Apa sing bakal dibutuhake kanggo ngekstrak bingkai saka MP4 menyang JPG?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Bisakah aku ngekstrak bingkai ing timestamp spesifik ing MP4?
+
One at a time. Single Frame takes one time in seconds (for example 83 for 1:23) and saves that frame as a JPG. There is no field for a list of times, so run the conversion again for each extra timestamp.
MP4 videoku pribadi nalika ngekstrak bingkai?
+
Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted JPG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

No. The converter has no scene detection and no one-per-second mode: it saves either a single frame at the second you enter or every frame. For one image per scene, extract single frames at the times where the scenes change.
