Systems and methods for efficient media editing
In the field of media editing, in one embodiment, a computer-implemented method may include steps for receiving a file at a user device, the file including a video; presenting a representation of the video at the user device; receiving a user selection indicative of a scrubbable portion of the video at a first time; generating a reversed video portion at the first time based on the scrubbable portion; receiving a scrubbing input and a playback speed at the user device, the scrubbing input indicative of playback of the scrubbable portion of the video in a forward direction and in a reverse direction; generating a scaling factor between the scrubbing input and the playback speed; scaling the reversed video portion based on the scaling factor to yield a scaled reversed video portion; and generating additional instructions to combine the video and the scaled reversed video portion to produce the media file.

presenting a representation of the video at the user device;
receiving a user selection indicative of a scrubbable portion of the video at a first time;
generating a reversed video portion at the first time based on the scrubbable portion;
receiving a scrubbing input and a playback speed at the user device, the scrubbing input indicative of playback of the scrubbable portion of the video in a forward direction and in a reverse direction;
generating a scaling factor between the scrubbing input and the playback speed;
scaling the reversed video portion based on the scaling factor to yield a scaled reversed video portion; and
generating instructions to combine the video and the scaled reversed video portion to produce the media file.
2. The system of claim 1 , wherein the instructions comprise additional instructions to combine a first portion of the video that occurs before the scrubbable portion, the scaled reversed video portion, and a second portion of the video including the scrubbable portion and a remainder of the video.
3. The system of claim 2 , wherein the instructions comprise additional instructions to compress the second portion.
4. The system of claim 1 , wherein the operations further comprise presenting a preview of the media file at the user device based on the scrubbing input.
5. The system of claim 1 , wherein the file further comprises existing audio, and the program code further comprises processing the file to filter the existing audio.
6. The system of claim 1 , wherein the operations further comprise:
receiving an audio file at the user device, wherein the audio file is selected from a database of audio files; and
generating a reversed audio portion of the audio file at the first time.
7. The system of claim 6 , wherein the operations further comprise:
scaling the reversed audio portion based on the scaling factor to yield a scaled reversed audio portion.
8. The system of claim 7 , wherein the instructions comprise additional instructions to combine the video, the scaled reversed audio portion, and the scaled reversed video portion.
9. The system of claim 1 , wherein the generating the reversed video portion at the first time based on the scrubbable portion is performed in a background process while the user is performing editing operations on the user device.
10. A non-transitory computer-readable medium storing computer-executable program code for producing a media file which, when executed by a processor, cause the processor to perform operations comprising:
receiving a file at a user device, the file including a video;
presenting a representation of the video at the user device;
receiving a user selection indicative of a scrubbable portion of the video at a first time;
generating a reversed video portion at the first time based on the scrubbable portion;
receiving a scrubbing input and a playback speed at the user device, the scrubbing input indicative of playback of the scrubbable portion of the video in a forward direction and in a reverse direction;
generating a scaling factor between the scrubbing input and the playback speed;
scaling the reversed video portion based on the scaling factor to yield a scaled reversed video portion; and
generating instructions to combine the video and the scaled reversed video portion to produce the media file.
11. The non-transitory computer-readable medium of claim 10 , wherein the instructions comprise additional instructions to combine a first portion of the video that occurs before the scrubbable portion, the scaled reversed video portion, and a second portion of the video including the scrubbable portion and a remainder of the video.
12. The non-transitory computer-readable medium of claim 11 , wherein the instructions comprise additional instructions to compress the second portion.
13. The non-transitory computer-readable medium of claim 10 , wherein the computer-executable program code further comprises presenting a preview of the media file at the user device based on the scrubbing input.
14. The non-transitory computer-readable medium of claim 10 , wherein the file further comprises existing audio, and the program code comprises processing the file to filter the existing audio.
15. The non-transitory computer-readable medium of claim 10 , wherein the computer-executable program code further comprises:
receiving an audio file at the user device;
generating a reversed audio portion of the audio file at the first time;
scaling the reversed audio portion based on the scaling factor to yield a scaled reversed audio portion; and
generating instructions for combining the video, the scaled reversed audio portion, and the scaled reversed video portion.
16. A computer-implemented method for producing a media file, comprising steps:
receiving a file at a user device, the file including a video;
presenting a representation of the video at the user device;
receiving a user selection indicative of a scrubbable portion of the video at a first time;
generating a reversed video portion at the first time based on the scrubbable portion;
receiving a scrubbing input and a playback speed at the user device, the scrubbing input indicative of playback of the scrubbable portion of the video in a forward direction and in a reverse direction;
generating a scaling factor between the scrubbing input and the playback speed;
scaling the reversed video portion based on the scaling factor to yield a scaled reversed video portion; and
generating the media file by combining the video and the scaled reversed video portion.
17. The computer-implemented method of claim 16 , wherein the generating the media file step comprises combining a first portion of the video that occurs before the scrubbable portion, the scaled reversed video portion, and a second portion of the video including the scrubbable portion and a remainder of the video.
18. The computer-implemented method of claim 17 , wherein the generating the media file step further comprises compressing the second portion.
19. The computer-implemented method of claim 16 , further comprising:
presenting a preview of the media file at the user device based on the scrubbing input.
