Fast inter-frame lossless codecs?
Think this is the right section.
What are my options for a fast inter-frame codec? I'm recording short snippets losslessly of an online game (Transformice) which has some areas with high motion and a whole lot with none. Inter-frame coding should give a huge benefit for it, but I don't know any codecs that do this. Screenshot example here. Anybody know of any? |

I'm using a VfW build of x264, actually, but unfortunately it's in YV12 which causes noticeable degradation, especially since I'm upscaling later. (If I don't, YouTube does some bizarre resizing that makes the quality awful.)

Capture using HuffYUV or whatever to keep the RGB. Keep in mind, It's all going to be converted to YV12 eventually if you're going to YouTube!
That sample YouTube clip you linked to doesn't look too bad to me in 480p mode. You're using a free video host, keep in mind Since your sample image is 800x600, I can only assume your game can only render in 4x3, correct? If so, you can still get an "HD" stream out of YouTube. Here's how. 1) Capture at 1024x768, or ideally 960x720 if you can 2) Use an AviSynth script like this: Code:
AVISource("cap.avi") #assuming your capture is RGB, right? Spline36Resize(960,720) #Make it 4x3 720p if it isn't already ConvertToYV12(matrix="rec709") # YV12 using TV range rec709 colors, standard for HD AddBorders(160,0,160,0) # Matte it, tricking YouTube into thinking the clip is vanilla 720p Of course, if you're just trying to save space on your capture files I'm not being terribly helpful!!!!

Prefer Camstudio over MSU Screen Capture codec, Camstudio is one of the fastest (in LZO compression mode) screen capture codecs.
MSU offers the best compression rate... at the cost of speed, it is more interesting for archiving. |
