mpg format is poorer quality??

[hldE]

I want to ask that is it that mpg format video is poorer quality than .avi video? I downloaded a music video file n the quality is near DVD quality..at least i feel that it is very clear n sharp but when i use tmpgenc to encode it into mpg format, the output seems poorer compared to the avi version..anyone can explain that? One more thing is that may i know how to change the size of the video to 16:9? i use tmpgenc wizard n select 16:9 but the output always give me another size e.g 1:1 or 4:3..pls help..

No. They're just different. The encode is likely being done at low quality and/or with improper settings.

I can make an AVI look worse than MPEG and vice versa.

So what i need to do to make the output clearer n sharper? At least (what goes in, what comes out)..i try everyting..like using highest quality but the output always give me the same quality..thanz

What are your EXACT settings in tmpgenc

You want to work with DVD's only. You can't take an encoded AVI and convert it to MPEG and expect it to look better. It nearly always looks worse because it's a 3rd generation encoding. That's 1 for the DVD (it's not lossless), 2 for the AVI and 3 for the final MPEG.

Also, what resolution was the original. You want to avoid expanding the original to fit. That is, if the original was 320x240, you defintaely do not want to resize it to 720x480. Each pixel will look 2x as big and it will look like a 320x240 at full screen. It would look better if you letterboxed it, but that's annoying. Stretching your source video to fit a resolution is the most common cause for 'bad' looking video.

You also have to take a non-interlaced avi and make it interlaced for the DVD. Futhermore, you have to deal with the framerate. 'Hopefully' the source is 29.97 fps ( it won't be 23.97, music videos aren't shot on film). If it's 15 or 20 fps, then you have other issues.

I found using that encoding program produced not that great quality. You should try using Cinema Craft Encoder to encode your video. Mpeg is a poorer quality but it mainly comes down to what encoder you use. Some are better than others and vice versa. I find Cinema Craft Encoder produces a better video than Tempgenc, plus it is a faster encoder than the other. Plus you can add more filters to the encoder to produce a better quality picture, but expect a longer waitng time for the finished product.
