I'm trying to reduce the resolution of some raw video using avconv. The output must keep the same raw video format, as at a later stage I need to load it into another program which is extremely picky and won't accept any other kind of input. Now, I have tried doing
avconv -i myvideo.avi -s 88x72 -vcodec rawvideo myvideo-small.avi
An this produces the reduced video alright, but it seems like the format is not exactly the same one. avconv says that the read input is
Stream #0.0: Video: rawvideo, pal8, 352x288, 30 fps, 30 tbr, 30 tbn
while the produced output is
Stream #0.0: Video: rawvideo, yuv420p, 88x72, q=2-31, 200 kb/s, 30 tbn, 30 tbc
Even though both are rawvideo, input is "pal8" and output is "yuv420p". I'm not aware of the differences between these two formats, but I need my output to retain the exactly same format as the input. How can this be done?
