AMVs shouldn't have blending unless intended but it's common

[x_rex30]

I notice a huge amount of videos have blending in them and I don't know everything that causes them.. but I've learned a bit about it and how it's not suppose to be there from neuron2 at the doom9 forums(witch is always a huge help and I give him props for helping so much). So what causes it? I've learned if you deinterlace wrong it could cause it, slowing down or speeding up your footage in editing programs like Vegas and Premiere can cause it but there are settings in each program that'll prevent it.. and I think if you change a video from 29.970fps to 23.976fps or any sort of fps adjustment for that matter can also cause blending.. here is an example of blending.



If anyone could help educate me a bit about it and spread some light about it I'd like to hear.. I think they mention something about it in the guides and they show some end of eva footage with blending in it. Anyways please leave some feedback about this if you know anything about it.

Some sources are frame blended by their very nature (original R1 release of NGE comes to mind).

I haven't really noticed it very much, but I'll bet that most of the time it's just people forgetting to uncheck the "Frame Blend Speed Changes" box in the clips' Field Options in Adobe Premiere Pro. I mean, remember all the trouble we used to have with people forgetting to uncheck the "Deinterlace when speed is below 100%" box in older versions?

The thing is I see this a lot throughout videos even when there isn't speed adjustments.. I use to be lazy about deinterlacing and I just used field deinterlace and it would get rid of interlacing lines but caused blending witch is hard to see to the naked eye. Even though I had blending I tried deleting frames with the blending and maybe sometimes making copy of single frames to replace blended frames. I don't do that anymore.. sometimes I run into footage that is so hard to deinterlace and make clean that I just go ahead and let it come out with some blended images.. I have that problem a lot with pure interlaced footage.. this problem was really hard to fix with "Ninja Scroll" and "The Guyver", even the people at doom9 had trouble fixing it.

In my AMV, I used an old anime that had a bunch of blended frames. I gave up and just FieldDeinterlaced. Many old anime were animated a very low frame rates and to achieve better moving images the animators used blending to smooth out the motion. Newer anime shouldn't have this problem unless someone didn't properly de-interlace or used a lot of speed changes on the source footage. OR, the source was from PAL DVDs for which many times blended frames is a given.

Proper decimation of 29.97fps -> 23.976fps material, on a properly telecined source, will not cause blending, since you're just eliminating two sets of duplicated fields.

You can blend frames to get the procedure to work out, but it isn't necessary.

I prefer having blended frames when I speed up/slow down video, I like the way it looks.

What? It's my video.

All three of the R1 Sailor Moon movies released by Pioneer are blended throughout. It makes editing a bitch, especially when you want to do frame by frame stuff and cut out overlays.
