These are sequential image frames stored on a fast, hard disk. Supported playback file types include; 7TH (STH), TGA, YUV, A7S, DPX, DPX 2.0HDR, OpenEXR SDR and HDR, CIN, SGI.
Codec filetypes (MXF, MOV, MP4, LXF, ASF, WMV, DV, MPEG-PS, MPEG-TS, GXF, FLV, AVI, MKV, WebM, HapQ, 7thHapQS) are supported.
Codecs Note: codecs are supported for media prototyping type purposes only, and are never recommended as the final deliverable/show content. With codec movie formats, the audio is in-built and speaker mapping is encoded in the file itself, so Delta audio control available is therefore only volume control (no channel mapping as is possible with separate audio files – see audio files below). Since codec playback in Delta is CPU-based, this typically allows only 1-2 movies at HD 60p or equivalent resolutions. For anything more, codec movies should be converted to image sequences using Distributed File Manager. NotchLC This is a Luma & Chroma (YUV) codec that uses LZ4 to achieve compression rates between 5:1 and 8:1 with minimal perceived quality loss, and is suitable for very large canvases. From Delta 2.8, NotchLC codec in .mov wrappers can be played, but note that audio is not enabled in this format. If exporting from Adobe Media Encoder, first deselect ‘Export Audio’. Used in its .mov wrapper, NotchLC is CPU intensive and takes longer to process each frame. To avoid this, whilst retaining the NotchLC format, use the ‘NotchLCTo7th.exe’ utility installed with Delta 2.8.7 on. ➢See: MC256 Managing Media for Delta, NotchLC to NotchLC7th utility. |
Supported file types for recording (also known as carving or slicing) are JPG, JPEG2000, BMP, TIF and PNG, in addition to all movie formats listed above.
Individual movies are stored in separate folders under the MOVIES folder like this:
Note that the movie name presented in the DeltaGUI is the name of the First file found, minus the frame count (e.g. Movie1_0001, Movie1_0002.tga, Movie1_0003 will be shown as ‘Movie1_’ in the resources area (note the underscore).
Movie thumbnails
By default, DeltaServer creates a thumbnail of the first frame of every movie whenever the Resource Pool is refreshed, and stores these in C:\7thSense\web\data\thumbnails. Thumbnails are used as resource pool icons and on the timeline to help identify assets.
Movie files beginning other than frame numbered ~00 will show a thumbnail of the first frame found, and display the number of the first frame, in the file Information shown on timeline resource hover, and dialogs where a Start Frame is set. (A feature added with Delta 2.7.)
Example: Movie starts with frame ‘name_0140.tga’. Thumbnail of frame 140 is shown and in dialogs, this additional information:
Note: ‘Start Frame 00’ becomes relative, so to stop at stop frame of 50 would mean frame filename ending ‘name_0190.tga’.
Notes on Movie File Sequences
•The movie filenames require a fixed number of digits for the framecount, preceded by an underscore, so:
Movie_0998, Movie_0999, Movie_1000 is acceptable
Movie_998, Movie_999, Movie_1000 is not suitable.
•For best playback performance of uncompressed media, use TGA, DPX sequences or convert image sequences to one of the 7TH file format using the supplied DFM utility.
•Best performance is achieved when the Movies are served from one drive or RAID set, and all other content is served from a separate drive.
Configure this in Preferences > Disk Drives in the DeltaGUI.
•TGA, SGI, CINeon, DPX or YUV single file per frame format require Solid State drives (SSD) to play these movies in realtime.
•TGA single file per frame movies can also have an alpha plane – this will require fast disks. Uncompressed or RLE compressed TGA files only
•DPX: .dpx formats are broadly supported:
o8-bit (4:4:4)
o10-bit (YUV and 4:4:4)
o12-bit (4:4:4)
ofull support of little- and big-endian
ofilled and packed types are both supported
o8-bit RGBA
o10-bit RGBA
oV2.0HDR is supported from Delta 2.7 build 7.
