i am willing to make big unique text Style pack for that Can a video as help file can be in be included in main file?
I think better option is to include in main files, for example in help.pdf or help.txt a link to video online (Vimeo, Youtube etc.).
Yes, of course it will help. You can put it in the description. If you know the html code for posting a youtube video on a page it would be an advantage. Best of luck!
I think it’s possible to include in the package, but why do that when you can just upload the file to a video sharing service, which would help save bandwidth, reduce package size, and more over to save you in case the buyer cannot open your video file
Do not put it in the .zip file you will get soft rejected. I did this myself and we’ll learned the hard way lol just upload your video to YouTube or your video service choice and make a link to it in the description. For yur help file just do a .pdf or .txt file. You can even post a link to your video in the help file.
