Uploading videos

[quote=Elexias]Hello I have one question, maybe not related to this forums, but I have filmed most of my games with OBS and I want to edit them somehow, friend gave me Vegas 13 PRO and I can't edit them as videos are in wrong format, not sure how I can change their format, tho friend told me that Vegas won't work with those videos, I open those videos with BS Player, and they're filmed as I said with OBS (program for streaming/recording), I want to edit them somehow to cut some things and post few videos in my guide, can you suggest me some free program that is easy to use so I can edit my videos and publish them?[/quote]
