The Gap

The Gap.

Both my video cameras creates Mp4 files 1.90GB in size when continuously
recording, so when placing two clips in order, there is a gap between the two
clips that when rendered is noticeable in the finished product. I can't get the
clips to touch because the first clip doesn't end right at the frame marker and
the second clip can only be placed a frame marker. (see attached picture).

I've tried creating a project in 60fps and importing the video clip recorded at 30fps,
thinking doubling the frame rate of the project would make the gap smaller and
less noticeable but it appears this isn't the case because regardless of how many
frames per second, Magix can't edit between 1/10 of a second instead of editing
frames. As you can see in the picture, the first video clip doesn't end all the
way through the last 10th of a second. My question is how can I work around this
problem? is there a way to edit frames instead of seconds. Would Video Pro X7 be
able to handle this problem?

Here is the response I got from Magix Support.

"Thank you for your message.

The files should be automatically joined on import. If this is not occuring then currently there is not a lot we can do, it is something we are already working on.

I can only recommend to join the files in Handbrake outside of the software:

Thank you for contacting Magix Support.

Any Ideas?

Thank you for your time

What make / model is your camera.

I presume the camera is recording to a memory card - if so do you have the software that came with the camera, there may be a program with it that imports the file parts and joins them together.

I suspect the reason MEP cannot join the videos correctly is because it is missing or cannot use the small data file, that some cameras store on the memory card, which contains the necessary syncing / joining data for the video files.

Hi John,

Both cameras are Canons, Vixia HFS20 and the other is a VIXIA HF-R60. The HFS20 has an internal 32GB storage and the camera wrights to a SDcard. The funny thing is I never noticed this problem until I got MEP2015, I'll have to fire up my old copies of MEP to see if this was there, to be honest, I didn't have these larger video projects before so it may not have come up before.

I'll take a look at the software that came with the cameras and maybe try capturing right from the camera with MEP

I'll let you know how it turns out, but I take it you haven't noticed this problem yourself?

Thanks

. . . . I take it you haven't noticed this problem yourself? . . . .

Not with my latest cameras - 2 Sony and a Contour sportscam - previously the only time I had this was with a one hour plus recording (that was an arm acher ! ) I did many years ago with a different camera, the software that came with the camera fixed the joining of the parts.

As someone who has two Canon HG10s and for which, any continuous recording lasting more than about 16 minutes gives exactly the problem (and for which no Canon-supplied software is available) I have used and can recommend the free tsMuxer available at http://www.videohelp.com/software/tsMuxeR

At first sight it might appear a little confusing but it does a perfect job or removing those "glitches" created when the camera begins to record a new file.

Thanks Emmrecs, You are right, it would seem the problem starts with the Canon Camera's, also tried my daughter's little cheap Canon camera and the results are exactly the same, but not with my old SONY DCR-DVD505, but the files are not MPG4, not sure if that makes a difference. I'll have to find another camera I could test with, I've tried 4 Canon camera's now, one was a DSLR. This is disappointing, as I'm looking to upgrade to Canons VIXIA HF G30, I love the Canon Video Cameras but this could be a deal breaker for me, but I still feel the problem could still be resolved in MAGIX if we could edit Frames instead of just seconds.

If Magix are truly, as they say "working on the problem", then that would be great.

Thanks for your help guys

Robert, I don't think the file format is relevant to this problem; I think it is one of the "characteristics" of Canon video cameras. I know they (Canon) apparently created an app which was designed to remove these "gaps" once the files had been transferred to computer, but Canon Support told me this app was not designed to work with my camcorder model (very helpful!).

Hence my research, discovery and use of tsMuxeR. Like you, I very much like Canon cameras (in addition to the two HG10s I also have an EOS600D) and I would not consider replacing the camcorders with a different brand until/unless they finally "give up the ghost". Have you tried running your files through tsMuxeR? Although a little confusing at first to understand (you need to add the first file in the sequence and then "join" others in the correct order and, in my case, output to "M2TSMuxing") I have successfully joined AVCHD files continuously recorded for anything up to 1.5 hours or more, which can then be imported, without any "gaps", to VPX5 for editing etc.
