Low Bit Rate HDMI cables

If you're using a gaming laptop for a trial presentation, or simply tasked with setting up a monitor capable of 4K or 8K resolution (ultra high definition using 4,000 or 8,000 pixels) you want to keep in mind that an older or even 'high speed' HDMI cable may not be able to support the video at such an elevated resolution.

Standard HDMI cables are no longer widely available at Best Buy or other online stores where you're likely to go to pick one up, but there's no doubt that you may be handed one by a law firm's IT staff, or find one as the cable provided for a courtroom's a/v system. These cables have a bandwidth of 4.95 Gbps and won't be able to support 4K or higher. They are designed for 1080 pixel devices. They will be designated as version 1.0 or 1.2.

You might think that a 'high speed' cable [versions 1.3 to 1.4] would be what you need, but it also won't work with 4K video at higher frames per second. They support 10.2 Gbps but won't support 4K video higher than 30 frames per second.

A Premium High Speed version 2.0 HDMI cable has a bandwidth of 18 Gbps and will work with any 4K video, and some 8K videos at lower frame rates.

If you want to play it safe and be ready for any 8K video at all, secure an Ultra High Speed HDMI version 2.1 cable (48 Gbps).

The Ultra High Speed cable will work fine with lower res videos.

If you are using an HDMI cable that won't support the resolution of the video, you may simply get a lower res video, a video that flickers, or worse yet no signal at all.

Scrolling text hidden behind deposition video in OnCue

Trial techs everywhere have switched to OnCue's trial presentation software, and my experience using it in court has been very positive. It does however have a minor glitch, which I think many will want to be aware of. In version 4.3, if when working in the designation editor, while showing ranges from the same designation list (a list defined as multiple deposition designations for a single deponent) in presentation mode, you toggle off scrolling text for a designation range from the same list by clicking the green arrow / red X lined page icon at the right above the waveform:

. . . and then publish the designation line numbers for the closed captioning text can peek out on the left:

It's a minor problem which can easily be corrected by pressing T to toggle off the scrolling text. Pressing T when you see this error won't bring back the scrolling text first. It clears the hidden cut off text 'behind' the video. If you press T a second time it will display the scrolling text again.

The problem seems to occur, when one designation range from a list has been presented with scrolling text; the scrolling text setting for another designation is turned off; the designation range is cleared from the presentation screen; and then the next designation is presented. If you do NOT clear the previous designation, the error does not occur.

Also keep in mind that if you toggle off the scrolling text for a designation range, the update won't take effect at all unless you first select a different designation range. Just toggling off the text and then publishing the range will leave the closed captioning text in place.

This problem did not happen in all deposition videos I tested, but did frequently reoccur in the videos in the OnCue demo case. I just post here about it, because it's good to be aware of potential problems and not be surprised in the courtroom.

OnCue's designation wizard

It's no secret that attorneys will list deposition designation page and line ranges in a variety of formats. The same attorney may use a page / line range form inconsistently, and of course, even the best lawyers will inevitably enter page and line numbers incorrectly. Like nearly all litigation support professionals, I have spent many hours parsing through lists of designations to put them in the format required by TextMap, Trial Director, and other applications.

Luckily, OnCue's trial presentation software includes a 'Designation Wizard' which can import page and line ranges that have been listed in a variety of forms. Not just loads files in the format used by Lexis TextMap (as discussed in the Tip of the Night for May 5, 2024), or the format used by Sanction, but in almost any random form an attorney might come up with.

In this example, we can see how page line numbers entered with different delimiters (both using common delimiter characters) and common terms used in English), get interpreted as designation ranges by OnCue which then automatically generates designation snippets. If it can't tell that range is intended, it will highlight the unknown range in red:

Even when ranges are entered with extra spaces between page and line numbers, or with different delimiters for a single range, OnCue can still get them correct:

You copy ranges in, or enter them one by one, and the Designation Wizard creates the new video clips almost in realtime.

The Wizard will help you catch mistakes you might have otherwise missed, and get video clips finalized for the next morning faster, so you can get to bed sooner - the key challenge every trial tech faces.
