If anyone is having issues rendering then they should contact me. Often it is a single video file that is causing problems. So, short answer: 1) yes 2) I assume you mean a "proxy" of the video frames.... no 3) yes The longer answer: The recording and exporting process is fairly simple. First you record your session. If you need to record audio, then you also need to run and audio cable from an output of your mixer back into the audio interface you want to record with. Your performance is saved to a file. This file only contains the information needed to reconstruct your performance. Once this is done you can open and export the performance any time you like, and as many times as you like - though I would recommend doing it sooner than later if you're the sort of person who often re-organises or re-names their video files (only to spare you the hassle of re-linking them). There are some handy presets in 1.4.0 that allow you to select some fast and fairly high-quality options for exporting. If you don't want to use these then you can choose one from the ones available on your system. But, if you do this: 1) be careful to make sure that you select a decent frame rate (e.g. 25 or 29.97), as the recording has no concept of "frame rate". 2) I would recommend against using any multi-pass encoding options. This is because multi-pass encoding using H.264 passes through the file 4 times - which will take you a long time, as the performance must also be rendered (i.e. 2 video streams decoded and processed with effects/transitions) using MixEmergency 4 times over.
