When I increase the mids in color corrector my videos loose quality ?
I am currently taking a LOT of night video with the JVC hd7 and I do not have a light. This is why I am opting by just increasing the mids in each video to a higher volume. I find that this is lowering the quality of my videos why is this ?
Michel's point is, is that your video is already "damaged" Video shot at low light does not have all the signal information that video requires. Light is an incredibly important factor in determing signal strength and shooting in low light weakens it, I don't care what your camera's "lux" setting is
So, you will have to do some work. Strangely enough, when you increase the mids, you may have to add some more black to fill in that graininess. No matter what you do, you are going to affect your chroma quality. Some color correction may be necessary
But, really, get yourself a light. Movies shooting on film, which has a far superior gamma rating than video, use huge soft lights even during the day. Light strengthens your video; anytime you have to go and tweak your basic video settings you are affecting that signal.

Throughput drops dramatically when I increase the number of instances in a cluster
Fellow clusterers ....
I have an EJB driver program that pumps work into a WLS cluster. For
scalability, I increase the number of drivers. The drivers have a big pool
of work to pump into the cluster.
I noticed that with 6 (nothing special about that number) drivers, I can get
500K worked items per hour in a single instance (clustered). That is, the
instance is cluster enabled and is watching for multicast, etc..
When I add the second instance into the cluster, the cluster-wide throughput
with the six drivers drops to 370K items per hour. When I add the third
instance, the cluster-wide throughput drops further to 250K items per hour.
When I kill an instance, the throughput grows back to 370K items per hour.
When I kill another instance (to get back to one instance), the throughput
grows back to 500K/hr.
Can somebody point out what we are doing wrong - do we need to tweek some
WLS parameters, do we have to avoid some features that limit cluster
scalability, etc..
My WLS configuration is .....
- WLS 5.1, SP5
- JDK 1.2.1_04c with JIT, no Hotspot
- we enabled performance pack
My hardware/software configuration consists of:
- an E4500 - 8 processor database server - this is only running at 15%
server busy
- three E4500 - all 8 processors/6GB RAM - application processors
The cluster is implemented with one instance per application server.
Each application server is only 10-15% busy.
My driver and application is ....
- stateless EJB driver and stateless EJB bean
Your thoughts and comments would be greatly appreciated.
BernieThe short answer is to set the following tuneables on the client side:
java -Dweblogic.system.executeThreadCount=10
-Dweblogic.system.percentSocketReaders=50 <your client program>

Will increasing the buffer size make flash streaming video stop stalling?
I have surmised all this on my own so it could be just a fantasy, but:
I am often the victim of slow internet connections. This means that when I try and watch streaming video it constantly pauses. It's my understanding that increasing the buffer size of flash would help prevent this but I can't figure out how to do that.
ThanksYou can pause the video just long enough for the player to load enough content. Most Flash player show a loading bar if you hover the player. For short pieces you can load the entire content before starting the play.

hello,
i don't have tools needed but , i see one thing is that you enqueue
every time you are greater 3 that means about every 2-3 ms so consumer is really sought
is it really what you want ?
may be you want to start on a treshold so you can use a treshold fonction
if i don't make mistake your square is 10 hz and the daq is configured 25000 sample 25000 hz
so you aquire 1s of signal every 100ms , there is something to correct
make tests and tell us

Why is the video loosing quality when i import?
i just downloaded the final cut pro x trial after wanting something more than imovie, and to be honest i much prefer it to the old final cut.
but someting is going wrong somewhere.
i record gameplay from my xbox and edit to and so on in imovie 11.
so i got final cut pro x trial, imprted my game clips into final cut from imovie, but it isnt as smooth for some reason. rather than running 100% smooth, it jumps a little bit, as if it were a scratched cd.
all the settings seem to be as they should be but im getting nowhere.
any help is much appreciated.What year is your iMac ... how much memory ... which graphics? Have you gone into the Preferences under the Final Cut Pro menu and selected the Playback tab and set to Use Original or Optimized Media ... then under that set the Playback Quality to High Quality?

