camtasia 3 rendering poor quality export

This seems to happen when the screen changes from a dark background to a light background. This does not happen with the Camtasia video. In the Resolve video at the 2:37, 6:18 and 8:09 marks there are black video artifacts that flicker on the screen. If you open both videos side by side and look closely at the small text in the top left, the Camtasia rendering is noticeably sharper during playback (even if you pause the frame). Let's first talk about the poor video render quality: The Camtasia file is nearly twice as small, but it's superior looking during playback and has zero 'show stopping' video and audio artifacts where as the Resolve video has many issues. When it was set to high the video was MUCH larger than it already was, didn't look any better than Camtasia's video and it still had both the video and audio artifacts that we're about to go over below. You can verify these rendered video stats by downloading them and looking at the details of the file.įor Resolve's mp4 x264 settings, I am using the default values for everything except I changed the quality to be 'low'. The Resolve rendered video is 100mb with 1444kbps data rate and 1598kbps bitrate with 48k audio at 153kbps. The Camtasia rendered video is 58.9mb with a 809kbps data rate and 935kbps bitrate with 44.1k audio at 125kbps. In both cases I used the same OBS source mp4 which was really an x264 mkv file that was remuxed to mp4 with OBS using a 2500 kbps bitrate and 48k audio at 160kbps. I recommend downloading the files locally so network compression isn't taken into account and to also check out the details of the video to get the bitrates. One of them is rendered with Camtasia's default settings and the other is rendered with Resolve. This just happens to be the latest tech related video I recorded.

Since talk is cheap, I've uploaded (2) ~8 minute mp4 videos to DropBox. I also want to preface this by saying that both the video and audio quality issues aren't apparent in Resolve's time line playback so this must be related to rendering the video in some way or another. The problems I'd like to discuss in this thread are related to poor mp4 render quality with both video and audio artifacts along with producing large file sizes when compared to other tools.
