	HuffYUV
		Oh by the way I am talking about Huffyuv version 2.1.1.The newer version is no good as far as I'm concerned,when I tried to open the outputted AVI,Windows Explorer would crash.I tried 'Always suggest RGB as the output format'option but it made no difference.
		I was converting some divx.avi's to huffyuv for editing and for later conversion to MPEG2.
		I would recommend to stick with the original huffyuv 2.1.1 version as it work excellent for me. and if a new version comes out i would recommend to test it thoroughly to make sure it works 110%.

	HuffYUV - MultimediaWiki
		HuffYUV is a lossless video compressor for AVI files written by Ben Rudiak-Gould.
		HuffYUV's algorithm is roughly the same as lossless JPEG: it predicts each sample and Huffman-encodes the error.
		The HuffYUV codec compresses an image by predicting the value of a pixel from its neighbors, and computes an error value (delta) by subtracting it from the effective pixel value.

	Обсерватория: Сходка :: Просмотр темы - VD не видит кодек HUFFYUV???
		HUFFYUV, как видно из названия, может обрабатывать только определенный формат потока, в частности YUV (у меня - UYVY).
		Соответственно, Ваш драйвер выдает что-то другое, например, RGB, который,естественно, не буде обрабатываться HUFFYUV.
		Если выбираю YUV12 - пишет, что не может найти драйвера для не-RGB формата, если BTYUV - появляєтсь только кодак Brooktree, а не HUFFYUV.

	Huffyuv \| Software - (DivX/XviD) Digital Digest
		Huffyuv is a very fast, lossless Win32 video codec.
		Huffyuv is intended to replace uncompressed YUV as a video capture format.
		Huffyuv also supports lossless compression of RGB data, so it can be used for the output of programs like VirtualDub.

		OK I tell a lie, there are a number of options available to you but HuffYUV is without a doubt the most stable of these options and Lagarith is the second most stable.
		The main problem with HuffYUV as it is at the moment is that it does not have the ability to store YV12 data.
		To always have HuffYUV always presume the frames are progressive, change this to a number higher than 576.

		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.
		Since YUY2 uses 16 bits per pixel, Huffyuv-compressed YUY2 used to use a value of 16 in the biBitCount field.
		As of version 2.1.1 Huffyuv puts 24 in this field to make them happy, and stores the actual value elsewhere.

	Huffyuv 2.1.1 - CCESP Patch 0.2.2
		Huffyuv and CCE will always use YUY2 for encoding but fall back to RGB for CCE dialogs that display video if the "always rgb output format" checkbox is on!
		Original Huffyuv has a fatal flaw that might lead to crashes due to buffer overflows.
		However, it looks like he uses the Huffyuv reported buffer size to keep track of the amount he is writing to the file, but he actually only writes the true content of the buffer which is less than the reported size.

	HuffYUV corrupts my videos! - VideoHelp.com
		If you need to decompress for filtering, then huffyuv can be used to store the decompressed result.
		If I use huffyuv to save the filtered file, It only takes one pass to filter the footage, and then I can use multipass MPEG2 encoder which will only take a few hours.
		A fresh install probably wouldn't fix the huffyuv problem since it was one of the first things I installed.

		Ovviamente, se acquisisci in huffyuv non puoi acquisire in altri formati e viceversa.

		Incidentally, this is using hypercam 2.1, with the huffyuv lossless codec, and XP formatted as NTFS.
		Also, there may be a problem with huffyuv codec for such files, and you try another codec and let me know if you still have this problem?
		I think it would be good to try anyway to record a sample file that is over 2 GB with another codec, maybe the old Windows Video 1 codec, and see what happens.

	settings to capture dvix movies - CDROM-Guide forums
		Best thing to do would be to capture using huffyuv and then frameserve with AVISynth using denoising, deinterlacing, etc. filters as needed.
		There should be a YV12 capable version of huffyuv soon, although I guess that woudn't help if you are converting to mpeg as I don't know of any mpeg encoders that accept YV12 inputs, despite the fact that is what they output.
		I agree that huffyuv is not really for playback, however it is perfect for capturing.

	Videomakers.net - [Codec] Il Codec Huffyuv (Site not responding. Last check: )
		Sul sito ufficiale troverete una spiegazione dettagliata di come ciò sia possibile, ma senza scendere nei particolari si puo' dire che con l'utilizzo di tale forma di compressione i "valori" più ricorrenti vengono rappresentati mediante una codifica di lunghezza più breve rispetto a quelli che invece appaiono più raramente.
		Un video compresso con il codec Huffyuv, richiede circa un terzo dello spazio necessario rispetto a quello di un video non compresso (video a 704x576 richiedono intorno ai 9MB/sec, valore alla portata della maggior parte degli Hard Disk in commercio).
		E' possibile utilizzare il codec Huffyuv anche con formati RGB ma in questo caso si perde la "natura loss-less" di tale compressione...

	SDA Forum - lossless codec comparison
		The latest huffyuv is pretty old, so I was wondering if there were any advances since then.

		If you need speed to avoid framedropping (me!), huffyuv is still the best, but ffdshow's version is the latest and greatest, compressing significantly better.

	Camcorderinfo.com Message Board - What will I need- computer specs for editing
		I don't know specifics about the HUFFYUV codec, but to me, if the end file is smaller, then you're loosing data somewhere, and a loss of data would be loss of qality, but I could be wrong.
		Huffyuv is not based on DCT like all other codecs.
		zxc, I believe that you are confusing lossless encoding by Huffyuv with the ability for it to work with DV in an uncompressed, or 'lossless' state.

	Lagarith Lossless Video Codec
		Lagarith is able to outperform Huffyuv due to the fact that it uses a much better compression method.
		Additionally, the decode speed tends to be slower than the encode speed; this is due to the nature of Arithmetic compression and the prediction algorithm.
		This codec was build using the Huffyuv source as a template, and uses some Huffyuv code, most notably the routine to upsample YUY2 video to RGB and to perform pixel prediction on YUY2 video.

		There are only 2 things you could ever want to choose here - HuffYUV (included in the AMVapp) or Uncompressed RGB (unless you are using the native options of a hardware card).
		The only time I'd honestly advocate using this method is if you have a FAT32 HD or HuffYUV is producing 'dirty frames' as using the frameserver and creating the HuffYUV file in Virtualdub can help with this.
		This may also happen if you are trying to write a large huffyuv file to a Fat32 drive as it can only store 2gig files.

	Guide to capturing, cleaning, and compressing video: Page 2
		Huffyuv is a lossless encoder (meaning that the visual quality is not degraded at all.) It has moderately low CPU usage and yields, on average, a 2:1 compression ratio on a clean signal.
		Huffyuv is typically suited for situations where preservation of quality is of high importance and where hard disk space is not an issue.
		Common sources for Huffyuv would be Digital Cable/Satellite, Hi8 camcorders, or any situation where disk space is not at a premium.

		This is what I consider as good enough for archiving and not too big for archiving.

		It produces video, where every frame is a keyframe, thus very fast when you edit this type of video material.
