Does this Include any improvements on Playback Scrubbing? That is the biggest Pain so far at using this camera. Especially if filming at higher frame rates it’s extremely hard to find the moment of interest.

Playback Scrubbing is currently in development and testing, and is expected to be included in the next update.

Awesome! Great to see the SDI port ready to use.

I don’t have my rig with me right now, so just a quick question: can HDMI and SDI be used at the same time? And do both outputs support up to 4K?

Also curious if the HDMI and SDI resolutions can be set independently, or if they have to match.

hi,

thanks for the update.

what about 25P and 50p monitoring… ?

a lot of people are using those frame rates .

thanks

Great to hear that SDI is working. Looking forward to recieve my Spark soon - working with highspeed cameras for nearly 20 years. 

One (or two) more suggestions regarding SDI & Playback workflow:

  1. Will other SDI & HDMI Framerates be implemented in the future? Meaning all standard frame rates - 23.976, 24, 25, 29.97, 30, 48, 50, 59.94 and 60p. This would be very important to let the playback be in the right speed and framerate, which the actual shot is imagined. In an ideal world I would set a Project Framerate (one of the above frame rates) in the Menu and the Video Outputs would be set to that frame rate and the Projectframerate is also written in the metadata of the files, so it´s already set right in the Pixboom Cine Software for conversion. With just 60 or 30p available the playback would be faster on the monitors than I actually want it to be, if I´m shooting e.g. for European countries with 25p project frame rate. And the directors want to see the actual speed in the playback - not after converting files half an hour later…

  2. Playback: Scrubbing with the Jog wheel in futures updates sounds great. I would also wish to have the possibility to set an In & Out point on the timeline (maybe with the two FN buttons when I´m in the Playback mode) and to have the possibility to set a “Loop Marker” somewhere - meaning the playback would loop from the set In Point to Out Point. So only the relevant part of the recorded clip gets played and will loop, so I don´t have to start the playback manually all the time.

That’s amazing news!! 

feature requests:

  1. displaying settings and record indicator via SDI and HDMi. Looks like monitor can only output a clean feed right now.

  2. Log video output that matches the BMD Film Log in resolve 

  3. Internal false color and clipping indicator 

Very excited to see this camera grow. I’ve been very impressed by the image so far!! 

thank you!!

Great few notes:
max 4x speed playback is not enough (by far) it takes too long to get to the moment.
Scrubbing timeline thingy on the screen is too short - would be better to have it full screen width, so it’s easier to get initial position.
If using finger only it’s hard to get to exact moment on higher framerate shoots, I keep jumping either before or after the moment I want to capture. But then if i playback even at 4x speed it takes too long. Maybe having multi speed finger scrubbing somehow help? Maybe getting approx location first and then some way to switch to more precise scrubbing.

Thank you for all the updates and good luck developing!

A delete function for unwanted clips directly in the camera.

Trimming of clips directly in the camera. Because in the field you don’t always have access to a computer, and storage space runs out quickly far from civilization.

when is 12 bit coming out 

When will dead pixels be resolved?

Would love to see the sensor calibration tools the community is speaking about and also deleting clips in camera.

Is the FTP file download feature available? Will it be added in the future? If so, when?

I haven’t received my camera yet, expecting it by the end of the month. That is an absolute must to be able to delete unwanted clips on the drive. Can’t believe this feature isn’t available!

Quoting Young,…

Formatting is better as deleting files directly in camera to free up space can create fragmented files over time, which will affect the write speed of cards.

On my RED, it’s not possible to delete files either. I do hope that future updates will allow us to mark in and out sections which we could save as a new clip within the camera. 

Firmware Version 1.1.0 Feedback

Overall Impression

Firmware version 1.1 includes some excellent improvements—particularly scroll-wheel support and simultaneous HDMI and SDI output. However, several physical controls remain inconsistent across the interface, and some important features for professional workflows are still missing.

Unfortunately, I was unable to test the SDI port at this moment since I am away from my monitors. However I will do that this coming week. I plan on mounting a in-line Mutiny X2 ISO to protect my SDI port from being damaged from incorrect connections. 

Currently Pixboom has no warning’s described in their manual to prevent SDI board damage.This is essential as 12G SDI is very sensitive to voltage spikes caused by unshielded, ungrounded, or just poorly connected external monitors etc. This is NOT a Pixboom, Red, or Arri Problem this is a 12G SDI reality.

I sent in a RED Komodo just last month for a blown SDI port because one of my AC’s didn’t follow the Last in First out rules. It’s one of those problems that can seem unnecessary until the conditions align to really screw up your day.

Ok, on to my run down of the new firmware :-) 

Bugs and Control Issues

1. Home/Live Button

The physical Home/Live button works from the Home and Live screens, but it does not work while navigating menus.

Requested change: Make the Home/Live button functional throughout the entire interface. It should act as an escape button that immediately returns the camera to the Live screen, ready for filming.

2. Function Buttons on the Home Screen

The Function 1 and Function 2 buttons work while viewing the Live screen but not from the Home screen.

