[Solved] Video playback not working as it should
I am writing out of desperation.
I have created an animated screensaver using Adobe After Effect for our internal company screen savers. The video uses lots of slow motion animation so it is created at 60fps full HD. I then uses Adobe Media encoder to export to H.264 .mp4 file. The video plays back perfectly on my Mac and on PC in quicktime and Windows Media Player. When I import the file into iScreensaver I am getting some weird jerky transitions especially on slow movements.
I have tried exporting from Quicktime Pro 7 as I read on one of your posts that this could be an issue. I tried exporting the video on Mac and PC. I tried creating the screensaver on the Mac and PC version of iScreensaver. I tried exporting at 30fps. I tried a smaller file size. I tried .mp4, .mov and .avi file types. I have pretty much tried everything that I can think of and it still never plays back smoothly.
I can't afford to waste any more time trying to get this to work so I was wondering, if I send you the uncompressed video file, can you export it for me and send me the working screensaver file? We are happy to pay for this service if it can be done for less than $200. All we want is for the screensaver file to play back as smoothly as it does in Media Player or Quicktime - it's not a difficult ask but I have been extremely frustrated in trying to get this to do what it is supposed to do.
