MP4 or RMVB?

[mooshimuushi]

Hi everyone,

I'm quite new here and I hope everyone here don't mind me asking a few questions

I have these 2 videos. One is an MP4 and the other is an RMVB. I used MediaInfo to have a look at their stats, but I can't tell which one is better.
I did notice the resolution difference and the small video bit-rate difference but I still needed some help to know which on is better.

Second Question down below

Here are the 2 codes/stats for the Videos.

Here is the MP4:

I was wondering which one is better, because I want to watch these on the PS3. I don't mind converting RMVB to MP4 again to watch it on the PS3.
But I was wondering as well. If I convert RMVB to a MP4 format for the PS3. Would it have better video quality then the other MP4? Because of the original resolution? Or would the Other MP4 have a better resolution (if) I convert it.

Thank you in advance~

You cannot tell from looking at stats alone. They don't convey how it was encoded (e.g. one may have had prefilters). The only way to tell is to examine them

[mooshimuushi]

Well if that's true, then I guess the RMVB is bad.
It's kind of pixelated.



And the MP4 isn't so bad.



But what if I convert the RMVB. Would it have a better quality then the MP4?

[Ai Haibara]

No. You can't regain quality. You can attempt to make it look better with filters and such, but more or less, it's not going to get any better than it already is. Worse, re-encoding generally takes a quality hit.

[mooshimuushi]

So, in conclusion out of these 2 Mp4 is better then RMVB?

What about overall?
Which is better? MP4 or RMVB? o.o?

[Ai Haibara]

I'd say you'd be the best judge of that, if you mean whether or not your MP4s are better than your RMVBs. The image from the MP4 does look a lot better than the RMVB, but that still may not be enough to determine which of the two encodes you'd prefer.

Overall? Both containers allow for high-quality video, I believe. It all depends on how it was encoded (and the source which it was encoded from).

I should note, though, that RealMedia formats are proprietary, and it may be a hassle to find converters to work with them as well as you'd prefer, all of the time. And, as you know, the PS3 doesn't play RMVBs. But just having a file in an MP4 container isn't a guarantee the PS3 will like it, either.

[mooshimuushi]

It all depends on how it was encoded (and the source which it was encoded from).

What do you mean by, "On how it was encoded (and the source which it was encoded from)" ?

Also yes that is true, not all MP4 files are accepted by the PS3. Especially the audio...=.=" (Been having trouble with it lately ;D)

I guess it is to which I choose.
But can I hear your opinions? I'm still new with the video community, so I don't know as much.

::EDIT::
I converted the RMVB to MP4 so that it can be played...but it was...
HORRIBLE!

I guess my choice is MP4!

Thank you all for your help

[Ai Haibara]

Well, I usually prefer working with MKV and AVI containers - but remember, it all depends upon the quality of the video/audio used to create the initial encode, so that even the highly-compressed RMVB can be decent, if you create it from excellent-quality video and audio sources. (That's what I meant - for example, a video's going to look a LOT better if you encode using high-definition sources, rather than a low-quality FLV from YouTube, a 160x120 capture from an old TV card, etc.)

Also, you want to avoid converting as much as possible, because as you noticed, you'll usually get a decrease in quality. It can be even worse for RMVB, as the converters may not support it fully or properly.

[mooshimuushi]

Ahh I get it now...(I think).

So a good video and audio source is from a DVD right?
That's where the original work is.

Hmm, I see. I seeeee.

Thank you a lot Ai Haibara for your help!
I've learnt many things from just this tiny thread
Thank you.
