Different DIVX codec, different output size.

[DonGallego28]

I changed my original post since I found the answer. I just analyzed to copies of files that I have where the video is basically the same but the file size is around 100 mb different. The larger file is encoded using XVID while the other file is encoded using DIVX 5.1. What's the best codec when considering size of the file? I'm looking for something in between. In this case, I prefer the 100mb smaller file as the quality is the same as hte other file.

Also it appears that x264 codec is giving me the best possible quality. Is there a drawback to using AVC over DIVX?

[poisondeathray]

AVC is not supported on most standalone players, DIVX/XVID have much more support

AVC takes up more CPU resources to encode and decode

Overall is just better to stick with DIVX or XVID? which version is better for encoding?

...I prefer the 100mb smaller file as the quality is the same...

I think you've answered your own question!

But you'll find that the difference in size ISN'T due to the encoders (DivX and XviD are pretty close to each other in that regard) ... they were just produced using different bitrate settings. Personally, I use the ASPECT utility for determining bitrates; enter the play time, aspect ratio (4:3, 16:9 or custom) & audio bitrate you commonly use - now enter the file size required & it'll give the video bitrate to use. Also, hit the AUTOSIZE button & it'll give you the framesize to use at that bitrate to keep "reasonable" visual quality. A small 350 MB encode probably won't produce HD screen resolutions!
