Hi all,

I am new to MTV. What I have is a mp4 player(China made). I got a conversion tool(mp3 tools) with the player using which I can convert video files to MTV. But, the problem is, the device has only 256mb and MTV files are taking a lot of space. I tried to redce the quality, but the audio doesn’t go below 64 kbps, I tool doesn’t support it. how can I go around this, I would like to have movie length videos though quality is not of prime ?

help me out guys,
Amar reply

@Amar

The filesize can be estimated like this:
estimated_filesize = header_size + (seconds * fps * (img_size + (audio_bitrate * 128 / fps)))

Therefore the filesize does not only depend on the audio bitrate and the duration (seconds) of the video, but also on the size of the image and the frames per second.

Because the size of the image is fixed to the specifications of your display hardware, the only additional parameter are the fps.

The estimated filesize for one minute of mtv video in dependency to fps and audio bitrate are as follows:

fps 64 kbps 128 kbps
1 1.229.312 1.720.832
2 1.966.592 2.458.112
3 2.703.872 3.195.392
4 3.441.152 3.932.672
5 4.178.432 4.669.952
6 4.915.712 5.407.232
7 5.652.992 6.144.512
8 6.390.272 6.881.792
9 7.127.552 7.619.072
10 7.864.832 8.356.352
11 8.602.112 9.093.632
12 9.339.392 9.830.912
13 10.076.672 10.568.192
14 10.813.952 11.305.472
15 11.551.232 12.042.752
16 12.288.512 12.780.032

As you can see at the very first look: the audio bitrate has almost no effect on the filesize but the fps have a tremendous impact.

Therefore my recommendation is to lower the framerate as much as necessary to achieve a filesize small enough to fit on the player device.

Hope that helps.

supplemental:
header_size is always 512 byte
image_size for 96*64 pixels with 16bit color is 96*64*2 -> 12288 byte reply

Thanks Stefan,

I tried that, going below 8fps is resulting in jerky video. And moreover, this size is over 6 mb for one minute(as you have estimated), which means I cannot store more than 40 minutes of video!

Stefan, if you have any idea of those china made mp4 players, what all video formats does the device support ? It tried WMV, but the device plays only audio stream and not the video. mpg is not recognized. I don’t want to try MTV, as it taks lot of memory.

You, basically understand my problem right ? I need to store a about 120+ minute video on the device with 256 Mb (lol). What can be done about this ?

p.s.: Is there a way to increase the memory of the device to 1Gb? if yes, can you pass on the details like(the which flash chip, how to...).

Thanks,

> ...what all video formats does the device support ?

The most so called china mp4 devices I’m aware of, support only variations of mtv like dmv or mpx. There is no chance at all to play native wmv or mpg without prior conversion because those devices have neither hardware nor software decoding support. The concept of the mtv format (and all derivates) is, to have an mp3 stream that carries image information that is allready in the format of the display hardware (uncompressed). A hardware mp3 decoder is already in place, the display hardware only need to point to the memory adress of the next image (simple implementation in soft- and hardware).

> I don’t want to try MTV, as it taks lot of memory

I’m afraid that there is no joice at all

> I need to store a about 120+ minute video on the device with 256 Mb

Forget it, no chance at all.
You can have a 120+ minute video on such a device in mtv format in reasonable quality if the device has at least 1+ GB of memory.

> Is there a way to increase the memory of the device to 1Gb?

I wouldnt mess around with the hardware. Even if you find a memory chip of the necessary physical dimensions you will have no garantee that the firmware will be able to address the additional memory as it was designed for a fixed amount of memory. Not to mention the problems with the pin-layout and the difficulties of soldering tiny SMD-parts.

Hope that helps.

I’m interested of adquiring that software that transforms to .DMV :). I read all the topic but found no link. :( reply

@Stefan

Thanks Stefan, bullsye, u hit the point straight.

I now understand that the player with 256MB is not even worth to throw in to trash(lol).

Next time, I won’t look to anything less than 1GB.

p.s: where can I get a firmware updrade ?

Thanks,

@Amar

I wouldnt say that it is not even worth to throw in to trash as it is certainly still a nice audio device (with sufficient memory for that particular purpose).

I have not yet tried to upgrade the firmware and according to what I have heared, one shouldnt do so as long as there is no urgent need to do so.

The upgrade of the wrong firmware can make your device unusable. And if so, and you cant recover the original firmware, your player will be lost forever.

So if you decide to upgrade, make absolutely sure that you have the right firmware.
