I have a tough time using PSP and YouTube downloader, for the FLV video files I download do not compatible with PSP player, which supports only MPEG4-AVC/H.264. At first, I try to convert these FLV videos to general MP4 video, but the output files fail to play on my PSP. A friend told me that I need a converter to change these files from FLV to MPEG4-AVC and he recommended one called Aneesoft Video Converter Pro he used himself. I download its trail version and tried it myself.

Things you’ll need
1. Aneesoft Video Converter Pro (Free for download trial version)
2. FLV video files
Step 1: Download & install Aneesoft Video Converter Pro
We’ll be using the very nice video converter software called Aneesoft Video Converter Pro for converting FLV videos to MPEG-4 format for playback on iPod, head over here and download the free trial version. Next step is to install the program.
Step 2: Run Video Converter Pro and add FLV video files
Now run Aneesoft Video Converter Pro and click the big button "Add..." to add FLV video files on your computer, you may add as many videos as you want to convert to videos. Only the titles you checked will be converted. So if there're some videos you don't want to convert, you need to uncheck them or 'Remove' them from the right-click menu. 'Clear' in the right-click menu means remove all titles in the list.

Step 3: Edit videos: crop, trim, add effects, add watermark
Wanna edit your videos to make it more personalized? You may add a watermark in Aneesoft Video Converter Pro. Just select the title you'd like to add watermark, then click the button 'Edit' to launch video editing window. If you want to crop video or add some special effects, click the first two tabs. You're able to add a text watermark or an image watermark (you may call it logo) on the output video. Adjust the 'Transparency' to make the watermark look better.

Step 4: Merge some separate FLV videos to 1 MPEG-4 file
Click on the video titles you'd like to merge to 1 single file, then click 'Merge' button and uncheck the former separate files if you just need the single merged video file. Here 'click on the video titles' is not just check the options, you need to click them to make them highlight. You may see the image below to have an idea.

Step 5: Change the output settings to convert videos with best quality
Choose the most suitable MPEG-4 output format as you want. Besides to MPEG-4 format, there are almost all common video formats available for you to choose to convert. You may convert FLV videos to different video formats for video editing or playback on your mobile devices, such as iPhone, PSP, cellphone, etc. Remember that the output file size mostly depends on the Bitrate you set. Larger Bitrate, larger file size. Actually video with bitrate as 768 is acceptable for watching.

Step 6: Start converting FLV videos to MPEG-4 videos
Now you may click the big button "Start" to begin converting FLV videos to PSP MPEG-4 videos. Once the convert is complete, Aneesoft Video Converter Pro will place a new version of your video. Double-click the new PSP MPEG-4 file and play it to make sure it looks as you expect.
