Shrinking file size

[ktkia]

Hi,

I LOVE this software but I have not made many videos before. Is there a file format I should chose for a smaller file size? I have 8 minutes of video in the vpj and it is converting to 123 mb avi. Can I make the file size smaller? I tried changing number of frames per second and frame size but that didn't change a thing, so before I make myself crazy, I thought I would just ask here.

Thanks in advance.

You need to lower the bitrate of your file. The bitrate affects the file size of your video output as well as its quality. The lower the bitrate, the smaller the file size but the output quality will also be lowered. Click the Encoder Options button or the Bitrate Settings button after pressing the Build button in order to change the bitrates.

 

You can use a bitrate calculator to predict the output size of your file based on your audio and video bitrates and the total running time of your video.

now that is useful!

 

I'm rather insistant on VideoPad being able to estimate video size as a future feature.. so we'll see.

Unless you have some particular reason to be working in AVI, (which is generally uncompressed), why not work instead in mpg2 if that is available to you. I try to obtain the best image-quality possible and generally use a variable sampling-rate based upon a scan-rate of 9800, with 'two-stage' renders, the first to tee-up the optimum quality for the second which is the actual 'render' itself. I have usually been so satisfied with the outcomes that I have no wish to change to Hi-Def. If you change to mpg2, and your original material is 'avi', (I'm assuming DV-AVI input), your original footage remains unchanged and of 'camcorder' quality. The process, then, is non-destructive, and if you don't like the outcomes from the change, the original footage is not compromised. At all costs, don't over-write your original footage.
