Compressing RAWS

Postby Niwa » Tue Jan 09, 2007 5:29 pm

I dont know if this is the right section to ask but I had problem with my raws after i compressed them to lossless and the the results ended up to 31gb for the first eps of Kanon 2006. Isnt there any other options to make the size smaller ?

What codec were you using? HuffYUV and Lagarith both offer smaller filesizes than uncompressed RGB while still being lossless.

Also, this demonstrates the value of only cutting the clips you need, rather than converting whole episodes.

I was using Lagarith, yeah i should probably do that instead of stupid me converting these raw vids to DivX 4.0 since premiere couldnt support version after that. It worked good in the start but it freezed a lot of times later and i had to shut down premiere everytime that happened. I had like 27sec done of that project but i couldnt continue freezing like that.

well for raws, normally a simple 2 sec clip in lagarith could easily be 400 mb.

right click on the file and check the frame rate. normally for raws its like 119 fps.

if that is true then use avisynth to convert your raw to another frame rate such as 23.976/29.97. then when you make a clip it just be smaller

Use avi2tc if it's 120fps. It'll remove the dummy frames and leave you with the file as it should be - 23.976 or 29.97 (I can never remember - I haven't used it in ages). That way there aren't potential frame-accuracy problems - meaning, cutting out real frames and converting dummies to 'real' frames; I don't know if that can cause motion problems or not, and because of avi2tc there's not really a reason to find out.
