Hi Jim,
How large are your LOG files as compared to other formats? just wondering about how much space it takes on the mSD chip.  is it like RAW files?  I have not had a chance to try this yet, but I get the free version of the DaVinci program.... wow...

Hey Rich, the LOG files don't take any more space, it's more about protecting all of the tonal variations in the image by making it intentionally low contrast and low saturation.   

So think of it more as a conservative color palette rather than a file format or CODEC.    Whether you shoot LOG or NORMAL the file type and size will be exactly the same.
Now, when you leave DaVinci you will change the file/CODEC type and your resulting file will be much larger, possibly 3 - 6 times larger.   This is because h.264/MP4 is highly compressed and not good for editing/mastering, it is generally only used as a delivery format.   But camera makers like to provide small files and aren't usually worried about getting the best quality, so use it as an acquisition format.

I've been flying but not to much shooting. OK on the fixed Aperture considering that the camera is fixed at Infinity. The weather is starting to break here in New England finally so we should have some color soon I hope? Right now everything is Blah!

The fixed aperture makes it faster to change other settings on the fly and yiu're right about infinity, but it would be nice to be able to change it as we could use it to control light and wouldn't need to increase the shutter speed.

Hi Rodger,

Yes, would be more expensive as it would have to be physical, can't be electronic as that's already covered in ISO and shutter.

But since it's fixed at f/2.8 it already has the shallowest DOF, which is the most challenging for focus.   
So being able to close it down would have ZERO effect on focus as it would only get deeper as you stopped down towards f/16, but imagine how great it would be to cut out 5 stops of light with the aperture alone!

All it would do is control light and that would be a great tool in the battle against both overexposure and jello.

Spot on Jim, but the cost an changes in the program would be immense. We can't seem to get it right with what we have now. I cn\an only hope that the Inspire users don't get thrown aside! If that is where we end up I for one will be out of using DJI for anything! Maybe it is time to move on!

I have a feeling they will come out with a new, higher end camera for the Inspire.   I don't expect them to alter the existing one.   The app could sense the new model and have any further settings necessary.

Very nice footage Jim.  I wish I had your talent.  I've been watching your tutorials, which have been a huge help.  Thanks for taking the time to help the rest of us newcomers.

We've only flown our Inspire 1 twice now.  The aerial footage looks great on the iPad 3 when it's connected to the Inspire 1.  However, once we download the MOV files and play them on Quicktime, they look grainy and the playback stutters.  We are trying to figure out why this is happening.  Any thoughts?

Hi Mary, thanks for your kind words!

The stuttering playback is because highly compressed 4k footage is difficult for computers to play unless they are really powerful.  This is why it's sometimes a good idea to color correct before editing and at the same time transfer the footage to a CODEC (cinoression type) that's easier for the compute to play.

The graininess is often a sign that you may have underexposed the footage.  If it's beyond grainy, more like a bunch of XXXXXX in highly detailed images it's more likely that you're seeing compression artifacts and you are filling something too complex for the camera.  

Make sure to use the exposure tools I show in the first tutorial, they are your best friend for exposing correctly.

All the best,

Jim

Jim,
Do you know if there is such a thing as a "dial in" ND filter? in 37mm
I got CPL and ND9  in Japanese optical glass they are heavy but the footage is fine. I guess by using a heavy filter i maybe straining the gimbal wee bit.

anyway would be nice to have a "dial in" ND filters (if there is such a thing) just like CPL

Thanks i love your videos and your online manner and transparency and willingness to teach

There are but heavy. Singh-Ray Filters. Bob may make one for you in the size you need. Will be a bit pricy though. You could also use a Gel but it would have to be very tight and maintain a flat surface or you will have a bit  of distortion. Jim my have some tricks up his sleeve also.

What fun would it be if we did venture out there. Some times that is when you catch a once in a lifetime shot that you didn't even plan. Then again you can think it all out and it just doesn't happen. At least Digital doesn't cost a fortune like Film did.

Great video man! I don't have my Inspire 1 yet, but I have already learned so much from this site! Can't wait to pick mine up and start shooting. For me this is going to completely change how I do my photography work and add in the whole new element of "unrestricted" video and photography movement. I really hope they keep supporting this platform with upgradeable cameras or support for third party cameras as well. If not, the S1000 would be a nice platform as well.

Keep up the great work and thank you so much for the tutorials.

Thanks Ninja!   You're going to absolutely LOVE it!  The freedom and creativity it opens up is awesome.   

I've spent years shooting from the ground and worked with camera cranes, dollies and steadicams but never had as much fun and it's never been as easy as shooting with the Inspire.   

The idea of just showing up anywhere with this thing I just threw in the back of the car and getting the shots is incredible.  

So have fun with it and post some clips when you get it!

All the best,

Jim

Aliasing can be hit and miss.  If you're shooting grass or something with tons of fine detail like gravel, it doesn't take much for a shot to be ruined.

Did you see my troubled footage tutorial?  I have some shots from the same location and some are glorious and some are beyond awful, due to aliasing.

Proper exposure plays a role since having to raise luminance levels during editing can bring out the worst in an image.

Can you post some stills or short clips of the problem?  Does happen a lot or just on fine detail?

Hi Jim,
Thanks for taking the time to reply.

I put a whole series of samples with different settings in my dropbox today. This is after the FW Upgrade. I'm convinced the sharpness settings have been changed in the Update. Where -1 was already very soft before it's now more like -3, and even that is still sharper. But the setting is in finer increments. All Exposures were at EV 0
The aliasing I had with previous settings was also very noticable on rooflines, corrugated iron roofs and the like.
https://www.dropbox.com/sh/90nit ... 3Q2sZz9m1C1cpa?dl=0

The flying is rip, sh.. and bust to get as many tests out of one battery, but I think it tells the story.

Hi Jim,
Thanks for taking the time to reply.

Are you sure you meant aliasing and not artifacting?   There is no way the compression would be able to keep up with that scenery at those speeds so your tests just reconfirm that.

Have you tried it in "normal" circumstances?   

I know exactly how to make the camera fail and am careful not to overstimulate it.

Here is a link to a file with settings 0,0,0 in custom, shot prior to the latest FW update.
Just uploading now. https://www.dropbox.com/sh/qy7ts ... jmUKJsmFqlbDHa?dl=0
These are normal circumstances - and there is a lot of aliasing alongt he roflines, fences etc.
I was getting a lot of this in the other scenery even at low speeds.

In the Dropbox Playback Stream it looks more like artefacts indeed. The raw file looks quite different.
Thanks again

Regarding Final Cut Pro x, it's difficult to say.   If your only use is Inspire footage for fun it's probably overkill, not to mention expensive.   As a powerful professional editing tool it's invaluable and worth 10 x what they charge.   

If you spend some time learning the free version of DaViinci Resolve then you can make your clips look amazing and cut them together with something that costs a lot less, like Premiere Elements or even iMovie.

Hi Jim. From my research and your comments, Final Cut Pro seems to be the dogs doodahs. My wife has offered to treat me so I think I'll  take her up on the offer. No doubt she has her eye on a new pair of shoes which she'll just slip into conversation over the next few days!!

By the way, from experience, 3 x TB 48's are apparently the equivalent in brownie points to a pair of Jimmy Choo's and a handbag!!!! ..............................Go figure???
