Hi there, my name is Harm Weidmann and I'm new to this list as well to creating DVDs. My problem is as follows:
When creating a DVD from a series of jpeg images (720x576) I get severe flickering especially the fonts are flickering. When watching on my TFT everything is just fine but when I play the created DVD on a 50-60Hz television it gets pretty ugly... I "played" with several quality and interlacing options but did not manage to produce a useful result. Examples: "cat ./cm_output/seq0frame*.jpg | jpegtopnm -multiple | ppmtoy4m -F25:1 -I b -A 59:54 -L -S 420mpeg2 | mpeg2enc -f 8 -q 1 -I 0 -o ./xy.m2v" "mencoder mf://seq0frame*.jpg -mf w=720:h=576:fps=25:type=jpg -of mpeg -mpegopts format=dvd -ovc lavc -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=15:acodec=ac3 -o test_mencoder.m2v" "cat ./seq0frame*.jpg | jpegtopnm -multiple | ppmtoy4m -F25:1 -I b -A 59:54 -L -S 420mpeg2 | yuvmedianfilter -r 2 -R 2 -v 1 | mpeg2enc -f 8 -q 1 -I 1 -o ./xy.m2v" I also tried to alter the images with blurmotion filters or set the height to 1/2 and then reset it using bicubic... (Tips Google washed up). Again no success. Since I do not seem to make any progress in this matter I offer a 100$ reward for the one who can offer the best working solution to this problem. Conditions: You have to use this image: http://www.schenck.de/dvdimg/seq0frame0001.jpg and create a 1000 frame video from it. The generation of the DVD/ISO must be done by Linux tools like the examples I stated above. Important: The DVD has to run on 50/60Hz televisions without flickering! No sound needed just add silence. The one with the solution that provides the best (quality > performance) result will earn the 100$ //php5 script for creating 1000 images from the original one //just save the script to a file in a directory with the image and then //run it with: php5 <filename> //(I guess you all know but I try to maximize my odds) <? for($i=2;$i<=1001;$i++) { $shell = "cp ./seq0frame0001.jpg ./seq0frame"; $counter = $i/10; if($counter < 1) { $shell .= "000" . $i . ".jpg"; }elseif($counter < 10) { $shell .= "00" . $i . ".jpg"; }elseif($counter < 100){ $shell .= "0" . $i . ".jpg"; }elseif($counter < 1000) { $shell .= $i . ".jpg"; } exec($shell); } ?> Aside from the 100 bucks you get my appreciation would be really great (as my relief) Greetings Harm ------------------------------------------------------------------------- Take Surveys.
