Quote: I've noticed that when I took a snapshot in PD (and used it in the timeline), that the crispness of the picture wasn't as crisp as I expected. I think I've learned that PD takes the snapshot at the resolution that the video was 'shot' at.

So if I was recording at 1920x1080p - (1920 times 1080) ... is 2073600 - the number of pixels used to create the image correct? So it would be almost a 2.1 Mpixel picture? Would this be a 2.1 MB picture? If these two terms relate, then I understand why I'm not quite getting what I expected as I've been taking 8MB and 12 MB pictures for a while and have grown accustomed to the resolution of these.

No, MP does not equate to MB.

The amount of storage space that the pixels take up on the computer varies depending on the file format and compression settings. For example, a 10MP camera image depending on format these pixels can take up anywhere from about 1MB (highly compressed JPEG file) to more than 57 MB (16-bit uncompressed TIFF).

PD uses the same framesize. Some discussion here may be of interest http://forum.cyberlink.com/forum/posts/list/42972.page#221878

CS2014 - I think that you are refering to the 8MP and 12MegaPixel of still photos from a camera. The 2MP refers to the 1920x1080 still photo size and 2K video by many sources.

Don't worry CS. For years I misused an abbreviation when quoting video bitrates, till I was gently corrected. I used to consistently write things like 24MBps instead of 24Mbps.

... and yes - 1920x1080 is 2.1MP so there's nothing wrong with your calculations

Here's a *Megapixel Calculator* I use quite a bit. That website also has some comparisons related to Jeff's comment about file size/resolution & compression.

Will check all the links referenced. I should have realized this though before I posted as I knew (but didn't realize when I asked in the post) that my stills (pictures), taken on a fujifilm XP70 - the ones that are taken at 12M (a setting in the camera - looks like it's the mega-pixels that the resulting picture is taken at) - have a resolution of 4608x2592.

I see that my 'stills' have a 4608x2592 resolution but the file size is about 6.5MB. And the compression - JPeg. (did I use the word compression correctly here?)

Those taken on the fujifilm look much sharper than the snapshots I've created in PD - and this all makes sense as those in PD are 1920x1080 (when I create a 'snapshot' from the video I have shot in the past).

Sorry to have wasted your time guys, there's much more serious issues to resolve within this forum - but...

I do appreciate the information as ... I'm learning!

CS

p.s. - interesting how the snapshot in T2 takes on the resolution properties of what is in T1!

Thanks for the pixel calculator Tony but... isn't it just a straight multiplication - horizontal(pixels) times height(pixels) to calculate the mega-pixels per still?

Ah CS!

That introduces a different complication with snapshot resolution.

The shots from your XP70 are 4608x3456, which is 4:3 aspect ratio. If you take a snapshot in a 16:9 project - yes - it'll be 1920x1080. If you take a snapshot of it in a 4:3 project, the snapshot will be full resolution - 4608x3456.

** or does your camera have the option to shoot stills in 16:9? **

In a 16:9 project, the way to maximise snapshot resolution is to crop the image to 16:9. Then your snapshot will be 4608x2592, so it's a 100% crop (no resizing).

Hi Tony,

The XP70 does indeed have many different choices to select from regarding size of picture 'frame'. The 4608x2592 is what I read off of the 'properties' of a picture I took directly from the camera - it was a jpeg.

I forget what I had it set to take that picture but I believe it was a 16:9 format and it was 12 M I think. So that picture is looking pretty high res to me when I compare it to a 'snap shot' that I did IN PD. The snap shot was taken from a 1920x1080 video (recorded at 1920x1080 in the GoPro). So, I can see that difference pretty obviously.

Eventually, and I mean probably a few years down the road, I'll be at the point where I'll justify buying a video camera that will shoot still camera video quality. Do you know what I mean? - where the resolution of a video I'm recording will match the stills that I take now - when I take a snapshot in PD. I know the GoPro does this but I'm trying to keep it at 60 fps. I like my 'slo-mo' when a fish jumps! And before anyone jumps on that, I KNOW the GoPro will shoot 120fps, but the resolution is sacrificed when you do so ( I believe).

Till then, I'll try to take stills with the XP70 or equivalent and video with the GoPro Hero Silver.

The Fuji XP70 can do 4:3, 16:9, 1:1 photos according to this website: http://www.fujifilm.com/products/digital_cameras/xp/finepix_xp70/specifications/ . Looks like a good camera to use around water.

Thanks for that tomasc - guess I didn't look hard enough!

CS - I wasn't able to easily find a 4608x2592 sample shot from an XP70, but I did find one shot on one of its competitors (Olympus TG-4)...

... dropped the shot in the timeline - took a snapshot - full resolution! 4608x2592

Do you have your file preferences set to "Use original video size as snapshot image quality..."? (screenshot attached) If so, your snapshot should be 4608x2592.

Yes... Tony, I can do that too!

What I'm talking about is taking a 'snap-shot' off of a video when I'm in PD13 woring with a video clip I've taken at 1920x1080. Those show up in my project at 1920x1080 and they do not look as high a resolution as the pictures from the XP70. And, like I said, it's all making sense now.

Thanks tom, Jeff, Tony.

DOH!

CS - I've just realised I totally misread your issue. You were taking the snapshot from a 1920x1080 video! I thought you were grabbing a snapshot from a photo from your XP70.

Yes - typically an 11.9MP photo will have superior IQ to a 2.1MP shot!
