    Note: The After Effects Render Queue does not support exporting to SheerVideo QuickDraw Picture (".pict", ".pct") Files or QuickTime Image (".qtif", ".qti") Files, although the After Effects QuickTime Export facility does.

  9. Check the Output Info field near the top left of the Output Module details to verify that you are using the desired Sheer codec.
  10. Compressor

  11. Ignore the Spatial Quality setting at the middle left of the Output Module details, which is always Most (100).
  12. Channels

  13. Check the Channels field at the top right of the Output Module details to verify that you are storing either RGB or RGBA, depending on whether or not you want to store an alpha channel.
  14. Channels

  15. Check the Depth field near the top right of the Output Module details to verify that you are outputting Millions of Colors (or Millions of Colors+, with alpha) for any Sheer RGB[A] 8bf codec, and Trillions of Colors (or Trillions of Colors+, with alpha) for any Sheer RGB[A] 10bf or Sheer Y'CbCr[A] codec.
  16. Precision

  17. If you are outputting an alpha channel, check the Color field near the top right of the Output Module details to verify whether the RGB channels are Straight (unmatted) or Premultiplied (matted) by the alpha channel.
  18. Precision

  19. To change any of these Output Module settings,

    1. Create a customized copy of the Output Module Template by one of the following methods:

      • Output Module Template Name Click the Output Module Template Name in the Output Module field
      • Custom Output Module Template Select Custom... from the Pop-Up Menu in the Output Module field

      to bring up the Output Module Settings dialog box.

      Output Module Settings Dialog

    2. Channels Pop-Up Menu To change which channels are stored, select the desired set of channels from the Channels pop-up menu at the top right of the Video Output section of the Output Module Settings dialog box:

      • RGB RGB, to store just the (red, green, blue) color channels, without alpha, if you don't need to preserve the alpha channel.
      • RGB + Alpha RGB + Alpha, to store the color channels with alpha (red, green, blue, alpha), if you need to retain the alpha channel.

      Note that SheerVideo does not yet include a codec for alpha only.

    3. Depth Pop-Up Menu To change the precision of the output to the encoder, select the desired precision from the Depth pop-up menu near the top right of the Video Output section of the Output Module Settings dialog box:

      • Millions of Colors Millions of Colors (or Millions of Colors+, if you're including alpha), to output 8 bits per channel to the Sheer encoder. This is the setting you should use for the Sheer RGB[A] 8bf codec.
      • Trillions of Colors Trillions of Colors (or Trillions of Colors+, if you're including alpha), to output 16 bits per channel to the Sheer encoder. This is the setting you should use for the Sheer RGB[A] 10bf codec and for any Sheer Y'CbCr[A] codec.

      Note: SheerVideo does not yet provide a Sheer RGB[A] 16bf codec. The Sheer RGB[A] 10bf codec preserves only 10 bits of information per channel. If you need to retain the full 16 bits per channel, output to 'b64a' or 'L64A' (RGBA 16b) or 'b48r' (RGB 16b). The Sheer Y'CbCr[A] 10b codecs also store only 10 bits per channel, but need to get 12 bits per RGB channel from After Effects for lossless throughput with Synchromy. Similarly, the Sheer Y'CbCr[A] 8b codecs store only 8 bits per channel, but need to get 9 bits per RGB channel from After Effects for lossless throughput with Synchromy. See the Final Workflows page for a discussion.

    4. Color Pop-Up Menu To change the color interpretation of the output images, select the desired color interpretation from the Color pop-up menu on the right side of the Video Output section of the Output Module Settings dialog box:

      • Straight (unmatted) Straight (unmatted) to output the RGB channels with premultiplying them by the alpha channel. Use this setting if you need to be able to use the output content without the matte imposed by the alpha channel.
      • Straight (unmatted) Premultiplied (matted) to output the RGB channels after premultiplying them by the alpha channel. Use this setting if you will only need to use the output content with the matte imposed by the alpha channel, and still need the alpha channel for further compositing work or other purposes.

      Note, if you only need the matted content, and you don't need the alpha for any further purposes, you should omit the alpha channel to save space and processing time.

