Here we recommend two softwares, both of which are relatively small in size:
PacketVideo PVAuthor (to MP4 and 3GP) and EO Video (from other formats such as ASF RM to AVI).
I won't talk about EO video, the usage is simple and there is a Chinese version.
Usage of PVAuthor:
After opening, select a file and an encoding file. The most important thing is the coding tab. We choose the highest 128000bps. Special note: Then click the label below, switch to the codec page, and select AAC 32K, 22KHZ, stereo (unless you want to listen to mono).
The bandwidth in the parameter is set to 128 and the animation is set to 64.
After the video size, the encoding setting parameter MAX FRAME indicates the number of frames, and the animation uses 6.25.
Real people use 12.50, and larger frames may not play smoothly because of caching. Therefore, 12 is recommended.
Then you can output it. This software needs some basic English.
I will upload tools and software in the future.
Then select the codec settings tab. These settings basically depend on personal preferences. The maximum frame rate is preferably 15fps.
After completing the above settings, don't forget to click the Save Profile button to save these settings, so you don't have to reset them next time.
Finally, click the OUTPUT TAB above to set the output file name, and then click OK and start to start coding. Coding speed is faster than mpegable.
How to make MP4 format movies?
How to use IC2
After opening the image converter software.
Select a file, select the folder where the file is located on the left, and display the files that can be converted into MP4 on the right.
Then choose the frequency of the video. After selecting the video, connect the PSP to the computer and select MSD to start the transmission.
After the transmission, unplug the USB cable from the PSP to the computer, and you can watch the MP4 video just transmitted in the PSP.
If you switch to rm, change the file suffix to AVI or wmv. If not, please download the latest decoder.
If the MP4 file is transferred to the local disk, then pull the whole file "MP_ROOT" to the root directory of the mobile disk and put it in the PSP folder, so it can't be played. Remember not to put it in the wrong place
Parameter settings should be modified in the registry HKEY _ Local _ Machine \ Software \ Sony Corporation \ Image Converter 2 \ 2. 1
Quality corresponding to prefix: LO/96 NO/92 HI/384 SH/768.
The suffix corresponds to the parameter width/width height/height video /Kbps stereo/channel.
Audio/sound sampling rate (bits) Frame rate/frame
Nokia Multimedia Company.
This is also the software I want to recommend to you.
First, RM is converted into MPG4, previously converted from EO video to AVI, and then converted into MP4. Now with RM converter, RM can be directly converted into MPG4 format file, which is faster than EO video. This software is very simple to use, and how to operate it is actually very simple. You can find that both English and Chinese versions of this software are 1 by searching with a search engine. Version 27. Download Nokia Multimedia again.
When you download and open the software, the top one is to select the source folder, the second is the converted folder, and then click AVI below. ) Then click "Start Conversion" on the right, or you can choose preview when prompted.
Then open Nokia Multimedia to open the file. Everything else is the default. Just click "Conven" to prompt to save the path and enter the file name.
For example, the file in RM format has a size of 6M, and the final format is only 2M to 3PG, and it is particularly clear ~ ~
Because I just put up the written instructions on how to use it now, in case you don't understand, I will post a teaching sticker with pictures in the future.
Most of the generated software is H263, which can be changed. I put it on the PSP and found that there are visible and invisible ones, but the NC software is not much different from the 3GP format, so it is not recommended.
Intra-frame coding technology in H.264 is the same as the previous standard. It is worth noting that the reference macroblock of intra-prediction coding macroblock in H.264 can be an inter-coding macroblock, which is different from that in H.263. However, intra-coding with prediction has better coding efficiency than intra-coding without prediction, but it reduces the resynchronization performance of intra-coding, which can be recovered by setting the limit intra-prediction flag.
