QuickTime Player 10.1 no more includes the ability to save a movie file in the same format as the original movie after editing it? No, it doesn't!

Question

Since upgraded to Lion, I have to wait for QuickTime Player 10.1 to "CONVERT" every file that I edited in it.
Yes, it might save some disk space for me.(Which is not always the case though.) But it also takes almost 10 times or more as it did when back on Snow Leopard with QuickTime Player 10.0 there I could save any file in the same format as the original movie WITH NO NEED TO CONVERT IT.
Now I have to wait like 10 minutes to delete just a few frames.(The time it takes depends upon the original size of that movie. The larger the longer.) And guess what? If you have two clips originally split up from a movie and sperately getting saved(converted actually) with a loooooooot of time, and you naively added one of them to the other's end and then saved the finished one. It converts AGAIN! Doing so back on Snow Leopard with QuickTime Player 10.0 only takes you even a few seconds only!
Seriously, are we eating Apple or dirt this time?

Answer 1

My existing movies are all the following types straight from FinalCut
Apple Intermediate Codec, 1920 × 1080, Millions
16-bit Integer (Little Endian), Stereo, 48.000 kHz
This particular movie is 6.66 Gb
The new Quicktime player in OS Mavericks converts these to the following format:
Apple ProRes 422, 1920 x 1080
Linear PCM, 16 bit little-endian signed integer, 2 channels, 48000 Hz
And a movie size of 6.48 Gb
It seems obvious from other forum posts this is a planned move so that everything is the "new mobile device" ready state/format. To use Marc Speth's post as material....

this is probably about dumbing down desk top OS to that pf iPhones and iPads. This is not what I paid good money to own a Mac Book Pro for....
Today I rolled all the back to Snow Leopard. Really good move...... All those new features hey? I lost the ability to work in spaces and of course the whole Quicktime debacle.
The rolling back process was easy, restored from a point prior to installing Lion and Mavericks and the only issue was my iPhoto libraries. Thank my stars that I still had back ups that I had not converted yet.... viva la Mavericks...NOT. Apple can keep it.
Unsure if you are just venting or if there is supposed to be a question here. Basically, I assumed this to be Apple's idea of an improvement. That is, I really believe the ProRes 422 codec is a better intermediate codec than the AIC codec but most of my old HDV camcorder family tapes were imported by iMovie (for compatibility with my wife's non-FCP computer configuration) and, like your content, is/remains stored as AIC/PCM MOV files. At first I thought this might be a generalized change affecting all QT X based apps but when I went to check the latest iMovie v10.0 update, became confused when I noted that AIC source files were not automatically updated to ProRes 422 and continue to play natively in the iMovie source media viewer.
I guess this is supposed to be a logical evoluption and we were supposed to have seen the "handwriting on the wall" dating back to when Apple's first released the free ProRess "player" ProRes 422 codec. Still, it would have been nice if Apple had given some warning during the last few years so users could plan and prepare for such a drastic change. For the moment, I am just thankful that AIC remains, at least temporarily, supported nativelyby the iMovie video editor under Mavericks. Thank goodness for small favors.
