Cannot open MP4 file?

Post by free3free »

When I open MP4 file in MF4, it pops up a dialog box
"File Format Mismatch [16803:1:].

However, the MP4 file can be played in all players (Windows Media Player, Divx Player & etc) once I installed 3ivx filter. I don't know why it cannot be opened in MF4. Any settings needed?

BTW, the MP4 file is captured from Sanyo digital movie camera.

When I used MP3 bundled with the Sanyo camera before, I was able to open MP4 file... why MF4 cannot?

Can anyone help?

this is because your DMF3se is specially designed to support such file format. Bundled software usually supports the devices they are bundled to. I suggest you create DVD folder in DMF3 using your MP4 videos then import the DVD-folders in DMF4.

I originally presume that DMF4 is able to read whatever format as long as appropiate codec is supplied....

BTW, does it mean that MP4 generated by Sanyo digital movie camera is NOT standard ? I mean it is not a standard MPEG-4 file? My thinking is DMF4 should be able to read this common standard format, which becomes very popular in the net and devices. Any comment ?

im not sure about the specs of MP4 videos. All i know is that there several codecs that you can use for MP4. As for DMF4, check the system requirements for the file input formats supported.

i think VideoStudio 9 (with additional) plugin supports MP4 formats. im not sure if they will ever release a mp4 plugin support for DMF4.

who knows...

I've run into the same problem. But there is a work around.
I have the Sanyo HD camera also. Before I installed the bundled DMF4 SE software, I had to remove my full DMF4 install. That sucks because the full version has some extra stuff that the SE doesn't have.

I found that the bundled DMF4 software happily imported the MP4 files, then screwed up the DVD output by setting the aspect ratio to 4:3 no matter what I did (including editing the IFO file). That sucks.

So I figured upgrading to DMF5 would fix everything. Wrong. DMF5 doesn't like MP4 files either.

I found that TMPGenc would encode to MPEG2 DVD using MP4 files, so....

I removed the DMF4 SE and re-installed the DMF4 full program.

TMPGenc stopped working with MP4 files. So....

I installed Photo Explorer that came bundled with the camera. Great, TMPGenc likes MP4 again, and I have DMF4 full working.

Note: The Sanyo HD camera makes a new MP4 file every time you hit the record button. If you like to take a lot of 10 second shots, then you get a lot of files. This would be OK, except that Movie Factory won't combine them as one smooth clip. After authoring, every clip freezes at the last frame for a second or two, then there's a black screen for a second, and then the next clip starts. I don't remember this being a problem in the past, but I've seen people talking about it in posts lately.

Anyway, this frame freeze makes using the DMF4 SE not appealing. I suppose I could go look on my hard drive for the converted (MPEG2) files and combine those in TMPGenc to make smooth clips. But then I'm stuck with SE and not my full software.

Here is my work around until Sanyo or Ulead wakes up: Batch encode using TMPGenc. Make a DVD template that that changes the resolution to 720x480, 16x9 aspect, 29.97 fps, constant quality 8000-2000;80 quality , non-interlace, 10 bit precison. In the source, I have to keep changing it to non-interlace and 16x9 aspect for every clip addition to the batch list. (I don't know why it's seeing the clips as interlaced, since they are progressive).

Then I use TMPGenc tools to combine all the resulting clips into one; then import to DMF to author and burn. The results are outstanding. The time it takes sucks. The software shortcomings are going to make this camera a non-buy for the average consumer.

UPDATE:

Try this program at this link:
http://www.erightsoft.com/SUPER.html

It's called SUPER and it's mainly for converting DVD movies to pocket PCs, etc. But it works with Sanyo MP4 HD files. Drop the clip(s) in and pick MPEG2 DVD specs or leave it at the same HD resolution. Make sure the settings are all high quality (8000kbs, etc), as it defaults to low quality. Fast and the output looks, well, pretty good.

An HD MP4 file converted to an HD MPEG2 file imported to the HD-DVD part of DMF5 and it started converting. Probably works.

I dropped the DVD conversion into DMF5 (with Dolby Digital) and it just took it without rendering. Now I need to see if the quality is good enough to use on my 50" plasma. I will if it's close to the previous procedure.

Another update: I had to turn off the "stay on top" feature of the program to make the menus show up-- they were transparent until I did this. Also, you need to check the "high quality" and "stretch" boxes to the right to make the video 16x9.

Another update: I authored a DVD in DMF5 using the resulting output from SUPER (it uses ffmpeg or mencoder). Quality is excellent, considering it was a school basketball game. (My earlier attempts at bball games using a DV camera are blurred and washed out compared to this new DVD authored from HD.)

The TMPGenc encoded version was no better, so I'm dropping that unless I need to do color correction, etc. Next on the list is to confirm that SUPER will join the resulting mpeg2 clips as it says it will do.

Update: SUPER joins files nicely, if not intuitatively. Mencoder does not work with MPEG2, so ffmpeg is only option for making HD MPEG2 files.

Mencoder did work with VOB as container file, resulting files look much better than ffmpeg output; probably because ffmpeg seems to throttle the bit rate too low compared to mencoder for the same set bitrate. Maybe just raising the bit rate would improve it. (later I found this not to be true, it looks worse no matter what) VOB file imported to DMF5 OK.

UPDATE: My other computer (Gateway) didn't like the output of the mencoder; sound distorts at beginning and ending of clips, and video plays distorted in media player classic. However, once authored in DMF5, everything is beautiful. Had to output mp2 sound and use TMPGenc to join files, because SUPER didn't combine video with sound. DMF5 then just converted MP2 to AC3.
