Occasionally, when watching a replay and switching POV or to editor mode, you will see disembodied arms floating about (which you can see through walls). Simply clicking "detach" does not fix it. The only solution I know to get rid of the arms is to switch back and forth between POVs while the replay is playing and then detach from the disembodied arm's POV. I'm not quite sure the exact circumstances required to reproduce this but it may be related to keyframes being added in Editing mode while still attached to a player.
Here's a brief guide to Reflex's replay editor. (FULL DISCLOSURE: I am not an expert. If I've explained something inaccurately or poorly, please let me know.) BEFORE YOU BEGIN EDITING 1. Bindings: You can find all the useful Reflex Replay Editor bindings through the menu --> Options --> Bindings. Use the drop down menu to select Replay Editor: 2. Config: Before you start, always take a few moments to make sure you've got your config the way you want it. Graphics settings, FOV, weapon offsets, force enemy colors, frame rate, depth of field, HUD details, etc.! It is extremely frustrating to start a big project, get half way through, and realize there's an issue with the config. So it is worth a little patience to test out your config before you start! 3. Disk Space: If you plan to use Reflex's re_export function, make sure you have enough disk space. Re_export essentially produces an image sequence, individual PNG image files for every frame you export, which you will eventually want to combine into a video file. Think about it this way, if you export 5 seconds at 60fps and each image is 1MB (at 1080p resolution), that's 300MBs for just a 5 second clip. If you're planning to make a movie longer than 5 second, please keep that in mind! USEFUL CONSOLE COMMANDS The Reflex Files wiki page has a useful list of these console commands located here: http://wiki.reflexfiles.com/index.php?title=Category:Replay_Command. Some are out of date (like re_showtimecode is, sadly, no longer a working command), but most should still be active and working. With the addition of the new Replay Editor HUD, many of the console commands do not need to be used. However, there are still some commands that you won't be able to find on the HUD that may be useful to note: re_set_angle: Used to set camera angle rotation. First set your keyframe and then, without moving from the keyframe, use re_set_angle to update the keyframe's camera angle. re_set_fov: Used to set camera field of view. First set your keyframe and then, without moving from the keyframe, use re_set_fov to update the keyframe's camera FOV. re_export_frame_rate: Used to set the number of frames per second exported. r_depth_export_scale: Used to set how far the depth of field image sequence looks. See Nathan's Depth of Field tutorial for more details. LOADING A REPLAY 1. Lower the console with ` (tilde) and type "play <replay file name>" (without the quotations). For example: 2. When you load a replay, you'll notice that the "timeline" is filling up. That means it is loading. You won't be able to drag the timeline further than where the replay has loaded to. For a 10minute replay, it may take 20-30 seconds to fully load. REPLAY EDITOR HUD 1. MODE: This button lets you toggle between the "EDITING" and "WATCHING" mode. EDITING mode is what you use when you want to make a third-person camera which moves (this is explained in more detail in the "CREATING A SIMPLE CAMERA" section). WATCHING mode is when you are either just watching (duh) or when you actually want to EXPORT. 2. SAVE: I believe SAVE lets you save your camera work. So when you reload the replay later, you can still see the camera path and keyframes you've added to the replay. 3. REPLAY CONTROLS: The outer two arrows (double arrows and bar) are for previous/next keyframes, the second and fourth arrows (single arrows with bar) are previous/next frame, and the middle is play (re_speed 1). 4. MARKERS: If a replay has markers, you can scan to these with PREV or NEXT. 5. EDIT KEYFRAMES: When you want to create a third-person camera, these buttons are the key! ADD and DEL are pretty self-evident. You can use UPDATE to change the placement/angle of a keyframe ONLY if you're at the current keyframe in the timeline. 0 ROLL resets the camera roll angle. RESET, I believe, clears your keyframes. 6. PLAYERS: There's a drop down menu that lets you select which POV you want to view. If you're in WATCHING mode, simply select the player's name and then select ATTACH. If you're in EDITING mode, then selecting DETACH will let you move the camera freely around so you can do some camera work. 7. EXPORT: The START button starts the exporting process. It will export at the framerate determined by the console command re_export_frame_rate. It will also export depth-of-field images (as a separate image sequence). It will export the number of seconds (game time) you've selected in the drop down box. If you want to export some alternative number of seconds, you would need to use the console and type "re_export <seconds>" (without the quotation). For example: re_export 11 8. SECONDS: A convenient way to set the number of seconds you want to export. KEYFRAMES Keyframes are essentially "key" frames that determine a camera's path. By adding a keyframe, you're telling the game to have a camera at whatever given point-in-time, place, angle, and/or fov that you're currently at. Then at a different point in time and place, you may set another keyframe. The replay editor will then linearly interpolate (or "lerp") between the two points (time, position, angle, and fov) to make the camera's movement look smooth. How these keyframes are used to create a camera path is demonstrated in the video below, "Creating a simple camera in Reflex Arena's replay editor". IMAGE SEQUENCES Once the exporting is completed, you will have a new folder in your Replays folder named the same as the replay you're exporting that contains the image sequences. There will be a folder called "colour" for all the normal, color images. If you've also selected DEPTH, there will be another folder called "depth" which contains the depth of field image sequence. You will need some software to combine the image sequences into a movie file. I believe there's quite a few out there but a free, easy to use program that I prefer to use is VirtualDub. To do this with VirtualDub, open the first image in the image sequence folder, colour or depth (File --> Open Video File), set the desired frame rate (Video --> Frame Rate), and then "Save As AVI". NOTE: Keep in mind that VirtualDub does not compress the images at all! It simply combines the images into a sequence in the AVI file format. Therefore, the AVI file size should be at least as big as the sum of all the image files which, depending on the length and resolution of the images, could be multiple GBs in size! AUDIO Unfortunately, I do not believe Reflex Arena's replay editor can currently export audio clips with the image sequences. Getting the audio will need to be done separately from the EXPORT process. To accomplish this, you'll need to play the replay at whatever speed you're exporting at (e.g., 25% speed or re_speed 0.25) and capture the audio with some capture software like Dxtory.
