Video slow & fast speed Ramp for Android

It works, but the controls leave A LOT to be desired. How about allowing me to type in my desired start/end and/ or duration? The control methodology and user experience is incredibly antiquated and way below the expectations for a Android app in 2020; it's more like an app from 1998. The developer can do better. It gets the job done but that's about it.

I have checked at many places and found that this is the only application that does speed up and speed down both operations in the same video very easily. It works exactly as described. The support team is also very active and reply instanly to customer’s questions. I have recommended it to my friends also.

I am impressed by how perfectly the application accomplishes its job. I have sped up and slowed down many videos using this application. I have also sped up and sped down many sections of the same video and it has never failed me. The resulting videos are good and satisfactory. This is a value for money application.

This is quite effective, and accurate down to fractions of a second. It also saves out the changed file without bloating the file size nor messing up the video quality. I appreciate that it now keeps the audio (time compressed or extruded, as applicable, and without shifting pitch), though maybe that should be an toggleable option instead of a permanent change to the app behavior. At any rate, the developers added this (based on the mobile version having it) within about 1 day after I requested it. The only things I would improve at this point are 1) doing something to eliminate the slight stutter that happens right before the slow/speed effect (in a video in which the effect being inserted in mid-video), 2) a progress indicator for saving out the changed video, and 3) adjusting the app’s name to "Video Slow & Fast Speed Ramp"(or just "Slow & Fast", or whatever) to match standard English orthography for titles ("Video slow & fast speed Ramp" is a really weird way to write it).
