bitrate too high, files too big

[sdsumike619]

I'm authoring a DVD using Vegas 4.0 for editing and DVD Workshop 2 for the authoring. I have a video divided up into 20 regions and I render each region to use in DVDWS2. The total length of the video is 1:33:23.14
I rendered the videos using the bitrate calculator's suggestion. And I'm using ac-3 for the audio tracks. When I go to write an .iso file in DVDWS2, it tells me that the bitrates are too high and need to be adjusted - why is this? And what is the lowest bitrate I can use but still have the video be of good quality so I can make this thing fit onto a DVD5. I don't have any other video except for two 35 sec motion buttons on the main menu, the other menus are all still images... any help is greatly appreciated!

can anyone help me? My image file turned out to be 5.2gb...I thought that a standard DVD5 DVD-R can fit two hours of video, why is the file so large?

Lower your bitrate.

[sdsumike619]

how low can I take the bitrate where the viewer won't notice the quality change yet still fit on the DVD?

you could give us some information on the current bitrate settings you are using
and whether it's CBR,VBR, CQ or whatever

[sdsumike619]

I don't even know, I think it's 6000, VBR..I'm just going to lower it to 5000 and see what the heck happens i guess

Ok not sure if DVDWS2 gives all the VBR bitrate settings
you are supposed to have 3 max,avg,min but I have seen some apps that only have 1 VBR setting
I don't use DVDWS2 so I can't tell you - however if it doesn't support multipass VBR then consider something else for your encoding
Mainconcept, TMPEG, CCE basic, etc...

Generally if there is not too much motion/action go for
Min 1000 AVG 4500 MAX 7000
Multipass VBR

more action bump up the average to maybe 5000 or 5500 and the max to 8000 but I find I only need this for really high motion stuff

have a play around and go from there - encode only a short section say 5 minute chunk and see what looks good in your eyes

[sdsumike619]

8000?? an hour and a half movie will never fit at 8000, that much i know for sure

[D_Knife]

Did you actually read my post???
8000 is the MAX for hi motion movies
you would only get to this for a couple of seconds mostly
and by hi-motion I would suggest an action movie or similar (matrix stuff like that)

most movies fit well into
min 1000 avg 4500 max 7000

DVD Video standard:
Up to 9.8 Mbit/sec MPEG2 or up to 1.856 MBit/sec MPEG1 video
dont forget about the audio bitrate
