Video Slave 3 - Using Video Slave as standalone video player

 

While Video Slave was primarily designed as a synchronized video player, it is also well suited to be used as a standalone playback solution. As with every standalone video player, Video Slave's playlists can be used as a collection of media that should be played in order. To define the order in which the movies occur, please adjust the start timecodes accordingly.

It is currently not possible to modify the order by dragging-and-dropping the movies around in the playlist. This might be added in a future update.

Using the playlist, you can playback a movie consisting of several files without stopping between reels. Video Slave will just play the next movie if one movie is at the end. As this behavior might be unwanted when using Video Slave in sync to an audio software, you can toggle the playback behavior in Video Slave's general preferences:

Toggle the "Load the next clip in the playlist when the current clip is at the end" checkbox to get your desired behavior.

 

Using In and Out Points

Playing back several movies in a row can be problematic if the movies have test tones and beeps before and/or after the actual content for example. To get around this, Video Slave 3 lets you define an in and out point per movie. To set them, go to your desired frame, then click the Transport menu and select "Set Clip In Point to Current Frame" or "Set Clip Out Point to Current Frame". You will see a line with a dot left or right to it appear in the timeline view:

 

 

If the line and dot are drawn gray as in the image above, Video Slave will not respect them. To toggle in/out points on or off globally, we added a button in the transport bar:

 

 

When In/Out Points are enabled (if the button shows a blue icon), the In/Out Points in the timeline view will change to a green-ish color:

 

 

With In/Out Points enabled, you can still locate to frames outside the In/Out range, but you only play between the In and the Out Point.

Fading to and from black

Additionally, Video Slave offers the possibility to fade from and to black on In/Out Points respectively. To set the number of frames used to fade in or out, open the general preferences, enter your desired values and hit enter.

 

 

Switching resolution and frame rate of external video devices automatically

When using Blackmagic and AJA devices, it is up to you to choose the frame rate and resolution at which these devices playback. Video Slave will do its best to playback all movies with all output settings you choose, it might however lead to a quality degradation if e.g. the movie's frame rate and the display frame rate of the device don't match. Video Slave will only do a very basic frame rate conversion that might not be sufficient for high quality playback requirements.

In all cases, it is optimal if the frame rate and resolutoin of the movie match that of the output device. This way, no conversion needs to take place and the quality is kept as high as possible.

Thus, Video Slave now has a new handy feature which lets it match the output settings of the output device to that of the movie automatically. Whenever you switch movies, Video Slave will update the output device's output frame rate and resolution automatically. Still, you can choose if you want Video Slave to match the settings for you or if you prefer to choose a setting yourself. Open the application's preferences and switch to the "Display" tab, select the external device you want to modify the setting for and toggle the checkbox shown below:
