great quality rm/rmvb conversion

[zackwz]

I've tried to convert rm/rmvb files to avi in super, the converted file size is alright, but the quality is terrible compare to original. What settings or format or program should i use to convert so that the video quality is preserved?

Are you changing resolution ?
What codec are you encoding to ?
What bitrate are you using for video ?
What bitrate are you using for audio ?
What is more important - quality or size ?

If quality is the most important thing to you, ditch SUPER, and use avisynth to filter and resize before frameserving to virtualdub for econding. Frankly, I have never seen a real video file that wasn't already pretty flawed. SUPER doesn't do much i the way of clean up, and if you are resizing or using too low a bitrate, then all the horrible flaws inherent in real encoding will be made worse.

Yeah, quality is most important. I don't want to resize. I want it so that so if i open rm/rmvb file in realplayer and the converted one in media player, thay would look exactly the same, quality and size wise. Right now, i'm using divx+mp3. I heard xvid and h264 are better, but not sure how to go about with h264.

The chases of you converting it to another format at the same resolution and quality and filesize are probably not great. Every conversion carries the risk of some degradation when using lossy compression, as every encode throws away data, even when you use the same bitrates and parameters.

SUPER has the option for h.264 and also losslessly compressed via Huffyuv.

Ignoring size for the moment, try outputting to Huffyuv to see what the quality is. As Huffyuv is losslessly compressed, saving at the same resolution as the original should give you an indentical image. From there you can load it into virtualdub to save it using another codec over which you have more control.

rmvb is problematic.

In super, i think you have to resize to get it to better quality conversion.

Use strech it option. Set bitrate about 6000. Turn off de-interlace if not required. Check high quality.
