Process Your Takes
Now that you're at the stage of creating a Take - it's time to extract some motion!
- Click the '+ Take' icon and select the videos from each camera angle of your desired action take.
You can stop at any time to preview the videos you are selecting, selected videos will be hgihlighted in green.
- To help you fill out the information, we’ve added details below.
- Scene: Create a New Scene or select the Scene in which you wish to add your take.
- Title: Give your Take a Title.
- Actor Number: You must tell the system how many people are in the take, as this ensures it tracks all Actors.
- Prop: Here you can select if you have any props in the scene you would like to track. Currently the platform only supports the tracking of a single football.
- Time sync clapping Start/End: Input the clap times if using an asynchronous system, this should be as accurate as possible to ensure an accurate sync. If the videos are already synced manually or from your camera type then untick the 'Autosync Videos' box.
- Time take action starts: This is the start time of the action in your take. Always start your take when thr Actor/s in the video are clearly visible and not occluding each other.
- Time take action ends: This is the end time of the action in your take, or when you want your animation output data to finish.
A video preview window will now show from the selected camera angle for you to select your Actor. You can skip this step if an Actor Profile does not exisit for the Actor in the Take.
- Select the camera angle that has the clearest view of the Actor/s in the Take.
- Left click and drag a bounding box around the Actor in the video. If using multiple Actor Profiles, ensure boudning boxes do not overlap as this will confuse the system.
- When you draw your bounding box on the video, this will show in red. Once finished, match the Actor from the list of profiles below in the 'Actor Selections' box.
- Nexk, click 'Next Create Run.
- Select the calibration you want to use. This should be for the same camera positions as the Take you are about to process
- Fingers: ON or OFF. Finger tracking will increase processing time.
- Rigs: Select the Rig you want to retarget to.
- Click 'Run' and your video will now start processing.
Note: An email notification will be sent out to the user who created the Take, so there is no need to keep the platform tab open while the processing is taking place.
The process duration will be dependent on a combination of factors and therefore at the time of this publication we cannot provide an accurate estimate. These factors include, but are not limited to number of actors, duration of clip, number of cameras, amount of motion etc.
When using GoPro Hero8 or Hero9 cameras, the aim platform requires performers to clap at the beginning of a calibration or a take. The aim platform looks for the audio peak from the clap and automatically synchronises all clips for that calibration or take. The aim platform prompts you to set a Clap Start Time and a Clap End Time. Setting this time range i.e. from 00:01 to 00:04 in your Calibration or Take helps narrow down the system’s automatic search window.
The aim platform allows you to specify the time range of the take that you wish to extract motion for. I.e. if you have a clip that is 2 minutes (timecode: 02:00) long but you only wish to extract motion for a sub-range such as 00:05-01:10 then you can specify this in the aim UI.
It is best practice to clap at the beginning of any Calibration or Take performance that is undertaken. This allows you to easily search for the Start/End times for both the clap and/or the Calibration/Take.
When you get to your Take Overview you have a number of options available to you.
When you run a take, it will trigger the extraction process. Before running, you have a couple of options:
- Calibration. If you have recorded multiple calibrations, you can select the one you wish to use for your Take
- Rig: aim allows you to automatically retarget your motion capture data onto any rig of your choice. To select the rig you want, simply choose it in the dropdown. For instructions as to how to set up a rig in aim, take a look at this page
When you're happy with your choices, press 'Run' - aim will do the rest of the work for you.
