Easy script for drag&drop merging of spanned AVCHD .MTS files (in Windows)

MrZz — Mon, 02 Apr 2018 12:15:02 +0000

Today I needed to merge some spanned AVCHD/MTS files (because of the 4gb file soize limit on the fat32 capture card) together into one on my workstation. I just searched for this script which I normally used but since I couldn't find the script on my system, I rewrote it and thought I'd share it. Just for everyone else who has some use for this handy little script here's the code:

echo off
title Merge Files

set /p choice="Enter path to merge to: (eg. C:\video\test.MTS)"

if "%~1"=="" exit
if not "%~1"=="" SET one=%1
if not "%~2"=="" SET two= + %2
if not "%~3"=="" SET three= + %3
if not "%~4"=="" SET four= + %4
if not "%~5"=="" SET five= + %5
if not "%~6"=="" SET six= + %6
if not "%~7"=="" SET seven= + %7
if not "%~8"=="" SET eight= + %8
if not "%~9"=="" SET nine= + %9

copy /b %one%%two%%three%%four%%five%%six%%seven%%eight%%nine% "%choice%"

echo AVCHD Joining Complete.
pause

Just copy this code into a .txt and rename into .bat. Then you can just drag and drop the files, by selecting them and drag the first one on the .bat. You will then be prompted to input a destination path and name. You can merge a total of nine files into one this way.

Cheers!

GH5 froze during recording, resulting in unreadable mdt file

SuperTinyMagnet — Thu, 04 May 2017 12:30:06 +0000

Hey folks! I need help repairing a video file. The other day during a professional shoot, my new GH5 froze up when I hit the record button to stop recording at the end of a 23-minute (!!!) interview take. Even after flipping the power-off switch, the camera stayed on and frozen. I had to remove the battery pack. Now I have an unreadable/unfinished .mdt file that can't be read or played back. Has anyone run into this before?

I'm also wondering how I can prevent this from happening again. I was shooting 4K 10-bit 23.976fps using a Lexar U3 150 mb/s SD card with 128GB of storage (I had used 122gb by the end of the take, and had a few gigs to spare.) I was also using a 3rd party battery by Newmowa, but it had plenty of charge remaining.

Thanks for reading! Any leads at all would be hugely appreciated.

Gh4 on FCP7 File size problems

Nic — Sat, 15 Apr 2017 12:57:18 +0000

Hi,

I just bought a GH4 and I am trying to get it to work with my FCP 7, but is does not really work well yet. I prefer to film in FHD 100Mbps 25P, and I need to film longer than 30 min..The camera is bought in US and does film continuously more than 30, but it chops up the files in small pieces of 4.27GB (6.40 min). There are 2 problems in this: 1) When importing in FCP7 it imports well, but when put on the timeline, "General Error" appears and it will not play it. I have tried to convert to ProRess HQ, and this plays well, but a second problem appears: 2)every 6:40 min I lack 2 frames both audio and video, and this is really not what I need, I need a continuos file for more than 6.40 min...

What can I do?

Fastest File Sharing Site

matt_gh2 — Sat, 19 Jul 2014 20:49:59 +0000

I'm looking for the fastest file sharing site for fastest downloading and uploading. I'm used to Google Drive, but someone sent 5GB from Dropbox and it was downloading at 200 Kb/sec, which would've put me at 9 hours. I'm wondering what everyone likes for file sharing for video editing file sharing. Thanks.

Panasonic LUMIX GH4 Duplicate File Names in Successive SD Cards

RobShaver — Tue, 08 Jul 2014 16:19:47 +0000

This is my first post here so let me know if I'm not doing it right.

Has anyone else noticed that the GH4 produces duplicate file names on some of the video segments in successive SD cards?

For example I often shoot events where I fill an SD card, stop the recording, swap to a new SD card, format it in the camera and then start recording again. (I'm recording in 4K cinemalike-D mode.)

For example here is a path to the contents of one SD card:
E:\media\2014-06-25 AAG\Day-1\Reel-1\DCIM\102_PANA
and here is the directory listing in that folder:
P1020168.MOV
P1020169.MOV
P1020170.MOV
P1020171.MOV
P1020172.MOV
P1020173.MOV
P1020174.MOV

The path to the contents of the next SD card:
E:\media\2014-06-25 AAG\Day-1\Reel-2\DCIM\102_PANA
and it's contents:
P1020174.MOV
P1020175.MOV
P1020176.MOV
P1020177.MOV
P1020178.MOV
P1020179.MOV
P1020180.MOV
P1020181.MOV

Notice that file P1020174.MOV is the last file in the first SD and the first file in the second SD. I really prefer unique file names without regard to what folder they are in.

