Accurate.Video Validate Userguide

Accurate.Video Validate is powerful yet tremendously simple to use. The backbone of the application, the dynamic timeline, is optimized for advanced functionality combined with a UI that is easy to comprehend. This guide will go through the content of AV Validate.

Av Validate Overview

Note that all features and functions described in this guide may not be included in the version you are currently using.


The Accurate.Video timeline represents all the activated content of the asset with frame accuracy. With the ability to zoom in on the timeline you can actually see each individual frame.

The timeline also gives you a perfect overview of all activated audio and subtitle tracks as well as the time based markers that highlight and distinguish portions of the video.


The timeline is separated into rows of tracks to separate different content, and for markers you can create your own unique tracks. The timeline also includes miniature thumbnails of the video to give the user an overview of the content. These thumbnails can be scrubbed to quickly find a specific part of the video.

Furthermore, a big part of the user-friendly UI is the ability to click and highlight all cues. E.g. click on a subtitle or marker cue and you will find yourself positioned on the same frame where the cue starts, hover over it with your cursor and you will get all the information about the cue.

Current time indicator

Your accurate playback position is always represented by the current time indicator. Play the video and you will see it flow gracefully through the timeline, stop the video and it stops immediately. The current time indicator cuts through the entire timeline to make it clear where the marker cues and the audio waveforms are positioned

This powerful tool lets you scrub the video to anywhere at any time, regardless if you are clicking on a specific timecode or if you drag and release the indicator. Timecode inputs, clicking a subtitle/marker cue or using the framestep functions also update the position of the current time indicator instantly.

The current time indicator also visualizes the buffering of the video in a subtle yet distinct way.

Playback functions

With Accurate.Video you have full control over your video on a level of frame detail. Apart from play and pause you also have the ability to framestep one or ten frames back and forth.

Added to this is the ability to change playback speed from the range of 64X speed to negative 16X speed presented by a convenient dropdown menu. All the settings are dynamic and can be changed during playback.

The playback panel also includes a parent volume control and a button to show the video in fullscreen.


Loop Playback

The loop function is very convenient if you want to review a specific portion of your video. With AV Validate you can create your own loop in the easiest way possible by creating an inpoint where the loop should start and an outpoint where the loop should end. After the points are set you simply activate the loop function with the “Loop” button or hotkey “r”.

The playback loops are dynamic and can be changed at any time by dragging the in and outpoints to new positions, even when the video is playing. Click on the loop button again (or hotkey “r) to get out of the loop.

To be able to reach all the functions with ease and to sort out what is relevant for you, the app is divided into different sections. Each section is represented by a tab, and by clicking one of the tabs you will immediately reach the preferred area of the application. These are the tabs that are represented in AV Validate:


Tab - Metadata

The metadata tab contains all you need to know about the asset. Here you find the following information:

  1. Full name of the asset.
  2. The date when the asset was created.
  3. The duration of the video.
  4. The frame rate of the video.
  5. Video resolution.
  6. Video aspect ratio.
  7. The last date when the asset was updated.
  8. Number of audio files ingested.
  9. Number of subtitle files ingested.


Tab - Media

The media tab handles all your preferences and lets you activate the ingested files of your choice. Here you have the following options:

  1. Select what proxy to use.
  2. Toggle muxed audio on/off.
  3. Activate one or multiple available discrete audio files.
  4. Change discrete audio global offset.
  5. Activate one or multiple available subtitle files.


Tab - Audio

The audio tab visualizes the audio of your asset and presents audio meters for all your activated audio channels. Here you also find advanced options to edit and manage the audio meters.


Tab - Markers

With the ability to create and edit markers, you can highlight and distinguish portions of your video. Here you have a list of all your markers and also the following options:

  1. Search for markers by name.
  2. Filter to only show markers from certain marker tracks.
  3. Create markers.
  4. Edit markers.



As mentioned above you have everything you need to differentiate parts of your video with markers and marker tracks. All your created markers are editable and have a wide range of customizability. You can create markers easily with the help of the current time indicator combined with the inpoint and outpoint buttons.

Creating inpoint and outpoints

The inpoint of a marker is plainly the start frame of the specific marker cue, and the outpoint is the last frame of the cue. To create a marker cue you begin by positioning the current time indicator where you want the inpoint to be, and then click on the “Set Inpoint” button. Do the same with the outpoint using the “Set Outpoint” button and you got yourself the start and end of a marker.

With the inpoint and outpoints set you can also instantly jump to their position by using the “Go to inpoint/outpoint” buttons.


Customizing the marker

Now it is time to head over to the marker tab, where you will find the “Create” button. Click on the button and you will see the following options to create a marker cue:


Apart from naming the marker cue and adding a description, you also have the ability to change the inpoint and outpoint from this screen. This is the perfect opportunity to make minor adjustments. You can also see the total duration of the marker cue, and it will change in real time if you adjust the inpoint/outpoints.

The last thing to set before your marker cue is finished is to select what marker track you want it to be situated in. You do this easily with the marker tracks dropdown menu. All the marker tracks are distinguished in separate rows on the timeline, making this a perfect way to sort marker cues in different categories.

