Title: Unwanted jumps in Burning Ship zoom sequence Post by: youhn on June 06, 2014, 01:10:40 PM I've finally made a video with Kalles Fraktaler, Mplayer (to extract images), ImageMagick (to scale back to 720px), Mencoder (part of Mplayer, to make a x264 video) under Wine in Linux!
https://www.youtube.com/watch?v=xhm5OCa3lQc But somehow Youtube changed to resolution back to 360px ... :-\ And after I use the Kalles Fraktaler keyframemovie.exe, it builds a serie of film_xx.avi video ... but there are jumps. This is obvious when looking at the zoom value in the top left of the video. Anyone with the same problem? Maybe even a solution for the jumps? What is the best way to upload a high quality fractal zoom video to youtube? Now it looks all blocky and blurry.

Some movie editors make the joints visible when merging the avi files, chillheimer had that problem, but e.g. Microsoft movie maker does not make any visible joints. Instead it looks to me that not all the avi files were merged, in order. It looks like it is only every second. That can explain those jumps, with no squares or any other errors. YouTube unfortunately destroys the movies, and to get a good result it must be taken into consideration. This means not to fast zoom speed in dense areas and not too fast color cycling, for example. Title: Re: Unwanted jumps in Burning Ship zoom sequence Post by: youhn on June 12, 2014, 02:54:09 PM Youtube still trashes the quality, but I have found a way to prevent the jumps. By decreasing the "Frames per movie" when using the Key Frames Movie Maker under Wine in Linux. Maybe something to do with max file storage or memory consumption of the uncompressed raw vids.
