I am trying to find the best settings for recording gameplay videos with the smallest FPS hit. When I record with "Video Format: Uncompressed" I naturally get the best quality (and file sizes in the stratosphere) MJPG Compression works well and is what I will fall back on if I can't figure out what my problems are with x264vfw. If I set the Video Format: x264vfw H.264 in Afterburner settings, and then in the sub options to these settings I get half decent video, but no audio (this only happens when the OUTPUT MODE is set to FILE) If I change it to OUTPUT MODE VFW I get both audio and video. The Video plays back fine in VLC player but if I import the AVI file into Sony Vegas I get massive video issues. This video plays fine in VLC. I'll be the first to admit I don't really have a clue what I am doing (I've tried searching Google but I can't find anything), I don't know what half the options on the x264vfw config options page even do. My main question is; Why do the videos set to use the x264vfw codec and OUTPUT MODE VFW get corrupted when trying to edit them in Sony Vegas? Why do I get good picture but no audio when set to OUTPUT MODE FILE. What are the "best" settings to set these too to get a good quality video (YouTube 720p Quality is all I need). I've tried searching to see what these options do but I can't really find anything at all specific to using this with Afterburner.
