hhheelloooo..... still need a answer to this one

[BJ_M]

the question makes not a lot of sense - so the answer is no

[DJRumpy]

Exactly. Try actually asking a question that goes somewhere . A few suggstions to get you on your way:

What encoder are you using?
Where is your source material from? (DVD, CAM, VHS, etc)
What resolution is your source AVI?
Is size a consideration (is your movie over 2 hours long)?

Leebear gave nice examples of what ratio aspect would look like on tv:

The larger display will make any errors or flaws in the video that much more obvious, but does not dictate any specific procedural changes as mandatory. You may need to re-adjust color settings, etc. for best picture, as for any new display.

IF it is a widescreen TV, then you can get involved in all sorts of aspect ratio conversions and options, dependent also on disk format and DVD player.

thanks RaleighNC & Nelson37 thts what i was looking for.... right now i have a regular 36 inch and do notice when i play something on my portable dvd player, 27inch then my 36 inch...... i do start seeing more things evident than in the smaller sets........ also i plain on getting a 50 inch soon and want to correct this problem now b4 i get the bigger set....also i understand " Aspect Ratio " but other problems are more the little bit of pixlation i see and frame slowage i see on the bigger tv (which i thought tht really couldnt happen on dvd)..... most of my .avi files is off the web so i have to work with what i got and i use tmpgenc 2.58 as a coverter

mol3000,

if your source avi's are mainly DivX files that you've downloaded, the quality you end up with is not going to be that great. Even if you convert it to DVD format, the quality of the final result is limited by the quality of the DivX source. The DivX codec achieves the (relatively) small files it generates by 'throwing away' a lot of data in the encoding process, and you can't get this data back.

If what's bothering you is being able to see 'blockiness' on the bigger screen, you might want to try using a different encoder. TMPGEnc is undoubtedly a great encoder, but some people say that there are others which give a smoother, less blocky output. For MPEG1 (VCD) at least, there are a few threads on this forum dicussing TMPGEnc's sharp but blocky output against - say - Panasonic's slightly blurred but more 'natural looking' mpg's.

You might want to have a look at the comparison of different encoders and formats on this site.

The only problem is that not many MPEG2 encoders are free.

cheers,

It's not the size that matters,it's how you use it.

I disagree. Today's DivX files can closely match the source in most respects, and exceed quality from older DVD's. I have some DVD's, that look like broadcast. It's amazing what they'll charge for some of these, as even I could have done them better .

Back to the point...Even after a second conversion from DivX back to MPEG, the final project can look excellent. I have a 57" HDTV, so compression artifacts are VERY evident.

Mol: If you source files are DIVX from the internet, chances are their source was DVD. When you get these, there's little you can do to improve the quality. The only additional filtering I do, is to apply a 2D cleaner, or a temporal smoother, but only if I notice compression artifacts. Pay special attention to high contrast areas. You'll find more artifacts there, and also watch the high motion scenes for bitnoise. The 2-D filter seems to handle these better than the temporal smoother. The TemporalSmoother handles general noise better. Usually you won't see these from a good rip. If you do notice some, then apply a light filter. Don't over do it, or you'll lose detail. Both of these filters are available in VitualDub, and AVISynth.

If you use AVISynth, use the optimized 2-d cleaner, with the standard settings. I'm at work right now, but if you want, I will post the script for it when I get home, as it requires you to load an additional script to configure all of the settings.

I prefer to use the temporal smoother in MPEG2DEC. You access it via AVISynth. The defaults also work well:

LoadPlugin("MPEG2DEC.DLL")
AviSource("youravihere.avi")
TemporalSmoother(2,3)

Of course, you'll need the latest version of MPEG2DEC for this one to work (see the Tools sectino on the left).
