.SPK File Association 4. File created by Bright Spark, an educational application used to teach electronics principles; contains one or more electronic designs as well as written text that teaches the reader about the design; saves the information needed to present the lesson in the software.

this video plays in a app , so there is no way idm or any other downloader can catch the video
I think buddy instead of posting these in separate posts, you could have added them in one post.
Also you have given enough data, if someone can help then they will until then wait.
My take is that they have obviously encrypted the text so that it works only in the app.
And as rightly said by @ankushitguy many of us here are not hackers, so try to help yourself by Googling as that’s what others will do to help you.
share the file with me coz pk is a header of zip file let me try that
First of all let me correct you, .spk isn’t a format, it is a Extension that contains in specific softwares to let it open or let it view or convert. 2nd of all there is no Official information so far about .SPK files that what it does and why it exists. But there are specific programs that opens it and give you few solutions too.
Programs that open SPK files:
Windows:
Mac:
Linux:
SPK files are saved in the .TAR format. Therefore, you can also open them with any TAR archive extractor.
Software that will open, convert or fix SPK files:
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
@s_b Google does help, Until unless you use correct keywords, So please google search and try to find your solution. Don’t say solution not exist anywhere, Actually you haven’t reached to it so far, so kindly research and find out where it remain hidden or visible. That’s all mate!
