FWIW, I started experimenting with stuff. First try: I hooked up a Fotasy ($115) EOS-m43, put my old Nikkor 50mm f1.4 on it, and shot a low-rent PR vid with it.
I stopped down to f2. Not bad. As mentioned before, I'm not terribly discriminating about bokeh, just want shallow DOF to really knock away background. That said, bokeh's a bit busy, but I'm encouraged.
My next step involves a cheap Chinese speed-booster and the FD mount with a 55mm f1.2. We'll see how that goes. More than anything, I think I appreciate the idea of buying two cheap primes, a speed-booster, a dummy adapter, and then getting 4 focal lengths out of the deal.
Whenever I can do more with less, I like that.
The Fotasy dummy adapter was $115? Why so much?

Thanks, I have an upcoming project the FZ1000 should be perfect for.

Well, how many minutes, on average, will a 64gb card store?

5 Axis Hybrid OIS is also used in the FZ1000. It is a combination of Optical IS and electronic stabilisation. No sensor movement is involved. So if it works the same in the GX8, that means no sensor stabilisation in video mode (like the GX7).
This is off topic, but do you have the FZ1000? If so, how do you like it. It may be my first foray into 4K when the price drops below $500. If you do have it and have a couple secs, can you give a basic pros and cons list? I have seen some videos and I love the downsampled 4K to 1080p. I am aware of the 4K crop factor, how is the stabilization? And anything else you can think of.

I just got the email.
I downloaded Hitfilm 2 Express for free when they had the offer last year, but I never really tested it out.
Has anyone used it?
-
Nice specs. I look forward to picking this up next year when the price drops.

The headline feature of XV10 is that it's 4K. Yet, footage after footage that's been posted to date has been soft, like it's a HD DSLR. Still, we have have ardent supporters ignoring both the specs and the results and vigorously defending it. It's either an overpowering brand loyalty or a contrarian attitude that simply wants to go against the majority view. Reminds me of an evolution debate where the creationist hears a five minute listing of facts supporting evolution and responds with "I don't believe it." Touche. Seems pointless to engage in XC10 discussions till we have much more footage/results/experiences.
I defend it because it's 4K looks more filmic to me. Most 4K footage, I have seen, looks very "videoey," to me.

In my opinion these are the main reasons against the a5100:-to small for my hands
-body is getting pretty hot after using it in video mode after only 3 minutes
-no function buttons, you have to configure everything over the menu
-no external mic jack
-no view finder
I'm still a beginner and do not have a lot of experience, but these features are pretty important and the a5100 dont have it.
- Are you recording long takes? Because, I have the a5100 and have used it in the hot, summer sun and have never had an issue with it overheating. Although, I have heard that it is a problem.
- You can go into the menu and set any of the external buttons to do any of the manual functions you want. For instance, I set the ? Button to work for zebras. I set the up button for white balance and the left button for creative styles, etc, etc...
- Yes, I wish it had an external microphone jack.
- And a viewfinder would be helpful, but since I use focus peaking, combined with magnification... a viewfinder isn't necessary.
Anyway, if you want 4K, then go for the G7. If not, either of the other two should work well, just remember you have a larger crop factor with the Panasonic cameras, not a big deal if you plan on using modern m4/3rds lenses, but if you intend on using vintage glass, without some version of a speedbooster, then your wide angle 28mm lens, becomes a 56mm lens. Your 50mm normal lens becomes a 100mm telephoto lens, etc, etc...
Good Luck with you choice.

