Lossless CODECs

[off1]

Wich lossless CODEC do you sugest for video editing, I want one to be fast and small sized, but still lossless.

I´ve been using Indeo5... Is there something better?

[off1]

Sorry

Sorry, I souldn´t had asked that question without first searching by my own.

And for those who may have the same question, here´s the answer:

"Huffyuv" seems to be an excelent and fast codec, even for capturing.


Well, thanx anyway... (I still accept any better ideas)

I had a similar question a bit back regarding Huffyuv, and "admin" referred me to the LCL (lossless-codec library) codec. Haven't tried it yet, but he described it as slower but with better compression.

[off1]

Thanx a lot Ben, I just downloaded both codecs and I´ll try them during the weekend.

I´ll be posting my results next monday.

lossless codec

do you know if you can use the Huffyuv codec to capture with virtual dub on a nvidia tv tuner card?
i want to put my vhs into divx and wm8
does this give that capability? if so how fast does the processer need to be and how much ram do you need.

I don't know about nvidia, but mine's a generic bt8x8 job.
With my duron750 and 384megs ram I can quite happily capture 384x288 @25fps in huffyuv at 70-80% cpu load. I seem to get quite few dropped frames, in the region of 0.5%, though I leave the audio as PCM and MP3 it later. Really must sort out WM8 sometime.

techno's been tutoring me in the art of capture- read all about it here:

Capturing from VHS

I also have a BT848 capture card and I´ve been using PowerVCR from CyberLink to capture from VHS.

It has a real time MPEG-I and MPEG-II compression, wich gives you the capability of compressing directly to VCD and SVCD formats so you can watch your VHS captured movies directly into your DVD player.

[Apnoea]

What's powerVCR like? I'm running a fairly low power system so the minimal overhead VDub is ideal for me.
Direct into [S]VCD... Unfortunately I never use it 'cos I don't have a separate DVD player!

Your capture card and VDub are totally separate entities. That you set them up to communicate does not in any way lessen this separation. One is operating in one place and the other is operating in another. Just data is shared; nothing else.

To put that in plain language, huffyuv or any other codec should work just fine since your capture card knows nothing about that.

Since you are doing capture however, huffyuv and LCL (another lossless codec) are both good candidates since they both offer the greatest flexibility [read: quality of input] to your post-capture editing. Capture with lossless, edit with lossless, and only when you are ready for your final compression do you move to DivX or whatever. That should always be your method if final quality is your goal.