For example, I assigned FN1 and FN2 to adjust shutter speed. Although the shutter information is visible on the Home screen, pressing the assigned buttons there does not change it.

Requested change: Allow assigned FN buttons to work consistently from both the Home and Live screens. Some operators may prefer to leave the Home screen displayed while using an external monitor for image viewing.

3. Zoom Transition Glitch

The 4× Zoom feature is very useful for checking focus. However, exiting Zoom briefly displays a glitched or interlaced-looking frame.

Requested change: Provide a clean transition from the magnified view back to the full image.

4. Exiting Clip Playback

During clip playback, neither the Home/Live button nor the Menu/Back button has any effect. Currently, the Play button is the only way to exit playback.

Requested changes:

  • Home/Live should exit playback and return directly to the Live screen.
  • Menu/Back should exit playback and open the menu.

5. EF Lens Information

With a Sigma 18–35mm EF lens attached, opening the lens-information screen caused the camera to freeze briefly. After several attempts, the lens information eventually appeared correctly.

No change, just highlighting something that happened. 

6. UART Display Glitch

The display briefly glitched the first time UART control was changed to EXT. The problem has not occurred again.

No change, just highlighting something that happened. 

Firmware Feature Requests

High Priority

1. Reel and Clip Naming

The camera continues to label recordings with repeating names such as A001…C001. This creates serious file-management problems in professional productions, especially on multi-camera shoots.

Requested options:

  • Assignable reel letters and numbers
  • Sequential clip numbering
  • At minimum, a unique filename for every recording that does not have Reel letter and Clip numbers. 

Unique filenames are essential to prevent duplicate names and make footage easier to organize, transfer, conform, and archive. 

Having this Reel Letter & Clip number is a standard part of any film crew work flow and it is very disruptive to the process to have a camera writing only A001C001 to every clip. So far this has been a 20 minute long discussion on every set I have shot on so far with it on how to handle these files. 

If providing this ability is beyond what your team can do right now, I suggest you remove the reel / clip labeling and just do unique file names per take… While I would 100% rather have the standard way, doing it the half in half out way is a problem for us. 

2. Longer Pre-Record Duration

At UHD 4K and approximately 937 fps, the current setting provides about 3.3 seconds of usable pre-recording.

Suggested targets:

  • Minimum: 5 seconds
  • Preferred: 10–30 seconds
  • Ideal: Longer, user-selectable durations when technically possible

Example use case: During a spec commercial shoot, we filmed an object falling into frame. It needed to land with its branding facing the camera perfectly. The camera remained static, resets were quick, and we ultimately recorded more than 70 takes to obtain two usable shots.

With 20–30 seconds of pre-recording, we could have repeated the drop continuously and pressed Record only after seeing the object land correctly. This would have dramatically reduced the number of unnecessary clips and the amount of footage requiring transfer, review, and storage.

3. Speed-Sensitive Scroll-Wheel Scrubbing

The scroll wheel is helpful for precise frame selection, but it is currently too slow for navigating high-frame-rate footage.

Requested change: Add speed-sensitive or accelerated scrolling:

  • Slow wheel movement should advance frame by frame.
  • Faster wheel movement should scrub rapidly through the clip.

This would preserve precision while making long or high-frame-rate clips much faster to review.

Lower Priority

1. Save and Restore User Profiles

Firmware updates currently require users to rebuild their camera settings, including run/stop controls, white balance, frame rates, resolutions, and custom presets.

Requested change: Allow complete camera configurations to be saved and restored, ideally through exportable user-profile files. Profiles should persist through firmware updates whenever possible.

Positive Improvements

  • Scroll-wheel navigation and selection are now functional—thank you!
  • Pressing Record from a menu immediately opens the Live view and begins recording.
  • The 4× Zoom feature is useful for focus verification.
  • HDMI and SDI outputs can now be enabled simultaneously.

Since Pixboom has not published any guidance, I would treat the Spark like any other modern 12G-SDI cinema camera:

  1. Mount batteries on both the camera and the monitor/transmitter.
  2. Connect power to both devices first.
  3. Then connect the SDI cable.
  4. If changing batteries on either device and the accessory will lose power:Disconnect the SDI cable first.Change the battery.Restore power.Reconnect the SDI cable.
  5. Disconnect the SDI cable first.
  6. Change the battery.
  7. Restore power.
  8. Reconnect the SDI cable.
  9. Avoid powering accessories from unstable or poorly regulated D-Tap outputs whenever possible.

Ohhhh I love the idea of the Marker. 

What if they use the function of pressing in on the Jog wheel to activate a marker. Then that marker syncs with Pixboom Cine and you already have a in / outs set on that clip. 

There is a lot of times I review the clip in camera for the client to see… and likely it will be one of these that we actual export at the end of the day.

I am on the fence about a delete function, most cinema cameras do not allow this and for good reasons… Just my thoughts.

FTP download : That made me laugh a little. Can you imagine sending over FTP a full slow mo clip…

Jokes a side, If they did implement a proxy side car file, then that would be perfect to have uploaded. However instead of FTP, I would rather them integrate a normal camera to cloud process.