    5. OK Click the OK button at the bottom right of the Output Module Settings dialog box to confirm the changes and dismiss the Output Module Settings dialog box. Your rendering job will now use the changed settings, and the output module settings for the rendering job will now be listed as being "Based on" the original Sheer template.

    to bring up the Output Module Settings dialog box.

    Output Module Settings Dialog

  6. Format Options... Click the button at the top left of the Video Output section of the Output Module Settings dialog box
  7. to bring up the Compression Settings dialog box.

    Compression Settings Dialog

  8. Compression type Select the desired Sheer codec in the Compression type pop-up menu at the top of the Compression Settings dialog box:
    • Sheer Sheer, to let SheerVideo automatically choose the appropriate Sheer pixel type according to the video pixel format that it receives from the After Effects Render Queue, which is always either RGB[A] 8bf if the output percision is set to Millions of Colors(+), and always RGB[A] 10bf if the output precision is set to Trillions of Colors(+).

      Thus, in this context, selecting the generic Sheer codec is equivalent to to selecting the specific Sheer RGB[A] 8bf codec for Millions of Colors(+), and equivalent to selecting the specific Sheer RGB[A] 10bf codec for Trillions of Colors(+). (See the descriptions of those codecs below.)

    • Sheer RGB[A] 8bf Sheer RGB[A] 8bf, for use in standard-precision working compositions and for transport to applications dealing in standard-precision scanned film and computer-generated imagery.

      details

      In 8-bit-per-channel Projects, this codec perfectly encodes all RGB[A] 8bf output in real time from After Effects' Rendering Queue facility, including all untouched RGB[A] 8bf source footage, with an average compression power of 2.2, so that the Sheer RGB[A] 8bf files take up only 45% as much space as uncompressed RGB[A] 8bf files, with zero loss of information.

      This codec also perfectly decodes all Sheer RGB[A] 8bf footage in real time for After Effects renderings.

      For transport to other applications, Sheer RGB[A] 8bf both encodes and decodes losslessly in real time from and to all RGB[A] 8bf pixel formats (ARGB, and, on PC+Windows, ABGR, RGBA, BGRA, RGB, and BGR), making it ideal for editing in those formats.

      For faster but lower-quality display, the Sheer RGB[A] 8bf codec can also decode in real time to RGB 5b pixel formats (B555, and, on PC+Windows, L555 and L565).

      This codec also losslessly decodes to RGB[A] >8bf pixel formats ('b64a', 'L64A', 'b48r', 'R10k', and 'r210'); and, using Synchromy, losslessly decodes to Y'CbCr[A] ≥10b 4:4:4[:4] pixel formats ('r4fl', 'V416', and 'v410').

      In addition, Sheer RGB[A] 8bf uses Synchromy to decode with the minimal loss theoretically possible to Y'CbCr[A] <10b pixel formats ('v408', 'VUYA', 'r408', 'v210', 'v216', 'Y216', '2vuy', '2Vuy', and 'yuvs').


    • Sheer RGB[A] 10bf Sheer RGB[A] 10bf, for use in high-precision working compositions and for transport to applications dealing in high-precision scanned film and computer-generated imagery.

      details

      In 16-bit-per-channel Projects, this codec perfectly encodes all RGB[A] 16bf output in real time from After Effects Pro's Rendering Queue facility to a precision of 10 bits per channel, including all untouched RGB[A] 10bf source footage, with an average compression power of 2.0, so that the Sheer RGB[A] 10bf files take up only 50% as much space as uncompressed RGB[A] 10bf files, with zero loss of information.

      This codec also perfectly decodes all Sheer RGB[A] 10bf footage in real time for After Effects Pro renderings.

      Like standard Cineon and DPX files, Sheer RGB[A] 10bf only stores 10 bits per channel. If you need to retain the full 16 bits per channel output by 16-bit projects in After Effects Professional, use the uncompressed 'b64a', 'L64A', or 'b48r' pixel format instead.

