Joining video clips - GH4 and others.
on Dec 14, 2014 at 4:42:06 am

Hey All,

Working with my new GH4 and it generates 4GB files for each clip than drops another one, when recording long shoots (I know many cameras do this), even though the GH4 use exFAT which will handle larger files. My Canon cameras do this, but they provide importing software that "seams" these clips to one long/large file. Since I am using a lot of clips and it is SO MUCH easier to move and sync one file vs tons, is there a software you all are aware of that will put these clips back together in order?
I have done some looking, but some don't deal with the 4k files.
I am on PC, Windows 7 64 bit Ultimate...

Thanks in advance for your help...

Have you tried using View | Device Explorer in Vegas Pro? I don't know if it will recognize this camera's cards but if it does, it should stitch the files together on ingest,

Hi John,

I move the files off of the card onto a HD, so nothing comes up under device explorer.
It would be great just to have one file as well, as I usually rename the clips by camera angle and such...
Are you aware of any "joining" software?

Thanks a bunch for all your input on so many topics!!

[Scott Francis] "I move the files off of the card onto a HD, so nothing comes up under device explorer."
What you need to do in the future is copy the entire card structure to your hard drive. It's not that much bigger than the videos themselves but it allows NLE's to still detect that it's a camera card and use the metadata to stitch the videos back together. What you did was the equivalent of taking the tape out of a DV cassette and throwing away the plastic cassette. You really want to treat the camera card structure as the whole container. Now you know for next time.
[Scott Francis] "Are you aware of any "joining" software?"
One thing you can try is opening a command prompt (CMD) and use the COPY command.

C:\> COPY video001.mts+video002.mts+video003.mts MyFullVideo.mts
This should concatenate the files into one. Try it and see.

Thanks John,

I will try the cmd prompt method.

I would state, however, that I am aware that Macs want the entire file structure, apparently now my NLE does too!!

Your comparison to a tape is odd that the one of the points of a non-linear format is to not have to deal with "keeping things in one place." I often have back to back to back shoots and don't have the ability to move files to a HD until all of them are done. Not being able to put them in separate client and file folders or even separate HD's is very frustrating and annoying let alone confusing. I don't have $75-$100 to have a chip for each client. Back in the days of $5-8 tapes it was easy to have separate client tapes. Also, once they where "flown in" I could name and put them where I needed to....Now, chips are awesome and so much easier to use, except in this case.

I appreciate all your help and will hopefully make out with the CMD method....

Best....

It's difficult if you are shooting multiple events on one card. I get it. Still when you archive the card to HDD, you should archive the while thing. Then use the Device Explorer to copy out on the clips you need for the project you are working on.

Here is my workflow:
I have my camera archives on a separate 1TB external Western Digital Passport drive (several of them actually). Then I use that to copy the clips I need to my internal HDD for editing. I also back up the 1TB drive to a 9TB RAID 5 so that I have at least 2 copies. I only have the clips needed for current projects on my HDD. Then they get deleted when the project is done to make room for the next project. Actually, they get moved to another 1TB external drive where I have all of my archived projects. This too is backed up to the 9TB RAID 5 so that I have 2 copies. So that's 2 copies of the original footage and 2 copies of whatever footage was used in a project.

This is what it looks like:
3 Drives: 1TB Archived Cards (multiple), 1TB Archived Projects (multiple), 9TB RAID5 General Archives

Camera Card --> 1TB Archived Cards
Camera Card --> 9TB RAID 5 /General Archives/Archived Cards folder
Finished Project --> 1TB Archived Projects
Finished Project --> 9TB RAID 5 /General Archives/Archived Projects folder

All this because we no longer have tape as a backup. :(

Hi John,
That is similar to what I do John, only I have some drives that are client specific. I shoot sometimes up to 15 camera angles, so my storage needs can be almost a TB for one project (also my Atomos files are HUGE but they look and work OH SO nice!!!.) Therein lies my issue with chips, but if I understand you correctly in using the "Device Explorer" will Vegas see the files as one clip? If so, does it join the split video clip (meaning one "scene: if you will that is cut into multiple files due to file size)? This is important because I will often have interns and such search the file for specific times that I need and they are not using Vegas (they will use their video player of choice).

My MAIN need is, if I shoot a 2 hour clip I need to be able to access THAT clip (scene) as a WHOLE file in multiple places, I do this as, I said before with the software called "Data Import Utility" that comes with my Canon cameras and it works really nice. I pop in my chip, open that software and import all the footage I have shot from a certain date. It joins all the individual clips (from one "scene") as it imports them to my HD. I am hoping that I can find something that will do this for my new Panasonic GH4 and make all this hassle disappear.

Appreciate your input as always...

Best

Sony Device Explorer stitches my Panasonic HDC-TM900 AVCHD video 4GB chucks together when I have a recording that is longer than about 20min in my case (1080p60). For example, I get a single 15GB mts file rather than 3 smaller files that I get when LightRoom imports from the same camcorder. The only thing you need to find out is if the Sony device explorer supports that camera, it does not work for my GoPro Hero 3+.

As Mark pointed out.. Yes it does. That's one of the great features of the Device Explorer. I shoot a lot of 2 hours events too so this was important to me. You get the event as your shot it (one whole clip), not as the camera stored it.

Hey guys,

Device explorer will not see my SD chip. It is from a Canon Vixia HF 30. Tried to insert the chip prior to opening Vegas as well as afterwards. Says no device connected. Also, I can explore in Device Explorer open up the SD card and even get down to the file level but my "Open" button is greyed out the entire way...any ideas?

Thanks

I see that the Canon Vixia HF 30 shoots both MP4 (35Mbps) or AVCHD (28Mbps). Which are you using?

Try shooting a bit of AVCHD and see if that makes a difference. AVCHD is an industry standard format. The card structure for all AVCHD cameras should be the same if they follow the standard. At that point, I'm guessing that the Device Explorer would recognize the card structure just like it does for Sony AVCHD cameras. It's worth a try.

I can try, but that doesn't help me with the Panasonic which IS the issue, I don't think it does AVCHD, just MP4 and Pro Res...I already have a workflow with the Canon, not the GH4....so I am back to square one...

For 4k, the Panasonic shoots MP4 and MOV...that is what I am trying to work through
It does AVCHD for 1080p BUT I cannot get the higher bit rates in AVCHD....

GRRRRR...

Thanks for your help in this!!!

I'm sorry I got confused. I thought the Cannon was the issue. I'm guessing that the Device Explorer is designed for video cameras, not still image cameras that also take video (for which there are no standards). I would ask Panasonic for software to fix this deficiency in their camera.

Thanks John,

It sees the chip/camera for the AVCHD in either the Canon or Panasonic. Neither show any other files in any format other than AVCHD. So ridiculous.....in 2014/15 with chips that can go to 512GB's we are limited to a 4GB sized file... (facepalm).....

Does anyone know of file joining software? One last time...

Hi Francis, how about "importing" the veg file that Vegas "pseudo combines" the MP4 (or MOV files)? Would this help? That is to say, on Vegas timeline, place all the spanned MP4 (or MOV) files you need, and save it as a project (veg) file, say, "joined" for the sake of this discussion. You then import the "Joined" veg file in another project file, in which case Vegas appears to treat the "Joined" file as a single video file. I just tested this using my GH4 spanned video files (MOVs) and they appear to be "seamless" (i.e. no gap in video or audio). I was also able to apply a video effect (in fact, a group of FXs) to the entire MOV files, which otherwise I would have done on a project media-by-project media basis.

That may work for Vegas, but I need this to be seamed together OUTSIDE of Vegas as well. I have need for a solid video clip from the get go, and really don't want to re-render anything...
Thanks for the idea!!

almost all the converters in the market can do such "MERGE" job, if you don't want to re-render them , just output as the origianl parameters.
