Greetings dakotase.

There was a post by hazydave on the topic of joining clips, but he did not reply when asked to clarify. Perhaps you could answer on his behalf.

Many thanks and best regards.

So if you drop 00001.MTS and 00002.MTS onto a timeline, there's going to be some mess there at the boundary. What I'm doing is a dumb catenation, which is exactly what you want to fix the issue. I believe that's what Ken's program does, too.

There's no need to analyze the file contents. A program like TSMuxer, or other video-aware program, is not the right answer here, unless it's specifically designed to detect this situation.

Greetings Dave.

I noticed when using HDWriter the playback is seamless.

Just to clarify, are you saying there will be glitches if different segments are joined together using tsMuxeR?

If so, will the dos command copy/b work?

Many thanks and best regards.

I have never tried tsmuxer to SPLIT a clip, only to JOIN clips. I don't know off the top of my head if it can. I guess when time permits I'll take a look at it.

Just a note though that when I join clips such as avi files using cat command, I fix the index using mencoder to fix audio index

Oops. I meant using tsmuxer to join the clips. Apologies.

Did you get identical files using both methods?

I didn't use it. I've used it in the past. Just copy files in binary mode. Maybe the tools I'm using are not that sensitive that when it sees another header in the middle of the file, it just ignores it.

Most of the tools I used are open source. I'm doing all the processing on a linux machine.

1920x1080 @ 59.94 fps(aka 60p) is impossible even at the lowest bitrate. The plasma doesn't see the file.
1920x1080 @ 29.97 fps progressive, 40mbits works really well, no stutter
1280x720 @ 59.94 fps progressive, 40mbits works really well, no stutter(I like this a lot, very smooth)
1280x720 @ 59.94 fps progressive, 62.5mbits works but with stuttering

This plasma hdtv is 2 years old so it's ok. I'm sure by the time I buy a new bd player or hdtv, 60p playback will be standard.

Let consumers dictate the technology and companies will listen to us. hehehe

Did one quick test last night. Re-encoded a native 1920x1080 59.94fps, 26mbps .mts recording to an H.264/MP4 format 1920x1080, 29.97fps, 30mbps, burned it to DVD+RW disc using the AVCHD directory prepared by multiAVCHD tool. Playback was smooth on my Pioneer BDP-320 player. No stuttering, no audio loss. I'm sure bitrate was close to 30Mbps when I created the file. I'll recheck again tonight.

I'll try another test using 40mbps bitrate.

I've only had one sequence grow over 4GB (about 22min) so far and just used binary copy to join them perfectly. From a DOS box you just "copy/b In_1.m2ts + In_2.m2ts output.m2ts". Note: PD9 is unable to join them without an audio drop.

I used to do that, but someone told me that some utilities like MediaInfo do not report correct playback time, and some players play only for as long as the first clip goes. So now I prefer using tsMuxer for clip joining.

Great thing testing is going on out there
One question : I never used multiAVCHD : Does creating dvd directory means that its a dvd with menues, chapters and so (or is that data type dvd)

About stitching, Writer 2.1 seems to do a good job ( though I tested with only 2 files )

Streeming - playing original 1080p 50 in data type format is possible through new sony bdp 370 or 470 like was said in this forum. (through a usb flash drive or hard drive and even making a data dvd can do it ). This is a good answer for many persons not used to video editing (or not having time for it ) and still wanting the best right away video quality provided by this cam.

Its good to seek for limits : I had some issue with 1/25 shutter speed that gave stutery dvd . The same video was «quiet readable » with usb flash drive (though with bad noisy sound).

multiAVCHD supports menus. I created a dvd of our Christmas Party. However, I'm still trying to figure out why my chapter thumbnails are blank. Each chapters plays perfectly though. You can see screenshots of menus from here, http://multiavchd.deanbg.com/tutorial.php

I will try PS3 one of this days. I was told that PS3 support bitrates upto 62.5mbps but I'm not sure what the frame rate should be.

If I encode at 1080@59.94, it will stutter but not with 720@59.94 even at 40mbps. Btw, I noticed that we can actually see the difference between a 720 video and a 1080 video on a computer monitor. 720 is a little softer but it's still very nice. However, playing them both on my 52" plasma, I could hardly tell the difference in terms of resolution specially on a still scene. The 720@59.94 though on fast moving objects is awesome.

I am surprised on your Panny 52" Plasma..
I have a Pioneer Kuro 50" Plasma (Great Plasma but no Longer Produced) and it plays 60P files perfectly with no Stutter etc...
I also have a Vizio XVT3 Series that also plays 60P with no problems.
I am as sure as you are that any HDTV's Produced today should show 60P

How did you prepare the video? What resolution and bitrate? Was it in avchd format?

Disregard, I saw your other posts regarding playback of 60p files. You mentioned there you were using your htpc to play those 60p files.

The TM700, and most better digital camcorders on the FAT32 file system (which is responsible for the 4GB system... FAT32 is required by the SDHC memory card format -- you can avoid this if you go to SDXC), don't drop a single bit when switching files. They simply close one file and open the next.

