Sony YUV codec?

mbelli wrote on 6/19/2004, 6:08 AM

Can someone explain what exactly this codec is used for?

I'm trying to find the best uncompressed output from Vegas. I've installed Huffyuv Codec so I suppose I can go with that or uncompressed, but I also noticed this Sony YUV codec.

I like creating DVDs and web media (Quicktime, Windows Media) from an uncompressed Vegas file. This gives me the advantage of being able to use the file with Canopus Procoder, Squeeze or CCE. I'm just not sure if the Sony YUV codec would be good for this.

Also, I've noticed that both uncompressed and Huffyuv give me very "flat " files that I have to increase in contrast before encoding to MPEG or whatever. But the Sony YUV seems perfect, similar in gamma/contrast to a plain Vegas NTSC DV file.

As well, I've ran into file size problems with uncompressed files from Vegas, which I don't seem to get with Huffuv, wonder if the Sony YUV has file size constraints as well.

I don't like using Vegas to produde MPEG for DVD, VCD or go from Vegas to Windows Media/Quicktime. I'd rather work with an extrernal program so I have more control and can crop, boost brightness/contrast or add more filters. This is why I'm trying to find the best way to go uncompressed out of Vegas.

Any help appreciated.

What of this statement can't you accomplish right in Vegas to begin with? Vegas can crop, adjust brightness and contrast, and has close to a zillion filters. All of them are parameterized and adjustable with a very fine grade of control. What are you trying to do that you can't do in Vegas?

I'm more confused over the "I'm trying to find the best way to go uncompressed out of Vegas so I want to use Huffy etc" comment.
Huffman, Sony YUV are both compressed formats.
Not to mention as Kelly said, all those parameters of adjustment are quite easily controlled in Vegas at the event, track, or project levels in addition to dropping filters on at the Media Pool.

This is true, Spot. The best uncompressed output from Vegas is ... uncompressed. If it's that important, don't compress it. In that case, there are no codec choices because there are no codecs involved.

First, I'm kind of new to Vegas, and don't have the time at the moment to play around. I really know Sorenson Squeeze and Canopus Procoder, which have been my standard for delivering web movies, so I prefer to work with them for final delivery.

As well, From my initial short Vegas tests, and it could be my own inexperience with Vegas, I get slightly better Quicktime videos going through Squeeze (using Sorenson 3 pro) then I can get with from Vegas. Not only that, there are many convenience settings in Squeeze/Procoder that I just prefer working with them for Web delivery .

As I post this, I've just finished some tests and was very impressed with Vegas DV codec. Outstanding! Imported into Procoder or Squeeze the results are terrific.

However, I still wanted some info on going uncompressed out of Vegas. The tests I've just completed with the Sony YUV codec are not very good, I though it was uncompressed, but I guess it's not.

The results from the Vegas DV codec itself are so impressive, I might just leave it at that. However, back to if I wanted to output uncompressed, Huffy on my system is better as I get a file lenth problem with straight uncompressed from Vegas, I think I can only do 9-minutes or so.

As well, both Huffy and uncompressed produce "flat" looking video, which needs to be boosted (increase contrast) to look right when I import it into Squeeze, Vegas DV codec is dead on.

Also, is Huffy not uncompressed? I thought it was.

Again, it's not a question of what can't I do with Vegas that I can do with other software. This is all about personal preferance. In regards to working with Web media from Real, to Quicktime to Windows Media, I've always had a preference to use an other more specialized program like Cleaner, Squeeze or Procoder -- there are reasons why these programs exist, guys .

It compresses 2:1, but it can work lossless.

Another way for you could be using a frameserver to feed the Procoder. Would give you uncompressed frames without big data-space waste.

That would be awesome, any quick tips on how to get that going with Vegas, or a frameserver program you know that works well with Vegas?

A frameserver plugin for Vegas is offered at debugmode.com. I know it works great with Vegas and TmpgEnc but I never tested it with Procoder. Give it a try. If you use Vegas 5 don't miss that patch needed. It is given on the same web page.

Huffyuv can be configured to be 100% lossless. It compresses only to save space. It does not in any way degrade the image. (This is dependent on hw you configure it, of course. YOu must be sure it does not change color spaces, etc.)

I use Huffyuv 2.1.1 (Not 2.2.0) for all my uncompressed needs. In this case "uncompressed" be not lossy-compressed.

I also use Huffyuv 2.1.1 but new to Vegas, is there anyway you can post your Huffyuv settings that you use in Vegas.

I'm unclear on the color space options.

The main reason these exist is because other NLEs do a crap job of sending media out to the web in particular. Outside of QT, none of the other tools encode web media as well as Vegas. On the other side, until recently no one made a good built-in mpeg encoder either. Vegas has very nice mpeg encoding, and it's internal. Most other NLE's still don't.
Anyway, the YUV is a 4:2:2 codec in Vegas.
