don't be mad; they won't give you an answer because they think it would just be a waste of their time to answer your question.

if you want better quality, raise the bitrate; resolution has nothing to do with the quality of the video(that i know of)

tj,

people like you aren't welcome here.


You got the replies you needed and broke rule 12 once more - you should really check them out again.

(I could write which other rules you broke as well:
1) Read up before asking! There are tons of guides, FAQs and each forum has a dedicated Q&A thread with additional info.
1a) Use the search function before posting. Chances are your question has already been answered.
2) Respect the netiquette: Lurk and get to know the forum before you post.
4) Be nice to each other and respect the moderator. Profanity and insults will not be tolerated. If you have a problem with another member turn to the respective moderator and if the moderator can't help you send a private message to Doom9.
9) Use a title that describes the content of your post. Don't use all caps or special characters to draw attention.
12) How NOT to post on this forum:
5 minutes after your initial post you reply to your own post writing something like "Why is nobody helping me? I'm sure you know the answer".
Once somebody replies to your thread but doesn't give you exactly the answer you've been expecting you insult them.
Do not ask "what's best" because this question cannot be answered objectively. Each and everyone has their own view about what's best in a certain area. The best is what works best for you!

How wrong you are, my young apprentice! We have the forum rules for several reasons, but most important is:
we are a QUALITY board. If you want instant crap, head over to vcdhelp.com or visit the divx.com forums. There you can be that ignorant and nobody will care.

Ah - but then again, look at the QUALITY of the answers you get with such questions... reminds me of your answer here, isn't really scientifically based and explained, right? See, that's not usual here: we don't answer yes or no, we elaborate things and explain them.

Ah anyways, I feel like you won't take this answer as it is, but as an insult or something, and are going to start a flame thread (your initial sentence in the above mail is very promising), so I don't think it's necessary to give further explanations in that matter.

and a little mathematical trivia. Quality is related to how many bits each frame of the video gets, the more bits the better it looks. Thus raising the bitrate will lead to a quality improvement.
On the othe hand if you increase the resolution and keep the bitrate you'll have less bits for each frame of your video which will obviously lead to a lower quality.
Now you may be thinking, resizing the video does decrease the quality. This is partially correct and strongly depends on the resize filter being used. Filters like the bilinear one have a tendency to smooth out the picture (as in kill some details) so you'll have a quality decrease. But using a high quality filter (bicubic at neutral or sharp setting for instance) the quality loss is almost always not perceptible to the human eye. Also, human perception is really different from person to person (that's why we have rule12.. it's different for everybody so asking what's best is like looking for a needle in a hay of straw and since people can usually not resolve their differences in such matters it degrades into a flameware) so it may well be that even using the bilinear filter you may not be able to see the loss in sharpness.
