Conversion Size Differences


Deaks
 Share

Question

I have been trying to convert my DVD collection into H.264 with Best Quality and the output file when I convert one at a time is 2GB - for a standard TV Show, if I grab 10 Episodes and then convert them with the same settings they all come out at about 450MB. Can someone please explain to me why the size difference and how to keep a standard size output weather I am converting 1 or converting 10 shows?

I am very confused as to why this is happening, I would have thought that the same video file would output the same size no matter how many videos are converted at one time.

What are yoiu using to convert the DVDs? Do you have the application set to fit to disc? Whatever application you are using is trying to make them all fit so that the bitrate is probably much reduced (as is the quality).

 

You have t tell us just what you are trying to do and how. Before we can help more. What are you trying to convert the files?

I am using Roxio Creator 2010, Copy and Convert, I wish to place the files onto a TB HDD for access by WD TV Plus. I can leave them as VOB files but the kids and wife get confussed. So I want to save them as Mpeg-4 HD1080. I tell it to convert to H.264 at HD1080 and the size issue is the result. I cannot find a fit to disc option within copy and convert.

VOB doesn't sound like hidef to me so why are you converting to 1080? You will not gain any quality or resolution in the conversion. Hidef files are bigger - period. Now if you just want MP4, why not just convert to standard definition MP4?

 

Open Video Copy & Convert

Click the Movie button and select the video_ts folder

select the movie on the right and click OK

This adds the entire movie in the left column

 

On the right choose PS3 which defaults to MPEG 4, 720x480

Quality at highest

Click the big green button

 

Adjust quality if you still need smaller file.

By the way even though the TV shows may be the same length in time, the video files may not be the same length. This has to do with the nature of how video is compressed which is based on motion and how much motion from frame to frame. If one episode is sports with fast motion, it would probably be larger than an episode with lots of scenes with less motion. 450MB doesn't sound large to me at all especially if the VOBs were GBs.
