I'm new to EVOdemux and I think I'm not handling frame rate properly.
I have some EVOs which I want to convert to something playable on my PC (ex; .m2ts). From what I hear, the starting point is EVOdemux. I have v0.628.
Choosing my smallest EVO as an example, I have included the EVOdemux Status window at the bottom of this post.
EVOdemux says at the beginning that the EVO is 12 minutes and 32 seconds long. I've watched this video before and I know that to be an accurate time. EVOdemux also says that it is a VC-1 video with a frame rate of 23.976. So far, so good.
Toward the bottom of this EVOdemux analysis are two lines; counted frames and calculates frames.
First, let's talk about the counted frames line. EVOdemux physically counted 22,540 frames. Then, EVOdemux did some fps math to determine that, using a frame rate of 23.976, the video is now 15 minutes and 40 seconds long? Why is this different than the real video length?
Now, let's talk about the next line, calculated frames. EVOdemux calculated 18,035 frames. If I do the fps math myself, at 23.976, this exactly matches the real video length. Why are the calculated frames different than the counted frames?
I'm new to EVOdemux. Can someone help me understand these lines? I want to make sure I get the EVOdemux step right before I use tsMuxer to make my .m2ts.
