Since all of my files used the same codecs, I used the first example in the document above. But I want to merge all of the clips into one file when I'm all done. Every time you hit the pause button, you get a new file, which is ok. How to concatenate (join, merge) media filesīy the way, in my case, I was trying to concatenate 150 files from my Canon HF M50. Here is a link to the ffmpeg documentation describing how to join. I had to download the latest version of ffmpeg for this to work. I have had similar problems to others with the audio sync problem, but I just tried this using the -f concat option with ffmpeg and it worked - with no audio sync issue. I have finally found a solution to this issue that worked for me. Once I get my pc running again, I will look at the program you recommend. I have gotten a reply from AimOne (NOT same as Aimrsoft lol) about their splitter/joiner recommending I install the K-Lite Codec. Some of these programs including this one use the NVidia GPUs to accelerate encoding and it is conceivable that this is related, as I did notice during the reboot and fix-attempt sequence one blue screen involving the video driver. It's possible this is a pure coincidence and there is a hardware problem. Several reboots and tries later, with freezes occurring pretty much upon doing anything inside that program, my machine no longer makes it thru the Windows startup even the startup recovery has failed my computer is now effectively dead. Then, when I cancelled an operation, it froze my machine. It appeared to actually work correctly (it's about $60). Yesterday, I tried Aimrsoft's program " Total Video Converter". I've been evaluating programs which give free eval copies. I'm willing to spend reasonable money - I don't demand free lol. Even modest testing in the lab should have revealed these problems. Overall software quality in this field appears to this engineer to be shockingly low. All other programs I've tried for that latter functionality failed in some way within minutes of my trying them. mp4 correctly, but has no splitting or joining capabilities. So far, I haven't seen one program that correctly does it all. I'm actually willing to pay for a good solution to general conversion, splitting, and joining, but it's nice to be able to evaluate them first. VOB files correctly it will often tell you that a file of 24 mins duration, say, (which plays fine in other programs) is of 2 mins duration, or sometimes zero and that's all the program will recognize. Failed after merely 10 secs of testing.įreemake: failed a test but I don't remember which.ĬUDA video converter: cannot load. Only problem was it consisted of 24 mins of black frame, which was not the original!ĪIM's splitter-joiner: couldn't even open an MP4 file, simply said "cannot play ". Once I got that part to work, it split off the section I wanted and saved it. It would often get into loops of the form "can't advance to point " from which the only escape was to use task manager to terminate the program. and I'm a VERY experienced software engineer.Īvidemux: extremely confusing, had a lot of difficulties synchronizing on a key frame. Hello All! I've tried a number of these programs most of them simply don't work.
