Conversion to mpg problem
Posted: 2009-11-30T06:36:28-07:00
Dear,
First of all, thanks for this great piece of software.
However I see a problem. I am converting to mpg´s for a while now with IM6.4.0 Now I saw that for certain files you lose a lot of colour information of a file.
I have tried converting to 6.5.8 and All the colours are there! Isn´t that great????
Unfortunatly, none of my applications accept the newly generated mpg files (for example irfanview). Quicktime does not see any problem Though.
I have looked a little bit into MPEG specs and I have found that an MPEG file needs to end (in hex format) in 00 00 00 01b. IM6.4.0 does this.
IM6.5.8 converts to mpg and the file ends like this: ac 0f ff ff ff ff ... and this stuffing continous
This difference tells me that the conversion does not create an MPEG according to the specifications of MPEG
convert.exe -resize 1280x720 -quality 100 test.jp test.mpg
