Can someone explain the quality loss, Divx to DVD???

[ChrisS95TA]

I have read hundreds of pages on converting. I am using divx AVI files, combining them yusing virtual dub then using WinAVI to make the VIDEO_TS folder to burn in NERO. It alll work good but when converting with WinAVI the quality of the video goes down alot even though the inital AVI is 500 MB for a less than 2 hour video. Is it my choice of video converter? Thanks in advance for any help.

Think about it.

You are taking a lossy file and converting it to a dvd, which causes it to lose more quality.

It is no different than taking a 4x6 picture and blowing it up to poster size.

It will look like garbage.

It is usually better to just buy the movie on dvd.

Well, most are not even a movie....some are fights, others are military videos. The quality when playing through windows media player is great (at full screen to a TV through my TV-OUT) while after converting and burning to play on a DVD player (and also blown up to 4.3 GB) the video in noticably less quality. I still do not understand after your post

Notice the phrase blown up - That is your answer.

You can not take what is not there and insert it and make it better.

Hello,

Bazooka's right - you can't magically make it look better by converting it to dvd.

(and also blown up to 4.3 GB) the video in noticably less quality

Probably a bad conversion with the bitrate settings. It would be ideal to get the ORIGINAL source video to encode properly. You're messing around with the actual picture images and if it's small compared to the final target size it won't look better it will look worse.

Also - MEGABYTES aren't whats important it's BITRATE and RESOLUTION.

The main DVD RESOLUTIONS (NTSC):

720x480
704x480
352x480
320x240 (with 48khz audio - ie vcd video with dvd audio rate)

If you stretch the picture out past its original size it will look very bad. If you encode it to the nearest size available for dvd standards then you will have it look CLOSER to the original but never EXACT. The only way to ensure a clean dvd encode is to use the ORIGINAL source and encode it to the proper bitrate ONCE. It will never look BETTER than the original you can just hope for SIMILAR results....
