@jvalal The reason @Psyco mentioned that possibility was because the link showed Amazon acting as a third-party for another seller, as opposed to it shipping from Amazon directly. However, I would not worry about it being a fake, as long as your results are consistent with the testing data I provided for the card.

Did you have a chance to look at the record times I got with various settings using that card and another one? I spent a lot of time testing with it so you and @GH2_fan could see if it was the card that was giving you problems or something else. The Delkin 16GB 95MB/s appears to give similar performance to the SanDisk 32GB 95MB/s, and both cards are noticeably slower than the SanDisk 64GB 95MB/s. I will try to supplement my test data with standard Mysteron data.

@jvalal sure I had a look where the link goes - and sure there are enough people around the internet that try to rip you off (and its pretty easy with redirects and fake homepages).

@Psyco it's a link to Amazon. Did you actually click on it to see where it went or did you just start making snide comments based on the link formatting. I suggest your familiarize yourself with link shortening services that exists, it's a pretty common format online.

@jvalal

What kind of link is this: http://amzn.to/J2a9Wq ?

Are you sure you got a real SanDisk card?

@5thwall @GH2_fan While I've spent the better part of tonight trying to get over a migraine, but it seems a little better at the moment, so I am going to try to see if I can help figure this out at all.

@jvalal I still need you to be more specific. Please include lens, ISO, shooting mode (24H, SH, FSH, etc.), PAL or NTSC setting and how long it recorded before you encountered an error in each mode. I've done the same below for Sedna AQ1 in NTSC and PAL modes on 2 different memory cards, including yours.

Test Part 1: Shooting a high detail painting

Shutter 1/50, f/4.0 or f/5.6 where indicated (with Rokkor f/1.4,) ISO 1600, WB Tungsten.

Sedna AQ1 A (PAL) - 64GB SanDisk 95MB/s

• FSH: 4 m 56 secs to 5m 31s (NO SPAN) tested 2 times
• SH: 1 m 20 secs (f/4.0) 2 m 55 secs (f/5.6) (NO SPAN - write speed error) tested 2 times
• HBR: 5 minutes 31 seconds (NO SPAN) tested 2 times
• 24H: 12-45 minutes before I stopped it manually (SPANS) consistently spanned
• 80%: 8-9 seconds (NO SPAN - write error) tested 3 times

Sedna AQ1 A (NTSC) - 64GB SanDisk 95MB/s

• FSH: 6 minutes 06 seconds (f/5.6) (NO SPAN)
• SH: 6 minutes 16 seconds (f/5.6) (NO SPAN)
• HBR: 6 minutes 05 seconds (f/5.6) (NO SPAN)
• 80%: 7 seconds (NO SPAN - write error)

Sedna AQ1 A (PAL) - 16GB Delkin 95MB/s

• FSH: 8-10 seconds (NO SPAN - write speed error) - tested 2 times
• SH: 7-8 seconds (NO SPAN - write speed error) - tested 3 times
• HBR: 5 minutes 31 seconds (NO SPAN)
• 24H: 3 minutes 53 seconds (NO SPAN)
• 80%: 5 seconds (NO SPAN - write speed error)

Sedna AQ1 A (NTSC) - 16GB Delkin 95MB/s

• FSH: 1 m 44 seconds and stopped (NO SPAN - write speed error)
• SH: Try 1 = 11 secs Try 2 = 15 secs Try 3 = 1 m 15 secs Try 4 = 16 secs (NO SPAN - write speed error)
• HBR: 6 minutes 05 seconds (NO SPAN)
• 24H: 3 minutes 53 seconds (NO SPAN)
• 80%: 5 seconds (NO SPAN - write speed error)

Test Part 2: Shooting a high detail painting

Shutter 1/50, f/5.6 (with Rokkor f/1.4,) ISO 3200, WB Tungsten.

Sedna AQ1 A (NTSC) - 16GB Delkin 95MB/s

• FSH: 6 minutes 05 seconds (NO SPAN) repeated 2x
• SH: Try 1 = 14 secs Try 2 = 33 secs Try 3 = 14 Try 4 = 20 secs (NO SPAN - write speed error)
• HBR: 6 minutes 05 seconds (NO SPAN)
• 24H: 3 minutes 53 seconds (NO SPAN)
• 80%: 5 seconds (NO SPAN - write speed error)

Sedna AQ1 A (PAL) - 16GB Delkin 95MB/s

• FSH: 11-14 seconds (NO SPAN - write speed error) - tested 3 times
• SH: 9 seconds (NO SPAN - write speed error) - tested 4 times with identical results
• HBR: 5 minutes 30 seconds (NO SPAN)

So far, the 64GB SanDisk 95MB/s is performing a lot better than the 16GB Delkin 95 MB/s, but both are having more difficulty with PAL settings than NTSC ones. Only 24H is spanning, and only on the SanDisk 64GB 95MB/s.

