video playback unstable
Hey guys,
I'm having a lot of trouble with trying to get video playback to work properly in reaper, as it seems to stop and stutter quite frequently which, as you can imagine is a nightmare when trying to sync it with audio. Reaper is unable to find the VLC decoder no matter where it's file is placed, don't know if this is anything to do with it. If I'm honest at this stage I have no idea what the problem can be and wondered if any of you could help. Thanks, Rowan. |

Simply install VLC in the default manner. That way Reaper will find it. You don't have to place anything.
32-bit VLC for 32-bit version of Reaper, 64->64.

@Airon
FYI: Links in the OP to the ffmpeg.zeranoe.com build packs point to version 1.2.11 rather than 3.0.1 Thanks for this thread, BTW!

Can you all recommend render settings to get a near lossless output closer to the size of the original source files?

I do not know.
The next codec to test could be MJpeg at quality 95. I'd need to test. Quicktime ProRes is available via FFMPEG, but it seems, not in Reaper. Perhaps that would be good for near-lossless output, and so fast that using just a single core on video rendering does not matter.

Thanks, Airon. I may give that a try.
I did try using MKV, H.264 @ 95% and PCM 24 bit and the resultant files were 6.08 GB compared to the original files which were 5.27 GB. I haven't had a chance to compare the quality though. I'm not working professionally, so I just need a trade-off that's good enough and file sizes that I can work with. On a 3 min video, I imagine that lossless file size would be no problem, but for over 2 hr's worth of video, I just don't have the computing power and patience to deal with 60+ GB files. This is like mixing audio with MP3s. The source files have already been compressed, and there's no way around it. The camcorder had already compressed the file to MPEG-1/2 (mpgv) 720x480. So, I'm just trying to retain a comparable quality output. I think if I want to prevent the DVD Authoring (DVDStyler) software from re-encoding the video and compressing it again then I have to use MPEG 1 or 2. I don't know which because the documentation for DVDStyler is not very good. Also, DVDStyler will compress it more if I cannot get the file size down to the destination media which will be DVD5 (needs to be not more than 4.6 GB). I believe that if the files are the correct codec and size that DVDStyler will throughput the video. I tried DVD Flick, but DVD Flick does not allow custom chapters (skip forward points) like DVDStyler does. DVD Flick can add chapters every so often, but in DVDStyler you can define exactly when each individual chapter should be rather than every 10 min or whatever.

There are also solutions that encode MPEG2 files for you. You may want to take a look at this forum for all the help you're likely to need: https://forum.doom9.org/. On that forum you'll find plenty of free tools and encoders for producing your video. Videohelp.com is great too. Here's a good post about a free MPEG2 encoder: http://forum.videohelp.com/threads/3...-MPEG2-encoder Reaper is slow, and since space is cheap and you can make smaller files for archiving from that large master file as well, it's a decent solution. For archival, I'd recommend H264 at 50 MBit for 1080p/60fps material. 25 MBit might be ok for 30fps, but go higher if possible. And keep the soundtracks in a separate file if possible if you want to edit with that stuff later on. FFMPEG with its many frontends might be what you need. Video to Video converter, Avanti, WinFF and so on. Plenty to find. Handbrake is mainly for H264 and H265 encoding as far as I know.

Thanks for those resources. I'll look into it.
I suppose, my question now is: Are the lossless options the very fastest render option for Reaper? I mean, if it takes 30 min to render the lossless file then another 30 min in another program to convert it to the destination format, or it takes Reaper 1 hr to render the destination format directly, then what's the difference? I'm going to be using free conversion and DVD authoring software on Windows 10, so no matter which option I choose it looks like the FFMPEG libraries are what's being used regardless which software I select. So, I suspect the quality of the final file should be similar so long as the same codec options are available for selection. For instance, you recommended H.264 @ 50 Mbit which I assume is a recommendation for other encoding/conversion software since Reaper only lets you choose a % value for that codec. I apologize if this has all been covered already. This thread is really long now. Thank you so much for your help!

Black Magic Output
Hey all,
Just wondering if anyone has had any success with playback of h264 with a hardware decoder like the Black Magic Cards that are offered today? I have a powerful PC but still have issues with smooth playback without transcoding. J |

I think video and reaper not for me
I never can use video and reaper on my old pc, doesn´t runs well.
Now I got a new pc, 6800k and still doesn´t works. I tried all things of those pages, vlc, ffmpeg, mkv... nothing works for me, video and audio stops and there is no sync into audio and video... the video is synced with audio, but if I opens it into reaper runs not synced...I can render and open video in another program to play and is synced... Into reaper playback has a lot of stops (audio and video)... This comes video to unusable into reaper... Runs well for audio, as always, but runs terrific with video, as always... |

reaper video is not for real time viewing. just for exporting. because it plays original size and it don't downsample video for preview.

It works, but if the video is more than 1080px or there are more at the same time it will not work. You can compare waveform to make it in sync. Reaper is not for preview but for render!

No. Why 60 frames? You need to slow down?
Use 25 frames rather. It of course depends on what computer you have. Because other programs downsample for preview they of course do that action easier, but you usually do not need full preview, just render, wait and view if it is ok.

I wish REAPER could export directly to x264 with the option to specify the command parameters, or even better with access the x264 configuration dialog, without the need to export to loseless huge file and then finish the encoding in handbrake or similar. Am I dreaming too much?

