Default Rendered Video Replays at Twice Speed

Can anyone help? I render my tracks and sound plays back perfectly but Video is 2x . I have Reaper 4.57/x64 I use the following formats on separate tracks:

Video = Mp4
Guitar= Wav
Drums and bass= Mp3

I have same problem using different formats.

I am hoping its simply me being an idiot and not getting the settings correct! Hope some can help. Thanks. Chilldock.

Can you post your video render settings?

Those settings look reasonable to me (although I would up the video bit rate to 6000 kbps at a minimum).

Can you give more info about the source video? You can use mediainfo http://mediaarea.net/en/MediaInfo to get details.

And use "Source Properties" in REAPER to identify the version of FFmpeg you're using.

Finally, is there any way you can make a very short sample clip available from your camera, perhaps through dropbox or even email?

If you're not editing the video itself, you're better off making an MP4 file with the new audio track and the old video. This is called muxing, as opposed to encoding.

To do that, render your audio mix across the length of the video to a 24-bit WAV file. Then encode that to an AAC file(160 kbit or more suggsted) with Nero's free AAC encoder for example.

Take your original MP4 and your new AAC audio file, and use a tool like YAMB, a frontend for MP4box, to combine those files in to a new MP4 file without having to reencode the video. Another frontend is My MP4Box GUI.

Reaper is rather simple when it comes to video encoding.

If you just need to send something quickly, and the other person has VLC for playback or just Firefox for that matter, use WEBM as the target format instead. It presents the least problems and gives you immediate results. VLC and Firefox will play WEBM videos.

Hi Guys,

I'm an old reaper user who got outta the game about 3 years ago and I came back to do some minor audio editing in video....The problem is I just bought a new computer HP ELITEBOOK win 7 and when I installed my reaper program it won't let me play mp4's anymore....

I have done every kinda of mix n match with the codecs and the programs i had wroking and it has not prevailed...I could play mp4's in my old ADK no problem but now nothing...

Right now I have a clean install with my old 3.76 version of reaper (I have the paid license for that)and I have tried your codecs and it is still not working...

Any Ideas?

Cheers, jeff

It's probably a version 4 thing. Reaper 4 can use VLC for playing videos, and Reaper 3.... I honestly haven't the faintest which version required which FFMPEG library and whether or not that even worked properly.

You might want to do your editing with a 60 day trial of Reaper 4, install VLC (32-bit Reaper -> 32-bit VLC installation and so on), and get it all done.

Sorry for the stupid question but, as far as i understand, should i install that "Handbrake" to be able to edit video in Reaper?

I'm now trying to put mov files in Reaper but nothing seems to work

Handbrake is a conversion tool. airon suggests converting videos to make them more responsive. I've had good luck without converting most of the formats I use.

What have you tried in order to work with video? Installed VLC? Installed FFmpeg? Changed default decoder in Preferences?

Nothing. Just putting a .mov file inside the project (i needed to try)

Then what's the easier way?

Thanks

I have my Preferences - Video/REX/Misc - Preferred video decoding engine

set to OS Native

and when I drag and drop a .MOV clip into REAPER it loads. I press Ctrl+Shift+V and a video window opens and I'm in business.

What have you tried? What was the result? Do you have QuickTime installed?

Default Is VLC sufficient for video playback

I just did this and yes it was sufficient for playback. However to render a video I needed to install the Aegiscorp ffmpeg.

Ok i did both and... voilá! All is working now.
Cool.

But a last issue is that i tried to put an image (a logo upfront the video to combine both) and nothing seems to occur. Is it not possible?

Also seems to be unable to make a fade out in the video clips.

It took me hours to solve and I'm not sure how they're related, but changing buffer size to 512 fixed it for me.

Default Sound Quality Issues When Rendering MP4 with AAC audio

Hi all,

Is anyone else having issues exporting an MP4 with AAC? I need to send the director a preview, so I am using a bitrate of 320kbps on my AAC codec, and it sounds *very compressed. Like, as in Real Player circa 1996...

I switched the audio codec from AAC to MP3, while keeping the same bitrate and wow - what a difference: the audio sounds great...

I have the same issue here when I convert a video using H264 with AAC 320kbps or any other AAC bitrate. The high frequency are phasing like a bad mp3. I've tried to use Airons's method on the first post :

MKV container
FFV1 video codec (lossless)
Huffyuv video codec (lossless)
16, 24 or 32-bit PCM audio

but Reaper stops responding and I have to force quit.

Same here. Aac is definitely not up to scratch even at a high baud rate.

I do the crazy thing and use wav 16bit (make sure to set kbps to 1411 I think it won't be right)

This gives uncompressed sound I recommend VLC playback.

Just tried and still, REAPER stops responding as soon as I am rendering a video (QT,MOV, MP4) with choosing a 16 or 24bit PCM audio.

I have always assumed that selecting PCM overrides the bps setting, and it seems to have worked just fine.

Me too. I'm wondering why the kbps box doesn't disappear when choosing 16-24-32bit PCM audio.

I meant 1411 not 1141 sorry I can't remember if it's actually needed but I'm sure it helped with crashes.

I was getting that same freeze but don't get it with the below settings.

format: [QT/MOV/MP4]

Video codec: [H.264] bitrate [11391]

Audio codec: [16 bit PCM] Bitrate [1411] kps

The video bitrate works fine for most of what I do but find what works for your needs)

That audio bit rate is only right for 16bit stereo 44.1khz. and you'll have to do a search for working it out for 48khz etc.

it might not even make a difference but I'm sure I tried it without.