Three-Way Color Corrector Eyedropper Tool Not Working on Second Display in OSX Maverick
Hello,
Since updating to Mavericks at work on Monday, I have been unable to use the Three-Way Color Corrector's eyedropper tool on a dual-screen setup in Premiere Pro CC.
I have all of my panels, apart from my Program monitor panel, on one display. When I select the Three-Way Color Corrector's white balance eyedropper and go to the second display where my Program panel is, it turns back into an arrow and doesn't allow me to select anything. When I move my Program panel to the same display as the others it lets me use it as normal. Unfortunately that is not how I work and I would like the program to function as normal.
I was wondering if anyone else has had this problem and discovered a solution. I will submit a bug report right now.
Thank you.Hi Punker,
Thanks for posting the workaround. This is a known issue that we're investigating. Fow now the workaround is to:
Goto> System Preferences>Mission Control.
Un-tick "Displays Have Separate Spaces"
Logout or Re-boot system.
The issues should be resolved.
Best,

3 Way Color Corrector causing major slowdown
I'm working on a project at the moment and doing some color correction. When I apply the 3 Way color corrector to clips, it causes some MAJOR slowdown on my time line, even after the clips have rendered, When I remove the filter, the problem disappears. The footage I'm working with is 1440 x 1080, mpeg-4 video from a Canon handicam (not sure make/model, I didn't shoot the footage). I tried searching the forums, and didn't come across anyone else who has run into this problem. I'd rather not use other filters to make my adjustments, as the 3 way really does a good job of cleaning up the image.
FCP 7.0.3.
OSX 10.7.3
2x2.4 Ghz Quad-Core Intel
16GB 1066MHz DDR3 Memory
Thanks in advance,
KyleOkay, thanks for the info Shane. However, that creates another set of issues. The camera actually records in MTS, which I converted to mpeg-4 (given that it appears like it would work). The rough cut is done, and I really don't want to go back and do a recut. The problem is that I can't find a good MTS conversion software that will let me convert to ProRes 422 or ProRes LT. Mpeg Streamclip doesn't even recognize the MTS files, which is obvioiusly annoying.
I'm assuming that if I am able to reconvert the files, I will be able to "replace" them in FCP, as all FCP does is link to files... correct? And is there anything you would recommend in terms of conversion. Should I convert the mpeg4 files I have or try and convert the original MTS files.
It's been a few years since I've done any major editing, so I'm a little out of the loop.
Thanks again for your help.

Audio drops when using Three-Way Color Corrector in CS6
Hello all,
I recently encountered a very odd issue while editing a friends wedding video using Adobe Premiere Pro CS6. I had an interview with a guest laid over a music track and had all the audio adjustments made to both audio tracks so that the levels were where I wanted them. I then added the Three-Way Color Corrector to the video track and corrected the footage to my liking. When I played back this section of the wedding video, half way through the person's interview, his audio cut out. The audio from the music track was still playing, so it was not that audio drop that most people are familiar with within Premiere. I even muted the music track and played back the mentioned section of video and at the same exact point in time his audio just cuts out completely. I checked to see if any weird key frames had been added and nothing had been touched (that I could see). Also, the audio waveforms were still visible. I deleted the Three-Way Color Corrector effect off of the clip and suddenly there were no more audio problems. Eventually, needing color correction, I added an adjustment layer and assigned the Three-Way Color Corrector to that and had no issues, but I still don't see what could have been the problem, and it seems like a glitch to me. Has anyone ever had this happen to them? If so, what are your thoughts? Thanks!The help does not tell you where the Tonal Range output now is as it has moved from the Output Menu.

CS4 + CS5 Brush CURSOR outline disappear when increase the brush size
Hi
In Photoshop CS4 and CS5, the outline of the brush cursor starts to disappear when you increase the brush size.
It's OK under 65px in diameter and it's start to disappear over 66px. In 438px the outline is a single dot and over 439px the cursor outline is completely gone!
I read that it's caused by the old drivers for the video card. I'm using GeForce 8800GT and I updated the driver with the latest version form the nVidia web site. The problem is still here!
HELP?I'm seeing a bit of a pattern of multiple people reporting problems with nVidia 8800 cards. I'm thinking nVidia isn't testing new drivers against this particular model very intensively. See my comments on video cards and drivers in this thread:

Midi instrument stops playing when I move the mouse button
Hi. Weirdest thing. All of a sudden, I started noticing some strange behavior with my midi input. 1) I can play a selection for a given software instrument, but, if I move the mouse, the midi input freezes (for lack of a better term). I am using logic 9, and it happens with whatever instrument I open.
Bottom line, its as if touching/using the mouse freezes the midi input for about 3 seconds, as if the midi got interrupted by the mouse movement. This hasnt alwatys happened, and the midi output region, when I record, the midi region has a big 'X' in the display of the region. What is that, and what does it mean?
Thanks.Hi, thanls for your response, and I looked into the event list, but, I dont have a graps of what it is you are suggesting I do. I am a newbie at this, so please bear with me, and break down that answer into a little bit more simplistic terms.
