I made a list of guides I'd like to do on improving video quality (and not messing it up) and I think there were 13 things on the list. Not sure if aspect ratio is on it but it will be now.NerdWithNoLifehttp://www.blogger.com/profile/03415464690421707385noreply@blogger.comtag:blogger.com,1999:blog-6133785540334951464.post-28108201062569209532009-01-03T09:39:00.000-08:002009-01-03T09:39:00.000-08:00I enjoyed reading this one. It would be great if you post in the future WHAT are those things you should take care when encoding a video (in order not mess it up). <BR/><BR/>I basically just take care of a couple of basic things like (assuming video is going to be shown in a progressive-scan device):<BR/><BR/>- do I need to deinterlace footage? or is it already progressive...<BR/>- do I need to crop black bars?<BR/>- am I'm going to down/upscale footage? <BR/>- do I need to take care of PAR when rescaling?<BR/>- do I need to boost the audio (volume wise)<BR/>- the order in which I applied the above operations<BR/><BR/>I use mencoder (along with its ffmpeg libraries) to encode most of my videos but I haven't really worked with the specifics of every codec...<BR/><BR/>All the best,<BR/>JorgeJorgenoreply@blogger.comtag:blogger.com,1999:blog-6133785540334951464.post-35939747281799991212009-01-02T10:47:00.000-08:002009-01-02T10:47:00.000-08:00Nice post!
