I am capturing from my camcorder using HuffyUV codec. I have been capturing at 480x576 but when I play it back on the PC the picture is tall and skinny.
I captured to this size because I'm using TMPG to make a PAL SVCD. After the encode the screen size is corrected. So this isn't such a problem but my question is -
Should I set the VirDub capture size to match the resolution of the source (the camera in this case) , or should I just stick with 480 or 720 x 576 ?
By capturing at the source's resolution, wouldn't this stop the computer trying to fill in the gaps to get the extra resolution ?
Thanks

There is no extra resolution. PAL SVCD is 480x576. If you capture at a greater resolution than that, the video will have to be scaled down before encode. This can be a quality improvement, but it's not necessary.
After the MPEG encode, the video is still 480x576, but displayed as 768x576 (to get a 4:3 aspect ratio -- AFAIK, AVI doesn't support specifying an aspect ratio). |
