Vimeo vs Youtube & my first try at multiple lenses & color grading hacked GH1 native

I spat this little puppy out of Sony Vegas 9d after getting some info on how to set everything up for the highest quality native editing of the new hacked GH1 50mbit
'c' settings:

http://www.youtube.com/watch?v=MO_h_Irqn_4&hd=1

(be sure to select 1080p and full screen on a nice big display to see the detail) I played it out of my friends youtube enabled bluray player and couldn't believe it, it looked better than any of the broadcast HD network channels codecs which always are loaded with blockies.

Anyway this was my first attempt at playing with some color correction to give the indoor looks a more antique sepia like tone. Everything was all natural light from iso 100 all the way up to iso 1600 on the old man's face at the end with pretty much just the light of the TV illuminating him.

Used the kit lens mostly for outdoor and the 20mm pancake lens indoor.

Edited in sony vegas then spit out to a 20mbit mpeg 4.

I just upgraded to premiere cs5 and was trying to do it in that but I was having issues with it crashing, and I'm not quite as good on it yet, vegas seems so much easier to edit on.

I was pretty fairly impressed with the quality of th youtube encode, it's the best I have gotten so far, and while it falls apart a little in the dark scenes it holds up fairly well in other areas considering it's now the 3rd re compression.

I couldn't upload it to vimeo because it was over 500 megs but you really need to see the original mpeg 4. No blockies or mud anywhere even on a really huge screen even in the very dim high iso interior shots.

So two questions.. #1 has youtube's encoding surpasssed vimeo as far as actual online streaming? Vimeo always dumbs down your resolution to 1280 x 720p which really kills the detail to me and makes everything look too soft, especially on large displays that everyone has now with netflix and youtube coming in right off their bluray box into their huge living room hdtv.

Secondly... this is the very FIRST time I started to encounter some 'little chunkies' or stuttering on some of the footage while ediiting in vegas on the native 24p avchd files.

The biggest trouble being the most high bit rate shot of the leaves of the tree in the wind.

Why exactly is this? I have heard of how 'avchd' can be a tough format to edit on if you don't have a state of the art machine (which I do) but what causes it?

For instance, if I open up the original .mts clips in Win 7 media player, which plays native avchd files beautifully, I don't even see my processor go up past 2% usage (quad core 3.2 i7) I can literally open up many of them and have them all playing real time out to multiple flatscreen monitors (I have a 4 monitor ati hd 4850 x2 video card) and the processor doesn't seem to even flinch...

Why does it flinch sometimes in an editing program? For the most part it didn't, but on a few scenes, it did.

Thanks,

Thanks,

That was all the hack 'c' settings with 24p n checked. I know people have complained of 24p native avchd causing crashes but I have had about 95% reliability on my transcend 16gb class 6 card. I have only had it crash once. I absolutely love it. Not having 24p n was one of my biggest gripes about the gh1 after the lousy 17mbit codec.

I could never use the 60i wrapped footage natively in vegas before... I would have to go through cineform first and to my eyes, as good as cineform is... you lose a little something and get some added noise in the pulldown removal so I would only do it if I really have to do some extensive color work. I was able to do color grading in vegas in 32 bit space and it worked fairly well, I did a lot of changing on those interior room shots and that is when realtime playback in hd mode did clunk a little bit but I'm saying the lack of an intermediate codec made it easier for the compression to 20bit mpeg4 directly from 50mbit avchd and youtube was able to keep it really clean. I haven't seen cleaner youtube footage than that or vimeo footage.
 
Looks great.

I haven't heard that track since 1978 when I was 19 and played in a Chicago cover band. :Drogar-Shock(DBG):
 
Daaaammmn... that looks sweet. I'm too chickenshite to hack just now with a few projects coming up, but I'd love to try this on CS5. I guess I need to grow a pair and going ahead and hack.
 
After the hack you essentially own a totally new camera with about 3 times the quality level it had before.

Vegas only uses the processor and not the video card so when a high bitrate AVCHD (probably 40mb +) from the GH1 is previewed it stutters. (even on your spec machine)

Holds out PayPal Hat ............................ hahha (joke from the other thread)
 
Ahhhhhh.... interesting... so when I am just 'playing' a bunch of clips in win 7 it is using the video card and not the processor? and this is why I can have many 1080p avchd clips playing without any hit to the processor at all? I have a ATI 4850 x2 with 2 gig video ram... huge monster of a card that is basically two 4850s on one card. I was upset when I found out CS5 isn't going to take advantage of it... but it seems they are teaming up with invidia and discluding all other gfx cards I personally have always found ati cards to be faster and lower price and less heat.
 
Yep, that's why. Have you tried enabling more cores in Vegas preferences, the default is 4, you have many more. Try setting it to 8.
 
That big video card will come in handy if you use Magic bullets Looks within Vegas for grading though, it uses the video card.

Bloody hell that kit lens is sharp!!

i felt bad for your dad! made me laugh though, reminded me of my grandfather.
20mbps mp4 sure looks good!
makes me think i should render my mp4s at a higher bitrate....been using 10mbps.
 
Lol that's not my dad.. that's a guy a rent my studio apartment from... he's 92!!! I kinda take care of the old guy and get him groceries and stuff. He's like the old crotchety guy from Disney's 'up'. I have some pretty funny moments of him on film.

I have looked all through every menu and I can't find this setting to set the cores... I would assume a 64 bit version of the program would automatically use all the cores you have available and that is what it appears to be doing from watching the process monitor and task manager... 4 hardware cores, 8 virtual cores, all being used from what i can see when I spat out a blu-ray or DVD was the only time I saw them all pumping at 99% i7 is fast and sweet and the best PC purchase I have made in all the things I have owned computer wise. This thing glides.
 
No lie-that IS the cleanest 1080P I've ever seen on YouTube! Great job-some of the shots felt just like looking out a window, esp. the closeup of the dog! excellent! I think you should project it on a huge screen and report your impressions! Congrats!

I'm assuming you have Vegas Pro 9 or similar, go to options, preferences, video tag and you will see ''max number of rendering threads" default is 4.

64 bit version may already be set to 8, i have only 32bit.

I want your kit lens
 
Thanks Brian... yeah I thought that too I was pretty impressed myself when I watched the youtube playback. I'm a pixel peeper and I was pretty damn impressed how it held up for how low birate the youtube 1080p stream is... but I'll be darned it really held together very well! I have played it on a projection system and it looked fantastic. I'm in love with the camera and will be shooting an actual short to enter into festivals next... I think I am done with all my 'testing' phase.

Also thanks Ram for the help I DID find that tab and strangely enough it is set to 16 threads by default... should I leave that or change it back to 8, which is what i actually have?

And why do you not have the kit lens? It didn't seem worth it to me to buy the body without the kit lens... it's a great lens for outdoors! Yeah it's a bit slow but man, the auto focus comes in handy and it's razor spot on. I usually set it in auto when in a rush then switch to manual to lock it down or manual focus pull. I also think things look better at a 50 shutter speed - I even like the flickering of the tv it gave.. that would have disappeared if I just shot at 60 shutter but I liked it and to me there is a difference in motion blur.. but again, I'm a nutty pixel peeper.