Here is some additional data.

Sedna Q20 A (PAL) - 64GB SanDisk 95MB/s

• HBR 5 m 35 s
• FSH 5 min 35 secs
• SH 6m 11 secs

Sedna Q20 A (NTSC) - 64GB SanDisk 95MB/s

Summed up: SH, FSH and HBR all stop after 6 to 7 minutes when shooting ISO 1600 at f/4.0.

80% stops after 7 or 8 seconds.

Mysteron Burst (PAL) - 64GB SanDisk 95MB/s

• HBR 3m 57 secs (setting had time limit built-in)
• FSH 3m 57 secs (setting had time limit built-in)
• SH 3m 57 secs (setting had time limit built-in)
• 24H 9 secs (write-speed error)
• 80% 2 secs (write-speed error)

Mysteron Burst - NO TIME LIMIT (PAL) - 16GB Delkin 95MB/s

• HBR 6m 33 secs (4GB limit)
• FSH (LOCKED UP COMPLETELY AT 4M 28S with a corrupt file without reaching 4GB limit)
• SH 12min 29 s (4GB limit)
• 24H: 5 secs (write-speed error)
• 80%: 2 secs (write-speed error)

Mysteron Burst - NO TIME LIMIT (PAL & NTSC gave same results) - 64GB SanDisk 95MB/s

• HBR 6m 33 secs (4GB limit)
• FSH 6 m 32 secs (4GB limit)
• SH 31M + (I stopped the recording at this point - SPANS)
• 24H 7 secs (write-speed error)
• 80% 2 sec (write-speed error)

After several weeks of testing Sedna I ran into a spanning problem with Q20 "C." It seemed of the three to be handling motion and handheld instability the smoothest. I use a Sandisk 16GB Class 10 95MB/s SDHC card. I guess I had never really let Sedna roll during an interview before and assumed if there was a spanning issue it would stop recording. I guess I was wrong. Still, all the files seemed saved (I hope!) and to be in divided files which are 4.29 gb each. FCP and in-camera playback would not even see these files. After trying a few options Clipwrap saved the day and converted the problem files. I guess spanning is just something we have to live with with Sedna? I continue to be floored with the ever increasing quality of the GH2 footage, thank-you Driftwood, Vitaliy, and everyone.

@thepalalias When recording in 1080i50, it stops around a minute and a half. Once again, I adjusted the bitrates to 50M and 100M, and was recording on the former.

@GH2_fan So you are using the new card but it is giving you that error? How long does it tend to record before giving you that error.

@jvalal I am looking through your old posts trying to find the specific issue you mentioned. Please mention what version you are using and which settings you have configured it with.

EDIT: Went through your old posts and could not find the answers I was looking for. In my testing yesterday, no patch encountered those sort of write errors in 24H or SH mode on any of the cards used with any settings in NTSC. We did not test EX modes. The card you linked to only had a write speed error on one test and that was using Mysteron Burst in a very high detail shot.

Did you try re-formatting the card?

Shot on Sedna AQ1, our entry for the Sci-Fi London 48 Hour Film Challenge.

Thank-you @vitaliy_kiselev @driftwood and @shian

hey everybody

here a short video that i shot yesterday for a project. sedna A AQ1 with canon FD50mm F1.4 and 14-140HD

iwanttomaketheworldabetterplace.com

and this is an other one

@Kihlian A lot of people turned out for the test and good times were had by all. If you have ever tried to direct 7 other cameramen, shoot footage yourself and direct on camera talent, you may have a sense for how tired I was at the end of it, but it waas so great to conduct a comparison at a level no one had really attempted before.

Not all the settings I had wanted to compare, could be but we got some nice 1 to 1 pairings, nonetheless. There may be some of us shooting supplemental testing soon to fill in the gaps a bit more. But I think one of my favorite moments was when six of us were standing side by side, shooting the same subject, swapping in different lenses until each had been shot with the patches loaded on our respective cameras in the streetlight at night. At that point, everyone agreed about one thing: they wanted a Nokton. ;)

The footage I can`t wait to see is the Mysteron vs Mysteron Burst 1 to 1 comparison.
