Jeff Mottle Posted June 21, 2011 Share Posted June 21, 2011 Hey guys, This has been driving me nuts for years, but this year it seems to have gotten worse. I'm finishing up the editing of the videos for the 3dawards ceremony in a few weeks and am doing some pan and scan on some still images, but once rendered the moves across the images are very jumpy. Almost as though I am watching a movie at 5 frames a second. It's always been a problem, but for some reason this year it's unwatchable. The images are quite big (5000 x 7000) so that's the only big difference. I'm rendering the final to an MP4 H.264 at 1280 x 720, VBR 2 pass target of 4 Mbps. Any ideas why this is happening and how to smooth out the playback/rendering? Cheers, Jeff Link to comment Share on other sites More sharing options...
Devin Johnston Posted June 21, 2011 Share Posted June 21, 2011 Are you exporting with deinterlacing turned on or off? Link to comment Share on other sites More sharing options...
Jeff Mottle Posted June 21, 2011 Author Share Posted June 21, 2011 Are you exporting with deinterlacing turned on or off? It's all progressive footage so I have it turned off. Link to comment Share on other sites More sharing options...
Devin Johnston Posted June 21, 2011 Share Posted June 21, 2011 Jeff do you have CS3, I had to revert back to it because CS5 was so screwy. Link to comment Share on other sites More sharing options...
Jeff Mottle Posted June 21, 2011 Author Share Posted June 21, 2011 Jeff do you have CS3, I had to revert back to it because CS5 was so screwy. I do, but it did this with CS3 too, just not as bad. I re-rendered with WMV and it was significantly better, but not gone entirely, so I'm thinking it has something to do with a codec setting. Perhaps it's a keyframe issue or a frame rate. I rendered all of these at 24p to match most of the films that were submitted this way. Link to comment Share on other sites More sharing options...
Devin Johnston Posted June 21, 2011 Share Posted June 21, 2011 I just did a test with a high rez images panning across the screen at 720p and everything was smooth. I exported as a .wmv so maybe that's it. Link to comment Share on other sites More sharing options...
Jeff Mottle Posted June 21, 2011 Author Share Posted June 21, 2011 Would be curious to find out why now as it has to be Mp4 to stream online later. Will keep experimenting here I guess. Thanks for testing on your end. Link to comment Share on other sites More sharing options...
