File>Project Properties>Edit>Compression

Hi folks

I've got a simple question about something in Video Studio 10 Plus.

When I go to File>Project Properties>Edit>Compression, under "Media Type", I get this slide bar with "Speed" on one end and "Quality" on the other end. When I slid it all the way to the "Quality" end, the number that appears next to the slide bar is "100". When I go all the way to the "Speed" end, the number that appears is "0".

What does all these mean?

Thanks!

Hi

Afaik it’s the amount of effort the encoder puts into rendering/creating a video file.

70% being the optimum setting.

I use the default setting.

Others will give you a more technical answer.

Like Trevor, I tend to leave that slider alone. Essentially, 100% means the program will do the maximum analysis it can to produce the best quality, but it will be a much slower process. On the other hand, if you want the process to be faster and are less worried about quality, you slide it the other way. But if you drop it too far, the process will be very fast, but the quality will be terrible. The default setting to me represents good final quality in an acceptable period of time.

Thank you everyone!

My movie is 15 minutes long, and I've just upgraded to a dual core Athlon-X2 with 2gb of DDR ram. Just for the sake of experimentation, I will slide it to "100" for "best quality" and see how long that takes!

Will post my result when I'm done!

Hi folks

I just rendered a AVI video clip of the length 00:1:56:23 on a 100% quality compression.

It took my PC this long to do it: 00:22:20:51 !

The saving grace is, the resulting product, when played on my old 24" Sony DRC television, is visibly much much better!

Hi
How long on 70 %

Am I correct in assuming 00:1:56:23 is 1 minute-56 seconds and it took over 22 minutes to render.

Wow that’s a long long time.

Render times depend on many factors

Your pc
What you are rendering (the original project/file properties)
What you are creating (the final render properties)
What your project contains (effects and transitions.)

Even so 10+ times the run time is quite slow.

Hi Trevor

Your reading of the times is correct.

I had only 2 crossfade transitions, with one 1 second black colour block in front and one behind the clip to accomodate the transitions. My PC is Athlon-X2 (dual core) running on Asus M2N-SLI Deluxe Motherboard, with 2gb DDR RAM. So yes, the process was darn slow!

But I love the quality. My AVI video clip was taken on my little Canon Ixus 40 digital camera and taken on the fly, so there wasn't a lot of time to compose my scenes properly. I'm doing this presentation for a friend in Australia, and I'm trying to get the best quality DVD out of clips I've taken without forethought. So I have to sacrifice sleep even if I stay up all night!
