mp4 don't require re-encoding since these are native containers for AVC/h.264), but it will do re-encoding+joining into MPEG2 if you like. VideoReDo TVSuiteV4 will cut and rejoin into numerous containers (.ts and. I was using VideoReDo Plus before this for cutting MPEG2 ts files.so I upgraded. You can download a timed trial (lasts 15 days), but it'll run you $100 for a new license, or $50 if you are upgrading from a previous version of VideoReDo. The only reliable software I've found for this unfortunately is not free. I need to cut h.264 encoded transport streams (from HD-PVR). (Use case: removing commercials from TV shows.) Is there software that will let me do that without transcoding or re-encoding the video? I'm on Win normally but have access to Mac and Linux if necessary. Now I want to do some really simple cutting and splicing to trim off unwanted pieces.

I just got a Hauppauge HD PVR which records H.264 video in ts, m2ts, or mp4 formats. It's not an easy thing to program, I think. I imagine there might be a video editor out there that won't re-compress your whole stream, but I suspect it will cost you. So you have to re-encode.Īlternatively, you can end your cuts only right before Key frames, but then you have to decide, 'Am I going to leave small parts of the ends of commercials in? Or am I going to cut out a few seconds of the show?' But a lot of people think this looks crappy. So your video stream will look all wonky until the next KEY frame in the video stream comes along. If you cut somewhere in the middle of the stream of Update frames, then you've cut the Key frame and all the other frames the video stream is based off of. (think: right at the commercial break.) But you can only END your cut at a Key Frame. In order to NOT have to re-compress, you can START your cut anywhere in the stream. So think of the KEY frame as a starting point and then each UPDATE frame building upon the data from the previous frame. An UPDATE frame relies on the surrounding frames to give you a full representation of what that frame is suppose to be (so it takes up a lot less space).

(there are actually more types, but I'm keeping this simple.)Ī KEY frame is a full, unadulterated frame (it takes up a good deal of space).

Put simply, the video stream you're working with (H264) has to basic categories of frames: Key frames and Update frames. The tricky part is going to be the 'no re-compression'.
