"HuffYUV revisited" 2.2.0 released

I have been doing some modifications of HuffYUV to make it better for my NLE-tasks, and I thought some of you might have some use for it too.

Here is the changelist:
* Added "Reduced resolution". This will save your file in HALF the orginal resolution, and upscale the video on the fly. Lossy, but very fast!
* HuffYUV is now storing interlaced mode in the AVI-file. Now interlaced files are properly decoded!
* Added MMX optimized YUV -> RGB conversion routines.
* HuffYUV will now suggest to store RGB32 (RGB with alpha), even if it is disabled. Alpha information will however be removed when on.
* HuffYUV should now support all resolutions flawlessly. Do however not that it is not recommended to use a resolution that isn't divideable by 8, when using Reduced Resolution, and YUY2 naturally must med divideable by 2.


It _should_ be 100% backwards compatible with HuffYUV 2.1.1, but HuffYUV 2.1.1 will not be able to decode all 2.2.0 created files.

Get it from: http://cultact-server.novi.dk/kpo/huffyuv/huffyuv.html.

Please report any problems, and I'll see if I can help.

I am really glad you are taking a look at huffy, so thanks very much for the work.

I tried a little testing. Both VDub and my Winfast capture software crashed hard when I tried to use the reduced resolution checkbox. Any suggestions? The test resolutions were 720x480 and 640x480. I tried many different settings but that did not seem to make a difference.

That fixed it, thanks

Sh0dan, the only thing I am wondering about is the reduced stuff seems to look pretty bad. By that I mean the letters of a title are scored through with lines as if missing every other line. Since I know you are a bit of a perfectionist, I don't think I am seeing what you intended.

It's supposed to be ugly.

When I do editing and compositing/postprocessing speed is more important than quality, since I'm dealing with some quite highres material. So it matter quite a bit that huffyuv is four times as fast at delivering the material. And when I'm done editing, I simply replace the files with full-resolution ones and hit "render".

This is why it's for NLE, and not capturing.

I almost missed this thread

Sh0dan could you include the changes of 0.2.3 (download section of Doom9). It's a fix for appending two huffyuv clips.

I'll do a diff and see what the changes are. Apparently I've missed the 0.2.3 update.

Neat!
Why did you hide this in the NLE-forum, where I hardly ever look? (First time today, to be precise ^^ )

Great to see my favorite codec is still being improved! Many thanks!!

My apologies if I ask something I should have known, but I noticed the 0.2.3 version in the download section has now been replaced by the 2.2.0 version. Does this mean the changes in the 0.2.3 version were superseeded by this one? Or are there now two versions?

This new huffyuv is crashing any program that tries to access the files created with it. Files were created with default settings. Virtualdubmod reports the following:

Crash context:
An out-of-bounds memory access (access violation) occurred in module 'huffyuv'...

...while decompressing video frame 0 with "Huffyuv v2.2.0" [biCompression=55594648] (VideoSource.cpp:1823).

Here is a sample clip that I encoded. It is 480x480 resolution.
http://zarxrax.kicks-ass.net/extra/147.avi
The small size makes me wonder if there is even actually encoded the frames, as most of my files encoded with the old huffyuv were about 10x larger.
Is it possible to extract even a single frame of video from this? The content is semi-important, but I can't remember exactly *what* the content was, so I'm unable to recapture it.

I can't help you with the huffyuv problem, but I can get a frame from it using the viewer from Total Commander. Here is s acreendump, so you know at least what was in it . The avi won't play on my machine either.

Hi, I just installed huffYUV b/c I wanted to output my premiere project using a loseless video codec. My problem is when I export it via premiere I get the entire video looking like this with the audio running fine in the background.


I tried using this codec in virtualdub to see if it was just premiere, but everytime I would open the video created by virtualdub in windows media player it crashes. I also tried enabling console window logging but no window would popup during compression. Any ideas what my problem could be...Perhaps a conflict with another codec or something or a previous version of huffYUV.

I've the same problem. New version of huffuyv crash any program which tries to access the files created with it.

I have no problems with it. Capped at 720x576 and played back again without problems on a P4.

This is with the field treshhold at 288, and no option enabled except "Enable full size output buffer". Both compression methods ar set to best.

After a bit of messing around here is what I discovered:
Bad output files are only created when it encodes to RGB. Converting to YUY2 will output correct video.
Source file is being passed in as RGB32.
Enabling Reduced resolution causes RGB mode to work.

Hopefully this information is helpfull in fixing the problem.
