Member Rogier Tuinte Posted June 12, 2012 Member Report Share Posted June 12, 2012 I work a lot with loop-videobackgrounds for company presentations. This time I use a projection 5760 x 1080 pix (3x HD). And I rendered the loop content in 3 HD mpeg-2 video with 25 fps (30sec long). I used a control cue with "jump to". It runs very smoothly but always when it loops, it stutters! Also when the video starts at play. So what I did is, I made a composition and added the 3 mpegs. Then I created a task and imported the composition (Time at 2 sec on the timeline) with a opacity fade in. Added a pause-marker and set the composition on "free running" and "looping". This solved the looping problem perfectly. Only when I start the task it stutters several times during the first 1 - 2 seconds. Hopefully anyone can tell me how to solve this problem. Thanx in advance.

Neil Stratton Posted June 12, 2012 Report Share Posted June 12, 2012 Hi Rogier: What bit rate are the videos rendered at ? Do they loop when played through a media player, not Watchout? Can you post the video details from GSpot or MediaInfo? Neil S 0 Quote Link to comment Share on other sites More sharing options...
Member Rogier Tuinte Posted June 15, 2012 Author Member Report Share Posted June 15, 2012 Hello Neil, The mpeg loops smooth in VLC player (mac), also in the Wathout-composition. Once it plays, there is no problem. Only the beginning from play it stutters several times and the 3 Mpeg's do not play sync at the start. I'd like to make a smooth fade-in for the loop-background, of course without the stuttering.

Neil Stratton Posted June 19, 2012 Report Share Posted June 19, 2012 Hi Rogier-comparing these stats to those of a similar video currently running on my system the only two differences I can see are: 1.This video is not progressive 2.My renders read as High@High for the format profile.Are these elementary stream? If you wish I can test on my system to see if the problem reoccurs. thanks Neil 0 Quote Link to comment Share on other sites More sharing options...
