Toshiba Gigashot GSC-K40HE HD - Playback of MP4 files

Need help please.
I have a Toshiba Gigashot GSC-K40HE HD camera and have bought an Iomega ScreenPlay Plus HD Media Player, basically a 1TB hard drive with the ability to play back MP4 files that the GSC-K40HE produces through the HDMI cable direct to my TV.(http://www.iomega.com/support/manuals/hdd2009/scrnplyplus/en/main.html)
The files have been tranfered successfully onto the ScreenPlay Media Player, checked through my laptop the MP4 files open properly.
However when connecting the ScreenPlay Plus HD Media Player to the TV with the HDMI lead, when selecting the MP4 files a message comes up as 'Unknown File' and won't won't open.
My questions are:
1 Why won't the MP4 files play?
2 Is there another format that they need to be saved in for them to play, if so what ones
3 Looking at the GSC-K40HE HD camera files there is a 'THM' simultaneous generated with the MP4 file when a video has been taken, what is this and could this affect the playback through the ScreenPlay Media Player?
4 Does anyone know of a storage device similar to the ScreenPlay Media Plus that I can just copy and store my videos, plug and play back through my TV without the above happening.
Look forward to your replies.
Thanks

Hi buddy,
Fact is if you can open the recorded files on your notebook the videos are ok and the its no corrupt video file so in my opinion the problem must be the external HDD where you store the videos.
Have you already tested different videos not from the camera? You should test it with other mp4 files and other file types to make sure the external HDD is working properly.
If its necessary I would contact Iomega directly. Maybe there is a firmware update for this media player or some settings that you have to check to make such recorded videos working.
I would also test another cable.

Playback of MP4 file on 2 different Macs/Quicktime versions look different

I created a MP4 file from a Motion project (the project has been transferred between my MacBook Pro on Leopard and my iMac which has Snow Leopard).
On my iMac the file shows 156MB, and I use Quicktime Pro 10.X (its at home so not sure of what version) and the file comes up at 1280x720 as intended.
I then copy the file to my MacBook Pro which has Quicktime Pro 7.6.6 (I thought installing FCP included latest QT Pro Player??). The file size shows up as 149MB, and when i play the file back it comes up squashed, as in it's squashed at the top and bottom. So a circle looks oval now.
When i try and export on my MacBook Pro - i get the squashed image straight away.
I dont understand how this is possible? Can anyone shed light on whats going on? Is it the different QuickTime Pro versions?

I dont understand how this is possible? Can anyone shed light on whats going on? Is it the different QuickTime Pro versions?
Sounds like what you are seeing basic difference in the way the two versions of the QT Player display the aspect ratio. Beginning with iMovie '08 thru iMovie '09 and on into QT Player X, the display dimensions are determined by the by the pixel aspect ratio setting and not the the "Current Size" setting data embedded in your file. QT 7, on the other hand, relies on the "Current Size" sitting to display the movie. When these settings equate to different dimension, your movie will display differently depending on which player you are using at any given time. The easiest way to corrent this problem in your case, is to simply open the movie in QT 7.6.6 Pro, reset the display scale to 1280x720 in the Video Track "Visual Settings" tab in the "Properties" window, and then save these changes. Thereafter, the movie should play correctly in either QT Player. If things had been reversed and it was the pixel aspect ratio setting that had been erroneous, then you would have had to re-compress the file embed the correct aspect ratio. This is also why your QT v7.6.6 attempted exports reproduce the error since it is passing the incorrect scale dimension on to the new file you are creating unless you manually modify the output dimensions.

Toshiba Gigashot A40 - AVCHD not read by Imovie'08

Hi,
I'm a new user of this Forum.
I just bought a Toshiba Gigashot GSC-A40FE Full HD AVCHD(Format MPEG4 (AVC/H.264 H)).
Does anybody have the same camera ?
When i open Imovie'08, it crashes !
Is there a way to capture my sequences on Imovie'08 without converting ?
An idea ?
Thanks a lot.

Hi Nico,
I don't think Imovie'09 solve that problem, but if it does, please tell me !
Otherwise, You can convert the video with VIDEOPIER HD or MOVIECONVERTER, and then import your video in Imovie'08.

