Re: Video cameras

2018-01-24 Thread Igor PDML-StR 


I've been shooting some videos using Pentax K-7 first, and then K-5iiS.
The link posted by Cotty is a reasonable description of pro's and con's of 
shooting videos with Pentax cameras.


While professional videographers indeed use MF, people who are not used 
to pull focus (and don't have dedicated focus pullers) may have problems 
with shooting e.g. sport events. AF can miss (by jumping on a wrong 
target), but on average it can do better then a person with no experience.


For shooting video with a Pentax DSLR, I have a couple of hints (based on 
the mistakes I've made):


1. Switch exposure metering to the matrix mode (or center-weighted 
matrix), NOT the center mode. Otherwise, you will have wild (and annoying) 
swinging of exposure when you are panning if there are dark and light 
spots.


2. There is only one parameter you can control (at least with K7 and K5): 
aperture. There is, however, an effective exposure time for each of the

frames.
 While with the MF, you might have a desire to enhance the DoF by 
bringing the aperture down, in low light that might result in a slow 
effective exposure time, which would make the video to appear less sharp, 
especially when there is a fast motion (due to the motion blur).


Aldo keep in mind this two limitations:
a) The length of a single video file is limited.
In the highest resolution mode on K-5iiS, it is about 8 minutes.
So, you have to stop and start again, for a new file to start.
Depending on the speed of your SD card, there could be a delay before
you can start (while it is finishing recording the buffered information.)

Which brings up yet another important point: Use a fast SD card!
(Just "class 10" is not sufficient.)


b) Fast heating of the sensor limits the total time you can shoot 
(without stopping). I believe that it is worse with Pentax because 
they are using in-body stabilization, and as a result (because the sensor 
is hung in the air for easy movement), the thermal sink is considerably 
lower. Often, in a room-T environment, the sensor shuts itself down 
after 20-some minutes of being on in the video mode.



HTH,

Igor

Interesting. Here's a page with some details abut shooting video on the K5



From what I have read, it is not possible to use AF during video 
recording on the K5.


This shouldn't in itself be a problem - manual focus is much preferred for 
video. If I shoot video on my Pen F, it is only with manual ficus and 
manual aperture lenses.


If you want to use AF with video, you can obviously buy a camera with AF 
for video, but they are not foolproof.

I still have some genuine HM100 camera files - if you want a look, I can 
WeTransfer you some footage fo appraisal. Let me know.

Incidentally when I came to GFM and made a test documentary excerpt (that never 
flew) I used the HM100. I'll see if I can find it and post it again online

The thing about video is this.

There are still cameras that have video bolted on as an afterthought, more like 
'emergency video provision'. Your iPhone will do better video than these types 
of cameras.

There are genuine hybrid cameras that are reasonably good at stills, and 
reasonably good at video. They tend to be expensive!

There are video cameras that may (or may not) allow you to take stills.

The word here is 'compromise'.

May I make a suggestion? If you want a decent small video camera that will do 
autofocus while shooting, zoom in and out with a fixed zoom lens on the camera, 
and auto aperture - there is a good selection available out there limited only 
by how much you want to spend.

A few years ago I used to have a JVC GY-HM100 camera and it  was brilliant. If 
you could get a good one second hand, you'd love it. EVF to look down and/or 
swing-out LCD panel useful for ageing eyes. AF and AE, a decent zoom lens built 
in and a removable handle with proper XLR inputs on it for a small mic for good 
sound recording. Best of all it chucked out genuine Mov files which could 
easily be converted for editing using software like Mpeg Streamclip. IIRC they 
even were editable natively in Final Cut. Brilliant little camera - streets 
ahead of most amateur cameras which tend to have zillions of options buried in 
menus alongside bewildering buttons that need weeks of reading about in thick 
manuals before you can even switch the damned thing on.

The nice thing about pro video gear is that it has to be easy to switch on and 
then work out of the box because often times that's exactly what happens to it, 
by people that really shouldn't be shooting video... (but that's another 
matter!!)

Here's a link:

<http://pro.jvc.com/prof/attributes/features.jsp?model_id=MDL101845>

Notice the file type it puts out - either MP4 or native MOV files - instantly 
viewable and editable. That's the killer function here - and the quality is 
superb. I used mine as a an action cam, mounting it in cars or on bikes etc - 
because not every action camera mounted needs to be a GoPro.

Note that link is archived - I looked on eekbay and here's one that went for 
400 bucks US:

<https://tinyurl.com/y7mgta2h>

That's a steal.

Or by all means search out a new video camera (camcorders) from a selection 
like this:

<http://www.toptenreviews.com/electronics/photo-video/best-hd-camcorders/>


HTH and good luck!

Limited useasge but so far the exposure is all over the place during

When you say you're not happy how the K5 does video, exactly what is it you're