Lawrence, I know your post is old, but if I'm understanding you correctly, there is a simple fix: Using some third-party app, separate / convert the audio from your video. (On a Mac, you can use Quicktime.) Lay that audio below the Video track in Reaper, on another track. Then just pull-down the volume of the video-audio track, to zero, but keep both tracks open. -------------- You now have audio that's independent from the video. You can chop, move, whatever, and still render at the end. |

If you want to do it in advance you can use Vordio. The demo will let you do this.

Maybe we can cook up a solution ourselves that way. FFMPEG would give us a LOT of good options. I could put timecode on the frame of the video, and export a no-audio Prores Proxy Quicktime-container video. I usually do the Prorex Proxy encoding via TEncoder, which uses FFMPEG, but it doesn't have timecode displays. For that I'd have to use Avisynth, and that's hard to setup I find.

Low Framerate on Video Playback
Hey there, only just started using Reaper and would love some help.
Video playback is very choppy, FRAPS says the video inside Reaper is at 11FPS, when it should be at 30FPS (the video works fine outside Reaper). Using Reaper 5.4 64bit, Windows 10, SSD, 16GB Ram, M-Audio Fast Track Ultra Pro, project is completely empty except for the video. I've tried - Different codecs (FFMPEG, VLC and QT), Increasing buffer size, Using MP4, JMPEG, Prores on various qualities, Removing audio portion out of the video file, Disconnecting 2nd monitor that uses integrated graphics card, Unchecked colorspace and high-res peaks options, Unchecked enhanced video renderer, made sure FPS option is correct. All this and its still bottlenecked at 11fps. Any help would be greatly appreciated. Thanks. |

Hi,
To start with the simplest, are you sure the project is not set to 11 fps? You can set video frame rate in the Video tab of Project Settings (alt+Enter). |

What type of video is this ?
Play it in Mediaplayer Classic (one of its versions) or VLC and copy/paste the media information here. That'll give us container, codec for video and audio and so on. Reaper 32-bit needs the 32-bit version of VLC. 64-bit/64-bit. A good thing to check is the Source Properties of the video item. That will give you information, and tell you which playback engine is actually being used by Reaper for this video.

How to make video preview as fast as possible?
Hi, sorry if this has been asked before, but I'm a sound designer and often have to make sounds synchronizing to videos of animation, but after a lot of experimentation with video resolutions, file sizes, and formats I still can't get the video preview to work lagless 100% of the time. Can anyone give me some pointers? Thanks in advance!
For reference, currently I'm using FFmpeg to downscale source footage to 320p 500kpbs with the H.264 codec, and I usually get 1~2 seconds of buffer time on playback or seeking (down from up to 10 secs with source videos). P.S. If I use the "delay video playback" setting to allow the video to buffer, would I have to delay the audio by the same amount to sync properly? I've tried it with large values to experiment but can't tell if it's the setting working properly or just usual lag. |

Try using this format:
Quicktime container ProRes Proxy Codec (quality between 12 and 20 is fine) Use this transcoding tool, TENcoder. It's free and fairly easy to use. Get it at these websites: https://portableapps.com/apps/music_...coder-portable https://www.videohelp.com/software/TEncoder http://codecpack.co/download/TEncoder.html The files may be large, but they'll work, if you use VLC as the playback engine. I use 1920 x 1080 at 60 fps on my machine, and it works well. Check the first post for more information on that.

After looking up why this codecs works so much better, I found that my approach (trying to compress the video as small as possible) was actually the opposite of how the problem should be solved, here's an article on the matter that should help any future readers of this thread: http://telestreamblog.telestream.net...hen-editing-2/ |

Mp 4
Hi a little and fast question.
I'm really busy these days and have few time for web searching. Is it posible to video export straight from Reaper to mp4 format ? I use Airon suggestions and Handbrake so are Two steps and a big Avi file first from Reaper. Thanks ¡¡¡ |

Btw, I recommend using the container MKV. AVI can only take 16-bit PCM audio, but MKV can take anything. 16-bit is fine really . I just prefer MKV because all kinds of tools are available to process and create those files as well. MP4 and AVI are quite limited. One format for sharing video quickly for demonstration purposes is WEBM with the VP8 video codec and OGG audio. ANY web browser can play this file natively(not just VLC), because WEBM with VP8(and VP9) is a supported standard. Youtube actually uses VP9(Video) and Opus(audio) for streaming. VP8 encodes fairly quickly. VP9 is very slow. Reapers severe limitation is that it tries to encode video with just one CPU core. Thus, Handbrake saves you time for a good quality final master, and all it costs is a couple of GB of hard disk space, temporarily. Handbrake can encode VP9 as well now btw, and Opus. It even comes with presets for that.

Hi guys,
I am using a portable version of Reaper x64. I have noticed that even if I copy latest FFmpeg dlls, Reaper seems to use \Plugins\FFmpeg.dll, which seem to be older. Does this mean FFmpeg is somewhat included with Reaper install?

It's better to post my question here, added to this topic:
I've been using Reaper for years with live video on stage from within the timeline. Now I started a new project and I've found out that this video takes more CPU than expected. I'm not sure if it's due to my new laptop (new drivers, new windows new vlc), or due to the video format (mp4 720p). Suddenly my CPU shoots up an extra 10% only with the video. Any of you got any ideas what gives the lowest CPU or how to solve my prob? What are the required settings or decoders needed?
