Hi Eugene -

I'm not sure what it is you're aghast about Maybe I'm missing something.

PD's snapshots will replicate the resolution of the image/video in the preview screen

Examples:
► Original photo form Canon 7D (cropped to 16:9) - 5104x2871... PD's snapshot = 5104x2871
► Original photo form Canon 7D (no cropping) - 5184x3456... PD's snapshot = 1920x1080
► Sample 4K video clip - 4096x2304... PD's snapshot = 4096x2304

I'd post them here for comparison, but they're not very friendly file sizes. I can tell you that - even zoomed to 500% - there's little visual difference between the original & PD's snapshot.

Your original JPG (x900 resol.jpg) has a file size of 156KB. That makes me question the quality of the original. The Canon 7D JPG (above) resized to 1920x1080 is 1.52MB. Also - in that image - what's the strip down the left side? It looks like part of something else.

In Preferences > File do you have the snapshot option checked - "Use original video size as snapshot whenever possible"?

Cheers - Tony

Enclosed are a few seconds of the original Panasonic 1920x1080 60P video.

Also included is the original ISO test chart in PDF format. The latest Adobe reader will print in tile form , my chart is 200% and has 8 parts taped together. It is surprising how some cameras mangle the chart.

And it comes in very handy for setting the sharpness control, usually near or at zero.

Thanks for the reply.
Yes Tony it is checked. So perhaps, it was not possible?

I will take an other look at this, you are correct, the file size is too small. But the BMP is 8MB, looks the same.

Well, did it again, same result, even tried "full HD preview". Wonder if the format is an issue?

Hi,
I downloaded the video file, brought it into PD 11 and inserted in timeline 1. Previewed at full HD resolution and took a screen capture here is the result. Also took a snapshot within Pd (saved as Jpg) with no difference.

Tony, I too did a 4K video test and the snapshot of it looks great! Same as original video resolution.

PD11 appears not to like 1920x1080 60P??

James1,
thanks. I looked at your files and they look as one would expect.
Must be doing something wrong here and will try some more.

As mentioned above the 4K snapshot came out just fine, used the "new project" command to try that w/o changing any settings.

Thanks again

Eugene -

That can't be right! Your signature says 60p is awesome!

The clip you attached... how did you make it? It bothers me that (at about 00;00;05;00) it starts shimmering. Did you record a screen display of the image or a printed version?

It also bothers me that the source file is in a squibby little PDF file, which was probably generated in Word (or similar), meaning the image itself has been compressed/downsampled to reduce the size of the document. I'm attaching a cropped version of the original ISO image. Much cleaner.

I'll do some testing on your theory about PD not liking 60p, but I think it's going to come down to (a) the quality of the original & (b) how it was recorded.

Tony, there is a wiggle towards the end when I turn off the record, that part should not be used, sorry.

I think I may have found the problem,
the snapshot looks bad if shadow file is enabled, apparently it will not take the snapshot from the original video, even though that feature is enabled too.


This does not explain why the 4K video snapshot turned out ok since the above mentioned settings were the same.

Turning off shadow files will produce good snapshots. Turning them on will produce ghastly snapshots.

As to the chart, it is app 35" wide, made up of 8 sections printed at 1200 dpi. When looking with a magnifying glass at the regions of interest, the edges are very well defined and are unlikely to materially affect the max resolution. When looking at that I do expand the monitor so it is not a limiting factor. At any rate the resolution results are the same as those published by CAMCORDERINFO for the Pana HC-X900M.
I did look at your cropped ISO file and I am sorry to say it looks pretty bad when expanding it, the edges are badly defined, not as crisp as my PDF file as viewed or printed with the Adobe PDF reader.

Tony and James1 thank you for your help. Since I always use shadow files, it appears that I will not be able to use snap shots.

Eugene

OK -

I understand now about the chart now. You only put it in PDF format to attach. That's what I was comparing.

You are absolutely right about shadow files & snapshots! Man - what a difference!

There's a little video on its way to YouTube that was intended to blow your 60p theory out of the water, but I'm glad you've blown mine away in resolving the problem.

Here it is Eugene - a video that proves absolutely zilch! http://youtu.be/6TU6BUIH4E0

Tony, I did look at the video, nicely shot and perfect use for snapshots.

I wonder and hope that Dafydd might have a look at this since he may have the ability to pass it on. Not
much hope though, the button verbiage says:Use original video size as snapshot image whenever possible. I do
not like the last two words. But why is it ok with 4K video?

So over the last ten days I lost the use of SVRT (hiccups near transitions) and now snap shots. Hope this spell ends soon.

Looks like you are heading for the Sydney Opera House, I used to sail with my family too, from the West Coast a number of times to Hawai and Alaska and my furthest trip was to Tahiti on a 36 foot ketch. It was an almost religious experience to watch the Southern Cross go higher and higher every night. Those were the days of Super 8mm. $ 3.00 per minute after editing, 1970 dollars too. We have indeed come a long way.

Eugene -

I can't take any credit for the shooting. My cameras don't shoot 60p I downloaded the clip from Vimeo https://vimeo.com/23133280 - hope ML71 doesn't mind.

I noticed a difference in snapshots from a 4K clip with/without shadow files enabled. The difference isn't as stark, but it's still there. Here are a couple of comparisons... http://youtu.be/wQKYBrFAmKI

With shadow files enabled, it doesn't matter whether you're using 1080p or 4K - the shadow files generated are 720x480 MPEG-2. Oddly, the snapshot still matches the resolution of the original video.

Anyway, what you've found is absolutely correct. With shadow files enabled, the image quality of snapshots suffers.

Question, if you have the shadow files enabled and completed, then disabled again, which snapshot quality arises? HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)
Nvidia GTX 960(4GB)/16GB DDR3/
Canon Vixia HV30/HF-M40/HF-M41/HF-G20/Olympus E-PL5.
Tape capture using 6 VCR, TBC-1000, Elite BVP4+, Sony D8 camcorder with TBC.

Answer -

All the samples I used were taken after shadow edit files were completed.

Snapshots taken before they're completed are fine... as if you weren't using shadow files at all.