      For transport to other applications, Sheer RGB[A] 10bf both encodes and decodes losslessly in real time from and to all RGB[A] 10bf pixel formats (10-bit 'b64a' and 'L64A', 10-bit 'b48r', 'R10k', and 'r210') making it ideal for editing in RGB[A] 10bf formats.

      For faster but lower-quality display, Sheer RGB[A] 10bf can decode in real time all RGB[A] 8bf pixel formats (ARGB, and, on PC+Windows, ABGR, RGBA, BGRA, RGB, and BGR), as well as RGB 5b pixel formats (B555, and, on PC+Windows, L555 and L565).

      Using Synchromy, this codec also losslessly decodes to Y'CbCr[A] ≥12b 4:4:4[:4] pixel formats ('r4fl'), and, for RGB[A] 8bf source footage, to Y'CbCr[A] ≥10b 4:4:4[:4] pixel formats ('r4fl', 'V416', 'v410').

      In addition, Sheer RGB[A] 10bf uses Synchromy to decode with the minimal loss theoretically possible to Y'CbCr[A] <12b pixel formats ('v408', 'VUYA', 'r408', 'v210', 'v216', 'Y216', '2vuy', '2Vuy', and 'yuvs').


    • Sheer Y'CbCr[A] 8bv 4:4:4[:4] Sheer Y'CbCr[A] 8bv 4:4:4[:4], for transport to applications for compositing standard-precision digitized video.

      details

      In 16-bit-per-channel Projects, this codec losslessly encodes all untouched Sheer Y'CbCr[A] 8bv 4:4:4[:4] source footage through After Effects Pro's Rendering Queue facility, with an average compression power of 2.84, so that the Sheer Y'CbCr[A] 8bv 4:4:4[:4] input and output files take up only 35% as much space as uncompressed Y'CbCr[A] 8bv 4:4:4[:4] files. Thanks to Synchromy, this process is perfectly lossless (except for out-of-range colors) even though the pixels have to be converted to RGB[A] 16bf and back for After Effects Professional.

      Otherwise, this codec lossily encodes all RGB[A] 8bf or RGB[A] 16bf output from After Effects' Rendering Queue facility, with an average compression power of 2.84, so that the Sheer Y'CbCr[A] 8bv 4:4:4[:4] files take up only 35% as much space as uncompressed RGB[A] 8bf files, using Synchromy technology to ensure the minimal loss theoretically possible.

      For transport to other applications, Sheer Y'CbCr[A] 8bv 4:4:4[:4] both encodes and decodes losslessly in real time from and to all Y'CbCr[A] 8bu|v 4:4:4[:4] pixel formats ('v408', 'VUYA' and 'r408'), making it ideal for editing in those formats.

      For faster but lower-quality display, the Sheer Y'CbCr[A] 8bv 4:4:4[:4] codec can also decode in real time to Y'CbCr[A] 8bv 4:2:2[:4] pixel formats ('2vuy', '2Vuy', and 'yuvs').

      This codec also losslessly decodes to Y'CbCr[A] >8b 4:4:4[:4] pixel formats ('r4fl', 'V416', and 'v410'); and, thanks to Synchromy, to RGB[A] ≥9bf pixel formats ('b64a', 'L64A', 'R10k', and 'r210').

      In addition, Sheer Y'CbCr[A] 8bv 4:4:4[:4] uses Synchromy to decode with the minimal loss theoretically possible to RGB[A] <10bf pixel formats (ARGB) and to Y'CbCr[A] 4:2:2[:4] pixel formats ('v210', 'v216', 'Y216', '2vuy', '2Vuy', and 'yuvs').

      details

      This codec perfectly encodes all RGB[A] 8bf output from the After Effects Rendering Queue facility, including untouched RGB[A] 8bf source footage, with an average compression power of 1.72, so that the Sheer Y'CbCr[A] 10bv 4:4:4[:4] files take up only 58% as much space as uncompressed RGB[A] 8bf files, using Synchromy technology to ensure zero loss of information.

