Recommended intermediate HD codec
I have a football match capture in HD (1920x1080i, 30fps) that I want to edit to make it highlights. I need to save it to an intermediate file to apply graphics and transitions and then save it as MKV. I use DGAVCDecDI to decode the file, so I can use Avisynth to process it.
So my question is ¿what codec would you recommend to work as an intermediate one without losing too much quality? My upper limit is 145 Mbps (I thought of DNxHD, but afaik there are no DS codecs). Saludos By ALEX-KID |

there are many lossless codec. Anyway if you want lossy codec with really light loss try MPEG4 ASP (XviD or DivX) with only Iframe and at quant 1 ...

Thanks for your recommendation Sagittaire.
I finally used XviD as you told me, but it was kinda slow, even using avisource. I got about 6-12 fps in my C2Q Q6600. It would have been good to use a codec like DV for SD video, which is fast and it has very little loss. I tested Lagarith with HD video, and it's fast (20 fps), but less efficient (245 mbps!). Maybe there is a good HD codec, fast, good quality I-frame based, bitrate efficient (120-150 mbps@1080i) and DirectShow/VFW compatible somewhere in Internet. Saludos By ALEX-KID |

One of the best loosless codec is IMHO Lagarith: http://lags.leetcode.net/codec.html

based on what you've said of your workflow, you would do well to install AVFS (avisynth virtual file system) and pop the resulting uncompressed (and taking zero real space) file in your editing software to do cuts, fades, etc.
then export from there into anything you want. this would be the fastest i think, bearing in mind i think it's your hard disk that's slowing things up, not your CPU.

Thank you all for your suggestions.
I know there are several lossless codecs, and using them would be optimal, but space (specially on HD video) is an issue on my system. CineForm doesn't have DS support AFAIK. My sources are loaded with DGAVCDecDi plugin, which has some problems when seeking on H.264 broadcast captures. I think AVFS could be my option if the script mounted works as a true uncompressed file when trimming it. I'll post results as soon as I have some time to test. If not, I think I'll have to buy a larger HDD. Saludos By ALEX-KID |

Matrox is the worse crap out there...slow.
From free ones UTVideo is amazing- unmatched speed. You can edit 4K on good PC It's lossless so bitrates are more than 200Mbit for HD. If you can pay than Cineform or Canopus codecs (HQX- many bitrate settings), which you can get by buying Edius or cheap Edius Neo. Andrew Last edited by kolak; 31st May 2011 at 23:45. |

@Alex-Kid
I use x264 as intermediate codec for AVCHD files (camcorder) Code:
x264.exe "script.avs" --tff --bitrate 50000 --vbv-bufsize 5000 --vbv-maxrate 50000 --preset superfast --tune fastdecode --keyint 1 --output "video.264" (--bitrate 75000 --vbv-bufsize 7500 --vbv-maxrate 75000)
