An avs command to convert all frames to key frames? (orig: mkv file)

Hello, I was wondering if there was an avs command to convert each frame in a mkv file (h.264 codec) to a key frame? I'm told converting each mkv file to a loseless codec will solve this problem, but unfortunately I only have about 10 free gigs left on my HD ( and a total of about 18.5 gigs if I were to delete the 24 350MB mkv files), so I really don't think making each file a loseless codec is an option for me. So I believe these are my options: #1. use a avs command that will make each frame a key fram using my original mkv files (if such a command exists) #2. I don't really know. Any suggestions? I'd be willing to do anything as long as it doesn't involve buying a new HD :) Thanks. P.S. Does Premiere have a tool to make each frame a key frame? I would check this myself but I won't have access to my own computer for 2 more weeks.

Just out of curiosity, why would you want to do this?

there are no avisynth command for that as avisynth does not encode the video. It only delivers the uncompressed frames to the encoder (that is why avisynth is called a frame-server :) )

In an avisynth script, every frame IS a keyframe.

Sounds like what you really want is a lossy keyframe-only codec, like MJPEG or DV. David

Lossless will be huge. You have a DVD burner? Burn some stuff and make room, they're going to be huge. Then install huffyuv of lagarith, load your avisynth into vdub, re-encode into one of the above (choosing fast recompress), and load your shiny new avi file into premiere. MJPEG, DV, and specifically configured XviD can work if you really can't free up the space, as david mentioned. Avisynth is all keyframes on the front, the part programs see, but it still has to rely on the decoder (from DirectShowSource) sending it frames properly on the back, and not all codecs/decoders are able to do that.
