Hey there - again.
I recently got the SVN-PPA for Ubuntu of KDEnlive and the current version of
KDEnlive. I might repeat myself - but it's still not really usable for me. The
recording option ... I think it works with Terratec Grabby (Video4Linux2) - why
don't you let the user freely decide the codecs and formats in which he wants
to record.??
And the second point: AVCHD. (H264). I always record in H264 for it resulting
in smallest filesizes with high CPU Load while decoding. :D I see it's a pretty
hard video codec, but as far as I unterstand it there is one image fully
defined and then only the changes based on the one full picture. If there is a
change, that is too big or o heavy there will be another full frame. (i-Frame
(????)) I see that even Adobe Premiere has its problems with this codec, but it
is in my humble opinion the best one for sake of my harddiskdrives. Adobe
(apparently) searched bad to the last i-frame and builds all later changes on
top of it ... so it is pretty slow loading a random position in a video. But
KDEnlive is too slow to accomplish a nice editing envirornment. The video in
Timeline is too slow --- for 5 seconds then there is ja jump to the real
position after the 5 seconds. I can understand it hanging for a while, when I
clicked on a later point in time ...
searching for last iframe ... but if it is always so slow... that's just
unusable ... I hope this critics are not taken personally - And maybe I helped
you to make an even better editing experience for video cutters all around the
world. ;) (nice sentence, ain't it)
