Video formats and Live Video

Video Formats

All the standard video formats commonly known as container formats, such as .avi, .mov, .vob or .mpg can be used in the software. Inside these containers are media in the form of so-called codecs for video and audio. MXWENDLER can read and process all standard codecs, differentiating thereby between ‘internal’ and ‘external’ processing. In internal processing, media are transferred – aided by system codecs - into an own format specifically developed for real-time compositing with high-resolution video streams: the CPU in the computer is no longer required to unpack the converted media, and can concentrate instead on the graphics. This method enables the 5-times forwards/backwards warping controls, excellent latency at keypoints, frame blending slow motion, and the processing of image sequences. However, to do this, the video material must first be imported. For the direct processing of video material, MXWENDLER uses an FFMpeg-based decoder that can play performance-optimized video of up to 4K, and which supports multi-channel audio (also via ASIO).

Live Video

MXWENDLER supports nearly all industry-standard grabber- and live input hardware components through Quicktime and DirectShow interfaces. Grabbers for BNC, DVI and SDI video are possible. Latency can be reduced to a minimum, down to under 0,08 seconds, by overclocking the system.

Flash

MXWENDLER can read and process Adobe Flash files (.swf). These Flash media can also be interactive. In MS Windows, the file is processed by the native Flash interpreter, meaning that all formats are supported. In OS X, a performance- optimized OpenGL Flash interpreter is used, which supports Action Script up to version 1.0.

Images

All standard image formats are supported (.jpg, .png, .psd, etc.).


Open different Media

Open Avi Files

- A - Click on the first Preload. The Preload Preview opens (red box).
- B - Left-click on Open to search for the desired file.
- C - Select and open the avi / mov file.


The file is now in preload, and is ready for use.

Open a Live Video

Connect the camera to the computer; you may need to restart the software.


- A - The Live-Camera must first be activated in MXWENDLER.
Settings → Media → Live devices → Double-click ‘unknown’ → ‘known’
The camera can now be loaded into the Preload.
- B - Open the next Preload. Select the camera in the preview menu under Live Media.


The live video is now in Preload and is ready for use.

Open Flash Files

Opening a Flash file follows the same process as opening an avi file.


Open Images and Creating Image Sequences

Two things must be considered before the images can be loaded into the Preload:

The images should be stored in a separate folder, and must contain sequential numbering: e.g. Clip_001.png, Clip_002.png...


- A - Open the next Preload.
- B - Click on 'Open' to open the folder containing the images.
- C - Open the first image in the folder. Confirm with 'Yes' to import as a sequence, and set the desired compression quality.


The sequence is now in Preload and is ready for use.

Triggering the four media with the keyboard

- A - At the bottom of each Preload are four gray buttons:
Add: Creates a new layer with the clip.
Once: Plays the clip once in a new layer.
Trigger: Plays the clip in a new layer as long as the key is active.
FlipFlop: First keypress creates a new layer with the clip, second keypress removes the layer again.


The following must be completed to associate a Preload with a specific key:

- B - Grab the Action Pad on its right bottom corner and open it by dragging it down.
- C - Each Preload is assigned to a desired key by using drag&drop:
Left-click → trigger (avi file) → drag&drop → y (Keyboard)
Assign the three other medias as well to random keys.
- D - The four media can now be triggered from the keyboard.
- E - Pressing two keys at the same time triggers both assigned media, they are played back simultaneously in the output window.


In the Keyboard Event Settings definitions can be changed or deleted:

Settings → Input and Output → DMX/MIDI/Keyboard Events → Keyboard
