Abstract: One or more techniques and/or systems are provided for video stabilization and/or for image frame generation. For example, a user may instruct a video application hosted on a smart phone to capture a video at a target resolution of 1080 pixels. A padded input having a padded resolution that is larger than the target resolution may be obtained from a capture device, such as a camera of the smart phone. The padded input may be provided to a video stabilization component to obtain a target image frame having the target resolution. In this way, the video stabilization component may perform cropping using padded margin pixels (e.g., additional pixels of the padded input beyond the 1080 pixels of the target resolution) so that image upscaling after cropping (e.g., to account for global warping, etc.) may be mitigated to reduce blur that may otherwise result from image upscaling.

Abstract: A remedially deployable subsurface valve assembly is provided including a first tubing string, a first safety valve positioned in the first tubing string, a second tubing string, and a second safety valve positioned in the second tubing string. The first tubing string is a rigid production tubing string deployed in a hydrocarbon production wellbore extending beneath an earthen surface. The second tubing string is a flexible coiled tubing string remedially deployed in the interior of the first tubing string when the first safety valve fails. The second safety valve, which is located at the end of the second tubing string, is nested within the first safety valve to render the first safety valve inoperably fixed in the opened position. A seal, which is positioned in the annulus formed between the first and second tubing strings, defines a pressurizable segment of the annulus in pressure communication with the second safety valve.
