Bitrate help

This is just a Q/A about VOB File Bitrate so I thought this would be a good place to ask.

If I made a VOB File and it had no Action it it can I make the Bitrate 700 bps and will the Video look good?

I have Home Movies that my Camera takes as .MOD Files.

And I am going to convert them to VOB Files so I can work with them and do things to them.

I was just thinking how Low is to Low for a VOB File Bitrate before it will look bad?

If you have the .mod files used (exclusively for standard definition video files) by JVC, Panasonic and Canon in some models of digital camcorders, get SDcopy.exe, a link here.
This utility converts MOD files giving them more conventional MPG extension, and, more importantly, sets "widescreen" flag in the file header.
Then you can work with them and do things to them in Movie Studio.

That's kind of your call.

It's not unreasonably low. (I assume you mean 7.000 Mbps and not 700 bps.) So if you're happy with the results, that's all that matters.

After all, your output DVD can't be higher quality than the original video. That's just not possible, even if you up the bit rate.

Hard to tell what he's after. 7Mbps is plenty high for most uses, and isn't really anything to even bother asking about. It's a thoroughly normal value.

700 bps, which is what was written, is absurdly ridiculously low. I doubt you'd even find an encoder that would allow a number that low.

700Kbps (assuming that space is supposed to be a K) is in the queasy blotchy web video range from the early quarter-frame sized days, probably not even something you'd want to watch on youtube now.

7000bps (assuming that space is supposed to be a 0) would be pretty bad, probably ok for encoding animated icons, but not for video.

700Mbps (assuming that space is supposed to be an M) is insanely high and would fill up your hard drive quickly and be nearly impossible to play back.

700 Kbps is perfectly adequate for stills (no pan, zoom, or fades) due to the nature of interframe compression, such as MPEG-2 and AVC/h264. In fact, some h264 encoders process stills around 250 Kbps maximum bitrate at 720p resolution.

With minimal motion (talking head against a static background for instance), Jerry has demonstrated that 200 Kbps AVC is "almost" adequate in some controlled cases. Corresponding bitrate would be quite a bit higher with MPEG-2, maybe triple that number.