HDMI Cable for Toshiba GigaShot 40

Hi,
I bought Gigashot Camescope, and a new TV with an HDMI port.
The HDMI port of the Camescope Toshiba GigaShot 40 is thiner than cable for my TV.
First: is it a real HDMI port? or an i-Link/Firewire port?
Second: how can I use this Camescope HDMI Port to connect it to my TV on my TV HDMI Port?
Third: where can I buy Options/Accesories for my Toshiba Camescope GigaShot 40?
I'm living in FRANCE.
Thanks, for your attention.
Regards

Hello Dragon2010,
to your questions:
- first: yes it is a real HDMI-port but it is a Mini-HDMI-port.
- second: So you need a "Mini-HDMI to HDMI Cable". Its not included.
- third: you can buy options in electronic stores like "Media Markt" and so on but the best way is around the www.
hope this helps you
best regards

Jerky playback of rendered mp4 files in Premiere Elements 10

I am editing GoPro Hero 3+ MP4 files in PE10 and exporting to AVCHD MP4 (H264 1920x1080p 30) but the resulting file does not play smoothly, almost like it is missing or skipping a frame at regular intervals. When rendered to M2T (H264 1920x1080i 30) or other AVCHD formats the playback is smooth. Why can't I export to the same format as the MP4 source files? FYI, I'm using PE10 on a Win 7, 64 PC with i7 and 16gb ram, and program files on a SSD separate from the HDD containing video files.

Thanks for your reply.
Attached is a screen shot of the general preferences.
When I imported the first GoPro MP4 file into the time line, PE10 gave me a message that the project settings did not match the source file, and asked me if I wanted it to change the settings, which I let it do.

Toshiba L4353 39" - USB Movie Playback Problem

Hi,
I recently bought a Toshiba L4353 39" smart tv, the usb playback does work but i keep having this really annoying problem,
basically i'm watching a movie file and everything is fine and then for no reason the playback of the file stops and i'm back at the my content screen, this has happened on multiple films and have tried a few different HDD so i can only assume it's the TV, help?
Thanks, Martin

Did you test the movie playback using an USB flash memory stick or just USB HDD?
Does this issue appear playing movies supporting different file format?
In the [user manual page 89|http://www.toshiba-om.net/LCD/PDF/English/L4353-323950-English.pdf] you can find information about the file compatibility
Please check if the movie files are encoded properly and use the supported video and audio codec

Problems exporting and playback the MPEG2-DVD videos, from .MP4 file!

I have PremiereProCS4 v.4.2.1 installed on this PC:
OS:WindowsXPProx64Bit; CPU:IntelCore2Quad Q9650; RAM:4GB DDR2 PC2-6400 Kingston; HDD:3x500GB WestrnDigital Caviar Green; VGA: Sparkle GeForce 9400GT 512MB.
I have downloaded an AVCHD file .MTS 1920x1080p 25p, made by Canon HF100 AVCHD camcorder, from this source (.rar file):
http://www.megaupload.com/?d=RWR5MNYHhttp://www.megaupload.com/?d=B9ZDX2RZ
The videos in question called: "25pf_1.25_f1.8.MTS" playback and export from Premiere as MPEG2-DVD very well.
I playbacked it on Premiere on the second Monitor as "OutputDevice". All Ok.
I playbacked also the DVD made with EncoreCS4, on the external DVD set-top-box-player. All OK.
I downloaded also another clip 1080p 25p, converted as .mp4, from the same author, imported then in Premiere with Preset "XDCAM EX 1080p 25p" (470MB) :
http://www.megaupload.com/?d=B9ZDX2RZ
No problems with playback.
Exported as MPEG2-DVD PAL "Lower Field First".
Opened in NeroShowTime Player: the video have a serious interruptions of the playback, some moments plays back-and-forward, and it isn't fluid at all!
I tried to create a DVD with EncoreCS4 and played it with DVD Player set-top-box, and the result is bad, and is the same as the playback on my PC with NeroShowTime Player. It present the back-and-forwars interruptions.
I tried also to create an AVCHD Project 1080p 25p and import the .MP4 file, but the problem persists !
After exporting them, and played-back on NeroShowTime and on Set-Top-Box Player, the video have strange behavior, and plays back-and-forward!
1) What Preset in Premiere should I use to editing, for this .MP4 file format, (filmed with Canon HF100 AVCHD and converted from original .MTS format to .MP4 format)?
2) Is this a transcoding problem?
3) Is this an exporting MPEG2-DVD PAL field-order issue?
This is my bad exported MPEG2-DVD converted file, available for downloading:
http://rapidshare.com/files/337858976/Canon_HF100_1920x1080p_25p_01_AVCHD25p.m2v.html
Strange! With .MTS files I haven't any exporting problems at all!
Please response me hurry!
Many Thanks!
Horsepower.

