What SDI cards are compatible with Baselight STUDENT?
How can I get the material used for the example tutorials in the User Guide?
I inserted the Baselight tutorial shots into my timeline using the Sequence Browser but the display shows a grey ‘X’.
Why can’t I play back audio files in the Sequence Browser?
In the tutorials, the strips in the timeline are brightly coloured and solid. Why do mine look different?
When I quit Baselight I get a message saying Multi-Paste preferences have changed, but I didn’t change them.
As Baselight STUDENT is specifically intended to help people learn how to work with Baselight professionally, the licence is limited to a 90-day training period; however, we understand that sometimes other commitments get in the way, so this can be reviewed if necessary when your licence expires.
Contact us at [email protected] when your licence expires. We cannot extend licences that are still current.
We’re currently working on a series of tutorials specifically for Baselight STUDENT. In the meantime, many of the tutorials we’ve developed for Baselight and Baselight Editions are just as relevant for Baselight STUDENT. You can find them here:
You can also access the Baselight user documentation from the Help menu or on our web site:
Not yet. FilmLight is developing an accredited course centred around colour grading with Baselight. Feel free to contact us at [email protected] and we’ll get back in touch with you as soon as a training curriculum is available.
As an academic you are, of course, welcome to register for a licence yourself to evaluate the suitability of Baselight STUDENT for your prospective course.

See the instructions below for information about how to update your Postgres server.
If you receive a warning or error that mentions database connection problems, or other database errors such as Baselight cannot access the database or is unable to contact the global formats database host, reboot your Mac and then run the following command in a terminal.
The terminal can be accessed from the Applications > Utilities folder on most Macs. Note that it is important that you run this command straight after rebooting – do not try to run Baselight or any other applications first or the command may fail:
After running this command, reboot the Mac again.
If you have already tried the previous solution for Database problems and still receive an error regarding database connection problems, this may be because the Postgres database access permissions have previously been configured for use by the Resolve installer.
First of all, make sure that you are using the latest version of Baselight STUDENT. You can check what version you are running by going to Baselight > About Baselight on the main menu. Then visit Baselight STUDENT Downloads and download a new version if you need to.
If updating doesn’t fix the problem, luckily we can modify the database permissions to allow Postgres to work with both Baselight and Resolve:
- Open Terminal and edit the following file by typing:
sudo nano /Library/PostgreSQL/<Postgres version number>/data/pg_hba.conf <Enter>For example:
sudo nano /Library/PostgreSQL/9.3.4/data/pg_hba.conf <Enter>
- At the end of the file (in the actual configuration section), change the Method at the end of each line to trust (it probably reads MD5 before editing). After editing and saving the file, it should look something like this:
- Exit Terminal and then reboot your Mac so that the Postgres server is restarted.
|# "local" is for Unix domain socket connections only|
|# IPv4 local connections: host||all||all||127.0.0.1/32||trust|
|# IPv6 local connections: host||all||all||::1/128||trust|
Both Baselight and Resolve should then happily run on the same Postgres database server.
To fix this:
- Open Terminal and change to the root user:
su - <Enter>
- Now edit the /etc/hosts file with your preferred text editor. For example, type:
nano /etc/hosts <Enter>
- Add the following lines and then save the file:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
There is a known issue with using AJA Thunderbolt devices (such at the T-TAP) via a USB-C to Thunderbolt convertor. This configuration is currently unsupported.
You can still run Baselight STUDENT without SDI monitoring:
- Run the bl-setups utility (in the Applications > Baselight STUDENT folder).
- Click the Show Editor button.
- On the Display tab, set the Primary Video Output to No output and click Save.
This is the default location that Baselight uses for images and movie files. You can specify a different location using bl-setups.
- Run the bl-setups utility (in the Applications > Baselight STUDENT folder).
- Click the Show Editor button.
- Scroll to the bottom of the New Scenes tab to the Image Containers & Proxies section.
- Change the Default container directory and click Save.
Note that you can also change the default container for an individual scene in the Scene Settings window.
There may be several reasons why playback is not smooth - please check the following:
- On the Baselight main menu, select Baselight > Preferences. On the System tab, check the Baselight on-disk cache location is set to a folder on a drive that is fast enough to play back uncompressed HD video in real time (see below for a method for checking if your cache drive is fast enough).
The folder must have read/write permissions for the current user. If the background of this field is shaded red then Baselight will not be able to use a disk cache when playing back.
