Ensure it’s the same number of seconds as before.Ĭall it “stage 2.mp4”.
GIFSICLE OVERLAY GIF MOVIE
Don’t worry about the “My Movie 1” metadata, it won’t survive the next step. The video should be animated as normal, but with your censor bars in place.Įxport the new video from iMovie by clicking “Share -> File…”.
This is how it should look (excuse the blur):Ĭlick the play and rewind buttons a couple of times. The bars should now be in place over the image. Drag the overlay around and drag its corner to fill the screen. 1 Go back to “video overlay settings” and you’ll find that your censor bars are visible, but they’re the wrong size. Change the “style” from “Ken Burns” to “Fit”. Nothing is showing up yet, and that’s fine.Ĭlick the “cropping” button in the video preview area. Change the effect type to “Swap”, and the duration to 0s. Up the top right, in the video preview area, click the “video overlay settings” button and change the overlay type to “Picture in Picture” (mine defaulted to “Cutaway”). If the image’s duration is longer than the video, scroll right, grab the right end of the image, and resize it until it snaps to the video’s duration.Ĭlick the image in the timeline view.
png from “My Media” to above the video (not on top), and release it when a green ‘➕’ shows up. Grab the desired end of the video in the timeline view and drag it to resize it. If you’ve recorded too much video, then now’s the time to cut that off. Drag your “censor bars.png” into “My Media” too. Open iMovie, and drag in your “stage 1.mov” file from QuickTime. The PNG should be the same dimensions (NxM pixels) as the video, and should be entirely transparent except for the censor bars. Hide the base layer and export this as a PNG. Load in one frame of the video (I actually did this by taking a screenshot and importing that).Ĭreate a second layer, and ensure it’s transparent. If you don’t need censor bars, skip to Convert. mov format, which isn’t super convenient for sharing. If you want your gif to loop cleanly, make sure you get enough footage for that.
GIFSICLE OVERLAY GIF HOW TO
Figure out how to record the video you want, and record it. Handbrake ( ) to remove the letterboxing.iMovie (free from the App Store) to add them to the video.I also wanted to censor parts of the image. However, gifsicle may still be better as it is a specialized tool just for gif images.I recently wanted to record my screen and turn it into an animated gif, on macOS. \( pic3.gif +dither -remap colormap.gif \) \( pic2.gif +dither -remap colormap.gif \) \( pic1.gif +dither -remap colormap.gif \) +append +dither -colors 256 -unique-colors colormap.gif
You can also add -layers optimize to potentially further reduce the file size. You can just append the 3 input gifs and get the unique colors for the color map image.
In ImageMagick, it would be best to find one common set of colors and use -remap color_map_image to convert all the input images to the same set of colors. But each might use different sets of colors. Since your images are Gifs, they are already quantized to 256 colors or less. Each of your images needs to be quantized to 256 colors or less.
GIFSICLE OVERLAY GIF CODE
Its quantization code is accurate but slow. ImageMagick is a general purpose image processor and does not optimize gifs as well. Gifsicle does special optimization just for gif.
