It's often about software/hardware. The fact that you didn't even go into the hardware specs & OS might lead one to think you feel it's not important, when it usually is ;).
Also, IME, starting with a clean windows install is essential for good QC. Like he said- video editing can tax a system, especially a non-multimedia rig. Not to mention, the windows registry can get messed up in a hurry unless you know what you are doing (see unwritten chapter 'codec horror' for example of frustrating topic).
Give us more info on your system, content, etc. and it can certainly help provide a troubleshooting starting point. Avidemux is normally a stable app IME and O.
So, I have been using avidemux for a long time and love it. I just got another software, but it's not as good for simple, single file video editing and converting. What I need is a program like avidemux without all the crashing/bugs.
All I need it to do is cut parts of the video out, aka editing it; choosing which codec to use (x264, xvid, etc), be able to choose the container( AVI mp4 etc), be able to choose the quality of the video (CRF 10 CRF 20, etc).
I would like to be able to for example select an AVI file and cut out parts of it, change the quality to decrease file size, and be able to transcode or convert it to mp4 or AVI or etc.
Does anyone know a good one for this? I don't like the super advanced ones for movie-making because they want you to make multiple layers, transition between scenes, etc. My videos all have one scene, one file....
Thanks in advance if anyone has a suggestion!
