motion blur?

[chakotay2]

I switched from VCD to burning SVCD because of blur when there was alot of motion on the screen. It really hasn't improved. Is this a issue while converting, or do I burn differently? The files look high quality when played in TMPG preview...but have lot's of motion blur during high movement / action... Thanks.

Hi!

Are you using Constant Quality (CQ) or even Constant Bitrate (CBR) (even worse)?
Because if you are, I sugest that you try 2Pass Variable Bitrate (VBR) instead. It takes a little longer to encode, but it´s worth it...

If you use CBR you get a constant bitrate in the whole movie, but in VBR you get a average bitrate (that you choose to fit your CDs). That means that you get a low bitrate when there is no need for more, wich makes room for a high bitrate (up to 2520) when there is much movements in the movie.
I resantly encoded a movie at VBR 1600 (two 80min CDs) and got a stunning result.

Hope it helps.
Regards!

Yes, I am using Constant Bitrate. When using VBR though, you say you used VBR 1600. How do you control the size of your file when using this method? I don't want to have to use 4-5 or more CD's per movie... 2-3 is bad enough....

I have had great success using "Automatic VBR". It yields the typical 60 minutes (or a little more) of video per CD-R, with no blurring problems. I also have "Motion Search Precision" set at "Normal".

[chakotay2]

I have motion search precision set at high when I encode... do you have any idea what niz_se is saying about automatic VBR being set at a specific rate so you can control the size? I thought with the 2 pass like he is saying you are stuck with the size it gives you.

I have no idea what "Niz_se" means. I, will however, reiterate that I have consistently obtained excellent results with the following and suggest you try:

Let us know of your success ;>}

Hi! again...

I have actually never tested Automatic VBR, but I should try to explain about the 2Pass Variable Bitrate (VBR).

In the Constant Quality (CQ) you also have variable bitrate, but here you put in the wanted quality and the file-size depends on the movie.

In the 2Pass Variable Bitrate you put in the AVERAGE bitrate, and you can calculate the file-size on that. I use FitCD to calculate the bitrate. This way I can fill my CDs to the limit and get the best bitrate possible for two CDs. For an example, with an average bitrate at 1600kbps you can put in about two hours on two 80min CDs... Remember, the bitrate will go below 1600 and also above, constantly, but the AVERAGE bitrate will still be 1600.

So, I hope I cleared up som questions....Test it!
Now I think I´m going to make a test with Automatic VBR...

Regards!
And HAPPY NEW YEAR!!!

What have you found to be a good setting for min, max and average bitrate using 2 pass?

Thanks,

Also, where can I find fitCD? The link I have found to it is:

http://members.tripod.de/fitcd/

and it looks like it is down.

Thanks,

Well, I just checked that url and it´s up again...

The Min and Max settings I never touch. Many DVD-players cant´t work with bitrates above 2520 anyway (so I heard...).

The Average setting, is up to you. Do you want high quality or few discs...? I usually use two discs (80mins) coz I´m used to change disc once from all my VCDs. But I try not to use more than two. To get the most of your discs you really nead a birate calculator, FitCD is just one.

Okay, will give it a shot... I have Bitrate Calc...looks like it does the same basic thing...

Thanks!
