Can you mix different encoding rates in a same DVD?

[jgandara]

A few months ago I encoded a few files at CBR 6000 - MPEG2 for a Hi8 vide camera. Now I have a DV camera and I'm thinking on encoding CBR 6500. Can I use 2 different encoded files in the same DVD?

Is there info on suggestions for bitrate encoding? also rates for different sources like VHS, Hi8, DV...

Thx

yes you can mix ... no issues ..

use the highest bitrate that you can and can fit the project on the disk -- no mater the source ..

i'm looking a guide to compare different bitrates and how to use them depending on the source, do you know if there is one out there. I can't find one.

The bitrate calculator (in TOOLS on the left) will help you figure out how much you can fit.

Well, it's not like I wan to burn just one DVD. I take one cassete every 2 months, so as soon as I finish it, I edit the video and create small video files (each file is a chapter). So I have some folders with enough video files to fit in a DVD. They are home videos, the camera I'm using a Sony miniDV DCR-TRV33 camcorder.

So i'm trying to decide what is the best bitrate to encode the video. I want good quality for this source, but i don't want the highest bitrate. I'm thinking around 6500, so from 6500 to 7000 is it a big difference in quality?

Do small 3-5 minute tests on each setting and determine what setting is best - for you. :c)

Every source is different. That's why there can never be a guide that says "use this bitsetting for this video".

That is the only thing you need to know!!! There IS a guide that fits all. Use the hightest bitrate that you can.

Your beating a dead horse,
if they didn't get it the first or second time,
I don't think they'll get it the third time

A somewhat related question:

Can you mix different framerates (NTSC vs. PAL) on the same DVD ?

Let's say I have a number of MPG2 files, some 25 fps, some 30 fps (or 29,97 fps) Can I mix and match these and author a DVD ? It would be an ideal way of making "collection" DVDs of music videos from various sources for example.

YES, I know can convert or "re-encode "all clips to the same framrate.

I see that when a DVD spins up on my standalone DVD player, it indicates either PAL or NTSC on the display, so I assume it's a "global" setting on each DVD, not per clip, chapter, track etc.

There was another thread, pretty recently, asking that. You may be able to find it with a good search.

From memory - which is shaky after only one cup of coffee so far :c), it is outside of "specs" wherever those elusive specs are. :c)

Someone did a test (out of curiosity) and managed it, but it is highly unlikely it would be compatible with many players. (It may not have even been tried on a player, perhaps PC only. I don't remember if they specified that.)

In accordance with the dvd spec, it can't be done BUT you can mix 16x9 content and 4:3 content on a disc for corresponding television systems - ntsc and pal, respectively.

It may play on some rebel players, but for the most part I think the obstacles outweigh the advantages unless your disc is not going out to a large audience. if it works, screw it 8)

Feel free to correct me if you find otherwise

If you keep them on seperate tracks, won't be a problem with some tweeking.

It is an advance topic. You need first to learn how to make a simply DVD.

In short terms, I made DVDs which have mpeg 1 and 2 files, PAL and NTSC clips, with all the DVD legal framesizes. I used TMPGenc Author and DVDPatcher. Parts of this DVD is playable on all standalones and parts are playable only to few standalones....
Older standalones had the most problems, the new ones (after 2002) rarelly had problems

The GOP stracture is also a problem, many standalones can handle everything than not a proper GOP. Unfortunatelly....
