A review session is a collection of media on which collaborators can leave their feedback. It can only be accessed at specific times through uniquely generated invites sent to each collaborator.

After following the special link in the invite, a collaborator is presented with the review page.

Tip: The user interface for review collaborators works just as well on the go as it does on desktop, with mobile/touch device support.


Clicking an item in the playlist at the bottom will play/display the selected video, image or PDF.

Use the on screen controls to play/pause media or to jump to a specific time in the currently loaded media. In addition, clicking on the playing media will cause it to pause.

Tip: Use the following keyboard shortcuts to speed up your work:

Feedback added to a video clip is visible as colored circles on the timeline. This makes it easy to see which portions of the video have the most feedback and who has commented, as each collaborator is associated with their own color. You can find out which collaborator is assigned which color by looking at the left edge of the comment in the feedback panel.

Clicking any of the left or right arrows at either side of the viewing area will navigate between the items on the timeline.

Switch version

If there are multiple versions of the shared media it is possible to switch between those versions.

Compare mode

Compare mode enables a quick side-by-side comparison of two different versions of media.

To activate compare mode, go to the version selector. If there are multiple versions of the same asset available, you can select "Compare versions". Selecting “compare versions” will change the player to load both versions, allowing you to display both versions side by side or overlaid.

(New in 4.6) You can also choose Overlay which will change the player to display the versions on top of each other. You can use the slider to update opacity and fade between the versions.

Select playback, rate and loop options

You can change how videos are played by changing the Playback option:

  • Play one: one video clip will be played.

  • Play all: play all video clips in your playlist.

  • Play selection: select what to play.

The loop options allows you to control if the video clip is played once or loops.

The playback speed allows you to set the rate and you can choose speeds from 0.25x up to 2x.

Set in and out points

Focus on specific sections of your media using in-and-out loop points. Press "I" and "O" to quickly set your loop points and your video will cycle through those timecode locations. Press "C" to clear the selection.

Select resolution

Uploading files to ftrack generates multiple proxies so that you can review your media in as high a resolution as possible. You can change the resolution if you wish to.

Synced reviews

Sync sessions in ftrack Review display all actions taken on all participants' screens. Skip forwards, jump to a frame, or make an annotation, and your collaborators see the same changes on their screen in real-time.

Sync sessions keep all participants creatively aligned as collaborators can watch one another's actions and notations, as they occur.

To commence a sync'd review session, click the "Start sync" button. Your remote collaborator must then click "Join sync" on their interface.

Once the remote collaborator joins the sync session, the review session will enter sync mode. In sync mode, every interaction synchronizes, and participants will see interactions occur simultaneously across all screens. (I.e., every media change, frame change, zoom interaction, page change, annotation, etc.)

Hover over a collaborator to display their name and if they are currently “online” or “in sync”

Sync participants will not see your cursor. The "Laser pointer" tool enables you to highlight areas of interest without annotations.

When someone starts to type in a comment, the sync session will temporarily pause for that collaborator. Once they post the note, the collaborator will return to sync.

You can sync with a maximum of two participants. If you wish to sync with up to a maximum of 10 participants, you can upgrade to Review Pro.

Tip: Use your phone or favorite Voice over IP (VOIP) provider to perform live and interactive discussions while in sync.

Limitation: Sync functionality is currently unavailable on mobile devices.


Feedback can be added at any time by writing a comment in the text field below the viewer or by annotating the currently displayed video or image using the annotation tools. Display the annotation tools by clicking the brush at the right in the comment field. It''s also possible to add attachments to the feedback.

Annotations made on a frame will automatically be attached as a file to a comment upon submit.

A collaborator can also mark an item as either approved or requiring changes by toggling the relevant status buttons.

Note: Each collaborator has their own approval status for each item in the timeline so no need to worry about disagreements between collaborators!

Tip: Annotations can also be enabled via the keyboard shortcuts:

Zoom and pan

Zooming and panning can be done using the Zoom and Pan tools in the interface.

Tip: Zoom and Pan can be activated via keyboard shortcuts:

Tip: you can pan media by holding down the middle mouse button.

Read feedback

You can read feedback already given on the media in the right side pane. Here you can also sort the feedback chronologically or by the videos frame number or PDF page.

Clicking on a page or frame number on the note will take you directly to that position in timeline.


If downloads are enabled by the creator of the review, a download button will appear next to the viewer tools. The original file together with the compressed version can be downloaded if they are available.

Browser support

We try to ensure that client reviews works in as many browsers as possible, but in order to deliver advanced functionality such as annotations we utilize features that are only available in modern browsers. For the best experience we recommend using the latest versions of Google Chrome or Mozilla Firefox.
