Encoded file is larger yet lower quality?

post #1 of 9
Thread Starter 
I ripped my dvd and encoded it using mp4/avc. The original file.vob is 1gb, but the encoded file is 2.19gb with slightly lower quality. I thought h.264 is the best file format for high quality and high compression ratio. How come my file is even larger than the original and lower quality? What do manufacturers use to fit high quality/small video on dvd? At least the encoded video should be the same size as the original. What software can I use to encode high quality/small video file? I am currently using avs video converter.

Are you only converting one vob file, or is it a whole folder, example: VIDEO_TS. Either way,i would recommend downloading Handbrake and using it. It does a great job, very fast, and easy to use.

www.handbrake.fr

Good luck!

Did you use H264 in a avi container? The you resize it? Remember it can't improve on quality. So making it bigger by resizing it your going to get a poor outcome. I use H264/mp4 normally.

I am converting one .vob file at a time. I used mp4/avc in avs video converter. I am complaining that the converted file is bigger than the original yet with lower quality. Is it possible to make the file smaller than the original yet with decent quality?

As Wesker suggested, use HandBrake. It's powered by x264, the gold standard for H.264 encoding, and make DVD ripping a very easy task.

You have heard wrong my friend, try it and see for yourself.

I use it for all my dvd back ups and i use mkv container with a x264 codac using constant quality at 67% or RF17. Gets me close to dvd quality but half the size.

In simple laymans terms, you took a 5GB+ DVD and ripped and compressed it to ~1GB. This is where your quality went bad.

Then you took your inferiror VOB, chewed it up, swallowed it, and regurgitated an MP4. This also affected quality, simply by re-encoding.

Re-encoding, of any kind, usually has some drawback to it. About the only exception is when going from HD resolutions to SD resolutions. There is enough data present to make a very nice final product. Compare a divx ripped from a Blu-Ray to a divx ripped from a DVD. Both may have the same file size but the Blu-Ray rip will probably look better.

I would investigate a different method of ripping and perhaps consider another method of playback of said rips. Whatever will result in the least amount of molestation of your files.

I didn't rip a 5GB+ dvd and compressed it to ~1GB. It is a tv shows so there are multiple episodes on one dvd. I simply copy one epsiode(one 1gb .vob file) over to my computer and convert it to mp4. the file size is twice the original but lower quality.
