DV Bitrate

[somja]

I am kinda new to this stuff...im wonderin what bitrate does an actual mini-dv record at..i have a canon zr30.

the reason i would like to know this is to determine at what bitrate i would need to encode at to have a lossless quality from my original.


thx in advance for all your help.

DV bitrate is 25Mbps, you are goung to get losses when encoding to mpeg, its inevitable, if you encode at a high enough bitrate though they will probrably not be noticable to you. Anyway max bitrate for DVD is only 9.8 Mbps.

[The village idiot]

If the original is very clean, then 6Mbps or higher is good. And as Craig said, max is 9.8Mbps. If you go too high, some of the cheaper players may have problems. Though this normally only shows up when used with mpeg audio and high bit rate video. If you can make it fit on one disk with 7Mbps, you should be fine all around.

is a bitrate of 5000 cutting it close to loosing alot of quality? cuz the video i have is quite large

You're going to make someone watch 2hrs of home movies ?

Sorry, I couldn't resist.

Assuming the sceens don't change much, can't you try a clip on a DVD RW and see if it is ok by you ?

I personally find my rotten camera work requires at least 6k. But no one ever made it thru 30min of my stuff. (zoom in, zoom out, nd on , nd off, pan left, pan right)

LOL. Be careful not to be the guy pulling out 6 hours of home video at every family gathering.

I don't know if you can compare to my videography when I've been drinking, though... the motion kindof makes people sick when they watch it

On that note, though, you can fit about 71 minutes of video at maximum bitrate video (if the audio is AC3 or mpeg - but be careful about using mpeg audio if you're on NTSC). If your movie is longer than that you tweak the settings, but if it's 2 hours it's time to start splitting it up onto two discs.

There are thousands of threads on the subject of encoding, but just a reminder if you don't already know: look into VBR for anything but maximum bitrate encoding.

Remember that the only real test of what's good enough is if you like the quality on the target device.

the video is ~90min...i was planning on using Studio 8 to encode into DVD format...but it does not have a VBR setting...what other program would u suggest in which i would get similar or better quality while using vbr and maybe a more compressed audio format?

TmpGenc, CCE, Mainconcept. You choose

[somja]

whcih one is best for VBR?

[bugster]

whcih one is best for VBR?

All have their strengths and waeknesses.

Tmpgenc, great quality output, fairly easy to use, cheap, Very Slow

CCE, great quality output, more difficlt to use, not so cheap, Fast

Mainconcept, good quality output, somewher between TmpGenc and CCE is useablity and speed, can't remember price.

IMHO

[somja]

where is the best AVI (Made from Studio 8) to DVD conversion guide for using CCE

[bugster]

Try the convert section over on your left. You might not find a guide that gives you precisley what you want, but there are sveral guides on avi to mpeg conversion, you should be able to find something to get you started.