      In 16-bit-per-channel Projects, this codec losslessly encodes all untouched Sheer Y'CbCr[A] 10bv 4:4:4[:4] source footage through After Effects Pro's Rendering Queue facility, with an average compression power of 2.58, so that the Sheer Y'CbCr[A] 10bv 4:4:4[:4] input and output files take up only 39% as much space as uncompressed Y'CbCr[A] 10bv 4:4:4[:4] files. Thanks to Synchromy, this process is perfectly lossless (except for out-of-range colors) even though the pixels have to be converted to RGB[A] 16bf and back for After Effects Professional.

      For transport to other applications, Sheer Y'CbCr[A] 10bv 4:4:4[:4] both encodes and decodes losslessly in real time from and to all Y'CbCr[A] 10bv 4:4:4[:4] pixel formats (10-bit 'r4fl', 10-bit 'V416', and 'v410'), making it ideal for editing in those formats.

      For faster but lower-quality display, the Sheer Y'CbCr[A] 10bv 4:4:4[:4] codec can also decode in real time to Y'CbCr[A] 8bu|v 4:4:4[:4] pixel formats ('v408', 'VUYA', and 'r408'), to Y'CbCr[A] 10bv 4:2:2[:4] pixel formats ('v210', 'v216', and 'Y216'), and to Y'CbCr[A] 8bv 4:2:2[:4] pixel formats ('2vuy', '2Vuy', and 'yuvs').

      This codec also losslessly decodes to RGB[A] ≥12bf pixel formats ('b64a', and 'L64A') using Synchromy.

      In addition, Sheer Y'CbCr[A] 10bv 4:4:4[:4] uses Synchromy to decode with the minimal loss theoretically possible to RGB[A] <12bf pixel formats ('R10k', 'r210', and ARGB).


    • Sheer Y'CbCr[A] 8bv 4:2:2[:4] Sheer Y'CbCr[A] 8bv 4:2:2[:4], for transport to cutting and archiving standard-precision digitized video.

      details

      This codec lossily encodes all RGB[A] 8bf and RGB[A] 16bf output from After Effects' Rendering Queue facility, with an average compression power of 3.64, so that the Sheer Y'CbCr[A] 8bv 4:2:2[:4] files take up only 27% as much space as uncompressed RGB[A] 8bf files, using Synchromy color conversion to ensure the minimal loss theoretically possible.

    • Sheer Y'CbCr[A] 10bv 4:2:2[:4] Sheer Y'CbCr[A] 10bv 4:2:2[:4], for transport to cutting and archiving high-precision digitized video.

      details

      This codec lossily encodes all RGB[A] 8bf and RGB[A] 16bf output from After Effects' Rendering Queue facility, with an average compression power of 2.36, so that the Sheer Y'CbCr[A] 10bv 4:2:2[:4] files take up only 42% as much space as uncompressed RGB[A] 8bf files, using Synchromy color conversion to ensure the minimal loss theoretically possible.

      For transport to other applications, Sheer Y'CbCr[A] 10bv 4:2:2[:4] both encodes and decodes losslessly in real time from and to all Y'CbCr[A] 10bv 4:2:2[:4] pixel formats ('v210', 10-bit 'v216', and 10-bit 'Y216'), making it ideal for processing in those formats.

    8b stands for 8 bits of information per color channel, the standard precision of digital displays.

    10b stands for 10 bits of information per color channel, the standard precision of digitized film and computer-generated imagery.

    u stands for unbiassed video-range, with headroom for filter overshoot but no footroom for undershoot, otherwise per ITU-R BT.601-4.

    v stands for video-range, with foot- and headroom for filter under- and overshoot, per ITU-R BT.601-4.

  10. to bring up the Sheer Settings dialog box.

    Sheer Settings Dialog

  11. Specify whether or not you want to turn on SheerVideo's self-check mode to verify each compressed video frame by decompressing it to the input pixel format (which is always RGB[A] 8bf for 8-bit After Effects Projects, and always RGB[A] 16bf for After Effects Professional Projects) and comparing the restored frame to the input, by clicking on one of the following radio buttons at the top of the Algorithms section of the Sheer Settings dialog box:

    • One-way (faster) One-way (faster), to have SheerVideo just encode the video. This is the default value.
    • Self-check (safer) Self-check (safer), to have SheerVideo encode, decode, and compare the result, to verify that each frame is encoded with perfect fidelity.