OK! Sanyo use a bad format.
But about JVC GY-HM100 Professional:
I know this model very well!
It records to .MP4 XDCAM_EX at the same manner of Professionals Sony Camcorder such this: Sony XDCAM_EX model "PMW-EX1" price €6.478,80.
This JVC GY-HM100 camcorder is not tha same as Consumer JVC camcorders.
It doesn't record MOD or TOD files.
It records .MP4 files editables in Premiere with XDCAM_EX "Preset"!
See those details:

The first Brochure called "A Guide to the Most Efficient Workflow with ProHD
(6 pg brochure)" explain very well the .MP4 - XDCAM_EX format and the Editing process that should be with Adobe PremiereProCS4.
I have inspected the downloaded .mp4 file in question, and GSPOT v.2.70a reading this:

1c) Is this an AVCHD video codec?

Importing .mp4 files leads to no playback

Hey everyone, thanks in advance for helping me out.
I recently compressed some large (15GB) .mov files into smaller (500 MB) .mp4 files. Then I moved them into FCP, and now they won't playback at all. I can't play the clips back in the viewer for some reason.
Any advice?

I only tried compressing them to .mp4 with the hopes that smaller files would = quicker rendering.
Why on earth would you think that? This is like saying, I dehydrated my carrots because I thought it would equal quicker eating. Compression (like dehydration) removes mass (and throws away useable stuff). It is designed to pack material in such a way that it is easily transported. But, to use it, the file must be decompressed (rehydrated) into a playable format. This is why all the formats are called CODECS (COmpression/DECompression algorithms).
Some codecs do not screw around much with the material, sort of like simply putting your carrots in the refrigerator. They leave the material in an easily manipulatable format. Other codecs (like mp4) heavily alter the material (more like running the carrot through a juicer). You can play it back easily because the software decoders for playback are efficient, but you can't cook with it. To reconstitute it takes lots of CPU cycles and your computer isn't happy spending CPU cycles on such a mundane task. It wants to do important stuff.
Clear as mud, eh?

QT playback of h.264 mp4 files

OK, I have spent the last two weeks making mp4 files of my TV DVDs to watch at school. Now, my PC won't play the videos properly. The playback is jittery, with the video skipping and the audio matching it. I play the same file through VLC media player or QT on my mac, it plays perfect. Anyone know how to fix it?

this fix worked for me.Right-click the program icon on desk-top and choose run-as, then uncheck protect my computer from unauthorized program activity. I am not sure if this stays that way after a log-out, because every time I check it, it is checked again. I just do it every time before starting the program. Good Luck!

Why does Captivate 6 create mp4 files that the swf does not playback clearly?

Captivate 5 created a .swf which suited my training purposes very nicely. There were swf files in the library, embedded in the (rather large) .swf that I asked the students to run. Now it seems that Captivate 6.0.1.240 won't do that. Captivate 6 creates external mp4 files for the video portion (audio is separately recorded mp3 that is imported to the finished demo video slide) and they look terrible when the .swf runs them. Those mp4 look fine on their own but the .swf must resize them to properly fit with the TOC on the screen.
The HTML created when I make the .swf looks fine but it does not all fit on the screen as does the .swf so I don't like it and don't want to use it. Thanks, in advance, for any replies and suggestions.

Hi llstewart,
I assume you are launching your program from C drive. Are any
components of Captivate stored on the remote drive? (I am thing
your user profile, are you the only person who accesses Captivate
from that machine?)
Does this happen all the time?
What I have noticed in my own network is that there are
periodic "dropped" connections on the network. I have never figured
out what it causing this, but Captivate does not like it. (Every
once in awhile if Word or Excel are writing to a file on a share,
they will become thoroughly corrupted too.)
The problem with Captivate is that it needs a lot of a
computer's resources and takes what it can get. It also seems to
write to a temp file a lot (while a capture is taking place) an
only "binds" it up when the user stops and ends the session. The
only thing I can think of is that during this process there is a
inturruption in your network.
Sorry I couldn't fully answer your question.
I would try (if you can) loading the software on a machine
that is not on the network and try to do a series of long captures
and see if the problem persists.
I work in a large network and I do not have the problem, but
I have also installed the software myself and made sure of the
installation. I also make sure the program I am recording is local
(whenever possible). Additionally, do you have problems with any
other programs and corrupted files?
Again, sorry I don't have a quick answer.

