This site was born out of a need, and now look at us, we are strong and ready to help our fellow twitchers to untwitch and get on with their lives without too much of data transfered in the process. We have also thought 20hr videos may not always be what you're looking for, so don't forget to adjust start and end of the video stream to download. Our system will always offer to download about 1hr long chunk from the start of the video, if said video is much longer than 1hr. Do not be surprised. This is done to avoid timeouts and broken downloads.
Also we cannot provide exact filesizes, doing so would require multiple additional servers that would scan 100s of small files, so.. no, we can only offer estimated file sizes.. That said, always check with the info online to see how much of a download to expect. 1hr or shorter videos may have an exact size listed, 1hr can be as much as 300-500 files involved in the stream... We will write more about it in the blog.
We do get emails all the time asking this and that.. Mostly to put up ads here.. We don't want that, so.. Don't contact! But honestly, if you have a question, check out these most asked ones that we made our answers public to. Cause it's faster than answering all the time.. But if this here doesn't satisfy your thirst of knowledge, there's an email below...
As a precaution not to overload the servers, we do this preemptively... But you can always adjust start and end before download begins. Just watch out for the 2 white boxes with numbers next to download button. If such boxes are not present, video is not longer than 1 minute.. Or it's a clip. Clips are short.. We do not offer partial clip downloads.
Also there's a download link built-in to standard html video player. Simply find the vertical tri-dot symbol, it's the menu, it always has download button. ..