      Self-check mode must be turned off to allow destructive conversion. You should only use self-check mode when no pixel-format conversion is required (for rendering from After Effects 8-bit-per-channel projects to Sheer RGB[A] 8bf, or for rendering untouched RGB[A] 10bf source footage to Sheer RGB[A] 10bf), or when perfect pixel-format conversion is possible (for rendering from After Effects 8-bit-per-channel projects to Sheer RGB[A] 10bf or Sheer Y'CbCr 10bv 4:4:4[:4]).

      Do not use self-check mode for rendering from After Effects to Sheer Y'CbCr[A] 8bv 4:4:4[:4], Sheer Y'CbCr[A] 8bv 4:2:2[:4], or Sheer Y'CbCr[A] 10bv 4:2:2[:4]. Even with Synchromy technology, the RGB[A] 8bf output from After Effects Pro's QuickTime Export facility cannot be perfectly converted to any Y'CbCr[A] formats of precision less than 10 bits or to 4:2:2[:4] chroma-subsampled images.

    Unfortunately, QuickTime provides no way for the encoder to determine the source format, so SheerVideo does not have the information it would need to disable this choice when it is inapplicable.

    Note that SheerVideo is so fast compared to other system bottlenecks that you may not notice any slowdown in using the self-check mode, especially for frames small enough to fit in the CPU cache.

  12. Specify whether or not you want to take advantage of any vector processor in your computer by clicking on one of the following radio buttons at the bottom of the Algorithms section of the Sheer Settings dialog box:

    • Scalar Scalar (energy saver), to have SheerVideo execute a scalar code version of the codec, to save battery power on a laptop with a vector processor, such as a PowerBook G4.
    • Vectorized Vectorized (faster), to have SheerVideo execute a vectorized code version of the codec. When available, this is the default value.

    Many of SheerVideo's codecs are available in two forms: scalar code, to run on a scalar processor; and vectorized code, to run on a vector processor. The vectorized code speeds up encoding and decoding by nearly a factor of two, but increases energy consumption, which can be an important consideration on battery-powered computers. Moreover, since vector processors are much more complicated and vectorized algorithms are much more complicated, switching to a scalar algorithm can be diagnostically useful.

  13. Select which coding method you want SheerVideo to use, by clicking on one of the following radio buttons in the Coding section of the Sheer Settings dialog box:

    • Progressive Progressive, if you want to encode the frame in progressive-scan mode. Progressive coding usually compresses better for content having little or no interfield motion.
    • Interlaced Interlaced, if you want to encode the even and odd fields of the frame independently. Interlaced coding usually compresses better for content having large interfield motion, and is often slightly faster.
    • Automatic Automatic, if you want the coding method to be determined by the images' Field Info image description extension. This is the default value. Note, however, that as of QuickTime 7.0, there is still no mechanism for QuickTime encoders to access the image description extensions of the source.
  14. Select whether or not to have the Sheer encoder accept only pixel formats that can be encoded perfectly, by clicking on one of the following radio buttons in the Pixel Format Conversion section of the Sheer Settings dialog box:

    • Perfect Perfect, to accept only pixel formats that permit perfect encoding. Do not use this for rendering from After Effects to Sheer Y'CbCr[A] 8bv 4:4:4[:4], Sheer Y'CbCr[A] 8bv 4:2:2[:4], or Sheer Y'CbCr[A] 10bv 4:2:2[:4], since converting to any of these formats from the RGB[A] 8bf or RGB[A] 16bf pixel format provided by the After Effects renderer is inherently destructive, even with Synchromy, because of precision reduction or chroma subsampling. Likewise, do not use this for rendering from any 16-bit-per-channel project in After Effects Professional, because of inherent precision reduction.
    • Best Best, to encode using the best possible method even if the pixel format cannot be converted without information loss. This is the default.
