Bit Rate help

thebrain900 wrote on 1/9/2009, 4:13 PM

I use Movie Studio 8.0 and need some help with understanding Bit Rates.

When I go to Rander As and then Pick MPEG-1 Templeatte I then go to Customize Tab.

In here under the Video Tab you can keep a Check Mark in Constant Bit Rate or pick one from the Dropdown List.

I go to pick my own Bit Rate and the lowest is 1,140,000 Bits.

Am I right that the Higher I make the Bit Rate the More information the Video will have and the igger the Video File will be???

And the Lower the Bit Rate the less Information the Video will have and the Smaller the Video File will be???

Yes, that's correct. However, as we have told you many times before, mpeg1 is the wrong format to be exporting, it's old, and it doesn't have enough quality. Try WMV instead. For the same amount of bitrate, you will get better quality, because the format is more optimized.

I am only using MPEG-1 for low Res output like for YouTube anyway.

MPEG-1 lets me lower the Bit Rate so I get more Video for a small File Size.

Is there a way to ajust an MPEG-2 Bit Rate???

You cannot customize the mpeg2 templates in VMS8.

For YouTube, I always go for the wmv format. It allows any customization, bitrate included. For long movies, I set the bitrate at 1000, for short movies, I set it at 3000.

And, at lower bitrates, you get better quality with .wmv than with mpeg1.

I was useing WMV for exporting Video to for You Tube but one thing I did not understand??

When it came to the Audio you can pick your FREQ 44.1 Hz I get this then instead of saying 16 Bit it would say 96 kbs or 192 kbs oir something likie this.

CD Audio is 44.1 Hz at 16 Bit Audio and I could not find that.

Can you explain???

44.1KHz and 16 bit are the format of the audio.

96Kbps or 192Kbps are the bitrate used for compression

They don't have any direct relation to each other. When using uncompressed formats such as .wav then the sample rate (frequency) and bit depth determine the file size. When using compressed formats like MP3/MPG and WMA/WMV then the bitrate determines the file size.

I just got a program called Rip N Burn DVDs

And I use it to convert files to diferant Formats did anyone here of this if it is any good??
