There is a while i didn't came here, and i always loved this place.

Long story short i made a free video converter based on FFmpeg which can converter to professional and standards codecs with hardware acceleration (Nvenc, QSV, AMF...)

Works on Windows, Mac and Linux.

I started this project in 2013 developing with video editor (that i am also) in broadcast companies.

Here is a link to the website & downloads : https://www.shutterencoder.com

Hope you will enjoy the software.

Happy encoding !

I've recently started to get interested in C mount (CCTV) lens, for they are fast, wide, and cheap. So I wondered, is there any CCTV lens that I could use as a Fisheye (and get the same effect as the Panasonic 8mm f3.5, but faster) ? Here's a few lens I've found looking on the internet :

• Rainbow 3.5mm 1.6

• Tamron 4-12mm 1.2

• Pentax 6mm 1.2 (+ wide conversion lens x0.45)

Wanted effect :

The GH2 exact m4/3 sensor crop is x1.86.

So I would like to get the same widness as the Panasonic 8mm or any 8mm Fisheye (Samyang, Peleng, Rokinon...) :

Panasonic 8mm : 8 x 1.86 = 14.88mm equivalent (no need for ETC mode)

Rainbow 3.5mm : 3.5 x 1.86 = 6.51 -> 6.51 x 2 = 13mm equivalent

Pentax 6mm : 6 x 1.86 = 11.16 -> 11.6 x 2 = 23.2mm equivalent -> 23.2 x 0.45 = 10.44mm equivalent

x 1.86 : GH2 Sensor Crop

x 2 : ETC tele conversion mode crop (to cover vignetting)

x 0.45 : Wide convversion lens

Does that mean we could use any CCTV c mount lens instead of the Panasonic lens to get the wide fisheye effect ?

C mount lens (1/2") work well on the GH2, but I heard that the CS mount lens (1/3") would still have really heavy vignetting because even with the ETC mode it would not cover entirely the GH2 sensor. Is that true ?

Interesting CS mount lens, but 1/3 inch : http://www.ebay.fr/itm/TAMRON-Manual-Iris-CCTV-Lens-3-0-8mm-1-1-0-ASPHERICAL-C-Mount-3-Mega-Pixel-/261248954560?pt=UK_CCTV&hash=item3cd3a6b0c0

I would use the fisheye to film Skateboarding.

Thank you.

82mm filter cost will be $171
http://www.bhphotovideo.com/c/search?Ntt=Tiffen+IRND+82mm&N=0&InitialSearch=yes&sts=ma

Smaller 72-77mm filters are even cheaper (about $80-100)

Same filter in 4"x4" form factor will be $260 ($90 more than 82mm round filter)
http://www.bhphotovideo.com/c/search?Ntt=Tiffen+IRND+4x4&N=0&InitialSearch=yes&sts=ma

If you get 82mm round filter to 4x4" converter

It'll just add $26 and for almost all lenses, even wide, 82mm is more than enough.

Here is small video on importance of IR ND (just remember that it uses extreme 128 ND filter).

I went to film racing event last weekend with my GH3. I've remembered playing with this option on my GH2 but then never require it really. I wanted to give it a go on this event.. and it dosen't activate. I mean it's available and goes to "ON" mode in menu but does not affect picture at all (it's still same focal distance being displayed.)

I have being played it with different manual recording modes and while in preveiw and actuall recording mode. Tried different codecs and resolutions. I've swaped and tried 3 different lenses (20mm lumix, 35-100 lumix and 45olympus). I went to menu and used "Reset" option to bring camera to factory settings. No result

Is there something I'm missing any advices before getting myself introduce to Panasonic customer service :) ?

Thanks

Does anybody know a batch conversion tool that could do that job?

It came without a box, just a padded envelope. The converter and the power supply was wrapped in plastic. The power had an american socket and and type f adapter (just what we use in Sweden). Input voltage is 5-12v.

According to the eBay seller I ordered from (and the manual that came with it) it said to support the following input/output resolutions:

• 480i, 576i, 720p, 1080i @ 50/59,94/60
• 1080p @ 23,98/24/25/29,97/30/50/59,94/60

On the BMCC 2.5K MFT + Zacuto EVF 1080i50/60 worked fine, so did 1080p25/29,97/30. 23,98 and 24p did not. I got "unsupported format" on the Zacuto display (latest firmware).

No big deal for me since I'm shooting 25p, but people who need an adapter and shoot 24p to use with their Zacutos, beware.

EDIT: 23.98 and 24p works on the converter. Hooked it up to my Samsung TV and sure enough, I get an image. Which is weird since the Zacuto manual states 1080p24. Time to contact them.

I can also add that audio passes trough and I get metering on the EVF.

For the money I'm not gonna complain and this will do till I can afford an Alphatron or whatever comes out this year that I will settle on. It's light and will stick easily on your rig with some velcro.

I was wondering if any wide conversion lens could fit on the 14-140mm panasonic lens, like the "Wide Conversion Lens DMW-GWC1" works on the Panasonic 14mm f2.5 ? The thread is 62mm, so would some converters like this work ? http://www.ebay.fr/itm/Impact-DVP-WA65-62-62mm-Wide-Angle-Converter-Lens-/110823536775?pt=Camera_Lenses&hash=item19cd98f887 or http://www.amazon.fr/Olympus-WCON-Convertisseur-grand-angle/dp/B0000511RI

Can be useful if you have some rca only transmitter, or very cheap monitor that you use in situation of possible damage.

as every time I use Wondershare the file converted will not play in QuickTime

Thanks

I have 14mm 2.5, 20mm 1.7, and Ai-s 50mm 1.4. Definitely not interested in Sigma 30mm 2.8.

@shian used 0.7x converter on his Ai-s 50mm 1.4 http://www.personal-view.com/talks/discussion/comment/61642#Comment_61642 Smart idea. Less # of lenses. Easier color grading.

I'm looking for 0.6x converter to turn Ai-s 50mm 1.4 into 30mm 1.7 if one third stop light loss.

Calvision has 3 different flavors for 0.6x converter. No idea which one will work if it works. http://www.cavision.com/optics/industrial/adapters.htm

Any advice is greatly appreciated.

I had bought a macro converter from Siocore for the 37mm filter thread, earlier, and I would like to know how it compares to the one Panasonic is now selling (for more than twice the price).

To allow a comparison, I shot an object with many small details that many people should have access to - a 50 Euro bank note.

The focal length has been set to 42mm (the longest possible with this lens), and I tried to adjust the camera to object distance as narrow as posible, such that the autofocus was displaying a happy green frame. (I guess this distance adjustment method is not much more precise than +- 3mm, but that should be enough.

The center of the shot is aimed at the "roof top" inside the "5" of the "50", I think that is easy to replicate if you want to take another sample shot.

Light source was thermonuclear (the Sun :-), the aperture 10.

The attached image is the full frame as extracted from the raw .RW2 file (the only postprocessing applied while converting the RAW to JPEG was white balancing - no sharpening, no noise reduction or such).

I would be very interested to see results from other macro converters, especially regarding minimal focus distance / minimal object size.
