 Hi,

 As per the FAQ (https://www.ffmpeg.org/faq.html#How-do-I-encode-single-
 pictures-into-movies_003f) there is a "-start_number" parameter that can
 be passed to start the encoding at a given frame/image sequence number.

 I wish that there would be an "-end_number" parameter that could exist as
 well.

 It would permit us to encode a portion of an image sequence.

 At my studio it's normal to have 50 thousand frames in a given scene.
 With that added parameter it would allow us to script ffmpeg to encode
 without moving/copying the rendered files selection in another folder.
 The current behavior is to encode until there is no more files matching
 the digit (%d) parameter in the working folder.

 Thanks.
