I recorded clips into MP4 with OBS. They have no issue being displayed in media player or in Premier, After Effects etc but in Sony Vegas this happens to the clips. It happens during preview and render and only with the clips taken from OBS, not other clips. I tried them in both Vegas pro 13 and Vegas 14 but still the same thing happens.
Unless there are other OBS users here who have seen it and worked around it? This could be problem with Vegas Pro and the MPEG4 video files that OBS creates. I would report it to MAGIX and see if they agree that the problem is with Vegas Pro and that only they can fix it. In fairness. MPEG4 is a very broad specification and it's impossible for any software to support all of it, but if it works with Vegas Pro's major competitors, it should be in MAGIX interest to fix the problem.
