Predict the size of a completed MPEG

SPLATTYMATTY · Post by **SPLATTYMATTY** » Mon Jul 31, 2006 7:52 pm

Is there a way to predict how big the end video file will be? Im using VideoStudio8. I use the multi-trim option to get the bits of video that i want from a larger file, throw in some JPG piccies, add in a bit of music, and the final MPEG ends up at > 4gb, which wont fit onto my DVD. My elapsed time for the film just created is about 80 minutes, but when i create the video file it creates a 5gb file. Or is there a way to compress this so that it can still be played on any DVD player?

Try DVD Shrink.

It's all a matter of choosing the correct bitrate. From the bitrate (bits per second) you can scale-up to gigabytes per hour.

A Bitrate Calculator is very handy!

If you are using Dolby audio, a video-bitrate of 6000kbps (=6mbps) will give you about 90 minutes on a (single layer) DVD.

Higher bitrate = higher quality = more disc space = lower compression = less playing time.

Lower bitrate = lower quality = less disc space = higher compression = more playing time.

DVD Shrink fits your video onto the DVD, no need for calculation. It's nice to have around.

Please view the article in our FAQ section
What bit rate should I use?

Hi SPLATTYMATTY

As mentioned earlier a bit rate calculator is what is needed. With a bit of experience you will just guestimate and get it right.
In addition try this http://dvd-hq.info/Calculator.html there is a bit more reading and info here.

As a guide:-
8000 kbps will give 60 minutes
6000 kbps—90 minutes
4000 kbps---120 minutes

Also read Bit Rates and File Sizes from the link below.

For your project at 80 minutes use a bitrate of 6000. This will fit with bits to spare.

a wealth of information, for which I thank you all! i had created my video files using 8000 kpbs with the PAL DVD movie template, but will now redo changing the rate to 6000 kpbs. My project is 77 minutes long, includes 34 jpg files playing for 4 seconds each and using 40mbs and 1 audio file of 4mbs playing for about 5 mins. Please remind me never, ever to offer to video someones wedding again...........
