The overall purpose of my experiment is that I'm trying to analyze some videos that I re-encoded from DVD for my phone. It is running pretty fast for the amount of data it's processing (125GB of raw video data as reported by the analyzer, the actual video files are much smaller than that).įor now, I am calculating the average luma for each frame (which is nicely just a single AviSynth command) and I have a python script to average that for the entire video. Run Video Analysis Pass isn't do any encoding I'm pretty sure so it sounds like it is already doing what you want it to do lol. It might help if you told everybody what exactly it is you are trying to calculate. Is there a way to get VirtualDub to execute a script without performing a "dub" operation? It occurs to me that this might be a ridiculous question :-)Īuthor althor1138 Time 2 3:36 AM Post linkġ0 minutes 350fps sounds pretty fast to me. I'm getting about 350fps during this process so that might just be all my machine can handle, but for an entire feature length film it still takes about 10 minutes (give or take).
The script can open the video just fine, but I'm wondering about performance.Ĭurrently I'm using the "Run Video Analysis Pass" in VirtualDub to execute my script, but am wondering if there is a faster method to use. I don't want it to actually convert anything, just do analysis. Hi everyone! I'm trying to use VirtualDub and AviSynth to calculate some things about a video file I have (I have almost no experience with video editing, etc.).
