You need to re-encode your video with the changed bitrate.
Avidemux shows the error message "bitrate too low" when exporting a video file because the bitrate setting for the video is not high enough to maintain the quality of the video during the export process. Increasing the bitrate can help improve the quality of the exported video.
You need to download a Bitrate converter.
The length of a 600 MB video can vary significantly based on the video codec, resolution, and bitrate. For example, a 600 MB video at a standard bitrate of around 5 Mbps may be approximately 10-15 minutes long. However, if the video is encoded at a lower bitrate, it could be longer, while a higher bitrate would result in a shorter duration.
To encode a video with variable bitrate using ffmpeg, you can use the "-b:v" flag followed by the desired bitrate range. For example, you can use the command "ffmpeg -i input.mp4 -c:v libx264 -b:v 1M -maxrate 2M -bufsize 2M output.mp4" to encode a video with a variable bitrate between 1Mbps and 2Mbps.
The optimal bitrate for achieving DVD quality in video playback is typically around 5-9 Mbps.
FASM "Quality Enhancer Bitrate Squeezer" is an application for compressing h264 video streams, optimised for low bitrate.
The amount of video that 256MB can hold depends on the video's bitrate and resolution. For example, standard definition video at a bitrate of about 1,000 kbps can yield approximately 30 minutes of video in 256MB. However, high-definition video at a bitrate of 5,000 kbps may only allow for around 5-10 minutes. Therefore, the duration varies significantly based on the video quality and compression settings.
The amount of video that 8GB can hold when recording in 1080p depends on the bitrate of the video. On average, 1080p video at a bitrate of about 8 Mbps can take up roughly 1GB per 10 minutes of footage. Therefore, with 8GB, you could expect to record approximately 80 minutes of 1080p video, assuming consistent bitrate and no other storage overhead.

The length of a video in minutes cannot be determined solely from its file size (160 MB) without knowing the bitrate (data rate) of the video. For example, if the video has a bitrate of 1,000 kbps (kilobits per second), it would be approximately 21.3 minutes long. However, if the bitrate is higher or lower, the duration would vary accordingly. Thus, the exact length depends on the video's encoding and quality settings.
Bitrate
The amount of video that 4 GB can hold depends on the video quality and compression used. For example, standard definition video at a bitrate of 1,000 kbps can hold approximately 4 hours of video, which is about 240 minutes. In contrast, high-definition video at a bitrate of 5,000 kbps would hold roughly 48 minutes. Therefore, the duration varies significantly based on the video settings.
