How to use lossless codec ???

[salman1]

Hi sorry for making new thread here but i want to use lossless codec to create avi file. some of codec i found are Huffyuv, Snow, Lagarith also tell me which of this is better one. also if you know any others that is better please tell me it. now my question is how do i use it they don't provide any software like megui but they only provide .dll file so what program do i need to use in order to use one of these lossless codec? i know they create big file but i still like to try and see. i hope you don't mind me trying it out. hehe.. :) thanks a lot

i am planning to use that lossless file as my source for my xvid encode. so i will load up that file and compress that 2 xvid . do i still need to enter values and matrix and all other option that xvid profile gives in megui if i do 2 cd rip using that lossless file to xvid and is CBR pass ok for it or i have to do 2 passes encoding ? thanks

They include a .inf file, which if you right click/install with the DLL being in the same folder, will install the codec.

HuffYUV is the fastest, but the least effective at compression.

Lagarith offers the YV12 colorspace and is much more effective than HuffYUV at low-complexity frames (such as completely black frames) and somewhat better at ordinary frames. It is quite a bit slower though.

Snow isn't a lossless codec per se--its a lossy codec with a lossless option, just like H.264. Its not good enough to be worthwhile IMO.

FFV1 comes with FFDshow and is better than both Lagarith and HuffYUV (choose AC compression option and Large context model for best compression) but is slower still.

H.264 lossless is slightly inferior to FFV1 and pretty slow to compress, but much faster to decompress. It is the only one of the lossless compressors listed here that is faster to decompress than to compress. FFV1 I believe is similar in speed, and HuffYUV/Lagarith are much faster to compress than to decompress.

Thanks but how do i use it after i install ?? using what software can some one pls tell me?

You need an encoding application, such as VirtualDub.

oh ok but then i got back to create my 2 cd rip using xvid do i have to select my xvid profiles like matrix and other setting ? or just drop the size of file ? if yes how do i just drop the files ? Thanks a lot

You open the avisynth script, and save it to lossless when you'd normally save it to xvid. Then you open up the lossless and finish saving to xvid. The lossless is just an extra save+load step, it doesn't change anything you have to do to encode with it, as long as you're doing it manually.

If you use a gui, it's better to get one that supports lossless directly (like megui's pre-rendering job), it's usually not worth the trouble and crowbarring the extra steps into its workflow.

yes but let me explain you again. :) because i think you didn't get my point

In virtual dub i will open my script that has filters in it then i will save it to lossless codes then i will open that lossless file to create my 2 cd xvid rip so do i have to select matrix and other xvid profile setting. or will CBR passes will be ok for it? lossless file will become my source so how to use in xvid avi file with or without xvid profiles. is one passes encoding will be okay ?? i hope you will understand better if not i will write third time if not then fourth time then so on and so on .. Thanks :) sorry for my bad english

Use Google to find some guides on XviD encoding. There's so much good information out there that it is senseless to repeat it all here.

You're also now off-topic for your own post. :)
