Video Timecode

[Berniece Domnick]

Atimecode (alternatively, time code) is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production, show control and other applications which require temporal coordination or logging of recording or actions.

In video production and filmmaking, SMPTE timecode is used extensively for synchronization, and for logging and identifying material in recorded media. During filmmaking or video production shoot, the camera assistant will typically log the start and end timecodes of shots, and the data generated will be sent on to the editorial department for use in referencing those shots. This shot-logging process was traditionally done by hand using pen and paper, but is now typically done using shot-logging software running on a laptop computer that is connected to the timecode generator or the camera itself.

When it comes time to bring all of your audio and video footage into your editing software, making sure that it is all perfectly in sync can be a huge pain. Not only can it be an incredibly tedious and time-consuming process, but you can also end up with less-than-perfect results quite easily. This is the problem that timecode solves.

Timecode is a media synchronisation system that is designed to perfectly synchronise your audio and video recordings. As its name suggests, timecode takes the form of a sequence of numbers that can be attached to video and audio files in order to precisely label their timing, right down to the individual video frame.

The industry standard for timecode is known as SMPTE timecode (Society of Motion Picture and Television Engineers) and is typically represented in the format HH:MM:SS:FF (hours, minutes, seconds and frames).

This timecode information is recorded to your video and audio files either directly as metadata or as an audio track that can later be interpreted by software. Ideally, all of your video and audio recording devices will receive their timecode information from the same source (a timecode generator) so that they can be synchronised to a singular clock.

Once your video and audio files are imported into your video editing software and synchronised using their timecode information, they will be laid out on the timeline so that they line up precisely, even if the files start and stop at different times.

For these more complex projects, timecode serves as both a workflow tool to save you time in the editing process as well as a single source of truth for referencing specific scenes, moments or timestamps within your project, which is especially critical when working with more than one person.

A timecode sync device, on the other hand, is a device that can receive a timecode signal, make sense of it, and adjust its own internal clock accordingly. There are also some devices that are both a source and sync device at once.

Real Time, also known as Time-of-Day, is a timecode format that uses the actual time in your region to fill out the hours, minutes and seconds in your timecode. This format is ideal for organising your footage and recordings as you can quickly see exactly when it was taken in the day.

Another option is to use continuous timecode, which takes the same 8-digit format, but rather than follow your local time zone, you can start the zero point whenever you want, which can be useful if you want it to line up with the start of your shoot. With the Wireless PRO, you set this point within RDE Central.

Mode 1 is the most versatile option and will suit the majority of use cases. It lets you record both audio and timecode to your camera at once, with timecode on the right channel and audio on the left.

Many devices that output timecode, such as the Wireless PRO, produce linear timecode (LTC). This is an industry standard that encodes the timecode information as an audio signal for your equipment to read. If you were to listen to it, you would hear a stream of digital noise.

When comparing the accuracies of the internal clocks in two different devices, there will always be a very slight difference. No matter how small this inaccuracy may be, over time it builds up and eventually results in different timecode readings between the two devices.

There are a few ways that you can avoid drift. The first, and most effective, is to shoot with a camera that supports timecode. When fed a continuous timecode signal, a camera that supports timecode will listen to this external clock instead of its own, remaining perfectly synchronised to the source device.

However, each time you start a new recording, that start point will be perfectly synchronised to the timecode from your source device. This means that drift will be less of an issue the more often you start new recordings.

Even if you do have some drift, timecode is still a huge help when laying out your edit timeline in post-production. You may just need to nudge some of your clips by a frame or two to get them perfectly synchronised.

So when you lay down your audio on the timeline it will snap to the nearest frame, but this position may be thousands of samples away from where it should be. This will depend on the exact point within a frame that the audio started recording.

I'm new here. I'm currently finishing the e-learning for MA3 (onpc). I have no experience with earlier MA products but I'm looking to get into the wonder world of MAlighting Overall the functions that I want to use within MA3 onpc are clear to me and very usefull. Only 2 topics are unclear for me. I want to start with a midi controller instead of the big investment for a wing. I've seen methods how to achieve that but I did not see anything about how to achieve Timecode in/out over ArtNet or even Midi for the on pc software. Maybe there is already but I could not find it after a long search. Does anyone of you use timecode over Artnet and/or do you know where to find more information about this topic?

Thanks in advance!

(ps if there is already a thread about this please let me know then I will delete this one)

I'm sure there are apps out there but I made myself a quick and dirty ArtNetTimecode sender that outputs the current time of day as a broadcast and once I configured OnPC to receive it worked out of the box.

TC slot for the MIDI input is set in Menu -> Output Configuration. Note that if you're using onPC without a command wing there isn't a way in v1.0.0.3 to tell onPC what other MIDI driver it should be looking at.

Is there a way to have a multicam clip use the original source timecode (like in Avid)? I see how to get it to display it as an overlay, but what I need to be able to do is just type in the timecode from the ORIGINAL clip and have it jump to that point. Right now every MC clip starts at timecode zero, and the only way I see is to manually play the clip until the TC I need is displayed, which is a major PITA.

On a side note, Premiere Pro doesn't have "multicam clips". Rather, nested sequence are used to achieve multicam functionality. It's more than a semantic difference, as clips and sequences are different things.

Yeah, thanks for the advice. I also coming from an Avid background but having used Prmeiere for 9 or 10 years find Premiere Pro to be SO clunky with multicam. SO i have a client who strung an A roll sequence together but just did one cam cos he didn't know how to sync everything up. For me having done so now i should be easy to come in and replace those edits with multcam goodness but NO WAY. it's a major pain in the ass cos there's no reference to the source time code. Sorry but that's total BS. Not dissing abyone on this post-I appreciate the help. Just think Adobe need to rethink their multicam workflow fundamentally because it is so clunky.

The text filter in Shotcut #timecode# and how you can place it on any portion of the Shotcut video is perfect, I am just trying to figure out how to format it into ss.xx (seconds and centi-econd) for a short period of time or mm:ss.xx (minutes, seconds and centiseconds) for a longer period of time less than one hour.

Can you elaborate. You want timecode as metadata in the exr or as a burn in or some sort? Where is the TC coming from? Do you want the current TC UE is using or recorded TC from some sort of performance capture?

I generated a black screen via Media Generator and then i applied the "timecode" effect on the video. Then i right-clicked and inserted an envelope on it called "velocity" and nothing changes even if i make it 400% faster than normal. By nothing changed i mean that the timer still went forward counting seconds normally and not faster or slow. I also tried making it 0% but that didn't work either, it didn't stop. What am i doing wrong?

(everything else works completely fine and I'm doing this on Sony Vegas 17, if that helps)

The duration field type is a numeric field type intended for use with time durations measured in hours, minutes, seconds, or milliseconds. Depending on the format of the duration field, the values ...

Hello I am new to Airtable and really like it so far. I am particularly interested in using it in the world of video/digital asset management. Is there a road map to introduce some kind of time code calculator?

Airtable now offers a Duration field type that is available in beta. A duration field can be used for video timecodes measured in seconds or milliseconds, as well as for event lengths in hours and minutes. To sign up for early access to the Duration field type, please visit our beta signup form.

Does anyone know why this is so problematic in Premiere? If I add the time code effect to the clip itself it will read the correct time code but the problem with that is that the timecode burn window changes size depending on the size of the clip and my timeline is all 4k media in a 19201080 sequence in which many clips are size adjusted so it causes the timecode burn to adjust size.
