It's possible to have the black frames removed and earlier frames duplicated.
ffmpeg -i in.mp4 -vf blackframe=0,metadata=select:key=lavfi.blackframe.pblack:value=50:function=less -vsync cfr -c:a copy out.mp4
The blackframe filter analyses and registers the proportion of a frame's pixels which are black. The metadata filter keeps all frames which have at ...
I have that camera. Here are a few things to consider:
The camera doesn't have any in-body stabilization, so the footage can be very shaky unless you're prepared. In my situation, I knew I wanted to use a gimbal to stabilize. This works great, but it will affect your lens choice. If you plan to use the BMPCC on a gimball ever, remember that you won't ...
I've created a thumbnail provider available from here https://github.com/tom-gangemi/braw-thumbnail-provider/releases/tag/v1.0.
All you need to do is extract to your desired install location and run register.cmd.
You can use an SDI Distribution Amplifier ("DA") (one SDI input, and two or more SDI outputs) for each camera so you can "duplicate" the camera video to send to both the production switcher and to your camera iso recorders. I use DAs I buy on Ebay. My current favorite is "AVUE 3G-SDI/HD-SDI/SDI 1 to 2 Repeater & distribution extender with re-clocking" ...
Some DSLRs output HDMI video that does not meet full HDMI specifications. It is not unusual to find combinations of source and destination gear that is incompatible. The HDMI can be viewed on permissive screens (consumer TV receivers, etc.) but not on more professional gear that strictly adheres to the HDMI standard protocols.
You can use Edit > Delete Gaps
This will remove all gaps on all tracks. To exclude a particular track, you can lock the track before you Delete Gaps.
You can also change the default Image/Still duration before the import in the application Preferences > User > General > Standard still duration setting
For most people, the first workhorse lens will be a zoom, because of the versatility.
Sharpness in lenses isn't a huge factor for video; at HD resolution and below, lenses that photographers turn their noses up at for their sharpness do a perfectly adequate job. Once you're shooting 4k it starts being a bit more important, but even still that's way below ...
Make sure none of the SDI outputs of the ATEM are routed back to its inputs.
Talkback feedback loop
The ATEM uses SDI channel 15 and 16 for talkback. If you route one of your SDI outputs to the SDI inputs (either directly via a simple SDI cable or trough a system of devices like record/playback devices) you will get a feedback loop that causes this ...
It indicates that ME 3 PGM is selected since there is no buttons for M/E 3 and 4.
Blackmagic ATEM Front Panel Tutorial
The switcher's front panel doesn't have a button for all routable inputs/outputs. If you click an AUX in the menu of the ATEM Software Control, you can see that you have 60 items in the dropdown, while there are only 36 buttons on the ...
For videography you do not necessarily look for "a good" lens for pixel peeping, you want a good autofocus system and a wide aperture for a "cinematic look".
This depends on what type of videography you are doing. Interviews, documental, landscape, indoors, outdoors, using a tripod, using a handheld. Jason Conrad's answer is interesting because he is using ...
I managed to fix this. It turns out the card was active, but had frozen for some reason. rebooting the machine, something I should have done in the beginning sorted out the problem. Thinks are still not perfect. But my issue is solved. Thanks
As long as you can do the job right, there is no contest here. BMPCC4k all the way. The X-T3 is a nice mid-range photo camera, but it's a still camera first and a video camera second with all the limitations that entails. The BMPCC4K is a very solid entry level digital cinema camera. It lacks the more full featured functionality of it's bigger brothers ...
Going to f/1.8 will brighten up everything, the Screen and the Presenter, and reduce your DOF. With a less expensive Lens your going to be stopping down to get a sharper image; wasting time and money, and not accomplishing what you want.
What you want (I'm guessing) is for the Presenter to be better lit, presumably you can see the Screen (otherwise you have ...
You will need an app or chart for the calculation. There are apps on both iOS and Android for this. Just search depth of field calculator.
With a 50mm lens shooting at f/1.8 you're depth of field will be very shallow; more so the closer your subject is to the camera, with your DOF becoming deeper if your subject moves away.
Some lenses have a built in ...
Using embedded (or omitting -audio_input) is the intended way to get the audio of HDMI or SDI signals.
Please make sure that there is a 2ch-stereo audio signal on HDMI. If it is 5.1 or 7.1 you might have to use -channels 8 in the commandline before the -i.
Note: please pay attention to the pix_fmt warning. Leave that option out of your commandline.
As the docs say,
you need the Blackmagic DeckLink SDK and you need to configure with
the appropriate --extra-cflags and --extra-ldflags. On Windows, you
need to run the IDL files through widl
If so, run
ffmpeg -re -i rtmp://server/live/streamname -c:v rawvideo -pix_fmt uyvy422 -vf scale=720x576 -c:a pcm_s16le -ar 48000 -ac 2 -f decklink "Device"
Which Lilliput monitor do you have and what exactly is the output format of the 5d Mkiii?
Not all Lilliput screens can display progressive resolutions. Sometimes cameras provide "fake" interlaced on the monitor out (PsF) even if recording progressive to avoid that problem. It is a common problem with the BM Pocket Cinema Camera and (some) Lilliput screens ...
The page you want to look at is the "Capture and Playback" page of the Blackmagic Products page. Any device on that page that says "four analog audio inputs" is a good bet. Media Express does indeed have the ability to record audio and video from an SDI input, and also audio-only from audio-only inputs, giving you a multichannel media file that you can ...
