actually get 1440p with an SWF file but Newgrounds doesn't display exported videos in any dimensions above 1080p and Newgrounds doesn't limit the height and width of SWF files. Ironic, isn't it? In fact, upon rewatching the original first episode, I see there's an option for both the SWF file & MP4 video. Whether or not this was done for you by the staff, I have no idea, nor any opinion.
Personally, I don't get the point of this needless reboot when the original has yet to be finished. I understand that you take umbrage with the way the originals were made but the way I would do it is fix the things I deem as being fucked up and then swap the files. It's what I eventually intend to do when I remaster my old Flash movies. I mean, this is the second time you've remade this specific episode.
I honestly think the new intro could've been done without, it's not really reminiscent of the classic DBZ intros until the very end and even if it weren't for that being an element, the intro would still be underwhelming in its own right. I cannot conceive of watching it every time you submit a new episode.
Whatever, not my problem.
