DVD->x264 resizing question.

[dimtim]

Hey I'd like to backup my dvd collection in x264 on my PC and watch them on my new LCD tv. My question is, when I encode a ripped dvd, do I want to resize it to a higher resolution than 720x480 or do I want to let the player do that? Would it be higher quality if I resized it when I encoded it?

Thanks
Tim

You would probably want to either just crop the black bars or crop + resize(smaller) and then use what ever zoom feature your player/TV has to watch it in the right AR. You will get more bits/quality out of the encoding if you resize(smaller) during the encoding. But than again what do I know.

Really the end result looks better if you resize it smaller? That seems counter intuitive to me.

The end result will usually not look better if you resize to a lower resolution, my preference is to leave the res as is, crop the border's and compress with x264 using crf 18-22 depending on the length/content of the movie.... action movie would get a lower crf *i prefer quality over size* and a drama/slow scene movie i would encode at a higher 21-22 crf *quality should stay very close to dvd but file size will be nice and low.

thanks for the reply, but wouldn't you want to resize up to make the quality better at higher resolutions (like on a 1080p tv). Isn't a resize filter applied during encoding better than one applied in real time?

Downsizing will help hide artifacts, but you also lose detail. You'd really have to try both methods and see which works best for you. I'd rather have detail and live with artifacts in even-color areas than lose some quality of image.

I'm going to facepalm so hard if this is really it.
It's going to leave a mark. A scar, even.
