 . Insert your tape in the appropriate machine and hit play\\
 . Adjust the sound levels on the Sescom audio converter.  If you want to try and adjust the video, make adjustments on the Time Base Corrector (the thing with the flashing lights), otherwise you can just leave it on automatic.\\
-. Select Video Settings on the Capture drop down to select your compression type.  H.264-Best is good for a preservation master. {{:aja_vtr_capture_window.png?200|}}\\
+. In AJA Control Room, open Preferences and select the location you would like to save your clips (AKA the "capture path"). Recommended practice is to save to G-RAID external drive folder "AJA Capture" as a holding location before you make access versions and move them to appropriate final location.{{:save_location.png?200|}}\\
-. Name your file\\
+. Select the Capture tab in Control Room and click on File Type to select the file format. For an archival master Apple Pro Res 422 (HQ) is the best of these options.{{:capture_screen.png?400|}}\\
-. Hit Capture Now on the VTR Exchange then play on the deck.\\
+. Name your file in the File Name field.\\
-. Hit stop on the VTR Exchange when the tape ends and the file will be saved on the G-RAID drive.\\
+. Press the red square record button located in the far right side of the screen, then hit play on your source deck to begin capturing.\\
-. Make a lower-res access copy in Adobe Media Encoder.  We use the h.264 mp4 encoding. {{:adobe_encoder.png?100|}}\\
+. Hit the red record button again to stop capture. The file will be saved wherever you indicated in step 6.\\
+. You can use Adobe Media Encoder to make a lower-res access copy.  We use the h.264 mp4 encoding but there are TONS of options. {{:adobe_encoder.png?100|}}\\
+You can also use Adobe Premiere to capture footage. The instructions are below in the PAL section.

 . Select File--->Export--->Media.\\
 . Select the file format you want for your file.  Adobe sez "Select the preset best suited for your target means of playback".  In our case we would create an "Archive Original" and an "Access" copy so that means exporting twice.  This could be easier if you sent them both to Queue.\\

+===== Notes about future digitization of film =====
+"We digitize dozens of formats of video, film, and audio in our studio and have a few suggestions:
+. DPX is fine, but vary large and not very accessible. Unless you're planning on frame-by-frame restoration I might suggest something smaller like an MXF file with ProRes 444 encoding.
+. For access I'd also suggest an MP4 file with high-quality H.264 encoding.
+. Make sure the film is cleaned before digitization.
+. You can request a 4k capture, but I think it's overkill and beyond the point of diminishing returns. A 4k capture of Standard/Regular 8 film yields about 22,000 PPI, which is way beyond what is on that film. We offer 2k+ which still captures a high-definition frame-by-frame digital file.
+. The biggest practical decision might be about aspect ratio and crop. For example, are you okay with a 4:3 aspect ratio, which is the aspect ratio of the film or do you want a 16:9 file with letterboxing (black bars on sides)? And do you want to capture just the image area of the film, or are you interested in the entire width go the film including film markings and sprocket holes?
+. If you get a good frame-by-frame capture you shouldn't need any stabilization.
+. After the film is digitized you can review the footage and decide if it needs any colorization. You can always keep the original capture and create an alternate file that is more faithful to the original. Some films will suffer from fading that render the image very magenta or red but can be recovered digitally with color correction software."