Also, here's version info from the source properties on an item decoded with FFMPEG. Hope that helps.

Loaded from: C:\Program Files\REAPER (x64)\avcodec-54.dll

I will say though, near the end of creating the file (last 10 percent) it can get stuck for a minute max as it sorts out stuff but then it finalises and all is good!

If I understand correctly, the included AAC encoder (libvo_aaenc) is considered a poor encoder compared to other on this page: https://trac.ffmpeg.org/wiki/Encode/AAC

The WIKI entry on Reapers video support has been updated with information on Reaper 5 pre-release versions.
http://wiki.cockos.com/wiki/index.php/Video_Support

The pre-release version can be tested over in the Pre-Release forum section now. It's a bunch of great detail improvements for video users, including a dockable video window, accurate time rulers for SMPTE timecode and much improved decoding for OSX users(build in to the operating system!!!).

Airon, as I know you have been following the video features of Reaper very closely. Can I ask if AAF/OMF import from NLE has been discussed? It would be very handy especially for mac users who do not have native access to AATranslator. Cheers.

Hi, I'm running Reaper64 on OSX, and I've tested this both on Mavericks and Yosemite.
The problem is that videos in Reaper just feel really sluggish. Seeking is really slow compared to using the same files in Logic X, where it's very fluid. I'm also often experiencing video-freezes, where restarting Reaper seems to be the only option. I've tried H264, MJPEG A and PhotoJPEG. I've tried all the different decoders, and also the new avfoundation decoder in the v5 pre-releases (restarting Reaper between testing them). Any tips? Is the avfoundation decoder the same that Logic uses?

Anyone else experiencing slow seeking? At least switching back to VLC seems to have stopped the video-freezes. I'm sure avfoundation will improve with further Reaper 5 development.

Yesterday, VLC v2.2 was released. Anyone using this version won't be able to use it with Reaper.

Quote:
Available decoder information:

========== VLC ==========
VLC 2.0.x or 2.1.x not found -- search path:
C:\Program Files\VideoLAN\VLC
I checked the path is valid.
Anyone following Airon's guide to get VLC from http://download.videolan.org/pub/videolan/vlc/last/ will experience problems.

Instead, use this version of VLC: http://download.videolan.org/pub/videolan/vlc/2.1.5/

Default OSX Video Export problem

Hello all,
today I tried for the first time to export a video from Reaper. The idea is to send the director some video previews of the work I'm doing by selecting portions (= scenes of the film) of the project. I installed (successfully) the ffmpeg codecs posted by Airon on the sticky post. I never had (big) video-playback issues.

Reaper 4.76, 32bit on OSX 10.7.5

My render settings are:
- QT cointainer, h264 codec. (I have no other codec options)
- mp3 audio
- 25fps

Source File:
Video: 640x360@25.00fps, Aspect=1.00, Decoding format=RGB

Using FFmpeg DLL decoder v54.43.100
Video: mjpeg (jpeg / 0x6765706A), yuvj422p, 640x360 [SAR 72:72 DAR 16:9], 6974 kb/s

Loaded from: /Users/sluca/Library/Application Support/REAPER/UserPlugins/FFmpeg.dylib
FFmpeg configuration:
--enable-gpl
--enable-shared
--arch=i386
--extra-cflags='-m32
-isysroot
/Developer/SDKs/MacOSX10.4u.sdk
-mmacosx-version-min=10.4
-I/usr/local/include'
--extra-ldflags='-m32
-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk
-mmacosx-version-min=10.4'
--enable-runtime-cpudetect

Project framerate is set to 25fps:

The problem is that the video runs faster than it should and as it finishes, freezes the last frame. The sound is perfect.
It also creates a "longer" video than the selected portion. The exceeding portion shows the last frame of the video and no sound.

I really need the output to be a MOV or MP4 file, so other containers aren't an option.

Anyone else experiencing the same problem? Am I doing something wrong? Are there other FFmpeg dist. with mp4 option?

Thank you a lot!

Updated the first post with FFMPEG library recommendations for encoding video directly from Reaper in Windows.

Reaper 5.0 for OSX does not need this, since it can use the system libraries AVFoundation to encode videos directly. I recommend you use the most recent Reaper 5.0 pre-release, which is currently at v5.0pre32, available through the Pre-Release forum section. It is open to everyone.

Hi,
I just want to playback video in Reaper and therefore am trying to use VLC. But obviously the VLC installation is not recognised by Reaper - certain video formats like mp4 can't be played. I'm using 32-bit reaper (4.78) and 32-bit VLC (2.2.1). Also I tried an older version of VLC as Reaktor:[Dave] suggested:

I checked the path is valid.
Anyone following Airon's guide to get VLC from http://download.videolan.org/pub/videolan/vlc/last/ will experience problems.

Instead, use this version of VLC: http://download.videolan.org/pub/videolan/vlc/2.1.5/
Does anybody have a clue how to solve it?
Or am I getting something wrong? Do I have to use some further libraries?
I installed VLC into its usual folder (c:/program files/Videolan/VLC) - is there like a settings file in reaper to point it to a different folder? Btw. does reaper seek for a VLC installation?

THANKS for your help!!!
