Making picture quality better when scaled

[void.pointer]

Hi,

I'm new to VLC media player, so I do apologize if my question is simple and has already been covered already. I did some google searching before I posted to make sure I wasn't missing any obvious documentation.

When I watch an AVI file, I normally set VLC to fullscreen. When I do this, and when the motion picture's native resolution is smaller than that of my monitor's, then I get a very blocky looking picture. I can see the pixels pretty well. To me, this means there are no advanced filters being applied to the output.

I'm using Windows 7 x64 (Build 7201). I have the KLite Codec Pack installed. Would someone be so kind as to tell me how I can increase the quality of the video output? I would prefer the highest quality filter, since I have an overclocked Intel Core i7 on my system and I'm pretty sure I have the power to handle it.

Thanks.

This is a bug on Win7, probably due to the video drivers.

Sorry to say that this also happened on Windows XP x64 as well. I can't remember if this happened on Windows XP 32-bit.

Omitting any blame on Microsoft for this problem, is there anything I can try in the meantime?

I seem to get a better quality (larger) picture by setting the "scale=" value (eg set to 2 rather than the default of 1) in the output string to a higher figure.
It may help.

Would you mind being a bit more specific about where this option exists? Specific directions would be ideal.

Caveat again.. This only MAY help. VLC seems to work better, worse, differently on some hardware/OS configs than others. So some experimentation may yield benefits

I have found that VLC seems to work better in SOME cases with larger than default scale and screen sizes.
So..........
At the bottom of the "Stream Output" window there is a text box called " Generated stream output string"
From here you can modify or add to the values previously set by the choices you made above from their default.
Place your cursor in this box and scroll through to see and edit the entire output string
Egs. <scale=1> or <vcodec=WMV2> etc.
You could alter the specific size in pixels by defining the value of width .Eg add <width=640,> to the string

Experiment with these values and you may well see some improvement

So, by changing the output string you can optimise or customise VLC to suit your needs.

PS.. observe the syntax!!! don't forget the comma separators

Sorry but you're still not being specific enough.

You said to go to "Stream Output" and did not mention where that was, so I fumbled around and found it in Preferences >> Stream output (on the left, with advanced view). However, on this window I do not have a "generated stream output string". I only see "Default stream output chain" and "VLM configuration file", plus a few checkboxes.

I didn't say go to... The stream output window ( you are streaming are you not???) is the second window you will encounter when you have selected streaming from the file menu. It is the window where you will enter what type of stream output you require. The prev post refers to this window

Are you kidding me man? Are we even looking at the same program? And yes, you basically did tell me to go to the stream output window. This is getting frustrating! Nothing you say matches what I see or makes any sense.

I do not have a FILE menu in VLC Media Player. I have the following menus:

"Media", "Audio", "Video", "Playback", "Playlist", "Tools", "Help"

Am I streaming? I don't know. Depends on what you mean. If you mean to ask if I am streaming video across a network connection of some sort, no I'm not. These are local AVI files I'm playing. Again, I must ask, are we using the same program and same version? I'm using version 0.9.9

[Greg]

OK, apologies for my bad saying "file" rather than "media" menu

Yes, we are talking about the same program.

However...You are in the"Serving Streams" / "VLC stream-output (sout)" forum!!!! So I expected you to be posing a streaming related question.

I think you would be better off in the "VLC Media Player" section. See Board Index above

Try re posting there with as much background info as possible relating to your problem(s)

Thanks Greg, sorry for the mixup.
