MP4 help

I have DVDs of TV show and I am going to put them into MP4 format and then put them on my Media player.

My player can connect to a TV if I want to watch them.

I want to use MP4 because it works with very Low bit rate to give great picture video.

To also save space on my media player I was going to bring the Frame Rate down.

I know NTSC TV is 30 fps so I was going to leave it as is.

But then I see that DVDs I think are working at 24 fps.

What am I not geting if a NTSC TV show is 30 fps and they put it on a DVD at 24 fps why does a DVD not look gidery or skipy?

Or do I have all this wrong?
 
I'd probably convert them to MKV, as this is a more widely used file container unless you want to play your videos on a PS3. For converting I'd recommend Handbrake or RipBot264 for encoding H264 video. Make sure you also use 2pass encoding.

What are the specs of the videos that you want to convert? (audio codec, video codec, bitrate etc.)

Cutting it down to 24 fps should be fine. Most TV's have a refresh rate of 60hz/100hz/200hz so it should still appear smooth.

I'm assuming that all of these videos are legal.

thanks but

They are VOB files that I take from my DVDs I have and put them on my media player.

They are NTSC 720x480
They are TV shows. The Simpsons and so on.

I was useing MP4 because I see you can use Low bit rate and get very good video picture they say.
 
DVDs in North America are 29.97 fps, the same as standard TV. The main reason to convert to 24 fps is to get better progressive video.

Movies and some TV shows are shot on film at 24 fps. To make suitable for TV, they have to pull up the video to 29.97 fps, interlaced. That is done by mixing the interlaced fields of the video. To go back to 24 fps progressive, you use 3:2 pulldown which hopefully gives you video similar to the original. It also deinterlaces with no quality loss.

PAL as used in Europe is easier to handle, going from 24 fps to 25 fps and back.

DVD is relatively low res.You could use plain mp4. When going to avi (Xvid) or mkv, you should make the video the final aspect ratio. All NTSC dvds are 720x480 regardless of the playing aspect. If the video is a fullscreen then your avi should be 4:3, widescreen 16:9. If you are unsure, you can get the playing aspect ratio from your player, Mediainfo or G-Spot. Over-fat or -skinny people are a sign you got it wrong.

Size and bitrate you will have to decide based on what you intend to show the video on, but there is no point in going overboard due to the dvd resolution.

Per previous threads, very widescreen 2.40:1 etc are usually 16:9 video with black bars top and bottom.
 
thanks but

Thanks for all the help.

One program I ues is WinFF but now I am having problems getting it to work/.

I put my VOB file in and set it to convert it to MP4 video size 640x480 bit rate 1000

Frame rate 30 video ratio 4:3

I have it set to output to desktop.

It does the convertion and when it is over nothing is on my desktop?

People say RipBot it a good free program but can I make changes to settings with it?

I like to have controle over things.
I did try Handbreak and does not work at all for me. Takes very very very long and never makes a file.
 
I don't normally use Handbrake but I have it installed. I tried it on a VOB file and it seemed to work OK. I didn't bother with many settings to try it out, just the video tab. I got output OK. What settings did you use? Did you check where the output was being saved? The default is the Handbrake folder I think.

There's no particular reason to go to 30fps if the original is 29.97. In Handbrake I left "same as source".
