Alparysoft Lossless Video Codec

[traveller]

It seems to be an interesting stuff.
What do you think experts here about it?
Is it a new replace of old,good HuffYUV?

This product is created for lossless video compression. The techniques used by this filter allow to compress videos with compression coefficient 1.1 - 1.9 higher than HuffYUV.

The beta version of Alparysoft Lossless video codec operates only within a Microsoft® DirectShow® environment. Today it represented as two separated DS filters - encoder, decoder and demo application which allow to compress, decompress and preview video files.

depends on how fast it is

But one thing I wonder is:

Where are the lossles audio compression???

I tried to download the thing, but all I got was some small conversion tool. Couldn´t locate the codec anywhere on my system. Will try again.

Huh?

FLAC
Monkey's Audio
WavPack
LossLess Audio
OptimFROG
Shorten
LPAC

You want more?

[Technoid]

tell me, which one of those formats is usable for realtime capturing?

Well, I keep hearing things about FLAC...sooner or later someone will finally decide to not abandon the thought about doing directshow filter out of it (actually, you can do it yourself if you really want to ) It's just a matter of time now when it's a part of vorbis - and in FLAC case, why hurry? cpu's don't allow for everything (in regards to speed) yet...

Because of this, I assumed that you're not talking seriously about use in video capturing. And besides, you still have wav, right? - not much of a difference in file size when we're talking about captures that inlude not only audio but also lossless video, but wav in comparision doesn't use cpu practically...

Aaand realtime capturing using lossless audio compression is doable even now - though only when talking about audio...
But hey, it can be done.

No one of the codecs was an ACM or directshow, and IF it was soo eazy that I could do it myself, then the author would have done it already
As for speed:
HuffYUV dont even saturate a 800mhz cpu when doing fulscreen caps, so I assure you there is cpu's fast enough today.

Even if I wasnt talking about using them for realtime capture they are all useless to me anyway if they arent either ACM or Directshow codecs since then they wont be usable in any of my editing apps.

Perhaps the author doesn't see interest in it? Those are not things meant (by authors) to use in appliance "audio in video files". And from what I've seen others who wish at some point to do filters, lost interest sooner or later too. I think mainly because there's no public interest in it - the downloaded divx/xvid movie lovers won't use it (almost one cd extra just for audio?), and I honestly don't see why people who capture would want to use it much - as I've said, compare the size of your lossless video capture with wav now and what size would it have with half sized audio. Negligible difference IMHO...but not in required processing power (and lossless audio just needs lots of it...sure, FLAC isn't the worse case scenario and it could be done (premise of flac after all: not so much compression, not so much system demanding), but check how LossLess Audio would bring the multi ghz machines to its knees ). And would you like to wait more during editing audio for such small difference in size?

Hey, yo didn't say "realtime video capturing"

[Technoid]

Okay, so I should have been more prcise in my first post, (note to myself; always write 1 to ten pages, someone might not get it) but never the less HDD space isnt free and anything that helps is welcome,

Usualy when capturing, you capture at highest quality posibly then you edit and lastly you compress with the lossy format of your choice, the diff might not be big but in those situations when you can end up needing twice or four times the space as the captured video, the difrens saved migth actualy be the last 10-5 minuts you need

Not sure (somebody would have to test it...anybody?) but I think the thing about which I mentioned in this thread can be done.

[xortam]

I like the idea of capturing lossless and converting to a lossy format that is compatible with the target device/usage. CODECs continue to improve and you can always go back to your original lossless captures and reencode as you see fit.

I did a few tests some time ago with this codec and it dropped frames massively, making it useless for capturing. It seems to be too slow for this purpose, but it's very useful for editing/compositing, as it retains a very high quality picture.
