I have 3 cameras but go sot sick of having 3 long tracks that I bought that remote control. When it works....repeat...when the GoPro smart remote works the audio has always been aligned on all 3. For me I don't care if I miss some ATC stuff when they are not running. But the advantage is that they have enough battery for a 2 or 3 hours flight. Since we are asided on editing I think my latest flow has been like this:
1. Create a new sequence and add all the clips from the first gopro back to back. Do the same for the other 2 cameras for a total of 3 sequences.
Time:
+5 minutes (easy)
2. Create a new sequence from each of the above and make all the video effects changes (bring up shadows, sharpen, contrast). Since they are different angles they need slightly different corrections.
Time:
+30 minutes (pretty easy, hint - presets help!)
3. Go to the track that was connected to the intercom/ATC and duplicate the left channel onto the right so all the talk is one both channels. Set its gain to about 85%
Time:
+3 minutes (easy...once you know where it is, just uncheck 1 box and check another)
4. Pick one of the other 2 sequences and adjust its audio to about 10% so you get just a bit of the engine noise (if wanted)
Time:
+3 minutes (very easy)
5. Create a new multi-sequence sequence by selecting all 3 of the edited sequences.
Time:
+5 minutes (its confusing the first time or two on what to select and what it makes)
6. Now its time to pick what camera view. You enable the multi-sequence viewing option and open that multi-sequence thing you just made. At this point you watch the video from beginning to end and select what camera angle you want as you watch it. It will create/update a new sequence as you go. You can leave this part-way through and come back later. As you watch it you will be hearing all the sound correctly. This is perhaps one of the most time consuming parts.
Time:
+90...120minutes (for 20 minutes of raw footage)
7.) Okay, now its playing pretty nicely but you have edit out audio for swear words and just generally sounding like a dork or saying bad things about your instructor LOL! For this step you go back to the 3 sequences you made and lock each one's video track (so you can't wreck it). Then find the spot you want gone and literally cut that audio out (I think that is easier than lowering the levels). This part is more time consuming as it can take a while to find each part. But then again the early step of not recording the entire flight cut down quite significantly on how many need fixing.
Time:
+60 minutes
8.) Now you can watch it thru and see if you cut some audio while the camera was looking at you...bad!!! So you need to tweak the multi-sequence view again (easy) to get to another camera angle.
Time:
+30minutes
9.) At this point you can also start cutting down the entire thing. Remember, you could have cut the entire thing earlier but I think its better to have and see all the footage this way and then make fial edits for length.
Time:
+60 minutes (this takes time)
10.) Adding any extra audio. Actually, going to one of the sites (I used Epidemic) takes a lot of time, like a ****load of time. I see Radar Contact uses the same track and over and over that saves all that time.
Time:
+30...60 minutes
11. Adding very simple titles. If you don't get to carried away and know how to create titles and fades this step is pretty quick
Time:
+20minutes
12. Rendering. The most important part is to know which preset to use. If you are uploading 4K it will take longer. Its nice to render at maximum quality and maximum bit depth. And maybe set the encoding just a few megabit higher than they specify. The real key here is to have a GPU. My crappy old 1st generation I7 used to render to slow. A couple years later I bought an new video card and it has a GPU. Now the rendering is very fast. My time to render about
6 minutes of video:
Time:
+15 minutes (about 2.5x that for 4k)
...so for a simple, linear 3 camera edit (closer to what
@Radar Contact is doing) I use between 6...7 hours. Using the steps above its easy to break it into 2 or 3 sessions. That is around 1hr per minute. But that is not including different scenes, different cuts, clips in different order, graphics, etc like
@SixPapaCharlie and
@write-stuff are doing. I can easily see those hitting the 10hrs/minute rate or even higher.
ps. Wives think it takes the same amount of time to edit a video as watch it
