I had to do that to figure out what it does and how it does it. Had I not done that, I too would have found the camera difficult. I also read the camera manual a few times.
infamous did not say, so I can only guess at a solution. First, he's mad at digital video file limits that trace back to Microsoft. Panasonic (and Sony) understands and to overcome those limits provide software. To get it to work right, you have to use Panasonic software to move the files to your computer and do it the way the book says to. The reason is that with each file are a couple extra small mystery files that have no other purpose than to help HDWriter do what it does. Without the full set or modifying the originals in any way, HDWriter gets stubborn and erratic.
My first step after shooting is to use HDWriter to transfer and catalog clips. I may join and trim some. It always makes new copies. The originals are left untouched. Even if you trim an original, there is a copy. That copy also has the extra mystery files. If all I want to do is trim and clip a little, I go no further. If I want to get beyond basic file handling and simple editing, I use another editor.
The reason I'm guessing that this is the reason infamous is having trouble with HDWriter is because I've not read anywhere that anyone else is having trouble joining and trimming clips. There are some long threads here on Panasonic camcorders where owners are using various versions of HDWriter as there first workflow step and it has not come up.
A tip for infamous: the AVCHD 1080p60 bit rate is variable so there are peaks above 28Mbps. A guy names Cebu used to post here a lot found that when there was a peak above some level (40?) his PS3 choked. It really angered him. If the goal is true 1080p60 reliable playback on a HD TV it may be necessary to spend $100 on a dedicated media player known to be made for that, like the WD TV Live. Another way is to use the camera itself. One of the weird features of HDWriter is that you can put clips, or joined clips, back on the SD card in the camera. Your camera and a collection of SD cards can be a flawless 1080p60 media player with a simple HDMI cord for connection to the TV. Earlier versions in the V700 family came with a remote for this function. Maybe the V700 has a remote.
Yes, my major issue would be easily solved if HDWriter worked the way it should. It can easily join and trim without re-encoding and it does it fast. But when its done, and your final product is still over 4GB, HDWriter will STILL split the file into two (one 4GB and the other with whats leftover). For example, with this camera, I shot one 35 minute clip which was about 6.2GB. Due to the 4GB limit, the camera separated the files in two (4GB and 2.2GB). I used HDWriter and joined them, and trimmed a few minutes that I did not want. The result? Instead of a 4.5GB file, HDWriter made a 4GB and a 512MB files. Ugh! Had HDWriter made it just one 4.5GB, I would have been fine with it. But now I have to use tsMuxer to join them. Isn't that redundant? Shouldn't technology reduce my steps? Sure, I can trim with tsMuxer, but it doesn't show any video in the program. I have to open some other program, count the minutes and seconds what I want to keep and input that information in tsMuxer. What was Panasonic thinking about when they gave us some broken product?!
The V700 has no remote that I know of. I wish it did - that would have been a very good addition.
I suppose if I want to watch them on my HDTV, I'll have to purchase a HDMI that'll fit the camcorder to the TV because the PS3 is lacking. You may be right about the PS3. When watching it and having it show the Mbps, it'll play fine, but as soon as it jumps around 30Mbps or more, the video gets a little choppy and then the Mbps dips down to about 7.6Mbps and stays that low. If I pause the clip and start it again, it'll then go back up to the 20sMbps. But when it slowly gets into the 30s, it starts all over again and jumps down to about 7.6Mbps and stays there until paused.
My other frustration is the playback on a PC (which I'm sure it can be solved - somehow...). This may be a little off-topic, but this camera does record in this high m2ts setting, but playback of these files is too tricky. I just wish it'll play it back perfectly on my PC. But no program ever seems to run it properly. Media Player Classic (32 and 64bit) will run it smooth, but in full screen the audio is delayed OR the audio will skip/pause for a split second here and there (when played windowed, it plays it fine). Windows Media Player runs the sound perfectly (even in full screen), but the video is choppy. I've tried various renderers in Media Player Classic (EVR: CP, Overlay Mixer, Haali, etc), tried various splitters (LAV, Haali, System Default, etc.), tried frame time correction, updated all video and audio drivers and updated all codecs (K-Lite Mega Codes), but still nothing seems to run these m2ts files in full screen any good that this camera generates. All other video files will run perfectly in full screen except the ones that this camera makes.
Any ideas or comments will be appreciated.
EDIT: Now Overlay Mixer Renderer seems to allow the M2TS files to run smoothly and without any audio problem in MPC. However, It seems that I have to manually change it back to EVR:CP when playing things like a 3D MKV file because that file will be choppy. Seems I can't win.
EDIT 2: Good news. After fooling around with some setting in MPC, I found out what works. Under Renderer Settings / VSync, it was checked for Accurate VSync. I unchecked that and checked VSync and Alternative VSync and now M2TS files run properly in full screen under EVR:CP.
