Openworld FlashPresenter - Video Converter

How to Convert Your Video Into a Supported Format:

FLV Video Encoder, used in The Openworld FlashPresenter supports only few basic video compression formats for source video. Such are MPEG-I, MPEG-II, DiVX Low Motion MPEG-4 formats. So, you can't use it directly if your video is recorded in some more advanced video formats like Windows Media 9 (a.k.a. WMV3) format and some other.

The main purpose of this tool is to convert your source video into supported video compression format without extra quality losses. You can choose appropriate video / audio codecs using the Video Encoding Preferences page. Then you can use Video Converter tool to convert your video into a supported format.

How Video Converter works:

All you need to do to start conversion process is to assign the source and target file names and choose encoding parameters by adjusting video codec properties. You can see usual video codec properties page here. It will depend on the codec chosen, how this page will look, but in any case you can find two meaningful options there:

Key Frame Interval It affects to the target file size. The higher is the value the less is the file size if there are no fast motion scenes in the movie. On the other hand high values, set here, may lead to inaccurate navigation in the resulting (streaming FLV) video, after you'll use the converted video in the FLV Video Encoder. So, it is recommended do not set values, higher than 1 sec. here, what gives one key frame per approx 25 frames. Also please note that actual keyframe rate will depend on the target bitrate, set in FLV Video Encoder parameters before encoding. Low bitrates will lead to higher keyframe interval value, but (naturally) will produce video of worse quality.

Target Bitrate defines the bitrate in the converted video. It is not recommended to set low values here. You main goal now is to get video file of supported format. Later (in FLV Video Encoder) you'll can choose the target bitrate for your FLV video and even produce several videos with different bitrates using the same source video file, e.g. to deliver your content to several target audiences.

You can preview the converted video to check its quality and change encoding parameters if you're not satisfied by the quality or target file size.

IMPORTANT NOTICE: XVID Video Codec has a known bug, preventing movie playback in so called "compatibility mode". Therefore please ensure that "Use VMR Mode for Preview" checkbox of the Video Converter is set, when you're using XVID codec. Another resolution of this bug is to open XVID Video Codec Configuration dialog and set the "FOURCC" signature to "DIVX" before encoding. Click "Video Settings" button in the Video Converter window, then click "Other Options" button at the bottom of "XVID Configuration" dialog for that.

Tracks alignment control It affects to the video vs audio track alignment in the case if track durations do not coincide. Some web-cameras create videoclips, where audio is a bit longer than video, which has a small "gap" on beginning. Video track may also be shifted against audio track within video clip by some reason. You can use the tracks alignment control to process such incorrectly written video files. Usually you don't need to change this option, because most of video hardware/software record video/audio tracks in synch.

IMPORTANT! Using free version of the DivX codec you may see a logo, appearing at the bottom right screen corner of the video frame, when you preview encoded video file. This logotype appears on screen only -- it is not embedded into your file. Therefore your final FLV video file will be free from this logotype.