Some marker tracks even give the marker cues a separate colour to really make them stand out on the timeline. Here you will also find all your custom marker tracks as options.

When everything is set, just click the create button and watch the magic when the marker cue appears in the marker track you selected on the timeline.

Copy and paste custom markers

Instead of creating the same custom marker multiple times on different marker tracks you can use the copy and paste function. Highlight the marker you want to copy and click on the “Copy marker” button (hotkey “Ctrl+C”), then click on the marker track you want the marker pasted to and click on the “Paste marker” button (hotkey “Ctrl + V”).

You can paste the same copied marker to multiple tracks, and they will always appear on the timeline with the exact same timecode and duration.

Export markers

All the markers you have created can be downloaded to your local storage. Under the Markers tab you will find a button to export all your markers for the asset you are working on. When you export markers you can select if you want them in CSV, XML or JSON format.

Custom marker tracks

The global marker tracks are predefined and created in global marker track settings. With AV Validate you also have the ability to create your own unique custom marker tracks.

Simply click on the “+” next to Marker Tracks to create a new track, and proceed by giving the track a name. You can edit the name of your custom track at any time by clicking on the “pen” icon next to the track that will appear when you hover over it. All custom marker tracks can be deleted by clicking the “trashcan” icon.


Additional functions

The Accurate.Video Validate delivers additional important functions as well. With the dynamic timeline the application is a perfect tool to compare discrete audio tracks and different subtitles. Apart from this AV Validate also includes functions to set a specific start time to an asset, as well as setting a global offset for all your audio files in an instant. Below is a summary of important additional functions:

AWS Rekognition

AWS Rekognition is a powerful analysing tool that can save you a lot of work by detecting certain elements of your video and present them as markers on the timeline. With AV Validate you can use rekognition services on already ingested assets through the "Enrich" action, found under the "more" menu on each asset. Read more about enrich in our AWS Rekognition guide.

Dynamic Panels

With AV Validate you can customize the different panels of the application to better suit your personal workflow. Drag the timeline panel up and down to find your own preferred view. The “Tab” panel can also be adjusted to a wider state to make certain elements more visible. The latter can even be docked all the way down on the right side by clicking the “Dock to side” button.

Comparing audio and subtitles

With the ability to activate all your discrete audio and subtitle files, you can see them lined up and compare them with precision. All the files associated with the asset are just one click away to be activated on the timeline. If you do not want to see a particular audio track or subtitle, just deactivate it. Simple as that!

Global audio offset

The global offset function is a great way to adjust all your audio at the same time. You have probably noticed a video in the past where the audio is a tad off sync. With global offset you can adjust this in seconds. The global offset can be found under the tab settings, and consists of an input field so you can edit the global offset with a precision of milliseconds.

Playback settings

As mentioned before, with AV Validate you have full control over your video. In addition to all the standard playback settings the application also includes advanced playback settings. Click on the cogwheel icon and you gain access to changing the start time of your video. From here you can also toggle dropframe on, which is a lifesaver for video with a certain framerate. Of course you can reset everything to its original state if you change your mind.


AV Validate also includes the ability to search a specific frame based on the timecode. Simply click on the input field, insert your preferred timecode or frame and press enter. The video immediately jumps to the new position.


Multiple proxies

Apart from multiple audio and subtitles, you can also ingest multiple proxies to your asset. This is a good way to compare video quality between proxies. It works similar to discrete audio files and subtitles, changing proxy is only a click away!

Multiple assets

With AV Validate you can open multiple assets at the same time. Simply add a comma (“,”) in the URL followed by the ID of the subsequent assets you want to open. Make sure to also add a comma between each asset you want to include (,44,23,22 for example).

Furthermore you can add additional content from other assets with the URL by writing “&components=” at the end of the URL followed by the ID of the component you want to open. This is a brilliant method to see if certain elements are suitable for the asset you are working with.

Change application instantly

If you want to open your asset with our other player, AV Poster, we have added a convenient dropdown that lets you change application instantly.



Under the user icon in the top right corner you will find the preferences menu. For AV Validate you can select if you want a frame counter activated or not with a toggle on/off. The frame counter feature can be very useful to gain constant control over exactly what frame you are positioned in when working with an asset.

Under preferences you can also change what application you want to open your assets with when you simply click on them. The default preferred application is AV Validate, but you can change this to AV Poster if that suits your workflow better. The preference section also include additional options for AV Poster.

Approve and reject

With AV Validate you can also review and set the status of an asset. In the top menu there is a dropdown that gives you the option to either set the status of “In progress”, “Approved”, or “Rejected”. If you want to remove the status you can easily change back to the "No status" default.


All different statuses have their own unique color, that will be visible both in the dropdown within the particular asset, and also in the asset page where all of your assets are gathered. Green color indicates that the asset is “Approved”, gray indicates “In progress” and red indicates “Rejected”. Below you can see an example of how the status dropdown indicate that the asset is approved:


When you reject an asset you will be asked to comment on why the asset was rejected. The comment will be saved for others to view:



For your convenience AV Validate contains hotkeys for almost every visual button and function. There are also additional hotkeys which give the users even more advanced options. When you get to work with the application you will notice that the hotkeys save a lot of time. Here is the full list of hotkeys:
