StreamParser v 2.6 is available. Lots of new features - look at "Help>User Guide" to read about them. You can get it here: http://www.personal-view.com/talks/uploads/FileUpload/8c/7f871a35067e038c5bf3df620af82a.zip Enjoy! Chris

This update to StreamParser fixes a bug where video bitrates were reported as negative numbers with big fast streams. Remember to uninstall old versions first. Enjoy... Chris

This is an update to StreamParser to more accurately handle GH2 files. The camera autoselect will detect GH2 files as either GHx files or GH2 files. Some of the file formats for the GH1 and GH2 are the same, so GH2 is only detected when a file format that is uniquely a GH2 format is detected...

I have posted the release version of StreamParser 2.0. The main addition is support for other cameras. When an unknown camera is detected the video frames will show as gray bars. In the configuration>camera menu item it shows which camera type was detected. I have put every model I've had access...

Attached is StreamParser 2.02. It has support for B frames now, as well as support for other cameras. If you examined GH2 streams with older versions you would not have seen any B frames, even if they were there. The way timings are calculated vas also been changed be based on display times for...

I've been digging into the GH1 firmware code and found that overall bitrate appears to have a big effect on the maximum speed that flash memory writes can occur. I’ve always wondered why the write speed error comes up in AVCHD mode when clearly the data rates are well below what the card can...

According to Panasonic the OIS modes are: Image is continually corrected, so you can see the image clearly on the Live View finder or the LCD. Correction occurs only when you press the shutter release button, providing a greater corrective effect. Continually corrects for up/down camera...

I ran some tests to try and determine how fast SD cards operate in the GH1 the way it uses them. I tested a Transcend class 10 card claiming 20MB/s speed. When I test it as a physical device using 512k blocks it comes very close to the claimed speed (20MB/s) when reading - 19.8MB/s. Writes are...

From what I gather the overall bitrate setting accounts for additional non-video data. Is there any additional data that isn't audio? Is there anything to be gained or lost by setting the 50-52-60 settings to 50-56-60, for example? Is the extra bandwidth ever put to use? Does allocating...

I think a short tutorial on how to test electronic devices might be in order. First of all you can’t really test for success. It amounts to trying to prove a negative – that no errors exist. If you wanted to be confident that you will not get errors in 1000 hours of shooting you would have to...

I'm trying to determine the effect of the pulses, or spikes, that appear with EyeStream have on image quality. I think the term "pulse" has been used to describe a couple of different things. What I mean is this kind of pulse (look at the huge P frame right before the I frame): or, an...

I just sent a donation for this project and I noticed that the paypal draft was to a "Rich Hibner". Who are you? Chris

Flash memory devices are more complex than standard computer memory. Computer RAM always operates at full speed and is completely reliable at that speed. Flash systems are actually arrays of inherently unreliable memory with a pool of extra memory allocated for error correction. A microprocessor...

This is great. I ask a simple question and get this great education in the process. This forum rocks! Chris

I was wondering... I know DV cameras have trouble with blockiness with pure red and pure blue. I've also learned (here) that blue/green screen work is very hard to get right with the DVX. I'm guessing that's partially because of the blockiness problem. So, I have some questions: Is...

I was wondering - has anybody made any charts comparing cinelike, cinelike-d and cinelike-v gamma curves? I've seen ones that compare cinelike to the others, but not ones that compare these three to each other.

I've been lurking for awhile now - I have to say that this is absolutely one of the best, most informative forums I've ever seen - about any subject! There is one thing about scene setups I haven't figured out yet, and I was hoping somebody could help me: What does "Vertical Detail Level"...