You can select individual clips and transcode them. I'll look again to see if there's an option to transcode the clips in the timeline automatically. You could be right though that it transcodes the entire original file, (not just the section in the timeline).
I'm not sure though that transcoding is even necessary. The only time I've ever seen it remove codec issues was with the mark 1 omd em-5 footage, which would become really macro-blocky sometimes if you edited it natively. With other cams I've occasionally tested this, transcoding one clip in the timeline but not the others, and I've never been able to see a difference. I guess if your media is fast enough to handle the increased amount of data, then editing transcoded footage should be lighter on the processor. But I'm always amazed at how well fcpx performs, even on lowend laptops. I was playing with someone else's 100 Mbit GH4 footage, and even that worked ok on the Air.
By no means am I an expert about these things, but I believe the point of transcoding is so you are not editing the heavily compressed, original file. I believe the native, compressed files are recorded in a manner where not all of the information, for every frame, is recorded. When the file is transcoded to prores or other intermediary codec, that information is expanded for every frame, giving you larger file sizes to work with but also making it less taxing on your system. I am new to FCPX but I believe if you have optimizing unchecked and proxy unchecked, then you are working on the native files and not until those files are rendered, or exported, will they be transcoded to whatever you delineate as your delivery codec.
At least that's how I understand it, but again, I am relatively new to post... So I may be wrong.
-
About transcoding, if your NLE takes XAVC-S natively (which it probably does, it's a pretty supported codec by now) Nothing beats editing and grading the native file, only transcode when your computer is not powerful enough to edit the native footage so ProRes/DNxHD is much lighter for the machine. Transcoding is a cumbersome process that takes time and effort and is best avoided if you can edit the native files.
I guess it depends on how much post work you do and what you're doing it for. If you're just making a couple edits and uploading to a website, then yeah... No need to transcode. But if you're doing a heavy grade and adding extensive effects, then transcode.
-
I've just checked my settings, I have transcoding turned off for import in FCPX. I think it's just the clips that I drop into the timeline that get transcoded (although.... when I look at video info for a clip in the timeline it says that only the original is available)
I think that means you are editing in the native format.
-
I just emailed Divergent Media, the makers of EditReady, and they claim their program will work with the XAVS-C files from the a5100 and the firmware updated a6000. I am going to download the free trial tomorrow and test it out.
I'm interested in seeing how the metadata functions work in that program and the LUT applications
Sorry to the OP for hijacking the thread.

Fcpx transcodes everything to prores on import anyway. I'm curious, why do you want to transcode before import? XAVCS in fcpx is seamless, even on the lowest spec MacBook Air.
Honestly, I don't have an answer for you. I know FCPX would do it, in fact I could only watch the files on my computer via iMovie or FCPX. I remember reading somewhere, a while ago, that it was better to convert before you bring it into FCX and then choose not to optimize in FC, and you would get a cleaner, quicker conversion. Since then I have read that you cannot set IN and OUT points while importing through FCPX? I don't ingest every second of every clip, I only transcode and import what I need.

Like I said, I got mine in the mail the other day and I have filmed about 5 minutes of tests with it and so far I am really happy with it. My other camera is an eos-m, and I have duplicates of a Minolta MD 50mm f2, nice underrated lens btw, and I think I may do a side by side test between the two. I was always happy with the eos-m but now I am curious to see how the a5100 stacks up.
-
Bigger sensor but also bigger megapixel count.. so the noise and DR is about the same in both cameras.
The evf on the GX7 is pretty crap imo but because its tiltable you can actually use it in a unique way by getting a Manfrotto Pixi http://ecx.images-amazon.com/images/I/81M38qFcN-L._SL1500_.jpg you can rest the legs against your chest and rotate the camera's EVF up so you can look into it comfortably and get stable shots.
That's how this was made
I assume this is your video? Great job... It looks beautiful!!! Very nice!!!

It isn't a second camera for a C300/500 since the image quality is dramatically inferior. That pretty much destroys it's supposed main advantage.
Shooting in HD limits you to 50 mbps at 60p, and 35 mbps at 30p. Something like the NX1 can shoot HD at 80mbps at 60p, and 60 mbps at 30p, using a more efficient codec. Some of the bandwidth of the XC10 will be sacrificed to support 10 bits and 4:2:2 as well, so relatively speaking even more resolution information is lost. The Canon codec isn't "broadcast approved" either, it is simply a format that can be readily transcoded, that is all. But so can all of the other codecs out there.
Why are you so angry at this camera?

Haha, by "governor" I was referring to a device that keeps motors and mechanics from exceeding certain speeds or power. In this instance it would control altitude.
-
Can I use xavcs for 60p on the a5100?
Yes, 24p, 30p and 60p.
-
If possible, they should implement an altitude governor for drones.

4k to 1080
In: Cameras
There are many ''algorithms'' for downsampling, and the best ones (cubic & Lanczos) are used in your NLE when you put 4K footage on a 1080p timelime or when you render 4K timeline to 1080p. Don't worry there isn't a better way.
Why wouldn't you transcode before you bring it into your NLE?
-
I just picked up a manufacturer refurb a5100 for next to nothing and I couldn't be happier. The 50mbps XAVSC is amazing. Good dynamic range for s camera at this price point as well.

I tried resolve lite for a brief period... I found it too convoluted. Soon after, I downloaded the free trial of FCPX, and haven't looked back... In fact, I am just going to delete the entire program from my computer. Don't get me wrong, I'm sure Resolve has more color controls, but for basic grades FCPX is more than enough... I may get Color Finale just to have a couple extra options.

Oh, I didn't know Fotasy made speedboosters... Cool, I'm a big fan of their dummy adapters. Do they have them for a lot of mounts to NEX?
