I have uploaded some vids on YT and have recorded them at 640×320 at 30fps and SOME of them have the HQ option for viewers and SOME don’t although upload settings were the same for both. I already know that adding &fmt=18 to the URL will allow anyone to view in HQ but how do you make ALL vids this way EVERY time (as a default setting) and how can I change all my non-HQ vids to HQ?
