Some of the commonly used video formats are MP4, MOV, WEBM, AVI, DIVX, FLV, 3GP, WMV, VOB and MKV. Any good video cutter must universally support all major video formats.

We all have different devices to record videos - smartphones, Go-Pros, DSLRs, Point and shoot cameras, HD video cameras etc. Well, there are basically three main features that a good video cutter must have: 1 - Must support a variety of formats But first, let's start with understanding what makes a good video cutter software. In this blog, we will tell you about the best video cutters in the market today - for desktop, mobile and online use. A good easy-to-use video cutter can cut out mistakes in the video, make camera transitions crisper and make the overall video more interesting to watch. I know/ can work out the commands for (2) and (3), but am unsure about what commands are needed for (1).As we keep sharing more and more videos online and with our loved ones, video cutters have become an important tool to have on our devices. (3) ffmpeg concat the first short clip (the 5 second one).without re-encoding, using -vcodec copy.

then cut this to get the 5 seconds from 0:01:35 through 0:01:40.

Including one at the target time of 0:01:35

but the video is blank/ black for the first 5 seconds,.

using -i blah.mp4 -ss 0:01:35 -vcodec copy, what results is a file where:.

this starts both the audio and the video too early.

Using -ss 0:01:35 -i blah.mp4 -vcodec copy, what results is a file where:.

NOTE: See scenario, and my own rough idea for a possible solution below. Thus, would like to maximise the use of -vcodec copy. I would like to cut a video at the beginning at any particular timestamp, and it need to be precise, so the nearest key frame is not good enough.Īlso, these videos are rather long - an hour or longer - so I would like to avoid re-encoding this altogether if possible, or otherwise only re-encode a minimal fraction of the total duration.
