MPEG II Video Quality drops using Any Video Converter...

[Spoilerone]

Hello everybody!

Please take a look at the attached videos.

The first one is a sample xvid, 1280 x 720, that looks rather decent, though not extremely good.

Now, check the second. The same video, converted with Any Video Converter, MPEG II 1920x1080, 1800 Bitrate (at least that's what it says on the screen). Horrible, horrible conversion job. Or is this normal, expected behavior for MPEG II at such a resolution?

Actually, I intended to test this tool to convert some home videos from a Sony camera to be viewed at full screen on a Sony Bravia TV with USB input. The user manual for the TV says the only thing it is capable of playing natively is either MPEG I or II, with no chance automatic rescaling (it will always show the video at its native resolution).

Am I just screwed with this? Or are there better ways to do what I intended to do with my videos? What do you think?

Insufficient bit rate for MPeg2. Shall I assume this is 29.97p? Start at 8 Mb/s (8000 Kb/s) then test down.

What is the camera? I don't know of any camera that saves as xvid. Start with the original file.

2500 kbps is way too low for 29.97 fps MPEG 2 at 1920x1080. Try several times higher.

Your TV should show any 16:9 flagged MPEG file full screen. There's no reason to go to 1920x1080.

I was referring to the 1280x720p/29.97 fps xvid source when I said 8000 Kb/s.

A crappy result would be absolutely normal from taking an Xvid, UPsizing it, then giving it a ridiculously low bitrate. In fact, if the goal was to create crap, this is a pretty good way to achieve it.

Loose the upsize, give it some decent bitrate, and it should be only slightly worse than the original.

@edDV: Oh no no nonono... that was just a test video. My camera does not output xvid files (duh). Matter of fact, my camera does only 3gp (it's a photo camera that can also record videos). Screen resolution is waaay waaay smaller than the test video.

Also, 8000 kbps doesnt seem to appear as an option in AVC, at least using the MPEG II converter at such resolution.

@jagabo: Unfortunately, my TV does not seem to do that. A 720p video (like this test video) is shown at 2/3 screen size. I even asked a supposed "expert" about it... this particular TV model does not scale videos at full screen, at all.

Oh well, guess I should be buying a DVD player, after all. Thanks!

We could help more if you identified the camera and TV by model number.

I've never seen a Sony Bravia TV that did not scale 1280x720p to full screen.

Weird. In any case, you can convert to MPG with a 1920x1080 frame size. Just use a high enough bitrate. Or use an encoder that has the ability to encode in constant quality mode. The encoder will use whatever bitrate is necessary at each frame to deliver the quality you ask for.

Very well. My TV is a Sony Bravia, model KLV-40BX400. The Sony page for it is: http://www.sony-asia.com/product/klv-40bx400 .

As for the camera, I don't have it with me right now, but I'll post the model later.

Many thanks for your interest in this issue, btw!
