This post has been migrated and imported into different systems over the years, I have not had a chance to format this post manually so it may be hard to read but I have left it here as a reference.
So last night was game night and I was recording the newly released XCOM 2 with BigSwedish for several hours using OBS. OBS allows me to record on multiple audio channels so that I have myself speaking on one channel, Skype and whoever I am talking to on one channel and the actual game audio on a third channel. This makes it easier to edit in Premiere but it also makes for some very big files. This morning I wake up to begin editing my file and notice that its 40GB and importing it to Premiere either seems to freeze my computer completely or simply crash the program. Thus I realized that I needed to cut this file into smaller pieces but I had no idea what program to use. Splitting the file would not be as easy as I had hoped.
One option is to use VLC media player to record the video that is playing and use the recorded file, however this did NOT work for me as VLC did not preserve the video quality and also seemed to mess upp my audio tracks. I kept searching and tried many different programs, some programs I skipped as they seemed to be malware/spyware (Be careful when searching for free stuff). Finally looking at some forum posts got me going in the right direction to find a solution to my problem.
How I solved it
Avidemux solved all of my problems. It basically gives you the same capabilities as cutting video with premiere pro but in a much simpler interface. This program lagged for a few seconds but had no trouble loading my video file. I could also drag the slider to the needed position and set the markers for when I wanted to begin my cut and end it (just like Premiere). Once you have set your markers all you need to do is save your video and you are done! I love that Avidemux has the ability to simply copy the video and audio output. Avidemux should run fine and be perfect for splitting video on Unix, Mac or Windows. I hope this post helps some users who may be stuck with the same problems I had.
If you know of an even better way of doing video splitting please do let me know in the comments below!