And that's fine, when you know it, but a better solution would have been to drop the file on an I-Frame boundry. As is, you have to concatenate the separate files, at least that's the safest approach (I used "cat" in Cygwin, v1rtu0s1ty may be using real UNIX, but the idea is simple: you're simply copying multiple files, as-is, into one).

I don't know if higher-level programs would do this correctly. You'd hope something like TX-Muxer would, but I can't verify that. Since TX-Muxer understands the MPEG-2 Transport Stream format, there are several options available. There may be something in the docs that explain just what they actually do.

Ok.. I have been shooting some timelapse video, largely to go with a music video I'm working on. The TM700 helps out here very nicely, versus "DSLR with intervelometer" or some such.

Just today, I was shooting the minor snowstorm we had here in South Jersey, and discovered the catch -- it's limited to 12 hours?!?!? That's realtime, not based on the 12 minutes of video I had captured. What kind of moron came up with this artificial limit. Argh! Why any limit at all... if I run out of power or storage, that's that. Are there other weird artificial limits in the TM700 I don't know about? Is anyone hacking the firmware (ok, I know, this isn't a Canon...)

I'm very interested in the number of hours you recorded. Did you really record in 12 hours continuously?

You would think that makes sence as the header would not but re-written but I just checked - both Media Info and Windows correctly reported the stitched together file as 33mn and it plays over the join perfectly in both apps I tried.

12 hours of a Snowstorm?!
I live in Rochester, NY and I have also taken some Snowstorm footage, both out my back Sliding Glass Doors and from my Vehicle while driving in it.
But 12 hours...WOW!
What size file and Quality are you shooting?
It can't be in 60P, that would be a huge file.

When would you watch 12+ hours of Snow?
Isn't that right up there with watching Ice Melt! LOL!

I think that Panasonic probably thought..What could someone possibly shoot for 12 hours continuously? Well, you just told them....
Also one Stop and Re-Start in a 24 hour period does not sound very time consuming.

This is a problem that I will gladly never have..LOL!

You Go Man!

I think he was saying that the camera would only stay "ON" recording for 12h even though it was time-lapse mode (12-min video or one shot every hour).

Will this model do that wouthout creating for me issues that a novice cannot resolve?

I have a Panny 65" V10 plasma that also has an SD card slot and I can play directly through that I suspect..

Any help that can be provided will be appreciated.

Thanks

I have the TM700 and have read many posts from many forums and so far nobody has got the 1080 60p files to work on a mac. People are having to convert to 30 fps to use on Macs.

Hi v1rtu0s1ty & Shadowboricua,
Yea, my post was for HazyDave...I did not read back far enough to see that it was for time-lapse video...
Never mind...Long day yesterday..
One of those Fridays from Hell!
I guess I'll keep that 12 hour window in mind if I ever do Time Lapse...

Sorry about that...Let's move on...LOL!

Maybe that 12 hours limit of continuous use was implemented because Panny engineers were afraid that the camcorder would overheat due to lack of proper air flow inside the unit, even though they used a fan ? Has anyone noticed that when the camcorder gets hot, there is no warm air coming out anywhere even if the fan is still pumping fresh air in? Unless you open the connectors door, or the shoe flap.

Anyway, I agree that a time limit in time laps recording mode is kind of stupid.

I thought I would post again, since someone might know how to resolve this. When I sit the TM700 on a tripod and turn the auto features off except for auto-focus, I get a problem that every now and then it tries to focus and the recorded image moves and then goes back to normal. This looks very horrible, as you can imagine, and without auto-focus I get blurry video. I am recording myself sitting at a desk talking. The camcorder and auto-focus is great with the exception of this glitch. Is this something unique to mine and means mine has a problem, or is this standard? Does anyone know of anyway to get auto-focus to work without doing this moving of the screen randomly when trying to refocus? I would greatly appreciate any help or advice.

Yeah, I had that surprise several months ago when I had a bit of too much time.. I hooked up TN700 to mains power, and let it record the whole day. I've read the 12h limit in the manual, but wasn't sure if limit was 12 hours of video file or 12 hours of having camera turned on. I was disappointed like you when I found out that it's 12 hours of having camera turned on and recording in time lapse mode.. That's just stupid, and not even overheating can explain that, things that heat up get to their maximum temperature after much less than 12 hours, so that couldn't be it. It's just nonsense and just a stupid decision. They probably thought no one would need more than 12h. Well, Maybe I wanted to shoot a whole day (24 hours, and indeed I did want that), and all I'm left with is doing it manually after 12 hours. Stupid :P

There is one possibility though, I've noticed that my file was 22 minutes 15 seconds .. That's roughly the time that camera usually switches to another file when I shoot in 60p mode. But on the other hand, makes no sense, because in 60p mode that's the 4GB limit, and in Time lapse (30p) that's just 2.xx GB ..

Anyway, sorry for rant, but your post reminded me of the stupidity of it... so I just had to

It could be for all manor of reasons but I suspect it is because these cameras are not designed for 24/7 duty usage so have a limit to stop them being used in such circumstances, like CCTV.
