Default Questions about video in REAPER 4.14

Hi and merry xmas to everyone,

Hi I was wondering about a few things, I guess no one will answer untill january because of the holidays but anyway:

I want to ask what is the best video format (the one that reaper accepts most gracefully)ideally for scoring work mov or mp4 h264 would be awesome since AVI can get so heavy but I've imported such format (mov) and I get sometimes a black screen or sometimes it plays well but when reaching to the end of the video in the time line and rewinding I get the black video output again this happens when I either manually rewind of with a loop activated.

and a second question is this: where do you adjust the frame rate of the project in reaper? to match the video you are working with

thanks in advanced.

Default Xvid

Hi, I'm on Windows and uses Xvid which can be rendered by use of Directshow - if you have the codec installed. I use Xvid because the decoding doesn't stress my CPU to much and the file size is not to big.

For the transcoding part, I use FFmpeg. FFmpeg can transcode from just about any format - now even ProRes, and make a Xvid video output. I use FFmpeg with the following parameters:
ffmpeg -i input.mov -g 2 -s 768x432 -an -qscale 3 output.avi

-g 2 means that the GOP size is 2 - that makes every 2nd frame a keyframe, so skipping is easy for Reaper. -qscale denotes the quality - less makes bigger files. I only use 768x432 pixels which is big enough for my purpose.

Get FFmpeg for Windows here:

Get Xvid codec here:
http://www.xvid.org/Downloads.15.0.html

Regards,

Frederik

I think I might have discovered a bug with the 64bit version of REAPER for windows, I did what you told me and converted my video file, and nothing I couldn't see it, I tried seveal of the video options in REAPER but then it ocurred to me to download and installed the 32 bit version and I tried and the video works like a charm but reaper reports it like 23 fps and Quicktime 24 fps but other than that it loads the video out of the box. So I will need to use the 32 bit version. (should I report this?) - although I've been using REAPER for a little while now, I haven't been active in the forums I think I will now.


any suggestions whether this is a bug or not?

HELP - I want to install xvid/FFmpeg codecs, how? where? I downloaded the codecs from the link you provided, now what??? sorry to be such a noob but I'm really stuck... What video codecs does Reaper use? how can I change them now that I am having so many video issues??? I sent a bug report but I'm sure Reaper is capable of much better video results if I can use the proper codecs... I hope you can help.... Don

FFmpeg is a command line tool. If you need some GUI based program try SUPER:
