Lagarith is a lossless video codec intended for editing and archiving. However, for high static scenes or highly compressible scenes, Lagarith significantly outperforms Huffyuv. Lagarith is able to outperform Huffyuv due to the fact that it uses a much better compression method. Pixel values are first predicted using median prediction the same method used when "Predict Median" is selected in Huffyuv. This results in a much more compressible data stream.

In Huffyuv, this byte stream would then be compress using Huffman compression. In Lagarith, the byte stream co to jest lagarith loss less codec be subjected to a modified Run Length Encoding if it will result in better compression.

The resulting byte stream from that is then compressed using Arithmetic compression, which, unlike Huffman compression, can average fractional bits per symbol. This allows the compressed size to be very close to the entropy of the data, and is why Lagarith can compress simple frames much better than Huffyuv, and avoid expanding high static video. Additionally, Lagarith has support for null frames; if the previous frame is mathematically identical to the current, the foals london thunder mp3 frame is discarded and the decoder will simply use co to jest lagarith loss less codec previous frame again.

Other colorspace conversion routines were taken from AviSynth. Lagarith is released under the GPL. Lagarith was last updated on December 8, Thanks to AbsoluteDestiny and Zarxrax for helping with testing the codec, Andrew Dunstan for providing optimized colorspace conversion routines for the X64 build, Ben Rudiak-Gould for developing Huffyuv and AviSynth, and to Avery Lee for helping speed up the decoder as well as having developed VirtualDub.

I'm announcing big photoshop files for my friend since he's never joined this forum. He has made a very nice lossless codec called Lagarith. It runs at about half the speed of huffyuv, so it can work well for capturing video on most systems. The compression ratio is slightly better than corepng I didnt enable delta frames in corepng in my test.

It is an interframe codec all keyframes so it works very well for editing. It does have a null frames option though, which you can enable to make it encode null frames if there is no difference from one frame to the next.

It's also open source. A reduced resolution mode is currently being implemented, which will be a extremely nice feature for video editors. I personally use this as my standard lossless codec now, replacing huffyuv and vble. From all the lossless codecs that I have tried, it offers the best mix of compression, speed, and stability, in my opinion.

Wow, very nice codec Since the compression method sounds similar to ffv1, lets see how they compare. My benchmarks on a random chapter of a random DVD I co to jest lagarith loss less codec on hand Ghost in the Shell 2; mostly CG, cropped but not filtered YUY2 because that's what all these codecs have in commonx, frames There were no duplicate frames in this clip, so that feature of lagarith wasn't tested.

But note that MEncoder has a similar duplicate frame remover that can be applied to any codec, so ffv1, ffvhuff, and ljpeg would benefit the same amount. This is just one source; YMMV.

Last edited by akupenguin; 6th November at Lagarith doesn't seem to be co to jest lagarith loss less codec by the "null frames" option when encoding YUV.

Is it supposed to be working? Yes, I'm sure the frames are perfectly identical. I also can't get it to encode RGB vdub crashes when I begin encoding. SirLagsalot just fixed RGB. Another chapter of another random DVD "Ghiblies 2", x, frames, cropped but not filtered. Yes, I made sure all of these are really lossless.

After seeing the good results of ffv1, i decided to try a comparison myself, and see if I could actually get the codec working this time.

I've never been able to get either ff huffyuv or ffv1 working the couple times that I tried them in the past. Last edited by Zarxrax; 4th December at Looks like ffvhuff hasn't been included in ffdshow yet.

Co to jest lagarith loss less codec edited by akupenguin; 31st May at I've managed to get intra-only FFV1 to encode and decode at the same rates and faster compared to Laga, with decent compression gain. I hate to be such a dick, but I've never really seen the point of lagarith I'll post my test results tomorrow or Monday when I'm home. Sorry but the results i posted before were borked here are the correct ones 1: Well, if you like it, use it.

I still don't see any practical use, FFV1 pretty much covers all bases. I guess I'm just too supportive of FFV1: P Laga and me go back a ways though. The story of my distaste for it is too long and political to go into without being OT, so I'll step off here. The time now is Lagarith lossless codec. User Name. Remember Me? Mark Forums Read.

Lagarith seems to be a good intermediate range codec: Originally posted by Zarxrax ff huffyuv resulting files are corrupt. Originally posted by akupenguin What version of libavcodec?

Last week it was split lotr conquest keygen two codecs: Originally posted by Zarxrax I actually wasn't sure what the context setting did, so I left it at the defaults, which I assumed would result in the best compression.

I didn't enable P-frames because the other codecs that I tested do not support this feature, thus it would not be a fair comparison. Also, P-frames are worthless for the applications that I typically use lossless files for, so it does not interest me. Find More Posts by RadicalEd. Australia Posts: Find More Posts by dragongodz.
