Movie Quality on QVGA
I understand that QVGA has far less pixels than VGA. My question is how does this affect the quality of movies and games shown on QVGA, do you get used to it or are you constantly thinking "This is awful". Some comparison pics would be nice

Thanks!

it should be perfectly acceptable.

VGA quality does allow better resolution, sharper pictures, but that isn't to say video on QVGA is worthless.

I've been happy, even on my X50v, running FairUse in such a way that it makes 250 MB movies with 80kps sound.

Is there pixelation from time to time? Yes. Does it seriously hamper my enjoyment of the movie? No.

Give it a shot and see what you think. If you want higher quality, keep bumping up the size.

There are a lot of other reasons to get an X50V but the X30H is a very good machine too

You say that movies on your x50v are occasionally pixelated, if i was to run the same movie, encoded at the same rate on a x30H QVGA would I see a diffrence in quality? Would an X30H be perfectly fine for playing stuff like the Simpsons and the occasional feature length movie?

Thanks Again

I watched movies and TV shows ALL THE TIME on my x30H, there's no problem with it.

The only problem maybe the battery life. But my fully charged x30H last me the whole movies without problem (ie. over 2hrs)

Thanks Mr Ding, you have really helped make my mind up!

What about games, do they perform well and look good on the x30H QVGA?

Some of you are confusing terms.

If you are encoding an entire movie at 250 meg, you will see artifacts from lossy compression. If you encoded the same movie at 1 gig, you would likely not see any.

The VGA screen can display more detail with better clarity. But if it's worth paying more for, only you can decide.

I picked up my x50v for $359. For me, it was well worth it just for the better display (I had two x5's previously).

Also keep in mind the x50v has a hardware decoding card, meaning your video card in the x50v decodes the video - so your going to see not just better picture, but better frame rates - even if your cpu is throttled back to 200mhz.

movie clarity is all dependent upon how high of a bitrate you use to encode it just like mp3s if you encode at too low a bitrate your movie will look like crap if you encode at too high a bitrate your pda will have trouble playing it there is a lot of room in the middle to play around with the screen size on most pdas are pretty close to the same 3.5 inches seeing how the screen is smaller than most screens you are used to watching video on the qvga is more than adequate for its screen size most of my movies are mpeg and come in at about 300-400 megs per hour but they are high quality and high fidelity stereo sound and I have an x5 that plays them fine with pocket tv I also tried some divx and wmv videos and they take less space but the picture quality is not as good for me although it is not bad just not as good as my mpegs
most of my movies are encoded at 30fps but if you want to save space and put less strain on your cpu then 15fps is just fine fluid motion can be reproduced at 15fps but you dont want to go below 15fps but in the end its all up to you what you deem is acceptable to you plus a x30 is supposed to do video better than my x5 Me myself could not imagine watching a 2 hr movie that was only 250meg it must look like crap from my tinkering experience but that is just my opinion.

Yeah, I know. Therefore, logically, the pixelation on a X50v would be worse than on a X30 at the same level of compression.

I don't need "perfect" movies, but I need enough clarity that the pixelation doesn't bug me.

You're going to need to try various settings to see what you need.

Some folks need to compress a movie to 700 MB to be happy...not me. I'd rather carry 3 full movies in that 700 MB space (well, 750) than one gigantic movie.

It's all in how you encode them. Take a look at some of the stuff at ppcvidz.com and you'll see what I mean. Those flicks look good.

Check out bigds63's encoding guides to get results like that yourself.

i think you mention getting your x50 for $359 in about 90% of your posts!

As for the original question, I have a x50 mid and the picture quality is great! No problems at all. My movies are usually around 380 mb.
