Thanks a lot. here is my feedback. First quick question: --export_asr 2 -Z 720x480 -Z 720x346 -Y -68,0,-66,0 --export_asr 3 Would the sequence of the options significant as ffmpeg? i.e., I want to confirm that the order of export_asr and -Z doesn't matter. Now about the examples, Example 2, which uses -Z 720x480 option to change the frame size from 640x480 to 720x480, wiki says the DAR of 4:3 will remain unchanged. Is this has something to do with the black magic behind the -Z option? because 640:480 is not equals to 720:480, if I do this in ffmpeg, the result will be distorted. Example 3, ,----- | As mentioned above, *aspect ratios* cannot be stored in AVI files `----- I guess the *aspect ratios* here you meant PAR, correct? Still Example 3, I guess the output frame size of 1024x576 will be the value that movie player such as mplayer or vlc use when play the movie on pc. correct? and that'll be the size you get if you do a still image snapshot, correct? Example 6. ,----- | you have a 16:9 DVD containing a 720x576 MPEG2 stream as in Example 4, and | you want to display it on a device that has a 640x480 resolution with a PAR | of 1:1 (and therefore a DAR of 4:3). `----- That (intended device) is for most LCD televisions and monitors, since they have a PAR of 1:1. How about CRT monitors, televisions, and DVD players? Further, I guess that you forgot to put the --export_asr 2 there in the command. thanks again -- Tong (remove underscore(s) to reply) http://xpt.sf.net/techdocs/ http://xpt.sf.net/tools/
