E ------------------------------------------------------------------------>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>---------------------------------------------------- Here is the ratio table for real movies (OK did play fine, NOTOK did give me 'playback not available): 640 352 1.81818181818182 OK 608 336 1.80952380952381 OK 608 336 1.80952380952381 OK 640 352 1.81818181818182 OK 720 464 1.55172413793103 OK 624 272 2.29411764705882 NOTOK 720 576 1.25 NOTOK 448 256 1.75 NOTOK and here i have created a few PNGs with GIMP and converted them to a video with: ffmpeg -loop 1 -framerate 1 -i 640x400.png -c:v libxvid -t 10 640x400.avi 640 300 2.13333333333333 640 310 2.06451612903226 640 320 2 640 330 1.93939393939394 640 340 1.88235294117647 641 350 1.83142857142857 642 360 1.78333333333333 643 370 1.73783783783784 644 380 1.69473684210526 645 390 1.65384615384615 646 400 1.615 647 410 1.57804878048781 all of the myself generated videos did play OK. the ratio range was from 2.133 to 1.578 so i guess it will not be ratio issue and maybe the watermark is still in the game. what do you think?
