Hi all,

I have some material I shot some time ago encoded as MS-MPEG4 v2, 3000 kbps, 1 keyframe each 30 frames.
I get a crash at Premiere 6.5 when I try to open some of those files (not all of them). A friend told me the temporal compression is likely to be the root cause to those crashes, hence to solve them I should convert those files to I-frame only. He also told me it might possible to do so without having to reencode the keyframes. My feeling is that adding 29 keyframes per second (even when raising the bitrate to the maximum of 6000 kbps) will ultimately degrate the spatial compression (within the keyframes).
Does anybody know if thatīs true? And how should I proceed?
I am willing to do it that way, instead of using another codec, so I donīt any new types of losses.

Thanks for you help,
Pedro
