i don’t think footage is damaged because we can watch them and there is no difference from the videos that we can render.. and also after some “non-rendering” videos, some videos render randomly.. every time we changed only 1 thing to find the exact problem but it didn’t work.. the only word that explains it is “random”.. it it wants it renders.. yesterday and previous 2 months i have no problems with my videos but today i hava a big problem.. i did not change the codec because as i said untill yesterday it can render our codec and sometimes still it can render our codec.. this completely kills us how can be such a problem it is the most illogical problem i have ever seen.. conditions are same for 2 input but some of them works some of them not.. please help
