Used MKVCutter and MKVToolNix to try and cut a few second section so I could convert to GIF. I used keyframe before where I wanted to cut and second keyframe after since it's easier to edit out extra frames in GIF. I keep getting corrupt video that looks like 4 video (like the security video footage) and in acid-tripping mess of color. I tried going back additional keyframe for the start, I get same messed up result.
https://youtu.be/32k_6y7cZuU is what I get.
The original video plays fine in MPC-HC and VLC. The preview in MKVCutter and such shows normal video so it appears to me something is getting broke when I cut the video. Any idea or suggestion? Video to GIF I've used don't like dealing with 90-minutes long video and Photoshop only works with the first 500 frames. I haven't tried online EZGIF site since my upload is capped at anemic 64Kb/sec and it would take me a day or 2 to upload the 1GB video file.

Be sure you are cutting BEFORE the keyframe of what you wish to retain. Different players, editors will vary on which is a keyframe and some count from 0 and editor may count from 1. Also filters such as trim have their own counting system if you use them.
This looks like the absence of a starting keyframe in an mp4 container. I have had good luck using AVIsynth:
Code:FFmpegSource2("C:\Users\Bud\Desktop\[dp]Manjandani-1.mp4", atrack=-1).Crop(0,0,-0,-0).LanczosResize(720,304) ScriptClip(Last, """Subtitle("[ "+Chr(FFPICT_TYPE)+" ]", size=(Height*56.0/720), align=2)""", after_frame=true) Subtitle("C:\Users\Bud\Desktop\[dp]Manjandani-1.mp4", x=720, y=324, font="Arial", size=24, text_color=$ff0000, align=3) Subtitle("This is Anamorphic video", font="Arial", size=24, text_color=$ff0000, align=5) ShowFrameNumber(scroll=true, x=10, y=27, font="Arial", size=24, text_color=$ff0000) ShowTime(x=72, y=44, font="Arial", size=24, text_color=$ff0000) ShowSMPTE(fps=23.976, x=68, y=61, font="Arial", size=24, text_color=$ff0000)

In this case I make sure frame 86 is the first frame of my retained clip and so far it has worked..