Quicktime playback distortion on some mp4 files

I am having a problem playing some mp4 files through Quicktime. When the video is played in Quicktime (or Pro Presenter 4), portions of the video turn into distorted white blocks that move with the video. It doesn't continue throughout the whole video, but I can't discern when or why it only affects certain portions. It does it every time at those places in the video. I downloaded VLC, and the same exact file plays perfectly fine in VLC and on other computers through various programs. I have only seen this problem on this computer.
Is this a codec issue? How do I fix it?
The files in question are mp4 files using h.264 video and AAC audio at 1920x1080 resolution. I can play other mp4s using h.264 and AAC without any problems.
I have only had this problem with one of the companies that we periodically hire to produce videos for us. I'm guessing that it has something to do with the way he encoded the video, but I have no idea what the problem is. It's probably not his fault if it only distorts on this one computer.
Here is what the white block distortion looks like:
Any ideas?

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode).
Hopefully you still have AppleCare on it.

After IOS 4.1 update, some of my user generated MP4 files no longer play.

You can see them correctly in the play menu in home sharing, and you can fast forward through the file, but they won't play.
The same files worked flawlessly in IOS 4.0 and now they are broken. It's not all files, only some. I have a case opened on this with Apple Care and the response so far from Engineering is: "they only support Apple generated content".
Does anyone have any more insight in to what perhaps was "fixed" that might have caused this degradation (or lack thereof!) in playback of certain MP4s?
Is anyone else experiencing file playback issues with any of their MP4's?

Yup. This is a known issue but it's not known to that many since most of the customers get all their content straight from iTunes. There's only ONE way to get the non-iTunes HD MP4s to play. When you are staring at the blank screen, waiting for the video to buffer (which for the majority of the time, will never happen), press Down on the controller to pull up the timeline with chapter marks. Now, press Forward to skip chapters. With the original 4.1 update, you can skip all the way to the end of the last chapter, give it a few seconds, and then skip all the way back to the beginning of the first chapter (same chapter timeline, but you press Back until it goes to the start of the first chapter). With the recent 4.1.1 update, it's a little trickier. When you skip all the way to the end of the last chapter, if you don't immediately skip back, it will take you back to your videos list because it registers as you having finished watching the video. Now, keep in mind all of this takes places on the timeline with the CHAPTER MARKS.
Second thing, be sure you have chapter marks set on the MP4 file or else the chapter skip workaround will not work (since there's no chapters). You can most probably use any metadata utility you wish to set the chapter marks but I personally am using iSubtitler. I also set the chapter marks for every 10 minutes.
I don't know exactly what has changed since the original 4.0 firmware on the ATV but it has messed up the buffering for large HD non-iTunes purchased videos.

Problem with Premiere Elements 11 uploading mp4 files

I tried to upload a video footage for editing. The video was taken using a GoPro camera and the output is mP4. The footage playback on Premiere Elements 11 was choppy and stalled often. I asked someone else with the same program and he experienced the same issue- so much so that he quit using Adobe's software and switched to Mac/iMovie. Any thought on why or how to fix the problem? I emailed Adobe support a couple of times for the problems encountered in both Premiere and Photoshop but have gotten no response from them. Thanks.

Gumbie10
Appreciated the follow up. Would like to offer some considerations....
1. If you are looking at choppy video, then you must be on the Premiere Elements 11 Expert Timeline or Quick Filmstrip in order to see the choppy video in the Edit Mode monitor. Consequently, to see the video you had to import it.
a. How did you import it? Add Media/Files and Folders to get the files into Project Assets from where you dragged the files to the Expert Timeline. (In the Quick Filmstrip route, there is no Project Assets intermediary. It is Add Media/Files and Folder/with direct to one of the scenes in the Filmstrip).
b. Once you had the files on the Expert Timeline or Quick Filmstrip, did you render the files there by hitting the Render button or by hitting the Enter key of the computer main keyboard?
2. Premiere Elements 11 automatically takes over setting up the project preset for a new project. The project preset should match the properties of the source media. Sometimes it does the set OK; sometimes, not. Check to see what the program has set if you did not set the project preset yourself manually. (Edit Menu/Project Settings/General and readings for Editing Mode, Timebase, and Frame Size.)
3. If you are using the GoPro Hero 3 Black at the 1080p set, then the video codec (compression) is AVCHD (MPEG4 AVC/.H264). The question becomes at what frame rate...30, 60, or other progressive frames per second. From what you wrote, apparently what you have has a .mp4 file extension (that is what is called the container, the format that wraps the video and audio compressions).
4. Then we come to the matter of your photos. What are the pixel dimensions that you are trying to use for this Premiere Elements project? Have you gotten to importing the photos or is it only the videos that you have tried to import into a Premiere Elements 11 project?
Please review the above.
But, I am also concerned about
Meantime, for still images, I did my editing on PS Element 11 and used Live Movie Maker to put together the video. It works for me. I had trouble with the output (to burn DVD/Cd and to upload to PS showcase) in the PS Element as well.
Thanks again for the input. I'll give an update later.
Do you want two separate projects, one for video and one for stills or is all that a workaround for overall issues.?
Please do not hesitate to ask for clarification on anything that I have written. I will rewrite if necessary so that we are in sync.
The answers are in the details.
More later.

