Trimming

[lamapoo]

Greets to all.
I notice that when I trim a clip in between 2 keyframes in vdub, it goes back to the previous keyframe and trims it from there. I suppose if i try to add a keyframe in between these 2 keyframes, I will have to rencode the entire movie.

Is there an easy way to do this. I'm going to try triming my clips with dvd2avi and encode directly to avi's.

Also, let's say I put a keyframe every 30 frames. Will this increase the file size? I beleive to have read somewhere that keyframes are bigger than frames.

thanks.

What exactly do you want to achieve? Split the file, cut trash out? Maybe there is a way to evade reencoding the whole movie.

I want to take a movie and cut it into scenes and I have to do this for about 600 movies. What I'm currently doing is putting a keyframe every second.

What was terrible is I started a batch "not knowing that i couldn't trim a clip between keyframes" and there was about 200 clips. They all came out wrong. Some had 5 seconds from the previous clip, others were missing the end. My boss was kinda pissed.

Well, in that case i would probably cut the movies to scenes first and encode then. I don't know how much adverse effect on quality that much keyframes could have.

So in other words... your saying that I can loose quality using that many keyframes?

So you think it would be better using dvd2avi to cut my clips and then encode to divx?

thanks..

isn't possible in VDub or VDubMod in direct stream copy. It will always start your new clip with a keyframe. Please read about keyframes to learn why.

What you can do is select in DVD2AVI the frame ranges for your project file. If you want to do it in VDub/VDubMod, then you have to go for full processing mode, and that will result in a new set of keyframes.
