Flash Remover plugin<\/a>.<\/p>\nI downloaded trial version of the plugin and tested it. Well, I wasn’t satisfied with the results.<\/p>\n
First, the plugin simply duplicates the last good frame a few times. It’s OK when the photo flash occurred in one video frame only. In this case two equal frames in a row exist in resulting video. In case of two-frames flashes it will be three equal frames in a row that is very noticeable.<\/p>\n
Second, after applying the plugin to a fragment\/track you have to guess the correct threshold value. The ‘Normal’ value in my case can’t find all flashes.<\/p>\n
Third, after applying the plugin, sometimes you will see the flashes on the preview anyway (in the final render all would be fine). As a result, you can’t be sure that all flashes are removed with chosen threshold value. You will need to re-render it just to check.<\/p>\n
Finally, you have to pay $100 for the whole NewBlue Video Essentials plugin pack even if you need this plugin only.<\/p>\n
As a result, I’ve tried to find a solution to remove photo flashes from my videos without additional plugins.<\/p>\n
The simplest way to remove flashes \u2013 duplicate frames.<\/p>\n
If in a single-frame flash frame 2 is damaged, you must duplicate frame 1 or frame 3 and put it just over frame 2. Easy peasy. On resulting video you will have sequence 1 1 3 (or 1 3 3). In case of two-frames flashes you have to duplicate frame 1 and<\/b> frame 4 and put them over frames 2 and 3. On resulting video you’ll have sequence 1 1 4 4.<\/p>\n
More advanced way to remove flashes \u2013 resample.<\/p>\n
For a single-frame flashes copy frame 1 and frame 3 on a new video track and put them together. Frame 1 must be over source frame 1 and frame 3 must be over source frame 2. Make a selection with two these frames and press Ctrl+M (Render to New Track). Choose codec (I’m using lossless MagicYUV, UTVideo or Cineform encoders), filename and location for a new two-frames fragment and render it. Now press Ctrl key, take the right edge of the new video fragment and stretch two-frames fragment into three-frames fragment. Vegas will leave the first and the last frames untouched and will resample the second frame. Finally, the first frame of the fragment must be over the first source frame. Done.<\/p>\n
For two-frames flashes it will be a bit more complicated. Create a new video track above and copy frame 1 just over frame 1. Copy frame 4 and put it over frame 2. Make a selection with these 2 frames and render it as a new fragment on a new video track (Ctrl+M). Now press Ctrl, take the right edge of the new video fragment and stretch two-frames fragment into five<\/b>-frames fragment. Now cut the last frame of this five-frames fragment (release Ctrl key, take right edge of the fragment and move one frame to the left). Now move the fragment on its position \u2013 the first frame of the fragment must be over the first source frame. Done.<\/p>\n
