Fastest Lossless Video Codec

[lubczyk]

I have a lot of soft-subbed h.264 in mkv files that I want to hardsub so that i can view on my PS3. I obviously add borders and use textsub to compensate for overscan and make permanent subtitles.

The problem arises when I'm ready to transcode:

- Transcoding to x264 in lossless mode is way too slow - about 1 hour, 40 minutes for 24 minutes of video.

- WMV9 Advanced 100% VBR Mode is faster but still takes 50 minutes for 24 minutes of video.

So that leaves me with Divx 6 and Xvid. Do either of these codecs have a lossless mode? IF they do, how fast are they compared to WMV9 and x264?

no...
but you can use x264 lossless with lighter settings and gain a lot of speed.

Will PS3 even play lossless? Did you try a sample?

WMV9 100% quality isn't lossless.

no...
but you can use x264 lossless with lighter settings and gain a lot of speed.

Yep. Do it. Provided you're okay with the large file sizes associated with lossless. Is it really necessary? I would just re-encode at like CRF18 with all fast options.

Too bad the 360 can't display text subs!

ffdshow VfW's HuffYUV can be very fast.

I normally avoid MSU tests, but: http://www.compression.ru/video/codec_comparison/lossless_codecs_2007_en.html

Hi. Prolly a silly question explaining the foundation of my x264 newbishness. ;) but is there only "one" lossless mode for x264 or do the various parameters give a different speed/compression ratio but still beeing lossless ?
If so; anyone care to post a couple of "ok" lossless parameter suggestions like a "fast" one and a "archive" one ?

Best regards