Since Adobe Premier Pro CC does not, on import, combine the clip segments in to a single clip like it does for other cameras, I discovered this file duplication problem when building full clips manually and got the files confused.

Trouble copying SD Card to Computer, but can play the file directly from the SD Card no problem.

I used GH2 Driftwood hack Cluster X Drewnet 12-15 Classic GOP. I was using a class 10 64 gb card. I only used one file for like 20 minutes. It stopped recording and said I have exceeded the files able to record or something. So in a quick panic I switched to a 32gb sd card that was not class 10. It recorded fine for the few minutes I needed to finish the interview with my subject. But then it said, "cannot write to card due to writing speed of card." (I'm paraphrasing). Anyway the record button kept flashing and no matter what I did it wouldn't stop writing to the card. I waited a few minutes and nothing changed so I pulled the battery out. I went to my PC Windows 7 computer and inserted the card. It plays back just fine but it won't let me pause or rewind. I saw the video it looks great, but my computer will not allow me to copy it to my computer. The error message I get says, "An unexpected error is keeping you from copying the file. If you continue to receive this error, use the error code to search for help with this problem" Error Code: 0x80070570: The file directory is corrupted and unreadable" I tried to see if I could put the file in Adobe Premiere CC. The reason is I was going to try to export it as a new video but the import process alone caused the whole computer to freeze. It's a desktop and very fast.

Any ideas of how to get my file off of the sd card? I'm scared to remove the sd card from the reader attached to my computer. (WRITTEN ON TUES. JULY 9, 2013 at 4:37pm Eastern Standard Time, U.S.)

Please HELP: Why can't iPad 4 read this file?

PCortacans — Thu, 14 Mar 2013 16:36:33 +0000

Can anyone tell me why is iTunes telling me this file cannot be read by my iPad 4? I believe if fulfills every single one of Apple's specs (except maybe audio bitrate).

Thanks for your help!

GH13 Concert and Event settings 24p with file spanning

DrDave — Sun, 04 Sep 2011 17:22:19 +0000

I'm starting this thread for people who are interested in a high quality, 24p, stable patch for events such as weddings, concerts, theater, poetry readings, lectures and so on. And pub crawls. Maybe impossible, but progress continues to be made.
Although not always high art, I get a lot of requests to video a show, concert, event, wedding, etc., and these events typically are indoors, with poor or varied lighting.
Sometimes these events run several hours. And for these events, I sometimes prefer the IQ of the GH13 over the GH2, at ISO 400-1000.
My requirements are:
24p for easy editing in Premiere and others. Premiere offers real time playback and effects with Mercury engine.
Reasonably good IQ, regardless of the bitrate
Minimal pulsing (some ppl don't see it but it drives me nuts)
Fine grain at ISO 800 and usable 1600
File spanning, in case I need continuous coverage
Smooth transitions in shadows, given the limitations of the camera.
Ability to use F/5.6 on a sharp lens in places that have good lighting
Good IQ and grain with lens wide open in bad lighting.
Plays back in camera so the highlights ("overs") can be checked, and also IQ checked on a monitor.
Static scene bit rate 0f 20-24, typical of events and shows, or stages where there are a lot of fixed objects or open space
Works on a Transcend 32gb Class 10 card or better

First off, I would like to acknowledge all those who have done the real work, including Vitaliy, cbrandin, lpowell, blackout, rigs, and many more.
Basis line: my starting point was the BP patch and lpowell's amazing high reliabilty patch. The HR patch has really served me well. It file spans reasonably well, has great IQ. It does not of course have 24p (hence the reliable part). The BP patch is also great, and is 24p, but did not span reliably. Another issue is that high bitrate patches often give low rates in low light. And theatre lighting with F/5.6 would occasionally lock up at 24p.
Along came the rigs patch, which gives HIGH rates in low light and static scenes. My static scene bit rates doubled. Also, pulsing in shadow areas is minimized.I made three changes to this patch. First, I used the suggestion to raise the buffer to 84. Next, I lowered the overall bitrate in the regular section to 36 and the minimum to 22. I found that I could not see a big difference in static scene rates of 24 as opposed to the 33 I was getting in Rigs. Also, after a certain point it seemed that noise in shadow areas became slightly more visible after the bitrate exceeded 24.
So far, in three days of testing, quality is good, file spanning is good and I get a solid 24 minutes per 4 gig chunk on my card--the reasonably priced Transcend 32gb. Mileage plus.

Like all 24p patches, I suspect it will crash, so those who really need reliability should go for lpowell's high reliability patch. As with all patches, use at your own risk.
I'm sure those better versed in the subtleties of the patch can make a better one, and I welcome suggestions.

The zip file has the most conservative version of the patch. I will try to bump the bit rate up ten percent with the same stability,and also work on possibly a GOP of 8 or 6.
