yeah kind of tough to tell any real progress being made w-out a solid comparison, side by side. Pappas does a real nice job of this- we should use same technique
 
Standardizing the test reports would probably be very helpful!

tester13, what specific parameters would you like reported with each post?

I totally agree.

Table above is a good start but tester13 must have final say as he is the one pulling the strings around here.
 
Lack of upscaling seems to help with slower cards.

Pappas, what card did you use to get the reliable high bit rate rolling?

Sandisk extreme 8gig class 10.

Here are a few tests did over the weekend.

This was a filmed 720 then scaled up. Very cloudy, and getting dark when this was shot with a 200mm.

Man.. I am in trouble now. I used to be happy with footage coming out of shooting in FHD avchd and transcoding/pulldown in cineform neoscene. Yesterday I shot the same scene in AVCHD FHD and MJPEG(higher bit) and whew.. quite big difference.. I love this higher bit MJPEG footage with no good way to transcode to 24fps.. Hopefully tester13 can improve AVCHD like MJPEG or can nail MJPEG 24fps!!!

Here are a few screen grabs with the following MJPEG patch:

Quality settings (E1 to E4) - 352, 220, 200, 184
Table settings (E1 to E4) - 24, 24, 24, 24

Quicktime reports 54Mbit/s. I'm shooting with stock 14-45mm lens. I have been shooting with this patch for a while now. No problems except the fact that you can't view the files in camera (doesn't freeze - just gives you a card error message).

Thanks for the settings! Just tried it and looks phenomenal! No artifacting records nicely on my class 6! LOVE IT!

awesome--

just a note on thread here though....guys if your going to "quote" someone please omit the gigantic jpegs- just highlight them like text and delete from the quote- you still get your point across, but it really bogs down the forum with all these repeated ginormous jpegs.:furious3:

Not trying to be the hall monitor, but I think other will agree, to see the images once, should suffice.:)

so did you record 720 @ 60mbps? was 720p24- any skipped frames/frame duplication

can you share a clip?

thanks

I didnt use 24p I used 30p...max bitrate ive seen on my clips was around 51mbps
I have a very messy back garden that caused me a lot of probs before with artifacts...but not any more...and if theres any there...its very very fine.
I have a vimeo account and will try to upload a uncompressed clip (If i have some space this week...if not then saturday afternoon)
*edit no space* the video file is 360mb

Just shot some stuff in my back yard with the same settings - similar findings as yours. High detailed scenes, scenes with a lot of green, etc., all came in fine @ 720p30 MJPEG. Couldn't get the codec to generate any mud at all (even stopping down to f/11 and cranking the shutter then panning like crazy over high detailed grass, plants, etc). Used a regular 16gb Class 6 SD card from Transcend.

I shot in "Smooth" mode with Contrast at -2, everything else down the middle.

If there's interest I'll throw up some clips on Vimeo. It's just boring back yard stuff but the implications are very nice! We need to do something about the 3 minute recording limit, though... and hopefully 30fps --> 24.
 
If Pana release f/w for sdxc card compatability

If Pana release f/w for sdxc card compatability

the format is exfat, no file limit! and possible speed increase.

Would definitely be happy to see some 720 or 1080/24 material. Compression breakthroughs are great, framerate breakthroughs are tipping points.
 
Here is a test I did with the settings slyn4ice used.
I got 48.80 mb/s at 720/30p on this clip.
And I also wanted to see how the footage handled being graded in Color.

As much fun as it is to be teased with stills, can someone throw something up on vimeo already? What are people shy? :)
