使用AWS弹性转码器，可以选择缩略图框架吗？

Question

我使用AWS转码器输出MP4视频＆amp; jpg海报缩略图。一切正常但缩略图始终是视频的第一帧，有时可能只是空白。我希望缩略图在2秒内被捕获到视频中。我无法看到任何调整此设置，有可能吗？

我目前的设置是：

while(x%y != 0 || y == 0);

Answer 1

You can define in the preset that you use for the Job : interval generate in thumbnails

Example preset for Thumbnails with 2 second interval :

Format jpg
Interval 2
Max Width 700
Max Height 394
Sizing Policy ShrinkToFit
Padding Policy Pad

• The tumbnail with the filename "video-00001.jpg" corresponds to the frame at 0 seconds.

• The tumbnail with the filename "video-00002.jpg" corresponds to the frame at 2 seconds.

• [...]

The file you need is : video-00002.jpg
