If it is too long for You, please f3 Your question.
It says my ffmpeg is not installed!
First, FFMPEG is not a Minecraft mod.
Check this out or this for informations.
CRASH: Tesselating block model (when loading a world/replay)
Please downgrade Forge to version between 1487 and 1521. This issue is caused by shaders mod compatibility problems with Forge, not by the Replay Mod.
"-- Compatible with Forge 1487 to 1521. Not compatible with Forge 1523 or later" - quotation from shaders mod forum thread.

Look at this post.
How can I save my paths?
If You like video explanations check this video by CrushedPixel, if You like reading click this link.
My Minecraft crash when i render!
This may be caused by many things, first check if You still have some space on the disk, if You have then check the documentation.
I can't move when Replay is paused!
Check Your key settings, make sure there are different keys for every action, make sure You don't have any special (other than a-z or 0-9) keys assigned to actions.
I don't hear sounds in rendered videos
There is no support for that atm, but it may be added in future.
My 360º Video is partially cut!
You probably used post processing software on render from the mod, if so please don't change the resolution of video.
I crash when i try to open a Replay.
It's possible You use other incompatible mod (for example Map Writer mod).
When i'm in the replay i don't see my mouse.
Click "t" button.
I'm stuck in a player! I can't leave his first person view!
Use Your sneak button (default "shift").
How to do 360º video?
If You want to create 360 video and upload it on Youtube, You need to use equirectangular rendering option and then inject some metadata. More info can be found in the documentation here!
World is crazy, chunks flashing, people dying.
It's probably Minecraft bug if You have ADM graphic card. Turn VBO option on, lower Your render distance or update drivers.
How can i hide UI/GUI?
You can toggle UI by clicking F1 button, like in vanillia Minecraft. You can use this trick to record something with shaders in Replay Viewer (not really that convinient + shaders have no official support atm so it may and will be buggy) or make screenshots.
Why is my camera path going in weird directions?
You probably set two position keyframes close to each other and You are using cubic interpolation. Change Your path Interpolation to Linear.
Nothing is moving in my render/path preview.
Make sure You have more than one Time Keyframe and all of them have different timestamps. More info in the documentation.
Mobs and players are invisible.
Change Forge version, delete mods and try again.
I have Custom Main Menu mod, what ids are for the buttons?
See this post.
Crash on startup.
Replay Mod works only with 1.8 versions of Forge. Any 1.8> version of forge will result in crash.
Don't drink and ReplayMod. Jokes aside, this is probably due to compatibility with another mod. Please create a new thread and make sure to include the following:
Please post the contents of the fml-client-latest.log
