Based on your reply, I should not set the field threshold to 480 because the captured video is interlaced, correct?

If this is correct, then the advice on Lord Smurf's website is not correct.

North

Yeah you can leave it at 288 (or set it to 240). If you have set it to 480, compression will suffer but you don't really break the video (imho).

But why 712 pixel? Not 720?

bas

edit: hmm I went to this "Lord Smurf's" page and yeah, the advice starts correctly but in the end reverses what it wanted to tell :)
Just leave it at 240/288 according to what you are usually processing and you cannot go wrong. The 480/576 setting is only there for people that process full d1 progressive video all day long, as you can save quite a bit of hdd space this way.
Don't forget: changing the setting often with patch versions <0.2.4 is quite bothersome, as they don't store the setting in the file.

I wonder if I can attach the 0.2.5 patch to this post somehow or so...

bas,

Thanks. The added explanation clears this up for me!

As for why 712x480, please see "Determining the capture window of a capture card" at:

http://www.arachnotron.nl/videocap/s...ure_area2.html

I have a BT878-based capture card and use the BTwincap driver.

See also this recent thread:

http://forum.doom9.org/showthread.ph...h+capture+card

Wilbert and others are working on a revision to the capture guide that I believe will cover this.

I actually read that after editing my post...
It has been a long time since I captured anything and back then nobody cared about aspect ratios, one could be happy if they understood lurker's guide. It seems that has changed in the meantime :)

Somehting nags me about that guide, though. The measurement dvdr.. I know standalone dvd players that shift the image to the left or right if you select rgb compared to svideo/composite. So I wonder how reliable this method is.

So is it possible to have file attachments here? I kind of have no website for the latest patch version.

(who always liked avi_io that could keep perfect sync for video and audio no matter how many frames on dropped)

bas,

See the following post in the Capturing Video forum:

Perhaps this will help.

@bastel

This is of-topic, so I will be brief

Since you determine the distance *between two vertical lines* it does not matter if your DVD has shifted the pic. You only determine the width of the window, not it's offset. (I originally intended to include that too, but had to take that out again exactly because of the reason you mention.)

If you have any further questions, just bump this thread.

@Arachnotron,

Do you ever get to stop being an "Absolute Beginner"?

Arachnotron · 19th May 2004, 09:58

nope, I just find more complicated ways to ruin them...

vispgraedde · 13th June 2004, 07:09

Since doom9 STILL link to this broken version of the codec I have to yet again request that it is removed, or FIXED, or PUT UP A WARNING THAT IT CAN NOT COMPRESS RGB.

It can still decode old RGB huffy's so the problem is with 2.2.0 and compressing RGB. Sizes of these "RGB" huffy's are much smaller than they are supposed to be. Not equal to the YUY2 huffies... But about the same size... As if the R channel is compressed as Y and GB as UV (only getting partial data since those are of lesser resolution), and later when this data is being decoded, you get access violations because the decoder expects more data than is actually available.

I don't know exactly how the source got barfed up and I don't have time to diff sources just to find out.

How hard can it be to replace a link on the download page? Or add a note? Or how about someone actually FIX the problem?

@Sh0dan: It's been around 5 months since you said you would look at it ASAP... have you really been that busy?

numlock · 13th June 2004, 21:09

Question: If I undestand it correctly te latest HUFFYUV version is broken when using RGB comprtession. BUt is it safe for YUY2, cause that's the only one I use ?

Thx

vispgraedde · 14th June 2004, 07:16

YUY2 is safe afaik.

Why don't you send Doom9 a pm asking to replace it with v2.1.1 CCE patch 0.2.5?

North2Polaris · 20th June 2004, 16:17

Doom9 has replaced version 2.2.0 on the download page with:

http://www.doom9.org/Soft21/Codecs/h...-patch_025.zip

I sent a PM to Doom9 not long ago about the concern raised in this thread and he sent the following response:

Hi

I'm aware of that but I haven't managed to find a "safe" version.. that's why I'm still stuck at the latest bugged version. I even asked sh0dan but he couldn't help me either. If you know a place to get a working version please let me know.

Doom9

There is a lot of energy that goes into maintaining a site like this and much work goes on behind the scenes.

Backwoods · 14th December 2004, 06:38

I'd still like to try out the 2.2.0 version, does anyone have a copy on their HDD still?

ftp://141.53.8.34/pub/video/codecs/huffyuv-2.2.0.zip
ftp://194.126.98.42/windows/codecs/huffyuv_220.zip

The first download contains just the dll and the inf. The second download contains all the original release files. Sorry it's taken 14 months for someone to reply to your post. lol

Backwoods · 4th February 2006, 02:25

Better late than never. Thanks!

PhillipWyllie · 6th February 2006, 15:01

Does anybody know what the latest version is?

v2.1.1 CCE patch 0.2.5 - this should be available from doom9's download page. You should not use another version. If you want a more efficient codec you might try the Lagarith codec.

Longinus · 7th February 2006, 08:48

Version 2.2.0 is safe for YUV2... I use it a lot.
When I need RGB, I use the Lagarith codec like Zarxrax said.

PhillipWyllie · 7th February 2006, 12:37

What's the patch for? Oh I use 2.2.0 for YUY2 and have no probs.

keys · 7th February 2006, 14:20

Interesting to know about 'Lagarith' Zarxrax - many thanks.
