Seamless insertion of modified media content
Disclosed are various embodiments for seamless insertion of modified media content. In one embodiment, a modified portion of video content is received.

identify a video coding used in transcoding the video content;
identify an audio coding associated with an audio track of the video content;
dynamically adjust at least one of the start cue point or the end cue point to align the modified portion with the video content based at least in part on the video coding and the audio coding, thereby expanding the modified portion to include at least one of: a first unmodified portion of the video content at a beginning of the modified portion or a second unmodified portion of the video content at an end of the modified portion; and
package a video stream incorporating the modified portion seamlessly into the video content between the start cue point and the end cue point, the modified portion replacing an unmodified portion of the video content between the start cue point and the end cue point such that the unmodified portion of the video content is removed from the video stream.

4. The system of claim 1 , wherein the video stream includes one or more modified thumbnail images for the modified portion.
5. The system of claim 1 , wherein the instructions further cause the at least one computing device to at least select the modified portion from a plurality of alternative versions of the modified portion based at least in part on one or more user characteristics.
6. The system of claim 1 , wherein the start cue point is adjusted to align with a first key video frame in the modified portion, and the end cue point is adjusted to align with a second key video frame in the video content.
7. The system of claim 1 , wherein at least one of the start cue point or the end cue point is adjusted to align with an audio frame boundary for the audio track of the video content.
8. The system of claim 1 , wherein at least one of the start cue point or the end cue point are adjusted to align with a key video frame at a time location determined by a constant multiplier of time, the constant multiplier of time being determined based at least in part on the video coding and the audio coding.
9. A computer-implemented method, comprising:
receiving a modified portion of video content, the modified portion having a start cue point and an end cue point that are set relative to a modification to the video content to indicate respectively when the modification approximately begins and ends compared to the video content;
identifying a video coding associated with the video content;
dynamically adjusting at least one of the start cue point or the end cue point to align the modified portion with the video content based at least in part on the video coding, which further comprises at least one of:
dynamically adjusting the start cue point to be earlier in time so that the modified portion includes a first unmodified portion before the modification; or
dynamically adjusting the end cue point to be later in time so that the modified portion includes a second unmodified portion after the modification; and
replacing an unmodified portion of the video content with the modified portion such that the unmodified portion of the video content is removed from the video content.
10. The computer-implemented method of claim 9 , further comprising packaging a video stream incorporating the modified portion seamlessly into the video content between the start cue point and the end cue point.
11. The computer-implemented method of claim 9 , further comprising transcoding the video content and the modified portion using a plurality of video codings.
12. The computer-implemented method of claim 9 , wherein dynamically adjusting the at least one of the start cue point or the end cue point to align the modified portion with the video content based at least in part on the video coding further comprises aligning the at least one of the start cue point or the end cue point with a key video frame.
13. The computer-implemented method of claim 9 , wherein dynamically adjusting the at least one of the start cue point or the end cue point to align the modified portion with the video content based at least in part on the video coding further comprises aligning the at least one of the start cue point or the end cue point with an audio frame boundary for an audio track of the video content.
14. The computer-implemented method of claim 9 , further comprising:
determining a constant multiplier of time based at least in part on the video coding and an audio coding used to encode an audio track of the video content; and
wherein dynamically adjusting the at least one of the start cue point or the end cue point to align the modified portion with the video content further comprises aligning the at least one of the start cue point or the end cue point with a key video frame at a time location determined by the constant multiplier of time.
15. The computer-implemented method of claim 9 , further comprising:
identifying an audio coding associated with an audio track of the video content; and
dynamically adjusting the at least one of the start cue point or the end cue point to align an audio track of the modified portion with the audio track of the video content based at least in part on the audio coding.
16. A computer-implemented method, comprising:
streaming video content to a media player;
determining to replace a portion of the video content with a modified portion of the video content, the modified portion having a start cue point and an end cue point that are set relative to a modification to the video content to indicate respectively when the modification approximately begins and ends compared to the video content;
directing the media player to switch from the video content to the modified portion of the video content and from the modified portion of the video content back to the video content while handling an audio track misalignment, the modified portion replacing an unmodified portion of the video content such that the unmodified portion of the video content is removed from a playback of the video content by the media player; and at least one of:
dynamically adjusting the start cue point of the modified portion to be earlier in time so that the modified portion includes a first unmodified portion before the modification; or