- Still on the System tab in the Preferences, check also that Enable Background Caching and Show Caching Status In Timeline are both enabled. Save and exit the Preferences.
- On the Baselight main menu, select Views > Open Scene Settings. On the General tab, check that Timeline Caching is set to Full.
- In the UI, check that the Viewing Format in the Cursors panel is set to HD 1920x1080 or lower (this determines the size of frames used for the cache).
- Before pressing play, make sure that there is a solid green line along the top of the timeline - if the background caching process is still running you will see a green spinner. You can still play back but frames that have not yet been cached may not play back smoothly.
Note that a purple line along the top of the timeline indicates that Baselight will not cache those frames as they are ungraded and can be played out directly from the source media. However, some compressed formats may not decode in real time on some Macs; in this case you simply need to add a ’dummy‘ layer to the shot by inserting a layer but not changing any of the controls. If you do this, you should see a green cache indicator line start to grow along the top of the timeline in place of the purple one.
- If everything you have checked up to this point seems OK but playback is still not smooth or runs slow, then check the connection to your display - make sure that its current refresh rate is at least the same as the scene’s working frame rate. Note that some 4K or UHD non-Apple displays may require special drivers or settings to ensure they work at their full refresh rate. If possible, test with a standard HD 1920x1080 display.
- If the display seems OK then check the speed of your cache disk using a third-party utility.
When the Baselight timeline is cached you will see a green line along the top. This should enable smooth playback even with complicated grades and other effects as long as your cache drive is fast enough. You can test this by doing the following:
- Create a new scene and set the working format to HD 1920x1080 and the frame rate to 24fps.
- Insert Bars from the Insert menu.
- Set the length of the bars to one minute by typing 00:01:00:00 into the Len field at the top of the parameter control panel.
- Check that your Viewing Format is set to HD 1920x1080 (this is in the Cursors panel).
- Check that you see a green line along the top of the timeline, indicating that the Bars strip has been cached.
- Press <F> on the keyboard to bring up the fps display.
- Press the <Spacebar> to start playback.
The fps indicator should show a steady frame rate (note that it may say ’cadenced‘ if the refresh rate of your monitor is different from the scene’s working frame rate and the fps reading may dither slightly, but playback should still be steady).
If the playback from cache is slow then reduce the Viewing Format to HD 1280x720 and allow the timeline to re-cache. Try playback again. If the playback is now smooth then this indicates that your cache disk is not fast enough to supply 1920x1080 frames at the working frame rate. In this case you can either choose to view (and therefore cache) at the lower resolution or you may be able to switch the cache to a location on a faster disk.
No, external GPUs in Thunderbolt enclosures are not supported.
The following AJA devices can be used with Baselight STUDENT:
- Kona 3G
- Kona 4
The tutorials in the Baselight User Guide were originally written for use with the full Baselight systems, which are supplied with the example shots already copied onto the system RAID. If you would like to use the same material when following through the tutorials on Baselight STUDENT then you can download the footage and example EDLs from here:
Note that this file is about 1.2GB in size so it may take some time to download. Once you have the .iso file, you will need to extract the contents and copy them to a suitable location on your media drive. On a Mac, you can do this simply by double-clicking the .iso file and then dragging and dropping the contents to another folder.
To keep the file size small for download, the example DPX sequences have a frame size of 640x486. This is exactly a quarter of the full 2K film frame size (2048x1556). If you use the multi-insert mode in the Sequence Browser then Baselight will try and match up the resolution to a standard frame size - in this case, it may decide that 640x486 is a low-resolution proxy of the 2048x1556 2K film format, and will automatically set these shots to a 2K format in the timeline.
To correct this, select each shot strip in the timeline. In the Sequence operator, find the Geometry section and change the Input Format to (640x486).
You can change multiple shots at once using group grading mode. Note that this problem does not occur when conforming an EDL or inserting single sequences using the Sequence Browser.
The Sequence Browser can only preview image frames so although you will be able to view the metadata in audio files, you will not be able to play them back or hear any sound from movie files containing audio.
You can change the appearance of the strips in the Baselight Preferences.
- Select Baselight > Preferences from the main menu.
- On the Timeline tab, set the Strip Appearance to Flat and click Save.
If you see this message when you quit Baselight, just click the Save button even if you haven’t made any changes to the Multi-Paste settings. You should not see this message again the next time you quit Baselight.