Will iTunes or QuickTime Player let you burn an mp4 file onto an audio CD?

I want to burn some MP4 videos (i.e., the audio portion only) onto audio CDs; I guess that would mean converting to .aiff files, right?
Can this be done in either iTunes 10.6.1 or QuickTime Player 10.0? I'm running Mac OS 10.6.8 on a Mac mini, if that makes any difference.
Or do I have to find some third party software to do the conversion and then burn the CDs?
Thanks in advance for any advice you can offer.

I want to burn some MP4 videos (i.e., the audio portion only) onto audio CDs; I guess that would mean converting to .aiff files, right?
Depends on how you plan to play them back. AIFF can be played on almost any commercial audio CD player. MP3 files can be played on most current CD players. Apple Lossless or AAC could be used if playback is through your computer. The choice is really yours.
Can this be done in either iTunes 10.6.1 or QuickTime Player 10.0? I'm running Mac OS 10.6.8 on a Mac mini, if that makes any difference.
Yes, but the work flow may be different depending on which software and audio compression format you use. E.G., QT 7 Pro could extract the MP4's AAC audio track directly to an new file without conversion if AAC is your target format. As previously mentioned, QT X could be use to recompress the MP4 to an audio only AAC file. The free MPEG Streamclip or QT 7 Pro apps could be used to convert the MP4's AAC directly AIFF files. Converted or extracted AAC files could be added to your iTunes library where iTunes could create and burn a "Playlist" of such files to CD using AAC, AIFF, Apple Lossless, MP3, or WAV compression formats dependin on your playback requirements. (Unfortunately, iTunes will not directly extract and reprocess/burn the AAC audio directly from MP4 files already in its library.

Hi apple users, I am in need of your expertise. I have a mov file and mp4 file which I need converted to DVD. However IDVD quality is terrible and wondering if anyone can help!?

I created project in iMovie then exported it to MP4 and also MOV file at highest definition possible + I added it to iDVD and had a number issues about encoding errors regarding the mp4 file. MOV worked but the quality was terrible.....
MOV file is as follows:

I have a MacBook Pro using the Yosemite system upgrade.
I have updated iDVD and iMovie.
I even bought the iSkysoft app from the mac store and that was terrible too.
PLEASE HELP i am getting desperate and about to launch this macbook into the air
2.66 GHz Intel Core i7
Version 10.10. 2

First of all, Hunt--thanks for responding!
"First, where are you playing the MPEG-2, that you see that jitter?"
On both a MacBook Pro, an Acer laptop and my Mac Tower. I would love to think that it is a problem with the playback system, and that if I merely send the file off to the duplicator they won't have the same problem. Maybe that is the case...I don't know if I have a choice rather than sending it off to see. But it happens in the same spots, in the same way, on all three of the players so I'm a little reluctant to have faith.
"Another thing that can cause jitter in an MPEG-2 is the Bit-Rate - higher the Bit-Rate, the better the quality, but the larger the file. For a DVD, one is limited by the total Bit-Rate (both Audio & Video), but with longer prodcutions, some users choose too low a Bit-Rate. If this is the issue, one would need to go back to the original Project and do a new Export/Share."
Of course, but in the case there is no more 'original project.' It is gone like the wind, stolen along with his computer and backups.
I think I am stuck using one of two files as my master: a DVD he burned where I only see the stutter/vibration/jitter once, or the mpeg2 file where I see it three times. Hopefully, the duplication house can rip if off of one of them and not see the jitter. I know that in audio, my personal filed, you can do a lot to enhance already existing sound--EQ, compression, tape saturation emulation software, etc. I guess I'm hoping there is some kind of analog to the video world that address jitter after a source has been printed--if indeed the source has been printed to be jittery.
Thanks,
Doug
